Nicole, Miguel, and Samuel served a total of 115 orders Monday at the school cafeteria. Miguel served 3 times as many orders as Samuel. Nicole served 10 more orders than Samuel. How many orders did they each serve?
Answer:
Samuel = 21 orders
Nicole = 31 orders
Miguel = 63 orders
Step-by-step explanation:
Let N represent Nicole's orders, M represents Miguel's orders, and S represent Samuel's orders.
We know that the sum of their tree orders equals 115 as
N + M + S = 115
Since Miguel served 3 times as many orders as Samuel, we know that
M = 3S.
Since Nicole served 10 more orders than Samuel, we know that
N = S + 10
Samuel's Orders:
Now we can plug in 3S for M and S + 10 for N to find S, the number of Samuel's orders:
S + 10 + 3S + S = 115
5S + 10 = 115
5S = 105
S = 21
Thus, Samuel served 21 orders.
Nicole's Orders:
Now we can plug in 21 for S in N = S + 10 to determine how many orders Nicole served:
N = 21 + 10
N = 31
Thus, Nicole served 31 orders.
Miguel's Orders:
Now we plug in 19 for S in M = 3S to determine how many orders Miguel served:
M = 3(21)
M = 63
Thus, Miguel served 63 orders.
Which of the following gives the correct range for the piecewise graph?
A coordinate plane with a segment going from the point negative 3 comma 2 to 0 comma 1 and another segment going from the point 0 comma 1 to 5 comma negative 4.
The correct range for the piecewise graph is [-4, 2].
To solve this problemWe need to find the minimum and maximum values of the y-coordinates.
The first segment goes from (-3, 2) to (0, 1), so the range for this segment is from 1 to 2.
The second segment goes from (0, 1) to (5, -4), so the range for this segment is from -4 to 1.

Find the area of the parallelogram
The area of the parallelogram is 189 square units
How to determine the areaFirst, we have the determine the length of the base and height.
The distance between the lines x = 9 and f(x) = 9 + 2x is the height
We have that the line parallel to f(x) passes through (4, 11)
The equation in point-slope form is;
y - 11 = 2(x - 4
y = 2x + 3
Substitute x = 9 in the equation, y = 2x + 3.
y = 2(9) + 3 = 21
The points are then (9, 21) and (9, 0).
The distance between the y-axis and the line x = 9 is the base.
Base = 9 units.

Ram borrowed Rs. 250000 from sit a at the rate of 21%: per annum. At the end of monts, how much should he pay compounde à half yearly ?
The end of 6 months, Ram should pay Rs. 276250 compounded half-yearly.
Ram borrowed Rs. 250000 from Sit at an interest rate of 21% per annum. To calculate the compound interest, we need to know the compounding period. In this case, the interest is compounded half-yearly, which means it is calculated twice a year.
To find out how much Ram should pay at the end of 6 months, we can use the compound interest formula:
A = P(1 + r/n)^(nt)
Where:
A = the amount to be paid at the end of the time period
P = the principal amount (the initial amount borrowed) = Rs. 250000
r = the interest rate per period (in decimal form) = 21% = 0.21
n = the number of compounding periods per year = 2 (since it's compounded half-yearly)
t = the number of years = 6 months = 6/12 = 0.5 years
Plugging in these values into the formula, we get:
A = 250000(1 + 0.21/2)^(2*0.5)
Simplifying the equation:
A = 250000(1 + 0.105)^(1)
A = 250000(1.105)
A = Rs. 276250

Step-by-step explanation:

2) Looking at your average from question 1, with an expected weight of 4 ounces, what is the % error in actual weights? (Assume you think the answer is 10%. Find 10% of 4 ounces to check to see if that answer is reasonable!) Do not round!
A) 17.5%
B) .128%
C) 10%
D) 0.175%
The calculated percentage error with the assumed answer of 10%
To find the percentage error in actual weights, we can use the formula:
Percentage Error = [(|Measured Value - Expected Value|) / Expected Value] * 100%
In this case, the expected weight is 4 ounces. Let's assume the measured value is 10% off from the expected value. So the measured value would be:
Measured Value = Expected Value + (10% of Expected Value)
= 4 ounces + (10/100) * 4 ounces
= 4 ounces + 0.4 ounces
= 4.4 ounces
Now we can calculate the percentage error:
Percentage Error = [(|4.4 ounces - 4 ounces|) / 4 ounces] * 100%
= [(0.4 ounces) / 4 ounces] * 100%
= (0.4/4) * 100%
= 0.1 * 100%
= 10%
Comparing the calculated percentage error with the assumed answer of 10%, we can see that they are the same.
The percentage error represents the deviation from the expected value as a percentage of the expected value itself. In this case, it indicates that the actual weights deviate by 10% from the expected weight of 4 ounces. The calculated percentage error with the assumed answer of 10%

How many gallons of a 50% antifreeze solution must be mixed with 70 gallons of 10% antifreeze to get a mixture that is 40% antifreeze?
Answer: 180 gallons needed
Step-by-step explanation:
Zykeith,
Assume x gallons of 50% antifreeze is needed
Final mixture is x + 60 gallons
Amount of antifreeze in mixture is 0.4*(x+60)
Amount of antifreeze added is .5x + .1*60 = .5x + 6
so .5x + 6 = .4(x + 60)
.5x -.4x = 24 -6
.1x = 18
x = 180
Let x be the number of gallons of the 50% antifreeze solution needed. We know that the resulting mixture will be 70 + x gallons. To get a 40% antifreeze mixture, we can set up the following equation:
[tex]{\implies 0.5x + 0.1(70) = 0.4(70 + x)}[/tex]
Simplifying the equation:
[tex]\qquad\implies 0.5x + 7 = 28 + 0.4x[/tex]
[tex]\qquad\quad\implies 0.1x = 21[/tex]
[tex]\qquad\qquad\implies \bold{x = 210}[/tex]

The graph of the solution to the inequality is attached as image to this answer.
Understanding Piece-Wise FunctionThe piece-wise defined function h(x) represents different values of y (the output) depending on the value of x (the input). Each interval of x has a different value assigned to it.
In this particular case, the inequality statements define the intervals for x and their corresponding output values.
Let's break it down:
- For values of x that are greater than -3 and less than or equal to -2, h(x) is assigned the value of -1.
- For values of x that are greater than -2 and less than or equal to -1, h(x) is assigned the value of 0.
- For values of x that are greater than -1 and less than or equal to 0, h(x) is assigned the value of 1.
- For values of x that are greater than 0 and less than or equal to 1, h(x) is assigned the value of 2.
Any values of x outside of these intervals are not defined in this piece-wise function and are typically represented as "not a number" (NaN).
For example, if you were to evaluate h(-2.5), it falls within the first interval (-3 < x ≤ -2), so h(-2.5) would be equal to -1. Similarly, if you were to evaluate h(0.5), it falls within the fourth interval (0 < x ≤ 1), so h(0.5) would be equal to 2.
The graph of the piece-wise function h(x) consists of horizontal line segments connecting the specified values of y for each interval, resulting in a step-like pattern.

pears and sells them for $5 per bag. In which equation
oes b represent the number of bags of pears?
If Natalie puts 4 pears in each bag, she will be able to sell a total of 12 bags of pears at the Saturday market.
To represent the number of bags of pears, b, that Natalie sells at the Saturday market, we can use the following equation:
b = total_number_of_pears / pears_per_bag
In this equation, "total_number_of_pears" represents the total quantity of pears Natalie has, and "pears_per_bag" represents the number of pears she puts in each bag.
Given that Natalie has a total of 48 pears, we can substitute the value into the equation:
b = 48 / pears_per_bag
Now, we need to determine the number of pears she puts in each bag. The information provided states that Natalie sells bags of pears, and each bag is sold for $5. However, the specific number of pears per bag is not given. To proceed, we need this information.
Let's assume that Natalie puts 4 pears in each bag. We can substitute this value into the equation:
b = 48 / 4
Simplifying the equation gives:
b = 12
So, if Natalie puts 4 pears in each bag, she will be able to sell a total of 12 bags of pears at the Saturday market.
It's important to note that the specific value of "pears_per_bag" will affect the final result. If Natalie puts a different number of pears in each bag, the equation will yield a different number of bags sold.

(Write an equation for the cross section at
y = 9
using x and z.)
(Write an equation for the cross section at
x = 0
using y and z.)
Answer:
Step-by-step explanation:
To sketch the surface represented by the equation 9x² - y² + 3z² = 0 and find the equations for the cross sections, we can start by isolating each variable and considering different values for the fixed variables.
(1) - Cross section at z = 0:
Substituting z = 0 into the equation, we get 9x² - y² = 0 . Rearranging this equation, we have:
9x² = y²
Taking the square root of both sides, we get:
y = ±3x
So the equation for the cross section at z = 0 is y = ±3x and our trace is a line in the xy-plane.
(2) - Cross section at y = -9:
Substituting y = -9 into the equation, we get 9x² - (-9)² + 3z² = 0. Simplifying this equation, we have:
9x² - 81 + 3z² = 0
Rearranging, we obtain:
9x² + 3z² = 81
Dividing by 3, we get:
3x² + z² = 27
So the equation for the cross section at y = -9 is 3x² + z² = 27 and our trace is an ellipse in the xz-plane.
(3) - Cross section at y = 9:
Substituting y = 9 into the equation, we get 9x² - (9)² + 3z² = 0. Simplifying this equation, we have:
9x² - 81 + 3z² = 0
Rearranging, we obtain:
9x² + 3z² = 81
Dividing by 3, we get:
3x² + z² = 27
So the equation for the cross section at y = -9 is 3x² + z² = 27 and our trace is an ellipse in the xz-plane.
(4) - Cross section at x = 0:
Substituting x = 0 into the equation, we get - y² + 3z² = 0. Rearranging this equation, we have:
y² = 3z²
Taking the square root of both sides, we get:
y = ±√3z
So the equation for the cross section at x = 0 is y = ±√3z and our trace is a parabola in the yz-plane.

First, let's see how many batches of cookies Alice can make:
Flour: Alice has 2 cups, and each batch requires 3/4 cup. So she can make 2 cups / (3/4 cup) = 8/3 = 2 and 2/3 batches of cookies.
Butter: Alice has 1/4 cup, and each batch requires 1/3 cup. Since she doesn't have enough butter for a full batch, she can't make any batches of cookies with the butter she brought.
Next, let's see how many batches of cookies Maria can make:
Flour: Maria has 1 1/4 cups, and each batch requires 3/4 cup. So she canmake (5/4 cups) / (3/4 cup) = 5/3 = 1 and 2/3 batches of cookies.
Butter: Maria has 3/4 cup, and each batch requires 1/3 cup. So she can make (3/4 cup) / (1/3 cup) = 9/4 = 2 and 1/4 batches of cookies.
Now, to find the maximum number of whole batches they can make together, we take the minimum of the number of batches each student can make:
Alice: 2 and 2/3 batches
Maria: 1 and 2/3 batches
Raul: Not mentioned, so we assume he brought the required ingredients.
The minimum value is 1 and 2/3 batches, which means they can make 1 whole batch of a dozen cookies together.

PLEASE HELP. The value of "y" varies directly with "x".
If y 6, then x = 2.
Find "y" if x = 5.
k = 3
y = [?]
Answer:
y=15
Step-by-step explanation:
y varies directly as x so:
y=k(x)
y = kx
if y is 6 and x is 2;
input the values
y=kx
6=k(2)
[tex] \frac{6}{2} = \frac{2k}{2} [/tex]
k = 3
then find y if x=5
use the previous formula
y=kx so:
y=3(5)
therefore y=15
The value v of a tractor purchased for $13,000 and depreciated linearly at the rate of $1,300 per year is given by v= -1,300t+13,000, where t represents the number of years since the
purchase. Find the value of the tractor after (a) two years and (b) six years. When will the tractor have no value?
a) the value of the tractor after two years is $10,400.
b) the value of the tractor after six years is $5,200.
To find the value of the tractor after a certain number of years, we can substitute the value of t into the equation v = -1,300t + 13,000.
a) After two years:
Substituting t = 2 into the equation, we get:
v = -1,300(2) + 13,000
v = -2,600 + 13,000
v = 10,400
Therefore, the value of the tractor after two years is $10,400.
b) After six years:
Substituting t = 6 into the equation, we get:
v = -1,300(6) + 13,000
v = -7,800 + 13,000
v = 5,200
Therefore, the value of the tractor after six years is $5,200.
To find when the tractor will have no value, we need to find the value of t when v = 0. We can set the equation v = -1,300t + 13,000 equal to 0 and solve for t:
-1,300t + 13,000 = 0
-1,300t = -13,000
t = -13,000 / -1,300
t = 10
Therefore, the tractor will have no value after 10 years.

A company has 200 machines. Each machine has 12% probability of not working.
If you were to pick 40 machines randomly, the probability that 5 would not be working is
and the probability that at least one machine would be working is
the probability that all would be working is
1) The probability that 5 will be working is: 0.187
2) The probability that at least one machine would be working is: 0.006
3) The probability that all would be working is : 1
How to find the probability of working?We are given the parameters as:
Total number of machines = 200
Probability that a Machine is working = 12% = 0.12
1) Now, you want to pick 40 machines and want to find the probability that 5 will be working.
This probability is given by the expression:
P(5 working) = C(40,5) * 0.12⁵·0.88³⁵ ≈ 0.187
where C(n, k) = n!/(k!(n-k)!)
2) The probability that at least one machine would be working is:
0.88⁴⁰ ≈ 0.006
3) The probability that all would be working is the complement of the probability that all have failed. Thus:
P(all working) = 1 - 0.12⁴⁰ ≈ 1
