Jennifer is 3 years older than twice Zack’s age. The sum of their ages is 21. What are their ages?
Answer:
Jennifer is 15 and Zack is 6
Step-by-step explanation:
z+ (2z+3)=21
z+2z+3-3=21-3
z+2z=18
3z=18
3z/3=18/3
z=6
so plug 6 in for all the variables and their ages are
Zack-6

This is a addition problem. You need to add three fractions, so you need a common denominator.
The LCD is 2, 4, and 8 is 8.
3/4 + 5/8 + 1/2 =

= 15/8
= 1 7/8

What is the slope of the line that passes through the points (-2,8) and (-22,8)? Write your answer in simplest from
Answer:
[tex]\boxed{\tt m=0}[/tex]
Step-by-step explanation:
The slope formula is:
[tex]m=\frac{y_{2} -y_{1}}{x_{2}-x_{1}}[/tex]
where (x₁, y₁) and (x₂,y₂) are the points on the line.
The points given are (-2,8) and (-22,8). Therefore,
[tex]x_{1}=-2\\y_{1}=8\\x_2=-22\\y_2=8[/tex]
Substitute the values into the formula.
[tex]m=\frac{8-8}{-22--2}[/tex]
Solve the numerator. Subtract 8 from 8.
[tex]m=\frac{0}{-22+2}[/tex]
Zero divided by any number is zero, so we automatically know the slope is zero.
[tex]m=0[/tex]
The slope of the line is 0
Answer: 0
Step-by-step explanation:
To find the slope, you need to use the formula [tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]. You use the given points to plug in and solve.
[tex]m=\frac{8-8}{-22-(-2)} =\frac{0}{-20}=0[/tex]
Now, we know that the slope is 0 meaning this is a horizontal line.

-9 - 5 "add my positive add my negative"
Answer:
-14
Step-by-step explanation:
The answer is -14 because:
1) First, we need to know that:
negative x negative = positive
negative x positive = negative
positive x negative = negative
positive x positive = positive
2) -9 - 5 is negative times negative which makes it 9 + 5 = 14
3) Since the number with the negative sign is greater, the answer is -14

L is the midpoint of KM. If KL = 14x and KM = 26x + 14, what is KL? Simplify your answer and write it as a proper fraction, mixed number, or integer. Please type the answer step by step.
Answer:
Step-by-step explanation:
L is the midpoint of KM. So, length of KL = length of LM
KL = LM = 14x
KL + LM = KM
14x + 14x = 26x + 14 {add the like terms}
28x = 26x + 14 {subtract 26x form both sides}
28x - 26x = 14
2x = 14 {divide both side by 2}
2x/2 = 14/2
x = 7
KL = 14x = 14*7
KL = 98

solve for x, UV and TV
We know that TV = TU + UV. Let's plug the values from the picture into our equation.
x + 25 = 9 + 2x + 28.
Let's combine like terms on the right side.
x + 25 = 2x + 37
Subtract 37 and x from both sides.
-12 = x
TV = x + 25 = -12 + 25 = 13
UV = 2x + 28 = 2(-12) + 28 = -24 + 28 = 4

A candy maker produces mints that have a label weight of 20.4 grams. Assume that the distribution of the weights of these mints is normal with mean 21.37 and variance 0.16. a) Find the probability that the weight of a single mint selected at random from the production line is less than 20.857 grams. b) During a shift, a sample of 100 mints is selected at random and weighed. Approximate the probability that in the selected sample there are at most 5 mints that weigh less than 20.857 grams. c) Find the approximate probability that the sample mean of the 100 mints selected is greater than 21.31 and less than 21.39.
Answer:
a)0.099834
b) 0
Step-by-step explanation:
To solve for this question we would be using , z.score formula.
The formula for calculating a z-score is is z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.
A candy maker produces mints that have a label weight of 20.4 grams. Assume that the distribution of the weights of these mints is normal with mean 21.37 and variance 0.16.
a) Find the probability that the weight of a single mint selected at random from the production line is less than 20.857 grams.
Standard Deviation = √variance
= √0.16 = 0.4
Standard deviation = 0.4
Mean = 21.37
x = 20.857
z = (x-μ)/σ
z = 20.857 - 21.37/0.4
z = -1.2825
P-value from Z-Table:
P(x<20.857) = 0.099834
b) During a shift, a sample of 100 mints is selected at random and weighed. Approximate the probability that in the selected sample there are at most 5 mints that weigh less than 20.857 grams.
z score formula used = (x-μ)/σ/√n
x = 20.857
Standard deviation = 0.4
Mean = 21.37
n = 100
z = 20.857 - 21.37/0.4/√100
= 20.857 - 21.37/ 0.4/10
= 20.857 - 21.37/ 0.04
= -12.825
P-value from Z-Table:
P(x<20.857) = 0
c) Find the approximate probability that the sample mean of the 100 mints selected is greater than 21.31 and less than 21.39.

Use rounding to estimate the product of 198 and 42 . Round both numbers to the nearest ten to find your answer.
Answer:
8000
Step-by-step explanation:
198 and 42 rounded to the nearest hundreths are 200 and 40. the product of 200 and 40 is 8000
The product of 198 and 42 rounded both numbers to the nearest ten
is 8000.
What is rounding off of numbers?We round off numbers to make them easier to remember and it also keeps its value approximately to the place it has been rounded off.
To round off any number to any place we'll look for the digit next to that place and if it is equal to or greater than 5 we'll add one to the previous digit and make all the digits after it zeroes and if the digit is less than 5 we do not add one to the preceding digit and simply make all the digit after it to zeroes.
Given, Use rounding to estimate the product of 198 and 42.
Now, 198 rounded to the nearest ten is 200, and 42 rounded to the nearest ten is 40.
Therefore, The multiplication of 198 and 42 rounded to the nearest 10 is,
= 200×40.
= 8000.

Your cost for each light saber is $2.45 plus you have to pay a fixed weekly fee of $250 for the booth. You plan to sell each light saber for $4.15.
Write an expression that represents the profit for selling (n) light sabers in a given week.
How many light sabers must you sell in order to make a positive profit? (Profit>=0)
In order to make a positive profit, you would have to sell at least (blank) light sabers.
$4.15n - ($250 + $2.45n)
Now that we have our expression, let's set it greater than or equal to 0
$4.15n - ($250 + $2.45n) >= 0
Let's simplify the left side.
$4.15n - $250 - $2.45n >= 0.
Combine like terms.
$1.7n - $250 >= 0
Add $250 to both sides.
$1.7n >= $250
Divide both sides by $1.7
n >= 148
You would need to make 148 light sabers to make a positive profit.
For a certain city, the temperature each day this week can be described by the inequality below.
3d +6<A
In the inequality, d is the daily temperature in degrees Fahrenheit and A is the average temperature for the year. If A = 54 °F, which statement BEST interprets the solution to the in
A The temperature each day this week was less than 90 "F
B The average temperature for the year was less than 90 °F
c The temperature each day this week was less than 72 °F
DO The average temperature for the year was less than 72 °F
Answer:
Option C.
Step-by-step explanation:
We have the following inequality :
[tex]3d+6<A[/tex] (I)
In which :
[tex]d[/tex] : '' The daily temperature in degrees Fahrenheit ''
[tex]A[/tex] : '' The average temperature for the year ''
We first need to find the solution (the inequality related to the value of [tex]d[/tex]) given that we set [tex]A=54[/tex] °F ⇒
Using the equation (I) :
[tex]3d+6<54\\3d<48\\d<16[/tex]
We find that the ''[tex]d[/tex]'' variable (daily temperature in degrees Fahrenheit) is less than [tex]16[/tex] °F.
The option B and the option D give us an interpretation about the [tex]''A''[/tex] variable.
Only the options A and C give us an interpretion about the [tex]''d''[/tex] variable
Between A and C, the option C is a more accurate option (because 72°F is closer to 16°F).
We answer that the option C best interprets the solution.

If the standard volume of a
cube is 1.5cm³ calculate the
cm
percentage error in measuring its
volume which is found to be 1.6cm³
A:6.7%
B:-6.7%
C:5%
D:-5%
E:4%
Answer:
6.7 %
which agrees with answer A in your list.
Step-by-step explanation:
If the standard volume is 1.5 cubic cm, and the measured volume is 1.6 cubic cm, then the difference between these two is :
1.6 - 1.5 = 0.1 cubic cm. and therefore the percentage error is given by:
0.1/1.5 = 0.066666...which corresponds to a rounding of 6.7%
Recall as well that percent error is always expressed as a positive number.
