A survey shows that 7 out of 8 customers are satisfied with the food served at Big Joe BBQ.
Assuming the restaurant had 176 customers yesterday, how many customers probably left unsatisfied?
Answer:
22
Step-by-step explanation:
First, we need to find 1/8 of 176, which is basically 176/8 = 22.
22 = 1/8
154 = 7/8
So 154 customers left satisfied and 22 unsatisfied.

The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
- 4x + 3y = 12 ( add 4x to both sides )
3y = 4x + 12 ( divide the terms by 3 )
y = [tex]\frac{4}{3}[/tex] x + 4 ← in slope- intercept form
with slope m = [tex]\frac{4}{3}[/tex] and y- intercept c = 4
---------------------------------------------------
Given
- 5x + 3y = - 9 ( add 5x to both sides )
3y = 5x - 9 ( divide the terms by 3 )
y = [tex]\frac{5}{3}[/tex] x - 3 ← in slope- intercept form
with slope m = [tex]\frac{5}{3}[/tex] and y- intercept c = - 3
the market price of an article is rupees 1500 find the price after allowing the discount of 10%
Answer:
Step-by-step explanation:
1500 x .10= 150
1500 - 150 = 1350
=1350 is the price after following the discount of 10%
Answer:
1350
Step-by-step explanation:
Market price = 1500
Discount = 10%
Price of article after allowing discount = 1500 - (1500* 10/100)
=1500 - 150
= 1350

According to the line plot, what is the total amount of time spent studying by the students who studied for an hour each?
Answer:
2.5 hours
Step-by-step explanation:
The total amount of time studying by students who spent 1/2 an hour studying is the product of the number of students who spent 1/2 an hour studying by 1/2 an hour.
Hence, counting the number of dots on the point marked 1/2 gives the count of students who spent 1/2 an hour studying and multiply this number by 1/2.
Total amount of hours spent = 1/2 * 5 = 2.5 hours

What is the perimeter of the following figure?
Answer:
13.4 x 2 = 26.8
12.5
HYPOTENUSE:
10^2 + 12.5^2 = 256.25
Square root of 256.25 = around 16
which would equal 256
16 is your hypotenuse.
26.8 + 12.5 + 16 = 55.3 is your perimeter

Find the formula for the following sequence
Geometric : a7=9 and a12=2187
Step-by-step explanation:
a geometric sequence is s sequence, where every new element is generated by multiplying the previous element by the same number.
a n = a1 × number^(n-1)
so, a12/a7 = number^5
=> 2187/9 = 243 = number^5
=>
[tex]number = \sqrt[5]{243} [/tex]
=> number = 3
so, what is a1 ?
it has to satisfy e.g. a7.
9 = a1 × 3^6
9 = 3^2
=> 3^2 = a1 × 3^6
=> 1 = a1 × 3^4
=> a1 = 1/(3^4) = 1/81
therefore, the whole formula is
a n = 1/81 × 3^(n-1 )
PLEASE HELP ITS A TIMED TEST!!!
A health club charges a $25 one-time sign-up fee and a monthly membership fee of $44 per month. Find the rate of change.
Answer:
First you need to set up an equation y = mx + b. m would be the monthly charge and b would be the one time fee. x represents the number of months.
To solve for the number of months with a total price of 240 we substitute 240 in for y and solve for x.
240 = 25x + 40
subtract 40 from each side
200= 25x
divide by 25
8 = x
8 months
10 + 7r = 45
7r = 35
r = 5
5 milesStep-by-step explanation:
The rate of change is 5.
What is rate of change?The rate of change of anything is how rapidly it changes over time (ROC).
You must first create the equation
y = mx + b,
where m represents the monthly price and b represents the one-time cost. Months are represented by the number x.
We replace 240 for y and solve for x to find the total number of months at a price of 240.
40 is subtracted from either side of 240 = 25x + 40.
200 = 25x
25 divided
8 months equals 8.
10 + 7r = 45
7r = 35
r = 5
Therefore, 5 is the rate of change.

What is the effect on the graph of the function f(x) = V3x when f(x) is replaced with f(x + 4)?
Answer:Replacing x with -x will reflect a graph across the y-axis. Multiplying x by 3 before the function is applied will compress the graph horizontally. This means the correct choice is D.
What is 67,795 rounded to the nearest thousand?
Answer:
68 000
Step-by-step explanation:
When we round to the nearest thousand, we have to look which thousand is closer to the value. So in our case 67795 is 205 away from 68 000 and is 795 away from 67000. From this we know that 68 000 is closer, therefore if we round 67 795 to the nearest thousand we will get 68 000.

Answer:
-4
Step-by-step explanation:
Parallel lines are lines that run across from each other but never intersect. For this to work, they must change at the same rate and have the same slant. This means parallel lines must have equal slopes; therefore, the slope of the parallel line is -4. It is also important to note that parallel lines must have different y-intercepts, or they would just be the same line.

A student would like to estimate the proportion of students at his school who have lunch during period 4. To do so,
he selects a random sample of 40 students and finds that 30% of them have period 4 lunch. Later, he goes to the
guidance office and finds that of the 380 students at this school, 25% of them have period 4 lunch. Which of the
following properly describes the number, 25%?
sample
statistic
population
parameter
Yeah
Answer:
D
As we are getting the 25% from the whole population of 380 students, therefore this is a population proportion which is a parameter. Note that we get parameter from population and statistic from the sample.
Step-by-step explanation:
The property parameter describes the number, 25% because 25% from a population of 380 students, this is a population proportion that may be used as a metric option (D) parameter is correct.
What are population and sample?It is described as a collection of data with the same entity that is linked to a problem. The sample is a subset of the population, yet it is still a part of it.
We have:
Number of samples = 40
30% of them have period 4 lunch.
Total population = 380
25% of them have period 4 lunch.
Because we're collecting 25% from a population of 380 students, this is a population proportion that may be used as a metric.
We collect parameters from the population and statistics from the sample.
Thus, the property parameter describes the number, 25% because 25% from a population of 380 students, this is a population proportion that may be used as a metric option (D) parameter is correct.

What is length of line segment?The distance between any two points is the length of the line segment joining the points.
The formula for the distance, D, between two points whose coordinates are (x₁, y₁) and (x₂, y₂)
D = √((x2 – x1)² + (y2 – y1)²)
This is called the Distance Formula.
Given,
Coordinates of points Q (8, 2) and R (5, 7)
Length of QR = Distance between point Q and point R.
D = √((x2 – x1)² + (y2 – y1)²)
D = √((5 - 8)² + (7 - 2)²)
D = √(-3² + 5²)
D = √9 + 25
D = √34
D = 5.83 units
Length of QR rounded to one decimal = 5.8 unit

Step-by-step explanation:
The formula s = StartRoot StartFraction S A Over 6 EndFraction EndRoot gives the length of the side, s, of a cube with a surface area, SA. How much longer is the side of a cube with a surface area of 1,200 square inches than a cube with the surface area of 768 square inches? StartRoot 2 EndRoot in. 2 StartRoot 2 EndRoot in. 4 StartRoot 2 EndRoot in. 36 StartRoot 2 EndRoot in.
Answer:
2.83 inches
Step-by-step explanation:
The formula for surface area of cube = 6s²
Where
s = side length of cube
S.A = 6s²
s² = S.A/6
s = √S.A /6
For cube a
Surface area = 1200 in²
Hence,
side length = √1200/6
Side length = √200
= 14.14 inches
For cube b
Surface area = 768 in²
Hence,
side length = √768/6
Side length = √128
= 11.13 inches
How much longer is the side of a cube with a surface area of 1,200 square inches than a cube with the surface area of 768 square inches?
Therefore,
14.14 inches - 11.13 inches
= 2.83 inches
