An Olympic swimming pool measures 164 feet long, 82 feet wide, and 9.8 feet deep. It takes approximately 7.48 gallons of water to fill 1
cubic foot of the pool. Approximately how many gallons of water are needed to fill the swimming pool?

A. 985,792 gallons
B. 10,983 gallons
C. 17,619 gallons
D. 1,913 gallons

Answers

Answer:

A

Step-by-step explanation:

Area = length times height times width

Area = 164 x 82 x 9.8

= 131790.4

Multiply by 7.48 since it takes 7.48 gallons to fill a cubic foot then you find the answer of A.

the answer is a 985,792

(I think)
1) True, -5 is left to 3 on a number line, therefore it is less than 3.
2) False, 3 is right to -5 on a number line, therefore it is greater than -5.
3) False, |-5| is equal to 5 and 5 is right to 3 on a number line, therefore |-5| is greater than 3.
4) True, |-5| is equal to 5 and 5 is right to 3 on a number line, therefore |-5| is greater than 3.

A cylinder with a radius of 5 feet and height of 2 feet.

What is the surface area of a cylinder with a radius of 5 ft and a height of 2 ft?
60Pi ft2
70Pi ft2
96Pi ft2
150Pi ft2

Answers

Answer:

B, 70pi ft2

Step-by-step explanation:

The equation to find surface area of a cylinder is 2(pi)(r)(h)+2(pi)(r)^2. So now plug the numbers in.. 2(pi)(5)(2)+2(pi)(5)^2 now, simplify. 20pi+50pi= 70pi ft2.

the correct answer is 70Pi ft2

using this formula: A=2πrh+2πr2, substitute r for 5 and h for 2 and put it like this:

a = 2π x 5 x 2 + 2π x 5 squared

2 x 5 x 2 = 20

a = 20π + 2π x 5 squared

5 squared = 25

a = 20π + 2π x 25

multiply 2 by 25 which equals 50

a = 20π + 50π

add 20 and 50 which gives you 70 making the final answer: a = 70π ft 2

Below is the graph of equation y=-lx-2l+2. Use this graph to find all values of x such that

a. y>0
b.y<0
c. y=0

THIS IS AN RSM promblem Please Help

Answers

The graph is a linear function defined by several pairs of coordinates, and the computation for x and y values is as follows.

Graph equation

y=−|x−2|+2

When x=0

then

y=−|0−2|+2

y=−|−2|+2

y=−2+2

y=0

When x=1

then

y=−|1−2|+2

y=−|−1|+2

y=−1+2

y=1

When x=2

then

y=−|2−2|+2

y=−|0|+2

y=−0+2

y=2

When x=3

then

y=−|3−2|+2

y=−|1|+2

y=−1+2

y=1

When x=4

then

y=−|4−2|+2

y=−|2|+2

y=−2+2

y=0

When x=5

then

y=−|5−2|+2

y=−|3|+2

y=−3+2

y=-1

Hence, the value of (x, y) are as follows

y=0 x=0

y=1 x=1

y=2 x=2

y=1 x=3

y=0 x=4

y=-1 x=5

If x < 0 and y < 0, where is the point (x, y) located?

Answers

Answer:

Step-by-step explanation:

You could do negative numbers because no positive number is less than 0, as you know.

So, it would have to be a negative one because they are to the left of zero on a number line, meaning less than. A positive number on a number line is usually to the right of zero, meaning more than.

For instance, x could equal -1 and y could equal -4.

It would be in Quadrant 3.

A study shows that as the temperature decreases, the electric bill increases. Which graph best represents this situation?

Answers

Answer:

The only graph whose line is strait

Step-by-step explanation:

This graph represents the situation because energy bills will have a set amount of money which directly correlates with the amount of energy you use. When it gets cold you use more energy to keep you warm. As you use more energy your price rises at the same pace-thus a strait line.

Jeff drew a line through (0, 0) and (7, 7) and said it was the line of best fit for the data.

Part A: Explain why Jeff's line is NOT the best fit.
Part B: What would be a better line of best fit for the scatter plot?
Part C: How does the actual line of best fit compare with Jeff's line?

Answers

Answer:

The line of best fit would not be right because there would be a big gap of space. The line should be the cooardinate 7,3 as this covers the line and the cooardinate 7,7 is an outlier. The new line is more accurately placed

Step-by-step explanation:

Answer:

The actual line of best fit would be from (0, 0) to (7, 4), this is because it covers majority of the points. All the other points are just anomalies. Moreover, Jeff's line is NOT the line of best fit because it is not accurate and is out of place. Furthermore, the actualy line of best fit is 3 places lower on the y-axis then Jeff's line of best fit.
