Answer 1

The circle area formula is A=pi r^2. I am assuming those numbers represent diameter, and diameter is radius x 2. 6/2=3, and pi 3^2= 28.27433388. Divide this by 2 and the area of your half circle is 14.13716694. On the other half circle, 5/2= 2.5. pi times 2.5^2 is 19.63495408, divided by two is 9.817477042. Hope it helps!

The table shows the weekly change in the water level in a swimming pool. After 4 weeks, the pool owner adds water to return the water level back to the original level. Raising the water level by 1 inch requires 320 gallons. The water hose has a flow rate of 5.75 gallons of water per minute. Will it take less than an hour to fill the pool back to return the water level to the original level? Explain your reasoning.

Answers

so we just need to raise the pool back to original level

in total, the pool drained a total of 1 and 3/8 inches

so we need to find out how long it would take to raise the pool by 1 and 3/8 inches

1 inch=320 gallons

1 and 3/8=320 times 1 and 3/8=320 and 960/8=440

he needs to put in 440 gallons

it is 5.75 gallons per minute

find out how many minutes it will take

440=5.75 times x minutes

divide both sides by 5.75

76.521=xminutes

round

77 minutes

1 hour=60 minutes

77>60

it will take more than 1 hour to make the pool back to original level..

PLEASE HELP! I WILL GIVE BRAINLIEST!!!! (no trolls) PLEASE SHOW WORK OR GIVE EXPLANATION!!!!!!

Answers

explanation:

The fastest way to find the missing endpoint is to determine the distance from the known endpoint to the midpoint and then performing the same transformation on the midpoint. In this case, the x-coordinate moves from 4 to 2, or down by 2, so the new x-coordinate must be 2-2 = 0. The y-coordinate moves from 4 to -5, or down by 9, so the new y-coordinate must be -5-9 = -14.

An alternate solution would be to substitute (4,4) for (x1,y1) and (2,-5) for (x,y) into the midpoint formula:

x=(x1+x2)/2

y=(y1+y2)/2

Solving each equation for (x2,y2) yields the solution (0,-14).

Answer:

b = 6

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

3x + y - 8 = 0 ( subtract 3x - 8 from both sides )

y = - 3x + 8 ← in slope- intercept form

with slope m = - 3

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-3}[/tex] = [tex]\frac{1}{3}[/tex]

Consider the second line with equation

- 2x + by + 9 = 0 ← rearrange into slop- intercept form

by = 2x - 9 ( divide terms by b ( b ≠ 0 )

y = [tex]\frac{2}{b}[/tex] x - [tex]\frac{9}{b}[/tex] ← in slope- intercept form

with slope m = [tex]\frac{2}{b}[/tex]

Then

[tex]\frac{2}{b}[/tex] = [tex]\frac{1}{3}[/tex] ( cross- multiply )

b = 6

(Read end and look at attached file for correct answers) Mrs. Ibarra wants to create a right triangle for a geometry test. She plans to use 15, 36, and 41 as side lengths. Which statements should she consider to determine whether it will be a right triangle? Check all that apply. 15 + 36 greater-than 41, so the side lengths will form a triangle. 15 + 36 not-equals 41, so those lengths will not form a triangle. 15 squared + 36 squared = 1,521 41 squared = 1,681 Since a squared + b squared not-equals c squared, it will not be a right triangle. 15 squared + 36 squared = 297 41 squared = 82. The correct answers are actually A, C, D, and E. I got it wrong because people said the answer were only A and C. And of course it was on a test so I couldn't fix it. Anyway i just want to prevent from anyone else being misled. Look at the attached file.

Two dot plots are shown one below the other. The title for the top dot plot is Sixth Graders and the title for the bottom plot is Seventh Graders. Below the line for each dot plot is written Height followed by inches in parentheses. There are markings from 52 to 57 on the top line and the bottom line at intervals of one. For the top line there are 2 dots above the first mark, 1 dot above the second mark, 1 dot above the third mark and 2 dots above the fourth mark.

Jason has already used 4/12 cans of paint while painting furniture. He is painting chairs which each use 10/6 cans of paint.

What is the total number cans used if he paints 19 chairs?
Your final answer should be a decimal.

Answers

Answer:

Based off of the calculations I did, I got 32 as the answer.

Step-by-step explanation:

Jason uses 10/6 of the paint for each chair he paints and according to the question, there are 19 chairs.

So we multiply these two numbers to get the amount of paint used after painting all 19 chairs.

10/6 * 19 = 31.666...

Then we add the previous amount Jason used for painting the furniture to the total amount of paint used after painting the 19 chairs.

31.666... + 4/12 = 32.

Thus, Jason used 32 cans of paint in total.

You should be able to figure out this answer if you pay attention in class
