You can complete 40 pushups in 2 minutes. Your friend can complete 57 pushups in 3 minutes. Do these rates form a proportion? Explain
Answer:
No.
Step-by-step explanation:
In order to find the answer, you have to make the rates as simple as they get: In other words, you have to make it so that the rate has one on each side. Like this:
40:2
20:1
57:3
19:1
As you can see, they don't have the same numbers once their simplified. Which means that they can't be proportional. So, In this specific problem, you can do one more pushup in one minute than your friend can do.
Have a good day and good luck!

IM STRUGGLING SO BAD HELP ;-; Find the area of the shaded region. Use 3.14 for n.
2 yd
2 yd
3 yd
6 yd
-8 yd —
sydd syd
Syd →
Answer:
57.74 yd²
Step-by-step explanation:
First, find the area of the "rectangle" as if there weren't different figure cut out of it:
(5+6+5)8
16(8)
128 yd²
Next, we are going to find the area of the four figures that are cut out from the rectangle. The circle at the bottom, the rectangle at the top, and the triangles on each side.
The first shape we can tackle will be the circle. The formula for finding the area of a circle is πr² or in this case 3.14r². The diameter of the circle is 6 yards, and half of the diameter is equal to the radius which gives us 3 yards as the length. Now simplify the expression:
3.14(3)²
3.14(9)
28.26 yd² is the area of the circle.
Next, we're going to find the area of the rectangle at the top. It's dimensions are 6 yards by 3 yards, which gives us an easy 18 yards² as the area (lxw).
Now we're going to solve for the area of the triangles. By the looks of the general dimensions of this shape, I am assuming these triangles are congruent to each other, which means we will only have to solve for its area once. To find the area of a triangle we have to use the expression: (lxw)/2. However, we don't know one of those dimensions. We know that the length is 8 yards as shown in the diagram, and by using the widths 2 yards and 5 yards, and their relation to the triangle, we can deduce the width is 3 yards. Now we have values necessary to simplify the expression:
(8x3)/2
24/2
12 yards² is the area of one triangle.
Because I stated previously that the triangles are congruent, they both have an area of 12 yards. Now we add the areas of each of the four figures, and subtract them from the area of our large rectangle:
128-(12+12+28.26+18)
128-70.26
57.74 yd² is the area of the shaded region

<1 and <2 are complementary angles. The measure of <1 is 60 degrees. The measure of <2 is 3x. Find the value of x.
Answer:
X=10
Step-by-step explanation:
The measure of the two angles added up is 90 degrees, since it’s a right angle (we know it’s a right angle because of the red square in the corner). You know that <1 is 60, so <2 has to be 30 because the two angles have to add up to 90 degrees. Since <2 is 3x, you have to find a number times 3 that equals 30.
x=10.
To check the answer, 10 * 3 is 30 and 30+60=90 (the total measure of a right angle), so it’s correct.
A waitress earned $9 per hour at her job plus an additional $75 in tips on Friday. She earned more than $150 total. Which inequality best represents the situation, where h represents the number of hours she worked on Friday? *
A. 9 + 75h > 150
B. 9 + 75h ≥ 150
C. 9h + 75 > 150
D. 9h + 75 ≥ 150
Answer:
the answer is c :)
Step-by-step explanation:
Answer:
C. 9h + 75 > 150Step-by-step explanation:
One part is that it says that she makes more than, not more than or equal too 150. Which cuts the options down to two.
A. and C.
The second thing that the text says is that she makes 9 dollars and hour, not 75 an hour. Which means that A. can't be the answer.
Thus, C. is the correct answer.
Have a good day and good luck!

A coin is flipped twice. What is the probability that the coin will land on tails on the first flip and will land on tails again on the second flip?
Question 5 options:
1/4 =0.25=20%
1/4 =0.20=25%
1/2 =0.25=25%
1/4 =0.25=25%
Answer:
1/4=0.25=25%
Step-by-step explanation:
A coin has two sides, heads and tails, and if you take 100% divided by two you get 50, you want to know what is the probability it will land on tails TWICE so divide 50 by two and you get 25.
1/2=50
1/4=25
0.25 x 100= 25%

The foundation for a new building at the high school is rectangular in shape. The area of the foundation is 5x^3 + 4x^2 - 10x - 8 square meters. If the width equals (x^2 - 2) meters. What is the length of the rectangular foundation?
We should divide x^2-2 from the equation.
I will spare you from the boring steps of equation dividing.
Now getting 5x+4
Just do this like you are doing long division but instead using variables, be careful there is no x term in the second expression so you have to give it an empty space :)

Answer:
-m²+81
Step-by-step explanation:
Hello There!
9x-m=-9m
9x9=81
mx-m=-m²
9xm=9m
9m-9m=0
we would be left with
-m²+81
Answer:
81 - m²
Step-by-step explanation:
Use (a + b)(a - b) = a² - b² identity
(9 + m)(-m + 9) = (9 + m)(9 - m)
= 9² - m²
= 81 - m²

A ball is thrown from an initial height of 6 feet with an initial upward velocity of 17 ft/s. The ball's height h (in feet) after t seconds is given by the following.
h=6+17t-16t^2
Find all values of t for which the ball's height is 10 feet.
Round your answer(s) to the nearest hundredth.
(If there is more than one answer, use the "or" button.)
t=___seconds
Answer:
32
Explanation:
6 + 29t - 16t^2 = 18. 16t^2 - 29t + 12 = 0. t = (29 +- √(29^2 - 4*12*16))/32.

Solve the inequality and graph its solution...
2x+4≥24
The solution of the inequality 2x+4≥24 is x≥10.
What is Inequality?A relationship between two expressions or values that are not equal to each other is called 'inequality.
The given inequality is 2x+4≥24
Two times of x plus four greater than or equal to twenty four.
Subtract 4 from both the sides
2x≥24-4
2x≥20
Divide both sides by 2
x≥10
Hence, the solution of the inequality 2x+4≥24 is x≥10.

Trish is ordering t-shirts from a website that charges a certain amount per t-shirt plus a flat rate for shipping. The cost for a given number of t-shirts is shown in the table.
20a. Write an equation to represent the situation. (Write your answer with no spaces, all lowercase letters, and write the slope as a decimal)
20b. What does the slope mean in the context of the situation?
20c. What does the y-intercept mean in the context of the situation?
Answer:
Hope this helps
Step-by-step explanation:
T means amount of t shirts they are buying
5.99 is amount of shipping cost
first do 32.24-5.99=26.25
then do 26.25/3=8.75
so 8.75= cost of shirt
20a. (8.75*T)+5.99
20b.(I might get this part wrong just let me know)
M=Y2-Y1/X2-X1
so 32.24-5.99/3-0= 26.25/3 Or 8.75
20c=Y=Mx+B
3=8.75(32.24)+b=-279.1
