Plssss help me my test is due is 30 minutes.



The graph below shows the height of a ball versus time for one bounce. For how
many seconds was teh ball at a height of 7 feet or more above ground?

Answer:

[tex]s = (3 \times 4)2 = 24 \\ s =(3 \times 5)2 = 30 \\ s = (4 \times 5)2 = 40 \\ \\ 24 + 30 + 40 = 94[/tex]

Answer:

Line k

Step-by-step explanation:

The slope is found by rise/run which is change in y/change in x. If you look at a certain few points on line k, you will see it is 3/1 which is 3. The line is going downwards so it is -3.

Answer:

line k

Step-by-step explanation:

Hey There!

So immediately we notice that the slope is negative so we can eliminate line m and line n

So its between line k and j

we notice that it says -3

so the rise over run has to be down 3 over 1

line k shows exactly this

therefore line k is your answer :)

Answer:

9

Step-by-step explanation:

Hello There!

The image shown is a trapezoid

The dimensions of the non shaded area are:

Base 1 = 2 units

Base 2 = 4 units

Height = 3 units

Now that we have found the dimensions we want to solve for the area by using the area formula for a trapezoid

[tex]A=\frac{a+b}{2}h[/tex] where a and b are bases and h is the height

knowing the dimensions all we have to do is plug in the values

so

[tex]A=\frac{2+4}{2} 3\\2+4=6\\\frac{6}{2} =3\\3*3=9\\A=9[/tex]

so we can conclude that the area of the non shaded part is 9 square units

its easy but let me explain

Step-by-step explanation:

If she earns $8.15 an hour and she works for 4 1/2 hours.

You multiply

$8.15 x 4.5 = n

n= $36.675    But your not done yet, ROUND TO HUNDREDTHS PLACE!!!

if there is a number 5 or higher next to the hundredths place then you bump the number up by 1

she would of earned $36.68 in 4.5 hours  Glad to help

Answer:

Question 2: A. Overlapping lines.

The equations are identical; and if we would treble the first equation, we get the second equation.

Question 3: B. Multiply the second equation by -3 to get [tex]-3x - 12y = -48[/tex]

Answer:

The length of a side of the square will b 2/5 cm.

Step-by-step explanation:

To find the area of a 2d object, you need to multiply length and width together. Since it's a square, all the sides are the same length, so that makes it easier. We need to find the square root of 4 and 25. [tex]\sqrt{4}[/tex] is 2, and [tex]\sqrt{25}[/tex] is 5.

Now we need to multiply 2/5 by itself to check. 2/5 x 2/5 = 0.16, or 4/25. The answer is correct. The final result is 2/5. Hope this helped!! :]

The area of a square is the square of one of its side lengths. The length of a side of the square is 2/5 cm

Given:

[tex]Area = \frac{4}{25}cm^2[/tex]

Shape: Square

The area of a square is:

[tex]Area = Length^2[/tex]

So, we have:

[tex]Length^2 = \frac 4{25}cm^2[/tex]

Take positive square roots of both sides

[tex]Length = \sqrt{\frac 4{25}cm^2}[/tex]

[tex]Length = \frac 2{5}cm[/tex]

Hence, the length of the square where the area is [tex]\frac 4{25}cm^2[/tex] is [tex]\frac 2{5}cm[/tex]

Answer:

b= −3 /50 f+ 27/ 50

f= −50 /3 b+9

Step-by-step explanation:

Let's solve for b.

50b+3f=27

Step 1: Add -3f to both sides.

50b+3f+−3f=27+−3f

50b=−3f+27

Step 2: Divide both sides by 50.

50b /50 = −3f+27 /50 b= −3 /50 f+ 27 /50

Let's solve for f.

50b+3f=27

Step 1: Add -50b to both sides.

50b+3f+−50b=27+−50b

3f=−50b+27

Step 2: Divide both sides by 3.

3f /3 = −50b+27 /3

f= −50 /3 b+9

Step-by-step explanation:

100 divided by 22 = 4.54545454545 (since the total amount is 22)

8*4.54545454545 = 36.3636363636 (since 8 people out of 22 finished)

Answer: 28.8 ounces of red paint

Step-by-step explanation:

The total amount of paint created the first time Mango mixed colors was:

= 24 + 16

= 40 ounces of purple color

For 40 ounces of purple, 16 ounces of red was needed. Proportion is therefore:

= 16/40

If one wants 72 ounces of purple therefore:

= Proportion of red used * 72 ounces

= 16/40 * 72

= 28.8 ounces of red paint
