Answer:

(- 7, - 5 )

Step-by-step explanation:

Under a counterclockwise rotation about the origin of 180°

a point (x, y ) → (- x, - y ), thus

(7, 5 ) → (- 7, - 5 )

What is the volume of a volleyball with a diameter of 8 inches
natita [175]

Hello there!

We are going to follow the volume of a sphere since a volleyball is a sphere. V=4/3πr^3 is the formula for finding the volume of a sphere. The only unknown value is r, or the radius. We find the radius by halving the diameter.

8/2 = 4, so we have a radius of 4 inches.

Place the value of 4 in for r - V = 4/3 x π x (4)^3

Now solve.

V = 4/3 x π x (4)^3

Start by squaring 4.

V = 4/3 x π x 64

Next, multiply 4/3 by 64. (<em>you can do it in any order since there are no parenthesis</em>)

V = π x 85.33

Lastly, multiply 85.33 by pi.

V = 268.08

So, your answer is approximately 268.08, since we used rounding it is not exact. I hope this was helpful and have a great rest of your day! :)

If a 12-student class averaged 90 on a test, and a 20-student class averaged 80 on the test, then all 32 students averaged
Alexxx [7]
Let the marks of the students in class 1 be

m_1, m_2, ....., m_1_2

the average of these 12 marks is 90, so 

\frac{m_1+ m_2+ .....+ m_1_2}{12}=90

which means

m_1+ m_2+ .....+ m_1_2=90*12=1080


similarly, let n_1, n_2, ....., n_2_0 be the marks of the students in the second class, 

so \frac{n_1+ n_2+ ..... n_2_0}{20}=80

which means n_1+ n_2+ ..... n_2_0=80*20=1600


The 32 students averaged:

\frac{(m_1+ m_2+ .....+ m_1_2)+(n_1+ n_2+ ..... n_2_0)}{12+20}= \frac{1080+1600}{32}= \frac{2680}{32}=   83.75
