Answer:
C?
Step-by-step explanation:
I chose C because it depends how much money the school has. So it wouldn’t be 5 or 12, because we don’t know how much money the school has to buy how many basketballs. Tell me if I’m wrong.
Answer:
a
Step-by-step explanation:
y = 3x - 7 → (1)
4x - 5y = - 20 → (2)
substitute y = 3x - 7 into (2)
4x - 5(3x - 7) = - 20
4x - 15x + 35 = - 20
- 11x + 35 = - 20 ( subtract 35 from both sides )
- 11x = - 55 ( divide both sides by - 11 )
x = 5
substitute x = 5 into (1)
y = 3(5) - 7 = 15 - 7 = 8
solution is (5, 8 )
The circumference of a circle divided by its diameter always may be written as pi:
![\frac{c}{d}= \pi](https://tex.z-dn.net/?f=%20%5Cfrac%7Bc%7D%7Bd%7D%3D%20%5Cpi%20%20)
Pi itself is close to 3.14; keep in mind pi is an irrational number, so it may never be equal to a number written in decimal form.
Also, pi is equal to c/d, but that doesn't mean that's the way pi is defined.
Answer:
Surface area:
Step-by-step explanation:
(Imagine there's line separating the rectangle and square)
<u>Rectangle</u>
l × w × h
3 cm × 13 cm × 3 cm
117 cm^3
<u>Square</u>
l × w × h
5 cm × 2 cm × 3 cm
30 cm^3
<u>Total Area</u>
117 cm^3 × 30 cm^3
3,510 cm^3
