Answer:

yes

Step-by-step explanation:

8 × 90 = 720

4 × 180 (half of 8, double of 90) = 720

2 × 360 (half of 4, double of 180) = 720

1 × 720 = 720

- If you divide a number by four and then add six, you<br> get eighteen. What is the number?

stiks02 [169]

Answer:

48

Step-by-step explanation:

Create an equation to represent this, where x is the unknown number.

$\frac{x}{4}$ + 6 = 18

Solve for x, by first subtracting 6 from both sides:

$\frac{x}{4}$ = 12

Multiply each side by 4:

x = 48

So, the number is 48

balu736 [363]

Atticus will spend $1.60 on wrapping paper.

Step-by-step explanation:

Given,

Cost of paper per yard = $2.40

Atticus wants to buy = 2/3

Cost of 2/3 yards of paper = $\frac{2}{3}*2.40$

Cost of 2/3 yards of paper = $\frac{4.80}{3}$

Cost of 2/3 yards of paper = $1.60

Atticus will spend $1.60 on wrapping paper.

A cannon ball is launched at 6 feet per second from the top of a platform 12 feet above the ground.

AleksAgata [21]

A.) y = ut - 1/2gt^2 + 12
y = 6t - 1/2(9.8)t^2 + 12
y = 6t - 4.9t^2 + 12

b.) The y-intercept is 12

c.) The y-intercept represent the height of the ball at time t = 0

d.) At the time the ball reaches the ground, y = 0
-4.9t^2 + 6t + 12 = 0
t = 2.29 seconds
Therefore, it took the ball 2.29 seconds to reach the ground.
