frutty [35]

Answer:

Ball cannot be fit inside the box.

Step-by-step explanation:

Given:

Circumference of ball = 26 inches

Dimension of box = 8.25 in x 8.25 in x 8.5 in.

We need to find the whether ball gets fits inside the box.

First we will find the Diameter of ball.

Circumference of ball is given so we will find radius of the ball.

Circumference of the sphere is equal to 2 times π times radius.

framing in equation form we get;

2\pi \times r =26\\\\r= \frac{26}{2\pi}= 4.14\ in.

Now we will find the Diameter of the ball.

Diameter of ball is equal to 2 times radius.

framing in equation form we get;

Diameter of ball =  2\times 4.14 = 8.28\ in

Now given that two parallel sides of box has dimension which is 8.25 in.

Since Dimension of box is smaller than diameter of the ball.

Hence we can say that ball cannot be fit inside the box.

At the last Chance Filling Station, gas costs $1.60 a gallon. Trevor paid $32.00 to fill his tank. How many gallons of gas did h
lapo4ka [179]

Answer:


Step-by-step explanation:

y = total cost of gas

x = gallons of gas

(a)

y = 1.60x

(b)

y = 1.60x

32.00 = 1.60x

32.00 / 1.60 =  1.60x / 1.60

32.00 / 1.60 =  x

20 = x

x = 20

Trevor bought 20 gallons of gas.
