HOW MANY BASEBALLS CAN FIT INTO THE TRACTOR TRAILER. THE TRAILER DIMENSIONS ARE 301.5"L X 96.99"W X 105.04"H AND CIRCUMFERENCE R

Shkiper50 [21]

Volume of tractor = length x width x height = 301.5 x 96.99 x 105.04 = 3,071,630.624

For baseballs of 9 inches:
$9=2\pi r \\ \\ r= \frac{9}{2\pi}$

Volume = $\frac{4}{3} \pi r^3= \frac{4}{3} \pi \left( \frac{9}{2\pi} \right)^3=12.31$

Number of 9 inches baseballs = $\frac{3,071,630.624}{12.31} = 249,513$

For baseballs of 9.25 inches:
$9.25=2\pi r \\ \\ r= \frac{9.25}{2\pi}$

Volume = $\frac{4}{3} \pi r^3= \frac{4}{3} \pi \left( \frac{9.25}{2\pi} \right)^3=13.37$

Number of 9.25 inches baseballs = $\frac{3,071,630.624}{13.36} = 229,824$

Therefore, the tractor can contain between 229,824 and 249,513 baseballs.

Sharon wants to start a savings account with the money she earns selling scented candles. She already has $50 and would like to

Romashka [77]

Answer:

She must sell as least 20 candles

Step-by-step explanation:

Sharon has 50 dollars

She makes 2 dollars per candle

Money in 50+2c

She needs at least 90

90≤ 50+2c

We need to solve this inequality

Subtract 50 from each side

90-50≤ 50-50+2c

40 ≤ 2c

Divide by 2

40/2 ≤ 2c/2

20 ≤ c

She must sell as least 20 candles

To solve the equation w/8 - 4 = 20, you would first add 4 to each side and then divide each side by 8.

bearhunter [10]

False because, you DO add 4 to the sides but you would multiply the 8 because you to the opposite to cancel it out
