Jan spent the day at the mall. She came home with $9.50. She spent $5.25 on earrings and 3 times that amount on a shirt. How muc

ki77a [65]

Answer:

She took $30.50 to the mall originally

Step-by-step explanation:

Let us solve the problem step by step

∵ She spent $5.25 on earrings

∵ The price of the shirt is 3 times the price of the earrings

∴ The price of the shirt = 3 × 5.25 = 15.75

∴ She spent $15.75 on the shirt

Find her total spending in the mall by adding the prices of earrings and the shirt

∴ She spent = 5.25 + 15.75 = 21

∴ She spent $21 on the mall

∵ She came home with $9.50

∵ She spent $21 on the mall

- Add them to find her original amount of money

∴ She took = 21 + 9.50 = 30.50

∴ She took $30.50 to the mall originally

A farmer wants to build a new grain silo. The shape of the silo is to be a cylinder with a hemisphere on the top, where the radi

notsponge [240]

Answer:

The radius of the silo should be $16\ ft$

Step-by-step explanation:

we know that

The volume of the grain silo is equal to the volume of the cylinder plus the volume of a hemisphere

$V=\pi r^{2} h+\frac{4}{6}\pi r^{3}$

we have

$V=35,500\pi\ ft^{3}$

$h=4D=8r$

substitute the values and solve for r

$35,500\pi=\pi r^{2} (8r)+\frac{4}{6}\pi r^{3}$

Simplify

$35,500=r^{2} (8r)+\frac{4}{6}r^{3}$

$35,500=8r^{3}+\frac{2}{3}r^{3}$

$35,500=\frac{26}{3}r^{3}$

$r^{3}=35,500*(3)/26$

$r=16\ ft$
