Apolline is mowing lawns for a summer job. For every mowing job, she charges an initial fee plus a constant fee for each hour of

OLEGan [10]

Answer:

Base Fee = $7

Extra charges = $7

Step-by-step explanation:

Represent the base charge with x and the additiional charges with y.

For the 5 hours job, we have:

$42 = x + 5y$

For the 3 hour job

$28 = x + 3y$

Solving for x and y;

$42 = x + 5y$

$28 = x + 3y$

Subtract the second equation from the first

$42 - 28 = x - x + 5y - 3y$

$14 = 2y$

Solve for y

$y = 14/2$

$y = 7$

Substitute 7 for y n the first equation

$42 = x + 5y$

$42 = x + 5 * 7$

$42 = x + 35$

$x = 42 - 35$

$x = 7$

A snow cone is a tasty treat with flavored ice and a spherical bubble gum ball at the bottom. The radius of the cone is 1.25 inc

noname [10]

Volume of the cone=1/3πr^2h
V=1/3π(1.25)^2×2.75
V≈4.5 cubic inches

Volume of the sphere=4/3πr^3
V≈0.07 cubic inches

4.5-0.07=4.43. As a result, the volume of the cone that can fipp with ice is about 4.43 cubic inches. Hope it help!
