Answer: $19

Step-by-step explanation: We know Giana earned $10 for shoveling. We know she makes $2 for every inch of snow on the ground. She shoveled 4.5 inches.

To find how much money she got from shoveling 4.5 inches, simply multiply $2 by 4.5

$2.00 x 4.5 = $9 from shoveling 4.5 inches of snow.

Now add $9 to the initial value of $10

$10 + $9 = $19 earned in total.

Which expression could be used to determine the cost of a $40 video game after a 15 percent discount?
LUCKY_DIMON [66]

Answer: The required expression is,

$ 40(0.85)

Step-by-step explanation:

Given,

The original cost of the videogame = $ 40,

Discount percentage = 15%,

So, the amount of discount = 15% of 40

= (0.15)40                     ( ∵ 1% = 0.01 )

Hence, the cost of the videogame = original cost - discount

= 40 - (0.15)40

= 40 (1-0.15)

= 40(0.85)

Which is the required expression .

Vadim26 [7]

Answer:

∠ O = 72°

Step-by-step explanation:

the inscribed angle R is half the measure of its intercepted arc NQ , then

arc NQ = 2 × 36° = 72°

the central angle O is equal to the measure of the arc that subtends it , so

∠ O = arc NQ = 72°
