Harold has $20.00 to spend. He decided to buy a shirt for $15.95 and spend the rest on packs of gum. If each pack of gum costs $
KIM [24]

Answer:

2 or less packs

Step-by-step explanation:

15.99 + 1.99g < 20.00  where g is the number of packs of gum

Subtract 15.99 from each side

15.99 + 1.99g - 15.99 < 20.00-15.99

1.99g < 4.01

Divide by 1.99

1.99g/1.99 < 4.01/1.99

g < 2.015075377

Harold must buy whole packs so g =2 or less

A circle with radius of \greenD{3\,\text{cm}}3cmstart color #1fab54, 3, start text, c, m, end text, end color #1fab54 sits insid
Zolol [24]

Answer:

The area of the shaded region is 125.664 square centimetre

Step-by-step explanation:

Area of the shaded region  =  area of the circle with radius 7 cm - area of the circle with  radius 3 cm----------------(1)

<u>Step 1:  Finding the area of the circle with radius 7 cm</u>

Area of the circle A = \pi r^2

On substituting the value of the radius, we get

Area of the circle A =\pi(7)^2

Area of the circle A = 49 \pi square centimetre----------------(2)

<u>Step 2:  Finding the area of the circle with radius 3 cm</u>

Area of the circle a = \pi r^2

On substituting the value of the radius, we get

Area of the circle a  = \pi (3)^2

Area of the circle a  = 9 \pi square centimetre ----------------(3)

<u>Step 3:  Finding the area of the shaded region</u>

Area of the shaded region  = 49 \pi - 9\pi

= 40 \pi

= 125.664 square centimetre
