Answer:

15.7 cm

Step-by-step explanation:

Angle AD = 180°- 66.4°= 113.6° (considering 2x90°=180° on opposite side)

P= 2*3.14*7.9=49.6 cm

Arc AD= 49.6*113.6°/360°= 15.7 cm

George had $1,201.87 in taxable income for the last pay period. If the federal income tax rate was 15%, how much did George pay
Hatshy [7]
Just multiply the income by .15

1201.87 * .15 = 180.28

He paid $180.28

It could be a trick question though because he didnt have a lot of income so maybe he didn't pay any taxes.. I've heard that's a thing

At top cruising speed, a mako shark can swim 4 kilometers in 1/10 hour. A blue
katovenus [111]

Answer:

Step-by-step explanation:\

A mako shark can swim 4 kilometers in 1/10 hour.

Speed = Distance/Time

= 4/(1/10)

= 40km/hour

A blue whale can swim 5 kilometers in 1/4 an hour.

This shows that the Mako shark is faster as it swims at rate of 40km/hour and the blue whale swims at 20km/hour. It's faster by 20km.

= 40km - 20km

= 20km
