What is -0.6(r+0.2) = 1.8 ???

lana66690 [7]

Answer:

r = -3.2

Step-by-step explanation:

-0.6(r+0.2) = 1.8

Divide by -.6

-0.6/-.6(r+0.2) = 1.8/-.6

r+.2 = -3

Subtract .2 from each side

r+.2-.2 = -3-.2

r = -3.2

The fare for an Uber is $5 per trip plus $0.50 per mile. The fare for the trip from the airport to the school center was $11.50.

Vinvika [58]

Answer:

13 miles

Step-by-step explanation:

The fare for the Uber

Cost= 5+ .5 m

where m is the number of miles

We spent 11.50

11.50 = 5 + .5 m

Subtract 5 from each side

11.5 -5 = 5+.5m -5

6.50 = .5 m

Divide by .5 on each side

6.5/.5 = .5m/.5

13 = m

We went 13 miles

Answer:

$A_s=179 \ yd$

Step-by-step explanation:

Area of Circle can be calculated using following formula

$A=\pi r^{2}$

Where r is radius of circle

<u>Area of outer circle (r=11 yd)</u>

$A_1=\pi (11)^{2}\\A_1=379.94 \ yd$

<u>Area of inner circle (r=8 yd)</u>

$A_2=\pi (8)^{2}\\A_2=200.96 \ yd$

Area of shaded region

$A_s=A_1-A_2$

$A_s=379.94-200.96\\A_s=179 \ yd$
