I think the correct answer would be, I did 42 minutes + 18 minutes. So it took Marty 60 minutes to read his book and correct his report.

Hope this helped! ;)

Answer:

Option A. 4 radians

Step-by-step explanation:

step 1

Find the circumference of the circle

The circumference is equal to

$C=2\pi r$

we have

$r=5\ cm$

substitute

$C=2\pi (5)$

$C=10\pi\ cm$

step 2

Find the measure of angle $\theta$

we know that

The circumference of the circle subtends a central angle of 2π radians

using proportion

Find out the central angle by an arc length of 20 cm

$\frac{10\pi}{2\pi}=\frac{20}{x}\\\\x=2\pi (20)/10\pi\\\\x=4\ radians$

Customers of a phone company can choose between two service plans for long distance calls. The first plan has a $24 monthly fee

JulsSmile [24]

Answer:

600 minutes

Step-by-step explanation:

If we write both situations as an equation, we get:

y1 = 24 + 0.15x

y1 : total cost paid in first plan

x : total minutes of calls

y2 = 0.19x

y2 : total cost in second plan

x: total minutes of call

We are now looking for the situation where the total cost in the two plans is equal, so

y1 = y2

this gives

24 + 0.15x = 0.19x

<=> 0.04x = 24

<=> x = 600
