Answer:

98.83

Step-by-step explanation:

We set up the equation $\frac{37}{360} *\pi 17.5^2$ , where 17.5 is the radius, and 37/360 is the ratio of the slice of pie. When we solve that equation we get about 98.83, which will be our answer.

Answer:

98.83

Step-by-step explanation:

Since 37° is 37/360th of the full circle, the area of the size of pie will be 37/360th of the full area. The radius is d / 2 = 17.5 so the area is:

37/360 * πr²

= 37/360 * 3.14 * 17.5²

= 98.83

At the movie theater, child admission is $5.10 and adult admission is $8.70 on Sunday, 138 tickets were sold for a total sales o

kiruha [24]

C + a = 138.....c = 138 - a
5.10c + 8.70a = 995.40

5.10(138 - a) + 8.70a = 995.40
703.80 - 5.10a + 8.70a = 995.40
-5.10a + 8.70a = 995.40 - 703.80
3.60a = 291.60
a = 291.60/3.60
a = 81 <===

It takes Kay 20 minutes to drive to work traveiling 45 mph. Two minutes after she left home this morning, her husband, Dan, star

BARSIC [14]

Answer:

Kay's husband drove at a speed of 50 mph

Step-by-step explanation:

This is a problem of simple motion.

First of all we must calculate how far Kay traveled to her job, and then estimate the speed with which her husband traveled later.

d=vt

v=45 mph

t= 20 minutes/60 min/hour = 0.333 h (to be consistent with the units)

d= 45mph*0.333h= 15 miles

If Kay took 20 minutes to get to work and her husband left home two minutes after her and they both arrived at the same time, it means he took 18 minutes to travel the same distance.

To calculate the speed with which Kate's husband made the tour, we will use the same initial formula and isolate the value of "V"

d=vt; so

v= $\frac{d}{t}$
