The earth has a diameter of 7917.5 mi. What is the arc length of half the earth?
Serhud [2]

Answer:

Arc length is 12436.8m

Step-by-step explanation:

arc length  = \frac{M degree}{360degree} * πD

where M is the angle measure of the arc

and D is the diameter

considering the earth as a circle and half the earth as a semi circle the angle measure of the arc will be = 180 degrees

\frac{180}{360} * π * 7917.5 = 12436.8m

The area of a rectangle is 30 + 12x. List at least 3 possibilities for the length and width of the rectangle.
Gala2k [10]

Answer:

Below in bold.

Step-by-step explanation:

Area  = 30 + 12x and area is also = to width * length so we need to look for factors of 30 + 12x.

30 + 12x = 6(5 + 2x)

So  6 and 5 + 2x  is one possible answer.

3 and 10 + 4x is another.

12 and 2.5 + x is another.

If we multiply these pairs together we see that the result is

30 + 12x in each case.

Solve the proportion/percent problem:
Shtirlitz [24]

The change that Angie will receive from an $100 bill is $38.944.

<h3>How to calculate the value?</h3>

Angie went to the store and bought 3 pairs of tennis shoes that each cost $24. The total cost will be:

= 3 × $24 = $72

Sales tax was then calculated at 6%. This will be:

= 6% × $72

= $4.32

Total cost = Cost + Tax

= $72 + $4.32

= $76.32

Coupon off = 20% × $76.32 = $15.264

Total amount paid = Cost - Coupon

= $76.32 - $15.264

= $61.056

The change gotten will be:

= $100 - $61.056

= $38.944

Use the order operations<br><br><br> 27+6(2X2-1) 4x2-5
Andrei [34K]
27+6(2*2-1)4*2-5
2*2=4
27+6(4-1)4*2-5
4-1=3
27+6(3)4*2-5
6*3=18
27+(18)4*2-5
18*4=72
27+(72)*2-5
72*2=144
27+(144)-5
27+144+171
171-5=166

So the answer is 166.
