S = 60W + 650 <== ur equation
after 18 weeks...so sub in 18 for W
S = 60(18) + 650
S = 1080 + 650
S = 1730 <==
Answer:
y=10
Step-by-step explanation:
There are 13 diamonds in a regular deck of cards.
So the probability of picking a diamond card is 13/52.
The area is 795.5 sq units.
We first find the apothem, using the formula:

Since there are 100 sides, all sides are equal and the perimeter is 100, the side length, s, is 1:

Now we find the area of the polygon. Since there are 100 sides, there will be 100 equal triangles using the center as a vertex. The formula for the area of a triangle is A=1/2bh; in this case, b is s, the side length, and h is a, the apothem. This gives us:
A=100(1/2)(s)(a) = 100(1/2)(1)(15.91) = 795.5.
Answer:
31.4
Step-by-step explanation:
Circumference = pi x diameter.
Diameter = 2 x radius
Radius = 5
Diameter = 10
Circumference = 10 x pi = 31.4
