The answer would be 78 and 80 because it between those two numbers
See attached graphic.
area = .5 * side1 * sine (included angle) * side2
area = .5 * 433 * sine (37 degrees) * 520
area = .5 * 433 * 0.60182 * 520
area =

The right answer for the question that is being asked and shown above is that: "A. $30." Cho's bike was on sale for $20 less than the original price, and her total cost was half of what Jeff paid. Jeff pay A. $30 <span>for his bike</span>
Jeff = x (original price)
Cho = x-20
Answer:
x can be 4.99 to make y>0
Step-by-step explanation:
y= −1.5x + 7.5
For what value(s) of x is: y>0
lets solve for x first:
-1.5x + 7.5 = 0
-1.5x * 10 + 7.5 * 10 = 0 * 10
-15x + 75 = 0
-15x + 75 - 75 = 0 - 75
-15x = -75
x = -75/-15
x = 5
to make y>0, we substitute x<5 into the formula
y > −1.5(4.99) + 7.5
y > 0.15
therefore, x can be 4.99 to make y>0
since its 2 half circles calculate are for a circle would be area = piR^2
the diameter is 100 feet so radius would be 100/2 = 50 feet
using 3.14 for pi you get 50^2 x 3.14 = 7850 square feet for the circle area
rectangle area = l x w = 100 x 212 = 21200
now add them
21200 + 7850 = 29050 square feet
