Answer:
A: Diane earns 200 + (10×20)= 400
B: Darryl earns (400-250)/20= $7.50 per hour
The formula for the volume of a cone is (1/3)*area of the base * height.
The base is a circle, whose area is pi times radius^2. Here this is pi *
(r^2) = 3.14*(72 / 2 yd)^2 = 4069.44 yd^2. And so the volume is (1/3) *
4069.44 yd^2 * 24yd = 32,555.52 yd^3. I recommend that you find the
most common formulas of the geometrical figures and make a flashcard
that you can use at any moment.
4 + 5 = 9
£180 / 9 = £20
£20 x 4 = £80
£20 x 5 =£100
Answer:
£80 : £100
hope it helped :)
Answer:
Step-by-step explanation:
They gave you an easy triangle. You can tell by the coordinates that X and Z are horizontally aligned, and Y and Z are vertically aligned, so Z is a right angle.
Area = 0.5(XZ)(YZ) = 0.5(3)(3) = 4.5 square units.
6/14=x/20 cross multiply and get 14x=120 divide and get 8 2/30
