Gym A charges 9 per hr
Gym B charges 0.75 per 5 minutes....0.75/5 = 0.15 per minute...60 minutes in an hr.....60 * 0.15 = 9 per hr
so Gym A and Gym B charge the same hourly rate
Step-by-step explanation:
the side lengths of the base (the ground triangle) are equal. that means every ground side length is 8 in.
and that also makes the 3 triangles of the side areas of the pyramid equal.
so, for the surface area of the pyramid we need to calculate the area of one side area triangle, multiply it by 3 (as we have 3 side areas) and add the area of the ground triangle.
the area of a triangle is
baseline × height / 2
so, for a side area triangle we get
8 × 14 / 2 = 8×7 = 56 in²
all 3 side areas together are then
3×56 = 168 in²
the ground area triangle is then
8 × 6.9 / 2 = 4 × 6.9 = 27.6 in²
so, the total surface area of the pyramid is
168 + 27.6 = 195.6 in²
Answer:
The answer is D.
Step-by-step explanation:
Answer:
on the x axis you find 34 and go to the y axis and find -8 and then draw your finger until they meet. Wherever they meet is your point.
Answer:
y=[x+1]-3 because it's at the end of the line
