Answer:
Step-by-step explanation:
we know that
1 mile=63,360 inches
step 1
Find the circumference of the wheels
we have
-----> the radius is half the diameter
substitute
assume
Remember that
The circumference of the wheels represent one revolution
Convert 59 miles per hour to inches per minute
using proportion find the number of revolutions
therefore
substitute
Answer:
you will add the numerator and the denominator and or you look for lowest common factor
Answer:
C. 10
Step-by-step explanation:
Slope / Gradient: (y - y¹) / (x - x¹)
Using points (-20, 0) and (-10, 1)
= [-20 - (-10)] / [0 - 1]
= -10 / -1
= 10
Area of a trapezoid: 1/2(a + b)*h, where a and b are the lengths of the two bases of a trapezoid and h is the height.
Plug 22 and 44 for a and b, respectively. Plug 15 for h.
1/2(22 + 44)*15
1/2(66)*15
1/2(990) = 495
b) 495 in²
