Answer:
Step-by-step explanation:
4/30 ÷ 7/48
=4/30 * 48/7
=4/15*24/7
=96/105
So its this answer because the y is equal to the x plus the y-intercept but the y is 0 so; y=5/2x
The bottom trapezoid is
(1/2) * h * (b2 + b1) =
(1/2)*11 * (31+25)
(1/2) * 11 * 56
308
The top parallelogram is
b * h = 12 * 14 = 168
308 +168 = 476 ft^2
Letter B
By definition the rate of change of a function is given by:

Or equivalently:

Substituting the values given in the problem we have:

Rewriting we have:
Answer:
the rate of change of the ramp is:
10) The GCF of a set of numbers is the largest number that divides into both numbers.
The GCF of 24 and 36 is 12.
15)
can be simplified by dividing the top (numerator) and the bottom (denominator) by the GCF. The GCF of 30 and 54 is 6. The new fraction is
. 6/9
20) The GCF of
is 11. The new fraction is
. 5/8
