Well so far, Kate has saw 65% of her workout
65% of total = 26
0.65 * t = 26
t = 26/0.65
t = 40 laps
1 revolution of a circle = circumference of that circle.
<span>1 revolution of a circle with the diameter of 28 inches = </span><span><span>πd=28π</span><span>πd=28π</span></span><span> inches. Hence, x revolutions per second = </span><span><span>28πx</span><span>28πx</span></span><span> inches per second = </span><span><span>60∗28πx</span><span>60∗28πx</span></span><span> inches </span>per minute.

Answer:
Step-by-step explanation:
hello :
f(x)=4^x so : f(-2)=4^(-2) = 1/4^2 = 1/16
125+85+22.5+22.5+65=320
320x0.06=9.2
12x10=120
320+19.2+120=459.2
