Answer:
C.-19
Step-by-step explanation:
add -2 to each interval
6 to 7 =-11-2=-13
7 to 8 =-13-2=-15
8 to 9=-15-2=-17
9 to 10=-17-2=-19
Well it depends on where the number is at. So you have to estimate to the closest number on the answers.
Ok?
A street light is mounted at the top of a 15-ft-tall pole. A man 6 ft tall walks away from
<span>the pole with a speed of 5 ft/s along a straight path. How fast is the tip of his shadow moving when </span>
<span>he is 40 ft from the pole? </span>
<span>Solution: USE SIMILAR TRIANGLES. Let d be the distance between the man and the pole and let x be the length of the man's shadow. Then x=(d + x) = 6=15, so 15x = 6x + 6d and 9x = 6d. Then </span>
<span>x = (2=3)d. The problem wants us to find d(d + x)=dt = d(d)=dx + dx=dt, since this is the speed </span>
<span>of the tip of his shadow. We know dx=dt = (2=3)d(d)=dt and we know d(d)=dt = 5 ft/s, from the </span>
<span>problem. Then d(d + x)=dt = (5=3)d(d)=dt = 25=3 ft/s.</span>
Finding the area of a square is easy as long as we know one side length. Since all of the sides are the same, we can do s^2 to get our answer. This shows that the area of the square is approximately 75.111 inches squared.
Answer:
I'm pretty sure 10% of 82 is 8.2 and 60% of 82 is 49.2
If I'm wrong I'm sorry.......
