A scuba diver was 53 below the oceans surface. If he rises 25 feet, what is the new depth?
You subtract 25 ft from 53 ft leaving you with 28 ft.
53 ft
- <u>25 ft</u>
28 ft below the surface

Answer:
78
Step-by-step explanation:
7+8/2 multiply by 6
Answer:
D, E &F
Step-by-step explanation:
Lets's go down the list and evaluate each choice
A. (3^8) / (3^4) = 3^ (8-4) = 3^4 (≠ 3^2)
B. 6²/2 = (2 x 3)²/2 = (2²·3²)/2 = 4·3²/2 = 2.3² (≠ 3^2)
C. (3^5) ·(3^3) = 3^ (5+3) = 3^8 (≠ 3^2)
D 3·3 = 3^2 (Answer)
E. (3^12) / (3^10) = 3^ (12 -10) = 3^2 (Answer)
F. (3^-3) / (3^-5) = 3^ [ -3 -(-5) ] = 3^ (-3 + 5) = 3^2 (Answer)
<span>Total sample space = 20C2 = 190
The number of ways of selecting 2 balls of same color from a suit of 15 red balls
15C2 = 105
The number of ways of selecting 2 balls of same color from a suit of 5 blue balls
5C2 = 10
Thus the probability that the person picks 2 balls of same color = [105/190 + 10/190]
= 115/190 = 23/38</span>
Let x be the original radius. Given that a semicircle will have an arc length of half of a circumference and C=2pr, the arc length will be just pr.
Now the difference of arc is then going to be:
p(6+x)-px
p(6+x-x)
6p inches
So the arc will be 6p inches longer. Or if you wish to approximate...
≈18.85 inches
