7/4(53) + 6
92.75 + 6
98.75
Answer:
well for me I think
Step-by-step explanation:
2/3×2/3
4/9
since they are replacing the black marbles back
The answers are f = 2 and p = -2
Let the length of the diameter be d and radius be r, thus to solve for d we proceed as follows:
r²+31²=(r+15)²
solving for d we solve for r
r²+961=r²+30r+225
putting like terms together we obtain:
r²-r²+961-225=30r
736=30r
solving for r
r=24.53
thus
d=24.5333×2
d=49.067~49.1
Answer is D. 49.1
