I must assume that you meant "sqrt(191)."
What's the first perfect square greater than 191? Answer: 196 = 14^2
What's the first perfect square smaller than 191? Answer: 169 = 13^2
Note how 169 < 191 < 196. Thus, the square root of 191 lies between 13 and 14.
Let
x--------------> the third stone measure
we know that
the recommended height for the bench is ------> 20 in
20=[4 3/8]+[4 1/2]+[5 1/4]+[x]
4 3/8---------> (4*8+3)/8=35/8
4 1/2---------> (4*2+1)/2=9/2
5 1/4---------> (5*4+1)/4=21/4
20=[35/8]+[9/2]+[21/4]+[x]
<span>x=20-(35/8)-(9/2)-(21/4)</span>
x=20-(35+4*9+2*21)/8----->
20-113/8------- > (8*20-113)/8
x=47/8----------
> 5.875=5 7/8

answer is 5 7/8 in</span></span>
Answer:
26
Step-by-step explanation:
25/750=0.033333
0.033333x780=26
Answer:
Option B. 
Step-by-step explanation:
we know that
The volume of a cone is equal to

Solve for the radius r
That means-----> isolate the variable r
Multiply by 3 both sides

Divide by
both sides

square root both sides

"<span>y/5+8=7, what is the value of y/5-2?" Simplify the first equation:
y/5 = 7 - 8, or -1, so y/5 = -1, or y = -5.
Then y/5 - 2 equals -5/5 - 2, or -3.</span>
