Answer:

H = 2        S = 50    A = 50.2

Step-by-step explanation:

A=2πrh+2πr2

S = 2tr2 + 2trh

S = 2 (t x r) + (h x 2t) x r   Try out ^2 for Radius

S = 2t x r^2 + r x h x 2t  Rearrange back and cross out for square^2

S = 6t x 4 + 6t x r x h Cross out for t

S = 6 x 4 + 6 x 2 x h  Balance out...

S= 24 + 12 x 2    Find h = 2

S = 36 + 24

S=  50 sq2

A = 50. 2

R = 2

H = 2  

Checker

Area = 6.28318530718 x 4 + 6.28318530718  x 2 x 2 = 50.27sq2

To determine the number of deer in a game​ preserve, a conservationist catches 594 ​deer, tags them and lets them loose.​ Later,
Alex73 [517]

We have been given that to determine the number of deer in a game​ preserve, a conservationist catches 594 ​deer, tags them and lets them loose.​ Later, 748 deer are ​caught; 187 of them are tagged. We are asked to find the number of deer in the preserve.

We will use proportions to solve our given problem.

\frac{\text{Total deer population}}{\text{Caught deer population}}=\frac{\text{Caught deer}}{\text{Tagged deer}}

\frac{\text{Total deer population}}{594}=\frac{748}{187}

\frac{\text{Total deer population}}{594}\times 594=\frac{748}{187}\times 594

\text{Total deer population}=4\times 594

\text{Total deer population}=2376

Therefore, there are 2376 deer in the preserve.

I DON'T UNDERSTAND HOW THE ANSWER IS 15% PLEASE EXPLAIN
sweet [91]

Answer:

15%

Step-by-step explanation:

17/20 the 17 is the part, and the 20 is the whole

17/20 = x/100

cross multiply

17*100= 1,700 divide by 20

=85

The price reduced to 85% the original price, but to find out how much it changed, you have to subtract the part from the whole meaning

100% - 85% = 15%
