A right triangle has legs of lengths 14 and 16 inches. Find the length of
Mice21 [21]

Answer:

about 21.3

Step-by-step explanation:

I found the hypotenuse value by doing the Pythagorean theorem.

a^2+b^2=c^2.

"a" and "b" are the values of the legs, and "c" is the value of the hypotenuse. So, "a" is 14 and "b" is 16.

14^2+16^2=c^2

196+256=452.

Now, I found the square root of 452. The square root of 452 is 21.26029163. This value rounded to the nearest tenth is 21.3.

In conclusion, the length of the hypotenuse rounded to the nearest tenth is 21.3 inches.

inysia [295]

Answer:

Yes ,is a reasonable amount. If she has $20 she will have enough to buy the shirt

Step-by-step explanation:

we know that

The total amount is equal to the price of the shirt plus the sales tax

we have that

100\%+4.8\%=104.8\%=104.8/100=1.048

Multiply 1.048 by the cost of the shirt

\$18.95(1.048)=\$19.86

Compare

\$19.86 < \$20

therefore

Yes ,is a reasonable amount. If she has $20 she will have enough to buy the shirt
