Answer:

45 inches

Step-by-step explanation:

85-40=45

b=45

how I know?

use the formula c^2-a^2=b^2

85 being c, a being 40 and b being 45

Answer:

Hello! answer: b = 75

Step-by-step explanation:

We have to find b so we have to work backwards to find the answer the steps would be to find c^2 subtract that by a^2 and then you get b^2 and have to find out what multiplied by itself equals b^2 so... 85 × 85 = 7225 40 × 40 = 1600 7225 - 1600 = 5625 75 × 75 = 5625 therefore b = 75 hope that helps!

A community park is shaped like a trapezoid with a height of 30 yd, a top base of 25yd,and a bottom base of 33yd. The park has a

Likurg_2 [28]

Answer: 819.73 yd²

<u>Step-by-step explanation:</u>

$A_{trapezoid} = \frac{b_{1}+b_{2}}{2}*h$

= $\frac{25+33}{2}*30$

= $\frac{58}{2}*30$

= 29 * 30

= 870

$A_{circle} = \pi r^{2}$

= π(4)²

= 16π

≈ 50.27

Area of the park = $A_{trapezoid} - A_{circle}$

= 870 - 50.27

= 819.73

Worth 12 Points, i spent 24

rewona [7]

Answer:

$\displaystyle m^{\frac{35}{12}}n^{-\frac{28}{15}}=\frac{m^{\frac{35}{12}}}{n^{\frac{28}{15}}}$

Step-by-step explanation:

The relevant rule of exponents is ...

(a^b·c^d)^e = a^(be)·c^(de)

Then ...

(m^(5/4)·n^(-4/5))^(7/3) = m^(5/4·7/3)·n^(-4/5·7/3)

= m^(35/12)·n^(-28/15)

Since you want positive rational exponents, you can write this as ...

= m^(35/12)/n^(28/15)
