Answer:

4^0

Step-by-step explanation:

The rules of exponents are ...

(a^b)(a^c) = a^(b+c)

(a^b)/(a^c) = a^(b-c)

So, your expression simplifies to ...

$4^5\times4^{-7}\div4^{-2}=4^{5-7-(-2)}=\boxed{4^0}$

Use a net to find the surface Area of the square pyramid The height of the pyramid is 9 yes and the base sides are all 2.5 yrds

Cerrena [4.2K]

Answer:

$Area = 51.68yd^2$

Step-by-step explanation:

Given

$h = 9yd$ -- height

$a = 2.5yd$ --- base sides

Required

Determine the surface area

The net is not given. So, I will solve directly.

The surface area is calculated as:

$Area = a^2 + 2a\sqrt{\frac{a^2}{4} + h^2}$

So, we have:

$Area = 2.5^2 + 2*2.5\sqrt{\frac{2.5^2}{4} + 9^2}$

$Area = 6.25 + 5\sqrt{\frac{6.25}{4} + 81}$

$Area = 6.25 + 5\sqrt{1.5625 + 81}$

$Area = 6.25 + 5\sqrt{82.5625}$

$Area = 6.25 + 5* 9.086$

$Area = 51.68yd^2$

Find two numbers whose sum is 20 and difference is 1

MA_775_DIABLO [31]

Divide 20 by 2
20/2 = 10
Add and subtract 0.5* from 10
10 + 0.5 = 10.5
10 - 0.5 = 9.5
Those two numbers are your answer.

*The reason why we used 0.5 because the difference is 1, so divide 1 by 2.

Have an awesome day! :)
