A = (b1 + b2) h / 2
I'm so confused, and i need to solve for h.

Answers

Answer:

Step-by-step explanation:

Begin by multiplying both sides by 2

2*A  =  2*(b1 + b2) * h/2                        Cancel the 2s

2A = (b1 + b2 ) * h                                 Divide both sides by (b1 + b2)

2A/(b1 + b2) = (b1 + b2)*h / (b1+b2)     Cancel B1 + b2

2A/(b1 + b2) = h

b. Does a12 x a4 = a8 x a8 for all values of a? Explain.

Answers

Answer:

We can use the Laws of Exponent to rewrite both sides of the equation:

Let a¹² x a⁴ = a⁸ x a⁸

⇒        a¹²⁺⁴ = a⁸⁺⁸

             a¹⁶ = a¹⁶  ✅

⇒  a¹² x a⁴ = a⁸ x a⁸ is true for all values of a.

Explanation:

The equation a¹² x a⁴ = a⁸ x a⁸ is true because, on both the RHS and LHS of the equation, both terms in 'a' have exponents that when added (Law of Multiplication of Exponents) are equal to each other, i.e. 12+4 = 8 + 8.

Rectangle PROM has a perimeter of 42 inches, and OR = 8 inches. What is the area of the rectangle PROM?

Answers

Answer:

104 in²

Step-by-step explanation:

If OR = 8 then 8 x 2 = 16

PM= (42-16)/2=13

Therefore area = 8 x 13 = 104 in²

To check the perimeter is right:

2(8+13) = 42

Answers

Answer:

If you've written it correctly, the answer is 2.25.

Step-by-step explanation:

Can be written as:

0.5 * (2.5 * 4.8 - 7.5).

Perform the multiplications inside the brackets, first:

0.5 * ( 12 - 7.5)

Then perform the remaining arithmetic inside the brackets:

0.5 * ( 4.5)

Perform the last arithmetic:

2.25.

Again, that's if you've written it correctly, and when you say 4 4/5-7 1/2 this actually means four and four fifths (4.8) minus seven and a half (7.5).

A skyscraper is a rectangular prism with a height of 398 meters. The bases are squares with sides that are 62 meters. What is the surface area of the skyscraper?

Answers

Answer:

106,392 meters squared.

Step-by-step explanation:

Surface area of a rectangular prism or cuboid is given by:

SA = 2 (lw + wh + lh)

where:

· l is the length of the cuboid.

· w is the width of the cuboid.

· h is the length of the cuboid.

Here we have h = 398 m, l = w = 62 m because this is a square base.

So we get:

SA = 2 ( 398 · 62 + 62² + 398 · 62)

= 2 (24676 + 3844 + 24676)

= 2 · 53196

= 106392 m²
