Solve for h in the mathematical formula A=1/2(a+b)h

Mathematics
1 answer:
AnnZ [28]2 years ago
8 0

Step-by-step explanation:

Since we arent given enough information to SOLVE for h, I will get as close as I can by rearranging the equation for h

Convert the fraction to a decimal for simplicity

A = 0.5(a + b)h

Divide both sides of the equals by 0.5

A/0.5 = (a + b)h

We can convert A/0.5 into its reciprocal

2 A = (a + b)h

Divide both sides of the equation by the bracketed (a + b)

(2 A)  /  (a + b) = h

Rewritten

<h2>h =  \frac{2A}{(a + b)}</h2>

r-ruslan [8.4K]

Answer:

The answer to your question is The point (-3, 2) is not a solution

Step-by-step explanation:

Inequality

                                   - 4x - 10y < - 9

-point (-3, 2)

Process

1.- To solve this problem, just substitute the point in the inequality and simplify

a) Substitution

                                    -4(-3) - 10(2) < - 9

b) Simplification

                                    12 - 20 < - 9

c) Result

                                        - 8 < - 9

This is false, -8 > -9

To find a slope we have to use this equation:
(y2 - y1 )/(x2 - x1)
and we have two x's and y's
so we will put them in their places....so (1-(-5))/(4-2)
and we will get 6/2 which is 3

Likurg_2 [28]

I believe it is 40. I'm not 100% sure though

Step-by-step explanation:

If 20% of the candy is reese's and there are 8 reese's in the basket, to find the answer you must multiply 8 by 5. You multiply 8 by 5 because to get 100% you have to multiply 20% by 5 to get 100%.
