V = Bh for h. A. h = BV B. h=B/V C. h=V/B D. h = V – B

1 answer:

5 0

C. h=V/B to solve for this you need to get the variable h by itself and since h is being multiplied to B you use the opposite operation of division by divide both sides by B. Then you have h solved for h=V/B

For every x value, there should be only one y value. Or, for every input there is only one output.

A - Incorrect - there are two 2's for the x values and each of them has a different y value

B - Correct - all of the x values are different and all of the y values are different

C - Incorrect - there are two 11's for the x values and each of them has a different y value

D - Incorrect - there are two 3's for the x values and each of them has a different y value

Hope this helps! :)

Solve equation: <br> 8n-7=-12+3n

lutik1710 [3]

To solve this problem, the first thing we have to do is regroup the terms so that we can then subtract, simplify, subtract, and finally simplify again.

But first we must know.

<h3>¿What are the equations?</h3>

Equations are those mathematical equalities divided between two expressions which are called members and separated by their equal sign, in which known elements and unknown or unknown data appear, related by mathematical operations.

<h3>We solve the problem:</h3>

8n - 7 = -12 + 3n
8n - 7 = 3n - 12
8n - 7 - 3n = -12
5n - 7 = -12
5n = -12 + 7
5n = -5
N = -1

Now we must check our results.

8n -7 = -12 + 3n

8 × - 1 - 7 = -12 + 3 × - 1

- 8 - 7 = - 12 - 3

- 15 = - 12 - 3

- 15 = - 15

So, our results are correct, the answer is n = - 1

¡Hope this helped!

Michael paints a circular

BigorU [14]

Answer:

90.25π

Step-by-step explanation:

The formula for solving the area of a circle is πr².

r is the radius. We can find the radius by splitting the diameter in half: 19/2 = 9.5.

We can apply the area formula and we get π9.5² and the answer is 90.25π.

Hiro rolls a fair pair of six-sided dice. The sample space of all possible outcomes is shown below. Let AAA be the event that th

Eva8 [605]

Step-by-step explanation:

P(A or B) = P(A) + P(B) − P(A and B)

P(A or B) = 6/36 + 5/36 − 0/36

P(A or B) = 11/36

Jacob is unsure how long it will take to save $50,000. He knows that he'll make an initial investment of $5,000, and he can earn

maksim [4K]

Answer:

It will take Jacob 36 years to reach his goal

Step-by-step explanation:

In this question, Jacob is intending to save $50,000 but he is doing this by saving $5,000 at an interest which is compounded two times a year (semi-annually). We are tasked with calculating the number of years it will take him.

Mathematically, to solve this, what we use is the compound interest formula.

This is;

A = P(1 + r/n)^nt

Where in the question A is our savings target of $50,000

P is our initial amount saved of $5,000

r is the rate at 6.5%

n is the number of times interest will be compounded per year= 2

and t is the number of years it will take.

We plug all these values respectively to yield;

50,000 = 5,000(1 + 0.065/2)^(2t)

Divide through by 5,000

we have;

10 = (1.0325)^2t

Take the logarithm of both sides

Log 10 = Log (1.0325)^2t

Log 10 = 2tLog (1.0325)

2t = Log10/Log1.0325

2t = 72

t = 72/2

t = 36 years
