Answer:

50 blocks

Step-by-step explanation:

First of all, you need to label you're proportions, which can be mm/blocks.

Then, for 1 block, it is 20 mm because the block is 2 cm, which is equal to 20 mm. So for you're proportion, it is 20 mm/1 block.

Finally, you need to find the total amount of blocks that equals 1000 mm. So you can multiply the 20 mm by 50 to get the 1000 mm. What you do at the top, you do at the bottom, so you also have to do 1 block by 50 to get 50 blocks

So for you're final answer/proportion, it is mm/blocks = 20/1 = 1000/50 and you're final answer is 50 blocks

Hope this helps : )

Answer:

A

Step-by-step explanation:

When solving for x as an exponent, we need to use logarithms in order to undo the operation and rearrange the terms. We use log rules to bring down the exponent and solve. Logarithms are the inverse operations to exponents and vice versa. We have one special kind of logarithm called the natural logarithm whose base is e. We write it as ln. Since our base is e here, we will use the natural logarithm to rearrange and isolate x.

e^{4x-1} =3

We begin by applying the natural logarithm to each side.

ln(e^{4x-1}) =ln(3)

Log rules allow use to rearrange the exponent as multiplication in front of the log.

(4x-1)ln(e) =ln(3)

ln e as an inverse simplifies to 1.

(4x-1)(1)=ln(3)

We now apply the inverse operations for subtraction and multiplication.

4x-1+1=1+ln(3)\\4x=1+ln(3)\\\frac{4x}{4} =\frac{1+ln3}{4} \\x =\frac{1+ln3}{4}

Option A is correct.

Answer:

  $222,822.57

Step-by-step explanation:

The account balance is given by ...

  A = P·e^(rt)

where P is the principal invested at interest rate r for t years.

  A = $25,000×e^(0.0875·25) ≈ $222,822.57

Which values are solutions to the inequality below? <br><br>Check all that apply.
matrenka [14]
You have this....

√x > 8

This means that the square root of something is greater than 8.

So plug in everything for x and find the answer.

Anything 64 and below is NOT THE ANSWER.

√64 = 8, and 8 is not greater than 8, so anything 64 and below is wrong.

So the answer is...

D and F.
