4 0

Answer:

0.02 (the first option)

Step-by-step explanation:

This is because a proportion means there is division going on. If 5 out of the 250 students have red hair, this creates a fraction of $\frac{5}{250}$ and when you divide this out: 5 ÷ 250, you get 0.02

solmaris [256]

Answer:

Dan will have $1,531.53 after 5 years.

Step-by-step explanation:

To find the answer, you can use the following formula to calculate the future value:

F= P(1 + r)^t

F= Future value

P= Present value= 1200

r= rate of interest= 5%

t= time= 5

F=1200(1+0.05)^5

A=1200(1.05)^5

A=1531.53

According to this, the answer is that Dan will have $1,531.53 after 5 years.

Mathematical word describes both 27x and 6x in the expression 27x+6x?

Maslowich

The mathematical word describing both $27x$ and $6x$ in the expression $27x+6x$ is "<u><em>addition</em></u>"

<h3>How to form mathematical expression from the given description?</h3>

You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.

For the given case, the terms were $27x$ and $6x$ and the expression formed from them is $27x+6x$

This means both the terms were added together, as denoted by '+' (called 'plus') sign.

When two terms are written with 'plus' sign in between, then that means they're added to each other and the result will be addition of both of their's values.

Thus, the mathematical word describing both $27x$ and $6x$ in the expression $27x+6x$ is <u><em>addition</em></u>"
