Can someone help me with this
Oksanka [162]

Answer:

20

Step-by-step explanation:

We know that the formula for the area of something is 1/2 * base * height

So we multiply 1/2 * 8 * 2 for The first triangle and get 8

Repeat for the other 3:

1/2* 2*2 = 2

8+8+2+2 = 20

* there are 4 triangles but I only needed to do the formula for two of them because they have identical triangles.

I hope this helps :)

An amount of $15,000 is invested in a fund that has a return of
IrinaVladis [17]

Answer:

$12000 should be invested in a fund with a 4% return.

Step-by-step explanation:

Consider the provided information.

An amount of $15,000 is invested in a fund that has a return of  6%.

We need to calculate how much money is invested in a fund with a 4% return if the  total return on both investments is $1380.

Let $x should be invested in a fund with a 4% return.

The above information can be written as:

1380=15000\times 6\%+x\times 4\%

1380=15000\times \frac{6}{100}+x\times \frac{4}{100}

1380=150\times6+x\times 0.04

1380-900=0.04x\\480=0.04x\\x=12000

Hence, $12000 should be invested in a fund with a 4% return.
