Answer:

40 years old

Step-by-step explanation:

Let's imagine a+b=63

63-12=51 (since they were both 6 years younger)

A is double B

34+17=51

34/2=17

You need to add the 6 years back onto the mothers age - 34+6=40

Answer:

You should receive 286.0821056 US dollars

Step-by-step explanation:

* Lets explain how to solve the problem

- The exchange rate is USD/EURO 0.6991

- That means 1 USD = 0.6991 EURO

- You have 200 EURO

- You want to convert them to US dollars

∵ 1 dollars = 0.6991 euro

USD : EURO

1 : 0.6991

x : 200

∴ $\frac{1}{0.6991}=\frac{x}{200}$

- By using cross multiplication

∴ 0.6991 x = 200

- Divide both sides by 0.6991

∴ x = 286.0821056

∵ x represents the amount of US dollars

∴ <em>You should receive 286.0821056 US dollars</em>

The two right triangular prisms are similar solids.

Zanzabum

Answer:

<h2>The volume of the larger prims is eight times greater than the smaller prism.</h2>

Step-by-step explanation:

If the scale factor of the larger prims to the smaller prism is 3, that means each side is triple.

We know the a triangular prims has a volume defined by

$V_{small} =\frac{b \times h_{1} }{2} \times h_{2}$

If we take that formula as the smaller prism, then the larer prism has a volum of

$V_{large} =\frac{2b \times 2h_{1} }{2} \times 2h_{2}=8(\frac{b \times h_{1} \times h_{2} }{2} )$

If we compare, we can deduct that

$V_{large}=8V_{small}$

In words, the volume of the larger prims is eight times greater than the smaller prism.
