2. In the ratio of 3:2:2, three brothers invested a total of 249,000 to open a store. Find each

GaryK [48]

Answer:

$106,714.29

$71,142.86

Step-by-step explanation:

There's a total of 7 pieces that they invested (3 + 2 + 2 = 7) so you can do 249,000 / 7 to find what each piece was worth.

249000/7 = about 35571.43

(you always have to round money to 2 decimal places)

Then the amount each brother spent would be:

3 * 35571.43 = 106714.29

2 * 35571.43 = 71142.86

Which one doesn’t belong with the other three? Explain your reasoning plz plz answer #3

The box provides some examples of how exponents can be used to shorten repeated multiplication. The first, third, and fourth boxes all show how the repeated multiplication of 2, 3, and 5 can all be abbreviated as $2^4, 3^2$ and $5^3$ . The only expression which doesn't belong is $3+3+3+3=3(4)$ , because it's showing how repeated addition can be shortened to multiplication.
