Crazy boy [7]

Answer:

1. 2^9 = 512

2. 2^3 = 8

3. 7^3 = 343

4. 6^3 = 216

5. 3^6 = 729

Step-by-step explanation:

To start we have to express the number as a multiplication of prime numbers, from there we can take the expression as a power

1.

2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 = 512

2^9 = 512

2.

2 x 2 x 2 = 8

2^3 = 8

3.

7 x 7 x 7 = 343

7^3 = 343

4.

6 x 6 x 6 = 216

6^3 = 216

5.

3 x 3 x 3 x 3 x 3 x 3 = 729

Sal was tired of waiting for Amir to show up at their meeting place, so he started running at an average speed of 4.5 mph withou
sergiy2304 [10]
A=-.25+6.7t, s=.75+4.5t  when Amir catches up a=s so:

-.25+6.7t=.75+4.5t  add .25 to both sides

6.7t=1+4.5t subtract 4.5t from both sides

2.2t=1  divide both sides by 2.2

t=10/22 hr

t≈0.45 hr (to nearest hundredth)
