Answer:

9 hours

Step-by-step explanation:

He earns 11 for every hour,

11/1

And he earned 99, but we don't know how many hours

99/x

Set the expressions equal to each other

11/1=99/x

Cross multiply

11x=99

Divide by 11 on both sides

x=9

So he worked 9 hours

Hope this helps! :)

Answer:

$3942.72

Step-by-step explanation:

The compound interest formula is ...

A = P(1 +r)^t . . . . P invested at rate r for t years

You have P = 3500, r = 0.015, t = 8. Put these values into the formula and do the arithmetic.

A = $3500(1.015^8) ≈ $3942.72

Carl will have $3942.72 in the account after 8 years.

Write the expression in repeated multiplication form. Then write the expression as a power. (-8)^3*(-8)^4 The expression in repe

Makovka662 [10]

Given:

The expression is

$(-8)^3\cdot (-8)^4$

To find:

The expression in repeated multiplication form and then write the expression as a power.

Solution:

We have,

$(-8)^3\cdot (-8)^4$

The repeated multiplication form of this expression is

$=[(-8)\cdot (-8)\cdot (-8)]\cdot [(-8)\cdot (-8)\cdot (-8)\cdot (-8)]$

$=(-8)\cdot (-8)\cdot (-8)\cdot (-8)\cdot (-8)\cdot (-8)\cdot (-8)$

Clearly, (-8) is multiplied seven times by itself. So,

$=(-8)^7$

Therefore, the repeated multiplication form of the given expression is $(-8)\cdot (-8)\cdot (-8)\cdot (-8)\cdot (-8)\cdot (-8)\cdot (-8)$ and the expression as single power is $(-8)^7$ .
