Kay [80]3 years ago

Answer:

Value of [(\frac{2}{3}) ^0]^{-3} is, 1

Step-by-step explanation:

To find the value of [(\frac{2}{3})^0]^{-3}

Using exponents power rule:

(a^m)^n = a^{mn}

then;

(\frac{2}{3})^{0 \cdot (-3)}

Simplify:

(\frac{2}{3})^{0}

By Zero exponent rule: Anything raised to the power 0 is 1. i.e,

a^0 = 1

then;

(\frac{2}{3})^{0} = 1

Therefore, the value of [(\frac{2}{3}) ^0]^{-3} is, 1

How do you solve this? r^2+32=12r
Andre45 [30]

Answer:

r = {-8, -4}

Step-by-step explanation:

Simplifying

r2 = -32 + -12r

Solving

r2 = -32 + -12r

Solving for variable 'r'.

Reorder the terms:

32 + 12r + r2 = -32 + -12r + 32 + 12r

Reorder the terms:

32 + 12r + r2 = -32 + 32 + -12r + 12r

Combine like terms: -32 + 32 = 0

32 + 12r + r2 = 0 + -12r + 12r

32 + 12r + r2 = -12r + 12r

Combine like terms: -12r + 12r = 0

32 + 12r + r2 = 0

Factor a trinomial.

(8 + r)(4 + r) = 0

Subproblem 1

Set the factor '(8 + r)' equal to zero and attempt to solve:

Simplifying

8 + r = 0

Solving

8 + r = 0

Move all terms containing r to the left, all other terms to the right.

Add '-8' to each side of the equation.

8 + -8 + r = 0 + -8

Combine like terms: 8 + -8 = 0

0 + r = 0 + -8

r = 0 + -8

Combine like terms: 0 + -8 = -8

r = -8

Simplifying

r = -8

Subproblem 2

Set the factor '(4 + r)' equal to zero and attempt to solve:

Simplifying

4 + r = 0

Solving

4 + r = 0

Move all terms containing r to the left, all other terms to the right.

Add '-4' to each side of the equation.

4 + -4 + r = 0 + -4

Combine like terms: 4 + -4 = 0

0 + r = 0 + -4

r = 0 + -4

Combine like terms: 0 + -4 = -4

r = -4

Simplifying

r = -4

Solution

r = {-8, -4}

Ethan works in a department store selling clothing. He makes a guaranteed salary of $500 per week, but is paid a commision on to
ElenaW [278]

The total amount of money Ethan made in a week including commission is $812.5

<h3>Total income</h3>

  • Total sales for the week = $1250
  • Base salary = $500
  • Percentage commission = 25%

Amount of commission earned = 25% of $1250

= 25/100 × $1,250

= 0.25 × 1250

= $312.5

Total earnings = Base salary + Amount of commission earned

= $500 + $312.5

= $812.5
