Answer: Her net income is less than $120.

Step-by-step explanation:

Based on the information given, the gross income for Amy will be:

= $120

Net income is the income that an individual has left after tax and every other necessary deductions have been removed. Therefore when this is done, the net income for Amy will be less than $120

Which expression is equivalent to 144^3/2
Tju [1.3M]

Answer:

\large\boxed{144^\frac{3}{2}=1728}

Step-by-step explanation:

\sqrt[n]{a^m}=a^\frac{m}{n}\\\\144^\frac{3}{2}=144^{1\frac{1}{2}}=144^{1+\frac{1}{2}}\qquad\text{use}\ a^na^m=a^{n+m}\\\\=144^1\cdot144^{\frac{1}{2}}=144\sqrt{144}=144\cdot12=1728

The problem below has been solved incorrectly. Identify and explain the error.
mylen [45]

Answer:

If you look over the steps you can see that until 4x + x + 3 = 18, evertything is dandy. But the step after that 4x + x =21 seems a bit fishy.

Think about it they subtract 3 from both sides so the first side is correct

4x + x, but they added 3 to the other side:

(4x+x+3) - 3 = 18 - 3\\4x+x = 15

not

4x+x = 21

Then we solve for 4x + x = 15

5x = 15\\x = \frac{15}{5} \\x = 3

To solve for y we use :

y = x+3

y = 3+3 = 6

so (3,6) is the right answer

The fourth graders are helping raise money for the local animal shelter they hoped to raise 1,000. so far they have made 465 in
vredina [299]

The fourth graders raised 175 more than 1,000 for the local animal shelter.

First, let us identify the given.

  • Target value to raise= 1,000
  • Profit from bake sale= 465
  • Profit from t-shirt sales= 710

How much money did the fourth graders raise? The sum of the profit from the bake sale and t-shirt sales determines the total money raised.  

Total money= Profit from bake sale + Profit from t-shirt sales

Total money= 465 + 710

Total money= 1175

How much more than 1,000 have the fourth graders raised? This amount is equivalent to the difference between the total money raised and the target amount, 1,000.

Total money-target amount

1175-1000= 175

Use completing the aquare to solve for x in the equation (x+7)(x-9)=25​
Tema [17]

Answer:

x = 1 + sqrt(89) or x = 1 - sqrt(89)

Step-by-step explanation:

Solve for x:

(x - 9) (x + 7) = 25

Expand out terms of the left hand side:

x^2 - 2 x - 63 = 25

Add 63 to both sides:

x^2 - 2 x = 88

Add 1 to both sides:

x^2 - 2 x + 1 = 89

Write the left hand side as a square:

(x - 1)^2 = 89

Take the square root of both sides:

x - 1 = sqrt(89) or x - 1 = -sqrt(89)

Add 1 to both sides:

x = 1 + sqrt(89) or x - 1 = -sqrt(89)

Add 1 to both sides:

Answer: x = 1 + sqrt(89) or x = 1 - sqrt(89)
