Match the amounts and tip or tax rates in the first column to the total costs in the second column.
gogolik [260]

Answer:

1. $132.24

2. $55.89

3. $1336.66

4. $258.19

5. $57.86

Step-by-step explanation:

Simply use this equation.

\frac{InitialValue}{100} = \frac{x}{TaxPercentage}

Substitute in our values, using No.1 as our example.

\frac{123.01}{100}  = \frac{x}{7.5}

Cross multiply

922.575 = x100

Solve for x by dividing by 100.

x = 9.22575

Now add x to the initial value.

9.22575 + 123.01 = 132.23575

Round to the nearest hundredth for the answer.

$132.24

Give the equation of the circle centered at the origin and passing through the point (0,3)
rusak2 [61]

Answer:

The equation would be x^2 + y^2 = 9

Step-by-step explanation:

In order to find this, start with the base form of the circle.

(x - h)^2 + (y - k)^2 = r^2

Now we input the center as (h, k).

(x - 0)^2 + (y - 0)^2 = r^2

x^2 + y^2 = r^2

Now we can input the radius of 3 in for r

x^2 + y^2 = 3^2

x^2 + y^2 = 9

Explain in words how you would get the answer to this equation 9x-7=-7=0
goblinko [34]

Answer:

See below

Step-by-step explanation:

9x-7=0

We want to isolate the variable, or in other words, get x alone.

The first step is to add 7 to each side to get the constant on one side and the variable on the other

9x-7+7 = 0+7

9x =7

The since we are multiplying x by 9, we need to do the opposite to isolate it.  We will divide by 9.  What we do to one side, we do to the other.  Divide both sides by 9

9x/9 = 7/9

x =9

We have successfully isolated the variable and solved for x.
