Answer:

Addition property of equality formula

Lesson Summary

We learned that the addition property of equality tells us that if we add the same quantity to both sides of an equation, then our equation remains the same. The formula is if a = b, then a + c = b + c.

If you earn $48,000 per year, how much will you receive on a biweekly basis?

Harrizon [31]

$48,000 a year is $1,846.15 biweekly before taxes and approximately $1,384.62 after taxes. Paying a tax rate of around 25% and working full-time at 40 hours a week, you would earn $1,384.62 after taxes. To calculate how much you make biweekly before taxes, you would multiply $23.08 by 40 hours and 2 weeks

Answer:

Step-by-step explanation:

x^0=1 so you can cancel it out. when a number has a negavite exponent, you have to invert it. That means y^-6 goes at the denominator and becomes y^6 and z^-6 goes up to the numerator and becomes z^6.

$1500 is invested at a rate of 3% compounded monthly. Write a compound interest function to model this situation. Then find the

Marianna [84]

Answer:

Equation: $F=1500(1.0025)^{12t}$

The balance after 5 years is: $1742.43

Step-by-step explanation:

This is a compound growth problem . THe formula is:

$F=P(1+\frac{r}{n})^{nt}$

Where

F is future amount

P is present amount

r is rate of interest, annually

n is the number of compounding per year

t is the time in years

Given:

P = 1500

r = 0.03

n = 12 (compounded monthly means 12 times a year)

The compound interest formula modelled by the variables is:

$F=1500(1+\frac{0.03}{12})^{12t}\\F=1500(1.0025)^{12t}$

Now, we want balance after 5 years, so t = 5, substituting, we get:

$F=1500(1.0025)^{12t}\\F=1500(1.0025)^{12*5}\\F=1500(1.0025)^{60}\\F=1742.43$

The balance after 5 years is: $1742.43

Answer:

a) The Total fee, that Mike charges for 4 hours of instruction is $152

b) The total fee, that Tony charges for 4 hours of instruction is $148

c) The difference between total fee Mike and Tony charge for 4 hours of instructions is $4

Step-by-step explanation:

a) What is the total fee, that mike charges for 4 hours of instruction.

Mike charges $12 for travel expenses and $35 per hour for instruction.

So, the equation will be: $y=35h+12$ where h is number of hours and y is cost

Put h=4 and find cost

$y=35h+12\\y=35(4)+12\\y=140+12\\y=152\\$

So, the Total fee, that Mike charges for 4 hours of instruction is $152

b) What is the total fee, that Tony charges for 4 hours of instruction

Tony's fee can be modelled by C=32h+20 where h is number of hours and C is cost

Put h=4

$C=32h+20\\C=32(4)+20\\C=128+20\\C=148$

So, the total fee, that Tony charges for 4 hours of instruction is $148

c) What is the difference between total fee Mike and Tony charge for 4 hours of instructions.

Cost for Mike = $152

Cost for Tony = $148

Difference = 152 - 148 = 4

So, the difference between total fee Mike and Tony charge for 4 hours of instructions is $4
