Food bill before tax $45 sales tax 6.8% tip 24%

Answers

Answer 1

Answer:

The total bill is $58.86

Step-by-step explanation:

Percentages

Before tax, the food bill is $45. Sales tax is 6.8% and the tip is 24%.

Tax is 6.8*$45/100 = $3.06

Tip is 24*$45/100 = $10.80

Total additional charges are:

$3.06+ $10.80= $13.86

Thus, the total bill for the food is:

$45 + $13.86 = $58.86

The total bill is $58.86

If $7,500 investment earns $450 over 3 years what's the interest rate

Answers

Answer:

Rate is 2%

Step-by-step explanation:

Step one:

given data

Principal= $7500

Simple interest= $450

time=3 years.

Applying the simple interest formula which is

SI=PRT/100

Step two:

substitute we have

450=7500*R*3/100

cross multiply we have

45000=22500R

divide both sides by 22500

R=45000/22500

R=2%

Since starting a new recycling plan, Hannah's office recycles 2 kilograms of paper each
week. How many weeks will it take Hannah's office to recycle a total of 8 kilograms of
paper?

Answers

Answer:

Step-by-step explanation:

Known:

Every week Hannah's office recyles 2 kilograms of paper

1 week = 2 kg of paper

To find a rate at which the office recyles paper divide the unit of measurement (kg) by a unit of time (weeks)

So:

2 kg/ 1 week = 2 kg of paper recycled per week

We want to know how many weeks it will take to recycle 8 kg.

Think of it this way.

if you divide kg by kg/week the kg cancel out and you get the unit week.

So divided 8 kg by the rate we discovered (2 kg/week) and you shall get the answer 4 weeks.

Jeff mowed a lawn for $20.00 and received a $5,25 tip. He then washed a car for $12.50. How much money
did Jeff make for completing these two jobs?

Answers

Answer:

See below.

Step-by-step explanation:

Mowing the lawn: $20

Tip: $5.25

Add them together.

[tex]20+5.25=25.25[/tex]

Washing the car: $12.50

Add that to the amount.

[tex]25.25+12.50=37.75[/tex]

Answer: [tex]37.75[/tex]

Answer "and" Explanation:

Depends on whether this is a simple math problem or a riddle. I’m assuming the latter so…

Jeff received $20.00 for providing a lawn mowing service. Jeff received an additional $5.25 tip. Ignoring costs and taxes, Jeff’s gross receipts were $25.25.

Jeff then decided to wash a car. The ways it’s worded leads me to believe he spent $12.50 on the car wash.

So, $25.25 - $12.50 = $12.75

Alternatively, if Jeff was paid to wash the car then:

$20.00 + $5.25 + 12.50 = $37.75

So the Answer will be: $37.75

Which equation represents the relationship between the
number of pets Scott watches and his fees?

Answers

The slope is the change in y over change in x

Given the points (1,8), (2,11), (3,14), (2,17) we can use the table to figure out what our equation will be

Notice on the table as you go on the y term from 8 to 11 to 14 to 17 you are having a constant rate of change of 3. So that’s your change in y

On the left side which is your x, you are going up by 1 every time because it’s {1,2,3,4} So your change in x is 1

Your slope or m in y=mx+b can be found by using the following formula

Change in y/change in x

So here our change in y is 3 and our change in x is 1. So that means our slope is

m=3/1 = 3

y=3x+b

To find b, you can plug in one of the points. Let’s use (1,8). So x=1 and y=8. Now we can plug these in and solve for b.

8=3(1)+b

8=3+b

Subtracting 3 on both sides we have

b=5

Therefore given y=3x+(b) we can plug b in to obtain the following equation

y=3x+5. So that’s your answer

Explain the difference between parallel and perpendicular lines in terms of their slopes. What form of equation of a line is easiest to determine slope?

Answers

Answer:

Parallel lines have the same slope, while perpendicular lines have completely opposite slopes. So a line has a slope of 2, a parallel line would have a slope of 2, and a perpendicular line would have a slope of -1/2. The easiest form to identify the slope is standard form because it shows the slope within the equation with out having to solve the equation or convert it into another form.
