PLEASE HELP THIS IS ON A TEST AND I DON'T PAY ATTENTION Paul received an estimate of $75,000 for an inground pool. After the job was completed, it cost him $93,000. Express the error in this estimate as a percentage.
A.24% error
B.19% error
C.81% error
D.33.3% error

Answers

Answer 1

Answer:24% error

Step-by-step explanation:

subtract the estimate and the cost

93,000-75,000

=18000

divide the cost and the subtracted sum you just got

=[tex]\frac{18000}{75000}[/tex]

cross out the common factor

=[tex]\frac{6}{25}[/tex]

Multiply a number to both the numerator and denominator (easier if you multiply the number that makes the denominator 100)

[tex]\frac{6}{25} x\frac{4}{4}[/tex]

=[tex]\frac{24}{100}[/tex]

write the fraction as a percentage

=24%

Hope this helps! Good luck!

Dont worry I used to not pay attention as well

A cyclist rode 10.15 miles in 0.7 hours.



a) How fast was the cyclist going in miles per hour?

miles per hour

b) At that rate, how long will it take the cyclist to go 11.6 miles (in hours)?

hours

Answers

Answer:

A: 14.5

Step-by-step explanation:

If you divide 10.15 with 0.7 you get 14.5 but for B I am not sure yet so if someone else can figure it out that can help you out.

It should be 11.6 x .7 / 10.15 = .8hrs

HELP?!!!! ITS A A AND B QUESTION

Answers

Answer:

A: 80 and B: 5.5

Step-by-step explanation:

For A, just multiply 20 and 4 and which you would get 80 miles. And for B, if 1 inch is equal to 20 miles, you can divide 110 and 20 but the answer will be 5.5 rather than 5.

Write down in terms of n, an expression for the nth term of the following sequence b) -7 -12 -17 -22 -27

Answers

Answer:

If you were taught that the first element in the sequence is at n = 0:

-7 - 5n

If you were taught that the first element is at n = 1:

-2 -5n

Step-by-step explanation:

First, find a pattern in the elements of the sequence. At first glace, I notice that each consecutive number is the previous number minus 5.

Thus it can be seen that for each consecutive number in the sequence, 5 is subtracted from negative 2 n times! Therefore, the expression must be:

-2 - 5n

Let's double check the expression! When n = 3, it should equal -17.

-2 - 5(3) = -17

And when n = 5, it should be -27:

-2 - 5(5) = -27.

This is the case if the first element in your sequence is n = 1, if you've been taught that the first element is n = 0, the expression would be:

-7 - 5n

If the difference between X-4/3 and 2(x+5)/4 is two
What is x?

Answers

Answer: x = 10

Step-by-step explanation: To find the value of x, we can start by isolating x on one side of the equation. To do this, we can first subtract 2(x+5)/4 from both sides of the equation:

X-4/3 - 2(x+5)/4 = 2

We can then multiply both sides of the equation by 12 to clear the denominators:

4x - 16 = 24

Now we can add 16 to both sides of the equation:

4x = 40

Finally, we can divide both sides of the equation by 4 to solve for x:

x = 10

Therefore, the value of x is 10.

similarities between parallelogram, and trapezoid

Answers

Answer:

A trapezoid has one pair of parallel sides and a parallelogram has two pairs of parallel sides. So a parallelogram is also a trapezoid.

Answer:

Both a parallelogram and a trapezoid have four sides and four angles. Both shapes have opposite sides that are parallel to each other. The main difference between the two shapes is that in a parallelogram, opposite sides are equal in length, while in a trapezoid, only the two parallel sides are equal in length.

What is 3/20 as a simplified fraction?

Answers

Answer:  The fraction is already in simplest form

Step-by-step explanation:

The given fraction is already in its simpliest form.

To simplify the fraction 3/20, we need to find the greatest common factor (GCF) of the numerator and the denominator and divide both by that factor.

The factors of 3 are 1 and 3, while the factors of 20 are 1, 2, 4, 5, 10, and 20. The greatest common factor of 3 and 20 is 1, as that is the largest number that divides evenly into both.

Dividing both the numerator and denominator by 1, we get:

(3 ÷ 1) / (20 ÷ 1) = 3/20

Since the GCF is 1 and there are no other common factors, the fraction 3/20 is already in its simplified form.

each molecule of water contains 2 hydrogen atoms and 1 oxygen atom. complete the table. is the number of hydrogen atoms a function of the number of oxygen atoms?explain.​

Answers

Answer:

Number of Oxygen atoms         Number of Hydrogen atoms

1                                                  2

2                                                  4

3                                                  6

4                                                  8

The number of hydrogen atoms is not a function of the number of oxygen atoms. This is because the number of hydrogen atoms in a molecule of water is always twice the number of oxygen atoms. This relationship is defined by the chemical formula of water, which is H2O. Therefore, the number of hydrogen atoms is a fixed value and it doesn't change based on the number of oxygen atoms.

2. Lonzo opened a bank account that earns 1.2% simple interest each year. After 7 years, Lonzo will earn $126 in interest. How much did Lonzo deposit when he opened the account?​

Answers

Answer:   1500 dollars

===========================================

Work Shown:

i = P*r*t

126 = P*0.012*7

126 = P*0.084

P = 126/0.084

P = 1500 dollars

----------------

Explanation:

i = interestP = deposit amountr = 0.012 is the decimal form of the 1.2% interest ratet = number of years

Make sure you use the decimal form of r, and not the percent form.

Answer:

$116.24

Step-by-step explanation:

the simple interest formula is A = P(1 + rt), where A is the final amount, P is the initial amount, r is the interest rate in decimal form, and t is the amount of time in years.

we can plug in the values from the problem and set up this equation:

126 = P(1 + 0.012(7))

simplify and isolate P to get:

[tex]P=\frac{126}{1+0.012(7)}[/tex]

now, we simplify further to get our answer:

P = 116.24

The baker made a batch of chocolate chip, oatmeal raisin, and sugar cookies. If P(chocolate chip) = 68%, interpret the likelihood of randomly selecting a chocolate chip cookie from the batch.

Likely
Unlikely
Equally likely and unlikely
This value is not possible to represent probability of a chance event.

Answers

Answer:

a) Likely

Step-by-step explanation:

The probability of an event is a measure of the likelihood of that event occurring. In this case, P(chocolate chip) = 68% means that there is a 68% chance of randomly selecting a chocolate chip cookie from the batch. A probability of 68% is considered a relatively high probability, making it likely that a chocolate chip cookie will be selected.

the answer will be likely because there is a 68% percent chance out of 100% to choose a chocalte chip cookie, and the other cookies only have a 16% chance
