I don't know what 90p means but basically, u have to multiply that by 3 and add it to our current total which is 13.
Then, u substract the total cost from the 20 and you should get the change.
if f(x) = 5x-20 find f(y+2)
Answer:
f(y + 2) = 5y - 10
Step-by-step explanation:
To evaluate f(y + 2), substitute x = y + 2 into f(x), that is
f(y + 2) = 5(y + 2) - 20
= 5y + 10 - 20
= 5y - 10

Can someone please check my answer for this function???
Answer:
You're wrong, it's the bottom left
Step-by-step explanation:
x^2-49 is a difference of squares so it factors into (x+7)(x-7) which obviously cancels out with the denominator leaving x-7 left. This is the line you should graph, but keep in that x+7 is still in the denominator so x cannot be equal to -7 which means that this point should be be on the line which leaves the answer to be the one on the bottom left.

Answer:
x^3-10x^2+x+120
Step-by-step explanation:
Assuming you mean roots -3, 5, 8
These happen when we have (x+3)(x-5)(x-8)=0
Expand this
(x^2-2x-15)(x-8)=0
=x^3-2x^2-15x-8x^2+16x+120

Answer:
i would help you but there is no table so, sorryStep-by-step explanation:
am goblin gimme ye pointsEnola is a waitress at a restaurant. Each day she works, Enola will make a guaranteed wage of $35, however the additional amount that Enola earns from tips depends on the number of tables she waits on that day. From past experiences, Enola noticed that she will get about $8 in tips for each table she waits on. How much would Enola expect to earn in a day on which she waits on 20 tables? How much expect to make in a day when waiting on t tables?
Answer:
1. 195
2. Y= 8t +35
Step-by-step explanation:
Answer:
$195; y=8t+35
Step-by-step explanation:
You can make an equation to find out how much Enola earns a day:
y=8t+35 ––This shows that "y" is the earnings for the day, "8t" represents $8 per table, and the "+35" represents the guarenteed $35 a day.
To answer the first question, the replace t with 20: y=8(20)+35
y=160+35
y=195
*For the second answer, I would put the equation because you do not know the number of tables because it is unspecified.
***You can change the "y" to whatever if you need to

On April 1, 1986, Casey deposited $1150 into a savings account paying 9.6% interest, compounded quarterly. If he hasn't made any additional deposits or withdrawals since then, and if the interest rate has stayed the same, in what year did his balance hit $2300, according to the rule of 72? A. 1993 B. 1992 C. 1994 D. 1991
In 1993 year his balance will hit $2300.
What is compound interest?The interest earned on savings that are computed using both the original principal and the interest accrued over time is known as compound interest. A = P(1 + r/n)^nt, where P is the principal balance, r is the interest rate, n is the number of times interest is compounded annually, and t is the number of years, is the formula for compound interest.
Given, On April 1, 1986, Casey deposited $1150 into a savings account paying 9.6% interest, compounded quarterly.
Here the given amount = $1150
Amount after getting compound interest in this amount = $ 2300
Since, $2300 is double to the amount $1150
According to the rule of 72, an amount is doubled if the product of annual rate and period (in years) is equal to 72. Also, with the help of this rule we get the approximate value of rate or time.
Since, Here the annual rate of interest = 9.6%
Let the given amount $1150 is doubled ($2300) in t years.
The, 9.6 × t = 72
⇒ t = 72/9.6 = 7.5
Since he deposited money on April 1 1986,
Thus, Her amount be $2300 on 1993
Therefore, In 1993 year his balance will hit $2300.

Write a percent proportion for the bar diagram
shown.
Answer:
If 68% is 17 then 100 percent is 25 I think
Step-by-step explanation:
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
68% = 17
100% = 25
The percent proportion for the bar diagrams are:
17and 25.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
There are two bar diagrams.
Blue bar diagram:
68% = 17
Red bar diagram:
68% = 17
Multiply both sides by 100/68.
100% = 100/68 x 17
100% = 25
Thus,
68% = 17
100% = 25

four and sixty eight thousandths in decimal form
Answer:
4.068
Step-by-step explanation:
( i think. I haven't done decimals in a while)
The value of each digit in a number is known as the place value. The four and sixty-eight thousandths in decimal form can be written as 4.068.
What is the place value of a digit in a number?The value of each digit in a number is known as the place value. The 5 in 350, for example, represents 5 tens, or 50, whereas the 5 in 5,006 represents 5 thousand, or 5,000. It is critical that children that while a digit can be the same, its value is determined by its position in the number.
Identification of the place value of a digit in a number:
The place values on the left of the decimal point start as ones, tens, hundreds, and so on.The place value on the right of the decimal point starts from the point and goes to the right as tenths, hundredths, and so onThe tens mean multiply by 10The tenth means the tenth part of that digit which is that digit divided by 10The given number can be written as,
Four → 4Sixty-eight thousandths → 68×(1/1000) = 68/1000 = 0.68Now, we can write the complete number as,
Four and sixty eight thousandths = 4 + 0.68 = 4.068
Hence, the four and sixty-eight thousandths in decimal form can be written as 4.068.

Juanita borrowed $600 to purchase a new computer. She was charged 7% interest for two years. She used the simple interest formula to find the interest.
I = 600(7)(2)
What error did Juanita make and how will her error affect the interest she calculates? Explain
{_____________________________
whoever does best get brainliest
Answer:
The correct formula should be I= 600(0.07)(2). Juanita made a very common error, she didn't put the percentage of interest in decimal form; or she didn't put the percent sign on it so we know to put it in decimal form. Her error will make a big difference; with using her calculations the answer would be $8,400. With the correct formula the answer is $84.
Hope this help! :)
Given :-
Juanita borrowed $600 .Rate of Interest = 7% .Time = 2yrs .To find :-
Error made by her.Answer :-
As we know that the formula for Simple interest is ,
SI = P*R*T / 100Substitute ,
I $600* 7 * 2 / 100 I = $ 84 .So here she did not write 7 % as 7/100 instead she wrote 7 .
