Answer:
[tex]\frac{612}{999}[/tex]
Step-by-step explanation:
To convert repeating decimals to fractions, you take the numbers that are repeating, in this case 612, and you see how many numbers are repeating. Here we have 3 numbers repeating and so you would divide 612 by 3 9's meaning 999. So 0.612 repeating is equal to [tex]\frac{612}{999}[/tex]. To make sure the answer is right, you can divide the numbers in a calculator to make sure you get the correct decimal.

Step-by-step explanation:
Step 1: Define Equation
2t + 5 = 2t + 5
Step 2: Solve for t
Subtract 5 on both sides: 2t = 2tDivide 2 on both sides: t = tHere we see that t does indeed equal t.
∴ t = infinite amount of solutions
I need help on a math problem on my homework
Answer: Where is the question?
Step-by-step explanation:
Lana correctly answered 48 of 60 questions on a math exam. What percent of questions did she answer correctly?
Answer:
I think it roughly 66.67%
Step-by-step explanation:
sorry if I'm no help
The percent of questions she answered correctly is 80%.
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Given;
Lana correctly answered 48 of 60 questions on a math exam
Now,
=48*100/60
=480/60
=80
Therefore, the percentage will be 80%.

HELPP WITHH MATHHH PLEASE SMART PEOPLE
Answer:
is not; 4t
Step-by-step explanation:
Because when you switch the signs for substraction like 2-3 you will get -1, but if you do 3-2, then youll get 1. The Same goes for this question. If you plug in 2 for t, like 13(2)-4(2), it will be 26-8, which is 18. But if you do the same for the other equation, 4(2)-13(2), you will get 8-26, which equals -18. So -18 does not equal 18 because one postive and the other is negative.
Answer:
is not; -4t
Step-by-step explanation:
It's not the same because the negative sign always belongs to the number in front of it.

Answer:
5 gallons per fish
Step-by-step explanation:
Your first answer is correct because anytime a line passes through the origin, it is proportional.
To find the number of gallons per fish, we can take the first point which is (2, 10) and divide it by 2; (2÷2, 10÷2) = (1, 5)
This means that for every fish you get, you will need 5 gallons of water to meet the requirement.

Which will have a higher effective interest rate - a payday loan for $1500 that
is due in 12 days with a fee of $90, or a payday loan for $1500 that is due in
10 days with a fee of $90?
A. A payday loan for $1500 that is due in 12 days with a fee of $90,
since it has the shorter period
B. A payday loan for $1500 that is due in 10 days with a fee of $90,
since it has the shorter period
C. A payday loan for $1500 that is due in 10 days with a fee of $90.
since it has the longer period
D. A payday loan for $1500 that is due in 12 days with a fee of $90,
since it has the longer period
Answer:
B. A payday loan for $1500 that is due in 10 days with a fee of $90, since it has the shorter period
The higher effective interest rate is for A payday loan for $1500 that is due in 10 days with a fee of $90, since it has the shorter period, the correct option is B.
What is Interest Rate?Interest Rate is the rate at which a person either takes loan, or a person lends money to somebody.
The interest rate is different for different types of loans, some interest are simply calculated on the principal, called as Simple Interest while some are calculated on both the principal and the interest, called as Compound Interest.
A payday loan has principal of $1500
It is due in 12 days, so time period is 12 days.
The interest amount is $90
I = P * R *T / 100
90 = 1500 *12 *R /100
R = 0.5 %
A payday loan has principal of $1500
It is due in 10 days, so time period is 10 days.
The interest amount is $90
90 = 1500 *10 *R /100
R = 0.6 %
The rate of interest is more for a payday loan for $1500 that is due in
10 days with a fee of $90.
