edward deposited ​$7,500 into a savings account 5 years ago. The simple interest rate is 5​%. How much money did earn in​ interest?

Answers

Answer:

Edward earned $1,875 in interest.

Step-by-step explanation:

The formula for simple interest is i = prt, where p is the principal, r is the interest rate as a decimal fraction, and t is the time in years.

Here, p = $7,500, r = 0.05 and t = 5 years, and so the interest earned was

i = ($7,500)(0.05)(5) = $1,875.  

Edward earned $1,875 in interest.

will get brainliest To solve the system of linear equations 3 x minus 2 y = 4 and 9 x minus 6 y = 12 by using the linear combination method, Henry decided that he should first multiply the first equation by –3 and then add the two equations together to eliminate the x-terms. When he did so, he also eliminated the y-terms and got the equation 0 = 0, so he thought that the system of equations must have an infinite number of solutions. To check his answer, he graphed the equations 3 x minus 2 y = 4 and 9 x minus 6 y = 12 with his graphing calculator, but he could only see one line. Why is this? because the system of equations actually has only one solution because the system of equations actually has no solution because the graphs of the two equations overlap each other because the graph of one of the equations does not exist

Hello . Please help me with theses Negative exponents please and thank you.

Answers

Answer:

So, to work with negative exponents you need to multiply like a positive exponent, and move the decimal over double the digits place each time.

Examples:

If it is 4 with an exponent of -2, then you will multiply 4 by 4 to get 16, and then move the decimal over double the amount of digits. There are two digits, so you will move the decimal over four digits.

So the answer to 4 with an exponent of -2 would be .0016.

What angle has degrees over 180?
straight
reflex
right
acute

Answers

Answer:

Reflex

Step-by-step explanation:

I do not know what reflex is although by process of elimination reflex is the only answer left:

Straight is 180 degrees.

Right is 90 degrees.

Acute is an angle smaller than 90 degrees.

Reflex



Because every other on either has a 180 degree or lower so the answer is reflex

What is a fraction?

Fractions represent equal parts of a whole or a collection. Fraction of a whole is when we divide a whole into equal parts, each part is a fraction of the whole.

According to the given problem

On Monday Jeff makes a chocolate pie,

On Tuesday, he and his friends eat half of it, the remaining pie is, 1 - 1/2 = 1/2,

On Wednesday they eat one half of the remaining pie. i.e., they eat (1/2) ÷ 2 = 1/4 pie and the remaining pie is 1/4.

On Thursday, the remaining pie for Thursday is 1/4

Hence we can conclude that 1/4 of the pie was left on Thursday.
