The regular price of a pair of shoes is $125. What is the discount price?

Answers

Answer:

$93.75

Step-by-step explanation:

First step, we need to find 25% of 125, we can do this by multiplying .25 by 125. This leaves us with $31.25. Now, we subtract 31.25 from 125, this leaves us with $93.75. There is your answer. Another way to do this is to find 75% of 125 because 25+75 equals 100.

93.75!!!!!!!!!!!!!!!!!!!

Is x = 3 a solution to the equation x + 7 = 11?

Answers

Answer:

A

Step-by-step explanation:

3+7 is 10, not 11. Therefore, x cannot be 3.

Answer:

The correct answer is A. No, because 3 + 7 = 11 is not true.

Step-by-step explanation:

Just like the answer says, if x =3, then that would mean that 3 + 7 = 11. Since

3 + 7 =10, this statement is not true.

Therefore, the correct answer is A.

Hope this helps! :D

In two or more complete sentences, explain the theorem used in solving for the range of possible lengths of the third side, AB of ABC.

Answers

Answer:

Step-by-step explanation:

You can use the Pythagorean Theorem to find the length of the third side AB (Identified as "x" in the figure attached in the problem), which says that in a right angled triangle, the square of the hypotenuse is equal to the sum of the squares of the legs:

a² = b²+c²

As we can see the figure, the triangle does not have an angle of 90°, but it can be divided into two equal parts, leaving two triangles with a right angle. We already have the values of the hypotenuse and a leg in triangle "A" , so we can find the value of the other leg:

b = √(a²-c²) b = √(10²-4²) b = 9.16

With these values, we can find the hypotenuse in the triangle "B": x = √b²+c² x = √(9.16)²+(4)² x = 10

Jeremy opened a bank account depositing $1,950 initially. He withdraws a fixed amount every month. At the end of the first month, account balance is $1,800. Which equation could model the situation?

Answers

Answer:

1800 = 1950 - m

Step-by-step explanation:

Lets call the fixed amount he withdraws every month m. He starts with $1950 and withdraws a certain amount, m, every month. At the end of the first month, he has withdrawn 1m amount of money and ends up with $1800. Therefore, 1950 - 1m =  1800. We can get rid of the 1 and get 1950 - m =  1800, or 1800 = 1950 - m. If the answer choices do not have "m" as a variable, you can substitute "m" for any variable.
