A restaurant bill is $25, and a 20 percent tip should be given to the waiter. Which expression can be used to find the total amount that will be paid?
25 dollars times 0.02
25 dollars times 0.20
25 dollars times 1.20
25 dollars times 2.00
Answer:
B. 25 dollars times 0.20
Step-by-step explanation:
When finding the percentage, you shift the percentage you want two places to the right. In our case we have 20.00, so shifting the 20 two places to the right would give us 0.20.

The first step when adding or subtracting rational expression with unlike denominator is to
To add or subtract rational expressions with unlike denominators, first find the LCM of the denominator. The LCM of the denominators of fraction or rational expressions is also called least common denominator, or LCD. Write each expression using the LCD.
Adding or subtracting rational expressions is remarkably similar to adding and subtracting fractions, since a rational expression is a fraction.
The operations are the same.
When adding or subtracting fractions with unlike denominators, we multiply the denominator of one fraction times the denominator of the other fraction, and then alter the numerators.
The process with rational expressions is the same.
So the first step is to make sure both rational expressions have the same denominator.

ebrant spends $76 in a gift shop. This is 80% of the money he planned to
spend in the gift shop. How much money, in dollars, did Mr. Hildebrant plan to
spend in the gift shop?
Answer:
Mr. Hildebrant planned to spend $95 in the gift shop.
Step-by-step explanation:
We want to find 80% of $? equals $76.
We can write an equation to help us solve for x, the money that Mr. Hildebrant planned to spend in the gift shop.
.80x = 76Divide both sides of the equation by .80.
x = 95Mr. Hildebrant planned to spend $95 in the gift shop.

Which inequality statement describes the two numbers: - 22 and a number 47 units to the right of -22?
A)
-22 > 47
B)
-22 < 47
C)
-22 > 25
D)
-22 < 25
Answer:
D) -22 < 25
Step-by-step explanation:
If the number is 47 units to the right, then the number will be larger than -22, because negative values get larger the closer they are to zero.
47 units right from -22 is the same as: -22 + 47, which equals 25.
So, we can conclude that -22 < 25 is the inequality.

The diameter of a circle is 100 cm. What is the circumference of the circle? (Use 3. 14 for π. )
Explanation:
Use the formula C = pi*d
We're multiplying 3.14 by the diameter 100 to get 314, which is the approximate distance around the circle (aka perimeter). The value is approximate because pi = 3.14 is approximate.

Does anyone know the correct equation?
Purchasing the correctly sized BMX bike is based on the height of the rider. In order to fit a customer, the salesman can use the equation b=0.29h+1.35 where b is the size of the BMX bike frame in inches and h is the height of the rider in inches.
Answer:
(a) 1 inch of rider ⇒ 0.29 inches of frame
Step-by-step explanation:
The "slope" in the equation is the coefficient of the independent variable. Here, that variable is "h", and its coefficient is 0.29. That is, the height of the rider is multiplied by 0.29 (and a constant is added) in order to find the height of the frame.
__
The meaning of the value 0.29 is that a 1 inch increase in the rider's height should result in a 0.29 inch increase in the height of the frame of the bike.
The question asks for an explanation of the slope, not its function in the equation. That is why we have chosen the first answer.
Answer: inch of rider ⇒ 0.29 inches of frame
