A. Sarah's bill at the restaurant was $12.81. She left a tip of 20%. What was the tip amount? Round your answer to the nearest hundredth.
B. What was the total bill? Round your answer to the nearest hundredth.

Answers

Answer:

A. $2.56

B. $15.37

Step-by-step explanation:

A. When you’re asking what is a certain percent of a specific number, you turn the percent into a decimal and multiply it by the specific number. In this case, 0.20 * 12.81 = 2.562

Since we are to round to the nearest hundred, that leaves us with $2.56.

B. To get the total bill, add 12.81 and 2.56 to get a total of $15.37.

A : 2.56 reason: 12.81 x 1/5 is 2.56
B add them together you get 15.37
you round them to hundredths

First of all, you want the distance before the gas stop, so you need to subtract the 65 1/4 miles by the total since you don’t need that, which is
306 3/4 miles.

Since you wanna work backwards to find the answer, you have to divide by 3 since, just like the first part, you want the distance of the first part of the road trip, not the other parts (if that makes sense).

306 3/4 divided by 3 is your answer, which is

102 1/4 miles

Answers

-32xy-25 try dat anyways have a nice dayyyy byeeeee

Step-by-step explanation:

i believe what you need help on is simplifying the equations. so let's start with the first one.

====================================================================

(2x+1)(x+5) original problem

(2x)(x)+(2x)(5)+(1)(x)+(1)(5) we can break this down into smaller pieces so we know what we're dealing with in this equation.

2x2+10x+x+5 if we break this down a little more and add some bracket numbers, this is what we get.

2x2+11x+5 this is the most simplified equation.

====================================================================

6x−4xy original problem.

unlike the last problem, we can easily just... 6x + (−4xy).

−4xy+6x this is the most simplified equation.

====================================================================

ok, the last one. phew!

unfortunately, 16x^2-25 is actually the simplest it can get. so, let's try factoring.

if we factored, we would get...

(4x+5)(4x−5)

===================================================================

the serving size for a toddlers daily vitamin c is 3/4 cup of orange juice. if there are 2 1/4
cups of orange juice how many servings of vitamin c are there for a toddler

Answers

Three servings
To find the number of servings we need to determine how many sets of 3/4 there are in 2 1/4 .
2 1/4 divided by 2 (4) + 1 = 1/4= 4/1 = 4 which will equal 9/4
9/4 divided by 3/4= 9/4 x 4/3 =9/3= 3 servings

Answer:

Three servings

To find the number of servings we need to determine how many sets of 3/4 there are in 2 1/4 .

2 1/4 divided by 2 (4) + 1 = 1/4= 4/1 = 4 which will equal 9/4

9/4 divided by 3/4= 9/4 x 4/3 =9/3= 3 servings

It is 3/2 and 2/3 this is because it is. I think this is amazing and cool

Answer:

3/2 and 3/4

Step-by-step explanation:

First, we need to know: what is a decimal that terminates?

A decimal that terminates is a decimal that has an end

For ex: 1/4 = 0.25

The decimal won't go on and on, it ends with only a few digits

Here's an example of one that doesn't terminate:

1/3 = 0.3333333333333333333333333333333333 . . . . . and so on

With this knowledge, we can look at the fractions in your problem: 3/2, 2/3, 3/4, and 5/7

To find the decimals, divide the numerator by the denominator, you get:

1.5, 0.66666666 . . ., 0.75, and 0.71428571428 . .,

We can see that the first and third don't run on, while the second and last do.

Therefore, your answer would be 3/2 and 3/4
