2. French Vanitta K-Cups that originally
cost $5.99 are now on sale for $4.75.
Answer:
20.7% is the % decrease.
Step-by-step explanation:
If you are finding the % of decrease then see below.
% Decrease = (Original Cost - New Cost ) ÷ Original Cost × 100
5.99 - 4.75 = 1.24
1.24 ÷ 5.99 = .2070
.2070 × 100 = 20.7%
Sarah practices the piano 1/3 hour in the morning, 5/6 hour in the afternoon, and 4/5 hour in the evening.
Answer:

Here at Dillard 6-12 the amount of new teacher went from 24 teachers to 30 teachers. What is the percent of change?
Answer:
25% increase
Step-by-step explanation:
formula for percent of change = (new amount - original amount) / original amount; this will give you a decimal and multiply it by 100 to get the percent
(30 - 24) / 24
6/24 = 1/4 = 0.25
25% increase
A car covered a certain distance at a speed of 24 mph. While returning, the car covered the same distance at a speed of 16 mph. What was the average speed of the car for the entire journey?
Since the distances were the same you can find the average speed directly by adding the speeds then dividing by 2. No need to weight anything.
If we’re considering speed regardless of direction, the average speed is:
(24 + 16) / 2 = 40 / 2 = 20mph
However if direction matters, then one number has to be negative since the directions are opposite:
(24 - 16) / 2 = 8 / 2 = 4mph (in the positive direction)
Depending on the context, either of these could be your answer.
Answer:
19.2
Step-by-step explanation:
You have to trust me, this answer is correct. But here's my solution:
With the formula
Distance=Speed multiplied by Time, we can infer that Speed=Distance/Time.
But we only have one variable (Speed) in the two we need (Speed and Time), we have to pretend we have both variables. You can put the time as 1 hour, because that's the most basic unit. Note that this strategy will also work with 2 hours, 3 hours, or any measure of time.
So now for distance, let's see how fast a car can travel 24 miles. When going at 24 mph, then it'll take 1 hour. With 16 mph, then it'll take 1 hour and 30 minutes, so 1.5 or 3/2 hours.
Now we have the distance, which is 2 times 24 (Because the 24 mph and 16 mph both traveled 24 miles), equaling 48, and time, which is 1 hour plus 1.5 hours, which is 2.5 hours.
Now we use the formula Speed=Distance/Time, with 48/2.5=19 1/5 or 19.2

In which set do all of the values make the inequality 3k – 6 < 12 true?
The set of values that satisfies the inequality is (-∝, 6)
Inequality shows the non-equal comparison between two numbers or other mathematical expressions.
Given the inequality: 3k – 6 < 12
Solving the inequality:
3k – 6 < 12
Add 6 to both sides:
3k - 6 + 6 < 12 + 6
3k < 18
Divide both sides of the equation by 3:
3k/3 < 18/3
k < 6
The set of values that satisfies the inequality is (-∝, 6)

To solve for k in the inequality -16 -32 > -48, what steps are correct?:
A First, subtract 32 to each side, then divide by -16 and flip the sign
B First, divide both sides by 16, then add 32 to both sides and leave
the sign
C First, subtract 48 from both sides, divide by -16 and leave the sign
D First, add 32 to both sides, then divide by -16 and flip the sign
Answer:
D. First, add 32 to both sides, then divide by -16 and flip the sign
Step-by-step explanation:
Taking that the inequality is -16k-32>-48
First you have to get rid of any addition or subtraction, in this case you have to get rid of -32 by adding 32 to each side:
-16k-32+32 > -48 +32
Then you need to divide by -16 and flip the sign because you are dividing by a negative number and if you don't flip the sign the inequality will be false.

A large container holds 5 gallons of water. It begins leaking at a constant rate. After 15 minutes, the container has 2 gallons of water left. Part 1 At what rate is the water leaking? Express your answer as a positive value. 1 The water is leaking at the rate of gal/min. 5 Part 2 out of 2 How many minutes will it take for the container to go from full to empty? The container will be empty after minutes.
Answer:
.2 Gallons a minute
.2G/1m
25minutes until empty
Step-by-step explanation:
so the container lost 3 gallons in 15 minutes after that you changed it to how many minutes it took to lose 1 gallon by doing 15/3= 5
Now that you know 5/1 you divid 1/5 for an answer of 1/5 or .2 gallons a minute.
now you know that part two is easy
5/.2=25 which is the amount of times .2 gallon has to be removed from five and happens to also be the amount of minutes due to your solve from earlier.

The number of bottles she can fill if, Pam makes 5 liters of apple juice. She saves 0.5 liters of apples for dinner and puts the rest in bottles is 6.
What is multiplication?One of the four fundamental mathematical operations, along with addition, subtraction, and division, is multiplication. Multiply in mathematics refers to the continual addition of sets of identical sizes.
Given:
Pam makes 5 liters of apple juice. She saves 0.5 liters of apples for dinner and puts the rest in bottles,
If each bottle holds 0.75 liters,
Calculate the amount of juice left as shown below,
The amount of juice left = 5 - 0.5
The amount of juice left = 4.5 liter,
Calculate the number of bottles as shown below,
The number of bottles = The amount of juice left / juice held by each bottle
The number of bottle = 4.5 / 0.75
The number of bottles = 6

The cost of a baguette and a cup of hot chocolate is $1.45. The cost of 2 baguettes and a cup of hot chocolate is $2.10. What is the cost of one cup of hot chocolate?
Answer:
It is $0.8
Step-by-step explanation:
First find out the value of one baguette.
They just added one more baguette. So the amount left after subtracting them both will be the cost of 1 baguette.
2.10 - 1.45 = 0.65
Now, subtract the 1st cost with the cost of 1 baguette.
1.45 - 0.65 = $0.8
