A store is having a sale on apples. The apples are normally $3.00 per pound, they are currently 20% off. What is the new price of the apples?
Answer:
2.40$ dollars.
We find 20% of 3.00$, which is 0.6$ we then subtract that amount by the normal cost which is 3.00$, so we have an equation that looks like this 3.00$ - 0.6$ = 2.40$ dollars.
Caleb throws a ball three times for his dog Leo. For each throw, Leo either
catches the ball or misses it. Identify the sample space (the correct list of
possible outcomes) for the results.
C = catch, M = miss
The notation CMC means Leo caught the first ball, missed the second one,
and caught the third one.
A. {CCCC, CCMM, MMMM}
B. {CCC, CCM, CMC, MCC, MMC, MCM, CMM, MMM}
C. {CCC, CMC, MMM}
D. {CC, CM, MC, MM}
Answer:
B {CCC, CCM, CMC, MCC, MMC, MCM, CMM, MMM}
Step-by-step explanation:
Ima try to explain this in the process of elimination:
A isn't right since he only throws the ball 3 times
C isn't right, since he could catch it, miss, then catch again and would still match the criteria stated.
D Isn't right since he threw it 3 times, not twice
that only leaved B to be correct! Hope this helps!

The circle graph shows how Lila spent her after-school time during the month of October.
Part A
If Lila spent a total of 50 hours on these activities in the month of October. How much time did she spent at Yoga?
Answer:
14 hours
Step-by-step explanation:
percent of a number
28% of 50
(OR, there is another way)
you could switch it and do 50% of 28, either way you get the same answer.
50% of 28 is 14.
***if there is any percent problem where it is something like 22% of 100 or 78% of 50, you can flip it to say 100% of 22 or 50% of 78.

Which key correctly represents the information below?
A) 11 | 2 = 12
B) 1 | 2 = 12
C) 11 | 2 = 112
D) 11 | 2 = 13
Answer:
The correct answer is C) 11 | 2 = 112
Step-by-step explanation:
That is because that is how these kinds of stem and leaf plots work. You add the number on the left to each individual number of the right. For example, the numbers in row 11 are actually:
112, 112, 115, 118.
The reason why we have stem plots is that it removes the need to write the 11 at the beginning of the number and lets you interpret and analyze the data more easily.
Stemplots are also pretty annoying and useless, and something you'll basically never use, so don't worry if they don't make much sense :)

A math class is having a discussion on how to determine if the expressions 4 x minus x + 5 and 8 minus 3 x minus 3 are equivalent using substitution. The class has suggested four different methods.
Which describes the correct method?
*Both expressions should be evaluated with one value. If the final values of the expressions are both positive, then the two expressions must be equivalent.
*Both expressions should be evaluated with one value. If the final values of the expressions are the same, then the two expressions must be equivalent.
*Both expressions should be evaluated with two different values. If for each substituted value, the final values of the expressions are positive, then the two expressions must be equivalent.
*Both expressions should be evaluated with two different values. If for each substituted value, the final values of the expressions are the same, then the two expressions must be equivalent.
Answer:
Both expressions should be evaluated with one value. If the final values of the expressions are the same, then the two expressions must be equivalent.

Ms. Leeper gives her sixth- and seventh-grade students a geography test to decide who will represent her class in the school geography bee. The line plots below show the results of the test for her sixth-grade class and seventh-grade class, respectively.
The data for each grade have the same interquartile range (IQR). Which of the following best compares the two test score distributions?
A - The median score of the seventh-grade class is 2 points greater than the median score of the sixth-grade class. This difference is the same as the IQR.
B - The median score of the seventh-grade class is 2 points greater than the median score of the sixth-grade class. This difference is twice as much as the IQR.
C - The median score of the seventh-grade class is 3 points greater than the median score of the sixth-grade class. This difference is the same as the IQR.
D - The median score of the seventh-grade class is 3 points greater than the median score of the sixth-grade class. This difference is twice as much as the IQR.
a bag of jellybeans has 20 watermelons jellybeans, 45 sour apple jellybeans, 30 orange jellybeans and 5 cotton candy jellybeans. if you reach in and grab one jellybean, what is the probability that it will be watermelon flavored
help fast pls 7th grade
The probability that it will be watermelon flavored is -
P{E} = 1/5.
What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is a bag of jellybeans has 20 watermelons jellybeans, 45 sour apple jellybeans, 30 orange jellybeans and 5 cotton candy jellybeans.
We can write the probability as -
P{E} = (20)/(20 + 45 + 30 + 5)
P{E} = 20/100
P{E} = 1/5
Therefore, the probability that it will be watermelon flavored is -
P{E} = 1/5.

You and your friends went to UNO's for dinner (way back in 2019). Together the total bill for your meals was $40. You have a 15%-off coupon for the meal! Then, after the discount, a 7% sales tax is applied. What is the final price, after the discount and the tax, that you are your friends have to pay for the meal?
Answer:
$36.38
Step by step explanation:
First, we need to find out what 1% of $40 dollars is. To do this, we divide 40 by 100.
This gives us $0.40.
To then find out fifteen percent of $40, you then times $0.40 by 15.
This gives us 6 dollars.
Now, to work out the discount, we take 6 from 40.
$40 - $6 = $34
Now we have to work out the tax.
Again, we have to work out what 1% of $34 is.
This gives us $0.34
Then times that by 7 to find 7%
0.34 x 7 = $2.38
Since this is tax we have to add instead of subtracting.
$34 + $2.38 = $36.38 as the final bill.

solve for x: 3 x - s = r
Answer:
Brainliest please
Step-by-step explanation:
Simplifying
3x + -1s = r
Reorder the terms:
-1s + 3x = r
Solving
-1s + 3x = r
Solving for variable 's'.
Move all terms containing s to the left, all other terms to the right.
Add '-3x' to each side of the equation.
-1s + 3x + -3x = r + -3x
Combine like terms: 3x + -3x = 0
-1s + 0 = r + -3x
-1s = r + -3x
Divide each side by '-1'.
s = -1r + 3x
Simplifying
s = -1r + 3x
Find the unknown lengths

Brad paid for a book that cost $13.40 with a $20 bill. What is the least combination of coins and bills that can be used to make his change? What are two other different combinations of coins and bills that can be used to make the change?
Answer:
First combination: One $5 bill, one $1 bill, two quarters and one dime.
Second combination: One $5 bill, one $1 bill, two quarters and two nickles.
Step-by-step explanation:
I highly suggest reading it to make sure you understand it
Okay so for this one you're going to want to do 20.00-13.40. The answer to that is 6.60
So we have to work with $6.60
Now lets think of the obvious/easiest.
A $5 bill is going to be our best friend in this.
We have to do
6.60-5.00=x
(Don't freak out about x, it's just our place marker!!)
The reason we do 5.00 is because that's what $5 is.
So let's solve now.
6.60-5.00=1.60
So x=1.60
But you don't have to worry about x, I'm just explaining it from before.
So we have to keep in mind that we used one $5 bill. Now let's use one $1 dollar bill.
1.60-1.00=0.60
So now we only have to figure out how to get 60 cents from any of the coins.
A quarter is 25 cents so lets use two of those
25+25=50
60=50=10
Lets recap on everything we've used so far.
We've used one $5 bill, one $1 bill, and two quarters.
Now we're going to add a dime to the mix.
A dime is worth 10 cents.
So for the first combination we used: One $5 bill, one $1 bill, two quarters and one dime.
Now our second combination is going to be really easy.
We can use almost everything the exact same, we're only going to switch up the dime part.
1 dime = 2 nickles
Nickles are worth 5 cents
So we take out the dime and replace it with two nickles.
So for the second combination we use: One $5 bill, one $1 bill, two quarters and two nickles.
