A group of friends share a large popcorn at the movies. It costs $3.15 to buy it and $0.85 for each refill. If they spent $7.40, how many times did the group of friends refill their popcorn?
Answer:
$2.6775
They refilled it 5 times
Step-by-step explanation:
Info we already know = . They shared a large popcorn
. It costs $3.15 to buy it and $0.85 for a refill
. They spend $7.40
3.15 x 0.85 = $2.6775
Explain: All you have to do is multiply 3.15 x 0.85 to get the answer, which is, $6.775. To check, you can do the inverse operation, which is, Division. So, with that being said, 2.6775 divided by 0.85 = $3.15.
I just explained so you can have a better understanding!
Answer:
They refilled their popcorn 5 times.
Step-by-step explanation:
First, set up an equation.
y = mx + b
y is the total money spent
m is the cost for each refill
x is the amount of times the popcorn is refilled
b is the start price / the price to buy the popcorn
7.40 = (0.85)x + 3.15
To solve for x, first subtract 3.15 from both sides.
4.25 = 0.85x
Now to isolate x, divide both sides by 0.85.
x = 5
They refilled their popcorn 5 times.
Before moving on, check your answer by plugging in x = 5 into the original equation.
7.40 = (0.85)(5) + 3.15
7.40 = 4.25 + 3.15
7.40 = 7.40
Your answer is correct.

You pick a card at random, put it back, and then pick another card at random.
6, 7, 8, 9.
What is the probability of picking a 9 and then picking a number greater than 7?
Write your answer as a percentage.
Answer:
12.5%
Step-by-step explanation:
There are 4 cards to choose from in the beginning.
Pick 9 out of the 4.
p(9) = 1/4
You put the card back. Now there are again 4 cards.
There are 2 numbers greater than 7: 8 and 9.
p(8 or 9) = 2/4 = 1/2
p(9 then number greater than 7) = 1/4 × 1/2 = 1/8
1/8 = x/100
8x = 100
x = 100/8
x = 12.5%
Answer: 12.5%

A number is increased by 20%. Work out the original number of the increase is 600
Answer:
The answer would be 480
Step-by-step explanation:
The first step is to find out 20% of 600 and that would equal 120, the next step is to subtract 120 from 600 and the answer is 480.
Answer:
480
Step-by-step explanation:
If the number increased by 20% we can decrease it by 20% to get our number before it was increased.
20% of 600 is 120
600-120=480

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
What is the quotient?
When two numbers are divided by each other, the result is a quotient. For instance, when we divide 6 by 3, the result is 2, which is the quotient. An integer or a decimal number can be the quotient. We have an integer as the quotient for precise divisions, like 10 5 = 2, and a decimal for erroneous divisions, like 12 5 = 2.4.

Answer:
121.2 cm^2
Step-by-step explanation:
Surface area:
6 x 5.5 x 2 = 6 x 11 = 66 cm^2
6 x 2.4 x 2 = 12 x 2.4 = 28.8 cm^2
5.5 x 2.4 x 2 = 11 x 2.4 = 26.4 cm^2
Total surface area = 66 + 28.8 + 26.4 = 94.8+ 26.4 = 121.2 cm^2

A store regularly sells a Nintendo Switch Lite for $200. They are currently on sale for 30% off and in your state the sales tax is 8%. What would be the final cost for the consumer (including tax) if they buy the Nintendo Switch Lite?
Answer:
$151.20
Step-by-step explanation:
The sale price of the Nintendo Switch Lite is 30% off its regular price of $200, which means the discount is:
Discount = 30% x $200 = $60
The sale price of the Nintendo Switch Lite after the discount is:
Sale price = $200 - $60 = $140
The sales tax in the state is 8%, so the tax amount on the sale price is:
Tax amount = 8% x $140 = $11.20
Therefore, the final cost for the consumer, including tax, would be:
Final cost = Sale price + Tax amount = $140 + $11.20 = $151.20
Hence, the final cost for the consumer, including tax, would be $151.20 if they buy the Nintendo Switch Lite.

Step-by-step explanation:
Pls help! Will give brainliest!!
Considering area (A) of garden as 30 square feet:
30 = x(2x+7)
Now we need to expand it:
x(2x+7) = 2x^2 + 7x
2x^2 + 7x = 30
Adding this into an Algebra calculator gives us 5/2 or 2.5
So x = 2.5
To prove this:
2(2.5) + 7 = 12
14 * 2.5 = 30
simplify -6/5 divided by 2 2/5
Answer:
0.24or -1/2
Step-by-step explanation:
The simplified fraction of -6/5 divided by 2 2/5 is -1/2.
To simplify the expression -6/5 divided by 2 2/5.
First, let's convert the mixed numbers to improper fractions:
2 2/5 = (2 x 5 + 2) / 5
= 12/5
Now, we can rewrite the expression as:
-6/5 ÷ 12/5
When dividing fractions, we can multiply by the reciprocal of the second fraction. So, we have:
= -6/5 x 5/12
= -6/1 x 1/12
Multiply the numerators and denominators:
= (-6 x 1) / (1 x 12)
= -6/12
= -1/2
Therefore, the simplified fraction of -6/5 divided by 2 2/5 is -1/2.

And pls don’t answer if you don’t know it.
Answer:
Possible outcomes: 1a 1b 2a 2b 3a 3b
Outcomes for spinning a one = 2
1a, and 1b 2/6
Outcomes for spinning an "a" = 3
1a, 2a, and 3a.
1a is already in the first set so we can exclude it. 2/6
2/6+2/6=4/6
There is a 4/6 or 2/3 chance of getting either an a or an 1
Answer:
(d) 1A, 1B, 2A, 2B, 3A, 3B
(e) 2/3 or 66.66% chance
Explanation is below
Step-by-step explanation:
(d) The Total outcomes are 3*2 = 6, because there are 3 numbers and 2 letters.
The outcomes are:
1A
1B
2A
2B
3A
3B
(e) Of the 6 outcomes, 3 of them have A and 2 of them have 1. But one of them has an A and 1, so it is 4 outcomes: 1A, 1B, 2A, and 3A.
So it is 4/6 = 2/3, or 66.66...% chance

HELP
Jodi bought a new car with a 14-gallon gas tank. Around town she is able to drive 336 miles on one tank of gas. On her first trip traveling on highways, she drove 448 miles on one tank of gas.
a) Write a compound inequality that represents how many miles Jodi can drive on a tank of gas. Let m represent the number of miles per gallon.
b) Rewrite the compound inequality as two simple inequalities separated by either "and" or "or".
c) Solve each simple inequality. Then write the solution in compact form.
d) Explain your solution in terms of the problem situation.
g) represent the solution on a number line. Describe the shaded region in terms of the problem situation.
Part A:
Answer:
\(336\leq 14m\leq 448\)
Step-by-step explanation:
Step 1:
Jodi bought a new car with a 14-gallon gas tank.
Around town, she can drive 336 miles on one tank of gas.
She drove 448 miles on one tank on a trip on the highway
m will represent the number of miles per gallon of gas.
Step 2:
If m represents the number of miles per gallon of gas she gets and her tank holds 14 gallons then 14m represents the number of miles she can drive.
14 gallons · \(\frac{m}{1} = 14m\)
Around town, she was able to drive 336 miles and on the highway, she was able to drive 448
So... \(336\leq 14m\leq 48\)
Part B:
Answer:
The compound inequality is two simple inequalities separated by "and" is \(336\leq 14m\) and \(14m < 448\).
Step-by-step explanation:
Step 1:
We are told Jodi bought a new car with a 14-gallon gas tank.
Around town, she can drive 336 miles on one tank of gas. She drove 448 miles on one tank of gas on her first trip traveling on highways
Here we need to rewrite the compound inequality
Let \(m\) represent the number of miles per gallon of gas.
Step 2:
Since \(14m\) must greater than or equal to \(336\) and less than or equal to \(448\):
The two simple inequalities must be separated by the word "and"
\(336\leq 14m\) and \(14m<448\)
Part C:
Answer:
The solution of simple inequality is \(24\leq m\) and \(m\leq 32\)
Step- by step explanation:
Step 1:
We are given Jodi bought a new car with a 14-gallon gas tank. Around town, she can drive 336 miles on one tank of gas. She drove 448 miles on one tank of gas on her first trip traveling on highways.
Step 2:
Solve each simple inequality by dividing both sides by 14:
\(336\leq 14m\) and \(14m\leq 448\)
\(\frac{336}{14}\leq \frac{14m}{14}\) and \(\frac{14m}{14} \leq \frac{448}{14}\)
\(24\leq m\) and \(m\leq 32\)
Part D:
Answer:
The solution of the compound inequality is \(24\leq m\leq 32\)
Step 1:
We are given Jodi bought a new car with a 14-gallon gas tank. Around town, she can drive336miles on one tank of gas. She drove 448 miles on one tank of gas on her first trip traveling on highways. To solve the compound inequality without rewriting it as two simple inequalities
Step 2:
Solving compound \(336\leq 14m\leq 448\) for \(m\) by dividing all sides by 14
\(226\leq 14m\leq 448\\\)
\(\frac{336}{14}\leq \frac{14m}{14} \leq \frac{448}{14}\)
\(24\leq m\leq 32\)
