An equation is formed of two equal expressions. The constant of proportionality between the number of cups of coffee and the total bill amount is 2.50.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Given that a cup of coffee cost $2.50. Now, if the total cost of coffees is $22.50, then the number of cups of coffee that was purchased is,
Number of cups of coffee = Total bill amount / Cost of a coffee
Number of cups of coffee = $22.50 / $2..50
Number of cups of coffee = 9
A.) An equation for the total bill amount, y and total number of cups of coffee, x can be written as,
Total bill amount = Cost of a coffee × Number of cups of coffee
y = 2.50 × x
y = 2.50x
B.) The constant of proportionality between the number of cups of coffee and the total bill amount is 2.50.

A cooler contains 12 bottles of apple juice and 18 bottles of orange juice. You reach into the cooler without looking and pull out one bottle of apple juice. Then you reach into cooler and pull out another bottle of juice. What is the probability of pulling apple juice and then pulling another apple juice?
Answer:
P = 0.232
Step-by-step explanation:
In the cooler, we have 12 bottles of apple juice and 18 bottles of orange juice.
This adds up to a total of 30 bottles.
Now we want to find the probability of pulling a bottle of apple juice after you pulled one bottle of apple juice.
The probability of pulling a bottle of apple juice at the beginning is equal to the quotient between the number of apple juice bottles in the cooler and the total number of bottles in the cooler,
This means that 12 out of 30 are apple juice, then the probability of getting first a bottle of apple juice is:
p = 12/30
Now, we want to find the probability of getting another, we will do the same calculation than above, but now the number of bottles of apple juice is 11 (because we took one) and the total number of bottles is 29.
In this case, the probability is:
q = 11/29
The joint probability (the probability of both events happening) is equal to the product of the individual probabilities.
Then the probability of pulling apple juice and then pulling another apple juice is:
P = p*q = (12/30)*(11/29) = 0.232

What is 56/2?
Answer:
28
Step-by-step explanation:
Answer:
56 divided by 2 would be 28.
Step-by-step explanation:
[tex]\frac{56}{2}[/tex] is the same thing as half of 56, since two 28s added together is 56, which means [tex]\frac{56}{2}[/tex] is equivalent to 28.
Workout the probability that spinner A lands on 2 and spinner b does not land on b
Spinner diagram isn't attached. A related spinner diagram has been attached below to provide an hypothetical solution to the problem
Answer:
4 / 15
Step-by-step explanation:
For the numbered spinner :
P(landing on 2) = required outcome / Total possible outcomes
Total possible outcomes = (1, 2, 3) = 3
Required outcome = (1) = 1
P(landing on 2) = 1 /3
Lettered spinner :
P(does not land on b)
Total possible outcomes = (A, B, C, D, E)
Required outcome = (a, c, d, e)
P(does not land on b) = 4 / 5
Hence,
P(lands on 2, does not land on b) in this scenario is :
1/3 * 4/5 = 4 / 15

Aiden researches and finds that 37% of students at his school participate in the after school program. Aiden takes a random sample of 50 students and finds that 27 students participate in the after. Which statement correctly describe the sample ratio?
O The sample ratio is 27%, which is above the population ratio.
O The sample ratio is 27%, which is below the population ratio.
O The sample ratio is 54%, which is above the population ratio.
O The sample ratio is 54%, which is below the population ratio.
Answer:
Divide the number of students who participate in the after school program by the number of students in the sample. Multiply by 100 to find the percentage.
Step-by-step explanation:
Use the random sample to make an inference about the sample and population.

Cameron has a balance of $10,200 on his credit card. He threw the card away so he can never use it again. He has 3.5 years to pay off the balance. The interest rate on his card is 21%.
At the end of the 3.5 years, how much money in interest alone will Cameron have paid?
When Cameron finally pays off his credit card, how much will he have paid in all?
Answer:
the interest is $9,676.91 and the future value amount is $19,876.91
Step-by-step explanation:
The computation is shown below;
The future value is
= Present value × (1 + rate of interest)^number of years
= $10,200 × (1 + 0.21)^3.5
= $19,876.91
Now the interest amount is
= Future value - present value
= $19,876.91 - $10,200
= $9,676.91
Hence, the interest is $9,676.91 and the future value amount is $19,876.91

?
Meters to centimeters
Answer:
It grows 221 centimeters in 13 weeks.
Step-by-step explanation:
Each meter has 100 centimeters.
A coral reef grows 0.17 m every week
So it grows 0.17*100 = 17 cm every week.
How much does it grow in 13 weeks?
17 cm every week for 13 weeks, so
17*13 = 221
It grows 221 centimeters in 13 weeks.

find the given polynomial by finding the greatest common monomial factor or the ñegative of the greatest common monomial factor and rewrite the expression.
Answer:
1. The greatest common monomial factor is xy
2. xy(6 + 2y² + 3x²)
Step-by-step explanation:
6xy + 2xy³+ 3x³y
1. Determination of the greatest common monomial (GCM) factor.
6xy + 2xy³+ 3x³y
6xy => 2 × 3 × x × y
2xy³ = 2 × x × y × y × y
3x³y = 3 × x × x × x × y
GCM => xy
2. Rewrite the expression
6xy + 2xy³+ 3x³y
GCM => xy
6xy + 2xy³+ 3x³y = xy(6 + 2y² + 3x²)
The area of a square is 1800 in2, how long is each diagonal?
9514 1404 393
Answer:
60 in
Step-by-step explanation:
The area of a square can be computed as ...
A = (1/2)d^2 . . . . where d is the length of the diagonal
For an area of 1800 in^2, the diagonal length can be found as ...
1800 in^2 = 1/2d^2
3600 in^2 = d^2
d = √3600 in = 60 in
The length of each diagonal is 60 inches.

Step-by-step explanation:
Make sure both fractions of the denominators are the same.
1 x 4 = 4
9 x 4 = 36
3 x 9 = 27
4 x 9 = 36

solve the system using substitution x=-4y y=2x+9
Answer: x=-4
Step-by-step explanation:
Given
x=-4y
y=2x+9
Rephrase equation to find y value in terms of x
y=-x/4
y=2x+9
Use substitution (substitute value of y)
2x+9=-x/4
Multiply -4 on both sides
-4(2x+9)=-4(-x/4)
-8x-36=x
Add 8x on both sides
-8x-36+8x=x+8x
-36=9x
Divide 9 on both sides
-36/9=9x/9
x=-4
