A rectangular wall measures 15 ft along the floor. The area of
the wall is 180 ft². What is the height of the wall?
Answer:
The height is 12ft
Step-by-step explanation:
In order to find the height, you have to divide the area by the width which is 180ft divided by 15ft, you get 12ft, and if you double-check 15 x 12 gets you 180, which is the area.

A frozen yogurt stand charges per ounce of frozen yogurt purchased. There is an extra charge for a waffle bowl. The total cost (c), in dollars, for f ounces of frozen yogurt in a waffle bowl, is described by the function c = 0.45f + 1.
Which statement is true?
A. The cost of 0.45 ounce of frozen yogurt in a waffle bowl is $1.
B. Each ounce of frozen yogurt costs $1 and a waffle bowl is $0.45 extra.
C. Each ounce of frozen yogurt costs $0.45 and a waffle bowl is $1 extra.
D. The cost of 0.45 ounce of frozen yogurt in a waffle bowl is $1.45.
The true statement when the frozen yogurt stand charges per ounce of frozen yogurt purchased is B. Each ounce of frozen yogurt costs $1 and a waffle bowl is $0.45 extra.
How to explain the function?In the scenario, the total cost (c), in dollars, for f ounces of frozen yogurt in a waffle bowl, is described by the function c = 0.45f + 1.
In this case, it is important to note that Each ounce of frozen yogurt costs $1 and a waffle bowl is $0.45 extra.
For example, for 2 ounces, this will be:
= 0.45f + 1
= 0.45(2) + 1
= 0.9 + 1

Find the amount of money you will have after 20 years if you invest $25,000 at a rate of 12% if interest is compounded a. Quarterly b. Continuously
The compound interest is quaterly then answer is $266,022.2639 and when it is in continuously then answer is $275,579.4095
Quarterly compounding is what?
Compounding quarterly is the term used to describe the amount of interest that is earned on a quarterly basis on a savings account or investment where the interest is also reinvested. As most banks offer interest income on the deposits, which compounds quarterly, this information is useful in computing the fixed deposit income. It can also be used to figure out any revenue from money market instruments or other financial products that pay quarterly income.
What Does Constant Compounding Mean?
If compound interest is calculated and reinvested into the balance of an account across an essentially unlimited number of periods, continuous compounding is the mathematical limit that compound interest can reach. While this is not attainable in practice, the concept of continually compounded interest is crucial in finance. Given that most interest is compounded on a monthly, quarterly, or semiannual basis, this is an extreme example of compounding.
a) A = P(1 + r/n)nt
P = $25000
r = 12% = 0.12

Johnny is 5 years younger than twice Bobby's age. If the sum of thier ages is over 66 years.
What is the Johnny's minimum age?
The minimum age of Johnny is 21 as calculated by linear inequality.
Let Johnny 's age be x.
hence bobby's age = (x+5)/2
Now the sum of their ages is over 66 years.
So we will set an inequality to find the minimum age of Johnny.
x + (x+5)/2 > 66
or, 2x + x + 5 > 66
or, 3x > 61
or, x > 20 1/3
Therefore age cannot be fraction hence the minimum age of Johnny is 21 years.
In mathematics, an inequality is a connection that makes an unequal comparison between two numbers and maybe other mathematical expressions. On that number line, size comparisons between two numbers are typically done. Different notations can be used to represent various kinds of inequalities, including:
A is smaller than b, as shown by the symbol a < b.
When the expression a > b is employed, it means that a is greater than b.

A family has two cars. During one particular week, the first car consumed 30 gallons of gas and the second consumed 40 gallons of gas. The two cars drove a combined total of 1600 miles, and the sum of their fuel efficiencies was 45 miles per gallon. What were the fuel efficiencies of each of the cars that week?
If the fuel efficiencies of each of the cars that week is 20 gallons of gas and 25 gallons of gas.
How to find the efficiencies?Let x represent the gallons consumed by car 1
Let y represent gallons consumed by car 2
Formulate an equation:
30x+40y = 1600 equation 1
x+y = 45 equation 2
Substituting equation 2 into equation 1,
30x+40(45-x) = 1600
30x+ 1800-40x = 1600
-10x+1800 = 1600
-10x = -200
Divide both side by -10x
x = -200/-10
x = 20
Substitute value of x into equation 2
x+y = 45
20+y = 45
y = 25
Hence,
Car 1 consumes 20 gallons of gas and Car 2 consumes 25 gallons of gas.

An online electronic store's sales are currently increasing at a rate of 2.7% monthly. If they had $65,000 in sales for this month, what will their sales be in 1 year?
The Sales of the electronic store in 1 year is 66,776.88
Applications of Compound interest:
Compound interest is an interest that is calculated on the principal and the interest accumulated over the previous period. The concept of compound interest can be used in different types of situations like an Increase in population or a decrease in population, Depreciation, or increasing the value of an item, etc.
The formula for compound interest is given by
Total amount, A = P(1 + r/n)^nt
where P = initial amount
r = rate of increase
n = number of compounds in year
t = time period in years
Here we have,
The rate of increase in sales r = 2.7% (per monthly)
=> r = 2.7/100 = 0.027
Here sales are increased monthly
then the number of compounds per year = 12
Sales in this month, P = 65000
From above formula
Sales in 1 year, A = 65000(1 + 0.027/12)¹²
= 65,000(1 + 0.00225)¹²
= 66,776.88
Therefore,
Sales of the electronic store in 1 year = 66,776.88

The image of point (2,0) after the transformation involving the dilation and the rotation is given as follows:

What are the transformations applied to the point?The first transformation applied to the point is a dilation, which multiplies the coordinates of the point by the scale factor.
The point has these following coordinates:
(2,0).
The scale factor of the dilation is:
k = 1/2 = 0.5.
Then each coordinate of the point is multiplied by 0.5, hence:
2 x 0.5 = 1.0 x 0.5 = 0.Hence the coordinates are:
(1,0).
The rule for a rotation of 270º clockwise around the origin is:
