62% of what is 89.3?
To find 62% of what number equals 89.3, divide 89.3 by the decimal form of 62%, which is 0.62, to get 144.03 (rounded to two decimal places).
Explanation:The student's question '62% of what is 89.3?' is asking for the calculation of a base amount from a known percentage and a known result of that percentage. To find the answer, we divide the known result by the percentage in decimal form.
The equation we use is: Base = Percentage Result ÷ Decimal Percentage
Firstly, we convert 62% into decimal by dividing by 100, which equals 0.62. Then we divide the known result, 89.3, by 0.62:
Base = 89.3 ÷ 0.62 = 144.03225806451613
So, 62% of 144.03 (rounded to two decimal places) is 89.3.
Final answer:
The student's question involves finding the original whole given a part and its percentage. The calculation shows that 62% of 144.03 is 89.3.
Explanation:
The student is asking how to find the original whole when given a percentage and the corresponding part of that whole. To find the whole when you know a percentage of it and the actual amount that percentage represents, you can use the formula:
Whole = Part / (Percentage / 100). In this case, the part is 89.3 and the percentage is 62%. So, you calculate the whole by dividing 89.3 by 0.62 (which is 62% converted to a decimal by dividing by 100).
Here’s the step-by-step calculation:
Convert the percentage to a decimal: 62% = 0.62.Divide the part by the decimal: 89.3 / 0.62 = 144.03.Therefore, 62% of 144.03 is equal to 89.3.

suppose that f(x) = 4x+7 and g(x) =2x. what is a rule for g(f(x)? what is a rule for f(g(x))? suppose that f(x) = 4x+7 and g(x) =2x. what is a rule for g(f(x)? what is a rule for f(g(x))?
The rule for g(f(x)) is 8x + 14, and the rule for f(g(x)) is 8x + 7.
Explanation:The rule for g(f(x)) is that we first substitute f(x) into g(x), meaning we replace x in the g(x) rule with the expression for f(x). Using the given functions, g(f(x)) = g(4x + 7) = 2(4x + 7) = 8x + 14.
Similarly, the rule for f(g(x)) is that we first substitute g(x) into f(x), meaning we replace x in the f(x) rule with the expression for g(x). Using the given functions, f(g(x)) = f(2x) = 4(2x) + 7 = 8x + 7.

What is the common difference d of the sequence? −15, −4, 7, 18, 29, ...
Answer:
The common difference is [tex]11[/tex]
Step-by-step explanation:
we know that
In an Arithmetic Sequence the difference between consecutive terms is a constant called the common difference
so
In this problem we have
[tex]-15,-4,7,18,29,...[/tex]
Let
[tex]a1=-15\ a2=-4\ a3=7\ a4=18\ a5=29[/tex]
Find the difference between consecutive terms
[tex]a5-a4=29-18=11[/tex]
[tex]a4-a3=18-7=11[/tex]
[tex]a3-a2=7-(-4)=11[/tex]
[tex]a2-a1=-4-(-15)=11[/tex]
therefore
The sequence is an Arithmetic Sequence
The common difference is [tex]11[/tex]

Mary is putting money into a checking account. Let y represent the total amount of money in the account (in dollars). Let x represent the number of weeks Mary has been adding money. Suppose that x and y are related by the equation =+75030xy . Answer the questions below. Note that a change can be an increase or a decrease. For an increase, use a positive number. For a decrease, use a negative number.
What is the change per week in the amount of the account?
what was the starting amount money in the account?
The starting amount would be the 750, because it doesn't have a variable assigned to it.
And, Change per week is 30 since it is being multiplied by the number of weeks.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Let y represent the total amount of money in the account (in dollars).
And, Let x represent the number of weeks Mary has been adding money.
Here, Suppose that x and y are related by the equation;
⇒ y = 750 + 30x
Now, Clearly for the starting amount money in the account we can put x = 0 in above equation;
⇒ y = 750 + 30 × 0
⇒ y = $750
And, The change per week in the amount of the account is 30 which is being multiplied by the number of weeks.

Answer: A toad population is increasing by about 7.5% each year.
An event organizer finds each year's attendance for the past five years is about 4/5 of the previous year's attendance.
Step-by-step explanation:
On the highway, Kareem's car gets 38 mpg.
This can be modeled with a linear relationship between the miles and the gallons of fuel needed.
Shu Fang has $25.75 deducted from her checking account every month.
Here we know that each month a constant amount is deducted from her, this is not an exponential relation.
A toad population is increasing by about 7.5% each year.
If the population initially was an amount P, after one year the population is P*1.075, after two years the population is P*(1.075)^2 and so on, this can be modeled with an exponential function where the years variable, the function will have the general form:
Population(y) = P*(1.075)^y
An event organizer finds each year's attendance for the past five years is about 4/5 of the previous year's attendance.
If the first year the population is X, the year after the attendance will be (4/5)X, and the year after this process applies again, so you have a 4/5 of the previous attendance, the attendance now is (4/5)^2*X
This also can be modeled with an exponential function, of the shape:
Attendance (y) = X*(4/5)^y, where again, y means years.
The thing you may notice is that in this case the model only works for the lapse of 5 years that the event organizer said.
