A 9-inch candle burns down in 12 hours. After how many hours will it have burned
3 3/8 inches?
Answers
Answer:
4.5
Step-by-step explanation:
Use a proportion.
3 3/8 = 3.375
9 inch is to 12 hours as 3.75 inches is to x hours.
9/12 = 3.375/x
3/4 = 3.375/x
3x = 4 * 3.375
x = 4 * 1.125
x = 4.5
Answer: 4.5 hours
Using rate if a 9-inch candle burns down in 12 hours, the amount of hours it have burned 3 ³/₈ inches is 4 ¹/₂ h
What is a rate?Rate is the amount per unit time of a substance
Since a 9-inch candle burns down in 12 hours. To determine after how many hours will it have burned 3 ³/₈ inches, we proceed as follows.
.
First, we calculate the rate at which it burns which is given as r = Length of candle/time
Since
Length of candle = 9 in andtime = 12 hoursSubstituting the values of the variables into the equation, we have that
r = Length of candle/time
r = 9 in/12 h
r = 3/4 in/h
To determine how many hours it would have burned 3 ³/₈ in, we have that
rate, r = Length/time
time = Length/rate
Since
Length = 3 ³/₈ in = 27/8 in andrate = 3/4 in/hSubstituting the values of the variables into the equation, we have that
time = Length/rate
= 27 in/8 ÷ 3/4 in/h
= 27/8 in × 4/3 h/in
= 9/2 h
= 4 ¹/₂ h
So, it will have burned for 4 ¹/₂ h

A flat fee of $15.25 plus $3.45 per pound of supplies ordered is added to the bill to cover the shipping cost.The teacher budgets $49.75 for the shipping cost.Which list of values best represents the entire domain for shipping, f(x), as a function of the number of whole pounds of school supplies the teacher can order, x?
Answers
The domain of a function is the set of possible input value, the function can take.
The domain is [0,10]
The given parameters are:
[tex]Flat\ Fee = 15.25[/tex]
[tex]Rate = 3.45[/tex]
So, the function f(x) is:
[tex]f(x) = Flat\ Fee + Rate \times x[/tex]
[tex]f(x) = 15.25 + 3.45 \times x[/tex]
[tex]f(x) = 15.25 + 3.45x[/tex]
Because x represents the number of orders, the value of x cannot be negative.
The teacher budgets $49.75.
This means that: f(x) = 49.75
So, we have:
[tex]49.75 = 15.25 + 3.45x[/tex]
Collect like terms
[tex]49.75 - 15.25 = 3.45x[/tex]
[tex]34.5 = 3.45x[/tex]
Divide both sides by 3.45
[tex]10 = x[/tex]
Rewrite as
[tex]x = 10[/tex]
Hence, the domain is [0,10]

The length of a rectangle is 3 inches more than its width. if the perimeter is 42 inches, find the dimensions of the rectangle
Answers
Answer:
length = 12
width = 9
Step-by-step explanation:
Let w= width of rectangle
length = w + 3
2w + 2(w + 3) = 42
2w + 2w + 6 = 42
4w = 36
w = 9 ( width of rectangle)
width = 9 inches
length = 9 + 3 = 12 inches

Answer:
(x +6)(3x +4)
Step-by-step explanation:
The usual approach to this is to look for factors of the product 3·24 that have a sum of 22.
72 = 1·72 = 2·36 = 3·24 = 4·18 = 6·12 = 8·9
Sums of these factor pairs are 73, 38, 27, 22, 18, 17.
Now, you can rewrite the expression splitting the middle term into two parts:
3x² +4x +18x +24
x(3x +4) +6(3x +4) . . . . . . factor by grouping
(x +6)(3x +4) . . . . . . . . . . your factored form
_____
Additional comment
I find this method easiest to explain and to do without error. There are various "X" methods in which you write the product at the top (3·24) and the sum at the bottom (22), then fill in the sides with the factors having that product and sum (4, 18). When the leading coefficient is not 1, there are methods added to this that get you to the correct factors.
One such method is to use the leading coefficient inside parentheses: (3x+4)(3x+18) Then divide that product by the leading coefficient:
(3x +4)(3x +18)/3 = (3x +4)(x +6).
In some cases, each of the binomials needs to be divided by part of the leading coefficient; not the whole thing, as here.

Tina babysits children in her neighborhood. When Tina is asked her rate, she tells her neighbors that she charges $15 for the first hour and $8 for each hour after. If Tina's neighbor asks Tina to babysits for 4 hours, how much will Tina earn? Write an equation to model and solve the problem. Write the answer as an ordered pair and explain the meaning of the ordered pair.
Answers
The amount charged is an illustration of a linear equation.
Tina charges $39 for 4 hours
The given parameters are:
[tex]Base = 15[/tex] --- amount charged for the first hour
[tex]Rate = 8[/tex] --- amount charged for the extra hours
If Tina babysits for 4 hours, it means that:
She will charge $15 for the first hour$8 for the extra 3 hoursSo, the total charges is:
[tex]Total = 15 + 3 \times 8[/tex]
[tex]Total = 15 + 24[/tex]
[tex]Total = 39[/tex]
The ordered pair is (4,39)
