Let the width of rectangle be X inches
Then according to question
Length of rectangle will be 3X
Also, we know that
Area of rectangle is = L×B
108 = X . 3X
3X^2 = 108
Divide both sides by 3
X^2 = 36
Taking squareroot of both sides
X=6
Therefore, width of rectangle is 6 inches
Answer:
1. 6 in.
Step by step explanation:
Let the width of our rectangle be x inches.
We have been given that the length of our rectangle is three times the width, therefore, length of our triangle will be 3x inches.
We are told that area of the rectangle is 108 square inches.
Since we know that [tex]\text{Area of a rectangle}=\text{Width}\cdot\text{Length}[/tex]
Let us substitute our given information in area formula.
[tex]108=x\cdot 3x[/tex]
Upon multiplying 3x by x we will get,
[tex]108=3x^{2}[/tex]
Let us divide both side of our equation by 3.
[tex]\frac{108}{3} =\frac{3x^{2}} {3}[/tex]
[tex]36=x^{2}[/tex]
Upon taking square root of both sides of our equation we will get,
[tex]6\pm=x[/tex]
Since width cannot be negative, therefore, width of our rectangle will be 6 inches and 1st option is the correct choice.
an inch is 1/12 of a foot how much has a angelfish grown in a feet
To find out how much an angelfish has grown in feet, divide the number of inches by 12, since there are 12 inches in a foot. As an example, if an angelfish has grown 6 inches, it would be 6 inches / 12, equaling 0.5 feet.
Explanation:To convert a measurement from inches to feet, we use the fact that one foot is equal to 12 inches. For example, if an angelfish has grown 6 inches, we divide the number of inches by 12 to find the growth in feet:
Find the growth in inches (for example, 6 inches).Use the conversion factor, which is 1 foot = 12 inches.Divide the growth in inches by 12 to get the growth in feet. For 6 inches: 6 inches / 12 inches per foot = 0.5 feet.The angelfish has grown 0.5 feet.
Similarly, let’s convert 374 inches to feet as another example of going from a smaller unit to a larger unit:
Take the given number of inches and divide by 12 since there are 12 inches in a foot.374 inches divided by 12 equals 31(1/6) feet.Mr. Tragrr has $500.00 to spend at a bicycle store. All the prices listed down below include tax.
• He buys a new bicycle for $273.98
• He buys 3 new bicycles for $7.23 each and 1 bicycle helmet for $42.36
• He plans to use the remaining money to buy new cycling outyfor $78.12each.
What is the GREATEST number of cycling outfits thatMr. Traeger can buy withthe remaining money?
To answer the question, you need to determine the amount Mr. Traeger has left to spend, then find the maximum number of outfits that will cost less than that remaining amount.
Spent so far:
... 273.98 + 3×7.23 +42.36 = 338.03
Remaining available funds:
... 500.00 -338.03 = 161.97
The cycling outfits are about $80 (slightly less), and this amount is about $160 (slightly more), which is 2 × $80.
Mr. Traeger can buy two (2) cycling outfits with the remaining money.
_____
The remaining money is 161.97/78.12 = 2.0733 times the cost of a cycling outfit. We're sure he has no interest in purchasing a fraction of an outfit, so he can afford to buy 2 outfits.

Simplify the expression. 12x^-6 y^10 times 3x^7 y
We need to simplify the expression:
[tex]12x^{-6}y^{10} \times (3x^{7}y)[/tex]
Now, we know that we can resolve the exponents of the variables with the like terms only and we can multiply the coefficients independently:
Now,
[tex]12x^{-6}y^{10} \times 3x^{7}y=(12 \times 3)\times (x^{-6}\times x^{7})\times (y^{10}\times y)[/tex]
On simplifying the above expression we get:
[tex]36\times x^{(-6+7)}\times y^{(10+1)}[/tex]
[tex]=36 \times x^{1}\times y^{11}[/tex]
[tex]=36 \times x \times y^{11}[/tex]
[tex]=36xy^{11}[/tex]
So the simplified form of the expression [tex]12x^{-6}y^{10} \times 3x^{7}y=36xy^{11}[/tex].
The surface area, A, of a sphere in terms of its radius, r, is given by A(r) = 4πr2. Express r as a function of A.
r =√ ( A / 4π )
given A = 4πr² ( isolate r² by dividing both sides by 4π )
A / 4π = r² ( take the square root of both sides )
r =√( A / 4π )
Answer:
The expression of r in terms of A is:
[tex]r=\sqrt{\dfrac{A}{4\pi}}[/tex]
Step-by-step explanation:
We are given the surface area, A, of a sphere in terms of its radius, r, as:
A(r) = 4πr²
[tex]A=4\pi\ r^2[/tex]
⇒ [tex]r^2=\dfrac{A}{4\pi}[/tex]
⇒ [tex]r=\sqrt{\dfrac{A}{4\pi}}[/tex]
Hence, the expression of r in terms of A is:
[tex]r=\sqrt{\dfrac{A}{4\pi}}[/tex]

the probability is a ratio of number of relevant outcomes and total number of possible cases.
In this scenario, the relevant outcomes are
4, 5, 10 (and their count is 3)
and the total number of possible outcomes:
12
so the probability is
3/12 = 1/4
the answer is 3/12 cause when you divied 12 by 4 you will get 3 and we know that there is 12 faces on the cube so that gives you the ratio 3/12.

Christine, Henry, and Manuel have a total of $109 in their wallets. Manuel has 3 times what Christine has. Christine has $9 less than Henry. How much do they have in their wallets?
Christine has $20, Manuel has $60 and Henry has $29
let x be the amount Christine has then
Manuel has 3x and Henry x + 9
summing the amounts gives the equation
x + 3x + x + 9 = 109
5x + 9 = 109 ( subtract 9 from both sides )
5x = 100 ( divide both sides by 5 )
x = 20
thus Christine has $29, Manuel has (3 × 20 ) =$60 and
Henry has 20 + 9 = $29
check : 20 + 60 + 29 = 109
