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.Geometry HELP! Please help if your good with geometry. Thanks
Answer:
20a. 143 deg
20b. 37 deg
20c. corresponding angles, congruent
20 d. same-side interior angles, supplementary
Step-by-step explanation:
20a.
m<7 = 34
m<5 + m<7 = 180 (linear pair)
m<5 = 180 - 37 = 143
m<4 = m<5 = 143 (alt int angles)
20b.
m<2 = m<7 = 37 (alt ext angles)
20c. corresponding angles, congruent
20d. same-side interior angles, supplementary
(a)
∠7 = 37° = ∠6 ( vertical angles )
∠4 = 180° - 37° = 143° ( 4 and 6 are supplementary interior angles )
(b)
∠2 = 37° (2 and 4 form a straight angle )
(c)
∠4 and ∠8 are corresponding congruent angles
(d)
∠3 and ∠5 are supplementary interior angles
An adventure game has a number cube with 12 equal-size faces. Each face is labeled with a number from 1 to 12. What is the probability of rolling a 4 or a multiple of 5? Enter your answer as a fraction, in simplified form, in the box. $\text{Basic}$ $x$$y$$x^2$$\sqrt{ }$$\frac{x}{ }$$x\frac{ }{ }$$x^{ }$$x_{ }$$\degree$$\left(\right)$$\abs{ }$$\pi$$\infty$
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.
the difference between −5y+1 and 3y+2 is equal to −9. find y
Answer:
Step-by-step explanation:
(−5y+1) - (3y+2) = −9
(-5y-3y) + (1-2) = -9
-8y - 1 = -9
-8y = -8
y = 1
the difference between the 2 expressions is
- 5y + 1 - (3y + 2 ) = - 9
- 5y + 1 - 3y - 2 = - 9
- 8y - 1 = - 9 ( add 1 to both sides )
- 8y = - 8 ( divide both sides by - 8 )
y = 1
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.

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]

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].
y=x vertical compression compression by a factor of 1/7 please compress the equation of y=x by a vertical compression of 1/7
Answer: y = 1/7(x) or y = x/7
Step-by-step explanation:
Hey there! Thank you for submitting your question to Brainly!
In order to vertically compress the equation y = x by 1/7, we would simply need to multiply x by 1/7. Therefore, this gives us the equation y=1/7(x) or y=x/7.
Hope this helps!! :)
A vertical compression by a factor of 1/7 to the equation y=x results in the new equation y=1/7x where each y-value of the original function is 1/7 of its original height.
Explanation:A vertical compression by a factor of 1/7 to the equation y=x results in the new equation y=1/7x. In vertical compression, each y-value of the original function is multiplied by the factor of compression, in this case, 1/7. Thus y=x becomes y=1/7x. This means for any x value in the original function, the corresponding y value in the new function is 1/7 of its original height. For example, where x was 1, y was also 1 for the original equation. In the new equation, when x is 1, y is now 1/7.

calculating each of the products
noting that i² = (√- 1 )² = - 1
(1 + 2i)(8i) ( distribute by 8i )
= 8i + 16i² = - 16 + 8i ← complex number
(1 + 2i)(2 - 5i) ( expand using FOIL )
= 2 - 5i + 4i - 10i²
= 2 - i + 10 = 12 - i ← complex number
(1 + 2i)(1 - 2i) ( expand using FOIL )
= 1 - 2i + 2i - 4i²
= 1 + 4 = 5 ← real number
(1 + 2i)(4i) ( distribute by 4i )

A rectangular park has an area of 250 square feet. The length of the park is 7 feet more then twice the width, w of the park. Which equations, in terms of w, model this situation
Area = length * width
width = w
length = 2w+7
A = (2w+7) * w
250 =2w^2+7w
0 = 2w^2 +7w-250
w is the width, hence length is 2w + 7 ( 7 more than twice the width )
area = length × width = w( 2w + 7 ) = 250
2w² + 7w - 250 = 0 ← in standard form

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
