"Our proportionality constant would be how much the rope stretches versus the weight being hung. This is set up by simply dividing the two numbers.
9.6 inches / 8 pounds
or for every pound hung, it will stretch 1.2 inches so we know if it stretches 6 inches, we can set up an equation 6 inches = 1.2 [inches/pound] * pounds solve for weight to get 5 pounds being hung from the rope."
Answer: 9.6 inches / 8 pounds

If f(x) = 3x + 10x and g(x) = 2x – 4, find (f – g)(x).
Final answer:
To find (f - g)(x), subtract the function g(x) from f(x) by expanding and combining like terms.
Explanation:
To find (f - g)(x), we need to subtract the function g(x) from f(x). The given functions are f(x) = 3x + 10x and g(x) = 2x - 4. Let's subtract g(x) from f(x):
(f - g)(x) = (3x + 10x) - (2x - 4)
Expanding the expression, we get:
(f - g)(x) = 3x + 10x - 2x + 4
Combining like terms, we simplify it to:
(f - g)(x) = 11x + 4
If x = y − 2, simplify the expression x + 6. A. x + 4 B. x − 8 C. y + 4 D. y − 8
When measuring board footage for some exotic woods, a carpenter must use 1.25 inches for thickness rather than 1 inch in her calculations. Write 1.25 in expanded form.
Answer: [tex]1.25=1+0.2+0.005[/tex]
Step-by-step explanation:
Given : When measuring board footage for some exotic woods, a carpenter must use 1.25 inches for thickness rather than 1 inch in her calculations.
To write : 1.25 in expanded form.
When we write a decimal number in expanded form, we are showing the place value of each digit.
Now, 1.25 can be written as :
[tex]1.25=1+0.2+0.005[/tex]
Hence, the expanded form of [tex]1.25=1+0.2+0.005[/tex]
what is 24 2/3 divided by 1 3/4
Answer:
Step-by-step explanation:
First, you should convert the mixed fractions into an improper fraction.
74/3 divided by 7/4
As you should know, any fraction divided by another is that fraction times the reciprocal of the other fraction.
74/3*4/7
There fore leaving 296/21 as the answer.
5 less than three times a number is 10
3x-5 =10
add 5 to both sides
3x=15
divide both sides by 3
x=5
check:
3(5)-5 = 15-5 = 10
Which expression shows the simplified form of (8r^-5) -3 ?
Answer:
[tex]\frac{r^{15}}{512}[/tex]
Step-by-step explanation:
(8r^-5)^ -3
[tex](8r^{-5})^{-3)[/tex]
Apply exponential property
(ab^m) ^n = a^m b^mn
Multiply the outside exponent with the exponents insde
[tex](8r^{-5})^{-3)= 8^{-3}r^{-5*-3}=8^{-3}r^{15}[/tex]
Appy property a^-m = 1/a^m to make the exponent positive
[tex]8^{-3}r^{15}= \frac{r^{15}}{8^3} =\frac{r^{15}}{512}[/tex]
Dave is helping his grandmother make trail mix. His grandmother asks him to add cup of fruit for every cup of nuts.
To satisfy his grandmother’s request, Dave must mix cups of fruit for a single cup of nuts.
To satisfy his grandmother's request, Dave needs to mix [tex]\( \frac{1}{5} \)[/tex] cup of fruit for every [tex]\( \frac{1}{3} \)[/tex] cup of nuts.
To find out how many cups of fruit Dave needs to mix for a single cup of nuts, we need to find a common denominator for [tex]\( \frac{1}{5} \)[/tex] and [tex]\( \frac{1}{3} \)[/tex], which is 15.
[tex]\[ \frac{1}{5} \times \frac{3}{3} = \frac{3}{15} \][/tex]
[tex]\[ \frac{1}{3} \times \frac{5}{5} = \frac{5}{15} \][/tex]
So, Dave needs to mix [tex]\( \frac{3}{15} \)[/tex] cup of fruit for every [tex]\( \frac{5}{15} \)[/tex] cup of nuts.
Therefore, to satisfy his grandmother's request, Dave must mix [tex]\( \frac{3}{15} \)[/tex] cup of fruit for a single cup of nuts.
The complete Question is given below:
dave is helping his grandmother make trail mix his grandmother asks him to add 1/5 cup of fruit for every 1/3 cup of nuts. To satisfy his grandmother's request, drave must mix ___ cups of fruit for a single cup of nuts
Which expression is equivalent to 100 n2 − 1? (10n)2 − (1)2 (10n2)2 − (1)2 (50n)2 − (1)2 (50n2)2 − (1)2
The correct answer is:
(10n)² − (1)²
Explanation:
If we evaluate this expression, we square everything in the first set of parentheses; this means we have 10²n² - 1², or 100n² - 1.
This is the expression we were trying to equal.

Estimate the circumference of the circle to the nearest hundredth. Use 3.14 the diameter is 11
The circumference of a circle with a diameter of 11 using 3.14 for pi is estimated to be 34.54 to the nearest hundredth.
Explanation:To estimate the circumference of a circle to the nearest hundredth, we use the formula C = πd, where C is the circumference and d is the diameter of the circle. Given that the diameter is 11 and we should use 3.14 for π, the calculation is C = 3.14 × 11. Performing the multiplication gives us a result of 34.54, which is the estimated circumference of the circle to the nearest hundredth.

3, 4, and 7
9, 40, and 42
8, 15, and 16
20, 21, and 29
the answer is 20,21,29 because
20 times 20 is 400
21 times 21 is 441
and 29 times 29 is 841
the formula to ge tthe answer is a^2 + b^2 = c^2
20^2 + 21^2= 29^2

find the approximate length of the leg of a right triangle with one leg length 8 and hypotenuse length 19
The approximate length of the leg of a right triangle is 17.
Use the concept of a triangle defined as:
A triangle is a three-sided polygon, which has three vertices and three angles which has a sum of 180 degrees.
And the Pythagoras theorem for a right-angled triangle:
(Hypotenuse)²= (Perpendicular)² + (Base)²
Given that,
One leg = 8 say it is the base of a triangle.
Hypotenuse = 19
Applying the Pythagorean theorem,
(19)²= (Perpendicular)² + (8)²
(Perpendicular)² = 297
Taking square root on both sides,
Perpendicular ≈ 17.2
Hence,
The required length of leg is approximately 17.
