C. 35 feet
D. 32 feet
Alright, so the scale of meters to feet is about 3.281 feet. So you would do 10.7 times 3.281 and that equals 35.1067 and that can be rounded to 35, so the answer would be C, 35 feet. Hope that Helped :)!
A trampoline has a rectangular jumping surface that is 10.3 feet long and 9.2 feet wide. What is the area of the jumping surface?
Sure, to find the area of a rectangle, we simply multiply its length by its width. Here, the length of the trampoline's jumping surface is given as 10.3 feet, and the width is given as 9.2 feet.
Step 1: Write down the length and width.
Length = 10.3 feet
Width = 9.2 feet
Step 2: Multiply the length by the width.
Area = Length × Width = 10.3 feet × 9.2 feet
Perform this multiplication to get the area.
Result: The area of the jumping surface of the trampoline is 94.76 square feet.
This means that the total surface area upon which someone can jump on the trampoline is 94.76 square feet.

Rafael is taking a test that contains a section of 12 true-false questions. How many of the possible groups of answers to these questions have exactly 8 correct answers of false? a. 425 c. 500 b. 495 d. 515
Answer: 495
==============================================================
We want exactly 8 correct answers of false, so we want exactly 4 correct answers of true. In short, we want something like FFFF FFFF TTTT. Because the sequence of T values is shorter than the F values, this means it's a lot easier to count out the number of ways to pick the true responses, rather than the false responses.
Consider we have 4 slots: A, B, C, D
In slot A, we can pick the number 1 through 12 to represent getting a T
For slot B, we have 11 choices because we can't reuse whatever we picked for slot A
Then for slot C we have 10 choices
Finally, slot D has 9 choices
Multiply those values out: 12*11*10*9 = 11,880
If order mattered, then we'd be done with the problem. However, order does not matter. This is because a sequence like {1, 2, 3, 4} is the same as {1,2,4,3}. The only thing that matters is that we have the numbers in the same group. We can rearrange any given group however we want.
Note that there are 4! = 4*3*2*1 = 24 ways to arrange any individual group of four items. So we have to divide the previous result 11,880 by 24 and we get: 11880/24 = 495 which is the answer
If you wanted, you can use the nCr combination formula to get this same answer. You would use n = 12 and r = 4
f(x) = 3x2 - 2x g(x) = x + 4 When finding f(x) · g(x), what could the first step look like? A) 3x2 + 12x2 - 2x2 - 8x B) 3x2 + 7x2 - 2x2 + 2x C) 3x3 + 12x2 - 2x2 - 2x D) 3x3 + 12x2 - 2x2 - 8x
(3x^2 - 2x)(x + 4)
First step would be: distributive property.
3x^3 + 12x^2 - 2x^2 - 8x
Combine like terms.
3x^3 + 10x^2 - 8x is the simplified form of the functions multiplied.
Your answer is D.
Final answer:
The first step in finding f(x) · g(x) involves multiplying the two functions together, following the distributive property, resulting in terms like 3x³ and 12x².
Explanation:
When finding f(x) · g(x), the first step would involve multiplying the two functions together. This means multiplying each term of f(x) by each term of g(x) using the distributive property.
For f(x) = 3x² - 2x and g(x) = x + 4, the first step would look like:
f(x) · g(x) = (3x² - 2x) · (x + 4) = 3x² · x + 3x² · 4 - 2x · x - 2x · 4 = 3x³ + 12x² - 2x² - 8x
So, the correct option in this case is A) 3x³ + 12x² - 2x² - 8x.

Solve the formula for the indicate variable A=zv+x, for v
the volume of a cube is 64 cubic inches. what is the length of one side?
To solve for the volume of the cube, you must use the formula:
Volume = a³
"a" being an edge.
Plug in 64 for Volume
64 = a³
Note the equal sign. What you do to one side, you do to the other. Cube root both sides
∛64 = ∛a³
a = ∛64 = 4
4 inches is your answer
hope this helps
To find the length of one side of a cube with a volume of 64 cubic inches, take the cube root of the volume, which results in a side length of 4 inches.
The volume of a cube is found by cubing the length of one of its sides since a cube's sides are all equal in length. For a cube with a volume of 64 cubic inches, you can find the length of one side by taking the cube root of 64.
Steps to determine the length of one side of the cube:
Understand that the volume of a cube (V) is equal to the side length (s) cubed: V = s³.Since the volume is 64 cubic inches, set up the equation 64 = s³.Take the cube root of both sides of the equation to find s:seven increased by the product of two numbers
Seven increased by the product of two numbers

What is the measure of each exterior angle for a regular nonagon
The sum of the exterior angles of any polygon is 360 degrees. Therefore to find the measure of one exterior angle of any regular (all angles are congruent) polygon, divide 360 by the number of angles. In the case of a regular nonagon, the measure of one exterior angle is 40 degrees: 360 / 9 = 40 degrees. its my best guess
In a regular nonagon, each exterior angle measures 40 degrees.
A regular nonagon is a polygon that has nine sides of equal length and nine interior angles of equal measure.
To determine the measure of each exterior angle for a regular nonagon, you can follow these steps. Recall that a nonagon is a polygon with nine sides. The sum of the exterior angles of any polygon is always 360 degrees.
Divide the sum of the exterior angles (360 degrees) by the number of sides in the nonagon (9) to find the measure of each exterior angle.
Calculate: 360 degrees ÷ 9 = 40 degrees.
Therefore, each exterior angle in a regular nonagon measures 40 degrees. This means that if you were to extend one side of a regular nonagon outward, the angle formed between that extended side and the adjacent side would measure 40 degrees.

Adrian earns $3600 per month. he spends 1/4 of his income on rent, 2/5 on food, 1/9 on activities, and he saves the rest. how much does he save each month?
he saves $860 per month
calculate each of his outgoings
rent = [tex]\frac{1}{4}[/tex] × $3600 = [tex]\frac{3600}{4}[/tex] = $900
food = [tex]\frac{2}{5}[/tex] × $3600 = [tex]\frac{2(3600)}{5}[/tex] = $1440
activities = [tex]\frac{1}{9}[/tex] × $3600 = [tex]\frac{3600}{9}[/tex] = $400
savings = $3600 - ( 900 + 1440 + 400 ) = $860
To add the fractions we must make the denominators = 180.
45/180 + 72/180 + 20/180 = 137/180
Expense Total = (137/180) * 3,600 = $2,740
Savings Total = (180 - 137) / 180
Savings = (43/180) * 3,600
Savings = $860

Helen wrote the following facts to try to show that division by 0 results in 0. Explain her error.
Helen should of put 0 first, because if you're gonna divide, you need to put the product first, then one of the factoes.
So instead it should be 0÷(-7)=0
Helen's assertion that division by 0 results in 0 is incorrect. Her error lies in a fundamental mathematical principle: division by zero is undefined in arithmetic.
How to determine Helen errorDividing any number by 0 is mathematically impossible and not meaningful. It does not yield a value of 0 or any other number because the concept is not valid in standard arithmetic. When you attempt to divide by 0, you encounter mathematical inconsistency and contradiction.
In mathematics, there are well-defined rules and operations for manipulating numbers, and division by zero does not adhere to these rules. It is considered undefined, and no meaningful result can be assigned to it. Therefore, Helen's statement is not accurate, and division by zero is not equivalent to 0 in mathematics.

Answer:
Hey there! :) y = 3x - 7
Step-by-step explanation:
Our very first step should be to rewrite our question.
3x = y + 7 ; solve for y.
In order to find out what y is equal to, we must isolate y. We can do this bu subtracting 7 from both sides of the equal sign.
3x - 7 = y + 7 - 7
Simplify.
3x - 7 = y
Therefore, y is equal to 3x - 7.
