Show two ways that six people can share an 8-segment chewy fruit worm. In each case, how many segments does each person get.

Answers

1. 8 divided by 6
2. 6 people eat six parts and 2 parts are left over

Final answer:

Six people can share an 8-segment chewy fruit worm by each person having 1 segment with 2 segments left over, or by each person having 2 segments with no segments left over.

Explanation:

There are two ways that six people can share an 8-segment chewy fruit worm:

Each person can have 1 segment, and there will be 2 segments left over.

Each person can have 2 segments, and there will be no segments left over.

In the first case, each person will get 1/6 of the worm. In the second case, each person will get 2/6 or 1/3 of the worm.

If you solve it, you get x=0. That means you are adding zero, so you are dealing with the additive identity property.
This is known as an Addition Identity Property.

It's a rule that states that if you add zero to a number, you would get the same same number as the answer.

John is building a rectangular puppy kennel up against his house using 31 feet of fencing. The side against the house does not need a fence and the side parallel to his house needs to be 15 feet long. Write an equation that models the situation and solve for the length of one of the shorter sides that extend out from the house.

Answers

Answer:

Each of the shorter sides extended out from the house is 8 feet long.

Explanation:

So John, needs to make a 3 sided fence. He has 31 feet of fencing to do this with and the single side parallel to the house is 15 feet.

We can write the equation for this problem as:

31=2s+15

Where 31 is the total amount of fencing John has to use, 15 is the one side where the length is given, s is the length of each of the other two sides and because there are two sides we multiply s by 2

Solving this equation gives:

31−15=2s+15−15

16=2s+0

16=2s

162=2s2

8=s

Kareen correctly answered 85% of the questions on his last math test. If he missed 6 problems, how many questions were on the test?

Answers

He got 85% correct, which also means he got 15% wrong (the 6 problems)

This means 6=15%

15 does not go into 100 evenly, but 5 does. And 3 happens to be a common factor for both 6 and 15. If you divide both sides by 3 you get:
2=5%

Now we need to find 100%. If 5% of the test is 2 questions, then 100% must be 40.

It's like solving proportions-

2:5
x:100

5 to 100: multiply by 20

2 to x: also multiply by 20

2 times 20 = 40 = 100%

The table shows revenue R (in millions of dollars) of a company when it spends A (in millions of dollars) in advertising.

a. Write a linear function that relates the revenue to the advertising cost.
b. What is the revenue of the company when it spends $10 million on advertising?

(Table is attached below)

Answers

advertising is x and revenue is y

(0,2)(2,6)
slope = (6 - 2) / (2 - 0) = 4/2 = 2

y = mx + b
slope(m) = 2
(0,2)...x = 0 and y = 2
now we sub and find b, the y int
2 = 2(0) + b
2 = b

so ur equation is : y = 2x + 2

spends 10 mill on advertising.....so x = 10
y = 2x + 2
y = 2(10) + 2
y = 20 + 2
y = 22.....so the revenue (y) of the company is 22 (million)

Find the value of the variables.

Options
A. x = 23, y = 134
B. x = 67, y = 46
C. x = 67, y = 134
D. x = 23, y = 46

Answers

B; since we know that angle NKL is 90° and is cut by a diagonal line that angle NKM is 67° since angles MKL and NKM both form a right angle. With this information we could now say that x is 67°, because angles NKM and LMK are alternate interior angles, stated in the alternate interior angles theorem. One of the properties of a parallelogram is that diagonal bisect each other, making all the bisected diagonal congruent, so we could use this information to find y. In the picture you could see highlighted in red the diagonals I will be focusing on. Since these two diagonals are congruent, but not the base side, this makes the shape of an isosceles triangle. We know that isosceles triangle's base angles are congruent, so we have to make label the base angles both 67°. Because of the Triangle Sum Theorem, the triangle has to equal 180°, so we add the base angles to get 134°, then we have to subtract 180° and 134° to get 46°, which is your y.

Answers

Answer:

The answer is C 2800 ft2.

Step-by-step explanation:

I just took a quiz and that was the answer. I honestly don't know why.

Final answer:

To find the area to be painted on the cylinder-shaped water tower, we sum the areas of the top and sides. The water tower has a height of 60 feet and a radius of 20 feet, resulting in a total area of 2800π ft^2 to paint.

Explanation:

The City of Oz needs to repaint its cylinder-shaped water tower. To calculate the total surface area to be painted, which consists of the top (a circle) and the sides (a rectangle wrapped around), we use the formulas for the area of a circle and the lateral surface area of a cylinder:

Area of the top (circle) = πr²

Lateral surface area (sides) = 2πrh

The water tower has a height of 60 feet and a radius of 20 feet.

Area to paint = Area of the top + Lateral surface area = π(20 ft)² + 2π(20 ft)(60 ft) = 400π ft² + 2400π ft² = 2800π ft².

Therefore, the correct answer is C) 2800π ft².

what's does y equal to x=3-3y

Answers

Solve for y by simplifying both sides of the equation, then isolating the variable.
y = 1 - x/3
Beginning with x=3-3y and solving for y, the first step would be to move the constant 3 to the opposite side of the equation by subtracting it from both sides, which leaves x-3 = -3y.

Now divide both sides by the coefficient of y, which is -3 to get (x-3)/-3 = y

This could be rewritten as -(1/3)*(x-3) = y or -x/3 + 1 = y

To solve for y in the equation 3x + 1/5y = 7, subtract 3x from both sides, then multiply by 5, resulting in y = 35 - 15x.

To solve the equation [tex]3x + \frac{1}{5}y = 7[/tex] for y, we need to isolate y on one side of the equation.

Subtract 3x from both sides of the equation to get the term with y by itself:

[tex]\frac{1}{5}[/tex]y = 7 - 3x

Multiply both sides of the equation by 5 to solve for y:

y = 5(7 - 3x)

Simplify the right-hand side:

y = 35 - 15x

This equation now represents y in terms of x.

To find the powers of 3 that lie within the range from 3 to 1000, start with 3 to the power of 1 and continue to increment the exponent until the resulting power of 3 is greater than 1000. The sequence of powers of 3 in this range is 3, 9, 27, 81, 243, and 729.

The student is asking about finding the powers of 3 that are within the range from 3 to 1000. This is a mathematics question that involves exponents and integer powers. To find the powers of 3 within this range, we'd start with 31 (which is 3), and increment the exponent by 1 until the result exceeds 1000.

So we would calculate 32 (which is 9), then 33 (which is 27), and so on, until we reach a power of 3 that is greater than 1000. This sequence is 3, 9, 27, 81, 243, 729, and stops there because the next power, 37 or 2187, is beyond 1000.

write a word problem that involves finding the volume of a box draw the box solve the problem and explain how you found your answer

Answers

To solve for the volume of the soap box, the formula V = length x width x height is used, yielding a volume of 36 cubic inches, which matches the expected size for such an item.

Let's create a word problem: Susan has a small business making handmade soaps which she packages in rectangular boxes. She needs to calculate how much space her soaps will take during shipping. If one soap box has a length of 6 inches, a width of 3 inches, and a height of 2 inches, what is the volume of the soap box?

To solve this problem, we will use the formula for the volume of a rectangular box, which is V = length x width x height.

Plugging in the dimensions Susan provided, the volume V is calculated as 6 * 3 * 2, which equals 36 cubic inches.

Therefore, each soap box occupies a space of 36 cubic inches.

It's always important to check units to ensure the answer is reasonable. Since we measured in inches and are looking for a volume in cubic inches, the result of 36 cubic inches is appropriate for the size of a soap box.
