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.

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 total number of questions on the test is 40 (questions).

The power of 3 that are in range from 3 to 1000
(Need help on number 2)

Answers

it will be 3,9,27,81,243,729

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.

What is 4/7 of 49

Please explain why

Answers

4/7 of 49 = 28, the reason why is because if you divide 49 into 7 different groups, you will get 7 groups of 7(7x7=49). And if you take 4 of those groups, the answer is 28(7x4=28)
28 because if you divide 49 by 7 you would get 7 and then multiply it by 4. Then you get the answer of 28.

3x+1/5y=7. Solve for y.

Answers

3x+1/5y=7
-3x           -3x
1/5y=7-3x
-1      -1
5y=6-3x
---   -----
5       5

y = 6-3x
      ------
         5

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.

Maria knows there are 24 hours in one day and seven days in one week so she figured out that there are 168 hours and 1 week is her answer reasonable explain why or why not

Answers

Yes, she multiplied 24 (the hours in a day) by 7 (days in a week), and the answer is 168. 
This is correct because you have to multiply 24 by 7 which gets you 168. You have to multiply because there is 24 hours in a day, and 7 days a week.

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.

14. The percentage of change from 35 birds to 45 birds is 59%.

15. The percentage of change from 60 inches to 38 inches is 37%.

17. 1/6 years.

18. 1/4 years.

19. 1/3 years.

20. 1/2 years.

What is a percentage?

In Mathematics, a percentage is any number that is expressed as a fraction of hundred (100).

Part 14.

Mathematically, percentage increase can be calculated by using the following mathematical equation:

Percentage increase = (Final value - Initial value)/Initial value × 100

Percentage increase = (45 - 35)/35 × 100

Percentage increase = 10/35 × 100

Percentage increase = 28.57 ≈ 29%.

Part 15.

Mathematically, percentage decrease can be calculated by using the following mathematical equation:

Percentage decrease = (Final value - Initial value)/Final value × 100

Percentage decrease = (60 - 38)/60 × 100

Percentage decrease = 22/60 × 100

Percentage decrease = 36.67 ≈ 37%.

Note; 1 year is equal to 12 months.

In order to express each number of months in years, we would divide the number of month by 12;

Part 17.

Time = 2/12

Time = 1/6 years.

Part 18.

Time = 3/12

Time = 1/4 years.

Part 19.

Time = 4/12

Time = 1/3 years.

Part 20.

Time = 6/12

Time = 1/2 years.

3/5 pt of juice is poured into 6 glasses.How much juice is in each glass?

Answers

Each glass contains 1/10 pt of juice when 3/5 pt of juice is evenly divided into 6 glasses.

To determine how much juice is in each glass when 3/5 pt of juice is poured evenly into 6 glasses, one must divide the total amount of juice by the number of glasses. This is a basic division problem often encountered in converting customary units in real-world situations.

First, convert the pint (pt) measurement to a more convenient unit if needed. In this case, we can keep it in pints since the division is straightforward. Next, divide the 3/5 pt of juice by 6.

Calculate the amount of juice in each glass: 3/5 ÷ 6 = 3/5 × 1/6 = 3/30 = 1/10.

Convert the fraction to pint measurement if necessary: 1/10 pt.

So each glass would contain 1/10 pt of juice.

here, you need to distribute the "20" to the inside of your parentheses. you'll be multiplying 20 and -1.5 first:

-30r

then 20*0.75 second:

-30r + 15 is your expanded expression. you can't combine like terms any further.

Answer:

-30r + 15

Step-by-step explanation:

We have been given that

20(−1.5r+0.75)

Use the distributive property a(b+c)=ab+ac.

20×(−1.5r)+20×0.75

Multiplying, we get

-30r +15

These two are not like terms. Hence , we cannot combine them.

Therefore, we cannot simplify it more.

Hence, the simplified expression is -30r + 15

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.
