Step-by-step explanation:

Edith needs 10 meters of ribbon to make all 50 school spirit ribbons. To convert from centimeters to meters, we divide by 100. Therefore, 1,000 centimeters is equal to 10 meters.

To answer how many meters of ribbon Edith needs, we first need to understand the relationship between centimeters and meters. In one meter, there are 100 centimeters. Thus, to convert centimeters to meters, we can divide by 100.

Edith needs a total of 1,000 cm of ribbon. In order to convert this to meters, we would do the following calculation: 1000 cm ÷ 100 = 10 meters.

So, the correct answer is D. 10 m. Edith needs to buy 10 meters of ribbon from the fabric store. This is necessary to have enough ribbon to make all 50 school spirit ribbons that are each 20 cm long.

Answer:

10 cm.

Step-by-step explanation:

In order to better understand this question, I will attach an allusive image to the question.

Keep in mind that in this case the base of the triangle is equal to the radius of the base of the cone since the triangle rotates on its own axis, therefore the measurement of the base corresponds to 10 cm, therefore the radius measures 10 cm.

Answer:

The average weight of okapi  is 290 kg

The average weight of llama is 160 kg

Step-by-step explanation:

To solve the question, we are to resolve the word problem as follows;

Let the average weight of Okapi be X

The average weight of llamas be Y

X + Y = 450 and

3 Y = X + 190

Solving the above simultaneous equation, we have

X = 450 - Y

∴ 3·Y = 450-Y+190

4·Y =640

Y = 160 and X = 450 - 160 = 290

Therefore, the average weight of okapi  = 290 kg while the average weight of llama = 160 kg.

Answer: 3

Step-by-step explanation:

Nasim is making hot sauce. Nasim puts in chile peppers and tomatoes in a ratio of 1 to 3.

Assuming Nasim puts in 9 tomatoes, the number of chile peppers should she put will be:

Ratio of chile peepers to tomato= 1;3

Since she put 9 tomatoes, chile peppers= (1×9)/3 = 9/3 = 3.

For 1 chile peeper, there'll be 3 tomatoes.

For 3 chile pepper, thee will be 9 tomatoes.

Answer: She needs to add 3 chile peppers.

Step-by-step explanation:

The ratio of chile peppers to tomatoes is 1:3

this means that for each 3 tomatoes, she puts one chile pepper.

Then if she puts 9 tomatoes, this means that she puts 3 tomatoes 3 times.

And we know that for each 3 tomatoes she needs to add 1 chile pepper, then she needs to add 1 chile pepper 3 times:

3*1 = 3 chile peppers.

She needs to add 3 chile peppers.

Answer:

The answer is 32.

Step-by-step explanation:

Remember that order of operation is very important in this problem.

Substitute x for 3 and y for 2 in the equation.

When solving the first term, we must note that we have to square the 3 first before we multiply it by 4. So, 4(3)^2 is basically 36. To simplify the second term you just have to do 2*2, which is 4. 36-4=32, which is the answer.

Final answer:

The value of the expression 4x² - 2y when x = 3 and y = 2 is 32, found by substituting the values of x and y into the expression and simplifying.

Explanation:

To find the value of 4x² - 2y when x = 3 and y = 2, we need to substitute these values into the expression.

So, the value of the expression 4x² - 2y when x = 3 and y = 2 is 32.

Answer:

1 year:

The amount is $6695 and the interest is $195

2 years:

The amount is $6895.85 and the interest is $395.85.

The balance in the account at the end of 1 year would be approximately $6695 and at the end of 2 years would be approximately $6899.85 with an initial investment of $6500 with a 3% interest rate compounded annually.

The subject of this question is compound interest. When an amount of money is placed in an account with a certain interest rate, the amount grows over time. In this case, the initial investment is $6500 and the interest is compounded annually at a rate of 3%.

To calculate the total amount in the account after a certain period, you can use the following formula:

A = P(1 + r/n)^(nt)

A is the amount of money accumulated after n years, including interest. P is the principal amount (the initial amount), r is the annual interest rate (in decimal), n is the number of times that interest is compounded per year, and t is the time in years.

Applying this formula to the problem: for the end of first year, t=1, we will have:

A=6500(1 + 0.03/1)^(1*1) ≈ $6695

For the end of 2 years, t=2, we will get:

A=6500(1 + 0.03/1)^(1*2) ≈ $6899.85

Therefore, the balance in the account at the end of 1 year would be approximately $6695 and at the end of 2 years would be approximately $6899.85. Assume there are no withdrawals from the account during this period.

Final answer:

(Option D)Mitchell's stipend was  $506.02.

Explanation:

To find out how much Mitchell's stipend was, we can subtract the amount he spent on textbooks from the amount he had left at the end of the semester.

Let's assume Mitchell's stipend was X dollars.

He spent $429.17 on textbooks, so the remaining amount would be X - $429.17.

We know that he had $77.85 left, so we can set up the equation:

X - $429.17 = $77.85

Now, we can solve for X:

X = $77.85 + $429.17 = $506.02

So, Mitchell's stipend was $506.02. This corresponds to answer (Option D).

Hence the probability that are already owned are 0.943620

Step-by-step explanation:

Given:

No fo character sequences using either letter or digits had not been claimed=94696

To find :

What is probability that letter are already claimed ?

Solution:

We know that there are 26 alphabets  and digits are 0,1,2.. 9

Hence total will be of 36.

Now we are going to Arrange the sequence for all possible values

as there 4 characters we get ,each of them with 36 possible values

=36*36*36*36

=36^4

=1679616.

Now we have a sequence with 94696 character and digits are not claimed .

Its probability

=94696/1679616

=0.05637.

So the required probability will be ,

P(claimed)=1- P(Not claimed)

= 1-0.056379

=0.943620

Hence the probability that are already owned are 0.943620

The answer is C(n,r) = n!/[(n-r)!r!]

The formula for the following conditions is  [tex]C(n,r) = \dfrac{n!}{[(n-r)!r!]}[/tex]

We can use combinations for this case,

A total number of distinguishable things is m.

Out of those m things, k things are to be chosen such that their order doesn't matter.

This can be done in a total of

[tex]^mC_k = \dfrac{m!}{k! \times (m-k)!} ways.[/tex]

If the order matters, then each of those choice of k distinct items would be permuted k! times.

So, a total number of choices, in that case, would be:

[tex]^mP_k = k! \times ^mC_k = k! \times \dfrac{m!}{k! \times (m-k)!} = \dfrac{m!}{ (m-k)!}\\\\^mP_k = \dfrac{m!}{ (m-k)!}[/tex]

This is called the permutation of k items chosen out of m items (all distinct).

Step-by-step explanation:

Answer:

282°

Step-by-step explanation:

To find the length of VYX, use the Pythagorean theorem and set up an equation to solve for the length by squaring the lengths of the other sides and adding them together. Then, take the square root of the sum to find the length of VYX.

To find the length of VYX, we can use the Pythagorean theorem. In a right triangle, the square of the hypotenuse (VYX) is equal to the sum of the squares of the other two sides (VY and YX). Since we know VY (28 inches), we can solve for the length of VYX

Using the Pythagorean theorem: (VYX)2 = (VY)2 + (YX)2

Plugging in the values: (VYX)2 = (28)2 + (YX)2

Since the question asks for the length of VYX, we can take the square root of both sides to find the length of VYX: VYX = √[(28)2 + (YX)2]

Answer: the initial amount is $941.6

Step-by-step explanation:

We would apply the formula for determining compound interest which is expressed as

A = P(1 + r/n)^nt

Where

A = total amount in the account at the end of t years

r represents the interest rate.

n represents the periodic interval at which it was compounded.

P represents the principal or initial amount deposited

From the information given,

A = $1000

r = 1% = 1/100 = 0.01

n = 12 because it was compounded 12 times in a year.

t = 6 years

Therefore,.

1000 = P(1 + 0.01/12)^12 × 6

1000 = P(1 + 0.00083)^72

1000 = P(1.00083)^72

1000 = 1.062P

P = 1000/1.062

P = $941.6
