Step-by-step explanation:

if there are twins born every 250 births take your large number (2,750) and divide it by 250 to get your answer

There are 11 pairs of twins at a school with 2750 students.

Repetitive subtraction is the process of division. It is the multiplication operation's opposite. It is described as the process of creating equitable groups. When dividing numbers, we divide a larger number down into smaller ones such that the larger number obtained will be equal to the multiplication of the smaller numbers.

Given identical  twins happen once in 250 births,

total number of students in school = 2,750

to find the pair of twins divide the total number of students by 250

= 2750/250 = 11

Hence there are  11 pairs of twins in 2,750 students.

A rectangle.

Step-by-step explanation:

The 2 ends of the rectangular prism are squares while the other 4 sides are rectangles. A cross section parallel to the base would be a rectangle as the base is a rectangle as well.

(6) The value of [tex]\sqrt{64}[/tex] is 8.

(7) The value of [tex]-\sqrt{31}[/tex] is -5.6

(8) The value of [tex]-\sqrt{16}[/tex] is -4

Explanation:

(6) The expression is [tex]\sqrt{64}[/tex]

Since, 64 is a perfect square, this can be written as [tex]8 \times 8[/tex].

Thus, the expression can be written as

[tex]\sqrt{64}=\sqrt{8 \times 8}=\sqrt{8^{2} }[/tex]

The square root gets cancelled. Thus, we have,

[tex]\sqrt{64}=8[/tex]

Thus, the value of [tex]\sqrt{64}[/tex] is 8.

(7) The expression is [tex]-\sqrt{31}[/tex]

Since, 31 is not a perfect square and solving the expression using a calculator, we get,

[tex]-\sqrt{31}=-5.56776[/tex]

Rounding off to the nearest tenth, we get,

[tex]-\sqrt{31}=-5.6[/tex]

Thus, the value of [tex]-\sqrt{31}[/tex] is -5.6

(8) The expression is [tex]-\sqrt{16}[/tex]

Since, 16 is a perfect square, this can be written as [tex]4\times 4[/tex]

Thus, the expression can be written as

[tex]-\sqrt{16}=-\sqrt{4\times 4}=-\sqrt{4^{2} }[/tex]

The square root gets cancelled. Thus, we have,

[tex]-\sqrt{16}=-4[/tex]

Thus, the value of [tex]-\sqrt{16}[/tex] is -4.

Answer:

Step-by-step explanation:

3,-12,15,-21

The product 3 x [1 -4 5 -7] of [ -3  12  -15  21 ]

In mathematics, when we multiply a scalar (a single number) by a vector, the result is a new vector where each element of the original vector is multiplied by that scalar.

In this case, we have the scalar 3 and the vector [1  -4  5  -7].

1. Multiply each element of the vector by the scalar 3:

  3 x 1 = 3  

  3 x (-4) = -12  

  3 x 5 = 15  

  3 x (-7) = -21

2. Arrange the results in order:

  -3  12  -15  21

So, the product of 3 and the vector [1  -4  5  -7] is the new vector [-3  12  -15  21].

In this process, we essentially scaled each component of the original vector by a factor of 3, either increasing or decreasing the magnitude based on the sign of the original component.

Answer:

Part a) 3 inches

Part b) Yes, her scale model drawing will fit on the piece of paper 8.5 by 7 inches

Step-by-step explanation:

we know that

The scale drawing is

[tex]1\ inch:2\ feet[/tex]

That means

1 inch in the model represent 2 feet in the actual

Part a) What is the length of the garden in her model?

we know that

The length of the garden is 6 feet in the actual

so

Find out the length of the garden in her model, using proportion

[tex]\frac{1}{2}\ \frac{in}{ft}=\frac{x}{6}\ \frac{in}{ft}\\\\x=6/2\\\\x=3\ in[/tex]

Part b) If the width is 5 inches for the scale model and the scale is still 1 inch to 2 feet, will her scale model drawing fit on a piece of paper that is 8.5 inches by 7 inches? Why or why not?

we know that

The model width is described as 5 inches. Both the 3-inch length and the 5-inch width are less than the 8.5 inch and 7 inch dimensions of the paper Kelly is using.

therefore

She can easily draw her model on that size paper.

Answer:

1/8, 1/4, 3/8, 9/16, 3/4, 1

Step-by-step explanation:

The fractions have been arranged in order from smallest to largest as 1/8< 1/4< 3/8< 9/16< 3/4< 1.

Fractions with different denominators can be compared by making the denominators the same. For example, take 1/4 and 1/2. The LCM of these fractions is 4. Now we can alter the fractions so that they have the same denominators as follows:

1/4 and 2/4

We can see that 2/4 is greater than 1/4.

The given fractions are: 3/4, 1/8, 9/16, 1, 1/4, 3/8

The lowest common multiple of these fractions is 16.

We can convert the fractions as shown below:

12/16< 2/16< 9/16< 16/16< 4/16< 6/16

Now we can arrange them in ascending order easily as shown below:

2/16, 4/16, 6/16, 9/16, 12/16, 16/16

or 1/8< 1/4< 3/8< 9/16< 3/4< 1

Therefore, we have arranged the fractions in order from smallest to largest as 1/8< 1/4< 3/8< 9/16< 3/4< 1.

Got it correct on TIME4LEARNING

Eva has $20.00, Justin has $27.50 and Emma has $15.50

Step-by-step explanation:

The given is:

We need to find how much money each person has

Assume that Eva has $x

∵ Eva has $x

∵ Justin has $7.50 more than Eva

- Add 7.50 to x

∴ Justin has = x + 7.50

∵ Emma has $12 less than Justin

- Subtract 12 from (x + 7.50)

∴ Emma has = x + 7.50 - 12 = x - 4.50

∵ Together, they have a total of $63.00

- Add x , (x + 7.50) and (x -4.50), then equate the sum by 63.00

∴ x + (x + 7.50) + (x - 4.5) = 63.00

- Add like terms

∴ (x + x + x) + (7.5 - 4.5) = 63.00

∴ 3x + 3 = 63.00

- Subtract 3 from both sides

∴ 3x = 60.00

- Divide both sides by 3

∴ x = 20.00

Substitute x by 20.00 in each expression above

∴ Eva has = $20.00

∴ Justin has = 20.00 + 7.50 = $27.50

∴ Emma has = 20.00 - 4.50 = $15.50

Eva has $20.00, Justin has $27.50 and Emma has $15.50

26/100 which is simplified to 13/50

Step-by-step explanation:

you have to get equal denominators so multiply 2/10 by 10 on top and bottom to get 20/100 then you can add 6/100 plus 20/100 which is 26/100 . denominators stay the same 26/100 can be simplified to 13/50

The sum of 2/10 and 6/100 is 13/50.

To find the sum of 2/10 and 6/100, we'll first find a common denominator and then add the fractions together.

The common denominator for 10 and 100 is 100, as it is the smallest multiple that both denominators can evenly divide into.

Now, we'll rewrite both fractions with the common denominator of 100:

2/10 = (2/10) * (10/10) = 20/100

6/100 = 6/100

Now that both fractions have the same denominator, we can add them together:

20/100 + 6/100 = (20 + 6)/100 = 26/100

Now, we have the sum of the fractions as 26/100. To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 2:

(26 ÷ 2) / (100 ÷ 2) = 13/50

Answer:

Therefore (28,45,53) is a Pythagorean triple.

Step-by-step explanation:

A Pythagorean triple consists of three positive integers a,b and c such that

a²+b²=c²

1.

3²+6²=45  and 12²=144

∴3²+6²≠144

Therefore (3,6,12) is not a Pythagorean triple.

2.

8²+16²= 330   and 32²= 1024

∴8²+16²≠32²

Therefore (8,16,32) is not a Pythagorean triple.

3.

12²+34²=1024 and   34²=5611

∴12²+34²≠34²

Therefore (12,34,30) is not a Pythagorean triple.

4.

28²+45²=2809   and   53²=2809

∴28²+45²=53²

Therefore (28,45,53) is a Pythagorean triple.

Hours Spent at Water Park

     Hours     Tally

       4              4

       5              5

       6              3

       7              4

These data could be the results of a survey whose target was to detemine how many hours people spent at a water park.

The size of the sample should be the number of tally, which is 4 + 5 + 3 + 4 = 16.

And the question most likely was made at the exit of a water park, when the people were leaving the park.

Thus, the statistical question could be How much time do people spend in the water park?

It is a statistical because the survey is made to a sample of the people who went to the water park instead to all the people. All the people who go to the water park is the population about whom you want to determine how much time they spend in the water park, but,since it is impossible to survey all the people, you need to survey a sample.

The resulting values from a sample are named statistical. The values for an entire population are named parameters. A statistical permits to draw conclusions for populations using just one or more samples, which should be random samples.

Answer:

“How many hours did you spend at the water park today?” It is statistical because the responses will vary among individuals and the responses will be numeric.
