What are the dimensions of the rectangle?

Answers

Answer 1

Answer: the dimensions would be 18 by 5.5. because you know the area is 99, and you know the area formula is length multiplied by width, you set the dimensions to 99, and continue to solve for x. then you plug the x value into the length’s dimension to get 18.

Which of the following represents the prime factorization of 72?

Answers

If you would like to write the prime factorization of 72, you can do this using the following steps:

72 / 2 = 36
36 / 2 = 18
18 / 2 = 9
9 / 3 = 3
3 / 3 = 1

72 = 2 * 2 * 2 * 3 * 3 = 2^3 * 3^2

The correct result would be 2 * 2 * 2 * 3 * 3.

Answer:

2^3 3^2

Evaluate. f(x) = 2x - 1, f(2)

Answers

Answer:

f(2) = 3

Step-by-step explanation:

Substitute 2 for x, and evaluate the expression.

f(x) = 2x - 1

f(2) = 2(2) - 1

f(2) = 4 - 1

f(2) = 3

answer: so, f(x)=2(2)-1
which will be =3 so answer is 3

Rectangle HIJK is dilated to form rectangle TUVW. What corresponding side is proportional to segment JK? Type the answer in the box below.

Answers

Answer: VW

Step-by-step explanation:

By the property of dilation,

If Rectangle HIJK is dilated to form rectangle TUVW,

Then Rectangle HIJK is similar to TUVW,

Thus, by the property of similarity,

The corresponding sides of HIJK and TUVW are proportional to one another.

Since, segment JK is corresponding to segment VW,

⇒ Segment JK is proportional to segment VW.

Answer:

VW

Joe says that the product of 4-digit number and a 1-digit number is always a 4-digit number. Does Jose's statement make sense?

Answers

We cannot say that the product of 4-digit number and a 1-digit number is always a 4-digit number.

Joe's statement does not make sense.

Given :

Joe says that the product of 4-digit number and a 1-digit number is always a 4-digit number.

Lets take an example and analyze Joe's statement

Let the 4 - digit number is 2131

and a one digit number is 5

Lets multiply it

$2131 \cdot 5=10665$

We can see the the result is a 5-digit number

We cannot say that the product of 4-digit number and a 1-digit number is always a 4-digit number.

Joe's statement does not make sense.

The correct answer is:

No.

Explanation:

The number of digits in the product depends completely on what digits are being multiplied. For instance, multiplying 2222 by 4 would result in a 4-digit number, 8888. However, if you multiply by 5, since 5(2) = 10, this will change the number of digits in the answer.

Provide an appropriate response.39) Find a set of 7 scores that has the same mean but a smaller standard deviation than the
set {65, 71, 77, 80, 82, 90, 96}.

Answers

You don't even have to look up the definition of 'standard deviation'. You only
have to remember that 'smaller standard deviation' means 'less spread-out'.

First, let's find the mean (average). It's not supposed to change:

1/7th of (65 + 71 + 77 + 80 + 82 + 90 + 96) = 561/7 = 80 and 1/7 .

Now, just pick 7 scores that total 561 and are all bunched up.

The easiest way would be 80, 80, 80, 80, 80, 80, 81 .
But that's so easy that it feels like cheating.

Let's say 77, 78, 79, 80, 81, 82, and 84 .
