Dez was called to solve a problem on the whiteboard in class. His work is shown below.

0.8 × Four-fifths

8/10 × 4/5 = 32/5

StartFraction 32 over 5 EndFraction = 6Two-fifths

Is the answer shown reasonable?

(A) The answer is reasonable because 0.8 was converted to an equivalent fraction.
(B) The answer is reasonable because it is greater than both factors.
(C) The answer is not reasonable because 4/5 of a number should be less than the number.
(D)The answer is not reasonable because StartFraction 32 over 5 EndFraction does not equal 6Two-fifths.

10 divided by 3 long division

Answers

Okay so the first thing we need to do is clarify the terms so that you know what each part of the division is:

The first number, 10, is called the dividend.The second number, 3 is called the divisor.

What we'll do here is break down each step of the long division process for 10 divided by 3 and explain each of them so you understand exactly what is going on.

10 divided by 3 step-by-step guideStep 1

The first step is to set up our division problem with the divisor on the left side and the dividend on the right side, like we have it below:

  __

3| 10

Step 2

We can work out that the divisor (3) goes into the first digit of the dividend (1), 0 time(s). Now we know that, we can put 0 at the top:

   _0_

3 | 10

Step 3

If we multiply the divisor by the result in the previous step (3 x 0 = 0), we can now add that answer below the dividend:

 _0_

3 | 10

    0

Step 4

Next, we will subtract the result from the previous step from the second digit of the dividend (1 - 0 = 1) and write that answer below:

 ___

3 | 10

- 0

__

1

Step 5

Move the second digit of the dividend (0) down like so:

 __0_

3 | 10

 - 0

-----------

10

Step 6

The divisor (3) goes into the bottom number (10), 3 time(s), so we can put 3 on top:

 __03_

3 | 10

- 0

___

10

Step 7

If we multiply the divisor by the result in the previous step (3 x 3 = 9), we can now add that answer below the dividend:

 _03_

3 | 10

- 0

__

10

 9

Step 8

Next, we will subtract the result from the previous step from the third digit of the dividend (10 - 9 = 1) and write that answer below:

  __03_

3 | 10

- 0

__

10

-9

_

1

So, what is the answer to 10 divided by 3?

Your answer is the top number, and any remainder will be the bottom number. So, for 10 divided by 3, the final solution is:

3 - Remainder 1Extra calculations for you:Using a calculator, if you typed in 10 divided by 3, you'd get 3.3333.You could also express 10/3 as a mixed fraction: 3 1/3If you look at the mixed fraction 3 1/3, you'll see that the numerator is the same as the remainder (1), the denominator is our original divisor (3), and the whole number is our final answer (3).

If the mean of a data set is 100 and almost all the data is from 40 to 160, what is a good approximation of the variance?
A) 120
B) 20
C) 900
D) 400
E) none of the above

Answers

A.) 120

The variance is the range of a data set, which shows how spread out numbers are. To get the variance, we take the last number and subtract it from the first number. 160-40=120. Therefore, there is 120 numbers between 40 to 160.

-X + 2y= -3 and -8x — 3y= -5

Answers

Answer:

x=1, y=-1. (1, -1).

Step-by-step explanation:

-x+2y=-3

-8x-3y=-5

----------------

-8(-x+2y)=-8(-3)

-8x-3y=-5

------------------------

8x-16y=24

-8x-3y=-5

-----------------

-19y=19

y=19/-19

y=-1

-x+2(-1)=-3

-x-2=-3

-x=-3+2

-x=-1

x=1

(1, -1)

Answer:

x = 1, y = -1

or as an ordered pair, (1, -1).

Step-by-step explanation:

  -x  + 2y = -3

-8x — 3y = -5

Multiply first equation by -8:

8x - 16y = 24

Add this equation to the second equation:

-19y = 19

y = -1.

Plug y = -1 into the second equation:

-8x - 3(-1) = -5

-8x + 3 = -5

-8x = -8

x = 1.

Enter a number in the box so that the equation will have no solution.

What is the percent increase of 24 to 32?

Answers

Answer:

8%???????????????????????

I will show you how calculate the Percent Change from 24 to 32.

Basically, we are trying to find the change from 24 to 32 in terms of percent. We do this in three steps:

1) Find the difference between 24 and 32 as a number.

2) Divide the result from Step 1 by the starting number 24.

3) Multiply the result from Step 2 by 100 to get it in terms of percent.

The three steps above can be made into a formula. So, to find the percent change from 24 to 32, we use this formula:

((Y-X)/X)*100 = Percent Change

X is the starting number 24, and Y is the ending number 32 that it changed to. When we enter these numbers into the formula, we get:

((32-24)/24)*100 = 33.33%

So, the answer to the question "What is the Percent Change from 24 to 32?" is:

33.33%

Note: All percent answers are rounded to the nearest two decimals if necessary.

5.37 + x =12.89 explanation please it’s two step equation

Answers

Answer:

7.52

Step-by-step explanation:

5.37 + x = 12.89

In order to solve this equation, we must isolate the variable, x.

1.) To do this, subtract 5.37 on both sides of the equation.

5.37 + x = 12.89

-5.37         -5.37

x = 7.52

Therefore, x = 7.52

A dollar bill is about 0.00011 meter thick. What is this thickness in scientific notation?

Answers

Answer:

1.1 * 10 ^ -3

Step-by-step explanation:

Given the value of the thickness of a dollar bill to be 0.00011 metre .

The standard scientific Notation is expressed as A * 10 ^ n

A is any value between 1 and 10 where n is any Integer .

0.00011 = 11 / 100000

0.00011 = 11 / 10000

0.00011 = 11 *1 / 1000

0.00011 = 11 * 0.0001

0.00011 = 1.1 * 0.001

0.0011 = 1.1 * 10 ^ -3
