Can you explain how to solve this problem

iVinArrow [24]

Answer:

Step 1:

Start by setting it up with the divisor 10 on the left side and the dividend 179 on the right side like this:

1 0 ⟌ 1 7 9

Step 2:

The divisor (10) goes into the first digit of the dividend (1), 0 time(s). Therefore, put 0 on top:

0

1 0 ⟌ 1 7 9

Step 3:

Multiply the divisor by the result in the previous step (10 x 0 = 0) and write that answer below the dividend.

0

1 0 ⟌ 1 7 9

0

Step 4:

Subtract the result in the previous step from the first digit of the dividend (1 - 0 = 1) and write the answer below.

0

1 0 ⟌ 1 7 9

- 0

1

Step 5:

Move down the 2nd digit of the dividend (7) like this:

0

1 0 ⟌ 1 7 9

- 0

1 7

Step 6:

The divisor (10) goes into the bottom number (17), 1 time(s). Therefore, put 1 on top:

0 1

1 0 ⟌ 1 7 9

- 0

1 7

Step 7:

Multiply the divisor by the result in the previous step (10 x 1 = 10) and write that answer at the bottom:

0 1

1 0 ⟌ 1 7 9

- 0

1 7

1 0

Step 8:

Subtract the result in the previous step from the number written above it. (17 - 10 = 7) and write the answer at the bottom.

0 1

1 0 ⟌ 1 7 9

- 0

1 7

- 1 0

7

Step 9:

Move down the last digit of the dividend (9) like this:

0 1

1 0 ⟌ 1 7 9

- 0

1 7

- 1 0

7 9

Step 10:

The divisor (10) goes into the bottom number (79), 7 time(s). Therefore put 7 on top:

0 1 7

1 0 ⟌ 1 7 9

- 0

1 7

- 1 0

7 9

Step 11:

Multiply the divisor by the result in the previous step (10 x 7 = 70) and write the answer at the bottom:

0 1 7

1 0 ⟌ 1 7 9

- 0

1 7

- 1 0

7 9

7 0

Step 12:

Subtract the result in the previous step from the number written above it. (79 - 70 = 9) and write the answer at the bottom.

0 1 7

1 0 ⟌ 1 7 9

- 0

1 7

- 1 0

7 9

- 7 0

9

You are done, because there are no more digits to move down from the dividend.

The answer is the top number and the remainder is the bottom number.

Therefore, the answer to 179 divided by 10 calculated using Long Division is:

17

9 Remainder

The weekly incomes of a large group of executives are normally distributed with a mean of $2,000 and a standard deviation of $10

cestrela7 [59]

Let X be the weekly incomes of a large group of executives. The weekly incomes of a large group of executives follows Normal distribution with mean $2000 and standard deviation $100.

μ =2000, σ =100

We have to find z score for income $2100 i.e x=2100

Z = $\frac{x-mean}{standard deviation}$

= $\frac{2100 - 2000}{100}$

Z = 100/100

Z = 1

The z score for income $2100 is 1

Solve the equation for<br> x 3/4(x+21) = 10.5 <br> x =

MrRa [10]

<h3>✍️ Answer:</h3><h3> $x=-\frac{294}{13}$ </h3>

✽✽✽✽

$\frac{x\cdot \:3}{4\left(x+21\right)}=10.5$

$\mathrm{Multiply\:both\:sides\:by\:}4\left(x+21\right)$

$\frac{x\cdot \:3}{4\left(x+21\right)}\cdot \:4\left(x+21\right)=10.5\cdot \:4\left(x+21\right)$

$3x=42\left(x+21\right)$

$3x=42x+882$

$\mathrm{Subtract\:}42x\mathrm{\:from\:both\:sides}$

$3x-42x=42x+882-42x$

$-39x=882$

$\mathrm{Divide\:both\:sides\:by\:}-39$

$\frac{-39x}{-39}=\frac{882}{-39}$

$x=-\frac{294}{13}$

The tape diagram represents an equation,<br> 1.75<br> Write an equation to represent the image.

rjkz [21]

Answer:

$5n=1.75$

Step-by-step explanation:

Given: tape diagram

To find: an equation to represent the image

Solution:

In the image, the area of the tape diagram indicating 1.75 is equal to the sum of areas of all the five parts in the diagram such that each part indicates n.

So, according to the given information, the equation is $5n=1.75$ .

Here, we have assumed that 1.75 represents an area of the first rectangle, and n represents the area of each of the small rectangle.
