what is 5 divided by 50

Answers

Answer:

50 divided by 5: 10.

5 divided by 50: 0.1

Step-by-step explanation:

Here we will show you step-by-step with detailed explanation how to calculate 50 divided by 5 using long division.

Before you continue, note that in the problem 50 divided by 5, the numbers are defined as follows:

50 = dividend

5 = divisor

Step 1:

Start by setting it up with the divisor 5 on the left side and the dividend 50 on the right side.

Step 2:

The divisor (5) goes into the first digit of the dividend (5), 1 time(s). Therefore, put 1 on top.

Step 3:

Multiply the divisor by the result in the previous step (5 x 1 = 5) and write that answer below the dividend.

Step 4:

Subtract the result in the previous step from the first digit of the dividend (5 - 5 = 0) and write the answer below.

Step 5:

Move down the 2nd digit of the dividend (0)

Step 6:

The divisor (5) goes into the bottom number (0), 0 time(s). Therefore, put 0 on top.

Step 7:

Multiply the divisor by the result in the previous step (5 x 0 = 0) and write that answer at the bottom.

Step 8:

Subtract the result in the previous step from the number written above it. (0 - 0 = 0) and write the answer at the bottom.

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 50 divided by 5 OR 5 divided by 50 calculated using Long Division is:

50 divided by 5: 10.5 divided by 50: 0.1

is the population of cats on another island whose cat population was originally 11,000 but is doubling every 14 months. (t is time in months.)

Answers

Answer:

P = 11,000(2)^t/11

Step-by-step explanation:

The formula is given as:

P = Po(2)^t/d

Where

Po = Initial population = 11,000

t = time in months

d = doubling time = 11 months

Hence,

P = 11,000(2)^t/11

Hence, the population of cats is given by the equation:

P = 11,000(2)^t/11

8x = 6x + 6

2x = 6

x = 3

-----

1st 2x = 6

2nd: 2x+2 = 8

Step-by-step explanation:

The two consecutive even integers such that four times the first equals three times the second is 6 and 8.

What is an integer ?

An integer is a number which has no decimal part.

According to the given question we have to find two consecutive even integers such that four times the first equals three times the second.

Let, the first even integer to be x.

∴ The second integer will be (x+2).          [ As every consecutive even                                                                                    

                                                                            integers comes after 2 digits]

Now, Four times the first equals three times the second which is

4x = 3(x+2)

4x = 3x + 6.

4x - 3x = 6

x = 6.

∴ The even integer is 6 and the second integer is 8.

The sick days of employees every two years in a company are normally distributed with a population standard deviation of 7 days and an unknown population mean. If a random sample of 20 employees is taken and results in a sample mean of 21 days, find a 95% confidence interval for the population mean.

Answers

Step-by-step explanation:

Let [tex]$X_1, X_2, X_3,$[/tex] . . . ,Xn be the random sample of n employee's sick days. It is given that the random samples follows the  Normal distribution along with standard deviation of 7 days. Let

[tex]X_i\sim N(\mu ,7)[/tex]

[tex]\bar{X} =\frac{1}{n}\Sigma X_i\sim N(\mu,\frac{7}{\sqrt n})[/tex]

or   [tex]Z=\frac{\bar{X}-\mu}{7 /\sqrt n} \sim N(0,1)[/tex]

So,

[tex]P(-Z_{\alpha /2} \leq Z\leq Z_{\alpha /2} ) = 1- \alpha[/tex]

[tex]P(-Z_{\alpha /2} \leq \frac{\bar{X}- \mu}{7 / \sqrt n}\leq Z_{\alpha /2} ) = 1- \alpha[/tex]

[tex]P(\bar{X}-\frac{7}{\sqrt n} Z_{\alpha / 2} \leq \mu \leq \bar{X}+\frac{7}{\sqrt n} Z_{\alpha / 2} ) = 1- \alpha[/tex]

Therefore, the confidence interval of the population mean for α = 0.05 is

= [tex]P(\bar{X}-\frac{7}{\sqrt n} Z_{\alpha / 2} , \bar{X}+\frac{7}{\sqrt n} Z_{\alpha / 2} )[/tex]

= [tex]P(21-\frac{7}{\sqrt 20} Z_{0.05 / 2} , 21+\frac{7}{\sqrt 20} Z_{0.05 / 2} )[/tex]

to nearest hundreth.
12 cm
7 cm​

Answers

Answer:

The perimeter of the shape below is 44.48cm

Step-by-step explanation:

To calculate the perimeter of this figure we have to add

7cm + 12cm + 7cm + ( perimeter of semicircle)

To calculate the perimeter of the semicircle we have to use the following equation

d = 12cm

r = d/2 = 12cm/2 = 6cm

c = perimeter of semicircle

r = radius = 6cm

π = 3.14

c = π * r

we replace with the known values

c = * 3.14 * 6cm

c = 18.84cm

The perimeter of the semicircle is 18.84cm

Now that we have this value we can calculate the perimeter of the figure

7cm + 12cm + 7cm + ( 18.84cm ) = 44.48cm

The perimeter of the figure is 56.84 cm

What is the area of the rectangle?

The formula for area is equal to the product of the length and breadth of the rectangle. Whereas when we speak about the perimeter of a rectangle, it is equal to the sum of all its four sides.

Given here: A semicircle on top of the rectangle with dimensions 12, 7 cm respectively .

Thus perimeter of the figure = perimeter of semi circle+ perimeter of rectangle

∴ 3.14×6+2(12+7)=56.84 cm

Hence, The perimeter of the figure is 56.84 cm

​6 2/3÷1/5​ Express your answer as a mixed number in simplest form. Enter your answer in the box.

Answers

Answer:

33 1/3

Step-by-step explanation:

1. First, you want to make 6 into a fraction with a bottom/denominator of 3 to make adding 6 and 2/3 easier.  So, to make 6 into a fraction with a denominator of 3 , you multiply 6 by 3 to get 18.  The 18 is the numerator (top of the fraction) and 3 is the denominator (the bottom).  So now you have 18/3+2/3 divided by 1/5.

2. Now, add the 18/3 and the 2/3 to get 20/3 divided by 1/5.

3. After this, you want to divide.  To divide fractions, you use Keep, Change, Flip (KCF).  To do this, keep the 20/3 the same, change the division sign to multiplication, and flip the 1/5 to 5/1.  So, now you have 20/3 multiplied by 5/1.

4. Simplify this by multiplying 20 by 5 and 3 by 1 to get 100/3.

5. Now we have to create 100/3 into a mixed number.  To do this, we know that 33 multiplied by 3 is 99, which is as close as we can get to 100 without going over.  This means that we can make 100/3 into 33 and 1/3.  

Hope this helps! :) If you could give me Brainliest that would be super helpful!

Answers

Answer:

6 is 100 times 0.06

0.06 is 10 times 0.006

60 is 1/100 of 6,000

Step-by-step explanation:

Since 6/100 is equal to 0.06, we can say that 6 is the result of multiplying 0.06 by one hundred (0.06 x 100 = 6).

On the other hand, since 0.06 / 10 is equal to 0.006, it is correct to say that 0.006 x 10 is equal to 0.06 (0.006 x 10 = 0.06).

Finally, 60 is one hundredth of 6000, since multiplying 60 x 100 the result is 6,000 (6,000 / 100 = 60).
