Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.

For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

The cost of A package of 8 rechargeable batteries = $12.

Now,

Since, The cost of A package of 8 rechargeable batteries = $12.

So, The cost of A package of 1 rechargeable batteries = $12/8

Hence, The cost of A package of 20 rechargeable batteries is,

= $12/8  x 20

= $30

Thus, The cost of 20 rechargeable batteries will be $30.

What single percentage change is equivalent to a 11% decrease followed by a 15% decrease?

Answers

Answer:

Read the explanation to find your answer.

Step-by-step explanation;  

First, work out the difference (decrease) between the two numbers you are comparing. Next, divide the decrease by the original number and multiply the answer by 100.

Answer:

The answer is 75.65%.

Step-by-step explanation:

Since we are decreasing the percentages, we will first take 100 and subtract 11% from it, which is 89%.  Now take 15% and turn it into decimal form, and we get 0.15.  Then multiply 0.15 by 89 and we get 13.35.  Now we have our number 13.35, we will subtract 89 from 13.35, and we get 75.65%.  Therefore, the answer is 75.65%.

if f(x)=2x+1 and g(x)=x2 find fg(3)​

Answers

Given:

The functions are:

[tex]f(x)=2x+1[/tex]

[tex]g(x)=x^2[/tex]

To find:

The value of [tex]fg(3)[/tex].

Solution:

We have,

[tex]f(x)=2x+1[/tex]

[tex]g(x)=x^2[/tex]

Substitute [tex]x=3[/tex] in each function.

[tex]f(3)=2(3)+1[/tex]

[tex]f(3)=6+1[/tex]

[tex]f(3)=7[/tex]

And,

[tex]g(3)=(3)^2[/tex]

[tex]g(3)=9[/tex]

We know that, product of two functions is defined as:

[tex]fg(x)=f(x)\times g(x)[/tex]

Using this rule, we get

[tex]fg(3)=f(3)\times g(3)[/tex]

[tex]fg(3)=7\times 9[/tex]

[tex]fg(3)=63[/tex]

Therefore, the value of [tex]fg(3)[/tex] is 63.

longer piece of cable?
F.:.6
G. 13
H. 15
J. 24
K. 26

Answers

Answer:

the length of the  longer piece of cable is 24 ft

Step-by-step explanation:

shor piece = s

Long piesce = s+9

s + s+9= 39

2s = 30

s = 15

short = 15

15 +9 = 24

long = 24

15+24 = 39

Answer:

24 feets

Step-by-step explanation:

let the shorter cable be x feets

so the longer cable will be 9 plus the shorter cable which is (9 + x) feets

Total length = Longer cable + shorter cable 39 = (9 + x) + x

39 = 9 + 2x2x = 39 - 9 2x = 30

[tex]x \: = \: \frac{30}{2} \\ x = 15feets[/tex]

But the longer cable is (9 + x)So longer cable = 9 + 15

Longer cabl = 24 feets

A city council consists of sevenseven Democrats and eighteight Republicans. If a committee of fivefive people is​ selected, find the probability of selecting twotwo Democrats and threethree Republicans.

Answers

Answer:

The probability of selecting two Democrats and three Republicans is 10.7%.

Step-by-step explanation:

Given that a city council consists of seven Democrats and eight Republicans, if a committee of five people is selected, to find the probability of selecting two Democrats and three Republicans the following calculation must be performed:

7 = 100

2 = X

2 x 100/7 = X

28.57 = X

8 = 100

3 = X

3 x 100/8 = X

37.5 = X

0.2857 x 0.375 = X

0.107 = X

0.107 x 100 = 10.7

Therefore, the probability of selecting two Democrats and three Republicans is 10.7%.
