So you basically plot a point of the y axis on 7 then since the slope is -3x you have to go down 3 and to the right 1 and keep going then you have to do the same but opposite, go up 3 times and to the left 1 unit.

Divide £132 in the ratio 3:8

Answers

£132 in the ratio 3:8 as 36 and 96.

What is Ratio?

A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two quantities of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol. As a result, the ratio a/b has no units and is represented by the notation a: b.

Given:

Ratio= 3:8

Now, total = 3+ 8 = 11

So, First

£132 x 8/ 11

= 12 x 8

= 96

and, second

132 / 3/11

= 12 x 3

= 36

Hence, £132 in the ratio 3:8 as 36 and 96.

First you add 3 and 8. This equals 11.
£132 / 11 = £12
£12 x 3 = £36
£12 x 8 = £96
So your answer is £36:£96

Write the following proportion using colons. 7 is to 21 as 3 is to 9.a. 7:21 = 3:9
b. 7:3 = 21:9
c. 21:7 = 3:9
d. 7:21 = 9:3

Answers

Answer:

Option A.

Step-by-step explanation:

There are two fraction given in this question and we have to write the proportion using colon.

Visually fractions (7)/(21) and (3)/(9) are different but when we simplify these fractions we get the actual relation between them.

We simplify (7)/(21) first.

By dividing from 7 in the numerator and denominator we get

((7)/(7))/((21)/(7))=(1)/(3)

similarly we simplify the fraction (3)/(9)

By dividing numerator and denominator by 3

((3)/(3) )/((9)/(3) )=(1)/(3)

Now we can say that both the fractions are equal.

(7)/(21)=(3)/(9)=(1)/(3)

So the ratio will be 7 : 21 = 3 : 9

Option A. will be the answer.

The answer is 7:21 = 3:9.

What is the number in scientific notation? ​0.000013​ enter your answer in the box.

Answers

we have the number

0.000013

we know that

0.000013=(13)/(1000,000)= (13)/(10^(6))=13*10^(-6)=1.3*10^(-5)

therefore

the answer is

1.3*10^(-5)


move the decimal to the left

0.000013

move over five times

0.000013=1.3

then put 10^-5

and here's the answer

1.3 x 10^-5
