Question

I need help anyone,
I will thank u a lot

Answer 1

18=1/12

Explanation:

you take both fractions and multiply them to get 1/12

Answer 2

1). Option C

2). Option D

Explanation:

For the figure 1 attached,

It is given that Jeanne has spent $70.45 on the club for 12 months.

First month she paid monthly fees and an additional amount of $10.45.

Now we assume that the monthly fees of the club is $x

So in the first month Jeanne paid total amount = $(x + 10.45)

Further she pays only fees for 11 months.

Therefore, payment made for fees = 11x

Now we form the equation as

(x + 10.45) + 11x = 70.45

12x + 10.45 = 70.45

12x = 70.45 - 10.45

12x = 60

x =
`(60)/(12)=5`

Payments made in 12 months will be,

15.45, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5

Therefore, initial payment was 10.45 and rate of change of this function will be 5.

Option C is the answer.

In other part of the question we have to find the probability from two spinners.

Probability of getting B on spinner 1 will be

P₁ =
`\frac{\text{Number of alphabet B on the spinner}}{\text{Total number of sections on the spinner}}`

=
`(2)/(8)=(1)/(4)`

Similarly probability to get number 1 on spinner 2 will be

P₂ = \frac{2}{6}[/tex]

= \frac{1}{3}[/tex]

Now the probability of both the events =
`(1)/(4)* (1)/(3)=(1)/(12)`

Therefore, Option D is the answer.
