lesantik [10]

Answer:

t(g)= -4g + 20

Step-by-step explanation:

James is playing his favorite game at the arcade. After playing the game 3 times, he has 8 tokens remaining. He initially had 20 tokens, and the game costs the same number of tokens each time. The number tt of tokens James has is a function of gg, the number of games he plays

Solution

Let

g=No. of games James plays

t= No. of tokens James has.

Find the slope using

y=mx + b

Where,

m = Slope of line,

b = y-intercept.

Before James started playing the games, he has a total of 20 tokens.

That is, when g=0, t=20

After James played the games 3 times, he has 8 tokens left

That is, when g=3, t=8

(x,y)

(0,20) (3,8)

m=y2-y1 / x2-x1

=(8-20) / (3-0)

= -12 / 3

m= -4

Slope of the line, m= -4

y=mx + b

No. of tokens left depend on No. of games James plays

t is a function of g.

t(g)

t(g)= -4g + 20

A customer borrowed 2000 and then further 1000 both repayable in 12 months .What would he have saved if he had taken out one loa
creativ13 [48]

Answer:

No savings

Step-by-step explanation:

Let the interest rate be same for all the loans and consider it to be R.

<u>First case</u>

Principal 1 = 2000

Time = 12 moths = \frac{12}{12} = 1 year

Rate = R %

So, interest 1 = Principal * Time * Rate

                   = 2000 * 1 * R

                   = 2000R

Now,

Principal 2 = 1000

Time = 12 moths = \frac{12}{12} = 1 year

Rate = R %

So, interest 2 = Principal * Time * Rate

                   = 1000 * 1 * R

                   = 1000R

Total interest to be paid = 2000R + 1000R

                                         = 3000R

<u>Second case</u>

Principal = 3000

Time = 12 moths = \frac{12}{12} = 1 year

Rate = R %

Interest = Principal * Time * Rate

             = 3000 * 1 * R

             = 3000R

We conclude that there would be no savings because the interest to be paid in both the cases are same.

A zoo has 151515 Emperor penguins. The Emperor penguins make up 30\%30%30, percent of all the penguins at the zoo.
Fiesta28 [93]

Answer:

50 total penguins

Step-by-step explanation:

In the following example x = the total number of penguins.

Set it up as follows.

15 over x = 30 over 100

Cross multiply the numbers. (30 times x) and (15 times 100)

This results in 30x = 1500.

Divide both sides by 30 which results in x = 50.

This means that there is a total of 50 penguins.

In the following example x = the number of Emperor penguins.

If you would like to double check this, set up as follows.

x over 50 = 30 over 100

Cross multiply the numbers. (30 times 50) (100 times x)

This results in 100x = 1500.

Divide both sides by 100 which results in x =1 5.

This means that there are 15 Emperor penguins.
