c.12/39
d.4/13

sorry if I am asking so many questions

Answers

Answer 1
Answer: (number\ of\ tickets\ Janne)/(number\ of\ tickets\ Jake)=(12)/(39)=(12:3)/(39:3)=(4)/(13)\n\nAnswer:\boxed{D.\ (4)/(13)}
Answer 2
Answer: jake:Jeanie
39:12
39=3*13
12=3*2*2
so (3*13)/(3*2*2)
we can factor out the 3/3 or 1
so 13/4
jake:Jeanie is 13/4

Which of the following represents exponential growth?y = 2x + 5
y - x = 4
x = 3
y = 5 * 2^(x)

Answers

Answer:

y = 5 × 2^(x)

Step-by-step explanation:

Exponential growth equations are usually in the form y = a × b^(x).

So, y = 5 × 2^(x) is the best fit for that format.

Have a great day!

The exponential growth:

y=a\cdot b^x

Therfore your answer is y=5*2^x

--------------------------------------------------------

y = 2x + 5    it's a linear function in slope-intercept form

y - x = 4 → -x + y = 4   it's a linear function in standard form

x = 3   it's a vertical line

At 1:00 pm the water level in a pool is 13 inches. At 1:30pm the water level is 18 inches. At 2:30pm the water level is 28 inches. What is the constant rate of change?

Answers

From the given question we come to know of certain number of facts and they are:
At 1:00 PM the water level of the pond was = 13 inches
At 1:30 PM the water level of the pond was = 18 inches
At 2:30 PM the water level of the pond was = 28 inches
From the above given facts we can easily find the amount of water changing every half an hour.
Amount of increase in water from 1:00PM to 1:30 PM = (18 - 13) inches
                                                                                       = 5 inches
Amount of increase in water level from 1:30PM to 2:30PM = (28 -18) inches
                                                                                             = 10 inches
From the above two deductions we can come to the conclusion the the constant rate of change in water level is 5 inches for every half an hour.
Per 1/2 an hour it is changes by 5 so the constant rate would be: 5 inches per 1/2 an hour

Lunch A survey showed that 30% of students bring their lunch to school. The survey polled 300 students. How many of the 300 students do not bring their lunch to school?

Answers

The number of students who do not bring lunch will be 210.

What is the percentage?

The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol ‘%’ is used to symbolize it.

Lunch A survey showed that 30% of students bring their lunch to school. The survey polled 300 students. Then the percentage of students who do not bring lunch will be

⇒ 100% - 30%

⇒ 70%

Let x be the number of students who do not bring lunch. Then we have

x = 70% of 300

x = 0.70 × 300

x = 210

The number of students who do not bring lunch will be 210.
