Marta_Voda [28]

Answer:

Increase?

Step-by-step explanation:

Because think about it let's use 1/2 as an example.

1/2 equals .5 now lets add 2 to both the numerator and denominator

3/4 is the result and it also equals .75 which is larger than .5 so that's why the answer is increase.

Alan solved the proportion StartFraction x over 200 EndFraction = StartFraction 8 over 25 EndFraction as shown. StartFraction x
bulgar [2K]

Answer:

Step-by-step explanation:

The proportion that Alan solved was

x/200 = 8/25

His working as shown was

(8)(x) = (25) (200)

8x = 5000

He divided both sides of the equation by 8. It became

8x/8 = 5000/8

x = 625

The correct steps are

25x = 200 × 8 = 1600

Dividing both sides of the equation by 25, it becomes

x = 1600/25

x = 64

Alan's error were:

1) He got the wrong product when he multiplied 25 by 200.

2)He got the wrong quotient when he divided 5,000 by 8.

The number of mice tripled each year for the past 4 years in the small rural town. Which of the following characteristics best d
saul85 [17]

Answer:

The graph is a curved line that increases.

Step-by-step explanation:

If the mice triple in population every year then the population is increasing an at exponential rate by multiplying the previous mouse count by 3. I have included a image of a graph that would represent this.

Thus the graph is a curved line that increases, it is not a v shape because the population will constantly increase by 3 times each year, it is not a straight line because the mice population is not increasing in a linear fashion and the population is not U shaped as the population will not decrease as long as the mice population triples every year.

Hope this helps!
