Choose the answer that validates that the rate of change is constant by showing that the ratios of the two quantities are proportional and equivalent to the unit rate (simplified constant rate of change): NUMBER OF TEXTBOOKS Number of Students Number of Textbooks 7 35 14 70 21 105 28 140
Answers
Given:
The table of values is
Number of Students : 7 14 21 28
Number of Textbooks : 35 70 105 140
To find:
The rate of change and showing that the ratios of the two quantities are proportional and equivalent to the unit rate.
Solution:
The ratio of number of textbooks to number of students are
[tex]\dfrac{35}{7}=5[/tex]
[tex]\dfrac{70}{14}=5[/tex]
[tex]\dfrac{105}{21}=5[/tex]
[tex]\dfrac{140}{28}=5[/tex]
All the ratios of the two quantities are proportional and equivalent to the unit rate.
Let y be the number of textbooks and x be the number of students, then
[tex]\dfrac{y}{x}=k[/tex]
Here, k=5.
[tex]\dfrac{y}{x}=5[/tex]
[tex]y=5x[/tex]
Hence the rate of change is constant that is 5.

Answers
Answer:
Area of rectangular garden = lxb = 10*5
= 50 sq. inch
when area increases by six times
new area = 50*6 = 300 sq inches
now,
let x be increasement in both length and width
(5+x) (10+x) = 300
50 + 5x + 10x + x² = 300
x² + 15x - 250 = 0
x²+ 25x-10x -250 = 0
x(x+25) - 10 (x+25) = 0
( x-10) (x+25) = 0
either x + 25 =0
x = -25 length can be negative
0r x-10 = 0
x = 10
so 10 inches is increase on both side

Answers
Answer:
The correct answer is 1.
Step-by-step explanation:
In order to solve the problem [tex]\frac{3}{9}[/tex] + [tex]\frac{2}{3}[/tex], we need can use two methods.
Method 1: Make the denominators the same.
3/9 + 2/3 =
3/9 + 6/9 =
9/9 =
1
Method 2: Turn both fraction into decimals (by dividing the numerator by the denominator.)
3/9 or 3 ÷ 9 = 0.3 (when rounded to the nearest tenth)
2/3 or 2 ÷ 3 = 0.7 (when rounded to the nearest tenth)
0.3 + 0.7 = 1
Therefore, the answer to this question is 1.
Explanation: First we need to find a common denominator which the easiest would be nine and then multiply those to equal nine and then you will get 3/9+6/9 which is equal to 9/9 which reduces to 1 have a nice day (:

Cell phone Plan A costs $70 per month and comes with a free $500 phone. Cell phone Plan B costs $50 per month but does not come with a phone. If you buy the $500 phone and choose Plan B, how many months is it until your cost is the same as Plan A's?
I got two different answers last time. One said 25 and the other said 11. Are either of them correct?
Answers
Answer:
25 months
Step-by-step explanation:
Plan A : $70 per month
Plan B : $50 per month + $500 as a one time cost.
So for A $70 a month would take 8 months to be at least $500
And for B it in those 8 months it would cost you $900
But we have to keep going up until they are equal
25*70 = 1750
(25*50) = 1250+500=1750
So yes 25 months is correct
A study of a population of 1,500 moths revealed that 15 out of every 75 moths in the population have gray stripes on their wings. Based on the results of this study, how many moths in the population have gray stripes on their wings?
Answers
Answer: 300 moths
Step-by-step explanation:
Since 15 out of every 75 moths in the population have gray stripes on their wings, this means the fraction of moths that have gray stripes on their wings is 15/75 = 1/5.
Therefore, out of 1500 moths, the number of moths in the population that have gray stripes on their wings would be calculated as:
= 1/5 × 1500
= 300 moths
