Answer:

150%

It is a percentage increase

Step-by-step explanation:

We start by calculating the percentage increase

Mathematically, we have this as;

Percentage increase = (new value - old value)/old value * 100%

New value = new height = 60 inches

old value = old height = 24 inches

Substituting these values, we have ;

(60-24)/24 * 100%

= 36/24 * 100%

= 1.5 * 100% = 150%

It is a percentage increase as we can see growth

Answer:

7/8, 7/10, 7/11, 7/12

Answer:

7/12 , 7/11, 7/8, 7/10

Step-by-step explanation:

Based on her results, if she flipped the coins another 50 times, she should expect to flip heads 20 times. If Jessica flips a coin 100 times and gets 40 times heads and the next time she flips a coin 50 times she should get 20 because, 100 divide 2 is 50 so you would have to divide 40 with 2 and get the answer of 20.

Answer: a= 14 , b= 15, c =15 , d =18 , e= 18.

Step-by-step explanation:

Stratified sample is a sampling technique used to show the participation of each group present in the population..

Person sampled from each group =[tex]\dfrac{Person\ in\ group}{Population}\times sample\ size[/tex]

Total students = 140+150+150+180+180 =800

In sample

Person of Year 7 students = [tex]\dfrac{140}{800}\times80=14[/tex]

Person of Year 8 students = [tex]\dfrac{150}{800}\times80=15[/tex]

Person of Year 9 students = [tex]\dfrac{150}{800}\times80=15[/tex]

Person of Year 10 students = [tex]\dfrac{180}{800}\times80=18[/tex]

Person of Year 11 students = [tex]\dfrac{180}{800}\times80=18[/tex]

Hence, a= 14 , b= 15, c =15 , d =18 , e= 18.

Answer:

6.5 Hours

Step-by-step explanation:

If it takes Ron 12 hours to go 6.8 miles then 8 hours more is only 1.7 miles an hour. It will take him well over 6.5 hours to do 20 miles so 6.5 hours is the closest answer

The time that should be taken for Ron to travel 20 miles in 3.5 hours.

Given that

Ron traveled 6.8 miles in 1.2 hours.

We need to find out the time that should be taken for Ron to travel 20 miles.

So, the time taken should be

[tex]= \frac{20\ miles \times 1.2\ hours}{6.8\ miles}[/tex]

= 3.5 hours

Here we assume that time should be 1.2 hours instead of 12 hours.

Therefore we can conclude that The time that should be taken for Ron to travel 20 miles in 3.5 hours.

Answer:

42 people

Step-by-step explanation:

Step one:

given data

The ratio of girls to boys on the tennis team is 3 to 4.

the combined ratio= 3+4= 7

total boys = 24

Required

the total number of people

Step two:

applying the part to all method, let the total people be x

4/7= 24/x

cross multiply we have

4x= 24*7

4x=168

divide both sides by 4

x=168/4

x= 42

y = 5(2) -9

y = 1

Answer:

(2, -3)

Step-by-step explanation:

The  x-axis is the perpendicular bisector of a segment with an endpoint of (2,3).

A perpendicular bisector is a line which is perpendicular to a segment, dividing the segment into two equal parts. The perpendicular bisector passes through the midpoint of the segment.

Since the x axis bisects a segment with an endpoint of (2,3) perpendicularly, hence a point on the x axis is the midpoint of the segment. The midpoint would have the same x coordinate as the endpoint.

Hence, the midpoint is (2, 0).

Let (x, y) be the other endpoint, then:

(2, 0) is the midpoint of the segment joining (2, 3) and (x, y). we find the value of x and y using:

(2 + x) / 2 = 2;  and (3 + y) / 2 = 0

2 + x = 4;  and 3 + y = 0

x = 4 - 2 ;    and y = 0 - 3

x = 2; and y = -3

Hence the other endpoint is at (2, -3)

Because the x-axis is the perpendicular bisector of a segment with an endpoint of (2, 3), we will see that the other endpoint must be at (2, -3).

First, we know that the x-axis is perpendicular to our segment, so our segment must be a vertical segment. This means that there can't be a variation in the x-values between the endpoints.

So, if one endpoint is (2, 3), then the other must be (2, y).

To find the value of y we use the fact that the x-axis is also a bisector, so it divides the segment in two equal parts, then we must have y = -3

In this way, we can conclude that the other endpoint is (2, -3)

Answer:

x = 5,3

Step-by-step explanation:

Perimeter is the sum of the two lengths plus the sum of the two widths.

Divide the perimeter in half and that is the sum of one length and one width.

27/2  = 13.5

The ratio is 2:1, add the ratio: 2 +1 = 3

Divide the sum by 3:

13.5/3 = 1.5

Multiply that the each portion of the ratio:

4.5 x 2 = 9

4.5 x 1 = 4.5

The length is 9 inches

The width is 4.5 inches
