The sum of present ages of John and his father is 58 years. If John is 24 years younger than his father, then find the present age of John’s father.

Answers

Answer:

father is 41

Step-by-step explanation:

J = johns age

f = fathers age

j+f = 58

j = f-24

Substitute the second equation into the first

f-24 +f = 58

2f -24= 58

Add 24 to each side

2f = 58+24

2f =82

f = 82/2

f = 41

What are the coordinates of the vertices of a rectangle with an perimeter of 12 units and an area of 5 sq. units.

Answers

Answer: The perimeter of the rectangle is: P = 2( w + L) = 2 ( 8+5) = 26 units

The area of the rectangle is A = L w, A = 8 x 5 = 40 units to the 2nd power

Step-by-step explanation:

In order to solve this problem you need to find the distances between the vertices. By inspection the points (5,3) and (5,-2) form one the of the rectangle w = √ ( 5-5)2 + ( -2-3)2 = 5

The length can be obtained by finding distance between the points (5,3) and ( -3,3),

L = √(3-3)2+(-3-5)2 = 8

= 26 units

The perimeter of the rectangle is: P = 2( w + L) = 2 ( 8+5) = 26 units

The rectangle is the quadrilateral with 4 right angles. It could also be defined as, an equiangular quadrilateral, since equiangular means that the all of this angles are = (360°/4 = 90°); and the parallelogram containing a right angle. A rectangle with 4 sides of equal length is a square. The term oblong is occasionally used to refer to a non square rectangle.

The area of rectangle is A = L w, A = 8 x 5 = 40 units to the 2nd power

In order to solve this question you want to find the distances between the vertices. By inspection the points (5,3) and (5,-2) form 1 the of the rectangle w = √ ( 5-5)2 + ( -2-3)2 = 5

The length can be obtained by finding distance between the points (5,3) and ( -3,3),

L = √(3-3)2+(-3-5)2 = 8

The perimeter of rectangle is: P = 2( w + L) = 2 ( 8+5) = 26 units

You work on a problem calculating either area or volume. Your answer is 210 ft3. Did you work on an area or volume problem?

Answers

Answer:

You work on finding volume.

Step-by-step explanation:

Area is squared so it would be something like 210 ft. squared or 210 ft.^2. But since this is area, and it is cubed, it is 210 ft. ^3. You worked on volume.

The measure of the variation of the data is 2.2 hours.

How to calculate the mean average deviation?

The dot plot shows the weekly biking times (in hours). To describe the center, the most appropriate measure is the median, since the distribution appears to be roughly symmetric.

To find the median, we arrange the data in order from smallest to largest:

2, 4, 4, 5, 6, 7, 8, 8, 9, 10

There are 10 data points, so the median is the average of the fifth and sixth values:

median = (5 + 6) / 2 = 5.5

So, the measure of the center of the data is 5.5 hours.

To describe the variation, the most appropriate measure is the mean absolute deviation (MAD), which measures the average distance of each data point from the median.

To calculate the MAD, we first find the deviations of each data point from the median:

|2 - 5.5| = 3.5

|4 - 5.5| = 1.5

|5 - 5.5| = 0.5

|6 - 5.5| = 0.5

|7 - 5.5| = 1.5

|8 - 5.5| = 2.5

|9 - 5.5| = 3.5

|10 - 5.5| = 4.5

Next, we find the average of these deviations:

MAD = (3.5 + 1.5 + 1.5 + 0.5 + 0.5 + 1.5 + 2.5 + 2.5 + 3.5 + 4.5) / 10

MAD = 2.2

So, the measure of the variation of the data is 2.2 hours (rounded to the nearest tenth).

Answer:

75 in

Step-by-step explanation:

Answer:

I think the actual length would be 75 inches. ( i'm not totally sure though C: )

Step-by-step explanation:

So, since the scale factor is 1 : 12, the model is 1/12 of the actual. So, multiply:

6.25 * 12 = 75

So, the actual length would be 75 inches.

To check:

75/6.25 = 12!
