A triangles area is essentially half of a square. In my math class, we would multiply the main base, and the height and then proceed to break it in half. For example;

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!

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

We could solve problems like these by plugging in values

Let’s start with A

y = 94x

Let’s use 5, 15, 25 from the table

94(5) = 470
94(15) = 1410
94(25) = 2350

Next, B

y = 5x

5(5) = 25

This is wrong

Next, C

y = x + 470

Let’s try 5

475 = 5 + 470

Close, but wrong

Next, D

10 = 5 + 5

This is wrong, so the answer is A.
the answer is y=94x. pls give brainliest

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
