How do you find the area and perimeter of a trapezoid?

Answers

The area of a trapezoid, A, equals h, the height of the trapezoid, times the length of base one plus the length of base two divided by two.
The perimeter of a trapezoid, P, equals the measure of base one plus the measure of base two plus the measure of leg one plus the measure of leg two
That is as simple as i can make it lol. i hope it helps some

Answer:

Area of a trapezoid = [tex]\frac{b_{1} +b_{2} }{2} h[/tex]

Perimeter of a trapezoid = All of the sides added together

In this case:

Area: 32.5 m²

Perimeter: 26 m

Step-by-step explanation:

The area of a trapezoid is base 1 + base 2 divided by 2, and then multiplied by the height.

The perimeter of all shapes is all of the sides added together.

Hope it helps!

What is the distance between the points (12, 6) and (−8, 6) on a coordinate plane?

Answers

Distance between two points calculator, formula, work with steps, step by step ... Find the distance between two given points on a line? ... (8, 2) and (6, 1), 2.2361 ... (-12, 1) and (12, -1), 24.0832

Answer:

The distance is 20 units

Step-by-step explanation:

Both points are on the same y position but different x positions. This means that to find the distance between the points you have to find the distance between -8 and 12. the distance from 12 to 0 is 12 and from 0 to -8 is 8. If you add those 2 distances together you get 20 units.

4) Students surveyed boys and girls separately to determine which sport they enjoyed watching the most. After completing the boy survey, it was determined that for every 2 boys who enjoyed baseball, 5 boys enjoyed basketball. The girl survey had a ratio of the number of girls who enjoyed baseball to the number of girls who enjoyed basketball of 6:1. If the same number of boys and girls were surveyed and 84 boys enjoyed baseball, how many girls enjoy each sport? Use a double tape diagram to show your work.

Answers

Answer:

I used a little bit of the question  i am on Right Now but the answer is in there somewhere

Step-by-step explanation:

ratio for boys:     3 soccer/5 basketball

ratio for girls:      7 soccer/1 basketball   (I think you have a typo when you say "...number of boys who enjoyed basketball

of 7:1" because boys and girls were surveyed separately.)

that said...

90 boys enjoy soccer

3*30/5*30=90 boys enjoy soccer/150 boys enjoy basketball

90+150=240 boys and therefore 240 girls

7/1 is the ratio for girls

7+1=8, 240/8=30

7*30/1*30=210 girls enjoy soccer/30 girls enjoy basketball  (210+30=240)

Belle made a scale drawing of a mural where 2 inches of the drawing represents 3 feet on the actual mural (scale 2 in. = 3 ft.). In real life, the mural is 6 feet tall and 18 feet wide. What is the area of her drawing in square inches?

Answers

Answer:

Very sorry if this is wrong but, I think the answer would be 48 inches.

Step-by-step explanation:

If every 3ft. = 2in. then I believe you would first divide the length and width by 3. So 6 divided by 3 is 2 and 18 divided by 3 is 6. Then you would multiply 2 and 6 by 2 since every 3ft = 2in.

Reason being is because
(2.4r+1.8r)+(0.8+1.3)
This is what you use because r represents oranges so once you put 2.4r and 1.8r they are like terms so you can add them and r will stay the same and 0.8 and 1.3 will be added and no variable will appear when you add them.

A right triangle has side lengths of a, b, and c units. The longest side has a length of c units. Complete each equation to show three relations among a, b, and c.


c2=


a2=


b2=

Answers

The three relations among a, b and c are:

c² = a² + b²a² = c² - b²b² = c² - a²

We need to show the relationship between the right triangle with side lengths a, b and c units where c is the longest side through Pythagoras' theorem

What is Pythagoras' theorem?

Pytrhagoras' theorem states that in any right angled triangle, the sum of the squares of the other two sides equal the square of the third side called the hypotenuse. This hypotenuse is also the longest side of the triangle.

With right triangle with sides a, b and c where c is the hypotenuse side,

i. The value of c²

Pythagoras' theorem is given mathematically as

c² = a² + b²

ii. The value of a²

The other relation is gotten by making a² subject of the formula.

So, a² = c² - b²

iii. The value of b²

The last relation is gotten by making b² subject of the formula.

So, b² = c² - a²

So, the three relations among a, b and c are:

c² = a² + b²a² = c² - b²b² = c² - a²
