What are the steps to finding areas?
Trapezoid:
Rectangle:
Circle:
Triangle:

Answers

Answer:

Trapezoid: So basically to find the area of a trapezoid, multiply the sum of the bases (the parallel sides) by the height (the perpendicular distance between the bases), and then divide by 2.

Rectangle: To find the area of a rectangle, multiply the length by the width. The formula is: A = L * W where A is the area, L is the length, W is the width, and * means multiply.

Circle: The area of a circle is pi times the radius squared (A = π r²).

Triangle: To find the area of a triangle, multiply the base by the height, and then divide by 2. The division by 2 comes from the fact that a parallelogram can be divided into 2 triangles.

A rectangular parking lot has a length of 84 feet and a width of 56 feet. Which of the following could be used to find the diagonal distance across the parking lot?
A. 84² – 56² = c²
B. (84 + 56)² = c²
C. 84² + b² = 56²
D. 84² + 56² = c²

Answers

Answer:

The diagonal is approximate is 101 feet

Step-by-step explanation:

Since the parking lot is rectangular, dividing it diagonally makes it two right angle triangles.

l = 84 ft and w = 56 ft

the diagonal becomes the hypothenus of the right angle triangle

so length and width are opposite and adjacent

Then we can now use pythagoras theorem, we will have

l² + w² = d²

84² + 56² = d²

7056 + 3136 = d²

10192 = d²

d² = 10192

d = √10192

d = 100.955

d ≈ 101 ft

triangle 1: m<1 =65o, m>2 =101o

C. triangle 1: m<1 =45o, m>2 =80o

triangle 1: m<1 =59o, m>2 =45o

D. triangle 1: m<1 =71o, m>2 =32o

In a garden, 2/3 of the flowers are roses. Of the roses in the garden, 5/12 are yellow and the rest are red. What fraction of the flowers are red roses?

Answers

7/18 of the flowers are red roses

because 5/12 are yellow, the rest would be red. so 7/12. but total roses are only 2/3 of the whole garden.

tip: when you see "of" in a fraction problem, it means you can multiply them.

so, 7/12 OF 2/3 is just (7/12) * (2/3).
multiplying straight across and simplifying will get you to 7/18!

Answer:  D) 198 square meters

======================================================

Explanation:

Extend the side that's 9.5 meters long out to the left so that you form a trapezoid on top and a rectangle underneath. The side we extended is now 5+9.5 = 14.5 meters long.

Let

A = area of the trapezoid up topB = area of the rectangle underneath

The goal is to find A+B

The trapezoid has the parallel sides of 14.5 and 10 meters. The height of the trapezoid is 28-20 = 8 meters. So we can say

Area of trapezoid = height*(base1+base2)/2

A = h*(b1+b2)/2

A = 8*(14.5+10)/2

A = 98

The rectangle has area of B = length*width = 5*20 = 100 square meters

Therefore,

total area = A+B = 98+100 = 198 square meters.

A polar bear travels across the snow at a rate of 25 miles per hour. Which representation shows the distance a polar bear can travel at this rate?

A. y = x + 25
B. y = 25x
C. y = x - 25
D. y = 1/25x

Answers

Answer: B

Step-by-step explanation:

Y (distance) is 25 multiplied by x

x is how many hours

so if we make x hours,

25x = y

B is the answer because x represents the hours. We know that 25 is how many miles the bear can travel per hour. Therefore, y = 25x

Can you please check over my answer for volume and help me with the surface area?

Answers

Answer:

the surface area of the figure is 622 m ^2

the volume of the figure is 494 m ^3

Step-by-step explanation:

-you find the surface area for the rectangular prism and the triangular prism and add both answers.

- Rectangular prism S.A : 382 ^ 2              382m ^2 + 240m ^2 = 622 m ^2

-  triangular Prism S.A : 240 ^ 2        

-same thing with the volume,find the volume of the rectangular prism and the triangular prism and add those answers to find the total volume of your figure.

- Rectangular Prism  Volume : 380 m^3         380 m ^3 + 114 m ^3 = 494 m ^3

- Triangular Prism  Volume :  114  m ^3

formula for volume of a rectangular prism : V = w * l * h

formula for volume of a triangular prism : V  = A * h

formula for surface area of a triangular prism simplified :

find the area of your base [area of the triangle on your triangular prism and since you have 2 multiply by 2,formula for area of 2 bases: A= 2 (1/2 * b*h) ) ]

next step-

formula for a surface area of a rectangular prism : 2 (w*l + l*h + h*w )

a-area      w- width     l-length    

h-height  s.a -surface area
