Hi there!
Answer:
The area of the shaded region is 28 in²
Step-by-step explanation:
You will have to do 3 different steps in order to find the area of the shaded region.
First, you will need to find the total area of the rectangle using the values you have and the area formula for a rectangle, which is : A = Length × Width
"A" is the area, which is what we are looking for
The "Length" is equal here to 8 inches
The "Width" is equal here to 5 inches
A = 8 × 5
A = 40 in²
Now that you have the area of the rectanlge, your second step is to find the area of the triangle using the values you have and the area formula for a triangle, which is : A = (Base × Height) ÷ 2
"A" is the area, which is what we are looking for
The "Base" is equal here to 8 inches
The "Height" is equal here to 3 inches
A = (8 × 3) ÷ 2
A = 24 ÷ 2
A = 12 in²
Now that you have both the area of the rectangle and the area of the triangle, all you have to do for your third and final step is subtract the area of the triangle from the area of the rectangle so that you are left with the area of the shaded region :
Area shaded region = 40 in² - 12 in²
Area shaded region = 28 in²
There you go! I really hope this helped, if there's anything just let me know! :)
Answer:
b = 12
Step-by-step explanation:
The mistake Megan has made is that she has squared the lengths and then added it instead of taking away the squared length's. The method she used was to work out the hypotenuse, so the correct method would be as follows:
a² + b² = c²
→ Substitute in the values
5² + b² = 13²
→ Simplify the equation
25 + b² = 169
→ Minus 25 from both sides to isolate b²
b² = 144
→ Square root both sides to find the value of b
b = 12
|B|(3/3⋅2/3⋅3/3) in.^3 = 2/3 in^.3
|C|(3 1/3⋅2 1/3⋅3 1/3) in.^3=25 25/27 in.^3
|D|(3⋅2⋅3) in.^3=18 in.^3
Answer:
Option B
Step-by-step explanation:
step 1
Find the number of cubes in the prism
step 2
Find the volume of one cube
The volume of one cube is equal to
where
b is the length side of the cube
we have
substitute
step 3
To find out the volume of the prism , multiply the volume of one cube by the number of cubes
so
simplify
Answer:
|B|(3/3⋅2/3⋅3/3) in.^3 = 2/3 in^.3
Step-by-step explanation:
On a coordinate plane, 1,2 and -2,2 would be 3 units apart.
-1
1
0
Undefined
Answer:
slope is 0
Step-by-step explanation:
x= -1 means that the x-intercept is -1
undefined means n/0 , it is a vertical line
for u to get the answer as 0 it is like 0/n
