Answer:
Then the total area is 116 cm^2 which agrees with answer D
Step-by-step explanation:
Notice we need to calculate the area of two rectangles (one larger at the bottom and a smaller one on top)
The Area of a rectangle is the product: base x height
In our case :
Area of Big rectangle = 12 cm x 7 cm = 84 cm^2
Area of smaller rectangle = 8 cm x 4 cm = 32 cm^2
Then the total area is: 84 cm^2 + 32 cm^2 = 116 cm^2
Answer: 2.5
Step-by-step explanation:

Answer:
x2 - 4x - 5 factored form is (x - 5)(x + 1)
As given r = r(max)/2
k= 50
r(max) = 0.5
By substituting the values,
r= 0.5/2 = 0.25
You have to use following equation to get a value of N
r = r(max) ( 1- N/K)
N/k = 1 - r/r(max)
N/K = 1 - 0.5 = 0.5
N= 50 × 0.5 = 25
Answer:
x = 20
Step-by-step explanation:
Use Pythagorean Theorem to solve for x:
a^2 + b^2 = c^2
Plug in given values if a = 12, b = 16, and c = x (x is hypotenuse)
12^2 + 16^2 = x^2
(12*12) + (16*16) = x^2
144 + 256 = x^2
400 = x^2
Take square root of both sides to solve for x
sqrt(400) = sqrt(x^2)
20 = x or x = 20
