Answer:
The answer to your question is below
Step-by-step explanation:
Formula
Triangle's Area = 1/2 bh/2
Trapezoid's area = 1/2 (b1 + b2)h
Parallelogram's area = bh
Rectangle's area = bh
Considering the formulas, we can conclude that:
a) The first choice is true, both formulas have 1/2 in.
b) The second choice is also true, both equations are the same
c) The third choice is incorrect
d) This choice is correct, the bases are added,
e) This choice is incorrect, the sides are not added.
Answer:
121 smokers
Step-by-step explanation:
This can be calculated as a simple rule of 3.
In these problems, the first step is identifying the measures in the problem. Then, we must identify whether their relation is direct or inverse.
When it is direct, as one measure increases, the other will increase too.
When it is inverse, as one measure increases, the other will decrease.
In this problem, the measures are the number of people over 12 that smoke, and the total number of people over 12. Their relation is direct, because as the number of people increases, the number of smokers will increase too.
So we must solve the following rule of three:
22 smokers - 100 people
x smokers - 550 people
x = 550*22/100
x = 22*5.5
x = 121 smokers.
So, in a group off 550 people over the age of 12, there are 121 expected smokers.
Answer: 518.94 square centimeters
Explanation:
The surface area of the cube is given by
Surface Area = 6*(edge)²
Since the edge of the cube in this problem is its length, the egde is 9.3 cm. Hence, the surface area of the cube is calculated as
Surface Area = 6*(edge)²
= 6*(9.3 cm)²
Surface Area = 518.94 square centimeters
