2. C) 189 ft^2
1. Find the perimeter and area of a rectangle with a length of 3.2 m and a width of 1.5 m.
The perimeter of a rectangle is simply twice the sum of it's length and width, so
2(3.2m + 1.5 m) = 2*4.7 = 9.4 m
The area of a rectangle is the product of its length and width, so
3.2 m * 1.5 m = 4.8 m^2
Of the available choices, D matches with p=9.4 m; A= 4.8 m^2
2. Find the area of a triangle with a base of 27 feet and a height of 14 feet.
The area of a triangle is 1/2 base times height, so
0.5 * 27 ft * 14 ft = 189 ft^2
Of the available choices, C matches with 189 ft^2</span>
Answer:
The statement is true.
Step-by-step explanation:
If a linear system has more unknowns than equations, then the system can-not have a unique solution. This is true.
When more unknowns are there than equations, then the system of polynomial equations is said to be under determined.
This means that if any solutions exist, it will not be unique.
Answer:
5/16
Step-by-step explanation:
P(tails) = 1/2
P(>3) = 5/8
P(tails AND >3) = 1/2 × 5/8 = 5/16
