Answer: Trapezoid
A trapezoid is a quadrilateral with exactly one pair of parallel sides. The other two opposite sides are not parallel. In order to have a parallelogram, we need two pairs of opposite parallel sides (not just one pair). Since a trapezoid is not a parallelogram, this means this is a counterexample to the original statement.
Answer:
It will take 2 hours, 13 minutes and 20 seconds for both pipes to fill the pool.
Step-by-step explanation:
Given that an inlet pipe can fill an empty swimming pool in 5hours, and another inlet pipe can fill the pool in 4hours, to determine how long it will take both pipes to fill the pool, the following calculation must be performed:
1/5 + 1/4 = X
0.20 + 0.25 = X
0.45 = X
9/20 = X
9 = 60
2 = X
120/9 = X
13,333 = X
Therefore, it will take 2 hours, 13 minutes and 20 seconds for both pipes to fill the pool.
Answer:
The product of 1/6 × 3/2 will be greater than 1/6.
Step-by-step explanation:
Let's start by converting the fraction 3/2.
We are given a number greater than 1. Since you are multiplying 1/6 by a number greater than 1, the answer is an increased value compared to the original number.
We can also prove this the mathematical way:
1/4 > 1/6, or 0.25 > 0.1(6)
Tan (0) is equal to 0
Sin (0) = 0
Cos (0) = 1
Tan = Sin/Cos
That means that Tan (0) = 0/1 or 0
