To determine the perimeter of the trapezoid, we just have to determine the distance between the pair of points which can be calculated through the equation,
d = √(x₂ - x₁)² + (y₂ - y₁)²
Substituting,
(1,4) and (-2,0) d = √(1 - -2)² + (4 - 0)² = 5
(-2,0) and (7,0) d= √(-2 - 7)² + (0 - 0)² = 9
(7,0) and (3,4) d = √(7 - 3)² + (0 - 4)² = 5.66
(3,4) and (1,4) d = √(3 - 1)² + (0 - 0)² = 2
The perimeter is the sum of the distances. Thus, the answer is 21.66.
1 = 100%
21 ÷ 50 = 0.42
0.42 = 42%
Add:
100 + 42 = 142
Answer = 142%
Hope this helped☺☺
Answer:
Step-by-step explanation: The most important step to do is to simplify the equations down. We do this by finding common variables.
Common Variables are pairs such as 12x and 32x, and not 12x and 32y or 12 and 32.
1.
2.
3.
4. cannot be simplified any further.
5. cannot be simplified any further.
6.
7.
8. cannot be simplified any further.
9. cannot be simplified any further.
Now, we start to match the equations.
Equation 1 is the same as Equation 5
Equation 2 is the same as Equation 9
Equation 3 is the same as Equation 4
Equation 6 is the same as none of them.
Equation 7 is the same as Equation 8.
And there you are have it!
Well to find the area you have to multiply 3.14 by your radius. Then you square it.
Answer:
Use cross product to determine if the two ratios form a proportion. Here we can see that 2/16 and 5/40 are proportions since their cross products are equal. Percent means hundredths or per hundred and is written with the symbol, %. Percent is a ratio were we compare numbers to 100 which means that 1% is 1/100.
