If we calculate the distance between two points, it is equivalent to one side of the rectangle. Using the distance formula:
d = √((x₂ - x₁)² + (y₂-y₁)²)
We compute the distance between the points (-3,2) and (5,4)
d = √((5 + 3)² + (4 - 2)²) = √68
Now, we check the next two points:
d = √((6 - 5)² + (0 - 4)² = √17
Now, we know that the adjacent sides of a rectangle are equal so the perimeter can be calculated using:
P = 2(l₁ + l₂)
P = 2(√68 + √17)
=24.7 units.
Answer:
Step-by-step explanation:
okay so 40 divided by 159 equals .2515 than you are going to add 159 which gives you 159.2515 and than round that to the nearest 100
Answer:
60cm
Step-by-step explanation:
perimeter of a square=4L
192cm=4L
L=48cm
Dilated by ratio 0.25
1 : 0.25 = 48 : 12
New length = 48+12 = 60cm.
Answer:
d. n = 12
Step-by-step explanation:
n/33 = 4/11
cross-multiply:
11n = 132
divide both sides by 11:
n = 12
We are asked to simplify the ratio of 34 laptops out of 116 computers into the simplest form. The greatest common factor is 2. hence, we divide each number by 2. 34 divided by 2 is equal to 17 while 116 divided by to is equal to 58. Hence the answer to this problem is b. 17 <span>laptops : 58 computers. </span>
