To find the area we need to do the things below:
Let:
42 = perimeter of KLMN
h1 = 5
h2 = 6
the perimeter of a parellelogram is equal to 2 (a +b)
let:
a = KL
b = LM
area of a parallelogram = bh
(also known as base x height)
b = LM
h = h1
Find the values of a and b in order to solve for the area of KLMN. Similar triangle means they are proportionality is equal.
P = 2 (a +b)
42 = 2(a+b)
12/2 = a + b
21 = a+b
21 -a = b
note:
hypotenuse / long leg
a / 5 = b/6
(21-a) / 6
a*6 = 5 (21 - a)
6a = 105 - 5a
6a + 5a = 105
11a = 105/11
= 9.55
b = 21 -a -> b = 21 - 9.55
b = 11.45
using the equation of the area of parallelogram:
area = bh
A = 11.45 * 5
A =57.25 square units
*below is an attached figure of the problem
Answer:
2.8 in
Step-by-step explanation:
The volume of any shape is given as the product of base area and height. Therefore, V=Ah
Where A is cross sectional area, h is height
For a triangular, the cross sectional area is given by ½lw where l is length and w is width.
Now v=½lwh
Given that v=4 in³
4=½lwh
8=lwh
Considering the given choices, l can be 2.8 in
The probability of picking a head and a number 4 is 0.25.
<h3>How to calculate the probability?</h3>
Your information is incomplete and the complete information wasn't found. An overview will be given.
A coin has a head and tail and the probability of choosing either is 1/2 or 0.5.
Let the 2 numbers be 1 and 4. The probability of picking either number will be 1/2 or 0.5 as well.
Here, let the probability of picking a head and a number 4 will be:
= 1/2 × 1/2
= 0.5 × 0.5
= 0.25

Your problem is an example of a distance problem, so you muct know the formula to find the distance. To find the distance we simply multiply the rate by the time, or as you'll see more often, d = r t. That means to calculate distance traveled you need rate and time.
Take note, planes are traveling in opposite direction, which means 2000 miles will be the sum of the distances that the two planes have traveled.
D (Plane 1) + D(Plane 2). = 2000
Let t = time in minutes
560t + 500t = 2000
Solve for t. Take it ftom here.
