With these values x = 14.
In order to find this, we must note that LM will be half of KM (since L is the midpoint). Because we know this, we also know that we can multiply LM by 2 and set equal to KM.
2LM = KM
2(2x + 4) = 5x - 6
4x + 8 = 5x - 6
8 = x - 6
14 = x
4/5 as a percent would be 80% because 100 divided by 5 is 20 then multiply by 4 which is 80%. Then for the 1 which is a whole equals 5/5 so it would be 100% which you add to the percent of the 4/5 and it would be 180% total.
Answer:
Step-by-step explanation:
A) You are painting 5 faces, four sides and the bottom, of the pool because you are not painting the top of the pool.
B) You need 104 square meters to paint the pool.
Assuming the pool is a rectangular prism, use the surface area equation:
SA = wl + 2(hl) + 2(hw)
Note: Do not include times 2 for wl because we are only including the bottom of the pool.
l = 8 meters
w = 6 meters
h = 2 meters
SA = (6)(8) + 2((2)(8)) + 2((2)(6))
SA = 104 square meters
C) The paint with cost $624 total. $104 times 6 square meters equals $624

Answer:</h2>
<h2>
Step-by-step explanation:</h2>
We use the concept of inequality to refer to values that are different. To solve this type of problems we need to use the symbols:
In this problem, Megan is making quilts that require 11 feet of cloth each. We also know that she has 50 feet of cloth. So the maximum quilts she can make is:
Writing this using inequalities, she can make:
Since 4.54 is a real number and since quilts need to be represented with whole numbers, we can say that she can make 1, 2, 3, or 4 quilts.
Answer:
a = 242 adult and c = 52 children
Step-by-step explanation:
Solving as a system of equations.
a = adult
c = children
The adult and the children equal 294 people
a + c = 294
adult cost is 2.25 per adult
Total amount of adult is 2.25a because the number of adult are not given.
children cost is 1.75 per children
Total amount children is 1.75c because the number of children are not given
Total receipts $635.50.
a + c = 294 <em>multiply by -1.75</em> -1.75a - 1.75c = - 514.50
2.25a + 1.75c = 635.50 <em>does not change </em>2.25a + 1.75c = 635.50
<em>Add these equations together</em>
-1.75a - 1.75c = - 514.50
<u><em> </em></u><u>2.25a + 1.75c = 635.50 </u>
<em> </em> .50a = 121.00
a = 121.00/.50a
a = 242 adult
a + c = 294
242 + c = 294
c = 294 - 242
c = 52 children
Check: $2.25(242) + $1.75( 52) = $635 .50
$544.50 + $91.00 = $635.50
$635.50 = $635.50
