Answer:
X = 25
Step-by-step explanation:
To solve this question, we'll first of all find determine the side length of the triangle from the perimeter.
Perimeter of an equilaterial triangle = 3 * s
S = side length
Perimeter = 150cm
150 = 3s
S = 150 / 3
S = 50cm
The side lengths are 50cm each since they are all equal.
To find x,
We have to divide the triangle equally into two different part.
Check the first attachment for better illustration on how the equilaterial triangle is.
Check the second attachment for better illustration on the triangle when its divided into a right angle triangle.
From the right angle triangle, we can use pythagorean theorem to solve for x
a² = b² + c²
a = 50cm
b = 25cm
c = x√(3)
50² = [x√(3)]² + 25²
2500 = x² * 3 + 625
2500 - 625 = 3x²
1875 = 3x²
X² = 1875 / 3
X² = 625
X = √(625)
X = 25
Answer:
To be honest dont know
Step-by-step explanation:
2+2=Fish
Step-by-step explanation:
x varies inversely as y. This means that x is equal to the inverse of y which can be translated as x = 1/y but the problem said that x is <u>n</u><u>o</u><u>t</u><u> </u><u>e</u><u>x</u><u>a</u><u>c</u><u>t</u><u>l</u><u>y</u><u> </u><u>e</u><u>q</u><u>u</u><u>a</u><u>l</u><u> </u>to the inverse of y. Therefore, we need to introduce a factor k. Factor k will represent the word "varies" in the problem.
To illustrate:
Since we don't have the value of k, we have to solve for it by using the first values of x and y which was given as x=2 and y=20.
Now that we have the value of k, we can now solve for the value of x when y=5.
Therefore, when y is 5, the value of x is 8.
Answer:
Step-by-step explanation:
Four consecutive counting numbers would look like this
x
x + 1
x + 2
x + 3
Do you see that these numbers are 1 larger than the one before it. So if x is 20 the numbers would be 20 21 22 23
Now take the 4 general numbers and add them
x + x + 1 + x+2 + x + 3
4x + 6
Two will go into 4x to give 4x/2 = 2x
Two will go into 6 to give 6/2 = 3
Always happens. There are no exceptions. Try x = 20 again
20 + 21 + 22 + 23 = 86
Can this number be divided by 2? Yes it can 86/2 = 43
The Answer is:
$14.16 / 3 = $4.72
$4.72 x 14 = $66.08
