find the values of x y and z
9514 1404 393
Answer:
x = 18√2y = 18√3z = 36Step-by-step explanation:
These "special" right triangles have side length ratios that it is useful to remember.
45°-45°-90° triangle
Sides have the ratios 1 : 1 : √2. That is, x is √2 times as long as the side length shown as 18.
x = 18√2
30°-60°-90° triangle
Shortest to longest, sides have the ratios ...
1 : √3 : 2
That is, y is √3 times the length of the side marked 18, and z is 2 times the length of the side marked 18.
y = 18√3
z = 2·18 = 36

A rectangle is 12 inches long and 2 inches wide. Find its area. A 22 square inches 14 square inches 24 square inches 26 square inches
Area of given rectangle = 24 square inches.
The correct option is C.
What is rectangle?A rectangle is cyclic: all corners lie on a single circle. ; It is equiangular: all its corner angles are equal (each of 90 degrees).
Given,
Length of rectangle = 12 inches
Width of rectangle = 2 inches
Area of rectangle = length × width
= 12 × 2
Area of rectangle = 24 square inches.
Hence, 24 square inches is the area of rectangle.

Find the value of x
12
5
X
Answer:
x = 13
Step-by-step explanation:
Note that the side length x is opposite of the right angle, which means that it is the hypotenuse, which will usually be denoted as c.
Set the equation:
a² + b² = c²
let:
a = 5
b = 12
c = x
Plug in the corresponding numbers (& x) to the corresponding variables:
(5)² + (12)² = (x)²
Simplify. First, solve for the power, and then add:
x² = (5²) + (12²)
x² = (5 * 5) + (12 * 12)
x² = 25 + 144
x² = 169
Next, root both sides of the equation:
√x² = √169
x = √169 = √(13 * 13) = 13
x = 13

Note the rules, and it should be easier:
30-60-90° = 1 , √3 , 2
45-45-90° = 1 , 1 , √2
Any other measurements use the equation: a² + b² = c²

Ebony is x years old.
Her brother is 4 years older.
Her Mum is 3 times her age.
Write an expression for the age of:
Her mum
Her brother
Ebony's brother is x + 4 years old.
Ebony's mum is 3x years old.
Explanation:Since Ebony is x years old, and her brother is 4 years older than her, the expression is x + 4, as her brother is +4 years older.
Ebony's mum is 3 times Ebony's age, which is x. 3 times x is shortened into 3x.

Micah has 15 games. Micah has three more games than kelly. Kelly has K number of games. Move values into the boxes to create an equation to represent this senerio
Answer:
Equation = K + 3 = 15
K = 12 games
Step-by-step explanation:
According to the scenario, calculation of the given data are as follows,
Micah games = 15
Let, Kelly games = K
As Micah has three more games than Kelly, then
K + 3 = 15
This equation shows the scenario.
We can find the number of games Kelly has by using this equation,
K+3 = 15
K = 15 - 3
K = 12
Hence, Kelly has 12 games.

Answer:
I think the question is supposed to be What is 25% of 24? Or you are missing a component of the question
Step-by-step explanation:
You could multiply .25 times 24 to get the answer because changing 25% to a number you can use in an equation means adding a decimal place and moving two places to the left.
.25 x 24= 6
6 is 25% of 24

Find the perimeter of the following shape (show all work and box your final answer):
=========================================
Work Shown:
To find the perimeter, we add up all the exterior side lengths.
P = perimeter
P = (side1) + (side2) + (side 3)
P = (2y-3x-3) + (12+5x+7y) + (9x-3y+2)
P = (-3x+5x+9x) + (2y+7y-3y) + (-3+12+2)
P = 11x + 6y + 11
