Answer:
y = 8
x = 8√5
z = 4√5
Step-by-step explanation:
Using the formula (which is a geometric mean):
a y
---- = -----
x a
Where a is the altitude (y), x is a projection (16), and y is the other projection (4):
y 4
---- = -----
16 y
Cross multiply:
y² = 16 (4)
y² = 64
√y² = √64
y = 8
To find x and z, use the Pythagorean Theorem:
16² + y² = x²
256 + 8² = x²
256 + 64 = x²
320 = x²
√320 = √x²
√64√5 = √x²
8√5 = x
x = 8√5
4² + y² = z²
16 + 64 = z²
80 = z²
√80 = √z²
√16√5 = √z²
4√5 = z
z = 4√5
First, figure out how much Aniyah started with. Add. Show your work.
Then, write out the fraction (amount spent) / (amount Aniyah began with).
Last, multiply your result by 100%, and then round off the resulting percentage to the nearest integer number.
Answer:
<h2>7</h2>
Step-by-step explanation:
Let the point A(a, b) and the line x = k. The distance between the point A and the line k is equal |k - a|.
We have A(-3, 4) and x = 4. Substitute:
d = |4 - (-3)| = |4 + 3| = |7| = 7
If you would like to know what is 25 percent of 225, you can calculate this using the following steps:
25 percent of 225 = 25% * 225 = 25/100 * 225 = 56.25
Result: 25 percent of 225 is 56.25.
