Answer:
10
Step-by-step explanation:
A= L²
50 = L² (do opposite operation to find L)
L = 7.07
x²= L²+ L²
x²= 7.07² + 7.07²
x² = 100 ( do opposite operation to make x the subject)
x = 10
Note: opposite operation of square is square root
Answer:
3/5
Step-by-step explanation:
We want to find 3/4 of 4/5.
The keyword <em>of</em> tells us that we need to multiply. Therefore:

Multiply:

So, 3/4 of 4/5 is 3/5.
We can confirm this by converting them to decimals.
4/5 is 0.8.
3/4 is 0.75.
0.75 or 75% of 0.8 is indeed 3/5 or 0.6.
An isosceles triangle has two equal side lengths and the other side length is different. Therefore, possible measures of the other two sides are either
22 cm and 27 cm, or 22 cm and 24.5 cm.
For the same amount set up two equations set equal to each other.
$70h + 130 = 80h + $40
Subtract 80h from both sides
-10h + 130 = 40
subtract 130 from both sides
-10h = -90 divide both sides by -10
h = 9 hours
CHECK
70(9) + 130 = $760
80(9) + 40 = $760
Answer:
D. The range of the function is all real numbers greater than or equal to 0.
Step-by-step explanation:
The graph of the function
is shown in attached diagram.
1. The domain of the function is the set of all possible values for input (for x). Hence, the domain of this function is
![x\in (-\infty,0]](https://tex.z-dn.net/?f=x%5Cin%20%28-%5Cinfty%2C0%5D)
2. The range of the function is the set of all possible values for output (for y), so the range of this function is

As you can see, only option D is true - The range of the function is all real numbers greater than or equal to 0.
