If you want to find the decimal value of a square root, you can use the 2 closest perfect squares to them.
Example
Approximate the value of sqrt20
Pick the 2 closest perfect squares, one before and one after 20:
16 and 25.
So, the square root of 20 has to be between 4 and 5.
Since 20 is closer to 16 than it is to 25,
We can estimate the decimal value of sqrt20 to be around 4.4
Answer:
B
Step-by-step explanation:
|−0.05| = 0.05
|−0.005| = 0.005
0.05 > 0.005
|−0.05| > |−0.005|.
Answer:
Choice C
Step-by-step explanation:
4x+80=180 degrees
summation of all angles in a triangle is 180°
Answer:
x=1, y=-1
Step-by-step explanation:
Given the equation:
where x and y are the blank boxes.
We want to find
A positive value of x
A negative value of y
That makes the equation true.
If x=1, y=-1
This can be confirmed using addition law of indices()
In general, any pair of a number and its negative value will satisfy the equality.
Step-by-step explanation:
174325 rounded to the nearest ten thousand is 170,000
