Answer:
48
Step-by-step explanation:
21 white tiles = 63 cm2
total number is 144
144-63 = 81
81/3 = 27
so 27 black tiles
21+27 = 48 total.
Answer:
Step-by-step explanation:
To start of u have to subtract 150 with 180 which is 180 (cuz its a straight line and E to get angle S
Now that we know that 180-150= 30
We add S and R then subtract by 180
so 80+ 30= 110
then we said subtract 180
180-110= 70
Now we know that angle Q is 7-
Then the bottom is RS & SE (NOT REALLY SURE)
It is a Remote Interior Angle
IF RIGHT PLZ GIVE BRAINLIEST
THANK U
HAVE A GREAT DAY AND BE SAFE :)

Given:
The equations of parabolas in the options.
To find:
The steepest parabola.
Solution:
We know that, if a parabola is defined as
Then, the greater absolute value of n, the steeper the parabola.
It can be written as
where 
, the smaller absolute value of p, the steeper the parabola.
Now, find the value of |p| for eac equation
For option A, 
For option B, 
For option C, 
For option D, 
Since, the equation is option A has smallest value of |p|, therefore, the equation 
represents the steepest parabola.
Hence, the correct option is A.
1: 7
2: Yes, 20 because it’s isolated from the rest of the points
(I don’t know the other ones, sorryyyyy)
Answer:
±6
Step-by-step explanation:
Given the mathematical expression;
√36 < √42 < √49
But, √36 = 6 * 6 = 6²
√49 = 7 * 7 = 7²
Simplifying further, we would substitute the new values respectively;
±[6] < √42 < ±[7]
Therefore, evaluating √36 is equal to ±6.
