B.90 if angles are supplementary that means they add up to 180 degrees and 90 plus 90 is 180

Answer:

B. 90

Step-by-step explanation:

Since the two angles are supplementary, this means they both are on a flat line (180 degrees)

Since both A and B add up to 180, we take that number and subtract A (90) to get our answer: 90 degrees

Data Set #1

Harman [31]

Answer:

The data table is attached below.

Step-by-step explanation:

The average of a set of data is the value that is a representative of the entire data set.

The formula to compute averages is:

$\bar x=\frac{1}{n}\sum\limits^{n}_{i=1}{x_{i}}$

Compute the average for drop 1 as follows:

$\bar x_{1}=\frac{1}{3}\times[10+11+9]=10$

Compute the average for drop 2 as follows:

$\bar x_{2}=\frac{1}{3}\times[29+31+30]=30$

Compute the average for drop 3 as follows:

$\bar x_{3}=\frac{1}{3}\times[59+58+61]=59.33$

Compute the average for drop 4 as follows:

$\bar x_{4}=\frac{1}{3}\times[102+100+98]=100$

Compute the average for drop 5 as follows:

$\bar x_{5}=\frac{1}{3}\times[122+125+127]=124.67$

The data table is attached below.

(2x2 − 5x)(4x2 − 12x + 10) multiply

frez [133]

Is this 2x to the power of 2?
if it is then this is easy
list it out (just to show you how its solved)
2x^2*4x^2
2x^2*(-12x)
2x^2*10
then list the other one
-5x*4x2
-5x*(-12x)
-5x*10
so the whole answer is
8x^4+(-24x^3)+(-20x^3)+20x^2+60x^2+(-50x)
