I'm doing this stuff right now your answer is To find the complementary angle,you subtract 90 by the first given complement angle. To find the supplementary angle,, you subtract 180 by the first given supplement angle.

The complement is 90 - a

The suplement is 180 -a

where a is the measure of the angle

Step 1

<u>Find the slope of the line PQ</u>

we know that

the formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have

$P(-3,-3)\\Q(3,-1)$

substitute the values

$m=\frac{-1+3}{3+3}$

$m=\frac{2}{6}$

$m=\frac{1}{3}$

Step 2

Find the equation of the line that passes through point R ans is parallel to line PQ

we know that

If two lines are parallel, then their slopes are the same

The equation of the line into point-slope form is equal to

$y-y1=m(x-x1)$

we have

$m=\frac{1}{3}$

$(x1,y1)=R(1,1)$

substitute the values

$y-1=\frac{1}{3}(x-1)$

Step 3

we know that

The point on the y-axis that is on the line $y-1=\frac{1}{3}(x-1)$ is equal to the y-intercept of the line

The y-intercept is the value of y when the value of x is equal to zero

For $x=0$ find the value of y in the linear equation

$y-1=\frac{1}{3}(0-1)$

$y-1=-\frac{1}{3}$

$y=1-\frac{1}{3}$

$y=\frac{2}{3}$

The point that is on the y-axis is $(0,\frac{2}{3})$

therefore

<u>the answer is the option A</u>

$(0,\frac{2}{3})$

Round to the nearest whole number to estimate the sum of 23.19 and 13.7. Then give the exact sum.

Olegator [25]

If you round 23.19 to the nearest whole number you get 23 and if you round 13.7 you get 13. 13+23 is 33. The real numbers are 23.19 and 13.7, add them together and you get 36.89. The exact sum is 36.89 (:

2. Susan wants to use blue, yellow, green, and pink paint to decorate her house. She needs 3 times as much blue paint as yellow

Alex

Answer:

B = Blue

Y = Yellow

G = Green

P = Pink

The info that we have is:

3*B = Y

(1/2)Y = G

P = (3 + 1/4) gal

P = G + 3/4 gal.

So we have 4 equations. The first step is replacing the third equation into the fourth equation, and get:

G + 3/4 gal = (3 + 1/4) gal

G = (3 + 1/4) gal - 3/4 gal = (2 + 2/4) gal

Now we can replace this into the second equation ((1/2)*Y = G) to find the value of Y.

(1/2)Y = (2 + 2/4) gal

Y = 2*(2 + 2/4) gal = (4 + 1)gal = 5 gal.

Now we can replace this into the first equation and get:

3*B = 5gal

B = 5/3 gal = (1 + 2/3)gal

So the total amount of paint used is:

T = P + G + Y + B = (3 + 1/4) gal + (2 + 2/4) gal + 5gal + (1 + 2/3)gal

T = (11 + 3/4 + 2/3)gal

T = (11 + 9/12 + 8/12)gal = (11 + 17/12)gal = (11 + 1 + 5/12)gal = (12 + 5/12) gal.
