Answer:

x = 12

m(QS) = 52°

m(PD) = 152°

Step-by-step explanation:

Recall: Angle formed by two secants outside a circle = ½(the difference of the intercepted arcs)

Thus:

m<R = ½[m(PD) - m(QS)]

50° = ½[(12x + 8) - (4x + 4)] => substitution

Solve for x

Multiply both sides by 2

2*50 = (12x + 8) - (4x + 4)

100 = (12x + 8) - (4x + 4)

100 = 12x + 8 - 4x - 4 (distributive property)

Add like terms

100 = 8x + 4

100 - 4 = 8x

96 = 8x

96/8 = x

12 = x

x = 12

✔️m(QS) = 4x + 4 = 4(12) + 4 = 52°

✔️m(PD) = 12x + 8 = 12(12) + 8 = 152°

One pipe fills a barrel in 1 hour while another pipe can fill the same barrel in 2 hours. How many minutes will it take to fill
givi [52]

It will take 2/3 hour or 40 minutes to fill the tank if both pipes are used.

Let pi be pipe 1 and pi2 be pipe 2

pi = 1 / 1

pi2 = 1 / 2

together = 1/1 + 1/2 ;

3/2 time ; 2/3 hour.

It will take 2/3 hour or 40 minutes to fill the tank if both pipes are used.

What is the equation of the line in slope intercept form? ILL MARK BRANLIEST ANSWER
lianna [129]

two points are (0,0) and (100, -800)

m = (y2-y1)/(x2-x1) = (-800-0)/(100-0) = -8

point slope form of the line is

y-y1 = m(x-x1)

y-0 = -8 (x-0)

y=-8x

this is in slope intercept form now

y=-8x

Which of the following is the most important piece of information to consider when comparing prices?
nataly862011 [7]

<em>Answer: A) The average price of the two items you are comparing.</em>

<em>Step-by-step explanation:</em>

<em>Because...</em>

<em>When a person goes to a store they look at a item and then compare prices. So for every person price is the important thing that you are comparing. It also depends on your income as well.  So choice A and C is almost the same. </em>

<em>Therefor, the correct answer would be A. </em>

<em>* Hopefully this helps:) Mark me the brainliest:)!!!</em>

How would I get the two equations into point intercept form?
prisoha [69]
Identify the slope, m. This can be done by calculating the slope between two known points of the line using the slope formula.
Find the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.

Hey guys not good at math please help
faust18 [17]

Answer:

3/2

Step-by-step explanation:

Recall that slope is y2 - y1 / x2 - x1.

Excellent. The question provides us with two points: (2,4) and (0,1). We can insert these two points into our equation.

Slope = (4 - 1) / (2 - 0) = 3 / 2.

Hope this helps!
