bill amount paid = mp -d

= 1500 - 300

Answers

Answer:

100 degrees

Step-by-step explanation:

You can get the measure of b by knowing that a straight line is 180 degrees. So the interior angle formed at R is 40 degrees. That makes the angle at p 40 degrees. The interior sum of a triangle is 180 degrees.

So 40+40+angle at a = 180

angle at a = 180-80 = 100 degrees.

100 degrees

Step-by-step explanation:

180-(180-((180-116)+103))

Answer: I think it might be y = 180 - 52 - 59 = 69 degrees . . . . . . . . (angles on a straight line are supplementary, i.e. add up to 180 degrees)

x = 180 - 69 - 63 = 48 degrees . . . . . . . . (sum of interior angles of a triangle is 180 degrees)

Therefore, m/_x = 48 degrees.

Blanking on how medians in a triangle work

Answers

A median cuts a leg of a triangle in half. So for instance, PF being a median means that DP and PE are congruent and have the same length. Consequently, each component triangle (that is, ∆DPC, ∆EPC, ∆EQC, etc) all have the same area.

If A is the area of ∆PCE, then the area of ∆PFE is 3A.

Take PF = 24 to be the base of ∆PFE, and take PC to be the base of ∆PCE. The area of any triangle is equal to 1/2 times the base times the height. But ∆PFE and ∆PCE share the same height (you can see this by dropping an altitude from the vertex E down to the line containing PF), so PC is 1/3 the length of PF, so FC must be 2/3 the length of PF.

So FC has length 2/3 × 24 = 16.

L: 465ft.

Step-by-step explanation:

65+65+465+465=1060

2(400+w) +2w = 1060
800 + 2w + 2w = 1060
800 + 4w = 1060
4w=260
w=65

The function f(x) varies inversely with x and f(x)=0.5 when x = 0.15.
What is f(x) when x = 2.5?

Answers

Answer:

0.03

Step-by-step explanation:

Standard equation of inverse variation:

y = k/x

In function notation it is

f(x) = k/x

We are given f(0.15) = 0.5

0.5 = k/0.15

k = 0.5 * 0.15

k = 0.075

The function is

f(x) = 0.075/x

For x = 2.5,

f(2.5) = 0.075/2.5

f(2.5) = 0.03
