What Is The Answer To C

Answers

Answer 1

Answer:

C = 15

Step-by-step explanation:

Both (7c-7)° & (6c-8)° if get combined will form a straight angle i.e. 180° because both the angles lie on the same line. So,

[tex]7c - 7 + 6c - 8 = 180°[/tex]

[tex] = > 13c - 15 = 180°[/tex]

[tex] = > 13c = 180 + 15 = 195[/tex]

[tex] = > c = \frac{195}{13} = 15[/tex]

Question 4(Multiple Choice Worth 6 points)
(03.04 LC)

Write the equation of the graph shown below in factored form.

the graph starts at the bottom left and continues up through the x axis at negative two to a maximum around y equals eight and goes back down through the x axis at one to a minimum around y equals negative four and back up through the x axis at three

f(x) = (x + 2)(x − 1)(x − 3)
f(x) = (x − 2)(x + 1)(x + 3)
f(x) = (x + 2)(x + 1)(x + 3)
f(x) = (x − 2)(x − 1)(x − 3)

Answer:   Perimeter of triangle ROA = 33

=================================================

Explanation:

Points R, O, and A are midpoints of sides XY, YG, and XG respectively.

Because of this, we know that the points cut those sides into two equal halves.

To elaborate, we know the following three facts:

Point R is the midpoint of XY, so XR = RYPoint O is the midpoint of YG, so YO = OGPoint A is the midpoint of XG, so XA = AG

The diagram shows that YO = 14, so OG must be 14 units long as well.

The diagram also shows XA = 8. Since XA = AG, we know that AG = 8.

-----------------------------

Use this information to find the perimeter of triangle XYG.

Perimeter of XYG = sum of all the sides

Perimeter of XYG  = (XY) + (YG) + (XG)

Perimeter of XYG  = (22) + (YO+OG) + (XA+AG)

Perimeter of XYG  = 22 + (14+14) + (8+8)

Perimeter of XYG  = 66

-----------------------------

Then we cut this in half to get the perimeter of triangle ROA.

We do this because each segment of ROA is half that of the corresponding segment of XYG. The midsegments (RA, RO, AO) are cut in half and are parallel to the opposite side.

So,

Perimeter of ROA = (1/2)*(Perimeter of XYG)

Perimeter of ROA = (1/2)*(66)

Perimeter of ROA = 33

13-2(4r-5) =-(7+8r) please show work

Answers

Answer:

r = no solutions

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDASEquality Properties

Step-by-step explanation:

Step 1: Define equation

13 - 2(4r - 5) = -(7 + 8r)

Step 2: Solve for r

Distribute:                              13 - 8r + 10 = -7 - 8rCombine like terms:              -8r + 13 = -7 - 8rAdd 8r on both sides:           13 ≠ -7

Here, we see that 13 does not equal -7. ∴ r has no solutions.

Suppose that when a skunk sprays, the odor has a half-life stink potency of
8 hours. This means that the skunks spray would have a stink odor of 100%

day? Explain/show your work.

Answer:

12.5% Potency
