Ratio and proprtion
number of prized to price is 5 to 80 or 5/80 which can be simplified to 1/16
1 price to 16 cents equals 250 prizes to x cents
1/16=250/x
times both sides by 16x aka cross multiply
x=250*16
x=4000 cents or $40 for 250 prizes

  • [Right Triangles Only] cosθ = adjacent over hypotenuse
  • Inverse Trig

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify variables</em>

Angle θ = ?

Adjacent Leg = 13

Hypotenuse = 20

<u>Step 2: Find Angle</u>

  1. Substitute in variables [cosine]:                                                                   cosθ = 13/20
  2. Inverse Trig:                                                                                                    θ = cos⁻¹(13/20)
  3. Evaluate:                                                                                                         θ = 49.4584°

Problem
Paraphin [41]

Answer:

45/126 or 5/14

Step-by-step explanation:

a / b = 5/8

b / c = 9/14

a = 5

b = 8

b = 9

8 * 9 = 72

b = 72

If b was = 8 and now = 72, multiply a by 9.

b = 45

If b was 9 and now is 72, multiply c by 9.

c = 14 * 9 = 140 - 14 = 126


b / c = 45/126 or 5/14

You are welcome!

choli [55]

Answer:

<h2>A. the slope is 8.</h2><h2>A. the y-intercept is 1</h2>

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y = mx + b

m - slope

b - y-intercept

We have the equation y = 8x + 1.

Therefore:

m = 8, b = 1
