Answer:

2

Step-by-step explanation:

1. Find the difference between the two y values. 5 − 1 = 4

  This is usually called the "rise" of the line.

2. Find the difference between the two x values. 4 − 2 = 2

   This is usually called the "run" of the line.

3.  Divide the rise buy the run: \frac{rise}{run} = slope \frac{4}{2} = 2

Answer:

use y2 - y1 / x2 - x1

5 - 1 / 4 - 2 = 4/2 = 2

Determine the number of possible triangles, ABC, that can be formed given angle A = 30°, a = 4, and b = 6.
Sophie [7]

Answer:

Step-by-step explanation:

Alright, lets get started.

using Sine Law,

\frac{sinA}{a}=\frac{sinB}{b}

\frac{sin30}{4}=\frac{sinB}{6}

sinB=0.75

angle B = 48.6

Another angle will be

angle B' = 180-48.6 = 131.4

considering angle B, angle C = 180 - (48.6+30)=101.4

considering angle B', angle C' = 180-(131.4+30)=18.6

\frac{sinA}{a}=\frac{sinC}{c}

\frac{sin30}{4}=\frac{sin101.4}{c}

c = 7.84

Similarly, finding c'

\frac{sinA}{a}=\frac{sinC'}{c'}

\frac{sin30}{4}=\frac{sin18.6}{c'}

c'=2.55

Hence two triangles are possible with below details:  :   Answer

A = 30, B = 48.6, C = 101.4, c = 7.84

A = 30, B' = 131.4, C' = 18.6, c' = 2.55

Hope it will help :)

Ben needs to buy orange juice. He can buy 64 fl oz at the grocery store for $2.00, or he can buy 256 fl oz at the wholesale club
crimeas [40]
Unit price so compare
2 gets 64 or 7.50 get 256
grocery store  2:64=1:32=32 oz per $1
wholesale club  7.5:256=1:34.133=34.133 oz per $1
wholesale club gets you more oz of juice for the same price

A: 32 oz per $1 or $0.031 per 1 oz
B: 34.133 oz per $1 or $0.029 per 1 oz
C: best deal is at wholesale club

after a 20% discount , the price of a super slick skateboard is $140 what was the price before the discount
Juliette [100K]
A good way to set up percentage problems is by using "Part = Percent × Whole".
In this case, our part is 140, our percent is 80 (because that 20% wa s took of from the original 100%), and our whole is unknown. If we fill in the equation we get this:
140=80×x.
if we solve the equation by dividing both sides by 80, we get $1.75=x. Because we replaced 80% with 80,we have to divide by 100 since we multiplied by 100 in the beginning. So, we get that $175 was the original price.
