Step 1: Add together the known angles.
Step 2: Subtract the sum from 180°.
Answer:
The true statements are:
The cost of 9 magnets is $3.
The cost of 6 magnets is $2.
The cost of 3 magnets is $1.
Step-by-step explanation:
equivalents ratios are two or more ratios that express the same relationship between the numbers involved. In order to calculate the equivalent ratios that are equal, when the numbers involved are divided, they ought to give the same result. In the answer chosen above the ratios in each case are equivalent because:
if the cost of 9 magnets is $3;
9 magnets = $3
∴ 1 magnet = 3/9 = $ 1/3 = 1:3
if the cost of 6 magnets is $2;
6 magnets = $2
1 magnet = 2/6 = $1/3 = 1:3
if the cost of 3 magnets is $1;
3 magnets = $1
∴ 1 magnet = $ 1/3 = 1:3
From the answers obtained, the equivalent ratio of 1 : 3 is the same in all case.
It doesn't add up to 360 degrees
Answer:
y=-1/4x+4
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(5-8)/(-4-(-16))
m=-3/(-4+16)
m=-3/12
m=-1/4
y-y1=m(x-x1)
y-8=-1/4(x-(-16))
y-8=-1/4(x+16)
y-8=-1/4x-16/4
y-8=-1/4x-4
y=-1/4x-4+8
y=-1/4x+4
