Pythagorean Theorem is a² + b² = c²
Answer:
0.1 miles per minute
Step-by-step explanation:
The line goes through (0, 0), so Maria's speed is the ratio of miles to minutes:
(4.5 mi)/(45 min) = 0.1 mi/min
Answer:
m=1
y= 5
Step-by-step explanation:
since y=mx+b
y=1x+5
Answer:
x = 20 but see below.
Step-by-step explanation:
Remark.
This is not well enough marked to know whether D = A or whether you have to do some algebra to find the relationship between A and D. So I will assume A = D and then I'll solve it so you have to manipulate A and D.
A = D
3x - 10 = 2x + 10 Add 10 to both sides
3x - 10 + 10 = 2x + 10 + 10 Cancel
3x = 2x + 20 Subtract 2x from both sides
3x-2x=2x-2x + 20
x = 20
A = E
If A = E then to find x you have to add 3 angles together.
E + D + 45 = 180 Add the three angles of the triangle
E + D = 180 - 45 Subtract 45 from both sides
E + D = 135 Substitute for D and E
3x - 10 + 2x + 10 = 135 Combine like terms
5x = 135 Divide by 5
x = 135 / 5
x = 27
Answer
I'd go with the first one.
The answer will be for every x, y will be 1.25
