Answer:
1) B. -2 hours per person
2) C. 3.60 per pound
Step-by-step explanation:
1)
We can make a slope triangle connecting the points (4, 12) and (10,0)
We get -12/6, or -2 as our slope & final answer
2)
You can do x/y to find the unit rate for this one, or in this case 18/5 = 3.6
Answer:
The answer is -5.
Step-by-step explanation:
As you look at the first 3 terms, all have the common difference of 4. So the next term after -1 is :
19 - 4 = 15
15 - 4 = 11
11 - 4 = 7
7 - 4 = 3
3 - 4 = - 1
- 1 - 4 = - 5
When we have a right triangle with sides and angles, we use basic trigononemetry. Since we know the vertical leg (height of ramp) and horizontal leg (base length of ramp), we use the inverse tangent function to find the angle.
θ = tan-1(height of ramp / base of ramp) θ = tan-1(2.5 / 6) θ = tan-1(5 / 12)
