Answer:
x = 4
Step-by-step explanation:
The 2 graphs have the same output, y = 3 at the point of intersection
This occurs when the input is x = 4
You may use direct substitution to solve for x and y.
So, x=2 and y=4.
Answer:
The use of simile is how you get that answer.
Step-by-step explanation:
Answer:
(a) 36.36%
(b) 0.36%
(c) 0.06%
Step-by-step explanation:
Given that the time intervals measured with a stopwatch have an uncertainty of about 0.2 s.
We want to know what is the percent uncertainty of a hand-timed measurement of:
(a) 5.5 s
Percentage = (0.2/5.5) × 100
≈ 36.36%
(b) 55 s
Percentage = (0.2/55)×100
≈ 0.36%
(c) 5.5 min
5.5 min = 5.5 × 60 s
= 330 s
Percentage = (0.2/330)×100
≈ 0.06%
0.25x + 0.10y = 0.15*15
X + Y = 15
Y = 15 - X
0.25X + 0.10(15 - X) = 2.25
0.25X + 1.5 - 0.10X = 2.25
.15X = 0.75
X = 5
Y = 15 - 5
Y = 10
