Multiples of 2: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28
Multiples of 3.5: 3.5, 7, 10.5, 14, 17.5, 21, 24.5, 28
Multiples of 4: 4, 8, 12, 16, 20, 24, 28
The least common multiple of the 3 numbers is 28, so the lights will flash at the same time every 28 minutes.
The time will be 8:28 PM
Answer:
35h + 15m
Step-by-step explanation:
<u>Step 1: Distribute</u>
5(7h + 3m)
<em>35h + 15m</em>

Answer: 35h + 15m
Remark
The slope intercept line is written as y = mx + b in it's general form.
You can get the slope, m, immediately because it is given as -2
So far what you have is y = -2x + b
y intercept
To get the y intercept, use the point (-3 , 4)
x = - 3
y = 4
4 = -2*(-3) + b
4 = 6 + b Subtract 6 from both sides
4 - 6 = 6-6 + b
b = - 2
Line
y = -2x - 2
(a,8)
y = -2a - 2
8 = -2a - 2 Add 2 to both sides
8 +2 = -2a -2+2 Combine
10 = - 2a Divide by - 2
10/-2 = a
a = -5
(5,b)
x = 5
y = b
b = -2*5 - 2
b = -10 - 2
b = - 12
Option D is correct.
We need to find the value of sin 34°.
We can find the value by putting it in the calculator
sin 34° = 0.5592
So, Option D is correct.
C
0 ≤ h ≤ 40, h ∈ R
