M< 6 = m< 7 (vertical angles)
11x + 8 = <span>12x – 4
12x - 11x = 8 + 4
x = 12
so
m< 6 = </span>11x + 8
m< 6 = 11(12) + 8
m< 6 = 132 + 8
m< 6 = 140
m<4 = 180 - m<6
m<4 = 180 - 140
m<4 = 40
answer
<span>m<4 = 40</span>
Answer:
68 inches
Step-by-step explanation:
The chains are 5ft and 8 inches long.
Your answer must be in inches, so convert any non-inch units to inches.
5 ft * 
= 60 inches
60 inches + 8 inches = 68 inches
Answer:
10
Step-by-step explanation:
The number of different ways that 2 lights can be chosen from 5 is ₅C₂. Use a calculator or find the value manually:
₅C₂ = 5! / (2! (5−2)!)
₅C₂ = 5! / (2! 3!)
₅C₂ = 5×4×3×2×1 / (2×1 × 3×2×1)
₅C₂ = 5×4 / 2
₅C₂ = 10
To calculate any speed, the equation is speed=distance/time
Basically, you first need to take your 9 hours and 15 minutes and combine them into a number with a decimal value.
So, 15*4=60
Sound familiar? Good, because 25*4=100, so they are the same here.
So, we can say 9 hours and 15 minutes is equal to 9.25
Take this now: Speed=538/9.25
You get 58.1621, which you can round to 58.2
This is, of course, your final answer, so Joe drove at 58.16 mph
