If m<1=40 and m<2=80, what is m<3?
prohojiy [21]

Answer:

60 degrees, 55 degrees, and 50 degrees respectively

Step-by-step explanation:

Equation: m<1+m<2+m<3=180

1. 40+80+x=180 Subtract 120(because 40+80=120)

  x=60

2. 50+75+x=180 subtract 125 (50+75=125)

    x=55

3. 50+80+x=180 subtract 130 (50+80=130)

   x=50

Starting at a fixed time, each car entering an intersection is observed to see whether it turns left (L), right (R), or goes str
docker41 [41]

Answer:

The possible X values are the natural numbers.

RRL: X=3

AARRL: X=5

AARL: X=4

RRAL: X=4

ARL: X=3

Step-by-step explanation:

Since we are going to observe the cars and the experiment will end when one of them turns left, and X is the number of cars observed, the possible X values will be the natural numbers (1,2,3....). Clearly we can observe any number of cars before one of them turns left. We cannot observe negative numbers of cars, or zero cars (We are going to observe at least one car), or fractions of cars.

Given the outcomes below, find their associated X values:

For this part of the problem, we are going to count how many cars we observed in total and that will be the X value.

RRL: X=3

AARRL: X=5

AARL: X=4

RRAL: X=4

ARL: X=3

A 25,000-gallon swimming pool needs to be completely drained for maintenance purposes.
egoroff_w [7]

Answer:

A: 1800h-25,000

B: Yes, he would have time.

Step-by-step explanation:

A:

Lets turn 30 gallons/minute into hours so we can make it easier.

18000h-25000

Then plug in h which is hours. To get your answer

B:

From May 7 at 8:00 a.m. to May 8 at 12 p.m. would be 28 hours.

So we plug in 28 for h and get our answer of 25400 gallons/hour
