Answer:
12.16
Step-by-step explanation:
1:Reduce the fraction 100 38 to lowest terms by extracting and canceling out
2:Express 50/19 ×32 as a single fraction.
3:Multiply 19 and 32 to get 608.
4:Reduce the fraction 608/50 to lowest terms by extracting and canceling out 2.
5:304/25=(12.16).
Answer:
49 cars
Step-by-step explanation:
Probability of cars to be sold in a week,a = 0.2
Probabiity of cars not sold in a week, b = 0.8
Number of cars estimated to be sold in a week = 20 and 60 cars in 3 weeks
Using, P(x) = nCx *(a)∧x * (b)∧n - x, where n = 3 weeks, x = 1 week
P(x=1) = 3C1 * (0.2) * (0.8)² = 3 X 0.2 X 0.64 X 60 cars = 23 cars
P(x=2) = 3C2 * (0.2)² * (0.8) = 3 X 0.04 X 0.8 X 60 cars = 6 cars
Number of cars three weeks from now: 20 + 23 + 6 = 49 cars
It would take you 15 minutes. Since one hour equals 60 minutes your equation would look like this:
4x=60
So you need divide 4 into both sides in order to find the value of x which represents one mile.
So one mile takes 15 minutes to walk or x=15.
The answer to this question is false
Answer:
290 in²
Step-by-step explanation:
Using the net of the box given, we can see that there are 4 equal rectangles and 2 equal squares that make up the prism.
Area of the 4 rectangles = 4(60) = 240 in²
Area of the 2 squares = 2(25) = 50 in²
Therefore,
Surface Area of the prism = 240 + 50 = 290 in²
