Answer:
number of students in a van=12
number of students in a bus=52
Step-by-step explanation:
let number of students in a van=x
number of students in a bus=y
1x+6y=324 ...(1)
9x+3y=264 ...(2)
multiply (2) by 2
18x+6y=528 ...(3)
(3)-(1) gives
17x=204
x=204/17=12
put in (1)
12+6y=324
6y=324-12=312
y=312/6=52
Answer:
183.6 miles
Step-by-step explanation:
Kindly check the picture attached for the solution diagram
Using the cosine formula (Diagram has two sides and an included angle)
x² = y² + z² - 2zy * cosX
x² = 150² + 60² - 2(150*60) * cos115
x² = 22500 + 3600 - 18000 * −0.422618
x² = 22500 + 3600 + 7607.1287
x² = 33707.128 miles
x = √33707.128
x = 183.59501
x = 183.6 miles
Answer:
50 % probability that the hat is blue.
Step-by-step explanation:
3 blue and 3 black = 6 total tickets
3/6 chance of blue and 3/6 change of it being black
3/6 = 1/2 = 0.5 = 50%
5x + 3 ≥ 10
3 is adding on the left, then it will subtract on the right
5x ≥ 10 -3
5x ≥ 7
5 is multiplying on the left, then it will divide on the right
x ≥ 7/5
x ≥ 1.4
Then, the smallest integer value of x is 2
