Answer:

  • van: 8
  • bus: 22

Step-by-step explanation:

If we let v and b represent the seating capacity of vans and buses, respectively, then the two trips can be described by ...

  8v +8b = 240

  4v +b = 54

Dividing the first equation by 8 gives ...

  v +b = 30

Subtracting that from the second equation gives ...

  3v = 24

  v = 8 . . . . . . . . . . . divide by 3

  b = 30 -8 = 22

The number of students in each van is 8; the number in each bus is 22.

If a point is chosen inside the square, what is the probability that it will also be inside the circle?
Feliz [49]

Answer:

79\%

Step-by-step explanation:

The probability that the point is chosen in the circle is equal to the area of the circle divided by the area of the square.

Formulas used:

  • Area of a square with side length s is given by A=s^2
  • Area of a circle with radius r is given by A=r^2\pi

The segment marked as 1 represents not only the radius of the circle, but also half the side length of the square. Therefore, the side length of the square is 2, and we have:

Area of square: A=2^2=4

Area of circle:

A=1^2\pi=\pi

Therefore, the probability that the point will be inside the circle is:

\frac{\pi}{4}=0.78539816339\approx \boxed{79\%}

DIA [1.3K]

Answers:

  • A) 1/2
  • B) 1/6
  • C) 1/3

==================================

Explanation:

  • A) There are 3 copies of '1' out of 6 slices total. So we get 3/6 = 1/2
  • B) There's only one copy of '3' out of 6 total, which means 1/6 is the probability of landing on '3'.
  • C) There are 2 places we want to land out of 6 total. The probability is 2/6 = 1/3

How to solve 5x-4y=7 <br> 2y+6x=22 as a system of equations
ira [324]

Step-by-step explanation:

you subtract -4 by 7.

then you hav 5x=7

you divide 5x by 5 and seven by five so your x= that answer

then you put that number into the x in the second equtaion

then you subtract that number after multiplying the 6 by the number x equals

then you divide 2y by 2 and 22 by 2 and thats your y value
