You go to a Christmas fair with a big Ferris wheel. The wheel has ten seats, and two people are placed on each seat. Every minut
monitta

60 people have ridden the wheel in 30 minutes

The time is given as:

Time =30 \minutes

The number of seats on the wheel is given as:

Seats = 10\\

The number of people on a seat is given as:

People =2

Every minute a seat exits the platform.

This means that, 2 people exit the platform every minute

So, the number (n) of people that exit the platform after 30 minutes would be:

n =People \times Time

This gives

n = 2\times 30

Multiply

n = 60

Hence, 60 people have ridden the wheel

Equation of a line, in general form, that is perpendicular to 2x-3y + 7 = 0 and passes through the point (-3/4, 1)
TEA [102]

Answer:

  12x +8y +1 = 0

Step-by-step explanation:

You can write the equation by swapping the x- and y-coefficients and negating one of them. Then compute the constant that makes the line go through the given point. You can do that like this:

  3(x-(-3/4)) +2(y -1) = 0

  3x +9/4 +2y -2 = 0 . . . . eliminate parentheses

  3x +2y +1/4 = 0 . . . . . . . simplify

To eliminate the fraction, multiply by 4:

  12x +8y +1 = 0

_____

<em>Comment on the equation</em>

The line ax+by=0 passes through the origin. Replacing x and y with x-h and y-k, respectively, makes the line pass through the point (h, k). That's what we did above to make the line pass through the given point.

The business of swapping coefficients and negating one causes the slope of the new line to be the negative reciprocal of the slope of the original line. That is what makes the new line perpendicular to the original.

Who know how to do surface area of cylinders? Really need help
DiKsa [7]

Answer:

To find the surface area of a cylinder add the surface area of each end plus the surface area of the side. Each end is a circle so the surface area of each end is π * r2, where r is the radius of the end. There are two ends so their combinded surface area is 2 π * r2.
