The ratio of students that ride the bus as compared to those that walk on 10:1. Does this school have more students that ride th

NeTakaya

Answer: Yes they do.

Step-by-step explanation:

This because the ratio 10:1 means that for every 10 students that ride the bus only one walks. So if you had 30 students riding he bus you would only have 3 students that walked. So no matter what you will have more kids riding the bus.

Answer:

 x = 90, 199.5, 270, 340.5 degrees

Step-by-step explanation:

cos2x + 2sinx = sin^2x

Change cos2x to 1 - 2sin^2x:

1 - 2sin^2x + 2 sinx = sin^2x

Shift the terms to make it a quadratic equation:

3 sin^2x - 2sinx - 1 = 0

Factorise the quadratic equation:

(sinx - 1)(3sinx + 1) = 0

sin x = 1 or sin x = -1/3

Solve for sin x = 1:

From graph of sin x, x = 90 and 270 degrees when sin x = 1.

x = 90, 270 degrees

Solve for sin x = -1/3

Sin x = -1/3

Basic angle = sin inverse (1/3)

= 19.471 degrees

Since sin x < 0, x is in the 3rd or 4th quadrant

x = 180 + 19.471, 360 - 19.471

x = 199.5, 340.5

Hence, x = 90, 199.5, 270, 340.5 degrees

A one-way bus ride costs $1.75. A 30-day bus pass costs $42. When is the 30-day pass a better deal?

motikmotik

Answer:

After 24 days.

Step-by-step explanation:

42 Dollars / 1.75 Dollars per day = 24 Days. This means that at 24 days, the one-way bus ride costs as much as a 30-day pass. After 24 days, the 30-day pass is cheaper.
