D) greater than 90 degrees

_____
An angle greater than 90 degrees will put it in the second quadrant, where the x-component is negative.

Answer:

Greater than 90 degrees.

Step-by-step explanation:

Let a vector R make angle \theta with the x-axis. Then, the component along the x-axis would be

R cos\theta

Component along y-axis would be

R sin\theta

For 0 both the components will be positive and lie in the first quadrant. If angle of vector is more than 90 degrees, one of the components would be negative. For example, angle between 90 to 180 degrees, x-component would be negative while between 180-270 degrees, both the components would be negative.

The inequality 10.45b + 56.50 < 292.67 is used to find the number of boxes (b) that can be loaded on a truck without exceedin
nordsb [41]

Question :

The inequality 10.45b + 56.50 < 292.67 is used to find the number of boxes (b) that can be loaded on a truck without exceeding the weight limit of the truck. The solution is written as {b | b < 22.6}. Which statement best describes the meaning of the solution?

The truck can hold more than 22 boxes.

The truck can hold more than 23 boxes.

The truck can hold up to 22 boxes.

The truck can hold up to 23 boxes.

Answer:

Option C: The truck can hold up to 22 boxes.

Explanation:

Given that the inequality is 10.45b + 56.50 < 292.67 is used to find the number of boxes can be loaded on a truck without exceeding the weight limit of the truck.

To determine the number of boxes, let us solve the inequality.

Thus, we have,

10.45b + 56.50 < 292.67

Subtracting both sides by 56.50, we get,

10.45b  < 236.17

Dividing both sides by 10.45, we have,

b

This means that the number of boxes that can be loaded on a truck without exceeding the weight limit of the truck should be lesser than 22.6

Therefore, the truck can hold up to 22 boxes.

Hence, Option C is the correct answer.
