Matthew drove miles in hour. What was Matthew’s average speed?
1 answer:
Answer: Use the formula (SEE EXPLANATION)
Step-by-step explanation:
Since the exercise it is incomplete, I will give you a general explanation about how to solve this problem so you can find the solution.
For this exercise it is important to remember that , by definition the average speed is a scalar quantity that can be calculated dividing the Total distance divided by the Elapsed.
It is also important to know that the Elapsed time is defined as the time it takes the object to cover the total distance.
Therefore the Average speed can be calculated with following formula:
Then, knowing the values of the Total distance and the Elapsed time, you can substitute those values into the formula and then evaluate.

<em><u>Solution:</u></em>
Given that,
Cost of 1 cap = $ 5
Cost of 1 t-shirt = $ 10
Let "x" be the number of caps sold
Let "y" be the number of t-shirts sold
The drama club needs to raise at least $500.00 for the trip
Based on this information, we can frame a inequality as:
number of caps sold x cost of 1 cap + number of shirts sold x cost of 1 shirt 500
Which means,
Here we used "greater than or equal to" symbol , because club needs to raise at least $ 500
They can raise 500 or more than $ 500 also
Thus the required inequality is
Answer:
The angle that the line makes with x-axis of of 64.3º.
Step-by-step explanation:
Equation of a line, and angle with the x axis:
The equation of a line has the following format:
In which m is the slope.
The angle that the line makes with the x axis is given by the angle which has tangent m, that is, .
In this question:
We have that . So
The angle that the line makes with x-axis of of 64.3º.
