Answer:
<h2>The construction crew has a speed of 2.75 feet per hour.</h2>
Step-by-step explanation:
In this problem, we have to find the unit rate, that is, the distance deep per hour, which can be also determined as the speed of the crew.
We know that after 3 hours, the hole is 8.25 feet deep. To find the unit rate we need to divide
Therefore, the construction crew has a speed of 2.75 feet per hour, that's the unit rate.
Answer:
The correct answer is y = 0.550 × x + 75.
Step-by-step explanation:
The slope intercept form of a straight line is given by y = m × x + c, where m is the slope of the line; a and y are the two variables and c is the constant.
Let the total number of tickets sold by me is x and my the total money I make by selling tickets is $y.
For signing up to sell tickets, I receive a fixed payment of $75. Thus, this is my fixed income and is not dependent on how much tickets I sell. Thus c = 75.
For every ticket I sell, I get a $0.550 per ticket. Thus total income by selling x number of tickets is given by 0.550 × x. This is my variable income and depends on how many tickets I sell (more I sell, implies more I earn and vice versa).
Thus the total money made by me or rather my total income (y) is given by summing up my variable income and fixed income.
Therefore, y = 0.550 × x + 75.
Answer:
-7/9
Step-by-step explanation:
the slope of a line between two points is 'rise over run', or the vertical distance between the points divided by the horizontal distance between them.
Finding the change in either direction is done by simply subracting our starting value from our ending value. It does not matter which point you start at, but lets choose (-6,-7) as our starting point, and (-24,7) as our end point.
The 'rise' of this line is 7 - (-7), which equals 14
The 'run' would then be -24 - (-6), which equals -18
Thus the slope is 14/(-18). Reducing this fraction gives us an answer of -7/9.
