Answer:
A) Amanda will pay $47.5
B) 0.5
C) $120
Step-by-step explanation:
A) From the graph given, at 45 miles, the total cost of rentage = $142.50
She now splits this cost with 2 of her friends. Thus each of them will pay;
Amount = 142.5/3 = $47.5
So,Amanda will pay $47.5
B) To find the slope, we will pick two points on the graph and use their respective coordinates to find the slope.
Coordinates we pick are;
(0, 120) and (50, 145)
Thus, slope; m = (y2 - y1)/(x2 - x1)
m = (145 - 120)/(50 - 0)
m = 25/50
m = 0.5
C) The equation for the graph will now be; y = mx + c
Where m is slope and c is y - intercept.
Thus;
y = 0.5x + 120
Coincidentally, c = 120 will be the fixed price of the truck while 0.5x will be the variable cost depending on how many miles are driven.
Thus renting for a day is simply the fixed cost of $120
Answer:
68.57mph
Step-by-step explanation:
with decimals, well, 3/4=0.75 (just divide 3/4 and you'll see) and 1 3/4 = 1.75
Then you divide 120/1.75 and there you go, 68.57mph
If you're supposed to do it with fractions:
1 3/4 = 4/4 + 3/4 = 7/4
Then you divide 120 / 7/4 (remember 120 = 120/1
Which means you have to cross multiply (an important part on fraction division, that is, your division would be 120x4 / 1x7).
Then 120x4= 480
And 1x7 = 7
Then you get 480/7, which is the same as 68 4/7 mph
Answer:
Step-by-step explanation:
Answer:
$2374.15 per week
Step-by-step explanation:
there are 52 weeks per year, so what you need to do is divide 52 by 123,456
123,456/52=$2374.15
