Answer:
1. C(m) = 24.95 + 0.05m
2. $34.95
3. 250 miles
Step-by-step explanation:
1. Let's say C(m) is a function that determines the Cost in $ for every mile you drive. Since for any rental, no matter if you drive or not, you have to pay an upfront cost of rental, r, there is a constant you need to add ($24.95 in this case.)
2. Use your equation from part 1 to get C(200) = 24.95 + 0.05(200), this equalts 34.95 dollars.
3. Here, you want to find m (distance). It is given that C(m) = 37.45 (this is the total cost from equation (1). Subtract 24.95 from C(m) to isolate the 0.05(m) part. Thus, 0.05(m) = 37.45 - 24.95 = 12.5. Here, simply divide 12.5 by 0.05 to obtain m, which is 250 miles.
Step-by-step explanation:
If we can apply rigid transformations to the polygon for example, rotating the polygon, Translating the polygon, or reflecting the polygon , and we get a new image of A ppolygon, then the polygon will be congruent.
Order of operations is Parentheses, Exponents, Multiplication and Division (left to right), Addition and Subtraction (left to right)
7 + 6[-2] - 5
First, multiplication. Multiply 6 by -2. You get -12
7 - 12 - 5
Now, all that’s left is subtraction. Subtract from left to right, so subtract 7 and 12 first. 7-12= -5
-5 - 5
Now just solve the rest of it. -5 minus 5 is -10.
The final answer is -10

<u>Answer:</u>
The driver should travel at a Speed of 50 mph so that the average speed of the entire trip is 45 mph
<u>Step-by-step explanation:</u>
Given:
Total distance=100 mi
Speed at which the driver travels the first 50 mi= 40 mph
To Find:
Speed at which the driver should travel so that the average speed of the entire trip is 45 mph=?
Solution:
Average speed:
The average speed of an object is the total distance travelled by the object divided by the elapsed time to cover that distance. It's a scalar quantity which means it is defined only by magnitude. A related concept, average velocity, is a vector quantity. A vector quantity is defined by magnitude and direction.
Let X be the distance at which driver should travel so that the average speed of the entire trip is 45 mph
From The given data we get,
X=50
