Mark jogged 3 and5/7 km. His sister jogged 2 and 4/5 km. How much farther did mark jog?
katovenus [111]

Answer: 32/35 km

Step-by-step explanation: First you have to find a common denominator between these two mixed numbers. That basically means that you have to convert them so that they both have the same denominator, that way they can be compared to one another. The easiest way to do this is to just multiply the denominators. 5 x 7 = 35. I will use 35 as my denominator. Then you multiply the numerators by the same number that you multiplied the denominator by to get 35. Since 7 x 5 = 35, 5 x 5 = 25. Same with the second fraction. 5 x 7 = 35. 4 x 7 = 28. The mixed numbers we have are now 3 and 25/35 and 2 28/35. To figure out how much farther Mark jogged we just take his distance, and subtract his sister's distance from it. 3 25/35 minus 2 28/35 = 32/35.

The number of ferryboat trips r(c) needed to transport c cars in 1 day can be found using the function f(c)=c/20. If there are n
xz_007 [3.2K]
<h2>Hello!</h2>

The answer is:

The range of the given function, f(c) is

f(c)\leq 250

<h2>Why?</h2>

To solve the problem we need to remember that a function is a relationship between an input usually called "x" (domain) and an output, usually called "y" and it's also the range of the function.

f(x)=y

We are given a relationship (a function) between the ferryboat trips "c" and the number of cars transported per day.

f(c)=\frac{c}{20}

Also, we know that there are not more than 5000 cars transported by the ferryboat, so, let's make this value our input, in order to find the output (range) of the given function.

So, if

c=5000

Evaluating, we have:

f(5000)=\frac{5000}{20}=250

Hence, the range of the function knowing that there are not more than 5000 cars transported by the ferryboat (daily) the range is all the numbers that are less or equal to 250.

f(c)\leq 250

Have a nice day!

The sum of angles in a triangle also adds up to 180°.

Step 1: Find measures interior angles.

3x = 180
