Simplify the fraction below.

35/4

Answers

Answer:

8 3/4

Step-by-step explanation:

find the greatest common factor of 35 and 4, which is 1.  Then divide both 35 and 4 by the greatest common factor to get the following simplified fraction: 35/4

If the numerator is greater than or equal to the denominator of a fraction, then it is called an improper fraction. You could convert it into a whole number or mixed number fraction. Which would now be 8 3/4

(If its not right let me know so I can rethink my answer)

the start of the hike, a hiker was at -50 below sea level and climbs a rate of 15 feet per minute
Which of these inequalities describes this situation when the hiker's elevation was higher than 5 feet above sea level where t represents the number of minutes after the start of the hike?
A. -50 + 15t < 5
B. -50 + 15t > 5
C. 15 - 50t < 5
D. 15 + 50t > 5

Answers

Answer:

B. -50+15t>5

Paula is running a race that is 10 kilometers long. After running 8
minutes, she passes the 3.75 kilometer marker. How many more
kilometers does Paula need to run to cross the finish line?

Answers

Answer:

10-3.75= 6.25 more kilometers

Step-by-step explanation:

The number of kilometers that Paola needs to run to cross the finish line will be 6.25 kilometers.

What is the length?

It is the measure of distance between the two points and is known as length. The length is measured in meters generally.

It simply implies subtracting something from an entity, group, location, etc. Subtracting from a collection or a list of ways is known as subtraction.

Paula is running a race that is 10 kilometers long. After running for 8 minutes, she passes the 3.75 kilometers marker.

Then the number of kilometers that Paola needs to run to cross the finish line will be given by the difference of 10 km and 3.75 km.

⇒ 10 - 3.75

⇒ 6.25 kilometers

Thus, the number of kilometers that Paola needs to run to cross the finish line will be 6.25 kilometers.
