I don’t know but I need the Points sorry for you
The ratio of 2:9 has to be 2:9 do to the fact you can't simplify the fraction 2/9.
Hoped I helped.
Answer:
A) 14/9
Step-by-step explanation:
14 and 9 have no GCFs (Greatest Common Factors), so the ratio is simply 14/9.
<span>8 minutes 20 seconds.
First, lets determine who many miles per minute each vehicle moves by dividing each speed by 60.
Speeder = 60 / 60 = 1 mile per minute.
Police = 75 / 60 = 1.25 miles per minute.
Other car = 45 / 60 = 0.75 miles per minute.
Since the speeding car moves for 5 minutes before the police start to chase, that means that the speeding car will now be 5 + T miles down the road with T being the time the police has been chasing. The police will be 1.25 T. We're looking for when those two equations equal each other. So
5 + T = 1.25 T
Subtract T from both sides
5 = 0.25T
Divide both sides by 0.25
20 = T
So it will take the police officer 20 minutes to catch up to the speeder. And they will both have traveled a total distance of 25 miles from the point where the speeder passed the police car.
Now we need to figure out how far the law obeying car has moved during those 25 minutes. So
25 * 0.75 = 18.75 miles.
The distance the law obeying car needs to travel to catch up to the police officer then becomes
25 - 18.75 = 6.25 miles.
The number of minutes that the law obeying car needs to travel that distance is
6.25 / 0.75 = 8.333....
Which is 8 minutes 20 seconds.</span>
Answer:
7 1/7
Step-by-step explanation:
For the problem:
5
/7
× 10 = ?
Convert any mixed numbers to fractions:
10 = 10
Multiply all of the numerators by each other. Do the same with the denominators and form a new fraction with these values:
5 × 10
7 × 1
=
50
/7
50 ÷ 7 = 7R1, therefore:
50
/7
= 7 1/7
The result is:
