Since they all begin with 2, you need to look for the biggest number after the decimal point, since it's 4 then 2.4 is the biggest number
At a track meet, Jacob and Daniel compete in 220 m hurdles.
Daniels finishes in of the a min.
Jacob finishes with of a min remaining.
Question:
Who ran the race in faster time?
The Process:
Let us see the denominators. The least common multiple (LCM) of 4 and 12 is 12.
Let us draw the diagram that represents a minute.
12 units represent in one minute.
Daniels finishes in of the a min.
or 9 of 12 units.
Jacob finishes with of a min remaining, or 5 of 12 units. This means Jacob finishes in or 7 of 12 units, that is
And now we conclude who ran the race in a faster time.
Daniels:
Jacobs:
Because Jacob took the race in a shorter time, he was who ran the race in a faster time.
- - - - - - - - - -
Quick Steps
Daniels: in of the a min.
Jacob: in of the a min.
Jacob's time is shorter, so he's the fastest.
- - - - - - - - - -
Calculate the speed
Recall
Daniels:
Jacob:
Thus, Jacob's speed proved greater than Daniels's speed.
Answer:
No
Step-by-step explanation:
Um anyways i think that the answer would be C
Jessie needs 27 supporters in order to reach his goal.
Step-by-step explanation:
Given,
Amount to be collected by Jessie = $150
Jessie's contribution = $15
Amount to be asked from each person = $5
Let,
x be the number of people who contribute.
Jessie's contribution + 5*Number of people who contribute = Total amount
15+5x=150
Subtracting 15 from both sides
Dividing both sides by 5
Jessie needs 27 supporters in order to reach his goal.
