Sep-by-step explanation:
Answer:
Jacob finished the race faster than Daniel.
Step-by-step explanation:
We have that,
Daniel completed the hurdle in of a minute i.e. 75% of a minute.
Jacob completed the hurdle with remaining of a minute i.e. 41.7% remaining of a minute.
Now, as we have that,
75% of a minute = 45 seconds
41.7% of a minute = 25 seconds
Since, Jacob had time remaining.
Thus, Jacob had = 60 - 25 = 35 seconds remaining.
So, Daniel ran in 45 seconds and Jacob ran in 35 seconds.
Hence, we get that, Jacob finished the race faster than Daniel.
Jacob
Given:
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.

When a line of symmetry divides an image, every point on one side of the line has a corresponding point on the other side is true.
To find true/false When a line of symmetry divides an image, every point on one side of the line has a corresponding point on the other side.
A line of symmetry is a line that cuts a shape exactly in half.
A line of symmetry divides a design so that every point on one side of the line coincides with a point on the other side of it. There are figures and shapes that can have more than one lines of symmetry. A circle has infinite lines of symmetry. Likewise, a triangle has three lines of symmetry, while rectangle and square have four such lines which divide them into identical parts.
so, a line of symmetry divides an image, every point on one side of the line has a corresponding point on the other side is true.

= 3 hours : 45 minutes
= (3 hours)/(45 minutes)
We know, 1 hour = 60 minute, 3 hours = 3 × 60 minutes = 180 minutes,
= (180 minutes)/(45 minutes)
= 180/45
= 4/1
= 4 : 1
