Answer:
905
Step-by-step explanation:
365+540=905
Answer:
D) 10x-20
Step-by-step explanation:
P = 2w + 2l
= 2(2x-8) + 2(3x-2)
= 4x-16 + 6x-4
= 10x-20
The question asks us to find the area of a triangle. First, before we do anything, we need to state the formula for the area of a triangle, which is
, where
is the base and
is the height. In this scenario, we are given the length of the height, which is
. We need to find the length of KL, which is the base. We can see that this triangle is a 30, 60, 90 degree triangle, meaning that it has some special properties. First off, it means that the hypotenuse is two times the side opposite to it, which in this case is that AL (the hypotenuse) is two times the length of AK, which is the side opposite to it. Thus, the length of the hypotenuse is
. Now, we can use the Pythagorean Theorem to find the length of the base.
Now that we found all the required values for the formula, just plug it in and solve. When we do so, we get that the area is
. Hope this helped!
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.
