Answer:
Explanation:
Use the Pythagorean theorem (
a
2
+
b
2
=
c
2
)
Lets label the right triangle such that:
a
=
12
b
=
16
c
=
x
Thus,
12
2
+
16
2
=
x
2
144
+
256
=
x
2
400
=
x
2
√
400
=
x
20
=
x
So our missing side,
c
is
20
We can now say that the sides of our triangle are
12
,
16
,
20
I've included a link that lists a couple of Pythagorean triples (a couple because they are infinitely many).
Step-by-step explanation:
Hope it helpful
2/5 is closer to 0
4/7 is closer to 1
the fraction would be 34/35 and is closer to 1 in decimal form it's about .97
50 might be the answer because 12÷6=2 so I just multiplied 15×2 and that equaled my answer, 50
I think that product means to multiply so if this is true than the answer would be:
5/8 × 2/3 = 10/24
Simplified to:
5/12
Answer:
Increased by 5%
Step-by-step explanation:
Let at the beginning the student's score be
points.
At first, it increased by 40%. So, the new score is

Then it decreased by 25%, so the new score is

At the beginning of a month the score was
and at the end of that month the score was
. Since
the score increased by
