Find y of this shape.

Mathematics
1 answer:
Leni [432]4 years ago

as shown in figure LN = KN

triangle KLN is right angle triangle so using Pythagoras theorem

KL^2 = LN^2 + KN^2

KL^2 = LN^2 + LN^2 = 2LN^2

KL = √(2LN^2)

y = LN√2

now lets find value of LN

now LMN is also right angle triangle so using trigonometry

MN/LN = sin 30

putting value of MN=5 and sin 30 which is 1/2

5/LN = 1/2

LN = 5×2= 10

putting it back in our first equation

y = LN√2

y = 10√2

Cole said that 555 rounded to the nearest ten is 600. What's coles error?
ki77a [65]
Cole's mistake was that he rounded 555 to the nearest hundred instead of the nearest ten. He should've rounded it to 560 because the tens place is the second number, not the first one.

How many ways are there to select five unordered elements from a set with three elements when repetition is allowed?
Zolol [24]

The number of ways or permutations to select five unordered elements from a set with three elements when repetition is allowed is 243.

According to the given question.

The total number of elements, n = 3

The number of elements to be selected at a time when repetition is  allowed, r = 5

Since, we know that " the number of ways or permutations of n things taken r all at a time, when repetition of things are allowed, is n^{r}.

Therefore,

The number of ways or permutations to select five unordered elements from a set with three elements when repetition is allowed

= 3^{5}

= 243

Hence, the number of ways or permutations to select five unordered elements from a set with three elements when repetition is allowed is 243.
