Answer:

y = sqrt(5)

x = sqrt(10)

Step-by-step explanation:

y = sqrt(5)

Opposite angles are equal

x is the hypotenuse

x² = 5 + 5

x² = 10

x = sqrt(10)

<h3>Answers:</h3><h3>x = sqrt(10)</h3><h3>y = sqrt(5)</h3>

============================================

Explanation:

Naturally I start with x as that letter precedes y in the alphabet; however, it's easier to start with y because it is a leg of this triangle. We will then use the value of y to find x later.

For any 45-45-90 triangle, the two legs are the same length. So that's why we're able to quickly see that y = sqrt(5)

To get the hypotenuse, we multiply the leg length by sqrt(2). This trick only works for 45-45-90 triangles.

hypotenuse = leg*sqrt(2)

x = sqrt(5)*sqrt(2)

x = sqrt(5*2)

x = sqrt(10)

The rule I used is sqrt(a)*sqrt(b) = sqrt(a*b)

----------------

An alternate path is to use the pythagorean theorem to find x

a^2+b^2 = c^2

(sqrt(5))^2 + (sqrt(5))^2 = x^2

5 + 5 = x^2

10 = x^2

x^2 = 10

x = sqrt(10)

Answer:

1. 5040

2. 20

Step-by-step explanation:

1. using the formula for permutation

nPr=n!/(n-r)!

10P4 = 10!/(10-4)!

=10*9*8*7*6!/6!

then we are left with

=10*9*8*7

=5040

2.using the formula for combination

nCr=n!/(n-r)!r!

6C3=6!/(6-3)!3!

=6*5*4*3!/3!3!

=6*5*4/3*2*1

=20

You discover that you are over serving a dish because customers keep taking a third of it home. If the dish requires 4 ingredien
devlian [24]

Answer:

4 parts

Step-by-step explanation:

If the total number of parts is 12 and you want to reduce the dish to two-thirds its current size, the number of parts that will be reduced is (1 - 2/3) = 1/3

To reduce 1/3 of the 12 parts, you need to multiply 12 by 1/3 to know how many parts is that:

12 * 1/3 = 12/3 = 4

You need to subtract 4 parts. If you have 4 ingredients, you can remove 1 part of each, so each ingredient now will have 2 parts.
