Answer:
x=103 degrees
y=113 degrees

Explanation:
All the angles in a triangle add up to 180 degrees, so to find the measurement of angle x, we can use this equation and solve:

x=180-23-54
x=180-77
x=103

To find angle y, we need to understand that a straight line also has an angle of 180 degrees. This means we need to subtract the angle that is next to angle y from 180 to get angle y.

However, to find that angle that is next to angle y, we need to do the same thing we did above and find the angles of the triangle.

First, we find the angle next to x using this expression:

180-x
=180-103
=77

And now we find the measurement of the angle next to angle y:

180-77-36
=103-36
=67

And now we find angle y:

180-67
=113

Therefore, y=113 degrees

I hope this helps! Please comment if you have any questions.

Which number in the monomial 215x18y3z21 needs to be changed to make it a perfect cube?
hoa [83]
We need to remember that:
                   xyz = (x)(y)(z)
if x, y and z are perfect cubes, then xyz would also be a perfect cube

Also, 
                 (x^n)^m = x^(mn)
if it is a perfect cube, then it can be factored into the expression (x^n)^3, wherein n is a whole number.

All should be a perfect cube, given

215x^18(y^3)(z^21)

By writing the terms separately, we would see which one is to be changed. 

215 = 5*43, we see this is not a perfect cube, we could changed it to 6^3 or 216

x^18=(x^6)^3

y^3=y^3
z^21=(z^7)^3

The other terms are perfect cubes except for the first one. So the correct answer would be the last option, 215 should be changed.

Mold grows on bread and every day it doubles by the eighth day the entire bread is covered with mold when was half the bread cov
Brut [27]

Answer:

The mold will cover half the area as much are one day before it.

Step-by-step explanation:

Given:

Every day the mold on bread grows doubles

And by 8th day entire bread covered with it.

To Find:

When was half the bread covered by mold.

Solution:

It is said that area covered by mold doubles on each day

Total days taken to cover entire bread are 8

Let Area of bread be A

So Area covered (A) corresponds to 8 days with doubling.

So on previous day it should What ever area on 8th day/2

i.e A(8)/2

Similar on 6th day A(7)/2

So on 5ht day =A(6)/2 ,4th= A(5)/2,  on 3rd= A(4)/2, on 2nd=A(3)/2

On 1st =A(2)/2

So we required  Area= half of total.

<em>One day before the 8th day will be 7th day</em>

<em>on that day it will cover half are so that on next day will cover the double of the previous area consumed.</em>

zzz [600]

Answer:

1/8

Step-by-step explanation:

<u>Solving in steps:</u>

  • x(8x - 8y)⁻¹ + y(8y - 8x)⁻¹ =
  • x/8(x-y) +y/8*(-(x-y))
  • x/8(x-y) - y/8(x-y) =
  • (x -y)/8(x-y) =
  • 1/8

Answer is 1/8
