Answer: H = 20
Step-by-step explanation:
To find the hypotenuse , we will use Pythagoras theorem, which states that
The square of the hypotenuse = the square of the adjacent + the square of the opposite.
Since , we are dealing with isosceles right triangle , this means that :
both the adjacent and the opposite are equal, using the formula to find the hypotenuse , let H represent the hypotenuse , then
= 
+
= 400 + 400
= 800
Take the square root of both sides
H = 
can be written as 
x
Therefore :
H = x
H = 20x
H = 20
Add up the same sides of both equations to eliminate <em>x</em> :
(<em>x</em> - 2<em>y</em>) + (-<em>x</em> + 3<em>y</em>) = 8 + (-5)
(<em>x</em> - <em>x</em>) + (-2<em>y</em> + 3<em>y</em>) = 8 - 5
<em>y</em> = 3
Then
<em>x</em> - 2<em>y</em> = <em>x</em> - 6 = 8 → <em>x</em> = 14
Answer:
2,160 Hours
Step-by-step explanation:
Ok so usual i would split $540 in half so a number multiplied by two would end up as 540, and i got 270. So since each week we know Phillip earned $270 and $11.25 a hour, we can divide 270 by 11.25, which gives us $24, so that means h = 24, but on week 2 it says Phillip worked 8 hours more on week 2, so that gives us a equation of 8 x 11.25, which comes out to 90, so now we can move on to our final equation, 90 x 24, which equals 2160. Im so sorry if this is wrong
Answer:
-1/32
Step-by-step explanation:
we have
Remember that
The exponent "product rule" tells us that, when multiplying two powers that have the same base, you can add the exponents
so
