Two ways:

=

and 1/4 = 25%
Another way.
300 = n% of 1200
Problem - we can't move n% back two place to change it to a decimal since we don't know what n is. Solution - move the decimal back on the 1200 two places because since of means x, it doesn't matter. Sample .45 x 32 = 45 x .32 Notice that the decimal can be place on either number and it results in the same answer.
So 300 = 12n (1200 moved back 2 places)
now divide by 12
<u>300</u> = <u>12n
</u>12 12 and once again n=25(%)<u>

The area of the collector panel is (its length) x (its width).
You know the long dimension ... it's 12 feet.
You need to find the short dimension.
The short dimension is the hypotenuse of the right triangle at the end of
the whole setup ,,, the triangle colored black.
In that right triangle, the leg standing up is 5-ft, and the acute angle
that's down on the roof is 54° degrees. Can you find the length of
the hypotenuse with this much information ?
How about . . . . . <u>sin(54°) = 5 / hypotenuse</u><u> ?</u>
(This is the big breakthrough. From here, the answer
practically falls into your lap.)
Multiply each side by 'hypotenuse' : sin(54°) x (hypotenuse) = 5
Divide each side by sin(54°) : Hypotenuse = 5 / sin(54°)
And there it is.
Area of the collector = (12-ft) x [ 5-ft / sin(54°) ]
That's (60 square feet) / sin(54°) = <em>74.164 square feet</em> (rounded)
Answer:
It would be losing 300.
Step-by-step explanation:
The opposite of gaining is losing the integer would be -300
The answer is 1, I would explain it but it’s a lot to type onto here.
Answer:
The length of the rectangle is 29 cm.
