Answer:
X=63
Y=27
Step-by-step explanation:
Okay so, 117 and x form a straight (180 degree) angle.
that means that 117+x=180
solving that, x=63
now we also know that x+y=90 ( a right angle)
so plugging in x, 63+y=90
meaning that y=27
Hope this helps, and have a wonderful day! =)
No it doesn't form a proportion
Answer:
The approximate number of gallons of water that flow over the waterfall in 1 day is:
Step-by-step explanation:
To obtain the answer to the question, you must multiply the number gallons of water flow over a waterfall each second (6.5 x 10^5 gal/s) by the number of seconds in a day (8.6 x 10^4 s), as I show you below:
- Gallons of water that flow over the waterfall in 1 day = Number of gallons * Number of seconds in a day.
- Gallons of water that flow over the waterfall in 1 day = 6.5 x 10^5 gal/<u>s</u> * 8.6 x 10^4 <u>s</u>
Now, we must cancel the seconds, then:
- <u>Gallons of water that flow over the waterfall in 1 day = 5.59 x 10^10 gallons</u>
How you can see, <em>once you have multiplied these two values, the answer is the same to the option A</em>.
