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>.
If you would like to know the simplified expression for 2 * (x - 5), you can find this using the following steps:
2 * (x - 5) = 2 * x - 2 * 5 = 2 * x - 10
The correct result would be <span>2 * x - 10.</span>
Answer:
(2v +7)(v -9)
Step-by-step explanation:
Factors of 2·(-63) = -126 that have a sum of -11 are 7 and -18, so we can rewrite the middle term to -18v+7v. Then we can factor by grouping.
2v^2 -18v +7v -63 = 2v(v -9) +7(v -9)
= (2v +7)(v -9)
Answer:
it would be 5
