Answer: [tex]9.38\times10^{33}[/tex]
Step-by-step explanation:
Given: Molecules in a liter of water = [tex]3.35\cdot10^{25}[/tex]
A certain river discharges about [tex]2.8\cdot10^8[/tex] liter of water every second.
Molecules in river = [tex]3.35\cdot10^{25}\times2.8\cdot10^8[/tex]
[tex]=3.35\cdot2.8\cdot10^{25}\cdot10^8\\\\= 9.38\times10^{25+8}\ \ \ \ [a^m\cdot a^n=a^{m+n}]\\\\= 9.38\times10^{33}[/tex]
Hence, there are [tex]9.38\times10^{33}[/tex] does the molecules in river per second.

Michael buys a car and agrees to pay $1,500 up front and $450 month for the next 2 years. Which shows the total amount,y, in dollars that will be paid at the end of x months?
Answer:
Total cost= $12,300
Step-by-step explanation:
Giving the following information:
Fixed cost= $1,500
Monthly cost= $450
To calculate the total cost, we need to use the following formula:
Total cost= fixed cost + unitary variable cost*x
x= number of units
For 2 years:
Total cost= 1,500 + 450*24
Total cost= $12,300

Why don’t we see the ground coming towards us ?
Answer:
Why don't we see the ground coming toward us?
Step-by-step explanation:
Why don't we see the ground coming toward us? We have less gravitational force than the earth. ... It has a lot of mass, so it feels the earth's gravitational force less than smaller objects do. It has more mass than the earth, so it stays in one place while the earth orbits it.

Answer:
[tex]m^{4\\}[/tex]+[tex]m^{2}[/tex][tex]n^{2}[/tex]+[tex]n^{4}[/tex]
Step-by-step explanation:
If you're distributing each value, I would recommend you to use the lattice method so that you can work on it faster. Make sure to add the exponents instead of multiplying to have an accurate answer. Once your done then cross out the ones that would subtract to 0 which would leave you with [tex]m^{4\\}[/tex]+[tex]m^{2}[/tex][tex]n^{2}[/tex]+[tex]n^{4}[/tex] as your final answer if you did it properly.
Solve this equation
2 (c+8) = -12
Answer:
C= -14
Step-by-step explanation:
2(c+8)= -12 > divide both sides by 2
C+8= -6 > move c by itself
C= -6-8 > then subtract -6 and -8 and you will get -14

To divide 1.95 + 0.005, you will need to move the decimal in the divisor and the
dividend to the ...
Left one place
Left two places
Right two places
Right three places
I'm assuming the goal of this style of division is to divide by whole numbers instead of decimal numbers. In that case, you would need to move the decimal in the divisor and the dividend three places to the right.

Answer:
7/8 because there are 4 dashes and the point is right in the middle of them, making it so the denominator is 8, you figure out the 7 because 8/8 would be 1, and the point is right before 1 so it has to be 7/8

I'm also on Edge and am on this same question. Credit to the other person for also saying 7/8 and being right :D
During the summer, 1.3% of the water in the kiddie pool evaporates every day. If the kiddie pool holds 8,000 gallons of water and is not
refilled for 10 days, how many gallons of water will be in the pool? Round your answer to the nearest gallon enter the amount
Answer:
7019 gallonsStep-by-step explanation:
Initial volume of water = 8000 galDaily reduction = 1.3% Time = 10 daysRequired equation:
8000*(1- 0.013)^10 =8000*0.987^10 =7018.7781 ≈ 7019 rounded to the nearest gallonSolve -2(x-5) + 3x = 2(x+3) + 17 *
Answer:
x=-13
Step-by-step explanation:
Hope this helped :)
Answer:
x = -13
Step-by-step explanation:
-2x + 10 + 3x = 2x + 6 + 17
x + 10 = 2x + 6 + 17
x + 10 = 2x + 23
10 = 2x + 23 - x
10 = x + 23
10 - 23 = x
-13 = x
x = -13

Your restaurant bill is $42.16. You want to leave a 20% tip. What is your best
estimate of a 20% tip?
Your answer
Answer:
$8.40
Step-by-step explanation:
Since this is an estimate, you need to do it in your head. The way I did it was I divided 40 by 5 since 20% is one fifth of 100%, then I divided 2 by 5 and added them together which equaled 8.40.
Answer:
About $8
Step-by-step explanation:
Move decimal point one place to the left (making $4.20), then double that answer (making $8.40). You said estimate so I rounded down to $8 but a more precise answer would be $8.40.
Hope this helps :).

how can i solve -4.6x = -11.04
Answer:
The last one
Step-by-step explanation:
Answer:
D, Divide both sides by -4.6
Step-by-step explanation:
You want to get the x and the regular integers on separate sides of the equals sign, so you divide the -4.6 to get the x on its own side of the equals sign. That's the first step to solving the equation.
