In miles 365 million miles or 365,000,000
in km, 588 million km or 588,000,000
so
scientific notation=(number less than 10 and greater than or equal to 1) times 10^n
so
we need to move the decimal point 8 spaces to the left
to compensiate for that, we multiply by 10⁸ which will move it 8 to the right
so
365,000,000 mi=3.65 times 10⁸ mi
588,000,000 km=5.88 times 10⁸ km
those are the distances in scientific notation
Answer:
1
Step-by-step explanation:
Domain is the x-values
Range is the y-values
To identify the range, plug in the x-values they gave you into the equation to find its y-value
x = 3
y = 2x + 4 Plug in 3 for x
y = 2(3) + 4
y = 10
x = 5
y = 2x + 4 Plug in 5 for x
y = 2(5) + 4
y = 10 + 4
y = 14
x = 6
y = 2x + 4 Plug in 6 for x
y = 2(6) + 4
y = 16
x = 8
y = 2x + 4 Plug in 8 for x
y = 2(8) + 4
y = 20
The range is {10, 14, 16, 20}

Answer: 4 minutes</h3>
============================================================
Explanation:
Let's say that this tub is 72 gallons. I picked this number since 12*6 = 72. You can pick any number you want, but I picked this number so we end up with whole number results as shown below.
Tap X can fill the 72 gallon tub in 12 minutes. Its rate is 72/12 = 6 gallons per minute. Tap Y has a rate of 12 gallons per minute because 72/6 = 12.
Add the two unit rates: 6+12 = 18
If the two taps are opened at the same time, then they will work at a rate of 18 gallons per minute.
Let x be the number of minutes. The expression 18x represents how much of the tub is full after x minutes. Set this equal to the 72 we started with earlier and solve for x.
18x = 72
x = 72/18
x = 4
It will take 4 minutes if both taps are running at the same time.
