35/8 = (4 * 8 = 32) and 3 left over so answer is 4 3/8
Answer:
Step-by-step explanation:
Well, what happens when you multiply a number by 10? 1*10 is just 10 of course, 2*10 is 20, 3*10 is 30 and so on. This pattern continues, so if you multiply anything by 10 you take whatever it was and move everything to the next highest "place. so for 2, which starts in the ones place you move it to the tens place. For whole numbers you can think of it as just adding a 0 to the end.
Anyway, for this it's asking what gets multiplied by 10 to get 25,960. Well, since it's a whole number realize that whatever this number was times 10 got a 0 added to it. so just take that last 0 away. 2,596
Another method is dividing by 10, which just does the opposite of multiplying by 10.
Answer:

Answer:
B = ±X
Step-by-step explanation:
A^2 + B^2 = A^2 + X^2
Subtract A^2 from each side
A^2-A^2 + B^2 = A^2-A^2 + X^2
B^2 = X^2
Take the square root of each side
sqrt(B^2) = ±sqrt(X^2)
B = ±X
Answer:
The rocket hits the gorund after approximately 10.71 seconds.
Step-by-step explanation:
The height of the rocket <em>y</em> in feet <em>x</em> seconds after launch is given by the equation:
And we want to find the time in which the rocket will hit the ground.
When it hits the ground, its height above ground will be 0. Hence, we can let <em>y</em> = 0 and solve for <em>x: </em>
<em /><em />
We can use the quadratic formula:
In this case, <em>a</em> = -16, <em>b</em> = 165, and <em>c </em>= 69.
Substitute:
Evaluate:
Hence, our solutions are:
Since time cannot be negative, we can ignore the first answer.
So, the rocket hits the gorund after approximately 10.71 seconds.
