When you divide a whole number by a decimal less than 1, the quotient is greater than the whole number.why?

One way to understand division is to look at it as repeated
subtraction. When you "divide by" a divisor number, you're
asking "how many times can I subtract this divisor from the
dividend, before the dividend is all used up ?".

Well, if the divisor is ' 1 ', then you're taking ' 1 ' away from the
dividend each time, and the number of times will be exactly
the same as the dividend.

If the divisor is more than ' 1 ', then you subtract more than ' 1 '
from the dividend each time, and the number of times you can
do that is less than the dividend itself.

If the divisor is less than ' 1 ', then you only take away a piece of
' 1 ' each time. You can do that more times than the number in
the dividend, because you only take away a piece each time.

Which fraction does not belong with the other three explain 1/12 2/12 3/12 or 4/12

MakcuM [25]

1/12 does not belong with the other three fractions.

2/12, 3/12, and 4/12 can all be simplified to 1/6, 1/4/, and 1/3. However, 1/12 can't be simplified.

Please help me! I'm spending 50 points on this question and my last two questions never even got answered!

Answer:

Step-by-step explanation:

Domain is only affected if certain values can make the result something that either doesn't make sense or is an error. In your situation, it wants you to find the domain of f/g, which is a fraction. The only rule we have for fractions regarding domain is that we simply can't divide by zero, to find the domain for any fraction with variables in the denominator, what I do is take the denominator, set it equal to 0, and solve for x.

So, if we're taking f/g, we have:

$\frac{3x^2 + x^4 + 2}{4x - 3}$

4x - 3 makes up our denominator, the bottom part of the fraction. So

4x - 3 = 0

4x = 3

x = 3/4

So the denominator is equal to zero when x is equal to 3/4. This would produce an error in any calculator because you can't divide by zero. The domain here is all real numbers except for 3/4.

(For future problems, the only thing to look out for is if your numerator, the top part of the fraction, factors into something that cancels with the bottom. In that case, it wouldn't affect domain because you aren't actually dividing by anything. For example:

$\frac{x^2 - 4}{x-2}$

If we factor the top, we see that x^2 - 4 = (x - 2)(x + 2). In this case, we have (x - 2) in both the top and bottom of the fraction, so it cancels out, and from there nothing else is restricting our domain. It would be all real numbers in a case like that.)

PLEASE ANSWER QUICKLY I WILL MARK BRAINIEST AND 70 POINT

kykrilka [37]

a) You are given the rate as 7.4m/min,

The equation would become d = 7.4t where d is the total distance and t would be the total number of minutes.

b) d would be a positive number because the diver is ascending, which means he is moving up towards the surface.

c) To find how long it took the diver, replace d with 41.36 ( how deep the diver was) and solve for t:

41.36 = 7.4t

To solve for t, divide both sides by 7.4:

t = 41.36 / 7.4

t = 5.59 minutes ( 5 minutes and 35 seconds)

What is the value of x? x=______

jekas [21]

Answer:

x = 39

Step-by-step explanation:

Let's recall that the interior angles of a triangle always add up to 180 degrees.

Upon saying that, we have:

102 + 39 + x = 180

x = 180 - 102 - 39

x = 39

The value of x is 39 degrees
