4 i think when its not simplified.
Answer:
I dont really think this is it but i think its 20
Step-by-step explanation:
60 divided by 3 is 20
Answer:
The correct answer is option 1. cubic units.
Step-by-step explanation:
The formula for the volume, V of a right angled cone is given as:
Where,
is the radius of the circular base of the cone.
is the height of the cone.
We are given that height is twice of the radius of its base.
Let the radius of base = units
Now, As per the question statement,
The height of cone= units
Putting the values of in equation (1) to find the volume:
Hence, the correct answer is option 1. cubic units.
Think back to the definition of absolute value:
• If <em>x</em> ≥ 0, then |<em>x</em>| = <em>x</em>.
• If <em>x</em> < 0, then |<em>x</em>| = -<em>x</em>.
In other words, the absolute value always returns a positive number. So if <em>x</em> is positive, leave it alone; but if it's negative, then you have to negate it to get a positive number back.
This means that you cannot simply reduce |<em>x</em> - <em>y </em>| to <em>x</em> - <em>y</em> because you need to consider the possibility that <em>x</em> - <em>y</em> may be negative, in which case |<em>x</em> - <em>y</em> | would reduce to -(<em>x</em> - <em>y</em>) = <em>y</em> - <em>x</em>.
In this case,
|4√2 - 6| = -(4√2 - 6) = 6 - 4√2
because 4√2 < 6, which you can determine by comparing both of these numbers as square roots:
4√2 = √16 √2 = √32
6 = √36
and √32 < √36 because 32 < 36.
Similarly,
|2√10 - 6| = 2√10 - 6
because
2√10 = √4 √10 = √40
6 = √36
So ultimately,
|4√2 - 6| + |2√10 - 6| = (6 - 4√2) + (2√10 - 6) = 2√10 - 4√2
Answer:
y = 6
Step-by-step explanation:
3y/2 - 1 = 8
3y/2 = 8 + 1
3y/2 = 9
3y = 9 × 2
3y = 18
y = 18/3
y = 6
