Answer:
508.68 cubic inches
Step-by-step explanation:
Formula for volume of a cylinder=
Therefore, Volume of cylinder = 3.14 * 81 * 2= 508.68 cubic inches
Answer:
It is not a Right Angled Triangle.
Step-by-step explanation:
A right angled triangle is a triangle whose sides satisfy the following equality.
Lets say A triangle has sides a, b and c. Where c is the longest side.
Then,
Lets substitute the values to the above equation to see whether the triangle we are given satisfies the above equality,
= =
Therefore, ≠[tex]18^{2}
So it is not a Right Angled Triangle.
Group and factor out the linear coefient
(3x^2+4x)+?=1+????
3(x^2+4/3x)+?=1+????
4/3 divided by 2 is 2/3
2/3 squared is 4/9
add negative and negative inside
3(x^2+4/3x+4/9-4/9)+?=1+????
factor perfect square
3((x+2/3)^2-4/9)+?=1+????
distribute
3(x+2/3)^2-4/3+?=1+????
add 4/3 to both sides
3(x+2/3)^2+?=7/3+????
minus? from both sides
3(x+2/3)^2=7/3+????-?
dunno what missing number is, maybe
hmm
4/9 times 3=4/3
the missing number is 4/3
Answer:
39
Work:
(x+5)/2=22
We will reverse this equation.
We will start by moving the 2 through inverse operations.
22x2=44
Now we have the equation
x+5=44
We will subtract 5
44-5=39
x=39
the unknown variable equals 39
