As we know,
So, we can infer that :
Now, let's calculate the mass of gases in each case :
<h3>Case A : Hydrogen ~</h3>
or
<h3>Case B : Helium ~ </h3>
or
<h3>Case C : Nitrogen ~ </h3>
or
So, the arrangement of masses from least to greatest is :
- (1.) Hydrogen < (2.) Helium < (3.) Nitrogen
<u>Answer</u>
C. 4 + 6
D. 3.15151515.. + 4.6
E. √64 × √25
<u>Explanation</u>
A rational number is a number that can be expressed as a quotient or a fraction. That is it can be written as a/b.
π×6 = 6π ⇒ can not be written as a rational number.
√3 + √5 ⇒ the sum of two irrational numbers can not be rational.
4 + 6 = 10. Ten is a rational number. it can be written as 10/1
3.15151515.. + 4.6 = 104/33 + 23/5
= 1279/165
√64 × √25 = 8×5=40 This can be written as 40/1
Answer:
Factored form...
Step-by-step explanation:
Foil out (x-4)(x+2)=16
First: x*x=
Outer: 2*x=2x
Inner: -4*x = -4x
Last: -4*2 = -8
Combine them all:
Simplify:
What multiplies together to make -24 but adds together to make -2?
Lets list the factors of -24 to decide:
1 x -24
2 x -12
3 x -8
4 x -6
-6+4 = -2
Therefore...
Answer:
Solution 1: 1+1
Solution 2: 1-
Step-by-step explanation:
x^2-2=2x
x^2-2x-2=0
Use quadratic equation.
(-b+-)/2a
(2+-)/2
(2+-)/2
(2+-)/2
Solution 1: (2+2)/2=1+1
Solution 2: 1-
It is given that the cost of renting a car is a flat rate of $45 per day plus $0.25 for each mile you drive. So cost as a function of distance traveled is
.
When ,
So for $75, the driver can drive
