Answer:
C = 75.
Step-by-step explanation:
Set up our eq:
600 x
___ = ___
80 100
Cross multiply:
6 x 10 = 60 (add two zero's) = 6000
now, 80 * x. 80x
Now we divide:
6000
_____
80
C = 75
Answer:
A) 3(x+6)
Step-by-step explanation:
Given,
The area of the model = (6x+18)
If the dimensions of the model are, x unit × y unit,
Then,
xy = 6x + 18
If x = 3, y = x + 6
3(x+6) = 3x + 18 ( by distributive property )
∴ Option A doesn't represent the dimensions of the model,
If x = 6, y = x + 3
6(x+3) = 6x + 18
∴ Option B represents the dimensions of the model,
If x = 0.5, y = 12x+36
0.5(12x+36) = 6x + 18
∴ Option C represents the dimensions of the model,
If x = 0.25, y = 24x + 72
0.25(24x+72) = 6x+18
∴ Option D represents the dimensions of the model,
I just got free points. Thank you.
Answer:
i) superset (A)
ii) 0.577 (A)
Step-by-step explanation:
i) A subset is a set which has all its elements contained in another set.
For two sets A and B, if each element of set A is an element of set B, then A is a subset of B.
A superset is a set that houses another set. So if set A is a subset of set B, then B is a superset of A.
Proper subset
For a set (A) to be a proper subset of another (B) every element of A would be in B but there exists at least one element in B that is not in A.
An Empty Set (or Null Set) doesn't have aren't any elements in it. It is empty.
Since every element of the superset is in the superset. Therefore, A superset contains all the subset of superset.
ii) Square root of 1/3 = √⅓
= ± √⅓ = +√⅓ or -√⅓
+√⅓ = +(√1/√3) = +(1/√3)
+√⅓ = +(1/1.7321)
+√⅓ = +0.577
Therefore Positive square root of 1/3 is 0.577 (A)
<span>Simplifying
1.5x + -3y = 6
Solving
1.5x + -3y = 6
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3y' to each side of the equation.
1.5x + -3y + 3y = 6 + 3y
Combine like terms: -3y + 3y = 0
1.5x + 0 = 6 + 3y
1.5x = 6 + 3y
Divide each side by '1.5'.
x = 4 + 2y
Simplifying
x = 4 + 2y</span>
