<h2>
The required "option B) xy = 12" is correct.</h2>
Step-by-step explanation:
Check the options:
A) 4x = 12
Dividing both sides by 4, we get
⇒ x = 3
4x = 12 is a linear equation in one variable x.
B) xy = 12
xy = 12 is a non-linear equation.
D) 3x - 6y = 12
Dividing both sides by 3, we get
⇒ x - 2y = 4
3x - 6y = 12 is a linear equation in two variables x and y.
Thus, the required "option B) xy = 12" is correct.
Answer:
d. 13 inches
Step-by-step explanation:
When we need to solve the side length and length of triangles, we need to remember one thing.
Coming to a right triangle, there are two short sides and one long side, and the two short sides need to add up to something less than the one long side.
Therefore, since we know our two short sides, add them :
7in. + 5in.
= 12in.
Looking at the answers, we can point out that d. is greater than 12 inches, therefore making it the correct answer.
Answer:
The closest measurement to the volume of hat is 84.82 in.³.
Step-by-step explanation:
Given:
The dimensions of hat are height(h) 9 inches and diameter(d) 6 inches.
Now, to find the volume of cone:
Putting the formula .
Radius(r) is not given, finding the radius:
Radius(r)=half of the diameter(d)
.
Then,
=
= ()
=
=
= in.³
So, the volume is 84.78 in.³ .
Therefore, the closest measurement to the volume of hat is 84.82 in.³.
Assuming the equations are:
<span>−4x+y=−6
8x−2y=14
The second equation can be rewritten (divide by -2) to
-4x+y=-7
This system has no solutions. If you would draw them as lines, they are two parallel lines that never intersect.</span>
