Answer:
Step-by-step explanation:
Question :
Given:
varies directly with
when
To find value of when
Solution:
From the given data we have:
∝
Thus, we have:
where is the constant of proportionality.
<em>We can find the value of by plugging in the given values.</em>
when
Dividing both sides by 2.
∴
So, the equation to find when will be:
Thus, when (Answer)
Answer:
2. h = 3.5
Step-by-step explanation:
1. The equation <em>-4h = -14</em> means that -4 times h equals -14
2. -4h = 14
h = -14/-4
h = 7/2 = 3.5
Answer
8
Step-by-step explanation:
5+12=17 and 17-9=8
Sqrt 128 to get 11.31
You can do Pythagorean theorem. One side is 8, and since this is a square, the other side is 8. 8 squared plus 8 squared is 128, then square root it. Treat it like a right triangle
Answer:
The correct answer is option B
Step-by-step explanation:
The general form of inverse variation between the variables x and y is as following:
where c is constant
option A : y = x/12 ⇒ x = 12y (wrong option)
option B : y = 12/x ⇒ y * x = 12 (correct option) and c will be equal 12
option C : y = x + 12 ⇒ not similar to the general form (wrong option)
option D : y = 12x (wrong option)
So, the correct option is B
