<span>The value of y when x=3 when the value of y varies directly with x^2, and y = 150 when x = 5 is 54. Since the value of y varies directly with x2, then: y = k * x^2, where k is constant. When y = 150 and x = 5, the value of constant is: 150 = k * 5^2. 150 = k * 25. k = 150/25. k = 6. Thus, when x = 3, the value of y will be: y = 6 * 3^2. y = 6 * 9. y = 54.</span>
Answer:
The approximate area is 35 square centimeters
Step-by-step explanation:
we know that
The cross section passing through the diagonal of opposite faces of the cube is a rectangle
so
the approximate area is equal to
where
b is the diagonal of a face
h is the length side of the cube
we have
substitute
Answer:
Its C
Step-by-step explanation:
Answer:
w = -1.5
Step-by-step explanation:
To solve for w in the question below;
3.4 w=−5.1
All we need to do is to divide both-side of the equation by 3.4
3.4 w/3.4 = −5.1/3.4
On the left-hand side of the equation, 3.4 at the numerator will cancel-out 3.4 at the denominator leaving us with just w, while on the right-hand side of the equation negative 5.1 will be divided by 3.4. That is
w = -5.1/3.4
w = -1.5
Answer:
160
