There is no way of solving that unless we are given more information. Are ABC and DBC supplementary angles? If so, then m<DBC equals 70.
Answer:
11.6 mi
Step-by-step explanation:
9.3^2+6.9^2 = 134.1
sqrt134.1 = approx 11.6
Answer:
I think the answer is $41.66
Step-by-step explanation:
I found how many months it was, which was 216.
Divided 150,000 by 216, which was 694.44.
And lastly, I multiplied 694.44 by 0.06(the same as 6%) and that gave me 41.66.
Answer:
The constant of proportionality k = 12
Hence, option A is true.
Step-by-step explanation:
We know that when 'y' varies directly with 'x', we get
y ∝ x
y = kx
Where 'k' is called the constant of proportionality.
In our case,
The given equation is
y = 12x
comparing with the equation y = kx, we can say
k = 12 which is the constant of proportionality.
Therefore, we conclude that:
The constant of proportionality k = 12
Hence, option A is true.
To find whether the volume would be doubled when the radius is,we can find the volume of the two balloons.
The formula of a sphere is:

Let's take 丌 as 3.14
The volume of the balloon with 4cm radius:

The volume of the balloon with 8cm radius:

As we can see,
267.94668 × 2 = 535.89 ≠2145.56
Thus,she wouldn't discover that the volume is twice as big when the radius is doubled.
Hope it helps!
