Answer:
lets start with the division
10/10
1
3+2 . 1 - 1
5 . 1 - 1
5. 1 = 5
5 - 1 = 4
Step-by-step explanation:
The volume of a rectangular prism is equal to length*width*height. In this case, we have V = 243 and H = 3.
243 = LW(3), so LW = 81, where L & W are whole numbers greater than 1. There are only 3 possible pairs of values for this: 27*3, 9*9, and 3*27 (we cannot use 1*81 or 81*1, since we need dimensions > 1).
Part A. This could be true if Length = 9 in and Width = 9 in, as 9*9 = 81.
Part B. The claim could be false if Length = 27 in and Width = 3 in, as 27*3 = 81, but 27 is not equal to 3.
*Note that the width cannot be longer than the length.
Answer:
(x)^2+ (y+2)^2 = 49
Step-by-step explanation:
The standard form of a circle is
(x-h)^2+ (y-k)^2 = r^2 where (h,k) is the center and r is the radius
(x-0)^2+ (y--2)^2 = 7^2
(x)^2+ (y+2)^2 = 49
this is just a example

Answer:
5.0 days
Step-by-step explanation:
From the question given above, the following data were obtained:
Initial mass (N₀) = 46 g
Constant (K) = 0.1374 /day
Half life (t₁/₂) =?
The half life (t₁/₂) is related to the decay constant according to the following equation:
t₁/₂ = 0.693 / K
With the above equation, we can obtain the half-life of the substance as follow:
Constant (K) = 0.1374 /day
Half life (t₁/₂) =?
t₁/₂ = 0.693 / K
t₁/₂ = 0.693 / 0.1374
t₁/₂ = 5.04 ≈ 5.0 days
Thus, the half-life of the substance is 5.0 days
2/9 = 14/n
14÷2/9 = 14/n÷14
63 = n
So, n=63
