Answer:
S = 8
Each side of a face is 8 units.
Step-by-step explanation:
The surface area of the cube is 384 units.
One face of the cube has an area of s^2
A cube has 6 faces
6s^2 = 384 Divide by 6
s^2 = 384 / 6
s^2 = 64 Take the square root of both sides
sqrt(s^2) = sqrt(64)
s = 8
I didn't round by the answer would be 115.575042 miles per second.
The height (h) of the water in cm for d days is given by the equation h(d) = -0.9d + 1200
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let h represent the height of the swimming pool after d days, the water evaporates 0.9 cm in height each day. If the pool water starts at 1200 cm hence:
h(d) = -0.9d + 1200
The height (h) of the water in cm for d days is given by the equation h(d) = -0.9d + 1200

Answer:
B.
Step-by-step explanation:
On our left, we have 7 "x's" and 7 "1's". Let this be 7x + 7.
On our right, we have 5 "x's" and 16 "1's". Let this be 5x + 16.
We would have the equation:
Solve for x. Collect like terms.
Divide both sides by 2
