Answer:
The area of one side of the tank is
Step-by-step explanation:
A cube is a regular Polyhedron limited by six equal squares. It is also known as the regular hexahedron, or simply hexahedron.
The cube is a ortohedron, that is, it has its six faces straight and perpendicular to each other. In addition to being their rectangle faces, they are also square.
It has the following properties:
*Number of faces: 6
*Number of vertices: 6
*Number of edges: 12
*Number of edges from one vertex: 3
Being the length of the edge of the cube, then its Volume (V) is expressed by the formula: Being a the length of the edge of the cube
A fish tank is the shape of a cube. Its volume is , to calculate the are of one side of the tank, we know that each faces has the form of a square of area .
To calculate the value of a.
Then the area of square is
Substituting the value of a
Answer: B. exponential decay
Step-by-step explanation:
From the given table, we can observe that y is decreasing as x is increasing.
So it must be a decay function.
Also it can not models a linear relationship, since the rate of change is not constant throughout the table.
then it must be exponential decay function.
An exponential decay is represented by
. where x is the time period, A is the initial amount and r is the rate of decay

Answer:
<h3>The answer is option D</h3>
Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
y = 2x + 4
comparing with the above equation for a line
The slope / m = 2
Since the lines are parallel their slope are also the same
Slope of parallel line = 2
So we have
The equation of the line using point
( 3 , -2) and slope 2 is
y + 2 = 2( x - 3)
y + 2 = 2x - 6
y = 2x - 6 - 2
We have the final answer as
<h3>y = 2x - 8</h3>

Answer:
Each strip is 117.6 cm
Step-by-step explanation:
I created a proportion of hearts to others. On strip A there is 1 heart to 2 others and B there is 1 heart to 3 others. I added them and got a proportion of 2 hearts to 5 others for both. With a total of 56 hearts, I set up a proportion to determine the total stickers
2/5=56/x
When I cross multiply, I get 2x=280 and x=140
so for the 56 total hearts, I have 140 others. I added those to get the total stickers and got 196. I multiplied that by 1.2cm and got 235.2 cm for both. Since both are the same size, just divide that by 2 and get 117.6 cm each.
