Answer:
A - 17.576
Step-by-step explanation:
All we have to do is replace s with 2.6!
V = s^3
v = 2.6^2
v = (2.6)(2.6)(2.6)
v = 6.76 * 2.6
v = 17.576
So, the volume of the cube is 17.576 feet! :)
Y=2/3 times x/1-3
=y=2x/3-3
y=2/3x-3
Answer:
The dimensions of the yard are W=20ft and L=40ft.
Step-by-step explanation:
Let be:
W: width of the yard.
L:length.
Now, we can write the equation of that relates length and width:
(Equation #1)
The area of the yard can be expressed as (using equation #1 into #2):
(Equation #2)
Since the Area of the yard is
, then equation #2 turns into:

Now, we rearrange this equation:

We can divide the equation by 5 :

We need to find the solution for this quadratic. Let's find the factors of 160 that multiplied yields -160 and added yields -12. Let's choose -20 and 8, since
and
. The equation factorised looks like this:

Therefore the possible solutions are W=20 and W=-8. We discard W=-8 since width must be a positive number. To find the length, we substitute the value of W in equation #1:

Therefore, the dimensions of the yard are W=20ft and L=40ft.
251,782.
Just add 3*16,454 to the original number.
3/6 because there are 6 sides and there are 3 numbers that you want to roll. They are even numbers so if you want to roll half of the numbers but not the other half well you have 3/6
