Answer:
x=1,
y=1/2
Step-by-step explanation:
4x-8y=0
so 4x=8y
x=2y
5x+2y=6
because x=2y
so:
5x+x=6
6x=6
x=1;
then
x=2y
1=2y
y=1/2
Answer:
33
Step-by-step explanation:
3*4*2.75=33
A rectangular prism is a polyhedron with six rectangular faces. To fully define a rectangular prism, one must know its length, width and height. The volume of a rectangular prism is expressed as the product of its dimensions - length, width and height. To calculate for its width, we use the volume formula.
V = l x w x h
From the given, we have:
l = 3w
h = 2 + w
V = 135 ft^3
Substituting the given expressions,
135 ft^3 = 3w (w) (2+w)
135 ft^3 = 6w^2 + 3w^3
Solving for w, we obtain the following values:
w1= 3
w2 = 2.5 + 2.96i
w3 = 2.5 - 22.96i
Since width should not have a negative value, the value of w should be 3 ft.
Answer:
121π
Step-by-step explanation:
The formula for a circle is πr^2. But if given a diameter instead of radius, you simply divide by 2 because radius is half of a diameter.
Radius of this circle is 11 because you divide 22 by 2.
Then you follow the formula. 11^2=121.
