To find the volume we use an equation:

volume = length x width x height

Since this shape is a cube, you only need to know one side to find the volume since all of the sides are equal.

So all you need to find the volume is to multiply 4(1/2) which I am going to simplify to 4.5, is plug it into the equation.

volume = 4.5 x 4.5 x 4.5

Which will get you an answer of 91.125 inches cubed

91.125in^{3}

Hope this helps :)

Find A, B, and C <br> Help ASAP!<br> {10 points up}
Rama09 [41]

so we have a 60-30-90 triangle (top one)

so since we know 6 is x (the side on the right angle and 60 degrees)

b is 2x or 2(6) = 12

a is x√3 = 6√3


for C I need to use a 45 45 90 triangle

Since b is 12 and its x√2  to find x we should write it as

x√2 = 12

√2     √2  divide by √2

x = 12/√2  but we must rationalize the denominator

12/√2  times √2/√2  = 12√2/2 and that's c

Me ayudan con esa ecuacion por sustitucion con la comprobacion pliss
attashe74 [19]
<span>1/2x+3y/4=5 => (1/2)x + (3/4)y = 5

1/5x+3y/2=2  => (1/5)x + (3/2)y = 2

Eliminate the fractional coefficients:  Mult. the first equation by 4 and mult. the second equation by 10:


2x + 15y = 20     

</span><span>Multiply the 1st equation by -1:

-</span>2x - 3y = -20
2x + 15y = 20 
-------------------
       12y = 0, so y = 0.  Then the first equation becomes  2x + 3(0) = 20, or
                                     x=10.

Solution is (10,0).

Will mark brainliest please help Debbie notices that the amount owed on her monthly heating bill varies inversely with the avera
Alekssandra [29.7K]

Answer:

The bill is $1837.5

Step-by-step explanation:

Given

B = Bills

T = Temperature

B\ \alpha\ \frac{1}{T} --- The variation

T = 35; when B = 210

Required

Find B when T = 40

B\ \alpha\ \frac{1}{T}

Express as an equation

B = \frac{k}{T}

Make k the subject

k = BT

<em>T = 35; when B = 210</em>

k = 35 * 210

k = 7350

When T = 40, we have:

k = BT

7350 = B * 40

Make B the subject

B = \frac{7350}{4}

B = 1837.5
