Answer:

  30.67 feet

Step-by-step explanation:

A proportion is often useful for solving scale drawing problems.

  actual size : drawing size = (room length) : (23 in) = (2 ft) : (1.5 in)

Multiplying by 23 in gives ...

  room length = (2 ft)(23 in)/(1.5 in) = 46/1.5 ft = 30 2/3 ft

  room length ≈ 30.67 ft.

<h2>Answer: ∅</h2>

Step-by-step explanation: When solving by completing the square,

we cannot have a coefficient on the squared term.

So first divide both sides by 4 to get x² + 4x + 25/4 = 0.

Now subtract 25/4 from both sides and leave a space.

So we have x² + 4x ____ = -25/4 ____.

The number that goes in that space is the number needed

to create a perfect square trinomial on the left side.

The question is, what is that number?

Well it comes from a formula.

The number that goes in that space comes from

half the coefficient of the middle term squared.

So that's half of 4 squared or 2 squared which is 4.

So we add 4 to both sides.

On the left, we will get a binomial squared

which will use x and half the coefficient of the middle term.

So we have (x + 2)².

On the right, -25/4 + 16/4 is -9/4.

So we have (x + 2)² = -9/4.

Notice that when take the square root of both sides,

we have the square root of a negative which is illegal.

So we say our answer is ∅.

A cylindrical vase has a diameter of 6 inches. At the bottom of the vase, there are 9 marbles, each of diameter 2 inches. The va
nadezda [96]
The volume of water in the vase is the difference of volume of cylinder and that of the marbles. 
            Vcylinder = πr²h = π(6 in)²(12 in) = 432π in³
            Vmarbles = 9(4πr³/3) = 9(4π(3 in)³/3) = 324 π in³
The difference of the volumes is 108π in³.

What is the solution to the following system? <br> 2y +x=4<br> y=-0.5x + 2
icang [17]
1) Input Y.
2(0.5x + 2) + x = 4

2) Distribute and combine like terms
= 2x + 4 = 4

3) Subtract 4 from both sides
2x = 0

4) Divide.
2x/2 = 0/2

x = 2

The ratio is 4:3:1
let the ratio be 4x:3x:x
according to the question,4x+3x+x=40
8x=40
x=5
therefore amount of gravel=x*4=5*4=20m^{3}
amount of sand=5*3=15m^{3}
amount of cement=5*1=5m^{3}
