Cantwell Associates, a real estate developer, is planning to build a new apartment complex consisting of one-bedroom units, two-

bedroom townhouses, and three-bedroom townhouses. A total of 216 units is planned. The total number of two- and three-bedroom townhouses will equal the number of one-bedroom units. If the number of one-bedroom units will be 3 times the number of three-bedroom townhouses, find how many units of each type will be in the complex. one-bedroom units units two-bedroom townhouses units three-bedroom townhouses units

Answer:

108 one-bedroom units

72 two-bedroom units

36 three-bedroom units

Step-by-step explanation:

<em>Let x, y, z the number of one-bedroom, two-bedroom and three-bedroom units respectively.</em> Then  

1) x+y+z = 216

2)     y+z = x

3)         x = 3z

Multiplying equation 1) by -1 and adding it to 2), we get

-x = x-216 so, x = 216/2 = 108

x = 108

Replacing this value in 3) we get

z = 108/3 = 36

z = 36

Replacing now in 2)

y+36 = 108, y = 108-36 and

y = 72

1 3<br> -- _ = _ y<br> 2 8<br> Please help me

(If you are)- Solving The Equation

1. Multiply both sides by eight over three

8/3•1/2 = 8/3•3/8 which gives you 4/3.


2. Swap the sides of the equation

4/3=y turns into y= 4/3 and that’s your answer. (y=4/3).

(Or if you’re working on)- Rewrite In Standard Form

Swap 1/2 and 3/8y , so it should be 3/8y=1/2.

Then multiply both sides by 8/3, and that should give you y=4/3.

Then multiply both sides of the equation by 3, and that should give you 3y = 4. And 3y=4 would be your answer.


Hope these helped! :)

A ball is thrown in the air that is 48 feet above the ground with an initial vertical velocity of 32 feet per second. The height
anastassius [24]

Answer:

h(t) = -16(t - 1)² + 64

Step-by-step explanation:

The function that would best to use to identify the maximum height of the ball is the vertex form of the parabola.

The standard form of a quadratic function is  

y = ax² + bx + c

The vertex form is

y = a(x - h)² + k

where (h, k) is the vertex of the parabola.

h = -b/(2a) and k = f(h)

In your equation, h(t) = -16t^2 + 32t + 48

a = -16; b = 32; c = 48

Calculate h

h = -32/[2(-16)]

h = (-32)/(-32)

h = 1

Calculate k

k = -16(1)² + 32×1 + 48

k = -16      + 32    + 48

k =  64

So, h = 1, k = 64, a = -16

The vertex form of the equation is  h(t) = -16(t - 1)² + 64.

The graph below shows h(t) with the ball at its maximum height of 64 ft one second after being thrown.
