Answer:

Step-by-step explanation:

5) D

180- 65-70 = 45

3x+9=45

3x= 45-9

x=36/3=12

6)D

180-69-73=38

x+46 = 38

x= 38-46 = -8

7) A

180-24-132=24 (becasuse vertical angles are congruent)

3x=24

x=24/3=8

Find the minimum cost of producing 60000 units of a product, where x is the number of units of labor, at $99 per unit, and y is

Y_Kistochka [10]

Answer:

The minimum cost of producing 60000 units of a product is $105867

Step-by-step explanation:

Since x is the number of units of labor, at $99 per unit, and y is the number of units of capital expended, at $84 per unit, The cost C(x,y) is given by:

$C(x, y) = 99x + 84y$

$P(x, y) = 100x^{0.25}y^{0.75}$

For the minimum cost:

$100x^{0.25}y^{0.75}=60000\\x^{0.25}(\frac{33x}{28} )^{0.75}=600\\x^{0.25}(\frac{33}{28} )^{0.75}x^{0.75}=600\\x^{0.25+0.75}*1.131=600$

Using the langrage multiplier,

$99=0.25(100)x^{-0.75}y^{0.75}\lambda...(1\\84=0.25(100)x^{0.25}y^{-0.25}\lambda...(2$

Dividing both equation 1 and 2

$y=\frac{33}{28}x$

Substituting $y=\frac{33}{28}x$ in $100x^{0.25}y^{0.75}=60000$ , we get:

$x_{min}=530.44$ labor units

Substituting $x_{min}=530.44$ labor units in $y=\frac{33}{28}x$ , we get

$y_{min}=\frac{33}{28}*530.44=625.16$ labor unit

$C(x, y) = 99x + 84y=99(530.44)+84(635.16) = $105867\\$

The minimum cost of producing 60000 units of a product is $105867

The shape below is a composite figure made up of two rectangular prisms, what is the volume of the figure?

Shkiper50 [21]

Answer:

$11098{cm}^{3}$

Step-by-step explanation:

The formula to find the volume of a rectangular prism is

$v = length \times \: width \times height$

Since there are 2 shapes we are going to find the volume of each of them, then add them to find the volume of the entire shape.

The length of the rectangle that is standing is 62 cm, its width is 3 cm and its height is 13 cm. Therefore the volume is:

$v = l \times w \times h \\ v = 62 \times 3 \times 13 = 2418 {cm}^{3}$

On the other hand, the length of the rectangle that is lying down is 62 cm, its width is 20 cm (23-3=20), and the height is 7 cm. Therefore the volume is:

$v = l \times w \times h \\ v = 62 \times 20 \times 7 = 8680 {cm}^{3}$

The volume of the entire shape would then be:

$2418 {cm}^{3} + 8680 {cm}^{3} = 11098 {cm}^{3}$

Since 1sand=3.5compost you can set up the ratio 1/3.5 or 1 sand for every 3.5 compost. If you change the number of sand to three, then you multiply the top by three since 1*3=3. To keep the mixed number equal you would have to multiply the bottom number by three as well. This means that you can multiple all the sand by 3.5 to get how much compost is needed.

State whether the given measurements determine zero, one, or two triangles. C = 30°, a = 28, c = 14
