A toy manufacturer uses 90 pints of plastic to make 600 action figures. If they use 810 pints of plastic in an 8 hour shift, how many action figures are made per hour?

A) 600 action figures per hour

B) 625 action figures per hour

C) 650 action figures per hour

D) 675 action figures per hour

Answers

Answer:675(d)

Step-by-step explanation:so you take ratio

90-600

810-x

x=5400

After you divide 5400 by 8 hours and you get 675- to get how much figures he get for one hour

Final answer:

To find out how many action figures are made per hour, divide the amount of plastic used per hour by the amount of plastic used to make one action figure. In this case, 113 action figures are made per hour.

Explanation:

To find out how many action figures are made per hour, we need to determine the amount of plastic used per hour and then divide it by the amount of plastic used to make one action figure.

First, we need to find the amount of plastic used per hour. Since 810 pints of plastic are used in an 8-hour shift, we divide 810 by 8, which gives us 101.25 pints of plastic per hour.

Next, we need to determine how many action figures can be made with 101.25 pints of plastic. We divide 101.25 by 90 (the amount of plastic used to make 600 action figures), which gives us 1.125 action figures per pint of plastic.

Finally, we multiply 1.125 by 101.25 to find the number of action figures made per hour. This gives us 113.4375 action figures per hour. Since we can't have a fraction of an action figure, we round this to the nearest whole number, which is 113 action figures per hour.

find the distance between the two points 5,6 and 0,-6. Show your work​

Answers

Answer:

The distance between two points is √169 or 13.

Step-by-step explanation:

In the question we need to find the distance between two points 5,6 and 0,-6 given.

Distance between two points can be found using the formula:

[tex]d(P1,P2) = \sqrt{(x_{2}-x_{1})^2 + (y_{2}-y_{1})^2}[/tex]

Putting the given points in the formula we get,

x₂ = 0, x₁ = 5, y₂= -6, y₁= 6

[tex]=\sqrt{(0-(5))^2 + (-6-(6))^2} \\=\sqrt{(0-5)^2 + (-6-6)^2}\\=\sqrt{(-5)^2 + (-12)^2}\\=\sqrt{25 + 144}\\=\sqrt{169}\\=13[/tex]

So, the distance between two points is √169 or 13.

What is the linear function equation represented by the graph?

Answers

Answer:

y = (3/5)x + 3

Step-by-step explanation:

You can see immediately that the y-intercept is (0, 3).

As we go right from the point (-5, 0) to the point (0, 3), x increases by 5 and y increases by 3.  Thus, the slope of this line is m = rise / run = 3/5.

Starting with the generic y = mx + b, we get y = (3/5)x + 3.

Answer:

Y=3/2x-3

Step-by-step explanation:

3/2 is the slope. Remember, rise/run. so the rise is 3 and the run is 2. so up three since its positive and right 2 cuz its positive. and the -3 is the y inercept. hope this helps love :)

The postal service offers flat-rate shipping for priority mail in special boxes. Today, Anna shipped 10 small boxes and 6 medium boxes, which cost her $126 to ship. Meanwhile, Jeffrey shipped 5 small boxes and 6 medium boxes, and paid $96. How much does it cost to ship these two sizes of box?

Shipping costs $___ for a small box and $___ for a medium box.

Answers

Answer:

shipping cost $6 for a small box and $11 for a medium box

Step-by-step explanation:

The question is on formation of simultaneous equations

Anna shipped 10sb + 6mb =$126

Jeffrey shipped 5sb + 6mb=$96

Let small boxes,sb, be represented by x

Let medium boxes, mb, be represented by y

Equations

10x+6y=126------------------------(a)

5x+6y=96.......................................eliminate y by subtraction

5x=30.................................................divide by 5 to remain with x

x=30/5= 6......................................substitute value of x in equation (a)

(10×6) + 6y =126

60+6y=126

6y=126-60

6y=66..............................................divide by 6 both sides to get y

y=66/6= 11

Solution

x=6 and y=11

shipping cost $6 for a small box and $11 for a medium box

Step-by-step explanation:

It is C.

Volume-πr^2h

r-11

h-15

11^2*15

=1815π

Answer:

The correct option is C.

Step-by-step explanation:

From the given figure it is clear that the radius of the cylinder is 11 units and the height of the cylinder is 5 units.

The volume of the cylinder is

[tex]V=\pi r^2h[/tex]

Where, r is radius and h is height.

Substitute x=11 and h=15 in the above formula.

[tex]V=\pi \times (11)^2\times (15)[/tex]

[tex]V=\pi \times 121\times (15)[/tex]

[tex]V=1815\pi[/tex]

The volume of the cylinder is 1815π unit³.

Therefore the correct option is C.

A rectangular prism has a height of 12 centimeters and a square base with sides measuring 5 centimeters. A pyramid with the same base and half the height of the prism is placed inside the prism, as shown in the figure.

The volume of the space outside the pyramid but inside the prism is
cubic centimeters.

Answers

Answer:

250 cubic cm

Step-by-step explanation:

First step is to measure the volume of the rectangular prism... which is easy... it's the width * length * height.  Since we have a square base, the width and length are the same: 5 cm.  The volume is then: 5 * 5* 12 = 300 cubic cm.

The volume of a pyramid is obtained by the following formula:

V = (1/3) * base_area * height

We have the base area (5 * 5 = 25) and we have the height: 6 cm (half of 12 cm).

So, the volume of the pyramid is:

V = (1/3) * 25 * 6 = (1/3) * 150 = 50 cubic cm

The volume inside the prism but OUTSIDE the pyramid is then the volume of the prism (300 cubic cm) - the volume of the pyramid (50 cubic cm), so 250 cubic cm.

17) A marble paperweight shaped like a pyramid weighs 0.15 lbs. How much does a similarly shaped
marble paperweight weigh if each dimension is three times as large?

Answers

Answer:

The weight of the larger marble paperweight is 4.05 lb

Step-by-step explanation:

we know that

If two solids are similar, then the ratio of its weights (or volumes) is equal to the scale factor elevated to the cube

Remember that the scale factor is the ratio between corresponding sides

Let

z ------> the scale factor

x -----> the weight of the larger marble paperweight

y -----> the weight of the original marble paperweight

[tex]z^{3} =\frac{x}{y}[/tex]

In this problem we have

[tex]z=3[/tex]

[tex]y=0.15\ lb[/tex]

substitute and solve for x

[tex]3^{3} =\frac{x}{0.15}[/tex]

[tex]x=(27)(0.15)=4.05\ lb[/tex]

therefore

The weight of the larger marble paperweight is 4.05 lb

identify the type of variation represented by y=3/x

Answers

Answer:

Inverse variation

Step-by-step explanation:

Given equation is [tex]y=\frac{3}{x}[/tex].

Now we need to identify the type of variation represented by  [tex]y=\frac{3}{x}[/tex].

We know that there are two type of variations direct and inverse.

If y and x are in direct variation then we write equation as  [tex]y=kx[/tex].

where k is the constant of variation.

If y and x are in inverse variation then we write equation as   [tex]y=\frac{k}{x}[/tex].

Given equation  [tex]y=\frac{3}{x}[/tex] looks similar to  [tex]y=\frac{k}{x}[/tex].

So that means finala answer is "Inverse variation".
