Answer:

46 orders.

Step-by-step explanation:

(10*12) - 2x = 28

120 - 2x = 28

-2x = 28 - 120

-2x = -92

x = -92/2

x = 46

The volume of the right circular cylinder is changing at a rate of approximately 50.265 cubic inches per second.

Given that a right circular cylinder is changing shape.

The radius is decreasing at the rate of 2 inches/sec

dr/dt = -2 inches

The radius is increasing at the rate of 2 inches/sec

dh/dt=5 inches

We have to find dv/dt when r is 4 inches and h is 6 inches.

Volume=πr²h

Differentiate with respect to 't' to find the change of volume:

[tex]\frac{dV}{dt}=\pi(2rh\frac{dr}{dt}+r^2\frac{dh}{dt})[/tex]

Plug in the values:

[tex]\frac{dV}{dt}=3.14(2(4)(-2)(6) + 16(5))[/tex]

[tex]=3.14(-96+80)[/tex]

[tex]=3.14(-16)[/tex]

[tex]=-50.265[/tex] inch³/sec.

Hence, the volume change is -50.265 inch³/sec.

Step-by-step explanation:

The force that moves food through the esophagus into the stomach is;

d:Push force from contractions of the esophagus moves food through the esophagus.

When we are sitting upright and eat food, the food moves down the esophagus and into the stomach.

Now, that will be a logical explanation because just like a flow, it goes with gravity position and would go from up down like a free fall.

However, when we are not sitting upright but upside down with our head on the ground and legs up, what happens is that the food still goes to the stomach via the oesophagus but this time because of the position of the body, the oesophagus will contract i.e. contraction in the walls of the food pipe which will lead to a push force that takes the food into the stomach.

Answer:

1,760 actual miles separate Springfield from Glenview.

Step-by-step explanation:

Scaling

Objects can be represented in a reduced or augmented size by using scaling which is basically multiplying or dividing real dimensions by a constant factor. We use scaling when representing geographic locations on a map.

The map has the scale:

0.75 inch => 220 miles

This gives us the scaling factor as 220/0.75. There is no need to divide.

We are given the distance from Springfield to Glenview is 6 inches on the map. The actual distance is

6*220/0.75 = 1,760

1,760 actual miles separate Springfield from Glenview.

Answer:

12 scoops of dog food are needed for 6 dogs,

Step-by-step explanation:

Proportions

The number of scoops of dog foods and the number of dogs are proportional variables.

We are given that 10 scoops of dog foods are used for 5 dogs. This gives a proportion of 10/5=2 scoops per dog.

We also know that 16 scoops are used for 8 dogs. The proportion is also 16/8=2 scoops per dog.

Thus, the constant of proportionality is 2.

For 6 dogs, you need to prepare 2*6 = 12 scoops of dog food.

12 scoops of dog food are needed for 6 dogs,

Answer:

  ? = 95°

Step-by-step explanation:

Long arc QR is twice the measure of inscribed angle QSR, so is 2×95° = 190°. That, together with the remaining short arcs ? and RS will make up the total circle of 360°.

  arc QR + arc RS + ? = 360°

  190° +75° +? = 360°

  ? = 360° -265° . . . . . . subtract 265° from both sides

  ? = 95°

The final cost for the service that offers the better deal is $56 per month, in total for the whole year it's $672.

The cost for the one that offers the worse deal is $65 per month.

Step-by-step explanation:

All we need to do is multiply the amount of money by the number of employees.

So:

20 × $2.80 = $56

(Calculations for worse deal)

20 × $3.25 = $65

Answer: $108.00

Step-by-step explanation:

$3.25 per employee, per month (3.25 x 20 x 12) = $780/ mo

$2.80 per employee, per month (2.80 x 20 x 12) = $672/mo

subtract the two, which equals $108.00 will be saved each year with the one-year subscription.
