Forces affect motions in living and nonliving things. In a human, swallowed food moves down the esophagus into the stomach, even if the human is upside down doing a handstand. Which force moves food through the esophagus into the stomach?
a:Frictional force in the esophagus moves food through the esophagus.

b:Gravitational force pulls food through the esophagus.

c:Magnetic force in the stomach pulls food through the esophagus into the stomach.

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

Answers

Answer:

a

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:

Fourth choice, 16

Step-by-step explanation:

The 2 angles are both 74 degrees, so the side that is facing each angle will be the same length, so:

9x - 73 = 3x + 23

add 73 to both sides

9x = 3x + 96

subtract 3x from both sides

6x = 96

divide by 6

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°

[50 pts] An even number, n, times the next consecutive number, n + 2, is equal to 168. Find the original number.

Answers

We are given:

An even number 'n', multiplied by the next consecutive even number is 168

Solving for n:

From the given statement, we can say that:

n(n+2) = 168                      [n multiplied by the next even number 'n+2']

n² + 2n = 168

n² + 2n - 168 = 0               [subtracting 168 from both sides]

We can see that we now have a quadratic equation, solving using splitting the middle term

n² + 14n - 12n - 168 = 0

n(n + 14) -12(n + 14) = 0      [factoring out common terms]

(n-12)(n+14) = 0

Here, we can divide both sides by either (n-12) OR (n+14)

Checking the result in both the cases:

(n + 14) = 0/(n-12)                     (n-12) = 0/(n+14)

n + 14 = 0                                 n - 12 = 0

n = -14                                      n = 12

Both these values are even and since we are not told if the number 'n' is positive or negative, both 12 and -14 are the possible values of n

Look at the arithmetic sequence below. Use the boxes to create a recursive formula for the sequence. 18, 21, 24, 27, 30, 33... Response area =

Answers

Answer:

we have:

u(1) = 18

u(2) = 21 = 18 + 3

u(3) = 24 = 18 + 3.2

u(4) = 27 = 18 + 3.3

.......

=> the sequence has: u(1) = 18

                                    d = 3

=> u(n) = 18 + 3(n - 1) = 3n + 15

so the recursive formula for the sequence is u(n) = 3n + 15

Answer:

Step-by-step explanation:

the shaded area would be

200*75=15,000 ft^2

from this are we have to subtract the are of the house and of the  garage

house= 40*40=1600

garage=24*30=720

house and garage= 1600+720=2320

15,000-2320=12,680

Answer:

12680 ft²

Step-by-step explanation:

First we will find the area of the house and then the garage.

They're both rectangles so we should use this formula [tex]A=l*w[/tex].

Area Of The House:

[tex]A=l*w\\A=40*40\\A=1600ft^2[/tex]

Area Of The Garage:

[tex]A=l*w\\A=24*30\\A=720ft^2[/tex]

Adding the two areas:

Now we have to add the two together to find how much of the space they take up in the yard.

[tex]1600+720=2320[/tex]

Area Of The Yard:

[tex]A=l*w\\A= 200*75\\A=15000ft^2[/tex]

Subtracting The Two Areas To The Yard's Area:

[tex]15000-2320=12680ft^2[/tex] and that is it!

You are an office manager. You have been asked to research the cost of an online messaging service. The service charges $3.25 per employee each month. However, if you sign up for a full one-year subscription, the charge drops to $2.80 per employee per month. Your office has 20 employees.

Answers

Answer:

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.

A pet store donated 50 pounds of food for adult dogs, puppies, and cats to an animal shelter. 17 3 4 pounds was adult dog food and 17 7 8 pounds was puppy food. How many pounds of cat food did the pet store donate?

Answers

Answer:

14 3/8 pounds

Step-by-step explanation:

Given

Total pounds donated = 50 pounds

Amount for dogs D = 17 3/4 pounds

Amount for puppy P = 17  7/8 pounds

Required

Amount of cat food C

Total = D + P + C

50 = 17 3/4 + 17 7/8 + C

50 = 71/4 + 143/8 + C

50 = (142+143)/8 + C

50 = 285/8 + C

C = 50 - 285/8

C = 400-285/8

C = 115/8

C = 14 3/8

Hence the pounds of cat food donated was 14 3/8 pounds
