Describe a situation in the real world, where at least three types of science would be used to solve a problem. Use details to support your answer.

Answers

Answer:

Running

There are many different types of science that go into running, including the following:

Psychology (think you can/can't do it, how tired you are, how much further you can go/how much further you think you can go, dissociating and distracting,  associating and motivating, etc.)

Physiology (how fit one is, training, etc.)

Nutrition (food/drinks that are put into one's body, vitamins, etc.)

Physics ("The greater the force Fx, the greater the horizontal running velocity, and the longer the arc length, hence the faster the runner will run. Arm swinging is an important part of running. It serves to stabilize the body" - Real World Physics Problems (.com))

Newton's Three Laws (gravity, inertia, friction, net force exerted, equal and opposite reactions, etc.)

Biology (Chemical balance in your blood)

And more!

And remember: everything connects with something else, for example, nutrition can connect with all of the things on this list (yes, even phycology and physics). Hope this helps! :-)

Answers

Step-by-step explanation:

angle A = angle D

angle C common angle

angle E = 180 - 63 - 52

5x = 65

x = 13deg

Topic: congruence and similarity

If you like to venture further, do check out my insta (learntionary) where I regularly post useful math tips! Thank you!

Answer:

x = 13°

Step-by-step explanation:

Because of the given congruency,

Angle A = Angle D = 63°.

Angle C = 52°

Angle B = Angle E = 5x

Now, In Triangle ABC,

Angle A + Angle B + Angle C = 180°.

63° + 5x + 52° = 180°

115° + 5x = 180

5x = 65°

x = 13°

Pls i need help with this geometry problem. Its due today .

Answers

Answer:

63

Step-by-step explanation:

Set up the proportion

(6x+3)/17 = (8x - 1)/21                 Cross Multiply

21 * (6x + 3) = 17 (8x - 1)             Remove the brackets

126x + 63 = 136x - 17                 Subtract 126x from both sides

63 = 136x - 126x - 17                 Combine

63 = 10x - 17                              Add 17 to both sides

63 + 17 = 10x                             Combine the left

80        = 10 x                             Divide by 10

80/10 = x

x = 8

Now you want 8x - 1

8*8 - 1 = 63

Eric wants to send a package to his mother. If he chooses UPS, the fixed express fee is 10 dollars and each kilogram costs 2 dollars. For Fedex, the fixed fee is 20 dollars and each kilogram costs only 1 dollar. If the total costs of the two options are the same, how many kilogram of package does Ericsend? Write a system of equations in order to solve this problem.

Answers

Answer:

10kg

Step-by-step explanation:

For UPS;

express fee = $10

If one kg costs $2, then x kg of package will coat $2x

Total cost of shipping xkg of package will be 10+2x

For FedEx;

Fixed express fee = $20

If one kg costs $1, then x kg of package will coat $1x

Total cost of shipping x kg of package is 20+x

If the total costs of the two options are the same, then;

10+2x = 20+x

2x-x = 20-10

x = 10.

Hence Eric sent 10kg of package

we are asked to increase this amount by 77%

let us first find 77% of the amount £761

=77/100*761

=0.77*761

= £585.97

Step two:

Hence 77% of  £761 is £585.97

therefore the increase will be to add the two amounts together
