The following equation estimates the average calories burned for a person when exercising, which is based on a scientific journa

Misha Larkins [42]

The program is an illustration of a sequential structure

<h3>What are sequential control structures?</h3>

Sequential control structures are programs that do not require loops and conditional statements

<h3>The actual program</h3>

The program in Python where comments are used to explain each line, is as follows:

#This gets input for age

age = int(input("Age: "))

#This gets input for weight

weight = (input("Weight: "))

#This gets input for the heart rate

heartRate = float(input("Heart Rate: "))

#This gets input for the time

time = int(input("Time: "))

#This calculates the calories burnt

calories = ((age * 0.2757) + (weight * 0.03295) + (heartRate * 1.0781) - 75.4991 ) * time / 8.368

#This prints the calories burnt

print('calories: {:. 2f} calories'. Format(calories))

A grocery store has two recycling machines

Thepotemich [5.8K]

Answer is 112%

kinda skeptical about my answer but i am going to give it my best shot, sorry if i get it wrong.

In percent-type questions I always go by this formula:

not a % %

original number : 100%

new number : new %

original number × new % = new number × 100%

here, the original numbers are 240 and 180 and the new % is +30% and -10% now let plastic be P and metal be M and let's elaborate this a bit further

plastic:

the first recycling machine took in 240 plastic bottles while the second took in 30% <u>more</u> plastic bottles, what we have to do here is to find out how much bottles the second machine took in as a form of integer, which is the new number; let that new number be X, let's plug this in the formula

$240:100+30\\X:130 \\$

notice: 130 is the new %

$240*130 = 100X\\31200 = 100X\\312=X$

the second machine took in 312 plastic bottles, let's save this answer for later

metal:

the first recycling machine took in 180 metal cans while the second took in 10% <u>less</u> plastic bottles, we do the same thing and find the new number, this time let it be Y:

$180:100-10\\Y=90$

90 is the new % here; also, notice how sometimes you either add or subtract percents, depending on what the problem demands.

$180*90=100Y\\16200=100Y\\162=Y$

Now we can conclude that the first recycling machine took in 240 plastic bottles and 180 metal cans and the second took in 312 plastic bottles and 162 metal cans.

here comes the hardest bit to apprehend and the final part of this problem, "the second machine recycled what percent (%) more items than the first?"

in other words, how much percent did the second machine recycle more.

to find that percent, first we need to add the plastic and metal "items" of both machines individually and turn them into percents: let the first machine be A and second machine be B:

A: 240+180=420

B: 312+162=474

again, using the same formula to find the new percent, let that percent be Z; plugging both A and B respectively:

$420:100\\474:Z$

$420Z=474*100\\420Z=47400\\Z= 112.857$ ≈ 112% more items than the first

now if you check the rounded up 112 and plug it back in to make sure of your answer: $420Z=47400$ you end up getting 47040, since it's rounded up, but when you plug the full 112.857 you get 47399.94, closest to 47400. Tip: when you plug in any value for check up, don't use the rounded up one.

At last, those steps are actually fast, especially with that formula it's so important. the explanation seems intimidating so read it slowly and take your time. if you have any other questions, feel free to ask. also, let me know if you know a faster method to solve this question. <3

Why are generic pharmaceuticals significantly cheaper than name brand ones? <br><br> NEED HELP ASAP

RSB [31]

Answer:

Generic drugs tend to cost less than their brand-name counterparts because generic drug applicants do not have to repeat animal and clinical (human) studies that were required of the brand-name medicines to demonstrate safety and effectiveness.

Generic pharmaceuticals are significantly cheaper than name brand ones because generic pharmaceuticals are not protected by patent law, so the lack of barriers to entry and increased competition keep prices down.

Also, the makers of generic drugs do not have to cover the cost of developing and marketing a new product.

Which situation is the best example of opportunity cost? A country chooses to produce bananas instead of wheat. A country choose

Citrus2011 [14]

The correct answer is A. Country chooses to produce bananas instead of wheat.

Opportunity cost is termed as value of choice. It is the important concept in economics and also the relationship which is between choice and scarcity.

A good example of opportunity cost is you can spend money and time on other things but you can not spend time reading books or the money in doing something which can help.

Opportunity takes important part in economic theory.
