how would you prefer to see your quiz score,as a fraction or as a percent? Explain. (what would you choose and why?)​

Answers

For me, a percent is easier to think about.  Knowing I scored 80% make sense.  80%, like 80¢ out of a dollar, makes sense and I can relate to it.

If you tell me I scored 52/65, I can't relate to that as easily, even though that's still 80%.

Shelby invests £14000 in a savings account. The account pays 2.5% compound interest per year.
Work out the value of her investment after 2 years.​

Answers

Answer:

70000

Step-by-step explanation:

Answer:

£14708.75

Step-by-step explanation:

Always start with the original amount, in this case 14000.

Then, because it's an increase, add 2.5 to 100. You could also think of it as adding 2.5% to 100%, which is 102.5%. We then divide that by 100.

So far our calculation is 14000 x 1.025.

We now need to do this for the two days on. We can do this in 2 ways.

1. 14000 x 1.025 x 1.025

or.

2. 14000 x 1.025^2

They're both the same thing.

We then type that calculation into your calculator and you should get £14708.75

Hope that helped :)

How might the crisis in biodiversity lead to a food crisis for humans?

Answers

Answer:

Hi and heres your answer!

Step-by-step explanation:

The crisis of biodiversity will lead to a food crisis for humans because:

1.No varieties in certain foods like plants and animals that are healthy

2.The Less food there is,more animals go extinct which means humans will go extinct too.

and finally 3: Without certain types of species like the bee, humans have no chance of survival (since bees pollinate flowers,fruits,and plants which could be used for human consumption and medicine)

Answer:

52% and 7

Step-by-step explanation:

There are 25 squares of which 13 are shaded , then

[tex]\frac{13}{25}[/tex] × 100% = 13 × 4% = 52°

(b)

1 square represents [tex]\frac{1}{25}[/tex] × 100% = 1 × 4% = 4%

Then 80% = 80% ÷ 4% = 20

That is for 80% , 20 squares require to be shaded

That is 7 more than the 13 already shaded
