Mathematics
1 answer:
Gemiola [76]3 years ago
6 0

Answer:

15% of 20 is 3

Step-by-step explanation:

because 15/100 can be reduced if you divide by 5 which will be 3/20. After you multiply 3/20 by 20/1. So 20*3 is 60 divided by 20 because 20*1 equals 20 you get 3.

PWEASE HELP ASAP my friends and I cant figure this out I'm hoping one of u guys can

The number of viruses was 4000 times greater than number of protozoa.

Step-by-step explanation:

Given,

Number of protozoa = 5*10^5

Number of viruses = 2*10^9

Let,

x be the number of times number of viruses is greater than number of protozoa.

Number of viruses = Number of time * Number of protozoa

2*10^9=(5*10^5)x

Dividing both sides by 5*10^5

\frac{2*10^9}{5*10^5}=\frac{(5*10^5)x}{5*10^5}\\\\4*10^3= x\\x=4*10^3 \\x=4000

The number of viruses was 4000 times greater than number of protozoa.

Heba ate \dfrac{1}{12} 12 1 ​ start fraction, 1, divided by, 12, end fraction of a box of cereal. Now the box is \dfrac{3}{4} 4
GrogVix [38]

9514 1404 393

Answer:

  5/6

Step-by-step explanation:

If q is the quantity of cereal in the box before Heba ate some, the problem tells us ...

  q - 1/12 = 3/4

  q = 3/4 + 1/12 = 9/12 + 1/12 = 10/12

  q = 5/6

There was 5/6 of a box before Heba ate.

We have the <span> Trigonometric Identities : </span>secx = 1/cosx; (sinx)^2 + (cosx)^2 = 1;
Then, 1 / (1-secx) = 1 / ( 1 - 1/cosx) = 1 / [(cosx - 1)/cosx] = cosx /
(cosx - 1 ) ;
Similar, 1 / (1+secx) = cosx / (1 + cosx) ;
 cosx / (cosx - 1)  +  cosx / (1 + cosx) = [cosx(1 + cosx) + cosx (cosx - 1)] / [ (cosx - 1)(cox + 1)] =[cosx( 1 + cosx + cosx - 1 )] / [ (cosx - 1)(cox + 1)] =  2(cosx)^2 / [(cosx)^2 - (sinx)^2] = <span> 2(cosx)^2 / (-1) = - 2(cosx)^2;
