Answer:
60%
Step-by-step explanation:
40-16=24
24/40=0.6
0.6*100=60
First, work out the difference (decrease) between the two numbers you are comparing.
Decrease = Original Number - New Number
Next, divide the decrease by the original number and multiply the answer by 100.
% Decrease = Decrease ÷ Original Number × 100
Answer:
its A im pretty sure
Step-by-step explanation:
First you have to look to see if you can isolate h. to do this you need to divide 2g on both sidesmaking the equation into f/2g=h.
just an extra little fact, we divide the 2g because it was multiplied as 2gh, to move it to the other side you do the opposite to it, therefore it being division :)
The answer to this question would be: p+q+r = 2 + 17 + 39= 58
In this question, p q r is a prime number. Most of the prime number is an odd number. If p q r all odd number, it wouldn't be possible to get 73 since
odd x odd + odd= odd + odd = even
Since 73 is an odd number, it is clear that one of the p q r needs to be an even number.
There is only one odd prime number which is 2. If you put 2 in the r the result would be:
pq+2= 73
pq= 71
There will be no solution for pq since 71 is prime number. That mean 2 must be either p or q. Let say that 2 is p, then the equation would be: 2q + r= 73
The least possible value of p+q+r would be achieved by founding the highest q since its coefficient is 2 times r. Maximum q would be 73/2= 36.5 so you can try backward from that. Since q= 31, q=29, q=23 and q=19 wouldn't result in a prime number r, the least result would be q=17
r= 73-2q
r= 73- 2(17)
r= 73-34=39
p+q+r = 2 + 17 + 39= 58
1.2 e⁻¹¹
Because you need a number between 1 and 10 for scientific notation. So you move the decimal over 11 places. Since you move it to the right, it becomes a negative exponent.
