Quiz Answer Key and Fun Facts

Answer:
**190**

First you must multiply 2 by 90, and 3 by 20 , then divide 100 by 2, then add the result then subtract it.

Q: 2*90+3*20-100/2

= 180+60-50

= 240-50

= 190

Answer:
**-74**

Multiply 25 by itself 2 times. Then subtract.

Q: 25^2-199-500

= 625-699

= -74

Answer:
**2520**

Let's start with 1*2*3*4*5*6*7*8*9*10 which is certainly divisible by all of them, but it's not the lowest number.

If the answer is divisible by 10 then it is divisible by 2 and 5.

If the answer it's divisible by 9 then it is divisible by 3.

If it's divisible by 8 then it is divisible by 2 and 4.

If it's divisible by 8 & 9 then it is divisible by 6.

Remove all the duplicates and the lowest number is:

9 x 8 x 7 x 5

= 2520

Let's start with 1*2*3*4*5*6*7*8*9*10 which is certainly divisible by all of them, but it's not the lowest number.

If the answer is divisible by 10 then it is divisible by 2 and 5.

If the answer it's divisible by 9 then it is divisible by 3.

If it's divisible by 8 then it is divisible by 2 and 4.

If it's divisible by 8 & 9 then it is divisible by 6.

Remove all the duplicates and the lowest number is:

9 x 8 x 7 x 5

= 2520

Answer:
**1 000 000**

You must get the value of bigger 9 and the smaller 9. Then divide the value of the bigger 9 to the smaller 9.

You must get the value of bigger 9 and the smaller 9. Then divide the value of the bigger 9 to the smaller 9.

Answer:
**2**

Simplify the inside the parenthisis then reverse the equation.

Q:((2*14+25-10-1)/2)^x=441

= ((28+25-11)/2)^x=441

= ((42)/2)^x=441

= 21^x=441

x=2 (21 squared = 441)

Simplify the inside the parenthisis then reverse the equation.

Q:((2*14+25-10-1)/2)^x=441

= ((28+25-11)/2)^x=441

= ((42)/2)^x=441

= 21^x=441

x=2 (21 squared = 441)

Answer:
**25**

First get the median of numbers from 15520 to 15530 and then add 100 and then get the cube root.

median=15525

+100=15625

25^3=15625

median=15525

+100=15625

25^3=15625

Answer:
**x=20 and y=8**

Add the 2 equations then do the rules of algebra.

2x+5y=80

2x=80-5y

x=40-5/2y

7x-5y=100

7(40-5/2y)-5y=100

280-35/2y-5y=100

560-35y-10y=200

560-200=35y+10y

360=45y

8=y

x=40-5/2y

x=40-5/2*8

x=40-20

x=20

Add the 2 equations then do the rules of algebra.

2x+5y=80

2x=80-5y

x=40-5/2y

7x-5y=100

7(40-5/2y)-5y=100

280-35/2y-5y=100

560-35y-10y=200

560-200=35y+10y

360=45y

8=y

x=40-5/2y

x=40-5/2*8

x=40-20

x=20

Answer:
**26**

First you must multiply 3 by 5, then multiply the result by itself 2 times, then subtract it in 100 and 99.

Q:(3*5)^2-100-99

= 15^2 -199

= 225-199

= 26

First you must multiply 3 by 5, then multiply the result by itself 2 times, then subtract it in 100 and 99.

Q:(3*5)^2-100-99

= 15^2 -199

= 225-199

= 26

Answer:
**-36**

First you must do the inside of the parenthesis (aka inside the brackets) then subtract. Since the result is 64, change the equation into 64+(-100).

Q:((2*5+1-9)^6)-100

= ((10+1-9)^6)-100

= 2^6-100

= 64-100

= -36

First you must do the inside of the parenthesis (aka inside the brackets) then subtract. Since the result is 64, change the equation into 64+(-100).

Q:((2*5+1-9)^6)-100

= ((10+1-9)^6)-100

= 2^6-100

= 64-100

= -36

Answer:
**110**

First you must do the inside the parenthesis (inside the brackets) and then multiply then subtract.

Q:(5^2-6)*11-99

= (25-6)*11-99

= 19*11-99

= 209 -99

= 110

First you must do the inside the parenthesis (inside the brackets) and then multiply then subtract.

Q:(5^2-6)*11-99

= (25-6)*11-99

= 19*11-99

= 209 -99

= 110
