The answer would be 3x+2=10x-5
Here first we have to understand which place is 10 thousand.
6- hundred thousand
2- ten thousand
0- thousand
0- hundred
0- ten
0- one
so as we can see 2 is in ten thousands place.
Now rounding ten thousands place is done by looking up to thousands place.
If the digit at thousands place is 5 or greater than 5 then we change our ten thousands value to one digit higher else it remains same.
Here we have 0 at thousands place , which is less than 5 , so we keep the number as it is.
Answer: 620, 000
Tan x = 8749/675
x= arctan (8749/675) arctan = tan^-1
x=85.59 degrees
The area of a kite:
A = d1 * d2 / 2
d1 = BD = 8 units
48 = 8 * AC / 2
48 * 2 = 8 AC
96 = 8 AC
AC = 96 : 8 = 12
Answer: D ) 12 units
Easiest way to work it out is to divide by ten, that gives 10% of your original number. Multiply that by two to get 20% and minus that from the original number to get the discount.
450/10 = 45 which is 10% of 450.
20% of 450= 10% x 2 or 45 x 2
therefor 20% of 450 is 90.
450-90 = the discount the shoppers recieve.
