Answer:x=3
Step-by-step explanation:
the 3 angles of a triangle equal 180
you add 105 and 46, which equals 151
you subtract 151 from 180 to see what the missing angle is (29)
you would make 6x+11 equal to 29
-subtract 11 from 29= 18
6x/6, 18/6
the answer is 3
hope this helps! :)
im sorry but I don't understand what its asking
Answer:
257
Step-by-step explanation:
36% of 275 is 99. 100% of 275 is 275, therefore 36 percent of 275 equals 99
Answer:
she use 750 mL of 0.22% solution and 250 mL of 0.1%
Step-by-step explanation:
given data
salt water solution 1 = 0.1%
salt water solution 2 = 0.22%
1 liter of solution contains salt = 0.13%
solution
we will consider here quantity in liters of the 0.22% solution is = x
so that the quantity of 0.01% solution will be = 1 - x
so amount of salt in the mix will be as here
0.22 % (x) + 0.1 ( 1-x) = 0.13% (1)
solve it we get
x = 0.25
and
1-x will be = ( 1 - 0.25 ) = 0.75
so she use 750 mL of 0.22% solution and 250 mL of 0.1%
Average rate of change from x = 0 to x = 1 is
Average rate of change from x = 2 to x = 3 is
The average rate of change of both sections are equal.
