Answer:
$395.83
Step-by-step explanation:
to solve, we first need to subtract what we already have, first the scholarship, wich is a set amount being taken from the original amount
12'000 - 2'500 = 9'500
now we have the second subtracting factor, but this one isn't set in stone and defined, it is half of the amount his parents will pay, so what we can do is divide what we have by two, wich will give us 2 halves
9'500 / 2 = 4'750
now all we have to do is divide again but this time for each month that Daniel needs to save up in, in this case 12
4'750 / 12 = 395.83 (note1)
and there we have it, that is the minimum amount Daniel would save each month
note1: (3 goes on for infinity, usualy this is represented by a line above the repeating number, this is the case of a repeating decimal)
I think right is correct ( - 1, 5 )
Step-by-step explanation:
2 things to remember for problems like this :
the sum of all angles in a triangle is always 180 degrees.
the law of sines :
a/sin(A) = b/sin(B) = c/sin(C) or upside-down (whatever fuss the situation better), with the sides being always opposite of the angles.
so, now for the given problems :
4.
x/sin(90) = 12/sin(29)
x/1 = x = 12/sin(29) = 24.75198408...
rounded x = 24.8
5.
the opposite angle of x is
180 - 90 - 16 = 74 degrees.
x/sin(74) = 37/sin(90) = 37
x = 37×sin(74) = 35.56668275...
rounded x = 35.6
6.
the opposite angle of x is
180 - 90 - 58 = 32 degrees.
x/sin(32) = 22/sin(58)
x = 22×sin(32)/sin(58) = 13.74712574...
rounded x = 13.7
7.
the opposite angle of 15 is
180 - 90 - 51 = 39 degrees.
x/sin(51) = 15/sin(39)
x = 15×sin(51)/sin(39) = 18.52345735...
rounded x = 18.5
Answer:
141°
Step-by-step explanation:
It's an octagon so the Sum of interior angles is: (8-2)×180=1080
5x+133+16+126+162-12+30=5x+455=1080
5x=625
x=125
x+16=141
