Answer:
10 its just 10 or smthing
46% is equal to 14/25
14/25 is equal to 46/100 (multiply 14/25 times 4/4) and that is 46%
Answer:
a(85) = -1033
Step-by-step explanation:
Explicit Arithmetic Sequence:
an = a1 + d(n-1)
d = -12 (by -37 + 25)
a(85) = -25 + -12(85-1)
a(85) = -1033
Answer: " y = 30° " .
_____________________________________
<u>Note</u>: The sum total of the measure of all angles lying on a straight
line is 180°.
So; x + y + z = 180 .
Given: x = 2y ;
z = 3y ;
__________________
Find the value of: " y " ;
_______________________
Since: x + y + z = 180 ;
Substitute: "2y" for "x" ;
and: "3y" for "z" ;
_______________________
2y + y + 3y = 180 ;
6y = 180 ;
______________________
Divide EACH SIDE of the equation by "6" ; to isolate "y" on one side of the equation; and to solve for "y" ;
___________________________
6y/ 6 = 180 / 6 ;
y = 30 ;
____________________________
Let us check our work;
____________________________
2y + y + 3y = 180 ;
Substitute our solved value: "30" ; for "y" ; in the equation; to see if the equation holds true:
____________________________
2(30) + 30 + 3(30) =? 180 ?
____________________________
60 + 30 + 90 = ? 180 ?
____________________________
90 + 90 = ? 180 ? Yes!
____________________________
A=1/2ab
Replace the variables with their value
15=1/2(3/2)b
Multiply 1/2 and 3/2

15=3/4b
Divide 3/4 on both sides
15/(3/4) is the same thing as

45/4=b
