.82
When changing a percentage to a decimal you will divide the number by 100. 82/100= .82
To change it back to percentage you will take .82 and multiply by 100 or simply move the decimal two stops to the right, making 82. or 82%
Divide 37 by 6.
6 x 6 = 36
So, 1 is left.
The answer: 6 1/6
1) A
2) False
3) C
Hope this helped :)
The correct answer: total interest = $1,784.56 and she would have $4,284.56 after 7 years
Solution:
1)
Statement Reason
x ║t Given
m∠16=m∠7 Given
m∠16=m∠1 Corresponding angles
m∠7=m∠1 Substitution
k║w Alternate exterior angles equal
(Property of parallel lines)
2)Part A:
Sum of angles in any triangle is 180 degrees.
m∠BAC+m∠ABC+m∠BCA= 180
Substituting the values :
4x+10+12x-6+3x+5=180
Adding like terms :
19x+9=180
19x=171
x=9.
Part B:
Substituting x value :
m∠BAC=4x+10=4(9)+10=46
m∠ABC=12x-6=12(9)-6=102
m∠BCA=3x+5=3(9)+5=32.
Part C:
m∠1=180-46=134
m∠2=180-102=78.
m∠3=180-32=148.
Part D:
Angle BAC and angle FAC are angle made on straight line and are linear .Such angles are called linear pairs.
Part E:
Angle BCE and Angle DCA are vertically opposite angles.
