Answer:
it's -4 i don't know what you mean by regrouping, sorry
Step-by-step explanation:
When dealing with little odds you must know one part and the whole part. For number 1 a fraction , 7 is a part of a 11 which is the whole. For 2 a percent, 6% part and 100% whole, here you had to know that for 6% to exist there had to be a 100% . For 3 a ratio, the first number is part (2) and the second is whole (7). Look at pic for all work.
Each month the new total you be
initial amount * 1.024
Repeating the process for a year (=12 months) you get
initial amount * 1.024^12
Being initial amount = $100
100*1.024^12 = $132.92
After 1 year you will have $132.92
Just look at the top triangles
Angles in a triangle add up to 180°
To find the angle next to 36°:
It shows that all together its a 90° angle so you do 90-36= 54°
To find the angle next to 88°:
Angles on a straight line add up to 180° so you do 180-88= 92°
You now have the 2 of the angles in the triangle with angle 1
You now add these 2 angles so 54+92= 146°
and as angles in a triangle add up to 180° you do 180-146= 34°
So angle 1 is 34°
The 2 different fraction equations that both equal 6 are 12/2 and 36/6
