First eliminate the opposites, which is 4 and -4.
(9x2) ÷ (4-2)
18 ÷ (4-2)
18 ÷ 2
= 9
You need to calculate the measure of each section in degrees considering the sum of all your data (56+40+24=120) and the total measure of the pie chart (360 degrees). after that just draw the angles using a protractor and it should come something like this.
hope this helps :)
Answer:
Yes
Step-by-step explanation:
Yes; points X and Y are fixed under the reflection, so they must lie on the line of reflection. Since two points determine a line, the line of reflection is XY.

Given:
lemon juice = 60% in the bottle
water = 1 liter.
Since lemon juice is 60% and the rest is water. Water is 40% of the bottle.
1 liter of water is equivalent to 40% of the bottle.
1/40% = 2.50 liters amount of total liquid in the water.
2.50 x 60% = 1.5 liters of lemon juice.
0.6x + 0.4x = 2.5
Step-by-step explanation:
change the angle to radian
then use formula 1/2 × π × radius square
