20% of a number is 1/5th of it so 50 × 5 is 250
Answer:
<em>The sales of ice lollies increased by 76 units between February and August</em>
Step-by-step explanation:
<u>Graph Reading</u>
Line graphs are visual ways of representing two or more data sets and their interrelation.
Graphs are pictures that show how one variable changes in relation to another.
Learning to properly read graphs is a matter of interpreting which pieces of information are useful.
The graph (in the red drawing) shows how sales of ice lollies changed in time. By February, the sales were about 4 units and by August sales were up to 80 units.
This means an increase of 80 - 4 = 76 units.
The sales of ice lollies increased by 76 units between February and August
We are tasked to solve for the smallest angle using the law of cosines given that the three sides of the triangle are 4,5 and 6.
a=4 , b=5, c=6
Angle 1:
cosA = 5² + 6² - 4² / 2*5*6
A=41.41°
Angle 2:
cos B = 4²+6² -5² /2*4*6
B= 55.77°
Angle C:
C = 180° - 41.41° - 55.77°
C = 82.82°
The smallest angle is A which is equal to 41.41°.
The correct answer is 6 because if u do 6 x 4(24) then to check your answer do 24 divided by 4 it will be 6
4/20 simplified would be 1/5. You must know what simplify means first. It means to break down a fraction to its simplest form. So, to simplify 4/20, you must divide 4 from the denominator and numerator. A numerator is a number that is the number above the line. A denominator is the number on the bottom of the line.
Dividing 4 from the denominator and numerator would make it 1/5. Therefore, the answer in simplest form is 1/5. Good luck!
