Answer: 75%
Step-by-step explanation:
Height given :
69, 62, 73, 67, 63, 65, 73, 71, 70, 66, 59, 75
The total number of height given = 12
The height less than 73 are 69 , 62, 67 ,63 , 65 , 71 , 70 , 66 , 59
The total number of heights less than 73 = 9
Therefore : the percentage of these students who are shorter than 73 inches = total number of students shorter than 73/ total number of height x 100
= 9/12 x 100
= 75%
Answer:
21
Step-by-step explanation:
We need to follow PEMDAS
15+3*2
We need to multiply first
3*2 = 6
Then we add
15+6

Make a systems of equations:
11x+13y=209
x+y=19
His percentage of change in the amount of quarts is 82.22%.
Initial amount of lemonade = 45 quart
End amount of lemonade = 8 quart
Change in amount = 45 - 8
= 36
Percent = 
= 
= 0.8222 * 100
= 82.22%
Hence, his percentage of change is 82.22%.

To find the value of the angle we start with tan(theta)= o/a now fill in variables tan(theta)= 39.05/18 then we have to move tan to the other side so we get theta = tan^-1(39.05/18) this will give us theta = 65
