A: the mean salary is $500.
400+500+600=1500/3=500
b: the median is $500 also.
Answer: 8 inches
Step-by-step explanation:
320π in³= π (r²) (5 in)
64 in² = r²
r = 8 in
122° and angle 1 are alternate interior angles and hence they are equal.
m1 = 122°
122° + angle 2 = 180° [sum of co interior angles is 180°]
angle 2 = 180° - 122°
m2 = 58°
Question 1: this is simple adding
do the fractions first 1/4 + 3/4 = 4/4 or 1
then the whole numbers 1+1+1=3 gallons
Question 2: do it the same as the first you can make 1 1/2 into a mixed number which is 3/2 and make 4 into 8/2 then subtract 8/2 - 5/2= 3/2 or 1 1/2
Question 3: make into mixed numbers 5/3+5/3= 10/3 or 3 1/3
