10 3/5 is the correct answer
Step-by-step explanation:
by basic proportionality therom
x/33=14/20
20×x=14×33
20x=462
x=462/20
x=23.1
The distance formula is sqrt((x1-x2)^2 + (y1-y2)^2), therefore (3-(-6))^2 = 9^2 and (5 -(-6))^2 = 11^2 so 121 + 81 = sqrt(202), this converted to decimal is ~14.21, so D.
<span>A.) 18 feet in 20 minutes
B.) 90 feet in 2.5 hours
C.) 20 yards in 1.5 hours
D.) 3.6 yards in 15 minutes
</span>
A) 18/20=0.9 ft per min
B) 2.5 hours equals 150 minutes . 90/150=0.6 ft per min
C) 20 yds = 60 ft 1.5 hours = 90 minutes 60/90≈0.67 ft per min
D) 3.6 yds = 10.8 ft 10.8/15=0.72
Therefore the fastest would be 0.6 ft per minute therefore, choice
B) 90 feet in 2.5 hours
Hello,
7) A∪C={1,2,3,4,5,7,9}
8) A∩B={2,4}
C'= complement of C ={2,4,6}
9) A∪B∩C'={1,2,3,4,6,8}∩{2,4,6}={2,4,6}
10) A∪(B∩C')={1,2,3,4}∩{2,4,6}={1,2,3,4,6}
