Answer: 3x3=9, 4x5=20, 8x9=72, and 7x3=21!
Step-by-step explanation:
Step 1
<u>Find the value of x</u>
we know that
-------> by corresponding angles, because the given lines are parallel
Solve for x
Step 2
<u>Find the value of y</u>
we know that
substitute the value of x and solve for y
therefore
<u>the answer is the option B</u>
Let's give some distances
100 up 100 flat 100 down meters
then return 100 up 100 flat 100 down
time required (distance/rate = time ) 200/100 + 200/120 + 200 / 150 = 5 hr
distance 600
distance / time = average speed = 600/5 = 120 m/s
Answer:
cube root 64, 4.2, sqrt 19
Step-by-step explanation:
cube root of 64 = 4
sqrt 19 = 4.3
