multiply the price by the discount then subtract the answer from the price
4 * 0.20 = 0.80
4-0.80 = 3.20
sale price is $3.20
Answer:
Lets take all factors into consideration first
The door is a rectangle and the area of a rectangle is length times width
Let the width be w
Let the length be l
Equation length × breadth = area
(w+48)w = 3024
w^2 + 48w = 3024
w^2 + 48w - 3024 = 0
w^2 + 84w - 36w - 3024 = 0
w(w + 84) -36 ( w + 84) = 0
(w + 84) (w - 36) = 0
w + 84 = 0 AND w - 36 =0
w = -84 and w = 36
Since width cannot be negative, the right answer is 36
How did I get 84 and 36? Well, I had to factorize 3024 and since 84 times 36 is 3024 and 84 minus 36 is 48, I chose them.
Answer:
Team 3 Turtle, by 4 minutes
Step-by-step explanation:
The speeds of each of the turtles can be computed from ...
speed = distance/time
Then for each of the turtles, the training pace is ...
Team 1 Turtle: (18 ft)/(6 min) = 3 ft/min
Team 2 Turtle: (12 ft)/(4 min) = 3 ft/min
Team 3 Turtle: (10 ft)/(2 min) = 5 ft/min
The times required to cover the 30 ft distance at these paces are ...
time = distance/speed
3 ft/min ⇒ (30 ft)/(3 ft/min) = 10 min
5 ft/min ⇒ (30 ft)/(5 ft/min) = 6 min
The 2nd-place finishers will take 10-6=4 minutes longer.
The expected winner is Team 3 Turtle by 4 minutes.
Answer:
43.96 ft, or about 44 ft
Step-by-step explanation:
C = 2πr. Here, π is approx. 3.14 and r is 7 ft. Thus, the circumference of the yard is
C = 2(3.14)(7 ft) = 43.96 ft
