Answer:
D. 4
Step-by-step explanation:
First find the area of 1 tile
= length * breadth
= 8 * 5
= 40= 40/10000 = 0.004
no. of tiles= 1000
therefore, total area of 1000 tiles = area of room= 1000*0.004
=4
1. Remove the parenthesis using the next rules:
2. Start to remove the parentheses from the center to the edges:
<h2>Then, the solution is 8</h2>
30x + 30y = 450
20x + 25y = 345
answer: 3 square ft per minute
Answer:for the first one, you should probably do a table of values then answer the question, i usually find that helpful
Step-by-step explanation:
Entire distance = 1,320
Entire time = 5 hours
bus avg = 40 km/h
plane avg = 600 km/h
Working this by trial and error
1 hour bus 4 hour plane = 40 + 2,400 = 2,800 distance (too high)
2 hour bus 3 hour plane = 80 + 1,800 = 1,880 distance (too high)
3 hour bus 2 hour plane = 120 + 1,200 = 1,320 distance (Correct!!)
So, they traveled 3 hours by bus and 2 hours by plane
(yes, you had the right answer).
