She used 180 beads because 45x4 =180
Answer: A, 102
Step-by-step explanation:
Okay so just find the big square and subtract the holes
big square is 30x20 which is 600
hole #1 is 20x5 = 100
hole #2 is a triangle so you first find the base and height which are 10 and 5 respectively. Then use the triangle area formula a = 1/2bh to find that the triangle's area is 25.
Subtract the holes now
600-100-25 = 475
1 Gallon = 200 square feet covered so divide 475 by 200 to find how many gallons should be used. It's 3 gallons since you can't just buy a fraction of a gallon (Unless your being weird).
One gallon is 34, so 3 gallons is 3*34 = 102
Or in other words... A
hope you learned and can incorporate these methods for future problems :D!
Answer:
<h2><u><em>
n = 1/5m + (-2)/5</em></u></h2>
Step-by-step explanation:
-m + 5n = -2, for n
-m + 5n = -2
-m +5n + m = -2 + m
5n = m - 2
5n/5 = (m-2)/5
n = 1/5m + (-2)/5
Under C, I believe. When we have the same base (2 in this case), 2^1/4*2^1/4 can be written as 1/4+1/4 since it’s the same base. And 1/4+1/4+1/4+1/4 is 4/4 and that is 1 so 2^1 is 2.
Your answer is 22 x 18 x 9 = 3,564
