Answer:
(-19,-3) or (5, -3)
Step-by-step explanation:
If b is located to the left side of a, then we need to add (-12) to the x-coordinate of a
b(-7+ [-12],-3) = b(-19,-3)
If b is located to the right side of a , then we need to add 12 to the x-coordinate of a.
b( -7+ 12, -3)= b(5 , -3)
Answer:
a) He calculated the area, not the circumference. The equation for the area of a circle is πr², while the equation for the circumference is 2πr.
b) He would need at least 3 quarts of paint. 200.96/75≈2.68 He would need that approximately 2.68 quarts of paint, but I suppose the question is asking you the least amount of whole number quarts of paint. The answer for that would then be 3.

Answer:
$60
Step-by-step explanation:
Find out how much is 1% of the price.
100% = 600
1% = 600 ÷ 100 = 6
Find out 10% and 20%
10% = 6 x 10 = 60
20% = 6 x 20 = 120
Find the difference.
120 - 60 = 60
Answer:
1680 ways
Step-by-step explanation:
Permutation has to do with arrangement
If a contractor builds homes of 8 different models and presently has 4 lots to build on, the number of ways he can arrange his homes is expressed as;
8P4 = 8!/(8-4)!
8P4 = 8!/4!
8P4 = 8*7*6*5*4!/4!
8P4 = 8*7*6*5
8P4 = 1680
Hence the can arrange his homes 1680 ways
