Answer:
None of the above
Step-by-step explanation:
=4+2y+7
x+8=(7x)+
(2y)+(4+8)=7x+2y+12
Show that if p(a) ⊂ p(b) then a ⊂ b.
<span>I will assume p() means power set. </span>
<span>proof: let x∈a, then {x} ∈ p(a) and so by hypothesis {x} ∈ p(b). However {x} could not be in p(b) unless x∈b. This shows that each element of a is an element of b and hence a ⊂ b.

Answer:
7 feet long
Step-by-step explanation:
This set up will give a right angle triangle where;
Length of the ladder is the hypotenuse = x
The distance of the ladder to the house is the adjacent = 3 feet
Angle of elevation theta = 72 degrees
Using the CAH in trigonometry identity;
cos theta = adjacent/hypotenuse
cos 72 = 3/hyp
hyp = 3/cos72
hyp = 3/0.4258
hyp = 7.05 feet
Hence the ladder is approximately 7 feet long
Answer:
going horizontally, 15, 3, 9, then 1, 3, 6, then 20, then, 40, 60
Step-by-step explanation:
C: 60.9% is the right answer
Step-by-step explanation:
The markup is calculated by using the formula
Given
Make Price = $22.99
Selling Price = $36.99
So the mark up will be:
Percent mark up will be:
Rounding off to the nearest hundredth percent
60.9%
Hence,
C: 60.9% is the right answer
