Answer:

l = 40

Step-by-step explanation:

Since Perimeter comes from P = 2l + 2w so 180 = 2l + 2(50)

180 = 2l + 100

180-100 = 2l

80 = 2l

so l = 40

2 people have calculators, one person starts at 100 and subtracts 7 each time. Another starts at zero and adds 3 each time. If t
zaharov [31]

Answer:

  Yes, after 10 key presses, both will arrive at the number 30.

Step-by-step explanation:

The difference between the numbers on the calculators is reduced by 10 with each key press. After 10 key presses, the initial difference of 100 will be zero. After 10 key presses of (-7), the calculator starting at 100 will be ...

  100 +10(-7) = 30

After 10 key presses of (+3), the calculator starting at 0 will be ...

  0 +10(+3) = 30

Both calculators will show 30 after 10 key presses.

Prove that A is in the subset B if P(A) is in the subset P(B)
natima [27]
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.

I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!
