Answer:

Check Explanation

Step-by-step explanation:

Both Patterns start at 0

Pattern 1 follows the rule, add 9.

Pattern 1 has terms, 0, 9, 18, 27, 36, 45, 54, 63, 72, 81....

Pattern 2 follows the rule, add 3.

Pattern 2 has terms, 0, 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, 51, 54...

It is evident that all of the terms of the first pattern will eventually occur in the second pattern at some regular points.

- They both have the same first terms.

- Both Patterns have terms that are all multiples of 3.

- Every 3rd term that occurs after the first term in the second pattern (that is, the 4th term, 7th term, 10th term, 13th term, 16th term etc.), all represent the terms of the first pattern.

Hope this Helps!!!

The area of a rectangular fountain is (x^2 + 12x +20) feet squared. The width is (x + 2) feet.
n200080 [17]
Part A:
The total area = x² + 12x + 20 = (x+2)(x+10)
<span>The width = x+2
∴ Length = area / width = </span>[ <span>(x+2)(x+10) ] / (x+2) = x+10

Part B: </span>
<span>A 2-foot walkway is built around the fountain
</span>
<span>∴ The width = (x+2) + 2 + 2 = x + 6
The length = (x+10) + 2 + 2 = x +14

Part C:
</span><span>the total area covered by the fountain and walkway. </span><span>
   = (x+6)(x+14)
   = x² + 20 x + 84

See the attache figure for more explanation

A standard deck of cards contains 52 cards. one card is selected from the deck. ?(a) compute the probability of randomly selecti
Rama09 [41]
Let
P(h)= probability of selecting heart = 13/52= 1/4
similarly
P(s)= probability of selecting spade =1/4
P(c)= probability of selecting club =1/4
P(d)= probability of selecting diamond =1/4

a)

P(h or s)= P(h)+P(s)= 1/4+1/4=2/4=1/2=0.5

b)

P(h or s or c)=P(h)+P(s)+P(c)=1/4+1/4+1/4=3/4=0.75

c) 

P(2 or a diamond)=n(2heart, 2spade,2club,13 diamonds)/total number of cards

=(1+1+1+13)/52=16/52=4/13=0.3

or we could solve it as follows:

P(2 or a diamond)=P(2)+P(diamond)-P(2diamond)=4/52  +  13/52  + 1/52  = (4+13-1)/52=16/52=0.3

If Stacy brought 150 apples and gave 6 to each of her 4 friends, how much will she have left?
o-na [289]
The answer is 126 because you multiply 6 times 4 which equals 24 and subtract that from 150 so 150-24 = 126

4. (Claim 1 Example)
Citrus2011 [14]

Answer:

D

Step-by-step explanation:

using Sohcahtoa we know that we can only use Soh (since we have the opposite,16 and the hypotenuse, 20)

D is the only one that uses the correct equation of S = o/h

(this explanation isn't the best so please search up Sohcahtoa if it doesn't make sense)
