Alright my friend so basically if we subtract 5 from 71 we get 66 plus 8 would be 74 so we would have to drop the temp 3 degrees to get back to 71 so the answer will be option B. fall 3 degrees

The length of a rectangular boat storage shed must be 4 meters more than the width, and the perimeter must be at least 112 meter
ludmilkaskok [199]

Answer:

The width of the rectangular shed can be 26, 27, 28, ........

Step-by-step explanation:

Let the width of the rectangular shed be, W = x

Then the length of the rectangular shed will be  

L = 4 + width

L = 4+x

We know that the perimeter of the rectangle is 2W+2L

Also it is given that the perimeter of the rectangular must be at least 112 meters

2W+2L >= 112

Substituting the values

2x+4x+8 \geq 112

2x+8+2x \geq 112

4x+8 \geq 112

4x \geq 112-8

4x>104

x \geq \frac{104}{4}

x \geq 26

Need help with problem #53! Arithmetic sequences!
ankoles [38]

When counting any sequence, it helps to have a simpler sequence to compare it to. The simplest one that I can think of is

1,2,3,4,5,\dots

because you instantly can tell the number of terms in the sequence by looking at the last number. We can see from the graph that the first few terms of the sequence a are 1, -3, -7, and we're told that its last term is -83. Our goal then is to turn this sequence:

1,-3,-7,\dots,-83

into this one:

1,2,3,\dots

The first thing which stands out in this sequence is the number of negative terms, so let's fix that by multiplying every term by -1:

1,-3,-7,\dots,-83\xrightarrow{\times{-1}}-1,3,7,\dots,83

Now, the main property of any arithmetic sequence is that they <em>increase or decrease by some constant amount</em>. Here, that number is 4, since -3 = 1 - 4 and -7 = -3 - 4. Knowing the importance of 4 in this sequence, our next step might be to turn every term into a multiple of 4 by adding 1:

-1,3,7,\dots,83\xrightarrow{+1}0,4,8,\dots,84

and since we're dealing with multiples of 4, a natural next step might be to divide every term by 4:

0,4,8,\dots,84\xrightarrow{\div4}0,1,2,\dots,21

And lastly, we can add 1 to every term to get our sequence into easily-countable form:

0,1,2,\dots,21\xrightarrow{+1}1,2,3,\dots,22

So, the sequence a has 22 terms.
