3.consecutive even integers are two numbers apartx = 1st even integerx+2 = next consecutive even integerx+(x+2)=462x+2=462x=44x=22so the two consecutive even integers are 22 and 24

4.Let's say that one of the consecutive even integers is n. That means that the next two are (n + 2) and (n + 4), for simplicity's sake. You can also say that the other two are (n - 2) and (n - 4) or that they are (n - 2) and (n + 2), but they would all give you the same numbers in the end. So if three consecutive even integers add up to 198: n + (n + 2) + (n + 4) = 198 We can solve for n: 3n + 6 = 198 3n = 192 n = 64 The other two integers are then (n + 2) = 66 and (n + 4) = 68.

5.It would be the  3rd option n + n+1 + n+2 + n+3 = 866.The perimeter is length + width + opposite length + opposite width, or in other words: 150 = 2L + 2W 
<span>Also L = W + 15 </span>

<span>So, 150 = 2(W + 15) + 2W = 4W + 30 </span>

<span>This means, 4W = 120 or W = 30 </span>
<span>Therefore: L = 30 + 15 = 45 
7.</span>Let the price be p.  Then 1.10p = $8.25.  Solving for p, p = $750 (answer)

Please explain all three questions
taurus [48]

Answer:

1) Standardization

2). 1:1.25

3) 4cm

Step-by-step explanation:

The manipulation of scale variables to ensure comparability with other scales and enable comparisons to be made.

1:x = 9.6:12

x= 1: 1.25

9.6/12 = AC/5

AC= (5*9.6)/12

AC= 48/12

AC= 4cm

Alan has forgotten his 4-digit PIN code.
MA_775_DIABLO [31]
200

If the number is divisible by 5, then the last digit should be either 5 or 0.

First digit is fixed.

Second digit can be 10 ways.

Third digit can be 10 ways.

Fourth digit can be 2 ways.

So total number of digits 1 x 10 x 10 x 2 = 200

A boat is pulled toward a dock by means of a rope wound on a drum that is located 6 ft above the bow of the boat. If the rope is
Monica [59]

Answer:

Step-by-step explanation:

Given that:

The height of the dock (h) = 6

Let represent d to be the distance between the boat and the dock

Let the length of the rope between the boat and the drum be denoted by (l)

Then, the rate of change for the length of the rope be:

dl/dt = -5 ft/s

Using Pythagoras rule to determine the relationship between these values, we have:

l^2 = h^2 +d^2

l^2 = 6^2 + d^2

l^2 = 36 + d^2

We relate to:  2l * \dfrac{dl}{dt} = 2d* \dfrac{dd}{dt}

From the question;

l = 34,

So to find \dfrac{dd}{dt}, we get;

d = \sqrt{l^2 - 36}

d = \sqrt{34^2 - 36}

d = \sqrt{1156- 36}

d = \sqrt{1120}

d = 33.46

So, we have:

\dfrac{dd}{dt}= \dfrac{l}{d} \times \dfrac{dl}{dt}

\dfrac{dd}{dt}= \dfrac{34}{33.46} \times - 5

\dfrac{dd}{dt}= 1.016 \times - 5

\dfrac{dd}{dt}=-5.08 \ ft/sec

A sequence of patterns is made from circular tiles and square tiles. Here are the first three patterns in the sequence:
skad [1K]

Answer:

  a) 49

  b) 84

  c) (B) -- always odd

Step-by-step explanation:

We observe that the number of square tiles is the square of the pattern number. The number of circular tiles is 1 more than the pattern number on each side of the square.

  square tiles = n²

  circular tiles = 4(n +1)

__

<h3>a) </h3>

7² = 49 square tiles are needed for pattern number 7.

__

<h3>b)</h3>

4(20+1) = 84 circular tiles are needed for pattern number 20.

__

<h3>c) </h3>

The parity of the number of square tiles matches the parity of the pattern number. (The square of a number has the same parity as the number.) Since 4 is a factor in the number of circular tiles, its parity is always even. The parity of the total number of tiles will match the parity of the pattern number.

When the pattern number is odd, the total number of tiles will always be odd. (B)
