This is the last one but how do you find y ? what do I subtract 5 from ?

Mathematics

Answer:

y = 250

Step 1:

To solve, we plug in 50x for y.

50x=200+10x

Then, we subtract the 10x from the right side. Our goal is to get the x by itself first.

40x=200

Then, we divide both sides by 40, since we have to get the x by itself.

\frac{40x}{40}=x\\\\\frac{200}{40} =5

x = 5

Step 2:

Now that we found x, we plug in 5 to the original equation and solve from there.

y=200+10(5)\\y=200+50\\y=250

y = 250

Answer:

  A. 1 rectangle, 2 triangles

  B. AB = AE = 5

  C. 36.5 square units

Step-by-step explanation:

<h3>A.</h3>

The attached figure shows 1 rectangle (square) and two triangles.

__

<h3>B.</h3>

These sides are aligned with the grid, so their length is simply the difference in coordinates along the line:

  AB = 2 -(-3) = 5

  AE = 3 -(-2) = 5

__

<h3>C.</h3>

The area of the square is ...

  A = s^2 = 5^2 = 25

The area of triangle BCF is ...

  A = 1/2bh = 1/2(3)(5) = 15/2

The area of triangle CDE is ...

  A = 1/2bh = 1/2(8)(1) = 4

The total area is the sum of the areas of the square and two triangles:

  total area = 25 +7.5 +4 = 36.5 . . . square units

_____

<em>Additional comment</em>

We note that segment CE divides the figure into <em>trapezoid</em> ABCE and <em>triangle</em> CDE. The trapezoid has bases 5 and 8, and height 5, so its area is ...

  A = 1/2(b1 +b2)h = 1/2(5 +8)(5) = 32.5

Triangle CDE has the same area as computed above, 4 square units. So, the total area of the figure is ...

  32.5 +4 = 36. 5 . . . . square units

NO ONE EVER HELPS ME , PLEASE HELP ME I NEED HELP!
Makovka662 [10]

Answer:

A is the answer  

12 in

first substitute the variables

then 78=1/2h(5 + 8)

this makes it an equation

add similar terms which equals to

78=1/2xhx13

then divide both sides by 13

6=1/2xh

lastly divide both sides by 1/2

12=h

Step-by-step explanation:

proof

A=1/2x12(5 + 8) then

A=1/2x12x13  then

   A=6x13  then

       A= 78in^2

suppose the depth of the tide in a certain harbor can be modeled by y = 20 + 5 cos (pi/6 t), where y is the water depth in feet
Rom4ik [11]

Answer:

- high tide occurs at 12 noon and 12 midnight

- Low tide occurs at 6 a.m and 6 p.m

- maximum depth value = 20 ft

- Minimum depth value = 15 ft

Step-by-step explanation:

The depth is modelled as;

y = 20 + 5 cos (πt/6)

We are told that t = 0 represents 12:00 midnight.

This is high tide because at t = 0, the cos function will be at it's maximum value of 1 since cos 0 = 1.

Max depth value is;

y = 20 + 5(0)

y = 20 ft

Minimum depth value will be the low tide and it will be when the cos function is equal to -1.

Thus;

y = 20 + 5(-1)

y = 15 ft

Since t represents number of hours and since at 12 midnight, t = 0, thus; high tide will occur again at;

12 noon

Also, let's check for low tide.

Let's try t = 6 which means 6 a.m

Thus;

y = 20 + 5 cos (π(6)/6)

y = 20 + 5 cos π

Cos π has a value of -1

Thus;

y = 20 + 5(-1)

y = 20 - 5

y = 15 ft

Thus;

Low tide occurs at 6 a.m and 6 p.m

A vacuum cleaner costs $68, and the full-replacement extended warranty costs $22. if the manufacturer sells 360,920 vacuum clean
olasank [31]

The cost of the 15 percent of replaced vacuum cleaner which are sold under warranty is $3,681,384. Option b is correct.

<h3>What is percentage ?</h3>

Percentage of a number is the part of the number expressed in the in every hundred. Percentage of a number is expressed with the symbol '%'.

A vacuum cleaner costs $68, and the full-replacement extended warranty costs $22.

The manufacturer sells 360,920 vacuum cleaners under warranty and must replace 15% of them to honor the warranties. Thus, the number of vecuum cleaner replaced by manufacturer is,

n=\dfrac{15}{100}\times360,920\\n=54138

The cost of one vacuum cleaner is $68. Thus the cost of 54138 vcacuum cleaner is,

C=54138\times68\\C=3681384

Hence, the cost of the 15 percent of replaced vacuum cleaner which are sold under warranty is $3,681,384. Option b is correct.
