Option A) 14/250 = N/350 is correct.

Kevin wants to change the engine in her car. The current engine is 250 cubic centimeters and has a 14 inch fan belt. The new engine is 350 cubic centimeters and has proportionally larger fan belt.

<h3>What is proportionality?</h3>

proportionality can be defined as, how much the number is relatable to other number i.e. x =2y x is two times proportion to y.

Hence, in the question
for 250 cc engine it has 14 inch belt
for 350 cc engine it has N inch belt(let)
proportionality can be given as
14 ∝ 250
N ∝ 350
dividing both equation
N/14=350/250
or 14/250=N/350

Thus, the required proportion is given as 14/250=N/350.

The area of a rectangle whose perimeter is a fixed 80 feet is given by A=40w - w2 , where w is the width of the rectangle. Deter
Stolb23 [73]

Answer:

Width=20 feet

Since Length=Width=20 feet, the rectangle is a Square.

Step-by-step explanation:

Area, A=40w - w^2

To determine the width of the rectangle that gives the maximum area, we take the derivative of A and solve for its critical point.

A'=40 - 2w\\$When A'=0\\40-2w=0\\40=2w\\w=20 feet

The width of the rectangle that gives the maximum area =20 feet.

Perimeter of a rectangle=2(l+w)

Perimeter of the rectangle=80 feet

2(l+w)=80

2l+2(20)=80

2l=80-40

2l=40

l=20 feet

Since the length and width are equal, the special type of rectangle that produces this maximum area is a Square.

Answer:


Step-by-step explanation:

<u><em>a specific shade of red nail polish requires 7 parts of red to 2 parts of yellow. A mixture contains 35 quarts of red and 8 quarts of yellow. </em></u>

<u><em>How can you fix the mixture to make the correct shade of red? </em></u>

<u><em>: </em></u>

<u><em>The red:yellow ratio is 7:2, we can write the mixture as 7%2F9 or 77.8% red </em></u>

<u><em>: </em></u>

<u><em>The existing mixture of 35:8 is a 43 quart mixture and can be written as: 35%2F43 or 81.4% red </em></u>

<u><em>: </em></u>

<u><em>we need to add yellow to reduce the per cent of red </em></u>

<u><em>: </em></u>

<u><em>Let y = amt of yellow required to do this </em></u>

<u><em>: </em></u>

<u><em> </em></u>

<u><em>  </em></u>

<u><em>7%2F9*(y+43) = 35 </em></u>

<u><em>Multiply both sides by 9 </em></u>

<u><em>7(y+43) = 9 * 35 </em></u>

<u><em>7y + 301 = 315 </em></u>

<u><em>7y = 315 - 301 </em></u>

<u><em>7y = 14 </em></u>

<u><em>y = 14/7  </em></u>

<u><em>y = 2 quarts of yellow to be added, for total mixture of 45 quarts </em></u>

<u><em>; </em></u>

<u><em>: </em></u>

<u><em>Check this, it still contains 35 quarts of red but the percentage has changed </em></u>

<u><em>35%2F45 = 77.8% red which is what we want, a ratio of 7:2</em></u>


<em>here you go i hope it helps</em>
