A rectangle has a length of 17 less than 6 times it's width. If the area of the rectangle is 7585 square feet find the length of
anzhelika [568]

9514 1404 393

Answer:

  205 ft

Step-by-step explanation:

Let w represent the width of the rectangle. Then the length is (6w-17) and the area is ...

  A = LW

  7585 = (6w-17)(w)

  6w² -17w -7585 = 0

Perhaps most straightforward is using the quadratic formula to solve this.

For ax² +bx +c = 0, the solution is x = (-b±√(b²-4ac))/(2a). For the above quadratic, the solution is ...

  x=\dfrac{-(-17)\pm\sqrt{(-17)^2-4\cdot6\cdot(-7585)}}{2\cdot6}=\dfrac{17\pm\sqrt{182329}}{12}\\\\x=\dfrac{17\pm427}{12}=\{-34\frac{1}{6},37\}

The width is 37 feet, so the length is ...

  6(37) -17 = 205 . . . feet

The length of the rectangle is 205 feet.

PLEASE SOLVE THIS :(<br>​
Lesechka [4]

Answer:

10.5 %

<u>Skills needed: Financial Math Essentials</u>

Step-by-step explanation:

1) First, before getting started, let's assume the price of the product is x. This variable will be used a lot throughout the problem (x).

2) Marking a price above means increasing the price in order to make money off of the purchased product. When raising something by y percent, the new price would be x + \frac{y}{100}*x.

---> In this case, the price increased by \textbf{30} percent.

This means that it would be: x+\frac{30}{100}x = x+0.3x=1.3x

New price is: 1.3x

3) The shopkeeper is then offering a \textbf{15} percent discount off of this marked price. When offering a b percent discount price, the new price (with discount), expressed algebraically is: a-\frac{b}{100}a

---> the expression above simplifies to (1-\frac{b}{100})a

In this case, a=1.3x, b=15

---> (1-\frac{15}{100})*1.3x = (1-0.15)*1.3x=0.85*1.3x=1.105x

This means that x, with discount, has been raised \textbf{10.5 percent}.

10.5 % is the profit percent

(The profit percent being the final marked up price - purchased price)

Which equation could generate the curve in the graph below
Setler79 [48]
The curve has been attached and the answer choices are:

y = 3x² – 2x + 1

y = 3x² – 6x + 3

y = 3x²<span> – 7x + 1
</span>
The attached graph has a vertex in the first quadrant. Therefore, the coordinates of the vertex would be both positive.

Let's start with first equation:

                                               y = 3x² – 2x + 1

using the equation of axis:
                                            x = -b/2a
                                            x = 2/6
                                            x = 1/3
SUbstituting the value of x in the main equation to get the y-coordinate of the vertex.
                                               y = 3(1/3)² – 2(1/3) + 1
                                               y = 3/9 – 2/3 + 1
                                               y = 1/3 – 2/3 + 1
                                               y = (1 - 2 + 3)/3
                                               y = 2/3

Hence, the vertex would be:
                                             (h,k) = (1/3 , 2/3)

Also, the leading coefficient is positive, so the parabola would be concave up.

Thus the final answer choice will be:

                                             y = 3x² – 2x + 1

What is the solution of 4x - 30 ≥ -3x + 12?
amid [387]
First, let's add 30 to both sides:
4x - 30 +30 ≥ -3x + 12+30


4x ≥ -3x + 42

Now, let's add 3x to both sides
4x +3x ≥ -3x+3x + 42
7x ≥ 42

Let's divide both by 7:

x ≥ 6
