Huong spent half of her weekly allowance on candy. Earn more money her parents let her wash the car for six dollars. What is her weekly allowance if she ended with $14?

Answer:

The answer is below

Step-by-step explanation:

Given the cost as C(x) = x² + 4x - 40

a) Since the bracelets sell for $8 each, the revenue from x bracelets is given as:

Revenue = price for each bracelet × number of bracelet

Revenue = 8 × x = 8x

b) Profit (P) = Revenue - Cost

P(x) = 8x - [x² + 4x - 40]

P(x) = 8x - x² - 4x + 40

P(x) = -x² + 4x + 40

c) To maximize profit, the derivative of profit is equal to 0

Hence P'(x) = 0

-2x + 4 =0

2x = 4

x = 2

To maximize profit, the company should produce 2 bracelets

d) The maximum profit is:

P(2) = -(2²) + 4(2) + 40 = -4 + 8 + 40

P(2) = $44

The maximum profit is $44

To solve this inequality, you need to multiply both sides by -5.

When you multiply or divide both sides of an inequality by a negative number, you must flip the inequality symbol.

[tex]m = \frac{y - y}{x - x} = \frac{55 - 59}{10 - 0} = \frac{ - 4}{10} = - \frac{2}{5} [/tex]

[tex]y = - \frac{2}{5} x + b[/tex]

Since the line passes through the point (0,59), the coordinates of this point satisfies the equation of y;

[tex]59 = - \frac{2}{5} (0) + b[/tex]

[tex]b = 59[/tex]

Final answer:

While guessing and checking is one way to do this problem, I will show you how to do it algebraically.

Let one side be A

Let the other side be B

2(A+B)=16

A*B=15

First equation because the perimeter is 16 and the second because the area is 15. Now solve the system of equations

A+B=8

A=8-B

Substitute into equation two

B(8-B)=15

-B^2+8b-15=0

B^2-8b+15=0

(B+3)(B+5)=0

B=3,5

A=5,3 respectively

From this we can see that one side is 5 meters long while the other side is three meters long.

Step-by-step explanation

Since we're looking at a rectangle, let's consider its perimeter and area formulas.

Perimeter: 2x + 2y (A rectangle has four sides, with two equal sides, so this is x + x + y + y simplified)

Area: (x)(y) (length x breadth so, x times y)

So we have two equations: 2x + 2y = 16 and x*y = 15. Solve simultaneously. Refer to the attached image.

Answer:

15

Step-by-step explanation:

The cards have 5 possible outcomes and the spinner has 3 possible outcomes. To find the sample size, you need to calculate the number of possibilities when drawing 1 card and landing on 1 side of the spinner. You can do this by multiplying the possible outcomes together.

5×3 = 15

Therefore, the sample size is 15.

Answer:

Option 1: 15

Step-by-step explanation:

Ricky is playing a game using 5 cards and a spinner

Card 1 , Card 2 , Card 3 , Card 4 , Card 5

and

㉦ Green, Red, Blue

Ricky picks a card and spins the spinner

The sample size outcome is:

{(1, G) (1, R) (1, B) (2, G) (2, R) (2, B) (3, G) (3, R) (3, B) (4, G) (4, R) (4, B) (5, G) (5, R) (5, B)}

Sample size is 15

Hey there!

1/5 + 3/10
= 2/10 + 3/10

= 2 + 3/10 - 0

= 5/10

= 5 ÷ 5 / 10 ÷ 5

= 1 / 2

Therefore, your answer is: 1/2

The positive solution of the quadratic equation [tex]\rm 0=-x^2+2x+1[/tex]  is x=2.41

It is given that the quadratic equation:

[tex]\rm 0=-x^2+2x+1[/tex]

It is required to find the solution to the above quadratic equation.

A quadratic equation is a second-degree algebraic equation represented by the:

[tex]\rm ax^2+bx+c=0[/tex]........(1)

Where a, b, and c are the constants and [tex]\rm a\neq 0[/tex]

We know that:

[tex]\rm x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

We have:

[tex]\rm 0=-x^2+2x+1\\\rm or \\\rm -x^2+2x+1=0[/tex] ..........(2)

After comparing (1) and (2) we get:

[tex]\rm a=-1, b=2, and \ c=1[/tex]

Put these values in the above formula we get:

[tex]\rm x=\frac{-2\pm \sqrt{2^2-(4)(-1)(1)}}{(2)(-1)}\\\rm x=\frac{-2\pm \sqrt{8}}{-2}\\\rm x=\frac{-2\pm 2\sqrt{2 }}{-2}\\\rm x={1\pm \sqrt{2}}[/tex]

[tex]\rm x=1+\sqrt{2} \ or \ x=1-\sqrt{2} \\\\\sqrt{2} = 1.41\\\rm so \ x= 1+1.41 \ or \ x= 1-1.41\\\rm x=2.41 or \ x=-0.41[/tex]

Thus, the positive solution of the quadratic equation is x=2.41

The length of the longer side of the rectangle will be 8.78 cm.

The area of a two - dimensional figure is the area that its perimeter encloses. The quantity of unit squares that occupy a closed figure's surface is its region.

On one of a rectangle's shorter sides, a semicircle is drawn. The rectangle's shorter side is 4 cm long. The figure has a surface area of 41.4 square centimeters.

Then the length of the rectangle is calculated as,

A = πr² / 2 + l × b

41.4 = (3.14 / 2) × (4/2)² + 4l

41.4 = 6.28 + 4

l = 8.78 cm

The length of the longer side of the rectangle will be 8.78 cm.

Answer:3/2

Step-by-step explanation:

d = rt

d/r  rt/r

d/r = t

Step-by-step explanation:

Equation for the volume of a cone is

V = (pi(r^2)h)/2

Plug in the known values to get

350 = (pi(6^2)h)/2

To find h, just isolate it by first dividing both sides by 2 and squaring 6 to get

175 = pi(36)h

Then, divide both sides by pi36 to get

h = 175/pi(36)

X= -3 or X=-9

Step-by-step explanation:

Answer: x = -3, x = -9

Step-by-step explanation: |x + 6| + 10 = 13

Firstly, subtract 10 from both sides:

|x + 6| = 3

Since it is an absolute value, separate it into two equations with either outcome:

x + 6 = 3

x + 6 = -3

Solve for x now.

x + 6 = 3

Subtract 6 from both sides:

x = -3

x + 6 = -3

Subtract 6 from both sides:

x = -9
