Answer:

  24 cm²

Step-by-step explanation:

The rectangular section on the right is 8 - 4 = 4 cm wide.

It is 3 + 1.5 = 4.5 cm tall.

The area of the rectangular section is ...

  A = LW

  A = (4.5 cm)(4 cm) = 18 cm²

__

The triangular section on the left is 4 cm wide and 3 cm high. Its area is ...

  A = 1/2bh

  A = 1/2(4 cm)(3 cm) = 6 cm²

The total shaded area is the sum of the areas of the triangular section and the rectangular section:

  area = 18 cm² +6 cm² = 24 cm² . . . area of the figure

Answer:

Hey there!

When we are given what one of our variables is equal to, we can easily solve the system of equations via substitution, which is where we take the variable value, plug it into the other equation, and solve for the other variable.

In this case, we just take our value for y and plug it in for the value for y in the first equation and solve for x.

2(-x+7)=14-2x

-2x+14=14-2x

-2x=-2x

x=x

As we can see, there are infinitely many solutions to this first equation, which means that there is no possible way to solve for y because x has infinitely many solutions, so there are infinitely many solutions to this system of equations, because they are both the same line.

I hope this helps! :D

Let's create an equation:

y is squared.

[tex] {y}^{2} [/tex]

Then, added to twice the same number.

[tex] {y}^{2} + {y}^{4} [/tex]

Lastly, minus by 74.

[tex] {y}^{2} + {y}^{4} - 74[/tex]

Unit price per ounce of the candy of 340.23 grams is $1.58

Ounce and gram are two different unit of mass and relation between them is 1 gram = 0.03527 ounces .

In the question it is given that  weight of candy is 340.23 grams

And it costs $18.99

Now we can covert grams to ounces as

[tex]1 \text{gram}= \ 0.03527 \text{ounces}\\[/tex]

Hence

[tex]340.23 \text{gram}= \ 340.23\times 0.03527 \text{ounces}\\\\\\340.23 \text{gram}=11.99 \ \text{ounces}\\[/tex]

Now 11.99 ounces of candy cost $18.99

So 1 ounce of candy cost 18.99/11.99= $1.58

Unit price per ounce of the candy of 340.23 grams is $1.58

The area of the rhombus is 24.7 square inches

Start by calculating the length BO using the following Pythagoras theorem

[tex]BC^2 = AO^2 + BO^2[/tex]

So, we have:

[tex]5^2 = 3.8^2 + BO^2[/tex]

Evaluate the exponents

[tex]25 = 14.44 + BO^2[/tex]

Collect like terms

[tex]BO^2 = 25 - 14.44[/tex]

[tex]BO^2 = 10.56[/tex]

Take the square roots

[tex]BO = 3.25[/tex]

The area of the rhombus is then calculated as:

[tex]Area = \frac{2BO * 2AO}{2}[/tex]

This gives

[tex]Area = \frac{2 * 3.25 * 2 * 3.8}{2}[/tex]

[tex]Area = 24.7[/tex]

Hence, the area of the rhombus is 24.7 square inches

Answer:

2nd Option 68 :)

Step-by-step explanation:

Explanation:

The mixed number 8 & 4/5 consists of the whole part 8 and the fractional part 4/5.

Divide the whole part 8 into 4 equal pieces

8/4 = 2

This means 2 is part of the final answer.

Also, divide the 4/5 into 4 equal pieces as well. This is the same as multiplying by 1/4

(1/4)*(4/5) = 1/5

Overall, the size of each section is 2 & 1/5 acres

To find the average divide total caught by total hours:

A) [tex]\frac{d^2y}{dx^2}=\frac{2y}{x^2}[/tex]

Step-by-step explanation:

Use implicit differentiation to find dy/dx

[tex]x^2y^2=1\\\\\frac{d}{dx}(x^2y^2)=\frac{d}{dx}(1)\\ \\x^2(\frac{d}{dx}y^2)+(\frac{d}{dx}(x^2))y^2 =0\\\\2yx^2\frac{dy}{dx}+2xy^2=0\\\\2xy(x\frac{dy}{dx}+y)=0\\ \\x\frac{dy}{dx}+y=0\\ \\x\frac{dy}{dx}=-y\\ \\\frac{dy}{dx}=-\frac{y}{x}[/tex]

Determine d²y/dx² using dy/dx

[tex]\frac{dy}{dx}=\frac{-y}{x}\\ \\ \frac{d^2y}{dx^2}=\frac{(x)[\frac{d}{dx}(-y)]-(-y)[\frac{d}{dx}(x)] }{x^2}\\ \\ \frac{d^2y}{dx^2}=\frac{-x\frac{dy}{dx}+y}{x^2}\\ \\ \frac{d^2y}{dx^2}=\frac{-x(\frac{-y}{x})+y}{x^2}\\\\ \frac{d^2y}{dx^2}=\frac{-(-y)+y}{x^2}\\\\ \frac{d^2y}{dx^2}=\frac{y+y}{x^2}\\\\ \frac{d^2y}{dx^2}=\frac{2y}{x^2}[/tex]

The profit on the shares is $2180

From the question, we have the following parameters that can be used in our computation:

Number of shares = 50

Cost price = $98.40

Current price = $142.00

The profit on the shares is then calculated as

Profit = (Current price - Cost price) * Number of shares

Substitute the known values in the above equation, so, we have the following representation

Profit = (142 - 98.40) * 50

Evaluate

Profit = 2180

Hence, the profit is $2180
