What is the area of this shape?

Answers

The area of the composite shape in the image given is calculated as: 316 yd²

How to Find the Area of a Composite Shape?

To find the area of a composite shape, find the area of each of the shape that makes up the figure, then add their areas together.

The area of the composite shape = area of big rectangle + area of small rectangle + area of big triangle + area of small triangle

Area of big rectangle = (length)(width) = (5 + 4)(8) = 72 yd²

Area of small rectangle = (length)(width) = (5)(4) = 20 yd²

Area of big triangle = 1/2(base)(height) = 1/2(12)(4+5+4+7) = 120 yd²

Area of small triangle = 1/2(base)(height) = 1/2(8+5)(16) = 104 yd²

The area of the composite shape = 72 + 20 + 120 + 104 = 316 yd²

Answers

The sum of the first thirteen terms of the geometric series is -7971615.

What is Geometric series?

This is the sum of an infinite number of terms that has a constant ratio between successive terms.

To calculate the sum of the first thirteen terms of the geometric series, we use the formula below.

Formula:

S₁₃ = a(rⁿ-1)/(r-1).............. Equation 1

Where:

S₁₃ = Sum of the first thirteen terms of the geometric series.a = First term of the seriesr = Common ratio

Given:

a = -10r = 3n = 13

Substitute these values into equation 1

S₁₃ = -10(3¹³-1)/(3-1)S₁₃ = -7971615

Hence, the sum of the first thirteen terms of the geometric series is -7971615.

Step-by-Step Explanation:

70D + 6 - 9D = 35 + 4D - 2
70D + 6 - 9D - 4D = 35 - 2
70D - 9D - 4D = 35 - 2 - 6

What is the perimeter of rhombus ABCD?
10 units
20 units
2√7 units
4√7 units

Answers

Answer:

The perimeter of the rhombus is 20 units

Step-by-step explanation:

One important fact about a rhombus is that all four of its sides are equal, so we only need to solve for one side in order to find the perimeter. We can use the Pythagorean Theorem to solve the side length of the rhombus. Using line AD as a reference, we know that the length of AD is the square root of the change in x squared plus the change in y squared, or [tex]\sqrt{3^{2}+4^{2} } =\sqrt{9+16} =\sqrt{25}=5[/tex] units. Multiply the length of AD by 4 and you'll get that the perimeter of rhombus ABCD is 5 × 4 = 20 un.

The perimeter of the rhombus ABCD is 20 units.

Option B is the correct answer.

What is a rhombus?

A rhombus is a quadrilateral that has four equal sides.

Some of the properties we need to know are:

- The opposite sides are parallel to each other.

- The opposite angles are equal.

- The adjacent angles add upto 180 degrees.

We have,

We can use the distance formula to find the length of each side of the rhombus, and then add them up to find the perimeter.

The distance between points A and B is:

[tex]AB = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}\\= \sqrt{(-2 - 1)^2 + (-3 - 1)^2}\\ = \sqrt{9 + 16}\\= \sqrt(25) \\= 5[/tex]

The distance between points B and C is:

[tex]BC = \sqrt{(x2 - x1)^2 + (y2 - y1)^2}\\= \sqrt{(-5 - (-2))^2 + (1 - (-3))^2}\\ = \sqrt{9 + 16}\\= \sqrt{25}\\= 5[/tex]

The distance between points C and D is:

[tex]CD = \sqrt{(x2 - x1)^2 + (y2 - y1)^2}\\ = \sqrt{(-2 - (-5))^2 + (5 - 1)^2}\\ = \sqrt{9 + 16}\\ = \sqrt{25}\\ = 5[/tex]

The distance between points D and A is:

[tex]DA = \sqrt{(x2 - x1)^2 + (y2 - y1)^2}\\ = \sqrt{(1 - (-2))^2 + (1 - 5)^2}\\ = \sqrt{9 + 16}\\= \sqrt{25}\\ = 5[/tex]

Since a rhombus has all sides of equal length, we can add up the lengths of the sides to find the perimeter:

P = AB + BC + CD + DA = 5 + 5 + 5 + 5 = 20

Therefore,

The perimeter of the rhombus ABCD is 20 units.

The sum of Two numbers is 9. The

41. Find the numbers.

Answers

Answer:

4 and 5

Step-by-step explanation:

Assuming your 2nd sentence should be: "The sum of the squares of the two numbers is 41"

X + Y = 9   {equation 1}

X² + Y² = 41  {equation 2}

from equation 1:  y = 9-x

Substitute that into equation 2

x² + (9-x)² = 41

x² + 81 - 18x + x²= 41

2x² - 18x + 40 = 0

We can factor out a 2

x² - 9x + 20 = 0

(x-5)(x-4) = 0

x = 5 or 4

checking

Your two numbers are 4 and 5

For part 5 the total value is $1845, for part 6 the total net worth is $3200, and for part 7 the debt to assets value is 0.433.

What is debt?

It is defined as the amount one party needs to pay to another party as the first party borrowed an amount that will be credited by the second party. Debt occurs when one party cannot be able to purchase something under normal circumstances.

5)

Total value = 20×30 + 18×40 + 35×15 = $1845

6)

Net worth = (3500 + 300 + 600) - (1000+200) = $3200

7)

Total debt value = 2000+3200 = $5200

Total assets value = 10000+1300+700 = $12000

Debt to assets value = 5200/12000 = 0.433

Similarly, we can find any debt to assets value by using the formula:

Debt to assets value = Total debt/Total assets

Thus, for part 5 the total value is $1845, for part 6 the total net worth is $3200, and for part 7 the debt to assets value is 0.433.

f + f + 68° = 180°

Solving this gets f = 56°

Bottom Image:

  We know that the sum of the angles will add up to 180 and that the angles of the triangle are 23°, 23°, and g. Therefore, we can set up the following equation:

You purchase a hat for $50. There is a sales tax of 8.5%. What is the final cost with sales tax?

Answers

50 x 1.085 = 54.25

Answer: Final cost w/ tax is $54.25

Answer:

Price before tax: $ 50.00

+ Sales tax (8.5%): $ 4.25

Total price including tax: $ 54.25

Step-by-step explanation:

A sales tax is a tax that is levied on the purchase of goods and services. Except for Alaska, Delaware, Montana, New Hampshire, and Oregon, all states in the United States and the District of Columbia charge a state sales tax when you buy goods or pay for services. Alaska, like many other states, allows local governments to levy local sales taxes. Certain kinds of goods are exempt from sales tax in some states. In Massachusetts, for example, there is no sales tax on ordinary supermarket goods. There are also extra tax surcharges in several states. Restaurants and motels in the hospitality business sometimes levy a tax rate greater than the state sales tax rate. Expected sales tax rates and potential tax surcharge rates should be checked with your state and area.

Sales Tax Calculation Formulas

How many pounds of walnuts that cost $0.80 per pound must be mixed
with 8 pounds of cashews that costs $1.25 per pound to make a mixture of
nuts that costs $1.00 per pound?

Answers

Answer:

The number of walnut pounds we need to add is 10

Step-by-step explanation:

We need to make a mixture that costs $1 per pound.

That means that the total cost of our mixture, divided by the number of pounds must be equal to 1.

[tex]\frac{MixtureCost}{NumberOfPounds} = 1[/tex]

Well, we know that the total cost of our mixture is equal to the cost of the cashews + cost of walnuts.

[tex]MixtureCost = CashewsCost + WalnutsCost[/tex]

We also know that we'll buy 8 pounds of cashews that cost $1.25 each and some amount of pounds (which we'll call x) of walnuts that cost $0.80.

Knowing all of that, we can write this:

[tex]MixtureCost=8*1.25 + x*0.8[/tex]

If we make that multiplication, we have that

[tex]MixtureCost=10+x*0.8[/tex]

Now that we know the cost of our mixture, we just need to know the total number of pounds... But we already know that, don't we?

We know that there are 8 pounds of cashews and x pounds of walnuts, so here's what we can write:

[tex]NumberOfPounds=8+x[/tex]

Now, if we plug in the values we found in the first equation, here's what we have:

[tex]\frac{10+x*0.8}{8+x}=1[/tex]

The 8+x is dividing, so i'll pass it to the other side multiplying:

       [tex]10+0.8*x=x+8[/tex]

The 10 in the left side will go to the right side with a negative sign:

[tex]0.8x=x-2[/tex]

Now, if I pass the x from the right side to the left one changing signs:

[tex]0.8x-x=-2\\\\-0.2x=-2[/tex]

By changing signs from both sides, we have that:

[tex]0.2x = 2\\\\x = 10[/tex]

Therefore, the number of walnut pounds we need to add is 10

You would need to mix in 10 lbs of Walnuts in order for it to equal $1.00 per pound. We started off with 8 lbs of Cashews at $1.25 per lb, which is $10. Since walnuts cost $0.80 per lb, it would be $8.00 for 10 lbs of Walnuts, which would be in total 18 lbs for $18.00. To find the cost per lb we divide the weight by the total price, 18 lbs / $18.00 makes it a $1.00 per lb.
