Answer:

Perimeter of the given patio is [tex](\pi+6)y + 10x +8[/tex].

Step-by-step explanation:

Let us first label the given patio using the points A, B, C, D, E and F as shown the attachment diagram.

Perimeter of given figure can be found by the following:  

Perimeter of polygon ABPCDEQF + Perimeter of semi-circle with diameter as EF.  

Let us mark points P and Q on sides AB and FA respectively.  

These points P and Q are just opposite to point D. Please refer to attached diagram for details.

As this figure has symmetry so, sides  

[tex]side\ AP =side\ FE\ i.e\ 2y\\side\ AQ =side\ BC\ i.e.\ 2y\\side\ PB =side\ CD\ i.e.\ 3x+5\\side\ QF =side\ DE\ i.e.\ 2x-1[/tex]

Perimeter of polygon APBCDEQF = AP + PB + BC + CD + DE + FQ + QA (Side EF is not on the periphery so it is excluded)

[tex]\Rightarrow 2y + (3x+5) + 2y + (3x+5) + (2x - 1) + (2x-1) + 2y\\\Rightarrow 6y + 10x + 8 ...... (1)[/tex]

Perimeter of semicircle = [tex]\pi \times radius[/tex]

Radius of semicircle is y.  

[tex]\text{Perimeter of semicircle = }\pi \times y ...... (2)[/tex]

Adding equations (1) and (2):  

[tex]\text{Total perimeter = }6y + 10x + 8 + \pi y \\\Rightarrow (\pi+6)y + 10x + 8[/tex]

Perimeter of the given figure is [tex](\pi+6)y + 10x +8[/tex]

Answer:

Mean = 141

Mode= 205

Step-by-step explanation:

Mean = all of the numbers added, then divided by the number of numbers there are.

120+205+90+205+85= 705

705 ÷ 5 = 141

The mode = the number that is repeated. 205 if the mode because it is the only number that is repeated.

Answer:

The surface area is 1,580.99 in²

Step-by-step explanation:

Known :

Diameter (d) = 19 in

Height (h) = 17 in

Asked :

Surface Area (Sa) = ...?

Answer :

Radius (r) = ½ d = ½ × 19 = [tex] \frac{19}{2} [/tex] = 9,5 cm

Tube Surface Area Formula :

= [tex] \boxed{\bold{\pi d (r + h)}} [/tex]

= 3.14 × 19 × (9,5 + 17)

= 59.66 × 26.5

= 1,580.99 in²

So, the surface area is 1,580.99 in²

I can't guarantee you that it's the good answer, but it's the best that I can do.

Answer:

to change a mixed number into an improper fraction, you just need to take the whole number in the problem and multiply it by the denominator and add it to the numerator.

To change an improper fraction into a mixed number you divide the numerator by the denominator and put the whole number you get in front of the left over fraction.

Step-by-step explanation:

Hello!

[tex]\boxed{ \bf The~marked~up~price~is~$30.}[/tex]The price will be $30.

To find the selling price, we must calculate 20% of $25 and add it to the price.

20% = 0.20

25 × 0.20 = 5

Add this number to the price of the item.

25 + 5 = 30

Answer:

$30

Step-by-step explanation:

$25 item

Markup = Increase

The $25 is increased by 20%

Write 20% as a decimal

Decimal = % / 100

20/100 = 0.2

Multiply 0.2 by 25

0.2(25) = 5

We know that the price that it was marked up is $5

Add this to the original amount ($25) to find the final price after being marked up.

$25 + $5 = $30

Answer:

0.80A + 0.92B = 63 .....1

A + B = 75 ......2

Step-by-step explanation:

Let A and B represent the total possible score in part A and B respectively;

Analysing each sentence of the question;

Sam scored 80% on Part A of a math test and 92% on part B of the math test. His total mark on the test was 63

80% of A + 92% of B = 63

0.80A + 0.92B = 63 ......1

The total possible marks for the test was 75;

A + B = 75 .....2

So, equation 1 and 2 provides a set of simultaneous equations that can be used to represent and solve the situation.

Solving the simultaneous equations, we will arrive at;

Part A = 50

Part B = 25

Answer:

[tex]V=8,448u^3[/tex]

Step-by-step explanation:

The volume of a prism is given by:

[tex]V=A_{b}*h[/tex]

where [tex]A_{b}[/tex] is the area of the base, and [tex]h[/tex]  is the height of thr prism.

We know that the height is:

[tex]h=22[/tex]u

and the bases of this prism are hexagons.

Thus the area of the base is the area of a regular hexagon:

[tex]A_{b}=\frac{n*l*a}{2}[/tex]

where [tex]n[/tex] is the number of sides: for an hexagon: [tex]n=6[/tex]

[tex]l[/tex] is the length of each side: [tex]l=8[/tex]u,

and [tex]a[/tex] is the apothem: [tex]a=16u[/tex]

we substitute all of this to find the area of the base:

[tex]A_{b}=\frac{6*8u*16u}{2}\\ \\A_{b}=\frac{768u^2}{2}\\ \\A_{b}=384u^2[/tex]

and finally we use the formula for the volume:

[tex]V=A_{b}*h[/tex]

we get the following:

[tex]V=384u^2*22u\\V=8,448u^3[/tex]

which is the third option

If something isn't clear or you're still confused about, let me know in the comments.

Step-by-step explanation:

Okay, here's my best try.

Suppose you have a bill for $8.45

If you are asked to add, say, 8% tax, you must calculate 8 percent of 8.45 and then add it to 8.45.

Begin by converting 8% to decimals by dividing by 100.

[tex]\frac{8}{100}=0.08[/tex] 8% is 0.08 in decimal form.

To calculate a percentage of a number, you multiply the decimal percent by the number; example:

[tex]0.08(8.45)[/tex] 8.45 is being multiplied by 0.08. The result is: 0.676. (this is the tax; however you have to round up to two decimal places: $0.68)

After finding the tax amount, if you are asked to add it to the bill, you have to add it to the original bill; in this case, $8.45

This would be: 0.68+8.45=9.13.

Therefore, the total bill after tax is for $9.13

----------------------------------------------------------------------------------------------------

With tips is the same thing, however, you can have 2 situations.

Situation 1: You are asked to calculate 15% tip of total bill.

In this situation, you can do the same we do to calculate tax.

Convert the percentage to decimal by dividing by 100.

[tex]\frac{15}{100}=0.15[/tex]

and multiply it by the original bill.

[tex]0.15(8.45)=1.2675[/tex]. Rounding up, this would be $1.27 for tip.

If you were to add it to the original bill, simply sum.

[tex]8.45+1.27=9.72[/tex]

The total bill after tips is for $9.72

Situation 2: You are asked to calculate 15% tip of the total bill with a tax of 8% included.

In this situation, you must first calculate the total bill with the tax added, like we did above; we got a bill for $9.13 (Tax included)

Then you can calculate 15% tip of this new bill that has tax included.

Convert

[tex]\frac{15}{100}=0.15[/tex]

Multiply by the new bill (because this is the one that includes tax)

[tex]0.15(9.13)=1.3695[/tex] Round up.... $1.37 for tips.

If you are asked to give a total amount of money including tax and tips, add this to the bill.

9.13+1.37=10.50

This bill would be for $10.50

Answer:

Step-by-step explanation:

Given the expression

3x + 2 = 4x + 5

1. The smaller coefficient of x is 3

to remove the smaller coefficient

we need to add - 3x to both sides

3x +2 + (-3x) = 4x +5 (-3x)

3x + 2 - 3x = 4x + 5 - 3x

Collecting like terms we have

3x-3x+2= 4x-3x+5

2 = x+ 5

2. The constant on the right side is

5,to remove the constant from the right side of the equation we need to add - 5 to both sides

3x + 2+ (- 5) = 4x + 5 +(-5)

3x+ 2-5 =4x +5-5

3x-3 = 4x

Answer:

∠ABC = 100°

∠ADF = 100°

Step-by-step explanation:

(8x + 4)° = (10x - 20)°

(2x)° = 24°

x = 12°

Compute, knowing that x = 12°

8x + 4 = 8 · 12 + 4 = 100°

10x - 20 = 10 · 12 - 20 = 100°

Answer: 5.22kg

Step-by-step explanation:

From the question, a farmer sells 8.7 kilograms of pears and apples at the market. Of the pears and apples sold, 2/5 of this weight is pears, and the rest is apples. To calculate the kilograms of apple sold goes thus:

Total kilograms sold = 8.7kg

Fraction of pears weight = 2/5

Pears kilograms sold = 2/5 × 8.7

= 0.4 × 8.7

= 3.48kg

Since the kilograms of pears sold is , 3.48kg, to get the kilograms of apple sold, we subtract 3.48kg from 8.7kg. This will be:

= 8.7kg - 3.48kg

= 5.22kg

Answer:

42.50 = 8.50p

Solution of the equation : p = 5

The can buy 5 pizza.

Step-by-step explanation:

Given;

Total cost allocated for buying pizza C = $42.50

Cost of one pizza c = $8.50

Number of pizza they can buy = p

This can be expressed in an equation as;

Total cost = cost per pizza × number of pizza

C = pc

Substituting the values of C and c;

42.50 = 8.50p

We can solve the derived equation for p;

p = 42.50/8.50

p = 5
