Step-by-step explanation:

Answer:

side of the octagon = 46.38 mm

Perimeter of the octagon = 371.04 mm

Step-by-step explanation:

Area of octagon = 10,391.9 mm²

But, area of octagon is given by the formula = 2(1 + √2)side²

⇒ 2(1 + √2)side² = 10391.9

⇒ 4.83 × side² = 10391.9

⇒ side² = 2151.53

⇒ side of the octagon = 46.38 mm

Perimeter of the octagon = 8 × side

⇒ Perimeter of the octagon = 8 × 46.38

⇒ Perimeter of the octagon = 371.04 mm

The anwser is 73

95 artists 25 showed sculptures+ 48 that show paintings= 73 artists showed sculptures or paintings

Final answer:

By using the principle of inclusion-exclusion, we find that 61 artists showed only sculptures or paintings at the art fair.

Explanation:

To find out how many artists showed only sculptures or paintings, we use the principle of inclusion-exclusion in set theory. We start by adding the number of artists that showed sculptures and those that showed paintings:

Artists with sculptures + Artists with paintings = 25 + 48 = 73.

However, since some artists showed both, we must subtract the number of artists who showed both sculptures and paintings to avoid double-counting:

Artists who showed both = 12.

Now, we subtract this number from our previous total:

73 - 12 = 61 artists who showed only sculptures or paintings.

[tex]0.001y^{12}=(0.1)^3y^{4\cdot3}=(0.1)^3(y^4)^3=(0.1y^4)^3\\\\0.008b^6=(0.2)^3b^{2\cdot3}=(0.2)^3(b^2)^3=(0.2b^2)^3\\\\-\dfrac{2}{27}a^{15}=\left(-\dfrac{2}{3}\right)^3a^{5\cdot3}=\left(-\dfrac{2}{3}\right)^3(a^5)^3=\left(-\dfrac{2}{3}a^5\right)^3\\\\\text{Used:}\\\\(a^n)^m=a^{n\cdot m}\\\\(ab)^n=a^nb^n[/tex]

The expressions 0.001y^12, 0.008b^6 and -8/27a^15 can be written as the cubes of the monomials 0.1y^4, 0.2b^2 and -2/3a^5 respectively.

The expressions provided can be written as a cube of a monomial. A monomial is a single term, and the cube of a monomial is a term raised to the third power. First, let's begin by expressing the coefficients as cubes:

Then, for the variables, divide the exponent by 3:

Final answer:

The cosecant of the angle can be determined as the reciprocal of the sine value of the angle, which is √3/√5.

Explanation:

Calculating the cosecant of the angle:

To find the cosecant of the angle, we need to use the definition of cosecant which is the reciprocal of the sine function. Since the point (-2/3, √5/3) lies on the unit circle, the y-coordinate (√5/3) can be used as the sine value of the angle.

Therefore, the cosecant of the angle is the reciprocal of the sine value, which is 1/(√5/3) = √3/√5.

The answer of this one is 9-c

Answer: Choice C

The first inequality is [tex]124+121+x \ge 400[/tex]

The second inequality is [tex]x \ge 155[/tex]

Replace x with whatever letter your teacher is using

=========================================================

Let x be the number of cans collected on week 3

Add this to the previous totals (for weeks 1 and 2) to get 124 + 121 + x. I'm going to leave this as is and not simplify. This is so the answer matches up. This total must be greater than or equal to 400, meaning 124+121+x can be 400 or larger.

124+121+x >= 400

245+x >= 400 .... combine like terms

x >= 400-245 .... subtract 245 from both sides

x >= 155

So you need to collect at least 155 cans for the third week so that you'll have at least 400 cans total.

Step-by-step explanation:

The girl walked a distance of [tex]\boxed{{\mathbf{5 miles}}}[/tex]  in her way.

Further explanation:

The time can be calculated as,

[tex]{\text{ time}}=\frac{{{\text{distance}}}}{{{\text{speed}}}}[/tex]  

Given:

It is given that a girl stands 20 miles away from the school at [tex]6:50{\text{ am}}[/tex]  and she started walking at the rate of [tex]3{\text{ mi/hr}}[/tex]  and then after some time her dad pick up and he drives at the rate of [tex]30{\text{ mi/hr}}[/tex] . They reach the school at [tex]9:00{\text{ am}}[/tex] .

Step by step explanation:

Step 1:

Consider [tex]x[/tex]  as the distance she walked in her way.

The speed of the girl when she walked is [tex]3{\text{ mi/hr}}[/tex] .

Now use the formula of time to obtain the walk time.

[tex]\begin{gathered}{\text{ walktime}}=\frac{{{\text{distance walked}}}}{{{\text{walking speed}}}}\hfill\\{\text{ walktime}}=\frac{x}{3}\hfill\\\end{gathered}[/tex]

Since the total distance is [tex]20{\text{ miles}}[/tex] .

Then consider [tex]20-x[/tex]  as the distance driven by the car.

The driving speed is [tex]30{\text{ mi/hr}}[/tex] .

Now use the formula of time to obtain the drive time.

[tex]\begin{gathered}{\text{drive time}}=\frac{{{\text{distance travelled by car }}}}{{{\text{ speed of car}}}}\hfill\\{\text{drive time}}=\frac{{20-x}}{{30}} \hfill\\\end{gathered}[/tex]

Step 2:

Now we calculate the total time took by girl to reach the school.

  [tex]9:00-6:50={\text{2 hrs 10 min}}[/tex]

Now convert the timing into hours as,

[tex]\begin{aligned}2{\text{ hours 10 minutes}}&=2+\frac{{10}}{{60}}\\&=2\frac{1}{6}\\&=\frac{{13}}{6}{\text{ hrs}}\\\end{aligned}[/tex]

Step 3:

Total time is the sum of drive time and walk time.

The total time can be expressed as,

[tex]\frac{x}{3}+\frac{{20-x}}{{30}}=\frac{{13}}{6}[/tex]

Now solve the above equation by cross multiply method.

[tex]\begin{aligned}\frac{x}{3}+\frac{{20-x}}{{30}}&=\frac{{13}}{6}\hfill\\\frac{{10x+20-x}}{{30}}&=\frac{{13}}{6}\hfill\\\frac{{9x+20}}{{30}}&=\frac{{13}}{6}\hfill\\6\left({9x+20}\right)&=13\left({30}\right)\hfill\\\end{aligned}[/tex]

Now simplify the further equation.

[tex]\begin{aligned}6\left({9x+20}\right)&=13\left({30}\right)\hfill\\54x+120&=390\hfill\\54x&=390-120\hfill\\54x&=270\hfill\\\end{aligned}[/tex]

Simplify the further equation.

[tex]\begin{aligned}54x&=270\hfill\\x&=\frac{{270}}{{54}}\hfill\\x&=\frac{{45}}{9}\hfill\\x&=5\hfill\\\end{gathered}[/tex]

Therefore, the girl walked 5 miles.

Answer:

each shirt costs $22.95

Step-by-step explanation:

39.58 + 52.22 = 91.80

91.80/4= 22.95

To find the price of each shirt Caitlan bought, use an equation to solve for the cost per shirt, which is $3.16.

Equation: Let x be the price of each shirt. Caitlan spent $52.22 on 4 shirts, so 4x = $52.22. After deducting the store credit, her total spending was $52.22 - $39.58 = $12.64. Therefore, 4x = $12.64. Now, solve for x:

4x = $12.64
x = $12.64 / 4
x = $3.16

Therefore, the price of each shirt Caitlan bought was $3.16.

She saves $100.She saves 10% more.They want to know how much they will save after 6 months. Multiply 10% by 6months and you get 60%.Then you multiply the answer of .60 (60%) by 100 and you get 60. Lastly, since you wanna know how much you saved,subtract $100-60 and your final answer you get is that she saves $40.Hope that helped!

Step-by-step explanation:

the answer is 26

Answer:

45 units^2

Step-by-step explanation:

Think of this polygon as being the combination of a rectangle and a triangle. The rectangle is at the bottom. It has length 9 and width 2.

The triangle is above it. Its base is also 9 like the rectangle's length. The height of the triangle is the segment from point (2, -1) to (2, 4). The length of the height is 6.

Now use the area formulas for a rectangle and a triangle to find the two areas and add them,

Rectangle: A = LW

Triangle: A = bh/2

Total area = LW + bh/2

Total area = 9 * 2 + 9 * 6/2

Total area = 18 + 54/2

Total area = 18 + 27

Total area = 45 units^2

Answer:

-60 3/4m

Step-by-step explanation:

The diver first dives down 50 1/4m, which is represented by the -50 1/4m. He then descends another 10 1/2m down. So -50 1/4m - 10 1/2m.

-50-10=-60

-(1/4)-(1/2)= (1/4)+(1/2)

(1/4+1/2)=(2/8+4/8) you can only add with the same denominators.

=6/8 (simplifies down to 3/4)

Answer:

y=6x+1

Step-by-step explanation:

First you must find the slope of the two points...

[tex]\frac{4--3}{-23-19}[/tex] which then would equal 6

Then you take the slope and put into point-slope form

(y-y1)=m(x-x1)...take one of the points that is given and plug it into this formula.

so I used (-3,19).

(y-19)=6(x--3)

I would then get y-19=6x+18

Add 19 to both sides and you will get y=6x+1

Answer:

$4.06 of taxes is added on an item that costs $56.00 is the sales tax rate is 7.25%.

Step-by-step explanation:

You are looking for 7.25% of $56.00

7.25% is the same thing as 7.25/100, which is the same thing as 7.25 ÷ 100

7.25 ÷ 100 = 0.0725

The word "of" is the same thing as a multiplication sign (×).

SO, 7.25% of $56.00 = 0.0725 × 56

0.0725 × 56 = 4.06 ⇒ YOUR ANSWER

There you go! I really hope this helped, if there's anything just let me know! :)

The difference between per diaper price is $0.04

Step-by-step explanation:

Given:

56 diapers can be bought for $ 28

and

online 112 diapers for $ 52

TO find:

Better deal = ?

Per diaper save= ?

Solution:

Let the first type be x

Now for x

Price of 56 diapers are $ 28

Price of one diaper = [tex]\frac{28}{56}[/tex]

                                 =$0.5 / diaper

Now for online let it be represented by O

Price of 112 diapers are $52

Price of one diaper = [tex]\frac{52}{112}[/tex]

                                 =$0.46 / diaper

Price of one diaper from online is less then price of one diaper from we bought not online

Difference of per diaper price = 0.5 - 0.46

                                                  =$0.04

So buying diapers from online would be suitable
