1) arc JL = 127°

arc JML = 233°

3) arc DE = 104°

arc FE = 76°

arc DEF = 180°

arc CFD = 284°

arc DFE = 256°

Step-by-step explanation:

1) arc JL = 127°

arc JML = 360 - 127 = 233°

3) arc DE =104°

arc FE = 180 - 104 = 76°

arc DEF = 180°

arc CFD = 180 + 104 = 284°

arc DFE = 360 - 104 = 256°

The angles arc measures are,

1) arc JL = 127°

arc JML = 233°

3) arc DE = 104°

arc FE = 76°

arc DEF = 180°

arc CFD = 284°

arc DFE = 256°

An angle of a circle is an angle that is formed between the radii, chords, or tangents of a circle. We saw different types of angles in the Angles section, but in the case of a circle, there, basically, are four types of angles. These are central, inscribed, interior, and exterior angles.

1) arc JL = 127°

arc JML = 360 - 127 = 233°

3) arc DE =104°

arc FE = 180 - 104 = 76°

arc DEF = 180°

arc CFD = 180 + 104 = 284°

arc DFE = 360 - 104 = 256°

Answer:

24.7 feet

Step-by-step explanation:

Maria who is 6 feet tall stands 20 feet away from the base of a tree she looks up at the top of the tree at a 43° angle of elevation.

what is the approximate height of the tree rounded to the nearest 10th?

We solve the above question using the Trigonometric function of Tangent

tan θ = Opposite/Adjacent

θ = Angle of elevation

Adjacent = Distance from the base of the tree = 20 feet

Opposite => Height of the tree = x

θ = 43°

tan 43 = x/ 20 feet

x = tan 43 × 20 feet

x = 18.650301723 feet

Approximately = 18.7 feet

We are told in the question that Maria is 6 feet tall

Therefore, the height of the tree = Maria's height + Height

= 6 feet + 18.7 feet

= 24.7 feet

Answer:

A - 2 feet

Step-by-step explanation:

We know that the tank is a rectangular prism which means the volume is equal to length*width*depth

since the tank can hold 30 cubic feet of water, we can divide 30 by the given dimensions of the length and width to find the depth

30/5 = 6

6/3 = 2

therefore, the depth of the tank has to be 2 feet (A)

        Length x Width x Depth

From the question:

Volume of the rectangular prism = 30 cubic feet

Length of the rectangular prism = 5 feet

Width of the rectangular prism = 3 feet

Depth of the rectangular prism = ?

        Depth = Volume / (Length x Width)

Hence,

Depth = 30 cubic feet / 5 feet  x 3 feet

Depth = 30/ 15

Depth = 2 feet

The correct option is option A

Answer:

Step-by-step explanation:

We cannot assume independence for the employees sampled from location A.

It is not appropriate to use this formula for the standard deviation of

A. The samples are not independent of each other.

The entire group about whom you want to make conclusions is referred to as a population.

The particular group from which you will gather data is known as a sample. The sample size is always smaller than the population as a whole.

We cannot rely on the workers' sampled employees' independence.

Assuming independence based on the 10% condition requires at least 200 employees in the population with a sample size of 20, however, location A only has 125 employees.

Answer:

The surface area of the given pyramid is 112 [tex]inches^{2}[/tex].

Step-by-step explanation:

Base length of the pyramid = 4 inches

Area of the base = [tex]length^{2}[/tex]

                            = [tex]4^{2}[/tex]

                            = 16

Area of its base = 16 [tex]inches^{2}[/tex]

Area of one of its triangular surface = [tex]\frac{1}{2}[/tex] x base x height

                                 = [tex]\frac{1}{2}[/tex] x 4 x 12

                                 = 2 x 12

                                 = 24 [tex]inches^{2}[/tex]

Area of all its four triangular surfaces = 4 x 24

                                                       = 96 [tex]inches^{2}[/tex]

surface area of the pyramid = sum of areas of all its surfaces

                                               = 16 + 96

                                       = 112 [tex]inches^{2}[/tex]

The surface area of the given pyramid is 112 [tex]inches^{2}[/tex].

Answer:17

Step-by-step explanation:

so i think it would be 17 as 5 is equivlent  to 8.33 percent of 60 which is the total amount of kids and 8.33 percent of 250 is 20 but since i think ur school rounds that percentage it would 17 red shirts

The results are in the table​ of the 250 total T-shirts about should be red 17.

We have given that,

Mr. torres ordered 250 School t-shirts to sell in a school store the t-shirts come in blue-gray or red to know how many of each color to order Mr. Torres polled a random sample of students. the results are in the table​.

A simple random sample is a subset of a statistical population in which each member of the subset has an equal probability of being chosen.

So I think it would be 17 as 5 is equivalent to 8.33 percent of 60 which is the total amount of kids and 8.33 percent of 250 is 20 but since I think your school grounds that percentage it would be 17 red shirts.

Answer:

Since Darcie wants to crochet a minimum of 3 blankets and she crochets at a rate of 1/5 blanket per day, we can determine how many days she will need to crochet a minimum of 3 blankets following the next steps:

- Finding the number of days needed to crochet one (1) blanket:

\begin{gathered}1=\frac{1}{5}Crochet(Day)\\Crochet(Day)=5*1=5\end{gathered}

1=

5

1

Crochet(Day)

Crochet(Day)=5∗1=5

So, she can crochet 1 blanket every 5 days.

- Finding the number of days needed to crochet three (3) blankets:

If she needs 5 days to crochet 1 blanket, to crochet 3 blankets she will need 15 days because:

\begin{gathered}DaysNeeded=\frac{NumberOfBlankets}{Rate}\\\\DaysNeeded=\frac{3}{\frac{1}{5}}=3*5=15\end{gathered}

DaysNeeded=

Rate

NumberOfBlankets

DaysNeeded=

5

1

3

=3∗5=15

- Writing the inequality

If she has 60 days to crochet a minimum of 3 blankets but she can complete it in 15 days, she can skip crocheting 45 days because:

AvailableDays=60-RequiredDaysAvailableDays=60−RequiredDays

AvailableDays=60-15=45DaysAvailableDays=60−15=45Days

So, the inequality will be:

s\leq 45s≤45

The inequality means that she can skip crocheting a maximum of 45 days since she needs 15 days to crochet a minimum of 3 blankets.

Have a nice day!

Answer:

C . 4

Step-by-step explanation:

step 1 : -3 multiply with inside of the ( 7x-5 )

= -21x + 15

step 2 : then it will be 21x + 15 = 87 + 3x

step 3 : switch between the odds into like this

21x - 3x = 87 - 15

step 4 : subtract it all

18x = 72

step 5 : bring 18 to the other side

x = 72/18

step 6 : to find the ans of x is just calculate them

x = 72 ÷ 18

= 4

Or you can do like these ⬇️

-3 ( 7x - 15 ) = 87 + 3x

21x + 15 = 87 + 3x

21x - 3x = 87 - 15

18x = 72

x = 72/18 or 72÷18

x = 4

Answer:

This week sales = 26

Last week sales = 84

Step-by-step explanation:

Let this week sales = x

Sales last week = 6 + 3x

Sales last week + this week = 110

x + (6 + 3x) = 110

x + 6 + 3x = 110

6 + 4x = 110

4x = 110 - 6

4x = 104

x = 26

This week sales = 26

Last week sales = 6 + 3(26) = 84

Answer:

Infinitely many solutions

Step-by-step explanation:

=> -16x - 20y = 16 => - 4(4x + 5y) = 12

=> 4x + 5y = 12/(-4) => 4x + 5y = -3 .. (1)

=> 8x + 10y = - 6 => 2(4x + 5y) = - 6

=> 4x + 5y = -6/2 => 4x + 5y = - 3 ...(2)

Note that both the equations come out be same on simplification. It means, we are given with only 1 equation that is 4x + 5y = -3, and since there is nothing more about this, equation would give different values of y for infinitely many random values of x.

Thus,

Equation has infinitely many solutions.
