Answer B:  (-9, -12)

Step-by-step explanation:

I like to approach this problem by finding the halfway points in the x-direction and the y-direction, separately.

x-direction:  find the average of -3 and -15, which is -18/2, or -9.  The x-coordinate of the midpoint is therefore -9.

y- direction:  find the average of -4 and -20, which is -12.

Thus, the midpoint is located at (-9, -12)   (Answer B)

Answer:

Set A is a subset of set B. It means that every element of set A should be present in set B.

Step-by-step explanation:

A ⊆ B

Set A is a subset of set B. It means that every element of set A should be present in set B.

i.e for all a ∈ A then a ∈ B

Example:

Let set A = {1,2,3}

and B = { 1,2,3,4,5,6}

then A ⊆ B because every element in set A {1,2,3} is also present in set B {1,2,3,4,5,6}

Answer:

The surface area is divided by 4.

Step-by-step explanation:

Surface area of a sphere is 4πr².

When the diameter is 28 the radius is 14. So: 4π(14)² = 784π

If you cut the diameter in half you get 14. The radius is now 7.

4π(7)² = 196π.

784/4 = 196 so divided by 4.

Step-by-step explanation:

120/230 = 12/23

121/231 = 11/21

122/232 = 61/116

123/233 -- not reducible

124/234 = 62/117

125/235 = 25/47

126/236 = 63/118

127/237 -- not reducible

128/238 = 64/119

129/239 -- not reducible

___

All even digits will make the fraction reducible, as will the digit 5. Then the digits we're not sure of are 1, 3, 7, 9. Appending 1 to the given numbers makes them divisible by 11, so that digit is included in our list.

Ending digits 3, 7, 9 result in fractions that are not reducible. (Numbers 127, 233, and 239 are prime numbers.)

Answer:

0,1,2,4,5,6,8

Step-by-step explanation:

The answer is:

There will be 15 graders attending the virtual field trip.

We know that there are 60 sixth graders taking an online math classes but only 25% are planning to attend the virtual field trip, so,  if we want to calculate how many sixth graders will be attending the virtual field trip, we need to calculate the 25% of the total sixth graders

Before solving, we need to convert the given percent number (25%) to a real number by dividing it by 100, so, solving we have:

[tex]\frac{25(percent)}{100}=0.25[/tex]

Now, calculating how many graders are 25% of the total graders, we have:

[tex]GradersAttending=TotalGraders*PercentOfGradersAttendingTheVirtualTrip[/tex]

[tex]GradersAttending=60graders*0.25=15graders[/tex]

So, we have that there will be 15 graders attending the virtual field trip.

Have a nice day!

Answer:

15

Step-by-step explanation:

To get 25% of 60, you need to divide 25 by 10, your answer should be 0.25, next, you multiply 0.25 by 60, the answer if 15, another way, is by multiplying 15 by 4, that would make 60. (Have a great day, hope this helps, please mark me brainliest if it does help, sorry for answering really late)

Answer: y = sqrt x

Explanation:

In order to draw the graph of this function you will need to identify some of the values.

If x=0, then y = sqrt 0.

If x=1, then y = sqrt 1.

If x=2, then y = sqrt 2.

(This repeats.. you get the idea)

Plot these points and draw a curve through them. Your answer should look just like the graph in your question.

Answer:

  D)  x² + (y − 2)² = 52

Step-by-step explanation:

The center of the circle is the midpoint of the diameter, so is the average of the end points:

  (h, k) = ((-6, 6) +(6, -2))/2 = (0, 4)/2 = (0, 2)

Then the distance between the center and an end point is the radius. It is found using the distance formula:

  r = √((x2 -x1)² +(y2 -y1)²) = √((-6 -0)² +(6 -2)²) = √(36 +16) = √52

Putting these values into the standard form equation for a circle ...

  (x -h)² +(y -k)² = r²

gives ...

  (x -0)² +(y -2)² = (√52)²

  x² +(y -2)² = 52 . . . . . matches choice D

x = [5]

y = [2]

What if you rotate a plane figure around a straight line called the axis? Well, in doing so, you will get what in mathematics is called a solid of revolution, which is a solid figure. In this case, we have a triangle with a side matching the axis and this side. The solid that result when rotating that triangle is a cone. The side that matches the axis is the height of the cone while the side perpendicular to the axis is the radius of the base of the cone. The rotation is performed by the hypotenuse of the triangle (a straight line) through the origin and by an angle of 360 degrees.

Just divide 9.48 by 12.

Answer:

C

Step-by-step explanation:

To find the inverse, let y = f(x) then rearrange making x the subject, that is

y = 5(x + 3)³ - 2 ( add 2 to both sides )

y + 2 = 5(x + 3)³ ( divide both sides by 5 )

(x + 3)³ = [tex]\frac{y+2}{5}[/tex]

Take the cube root of both sides

x + 3 = [tex]\sqrt[3]{\frac{y+2}{5} }[/tex]

Subtract 3 from both sides

x = [tex]\sqrt[3]{\frac{y+2}{5} }[/tex] - 3

Change y back into terms of x, so

[tex]f^{-1}[/tex] (x ) = [tex]\sqrt[3]{\frac{x+2}{5} }[/tex] - 3 → C

Answer: Random samples

Step-by-step explanation: Jorge could ask how many hours people spend on the internet each day and then multiply that number by 7 for each person.

The best method for Jorge to collect data about 8th graders' internet usage is to conduct a survey.

Design the Survey: Create a set of questions focused on the amount of time spent on the internet. For example, 'How many hours per day do you spend on the internet?'etc

Distribution: Distribute the survey to the target group, either through paper forms during school hours or digitally through email or school platforms.

Data Collection: Collect the responses. Ensure that anonymity is maintained to get honest answers.

Analysis: Compile the data and calculate the average time spent online by 8th graders. Use graphical representations like bar charts or pie charts to visualize the data.

Presentation: Present the findings in a written report or a digital presentation, detailing the average time spent and highlighting any noticeable trends or patterns.

By conducting a survey, Jorge can efficiently gather accurate and representative data about the internet usage habits of 8th graders.

Answer:

3.00p ≥ 135; p ≥ 45

Step-by-step explanation:

You sell each for $3 so 3(pastries sold or p).

You want to make AT LEAST 135 (you could make more but not less.)

so 3.00p ≥ 135.

To solve: divide 135 by 3.

p ≥ 45

Answer: [tex]3p\geq135[/tex]  ; [tex]p\geq45[/tex]

Step-by-step explanation:

Given : The French club is sponsoring a bake sale. If their goal is to raise at least $135 (greater than of equal to $135).

Let p be the number of pastries they sell.

If  they sell at $3.00 each in order to meet that goal, then the total price of p pastries will be : 3p

Then, the inequality for the given statement will become:-

[tex]3p\geq135[/tex]

Divide both sides by 3 , we get

[tex]p\geq45[/tex]

Hence, they must sell 45 or more pastries to raise at least $135.

[tex]r=\frac{1}{3+2cos\theta}[/tex]

Step-by-step explanation:

Let us write the equations in standard form:

[tex]r=\frac{1}{3+2cos\theta} \implies r=\frac{\frac{1}{3} }{1+\frac{2}{3}\cos \theta }[/tex]

We have

[tex]e=\frac{2}{3}\:<\:1[/tex] and

 [tex]ep=\frac{1}{3}[/tex]

Since the eccentricity  of this conic is less than 1, the conic represents an ellipse.

The second equation is [tex]r=\frac{3}{2+3\sin \theta}[/tex].

This is a hyperbola, because eccentricity is more than 1.

The third equation is [tex]r=\frac{5}{2+2\sin \theta}[/tex].

This is a parabola, because eccentricity is  1.

The fourth equation is [tex]r=\frac{2}{2-3\sin \theta}[/tex].

This is also a hyperbola, because eccentricity is more than 1.
