Circle

Step-by-step explanation:

Circle is the set of all points. Circle is the set of all the points in a particular plane that are the same distance from a fixed point, which is the center of a circle.

Hope this helps!

Answer:

A set is just a collection of things with some common property. When we collect all points that share a property we can end up with a line, a surface or interesting things.Points can make a line

Answer:

[tex]\sqrt[4]{2}^{3}[/tex]

Step-by-step explanation:

Answer:

Yes. Both are graphing calculators. TI 83 has a black only screen while the TI 84 has a colored screen

Yes. The two calculators are the same more or less overall. They have the same functions and features. There are slight differences (eg: the TI84 is slightly faster than the 83 version), but it's not too big a deal since you can do the same math with both versions.

If you can, I recommend using online tools such as Desmos or GeoGebra. These tools are much faster compared to the TI83 and TI84. Also, they allow for multiple colors to be used, so you can tell the graphs apart. There are lots of other features as well (way too many to go over right now), and the best part is that both tools Desmos and GeoGebra are free. Unfortunately, your teacher may not allow you to use them in a test setting. However, I would ask and they may allow a limited version to be used in some capacity.

Answer:

9

Step-by-step explanation:

9 is 3/4*12.

That is a question about properties of rhombus.

There is a property of a rhombus that says that the its diagonals divided the internal angles in two equals angles.

Now that we know about it, it is easier to solve this question, because now we know that [tex]2x+39[/tex] and [tex]6x - 9[/tex] are equal angles. So, we can make a equation and solve it:

[tex]2x+39 = 6x - 9\\39 + 9 = 6x - 2x\\48 = 4x\\4x = 48\\x=\frac{48}{4} \\x=12[/tex]

Therefore, the value of [tex]x[/tex] is 12. So, the correct alternative is letter C).

I hope I've helped. ^^

Answer:

Jessica is 14 years old.

Step-by-step explanation:

Let [tex]o[/tex] equal Olivia's age, let [tex]j[/tex] equal Jessica's age, and let [tex]d[/tex] equal Daniel's age. With this lets write out what we know:

[tex]d = 7[/tex]

[tex]o = d + 2 = 7 + 2 = 9[/tex]

[tex]o = j - 8 + 3 = j - 5[/tex]

[tex]9 = j - 5[/tex]

[tex]j = 9 + 5 = 14[/tex]

Answer:

Yes he is over the speed limit.

Step-by-step explanation:

1 mile per minute * 60 minutes (1 hour) = 60 miles per hour

60 > 50

Since Angle QPS is a straight angle, it equals 180 degrees.

Angles QPR and RPS equal QPS.

Angle QPR + Angle RPS = QPS

(7x-4) + (9x-40) = 180

Answer:

Step-by-step explanation:

Answer:

CM = 16

MD = 16

CD = 32

Step-by-step explanation:

To find the value of x

3x + 1 = 8x - 24 (we know that M is the mid point so both of the lines will be equal)

Transpose

1 + 24 = 8x - 3x

25 = 5x

x = 25/5

x = 5

CM = 3x + 1

      = 3(5) + 1

      = 15 +1

     = 16

MD = 8x - 24

       = 8(5) - 24

       = 40 - 24

       = 16

CD = CM + MD

      = 16 + 16

      = 32

We have an algebra problem.

We will find that Hank's pickup needs 2 gallons of gas to travel 30 miles.

The information given is:

The pickup can travel 45 miles on 3 gallons of gas.

To find the number of miles that the pickup can travel per gallon of gas, we need to find the quotient between the amount that he travels (45 miles) and the amount of gas that he uses (3 gallons)

This is:

r = (45 miles)/(3 gallons) = 15 miles/gallon.

Now that we know this, the number of gallons needed to travel 30 miles is given by:

N = (30 miles)/(15 miles/gallon) = 2 gallons.

N = 2 gallons.

The pickup needs 2 gallons to travel 30 miles.
