Ricky buys remote control cars to resell. He applies a markup of 18%. If Ricky buys a remote control car for $26.00, what is his selling price

The correct answer is 4.8 hours

Explanation:

This mathematical problem can be solved by using the rule of three, which involves finding an unknown value by using three related values. The process is shown below:

1. It is known a fully charged battery (100% battery) lasts 16 hours. This can be represented as 100 = 16. But it is not know how much a 30% battery last; this can be represented as 30 = x.

2. Write all the values

100 = 16

30 = x

3. Cross multiply to create an equation and solve the equation

100 x = 48

x = 480 / 100

x = 4.8

Answer:

The points on the perpendicular bisector of a side of a triangle are equidistant from the vertices of the side it bisects.

Step-by-step explanation:

It is the last option. The perpendicular bisector theorem states that if  a point lies on  the bisector of a segment it is equidistant from the endpoints.

Meaning

If a perpendicular bisector is a line of the side of the triangle , it bisects the sides forming two right angles .

The first three choices are incorrect because

1) the figure shows a triangle bisected into two triangles and option 1 tells about 1 isosceles triangle.

2) The base angles of any triangle can be different or same .

3) the three perpendicular bisectors meet at a point called the circumeter. We have 1 perpendicual bisector which is dividing the triangle into two equal triangles.

The statement that John can use the figure given to prove is that: D. The points on the perpendicular bisector (CD) of a side (AB) of a triangle (triangle ADB) are equidistant from the vertices (<A and <B) of the side it bisects.

Recall:

From the triangle in the image drawn by John, it means that since CD a perpendicular bisector of side AB, it means that the distance from point D to vertex A and the distance from point D to vertex B are equal.

[tex]1meter = 39.37inches \\ 8.104meters = (39.37 \times 8.104)inches \\ = 319.05448inches[/tex]

There are [tex]3.1496\cdot 10^6[/tex] inches in [tex]8\cdot 10^4[/tex] meter.

Important information:

Using the given information,

1 meter = 39.37 inches

Using this conversion, we get

[tex]8\cdot 10^4[/tex] meter = [tex]39.37\times (8\cdot 10^4)[/tex] inches

[tex]8\cdot 10^4[/tex] meter = [tex]39.37\times 80000[/tex] inches

[tex]8\cdot 10^4[/tex] meter = [tex]3149600[/tex] inches

[tex]8\cdot 10^4[/tex] meter = [tex]3.1496\cdot 10^6[/tex] inches

Answer:

Step-by-step explanation:

Step-by-step explanation:

Let ABC be a right angled triangle where there's a right angle in B . Let the measure of the angle BAC be ∅. So,

[tex] \sin(∅) = \frac{BC}{AC} [/tex]

[tex] = > {\sin}^{2}∅ = \frac{ {BC}^{2} }{ {AC}^{2} } [/tex]

Also,

[tex] \cos(∅) = \frac{AB}{AC} [/tex]

[tex] = > { \cos}^{2}∅ = \frac{ {AB}^{2} }{ {AC}^{2} } [/tex]

Now adding the values of sin^2∅& cos^2∅,

[tex] { \sin}^{2} ∅ + { \cos}^{2} ∅ = \frac{ {BC}^{2} }{ {AC}^{2} } + \frac{ {AB}^{2} }{ {AC}^{2} } [/tex]

[tex] = > { \sin}^{2} ∅ + { \cos}^{2} ∅ = \frac{ {AB}^{2} + {BC}^{2} }{ {AC}^{2} } [/tex]

But we know that

[tex] {AC}^{2} = {AB}^{2} + {BC}^{2} [/tex] by applying Pythagorean Theorem

So ,

[tex] = > { \sin}^{2} ∅ + { \cos}^{2} ∅ = \frac{ {AC}^{2} }{ {AC}^{2} } = 1[/tex]

Explanation:

This is the only point in the shaded region. The other points are either on the boundary line or outside the shaded region. Points on the boundary do not count because of the dashed line. The dashed line is due to no presence of an "or equal to" as part of the inequality sign.

See the diagram below.

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

A nonvisual approach will have you plug each of the coordinates into the given inequality.

For instance, choice A has x = 0 and y = 2 pair up which plug in to get

y < (-2/3)x + 2

2 < (-2/3)*0 + 2

2 < 2

which is false, so that's why choice A is not the answer. You should find that choices B and D are false too. Only choice C is true because

y < (-2/3)x + 2

0 < (-2/3)*0 + 2

0 < 2

which confirms the answer we got when we used the visual approach.

Answer:

The standard form of equation of the line through the given points. through (0.-4) and (-3,-2) is [tex]\frac{2}{3}x+y=-4[/tex]

Step-by-step explanation:

The standard form of equation is [tex]Ax+By=C[/tex]

Finding slope

Using the given points (0,-4) and (-3,-2) we can find slope using formula:[tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]Slope=\frac{-2-(-4)}{-3-(0)}\\Slope=\frac{-2+4}{-3} \\Slope=-\frac{2}{3}[/tex]

Finding y-intercept

Using point (0,4) and Slope=-2/3 we can find y-intercept

[tex]y=mx+b\\-4=-\frac{2}{3}(0)+b\\-4=0+b\\b=-4[/tex]

The slope intercept form of the line through the given points. through (0.-4) and (-3,-2) having slope =-2/3 and b=-4 will be:

[tex]y=mx+b\\y=-\frac{2}{3}x-4[/tex]

Now, standard form of equation will be: [tex]\frac{2}{3}x+y=-4[/tex]

So, The standard form of equation of the line through the given points. through (0.-4) and (-3,-2) is [tex]\frac{2}{3}x+y=-4[/tex]

Answer:

Okay

Step-by-step explanation:

Since it's a parallelogram, the adjacent angles on the same side is complimentary. Meaning they add up to get 180°.

So,

12x° + 8x° = 180°

20x°= 180°

x°= 180/20

x°= 9°

Step-by-step explanation:

Answer:

75%

Step-by-step explanation:

We need to find out what your grade is.

Since we know that you got 15 out of 20 points we need to find the Greatest Common Factor of these two numbers.

1.  [tex]5\left \{ {{15 / 5} \atop {20 / 5 }} \right}} = \frac{3}{4}[/tex]

Now we need to turn this fraction into a decimal.

In order to do that we need to divide our 3 by our 4.

2.  [tex]\frac{3}{4} = .75[/tex]

Finally, we need to turn this decimal into a percentage.

In order to do this we must multiply our decimal by 100.

Explanation:

For any rectangle, the diagonals are always the same length. We can use congruent triangles to prove this.

This means AC = BD.

Also, the diagonals of a rectangle cut each other in half (bisect). This indicates the following two equations

We'll use that second equation along with BP = -2x+23 and DP = 3y-6 to form the equation -2x+23 = 3y-6. This will be used later.

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

By the segment addition postulate, we know that

BP+DP = BD

(-2x+23)+(3y-6) = BD

BD = -2x+3y+17

Since the diagonals are equal, we also know that AC = -2x+3y+17

We are given that AC = 2x+4

Equating the two right hand sides leads to the equation 2x+4 = -2x+3y+17

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

The conclusion of each the last two sections was the following two equations

We have two equations and two unknowns. We have enough info to be able to find x and y.

Let's isolate 3y in the first equation

-2x+23 = 3y-6

3y-6 = -2x+23

3y = -2x+23+6

3y = -2x+29

Then we can plug this into the second equation

2x+4 = -2x+3y+17

2x+4 = -2x+(3y)+17

2x+4 = -2x+(-2x+29)+17 .... replace 3y with -2x+29

Now solve for x

2x+4 = -2x+(-2x+29)+17

2x+4 = -2x-2x+29+17

2x+4 = -4x+46

2x+4x = 46-4

6x = 42

x = 42/6

x = 7

We then use this to find y

3y = -2x+29

3y = -2(7)+29

3y = -14+29

3y = 15

y = 15/3

y = 5

Answer:

I used the method of replacement on the sistem of equations.

The final answer I got was y=5
