Answer:

I believe it it 13 miles per hour.

Step-by-step explanation:

       We know that an object travels 270 miles, so the rate is 270 miles.

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

                                                      6 hours

1 mile = 5,280 feet                                            1 day = 24 hours

5,280 x 270 = 425,600                                    1 hour = 3600 seconds

270 miles = 425,600 feet                                 3600 x 6 = 21,600

                                                                           3600 x 24 = 86,400

  Fraction:                                                                  Fraction:

425,600 feet        4,256 ft                                      21,600 sec           1

     -------          =       -----                                             ------------   =     --------  hour

 5,280 feet            528 ft                                        86,400 sec           4

4,256/528 ÷ 1/4 = 4,256/528 x 4/1 (reciprocal) = 17,024/528 = 439/33 = 13

Hope this helps! :)

Answer:

$65

Step-by-step explanation:

Let

x = original price of the item

Mai buys one item and saves $13,

This means 20% of the original price of the item = $13

20% of x = 13

20/100 * x = 13

0.2 * x = 13

0.2x = 13

Divide both sides by 0.2

x = 13 / 0.2

= 65

x = $65

Therefore, the original price of the item is $65

Step-by-step explanation:

2^5/4=2^5/2^a=2^b=c

32/4=2^5/2^a=2^b=c

8=2^5/2^a=2^b=c

8=32/2^a=2^b=c

8=32/2a=2^b=c

8=16a=2^b=c

8=16a=2b=c

Answer:

0.243

Step-by-step explanation:

Given that :

Probability of success (p) = 76% = 0.76

Number of free throws (n) = 10

Probability of making 7 free throws = r

Using binomial distribution :

nCr * p^r * (1 - p)^(n-r)

10C7 * 0.76^7 * (1 - 0.76)^(10 - 7)

10C7 * 0.76^7 * 0.24^3

120 * 0.14645 * 0.013824

= 0.24294

Hence probability of making 7 free throws from 10 is 0.243

Answer:

  p = 3x+10

Step-by-step explanation:

The attached diagram pretty much explains it.

The unknown dimension at the top was the subject of a previous problem. It is the difference in length between the two marked horizontal segments:

  (2x +15) -(x) = x +15 . . . . . length of unmarked solid horizontal line

Similarly, the length of the unmarked vertical line on the right is the difference between the marked vertical lines:

  (2x -5) -(x -5) = x . . . . . length of unmarked solid vertical line

__

The formula for the area of a rectangle is used to find the areas of the left-side and right-side rectangles. Respectively, those areas are ...

  left-side area = x(2x -5)

  right-side area = x(x +15)

Then the total area enclosed by the solid line is ...

  x(2x -5) +x(x +15) = x(2x -5 +x +15) = x(3x +10)

__

The area of the lot extension is the product of its dimensions:

  extension area = x·p

We want this to be the same as the area in the solid line, so ...

  x·p = x·(3x +10)

Dividing by the coefficient of p (which is x), we have ...

  p = 3x +10

Answer:

f(-2)=2

Step-by-step explanation:

Replace all x’s with -2’s.

Answer:

3x^3 - 2x^2

Step-by-step explanation:

This is the answer because for the equation 3x^3 - 2x^2, nothing further can be done to this equation since there are no like terms.

Answer:

y=60 x=16

Step-by-step explanation:

the triangles are identical so 92+y=3y-28 so solve that for y:

                                                     -y      +28

                                                  120=2y                                                                            .                                                  /2      /2

                                                  60 = y so y=60

and 6x+2=3x+50 and solve that for x: which gets x = 16

Then are you supposed to plug it in to the numerical equvilant to the angles and sides becuase if so:  B and E is 152, AC and DF are 98

Hope this helps and brainliest would be greatly appreciated! Thanks!

Answer:

Step-by-step explanation:

The measure of angle 1 is equal to the measure of angle 2, its proved by using the theorem angle of tangency using arc measure.

Let A be a point on a circle and B be the point where a tangent (passing through B and C) intersects the circle. Then, the angle of tangency ∠ABC is half of the measure of the arc AB formed on the same side.

Given that, Arc AB= Arc CD in circle P.

Here, Arc AB= 1/2 ×m∠1 ------(i)

Arc CD= 1/2 ×m∠2 ------(ii)

Equation (i) and (ii) are equal, we get

1/2 ×m∠1=1/2 ×m∠2

m∠1=m∠2

Hence, proved.

m = [tex]\frac{y2-y1}{x2-x1}[/tex]

Answer:

[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Step-by-step explanation:

[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

the 2 and 1 represent which number they are in a series of points. For example, if I were to have points (1,2) and (3,4)

4 would be [tex]y_2[/tex] meaning it is the second y value

2 would be [tex]y_1[/tex] meaning it's the first y value

Same goes for x

3 is [tex]x_2[/tex]

1 is [tex]x_1[/tex]

so the equation for slope is [tex]\frac{4-2}{3-1}[/tex], or 1

Answer:

[tex]f(x)=5x^2+25x-30[/tex]

Step-by-step explanation:

Quadratic Equation

If the roots of a quadratic equation are known, we can form the equation as follows:

[tex]f(x)=a(x-x_1)(x-x_2)[/tex]

where x1 and x2 are the known roots, and a is the leading coefficient.

We are given the roots as x1=1 and x2=-6, and the leading coefficient as a=5, thus:

[tex]f(x)=5(x-1)(x+6)[/tex]

Operating:

[tex]f(x)=5(x^2-x+6x-6)[/tex]

Simplifying:

[tex]f(x)=5(x^2+5x-6)[/tex]

Multiplying:

[tex]\mathbf{f(x)=5x^2+25x-30}[/tex]
