Answer: 390$

Explanation:

Lets say each drives 9 miles per gallon, and each costs 6.50

540 / 9 = 60

60 x 6.5 = 390$

I hope this helped!

Answer:

y = (25/4)(x + 5)^2

Step-by-step explanation:

1.  Interchange x and y, obtaining:  x = -5 + (2/5)√y

2.  Solve this result for y:  x + 5 = (2/5)√y

    Squaring both sides, we get (x + 5)^2 = (4/25)y

     Multiplying both sides by (25/5) cancels out the (4/25) coefficient:

      y = (25/4)(x + 5)^2       This is the inverse of the given function.

Answer: 2

Step-by-step explanation:

Answer:

36degrees

Step-by-step explanation:

If m<A and m<B are vertical angles, hence m<A = m<B (vertical angles are equal)

Given the following

m<A = (2x+26)°

m<B = (3x+21)°

Equating both expressions

2x + 26 = 3x + 21

2x - 3x = 21 - 26

-x = -5

x = 5

Get the measure of m<B

m<B = (3x+21)°

m<B = 3(5) + 21

m<B = 15+21

m<B = 36degrees

Hence the measure of angle B is 36degrees

Answer:

Answer:

Step-by-step explanation:

(-8x+7y)(-8x+7y)+(2x-2y)(2x-2y)

=64x²-56xy-56xy+49y²+(4x²-4xy-4xy+4y²)

=64x²-112xy+49y²+4x²-8xy+4y²

=68x²-120xy+53y²

Answer:

7pi/theta = radius

Step-by-step explanation:

So we are using the arc length, central angle(in radians), and radius.

We know arc length, which is 7pi.

We don't know theta, which does not matter.

And finally, we don;t know radius, which is what we are looking for.

To find radius, we use:

arc length/theta=radius

Lets plug in our values:

7pi/theta=radius.

So the answer to the khan acadamy question is

7pi/∅

Here are some othr things that may help:

Radian * Radius = arc length

This solves for arc length

Here is another one:

Arc length/radius= radian

This solves for radians

Hope these help! :)

Answer:

2/3 pound of dough is left

Step-by-step explanation:

Amount of dough available = 6 pounds

The amount used in making sandwich rolls = 8/9 of the total amount

= [tex]\frac{8}{9} \times6 = 5\frac{1}{3} pounds[/tex]

Therefore, amount of dough left over [tex]= 6- 5\frac{1}{3} = \frac{2}{3} \\[/tex]

Hence, 2/3 pounds of dough is left

Answer:

Step-by-step explanation:

The common difference is 3.

nth term = -6+(n-1)3

-6+(n-1)3 = 162

(n-1)3 = 168

n-1 = 56

n = 57

162 is the 57th term.

S₅₇ = 57×(a_1+a_{57})/2

= 57×(-6+162)/2

= 57×156/2

= 57×78

= 57×(-6+162)/2

= 4446

Answer:

7.74 minutes

Step-by-step explanation:

Scott's rate = 20 /16 = 1.25

Ashley's rate = 20 / 15 = 1.333

Combined rate = (1.25 + 1.3333) = 2.583333

Hence, time it will take to inflate 20 balloons :

Rate = number of balloons / time taken

2.583333 = 20 / time taken

Time taken = 20 / 2.583333

Time taken = 7.7419

It will take them approximately 7.7 minutes to inflate 20 balloons

Answer:

Pythagoras theorem.

hypotenuse²=base²+height²

(18)²=(11)²+h²

324=121+h

324 - 121 = h²

Answer:

See Explanation

Step-by-step explanation:

Given

[tex]0 \le a \le 1[/tex]

[tex]8*a =b[/tex]

Required

Determine the true statement about b

The question is incomplete as options are not given. However, a general explanation is as follows:

Rewrite [tex]8*a =b[/tex]

[tex]b = 8 * a[/tex]

When a = 0

[tex]b = 8 * 0 = 0[/tex]

When a = 1

[tex]b = 8 * 1 = 8[/tex]

This means that:

For [tex]0 \le a \le 1[/tex]

Then [tex]0 \le b \le 8[/tex]

This means that: b is a number between 0 and 8

Answer:

209.43951 round to the nearest tenth is 209.44

Step-by-step explanation:

A cone with a base radius of 5 units and a height of 8 units has a volume of 209.44 cubed units.

If a cone has a flat bottom, meaning the height and radius meet at right angles, then this formula can be used to find of volume ('V') of that cone (also know as a right circular cone):

V = 1/3(PI*r squared * h )

The volume of a cone can be calculated by taking one-third of the result of the radius squared, multiplied by the height, multiplied by the mathematical constant pi.

Here is a step-by-step case that illustrates how to find to volume of a cone with a radius of 2 feet and a height of 3 feet. Note that in order to save space (and because pi cannot be determine precisely) a limited number of decimal places are used, the symbol ~ denotes that this answer is an approximation.

V = 1/3(pi * r^2 * h)

= 1/3(pi * 2^2 * 3)

= 1/3(pi * 12)

= 1/3(37.7)

~ 12.6 cubic feet
