In one U.S. city, the taxi cost is $5 plus $0.90 per mile. If you are traveling from the airport, there is an additional charge of $5.00 for tolls. How far can you travel from the airport by taxi for $59.50?

Answer:

The solution is:

Step-by-step explanation:

We have the following equation

[tex]-4(2x+3)=2x+6-(8x+2)[/tex]

To solve the equation apply the distributive property

[tex]-4(2x+3)=2x+6-(8x+2)[/tex]

[tex]-4*2x+3(-4)=2x+6-(1)*8x+2*(-1)[/tex]

Now simplify the expression

[tex]-8x-12=2x+6-8x-2[/tex]

[tex]-8x-12=-6x+4[/tex]

Add 6x +12 on both sides of the equation

[tex]-8x-12+6x+12=-6x+4+6x+12[/tex]

[tex]-2x=4+12[/tex]

[tex]-2x=16[/tex]

Divide both sides of the equality between -2

[tex]\frac{-2}{2}x=\frac{16}{-2}[/tex]

Answer:

[tex]330,\frac{5\pi }{3},\frac{7\pi }{6}, \frac{2\pi }{3} ,\frac{\pi }{2}[/tex]

Step-by-step explanation:

We have to find the alternate angles regarding π

So,

[tex]\frac{\pi }{2} = 90 \\330\\\frac{5\pi }{3} = 300\\\frac{7\pi }{6} = 210\\\frac{2\pi }{3} = 120[/tex]

As we have all the angles in number form, we can sort them in descending order to get the answer

330, 300, 210, 120, 90

Writing using pi form

[tex]330,\frac{5\pi }{3},\frac{7\pi }{6}, \frac{2\pi }{3} ,\frac{\pi }{2}[/tex]

Hence, Option D is correct ..

Answer:

D) 330, [tex]\frac{5\pi }{3}[/tex], [tex]\frac{7\pi }{6}[/tex], [tex]\frac{2\pi }{3}[/tex], [tex]\frac{\pi }{2}[/tex]

Step-by-step explanation:

To find the order from greatest to least, we need to convert all [tex]\pi[/tex] terms to degrees.

We know that π = 180°

[tex]\frac{\pi }{2} = \frac{180}{2} = 90[/tex]

[tex]\frac{5\pi }{3} = \frac{5*180}{3} = \frac{900}{3} = 300[/tex]

[tex]\frac{7\pi }{6} = \frac{7*180}{6} = \frac{1260}{6} = 210[/tex]

[tex]\frac{2\pi }{3} = \frac{2*180}{3} = \frac{360}{3} = 120[/tex]

Now we have converted all in degrees. Let's arrange them from greatest to least.

330, 300, 210, 120, 90

Let's write them using [tex]\pi[/tex] term.

330, [tex]\frac{5\pi }{3}[/tex], [tex]\frac{7\pi }{6}[/tex], [tex]\frac{2\pi }{3}[/tex], [tex]\frac{\pi }{2}[/tex]

Therefore, the answer is D) 330, [tex]\frac{5\pi }{3}[/tex], [tex]\frac{7\pi }{6}[/tex], [tex]\frac{2\pi }{3}[/tex], [tex]\frac{\pi }{2}[/tex]

Answer:

Felicia is 7 years old

Explanation:

The variable, d, can represent Danny's age.

The variable, f, can represent Felicia's age.

Basically, using the information provided, you can make two equations.

1.) d - f = 21

2.) d + f = 35

This is a system of equations. To solve for this, I'm going to subtract the 2 equations:

    d - f = 21

-   d + f = 35

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

    -2f = -14

       f = 7

If Felicia is 7, and they're total ages added is 35, subtract 7 form 35

35 - 7 = 28

So, Danny would be 28.

To double check your answers;

28 + 7 = 35

28 - 7 = 21

So Felicia is 7 years old. I hope this helps! :)

To factor the cubic polynomial 3y4 - 2y2 - 5, we first find the common factor which in this case is none. The next step is to try grouping, and if that's not possible, we can solve the polynomial using the quadratic formula or synthetic division. However, this polynomial does not seem to be factorable with integer values.

Unfortunately, without additional context, it's not clear what grid the problem refers to, or where the location you're supposed to place the factors is. It's likely this refers to some sort of tool or diagram provided by your teacher or textbook. In general, you would write down the factors in their proper locations in that tool or diagram, according to the rules or guidelines you were given.

Answer:

Answer is =2x^3+3x^2-11x-6

Step-by-step explanation:

First of all multiply first and second bracket.

=x(2x+1) -2(2x+1)

=2x^2+x-4x-2

=2x^2-3x-2

Now multiply 2x^2-3x-2 with (x+3)

=x(2x^2-3x-2) +3(2x^2-3x-2)

=2x^3-3x^2-2x+6x^2-9x-6

=2x^3+3x^2-11x-6

The expansion and simplification of the expression (2x + 1)(x - 2)(x + 3) is 2x^3 + 3x^2 - 11x - 6.

To expand and simplify the expression (2x + 1)(x - 2)(x + 3), we use the distributive property (a(b + c) = ab + ac) to distribute each term of one binomial with each term of the others.

We start by expanding the first two brackets : (2x + 1)(x - 2). This gives 2x^2 - 4x + x - 2 or, 2x^2 - 3x - 2.

Now, we expand the above result with (x + 3): (2x^2 - 3x - 2)(x + 3) yielding 2x^3 - 3x^2 - 2x + 6x^2 - 9x - 6.

When we simplify that, we get : 2x^3 + 3x^2 - 11x - 6. So, the expansion and simplification is : (2x + 1)(x - 2)(x + 3) = 2x^3 + 3x^2 - 11x - 6.

Answer: Option C

[tex]y=5[/tex], [tex]x=10[/tex]

Step-by-step explanation:

If the lines m and n are parallel then the large triangle and the small triangle are similar triangles, because they have equal angles.

By definition for similar triangles it is satisfied that if they have sides of length a, b, c and a ', b' and c 'then:

[tex]\frac{a}{a'}=\frac{b}{b'} =\frac{c}{c'}[/tex]

In this case

[tex]a = 12\\a' = 4\\c = 15\\c' = y[/tex]

So:

[tex]\frac{12}{4}=\frac{15}{y}[/tex]

[tex]3=\frac{15}{y}[/tex]

[tex]y=\frac{15}{3}[/tex]

[tex]y=5[/tex]

Therefore

if [tex]x+y=15[/tex] and [tex]y=5[/tex] then [tex]x =10[/tex]

[tex]x=2- 3\sqrt{2}[/tex] or [tex]x=2+3\sqrt{2}[/tex]

Step-by-step explanation:

We want to solve for x in the equation;

Add 18 to both sides

[tex](x-2)^2=18[/tex]

We solve by the square root method.

[tex]x-2=\pm \sqrt{18}[/tex]

[tex]x-2=\pm 3\sqrt{2}[/tex]

Add 2 to both sides

[tex]x=2\pm 3\sqrt{2}[/tex]

Split the plus or minus sign.

[tex]x=2- 3\sqrt{2}[/tex] or [tex]x=2+3\sqrt{2}[/tex]

Therefore the exact solution is [tex]x=2- 3\sqrt{2}[/tex] or [tex]x=2+3\sqrt{2}[/tex]

Answer:

3.2 miles

Step-by-step explanation:

The "mean" of a set of numbers is the average. To get this, you add up all of the numbers and then divide by however many there are. So, let's lay out the races that Kim ran.

1, 1, 1, 2, 2, 2, 2, 2, 2, 5, 5, 5, 5, 10

These numbers add up to 45 total miles ran. You can add them up individually or make an equation.

x = (3 × 1) + (6 × 2) + (4 × 5) + (1 × 10)

x = 3 + 12 + 20 + 10

x = 15 + 30

x = 45

Now, divide by the total number of races, 3 + 6 + 4 + 1 = 14

So, the mean will be

45 ÷ 14 = 3.21 or about 3.2

Since the triangle is right using the cosine ratio to solve for BC

noting that the exact value of cos45° = [tex]\frac{1}{\sqrt{2} }[/tex], so

cos45° = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{BC}{n}[/tex]

Multiply both sides by n

n × cos45° = BC

n × [tex]\frac{1}{\sqrt{2} }[/tex] = BC

[tex]\frac{n}{\sqrt{2} }[/tex] × [tex]\frac{\sqrt{2} }{\sqrt{2} }[/tex] = BC

Hence BC = [tex]\frac{n\sqrt{2} }{2}[/tex] → D

The right-angle triangle is given with one angle of 45 degrees. The length of segment BC is n√2/2.

A right-angle triangle is a triangle that has a side opposite to the right angle the largest side and is referred to as the hypotenuse.

The angle of a right angle is always 90 degrees.

Since the triangle is right angle

by using the cosine ratio to solve for BC

The value of cos45° = 1/√2 ,

So,

cos45° = BC / AC = BC / n

Multiply both sides by n

n × cos45° = BC

n × 1/√2 = BC

n/√2 × √2 /√2 = BC

Hence, BC = n√2/2

There are 5 stacks of huge waffles that each weigh 45 pounds.

Hence, Total amount of waffles=5×45 pounds

Answer:

The y-intercept indicates that the phone card started with 850 minutes. The slope indicates that 50 minutes were used per day.

Step-by-step explanation:

The graph cuts the y-axis at 850.This indicates that the phone card started with 850 minutes before it was used.

The slope of the graph is -50.This means that in every increase of one in the input variable (number of days), you get a decrease of 50 in the output variable (number of minutes remaining). This indicates every day, 50 minutes were used, hence 50 minutes reduced from the card per day.

The answer is A. The y-intercept indicates that the phone card started with 850 minutes. The slope indicates that 50 minutes were used per day.

This is because she started with 850 and the graph shows a decrease, so this means that she loses 50 per day or that she uses 50 per day.
