Answer: 5 + 0.5m

Step-by-step explanation:

Let the number of miles be represented by m.

Therefore, since there's a $5 flat rate and an additional $0.50 per mile, this can be formed into a equation as:

= 5 + 0.5m

For example if the number of miles taken is 100miles, the amount charged will be:

= 5 + 0.5m

= 5 + 0.5(100)

= 5 + 50

= $55

Answer:

1849

Step-by-step explanation:

To evaluate an algebraic expression means to find the value of the expression when the variable is replaced by a given number. To evaluate an expression, we substitute the given number for the variable in the expression and then simplify the expression using the order of operations.

Answer:

Square; x=2; y=1

Step-by-step explanation:

Being that the following quaderlateral has equal sides and angles equal to 90 degrees each, it would be classified as a square.

Now, knowing that they have all equal sides, you could say that

1). 5x-4=3x

as well as

2).2y+4=5y+1

Now, solve for each of the variables:

1). 5x-4=3x

    (Minus 3x from both sides and add 4 to both sides)

     2x=4

     (Divide by 2)

     x=2

2). 2y+4=5y+1

    (Minus 5y from both sides and minus 4 to both sides)

   -3y=-3

   (Divide by -3)

      y=1

Answer:

x = - 3 ± 2[tex]\sqrt{3}[/tex]

Step-by-step explanation:

Given

2x² + 12x = 6 ( divide through by 2 )

x² + 6x = 3

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(3)x + 9 = 3 + 9

(x + 3)² = 12 ( take the square root of both sides )

x + 3 = ± [tex]\sqrt{12}[/tex] = ± 2[tex]\sqrt{3}[/tex] ( subtract 3 from both sides )

x = - 3 ± 2[tex]\sqrt{3}[/tex] ← exact solutions

Answer:

The maximum height of the rocket is about 391.1 feet.

Step-by-step explanation:

The height of the rocket y in feet x seconds after launch is modeled by the equation:

[tex]y=-16x^2+125x+147[/tex]

We want to find the maximum height reached by the rocket.

Since this is a quadratic equation, the maximum height occurs at the vertex. The vertex of a quadratic is given by:

[tex]\displaystyle \left(-\frac{b}{2a}, f\left(-\frac{b}{2a}\right)\right)[/tex]

In this case, a = -16, b = 125, and c = 147.

Thus, the x-coordinate of our vertex is:

[tex]\displaystyle x=-\frac{125}{2(-16)}=\frac{125}{32}[/tex]

To find the maximum height, we will substitute this value back in. So:

[tex]\displaystyle y_{\text{max}}=-16\left(\frac{125}{35}\right)^2+125\left(\frac{125}{32}\right)+147\approx391.1\text{ feet}[/tex]

The maximum height of the rocket is about 391.1 feet.

Answer:

You subtract 6,000 by 700= 5,300 Then you subtract 550 by what you got which was 5,300 so the way you do it is now you subtract even more then 550 so 550 by 5,300=4,750 which you basically the answer is 20%

Answer:

(2/3, 13/3)    (Exactly one solution)

Step-by-step explanation:

Write these equations in a column:

 x+y=5

2x-y=-3

Note that we can eliminate y immediately by adding these two equations together. We get:

3x = 2, so that x = 2/3.

Substituting 2/3 for x in the first equation, we get:

2/3 + y = 5.  Clear out fractions by multiplying all three terms by 3:

2 + 3y = 15, or 3y = 13.  Then y = 13/3, and the solution is

(2/3, 13/3)      There is exactly one solution.

We have the formula for pyramid volume V = (B.h)/3 => B = 3V / h

=> B = (216 . 3)/8 = 81 m2

the base area of a square pyramid : 81 m2

Step-by-step explanation:

Answer:

81cm2

Step-by-step explanation:

Volume = 1/3Base area * height

216 =1/3x * 8

Answer:

Least to greatest: 2, 3, 1

Step-by-step explanation:

Square root of 8 over 2 is about 1.41 which makes it the least value

2 is obviously equal to 2 which puts it in the middle

Square root of 7 is about 2.64 which makes it the greatest value

Answer:

x = 5

y = 6

Step-by-step explanation:

-3x + 2y = -3

-x - y = -11  (Multiply everything by 2)

-3x + 2y = -3

-2x - 2y = -22

-5x = -25

x = 5

-x - y = -11

-5 - y = -11

-y = -11 + 5

-y = -6

y = 6

The option which is true is (c) The product is less than 1/4.

Fractions are type of numbers which are written in the form p/q, which implies that p parts in a whole of q.

Here p, called the numerator and q, called the denominator, are real numbers.

Given fraction is 1/4.

When 1/4 is multiplied by 1/2,

1/4 × 1/2 = 1/8 which is less than 1.

If 1/4 is multiplied by 3/4,

1/4 × 3/4 = 3/16, which is less than 8.

The least number that 1/4 is multiplied to gives the number 1/4 itself when multiplied by 1.

So, any number less than 1 when multiplied to 1/4 gives the number less than 1/4.

Hence the correct option is (c).
