Answer:

It would cost $ 408.04 to travel 2727 miles

Divide total miles by miles per gallon:

2,727 / 27 = 101 gallons.

Multiply total gallons by price per gallon:

101 x 4.04 = $408.04  Round as needed.

Answer:

The system has of the equation has no solution

Thus,

NO SOLUTION!

Step-by-step explanation:

Given the system of equations

[tex]\begin{bmatrix}y=-6x+2\\ -12x-2y=4\end{bmatrix}[/tex]

Arrange equation variables for elimination

[tex]\begin{bmatrix}y+6x=2\\ -2y-12x=4\end{bmatrix}[/tex]

[tex]\mathrm{Multiply\:}y+6x=2\mathrm{\:by\:}2\:\mathrm{:}\:\quad \:2y+12x=4[/tex]

so

[tex]\begin{bmatrix}2y+12x=4\\ -2y-12x=4\end{bmatrix}[/tex]

adding both equations

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

[tex]+[/tex]

[tex]\underline{2y+12x=4}[/tex]

[tex]0=8[/tex]

so

[tex]\begin{bmatrix}2y+12x=4\\ 0=8\end{bmatrix}[/tex]

0 = 8 is false, therefore the system has of the equation has no solution

Thus,

NO SOLUTION!

Answer:

150 cm^2

Step-by-step explanation:

Keep in mind that the dimensions of the cube are identical in 6 directions.  This means that the surface area of the bottom is 5 cm by 5 cm, yielding the area 25 cm^2.  The top has the same area, so considering top and bottom we get a total surface area of 50 cm^2.

Likewise, the total surface area of the sides together is 50 cm^2.  The total surface area of the front and back together is 50 cm^2.

Thus, the total surface area of the entirre cube is 3(50 cm^2), or 150 cm^2

Answer:

[tex]x^2+12x-220=0[/tex] -- Proved

[tex]x = 10\ \ \ x = -22[/tex]

Step-by-step explanation:

Given

[tex]Volume = 924cm^3[/tex]

[tex]Dimension: 4cm; (x+1)cm; (x+11)cm[/tex]

Required

Show that [tex]x^2+12x-220=0[/tex]

The volume is calculated as:

[tex]4 * (x + 1) * (x + 11) = 924[/tex]

Open the brackets

[tex](4x + 4) * (x + 11) = 924[/tex]

[tex]4x^2 + 44x + 4x + 44 = 924[/tex]

[tex]4x^2 + 48x+ 44 = 924[/tex]

Collect Like Terms

[tex]4x^2 + 48x+ 44 - 924=0[/tex]

[tex]4x^2 + 48x -880=0[/tex]

Divide through by 4

[tex]\frac{4x^2}{4} + \frac{48x}{4} -\frac{880}{4}=0[/tex]

[tex]x^2+12x-220=0[/tex]

Solving further:

Expand the expression

[tex]x^2 + 22x - 10x - 220 = 0[/tex]

Factorize:

[tex]x(x + 22) - 10(x + 22) = 0[/tex]

[tex](x - 10)(x + 22) = 0[/tex]

Split:

[tex]x - 10 = 0;\ \ \ x + 22 = 0[/tex]

[tex]x = 10\ \ \ x = -22[/tex]

Answer:

Mai travels 2.5 meters in 1 second

Priya travels 2.2 meters in 1 second

Step-by-step explanation:

Try finding how many meters they travel in ONE second) Mai and Priya were on scooters.

For Mai

Mai traveled 15 meters in 6 seconds.

Hence,

6 seconds = 15 meters

1 second = x meters

Cross Multiply

6x = 15 meters

x = 15/6

x = 2.5 meters

Hence, Mai travels 2.5 meters in 1 second

For Priya

Priya travels 22 meters in 10 seconds.

Hence,

10 seconds = 22 meters

1 second = x meters

Cross Multiply

10x = 22 meters

x = 22/10

x = 2.2 meters

Hence, Priya travels 2.2 meters in 1 second

Answer:

my question is also this thanks

Answer:

y = -y

Step-by-step explanation

So since we know that the answer of this question turns out to be a positive, and 5 is a negative number, that means y is negative. Heres my reason why:

( write this down on your essay)

Since a negative number and another negative number added becomes a positive, y would be a negative number.

Therefore, It is true that y is a negative number

Answer:

k = ±6

Step-by-step explanation:

guess your question is 4k²–144 = 0??

4k² = 144

k² = 36

k²–36 = 0

(k+6)(k–6) = 0

k+6 = 0 | k–6 = 0

k = –6, k = 6.

Alternatively; k = ±6.

Answer:

u=47

Step-by-step explanation:

...................

The measure of angle U is 74 degrees.

In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.

here, we have,

to determine the measure of angle U:

From the question, we have the following parameters that can be used in our computation:

△PQR ≅ △STU

If m ∠P = 62 degrees and m ∠Q = 45 degrees

The above parameters mean that

P  = S Q = T and R = U

So, we have

U = R = 180 - P - Q -- by the angles in a triangle theorem

So, we have

U = 180 - 61 - 45

   = 74

Evaluate

U = 74

Hence, the value of m ∠U is 74 degrees

Answer:

n = 5 ; n = -1

Step-by-step explanation:

n - 3 = 2

When you transfer (-3) to the other side of the equation, it turns into (+3).

n = 2 + 3

Evaluate.

n = 5

n + 3 = 2

When you transfer (+3) to the other side of the equation, it turns into (-3).

n = 2 - 3

Evaluate.

n = -1

Answer:

[tex]\overrightarrow{AB }=\begin{bmatrix}-4\\3 \end{bmatrix}[/tex]

Step-by-step explanation:

Column Vector

Vectors are matrices having only one column or one row. A vector having only one column is called a column vector, and a vector having only one row is called a row vector.

It's required to find the vector AB as a column vector, and we are given the coordinates of A=(6,4) and B=(2,7).

The vector directed from A to B is found by subtracting its corresponding coordinates:

[tex]\overrightarrow{AB }=<2-6,7-4>[/tex]

[tex]\overrightarrow{AB }=<-4,3>[/tex]

Now we express the vector as a one-column matrix as follows:

[tex]\overrightarrow{AB }=\begin{bmatrix}-4\\3 \end{bmatrix}[/tex]

Step-by-step explanation:

3y+48=90

3y=90-48

3y=42

y=14 degree

12+2x+3x+90=180

5x+102=180

5x=180-102

5x=78

x=15.6 degree

Answer:

-10

Step-by-step explanation:

the equation is in y=mx + b form so the b is the y-intercept so therefore it is -10
