Answer: 600/20 = 30 miles/gallon 30mi/gal (75 gallons) = 2250 miles

Step-by-step explanation:

Answer:

a = 3

b = 2

Step-by-step explanation:

(x - 3)² - 9 + 7 = 0

(x - 3)² - 2 = 0

x - 3 = ± √2

x = 3 ± √2

And they want the answer in the formula so a = 2 and b = 2

Answer:

31/12

First,

Figure out what the whole number represents.

2 = 24

Next,

Add 24 + 7 (the numerator)

24 + 7 = 31

Finally,

31 is the new numerator for the improper fraction.

Answer:

P(4.7≤x≤5.3)≈0.6827≈68.27%

Step-by-step explanation:

Notice that 4.7 is 1 standard deviation below the mean (μ) and 5.3 is 1 standard deviation above the mean. Thus, by the Empirical Rule, ±1σ represents about 68.27% of the data in a normal distribution, meaning that P(4.7≤x≤5.3)≈0.6827

Step-by-step explanation:

Because $75-$50=$25

Usando proporciones, hay que con 200 pesos mx se pueden comprar 0.0645 yenes.

Una proporción es una fracción de la cantidad total, y puede ser encontrada por intermedio de una regla de tres.

En este problema, hay que un yene cuesta $0.17, enquanto $1 = 3100 pesos. Por eso, cada yene es equivalente a 3100 pesos.

Por eso, la regla de tres es:

1 yene - 3100 pesos

x yenes - 200 pesos

Aplicando multiplicación cruzada:

[tex]3100x = 200[/tex]

[tex]x = \frac{200}{3100}[/tex]

[tex]x = 0.0645[/tex]

Con 200 pesos mx se pueden comprar 0.0645 yenes.

Yes, you have made a profit.

Step-by-step explanation:

Basically, profit just means that you end up having more money than you started with.

Since you started with 10 and got a 20 in exchange for it, you now have 10 dollars more than you previously did, meaning you made a profit.

Answer:

3[tex]\sqrt{10}[/tex] = x

Step-by-step explanation:

This is a right triangle and in right triangles the sum of square length of two legs is equal to square length of hypotenuse.

Now let x represent the third side:

9^2 + 10^2 = x^2

81 + 100 = x^2

181 = x^2 find the root for both sides

3[tex]\sqrt{10}[/tex] = x

Answer:

  47.25 ft³

Step-by-step explanation:

The volume of the prism is given by the formula ...

  V = Bh . . . . . . . B is the area of the base, h is the height.

The height of the prism is given as 6 ft. The area of the base is the area of the triangular entrance. The formula for that area is ...

  A = 1/2bh . . . . . . b is the base, h is the height

Using the given values for the entrance base and height, we get ...

  A = 1/2(4.5 ft)(3.5 ft) = 7.875 ft²

Then the volume of the tent is ...

  V = (7.875 ft²)(6 ft) = 47.25 ft³

The tent volume is 47.25 cubic feet.

Step-by-step explanation:

remember that x^-n means 1/(x^n).

x^a × x^b = x^(a+b)

x^a / x^b = x^(a-b)

(x^a)^b = x^(a×b)

(x×y)^n = x^n × y^n

so,

a^2 / a^-2 = a^(2 - -2) = a^4

and

b^-3 / b^2 = b^(-3 - 2) = b^-5 = 1/(b^5)

that means we have then :

(a^4 × b^-5)^2 = (a^4)^2 × (b^-5)^2 = a^8 × b^-10 =

= a^8 / b^10 = a⁸/b¹⁰

Step-by-step explanation:

all regular polygons have (n-2)*180 this formula can use here. n= no of sides

Answer:

M = (n-2)*180 degrees for polygons with n sides.

Step-by-step explanation:

As already noted, there is no description of the polygon in question.  However, the formula for the sum of the measure of the interior angles of a regular polygon is M = (n-2)•180 where n is the number of sides.  A triangle has 3 sides, so M = (3-2)*180 = 180 degrees.

A hexagon has 6 sides, so M = (6-2)*180 = 720.

Step-by-step explanation:

5x + 2 + 3x = 8x + 2

3 + 17x + 8 = 17x + 11

19 + 6x + 2x = 8x + 19

14x + 7 + 4 = 14x + 11

9x - 3 - 7x + 4 = 2x + 1

12x + 3x - 6 - 7f = 15x - 7f - 6

14x + 7 - 3x = 11x + 7

13z + 6u + 8x + 19 - u = 13z + 5u + 8x + 19

3z + 6 + 4z + 9 + 8u = 7z + 8u + 15

2x + 8z + 13u + 6z + 4u = 2x + 14z + 17u

14y + 13x + 12y + 19x + 4 = 26y + 32x + 4

5x + 18 - 13y + 12x + 8y = 17x - 5y + 18

21v + 8 - 12v - 7 + 3t - t = 9v + 2t + 1

3t + v - t + 7v = 2t + 8v

-1 + 18x -3y + x + 9y = 19x + 6y - 1

Step-by-step explanation:

Simply divide for example 64 divided by 4.

The solution of the system of equation is (-7, -2).

The system of the equations;

[tex]\rm y^2 + x^2 = 53 \\\\y -x = 5[/tex]

From equation 1

[tex]\rm y -x=5\\\\y = 5+x[/tex]

Substitute the value of y in equation 1

[tex]\rm y^2+x^2=53\\\\(5+x)^2+x^2=53\\\\25+x^2+10x+x^2=53\\\\2x^2+10x+25-53=0\\\\2 x^2 + 10x - 28 = 0 \\\\Divide \ by \ 2 \ both \ side \ the \ equation\\\\x^2 + 5x - 14 = 0\\\\x^2-7x+2x-14=0\\\\x(x-7) + 2(x-7) =0\\\\(x-7) \ (x+2)=0\\\\x-7=0 \ \ x = 7\\\\x +2 =0 \ \ x=-2[/tex]

The value of x= 2 is rejected because x = 2 not satisfy the equation.

Substitute 2 for the value of x in equation II

y − x = 5

y – 2 = 5

y = 5 +2

y = 7 (x =2, y =7) … Not included in the options

If x = -7

Substitute the value of x = -7 in the equation

[tex]\rm y -x=5\\\\y - (-7)=5\\\\y +7= 5\\\\y = 5-7\\\\y = -2[/tex]

Hence, the solution of the system of equation is (-7, -2).
