Laura drove 255 miles in 5 hours.at the same rate, how many miles would she drive in 8 hours

Answer: The answer is 6x–9, please mark me as brainliest and have a wonderful weekend. :D

Step-by-step explanation:

It is wrong. Because Verania has a comparative advantage in washing dishes, she should wash dishes, and Josimar should vacuum.

Having an absolute advantage in both things does not mean that Verania has a Comparative advantage in both as well.

They should find out which activity they both have a comparative advantage in and focus on that. The activity that costs the least opportunity cost is the one they have a comparative advantage.

Verania

Opportunity cost of vacuuming = 2 / 1 = 2 hours of washing dishes

Opportunity cost of washing = 1/2 = 0.5 hours of vacuuming

Josimar

The opportunity cost of vacuuming = 3/2 = 1.5 hours of washing dishes

Opportunity cost of washing = 2/3 = 0.66 hours of vacuuming

Verania has a comparative advantage in washing dishes while Josimar has a comparative advantage in vacuuming.

Answer:

x ≈ 14.7

Step-by-step explanation:

use pythagorean therorem

a^2 + b^2 = c^2

c is hypotenuse and we know the hypotenuse is 21

a^2 + b^2 = c^2

x^2 + 15^2 = 21^2

x^2 + 225 = 441

x^2 = 216

x = √216

x ≈ 14.7

Answer: [tex]\sqrt{170}[/tex]

Step-by-step explanation:

Distance formula: a^2+b^2=c^2 where c is the distance between two points

(-6-5)^2 + (4-(-3))^2=c^2

(-(6+5))^2 + (4+3)^2=c^2

(-11)^2 + 7^2=c^2

121 + 49=c^2

c^2=170

c=[tex]\sqrt{170}[/tex]   ==> distance between A and B

Step-by-step explanation:

Equation of the line

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

The equation of the line in slope-intercept form is:

y = mx + b

Being m the slope and b the y-intercept.

Where m is the slope and (h,k) is a point through which the line passes.

We are given the y-intercept as b=3 m=6.

Thus, the equation of the line is:

y = 6x + 3

Step-by-step explanation:

Here, given the diagonals of the Rhombus, we want to get the length of one side of the Rhombus

We proceed to use the formula below;

d1 = √(4a^2-d2^2

Where d1 represents the length of one diagonal

a is the side of the Rhombus

d2 is the length of the second diagonal

Thus, mathematically;

d2^2 = 4a^2 - d1^2

4a^2 = d2^2 + d1^2

4a^2 = 18^2 + 24^2

4a^2 = 900

a^2 = 900/4

a^2 = 225

a = √225

a = 15

Answer:62 degrees

Step-by-step explanation:  BAC and DAF  are equivalent

The polynomial function has zeroes as given by x=0

In general, given zeroes of a polynomial function, a, b, c, and d, we can write the function as the multiplication of the factors

(x-a), (x-b), (x- c), and (x-d) then the degrees are 4

simply:

f(x)=(x-a) (x-b) (x- c) (x-d)

In this case, we can show that each of a, b, c, and d are zeroes of the function:

f(a)=(a-a) (a-b) (a-c) (a-d)

     = (0) (a-b) (a-c) (a-d)

     =0

f(b)=(b-a) (b-b) (b-c) (b-d)

      =(b-a) (0) (b-c) (b-d)  

      =0

f(c)=(c-a) (c-b) (c-c) (c-d)

     =(c-a) (c-b) (0) (c-d)

     =0

f(d)=(d-a) (d-b) (d-c) (d-d)

     =(d-a) (d-b) (d-c) (0)

     =0

since the value of the function at x=a, x=b, c, and d are equal to 0, then the function

f(x)=(x-a) (x-b) (x- c) (x-d) has zeroes at a, b, c and d

with the generalized form, we can substitute for the given zeroes,

x=-5, x=-2,0and 5 where a=-5, b=-2, c=0 and x=5

f(x)=(x-(-5)) (x-(-2)) (x-0) (x-5)

simplifying gives:

f(x)=(x+5) (x+2) x(x-5)

from here, we can put it in standard polynomial form by foiling the right side:

f(x)=x^3+2x^2-25x-50

To double-check the answer, just plug in the given zeroes, and ensure the value of the function at those points is equal to 0.

f (-5) =x^3+2x^2-25x-50

       =(-5)^3+2(-5)^2-2(-5)-50

f (-5) =0

f (-2) =(-2)^3+2(-2)^2-2(-2)-50

f (-2) =0

f (0) =0

f (5) =(5)^3+2(5)^2-2(5)-50

    =0

Hence, the function has zeroes as given by x=0.

Answer:

b = 12

Step-by-step explanation:

subtract eight from both sides to leave the b variable on the left

b/2 = 14 - 8

b/2 = 6

multiply by 2 on both sides to leave b by itself

b = 6 * 2

b = 12

Answer:

12

Step-by-step explanation:

8 + b/2 = 14

b/2 = 14 -8

      = 6

b = 6 x 2

  = 12

Therefore b is 12. Hope this helps you and pls mark me as brainliest <3

Step-by-step explanation:

1/5 * 35 = 7

Answer:

(- 5, - 3 )

Step-by-step explanation:

Given the 2 equations

- 3x + 10y = - 15 → (1)

5x - 7y = - 4 → (2)

Multiplying (1) by 5 and (2) by 3 and adding the result, eliminates the x- term.

- 15x + 50y = - 75 → (3)

15x - 21y = - 12 → (4)

Add (3) and (4) term by term to eliminate x, that is

29y = - 87 ( divide both sides by 29 )

y = - 3

Substitute y = - 3 into either of the 2 equations and solve for x

Substituting into (1)

- 3x + 10(- 3) = - 15

- 3x - 30 = - 15 ( add 30 to both sides )

- 3x = 15 ( divide both sides by - 3 )

x = - 5

solution is (- 5, - 3 )

(6+1) / 2 =

7/2

3 1/2 min is equivalent to 7/2

Applying the velocity and isolating the distance we have:

x= v*t

x = 2700 ft/min * 7/2 min

x = 9450 ft
