Answer:

x= $878.85

Step-by-step explanation:

1349.99=1350

1350=100% you cross multiply and then divide by 100 you get x = 540

x =40%

504 is how much can be off the original price, 1350-504=810

You would pay 810 dollars if the coupon was 40% off. Now we gotta find how much is the tax rate.

810=100% do the cross multiply and then divide by a 100, you get x=68.85

x =8.5

Then you have to add your tax rate to the price that you are paying, 810+68.85=$878.85.

Hope this helps you!

find the minimum value of p=10x+26y the constraints are x+y less than or equal to 6, 5x+y greater than or equal to 10, x+5y grea

Answer:

Minimum value of $p=10x+26y$ is 80 at (1.5,2.5)

Step-by-step explanation:

We are given

The objective function is, Minimize $p=10x+26y$

With the constraints as,

$x+y\leq 6\\5x+y\geq 10\\x+5y\geq 14$

So, upon plotting the constraints, we see that,

The boundary points of the solution region are,

(1,5), (1.5,2.5) and (4,2).

So, the minimum values at these points are,

Points $p=10x+26y$

(1,5) $p=10x\times 1+26\times 5$ i.e. p = 140

(1.5,2.5) $p=10\times 1.5+26\times 2.5$ i.e. p= 80

(4,2) $p=10\times 4+26\times 2$ i.e. p = 92

Thus, the minimum value of $p=10x+26y$ is 80 at (1.5,2.5).

Answer:

Step-by-step explanation:

Calculate the distance d using the distance formula

d = $\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }$

with (x₁, y₁ ) = (- 4, - 6) and (x₂, y₂ ) = (- 9, 6)

d = $\sqrt{(-9+4)^2+(6+6)^2}$

= $\sqrt{(-5)^2+12^2}$

= $\sqrt{25+144}$

= $\sqrt{169}$

= 13

The population of town A increases from 1,346 to 1,500. In the same period, the population of town B increases from 1,546 to 1,8

Yuki888 [10]

a. you would do 1346/1500 to get 0.8973333333333. i you want to check that you can do 1346/0.8973333333333 and you would get 1500. I'm just going to round 0.8973333333333 down to 0.897. So for town B you would also do 1546/1800 which brings you to 0.858889 you can again do 1546/0.858889 but i found that 0.8588888888 gives you the most accurate answer. so rounding that down to 0.859

b. you can see that 0.897 is a larger percent that 0.859 so town a had a larger increase than b

How determine if it is proportional

siniylev [52]

If you cross multiply and the answers are the same.
2/5=4/10 because 5*4=20, and 10*2=20
