Olly will pay 15.6 because 78 - 15% but you add your 5 percent that’s 20 percent so just do 78 - 20% and you will get 15 dollars and six cents

$62.40

When adding up all the discounts, it is 20%. In order to figure out how much he has to pay, you do 78 times 0.80 (since you’re only paying 80% of the money for the shirt). This gets you 62.4 which is 62.40 in cash.

Consider the curve defined by 2x2+3y2−4xy=36 2 x 2 + 3 y 2 − 4 x y = 36 .
8_murik_8 [283]

Answer:

Step-by-step explanation:

Given a curve defined by the function 2x²+3y²−4xy=36

The total differential of this function with respect to a variable x makes the function an implicit function because it contains two variables.

Differentiating both sides of the equation with respect to x we have:

4x+6ydy/dx-(4xd(y)/dx+{d(4x)/dx(y))} = 0

4x + 6ydy/dx -(4xdy/dx +4y) = 0

4x + 6ydy/dx - 4xdy/dx -4y = 0

Collecting like terms

4x-4y+6ydy/dx - 4xdy/dx = 0

4x-4y+(6y-4x)dy/dx = 0

4x-4y = -(6y-4x)dy/dx

4y-4x = (6y-4x)dy/dx

dy/dx = (4y-4x)/6y-4x

dy/dx = 2(2y-2x)/2(3y-2x)

dy/dx = 2y-2x/3y-2x proved!

Ramen purchase a box of candy for himself on the way back to the dorm he ate 2/3 of the candy while he was putting away grocerie
Aleksandr [31]

Answer:

12 chocolates

Step-by-step explanation:

Represent the original number of chocolates by c.  

Then (1/4)(2/3)c = 2

Solving this for c, we multiply both sides by 4:  (2/3)c = 8

and then multiply both sides by (3/2):  c = (3/2)(8) = 12

Originally the box contained 12 chocolates.

Someone help me solve this it's easy i just don't understand simple math
Lady_Fox [76]

Answer:

The equation — E = mc2 — means "energy equals mass times the speed of light squared." It shows that energy (E) and mass (m) are interchangeable; they are different forms of the same thing. If mass is somehow totally converted into energy, it also shows how much energy would reside inside that mass: quite a lot.
