Answer:

The 40% marked up price of refrigerator is  $1260.

Step-by-step explanation:

The cost price of the refrigerator  = $900

Now, the mark up should be 40%

Calculating the markup on the cost price , we get

40 % of $900  =  \frac{40}{100}  \times 900 = 360

or, 40 % mark up = $360

Now, the Marked up cost = Cost Price + Marked up Price

                                          = $900 + $360 = $1260

Hence, the 40% marked up price of refrigerator is $1260.

Answer:

x= -3

y= -5

Step-by-step explanation:

10y - 3x = -41

+

-5y + 3x = 16

10y + (-5y) = 5y

-3x + 3x = 0

-41 + 16 = -25

5y + 0 = -25

y = -25/5

y= -5

10y -3× = -41

(10×-5) - 3x = -41

- 3x = - 41 + 50

- 3x = 9

x = -3

Help, I tried it, but I keep getting the wrong answers
Aneli [31]

Answer:

my answer would be that

x = 17.91cm

(i'm not sure about it either but it's worth a try) !!

Step-by-step explanation:

so first off, using the equation given,

" c² = a² + b² — 2ab cos C "

we substitute the values in as,

a = 16

b = 30

then for C is the angle given, which is 30°

so the equation is now,

c² = (16)² + (30)² — 2(16)(30) cos 30°

now, you solve the two squared numbers and the back equation, also known as " 2ab cos C " with your scientific calculator.

so it now equals to,

c² = 256 + 900 — 960(0.87)

c² = 320.8

at last, when you have " c² = 320.8 " ,

remember to square root the answer so you have a smaller value.

so,

c equals to

\sqrt{320.8}

your final answer for the x value will be 17.91

(i hope this helps!)

Which matrix represents the system of equations shown below?
Kazeer [188]

So matrix which show equation 4x+2y=4 is  \left[\begin{array}{ccc}4&2&4\\12&-1&26\end{array}\right] .

Given that we have an equation that is 4x+2y=4

So equation is a statement that the values of two mathematical expressions are equal (indicated by the sign =).

So in order to write this equation in matrix form we have to write it into augmented matrix

So augmented matrix is a matrix whose elements are the coefficients of a set of simultaneous linear equations with the constant terms of the equations entered in an added column.

Therefore the matrix will be:

\left[\begin{array}{ccc}4&2&4\\12&-1&26\end{array}\right]    .
