What is the density of a material, if 132 grams of the material occupies 3 cubic centimeters?

1 answer:

5 0

You need to divide here, so 132/3 = 44, so that means it's D, 44 g/cm3. Hope this helped! Brainliest is always appreciated.

Answer:

Step-by-step explanation:

x + y(3 − x)

Let x = -5 and y = 3

-5 +3(3 - -5)

Subtracting a negative is like adding

-5 +3(3+5)

Parentheses first

-5 +3(8)

Angle T has a measure between 0° and 360° and is coterminal with a –710° angle. What is the measure of angle T?

disa [49]

To find the coterminal angle to the given angle , we need to add or subtract the multiples of 360 degree . Since here we have to find the coterminal of -710 in 0 to 360, it means we have to find a positive coterminal angle . And to find the positive coterminal angle, if we add just 360 degree, we will get -710+360 = -350, but we need a positive coterminal angle, so we add again 360 , that is -350+360 =10.

So the coterminal of -710 in 0 to 360 is 10 degree .

Which matrix represents the system of equations shown below? 3x-5y=12 4x-2y=15

tatuchka [14]

Answer:

$\left[\begin{array}{ccc}3&-5 &|12\\4&-2 &|15\\\end{array}\right]$

Step-by-step explanation:

When making a matrix of two equations with the variables x and y, the result will be a matrix with three columns:

a column for the values of x in each equation
a column for the values of y in each equation
a column for the independent values of each equation

since our system of equations is:

$3x-5y=12\\ 4x-2y=15$

we can see that the value for x in the first equation is 3 and in the second equation is 4, thus the first column will have the numbers 3 and 4:

$\left[\begin{array}{ccc}3&&\\4&&\\\end{array}\right]$

Now for the values of y we hvae -5 in the first equation and -2 in the second equation, we update the matrix with another column with the values of -5 and -2:

$\left[\begin{array}{ccc}3&-5&\\4&-2&\\\end{array}\right]$

Finally, the last column is the independent values of each equation (or the results) in the first equation that number is 12 and in the second equation is 15, thus the matrix is:

$\left[\begin{array}{ccc}3&-5&12\\4&-2&15\\\end{array}\right]$

usually there is a line separating the columns for the values of x and y, and the independent values:

$\left[\begin{array}{ccc}3&-5 &|12\\4&-2 &|15\\\end{array}\right]$

this is the matrix of the system of equations
