Answer:

Part a .............> x = 11

Part b .............> k = 57.2

Part c .............> y = 9.2

Explanation:

The three problems deal with inverse variation between two variables

An inverse variation relation between two variables means that when one of the variables increases, the other will decrease (and vice versa)

Mathematically, an inverse variation relation is represented as follows:

$y = \frac{k}{x}$

where x and y are the two variables and k is the constant of variation

Now, let's check the givens:

Part a:

We are given that y = 3 and k = 33

Substitute in the original relation and solve for x as follows:

$y = \frac{k}{x}\\ \\3 = \frac{33}{x}\\ \\x=\frac{33}{3}=11$

Part b:

We are given that y = 11 and x = 5.2

Substitute in the original relation and solve for k as follows:

$y=\frac{k}{x}\\ \\11=\frac{k}{5.2}\\ \\k=11*5.2=57.2$

Part c:

We are given that x=7.8 and k=72

Substitute in the original relation and solve for y as follows:

$y=\frac{k}{x}=\frac{72}{7.8}=9.2$ to the nearest tenth

Hope this helps :)

Replace ∗ with a monomial so that the expression can be rewritten as a square of a sum or a difference:

Anit [1.1K]

Answer:

x^2

Step-by-step explanation:

The formula we should use here is (a+b)^2=a^2+2ab+b^2

Using this we should first squared 36, getting us 6

Then divide -12x by 6, getting us -2x

Then we divide-2x by -1, getting us 2x

Lastly we divide 2x by 2 to get x

x is our original factors, but to fit in the equation, we need to square it

A right rectangular prism has a length of 9 units, a width of 10 units, and a height of 11 units. What is the number of unit cub

Fynjy0 [20]

Answer:

990 unit³

Step-by-step explanation:

Given that:

Length = 9 units

Width, = 10 units

Height, = 11 units

Volume, V is given by :

V = length * width * height

V = 9 units * 10 units * 11 units

Volume, V = 990 unit³
