Answer:

The ordered pair that satisfies this problem is (1, -6); x = 1 when y = -6.

Step-by-step explanation:

Please, rewrite your question as follows:

"Suppose that y varies directly with x and y = 12 when x = -2. What is x when

y = -6?" The " = " sign must be included.

The pertinent proportional relationship is y = kx, where k is the constant of proportionality.

We must find k here. Let y = 12 and x = -2. Then 12 = k(-2), or k = -6.

Then the relationship is y = -6x.

Now let y = -6 and find x: -6 = -6x, or x = 1.

The ordered pair that satisfies this problem is (1, -6)

What can you say about the relationship between M and P? Which letter is the correct answer?

Dimas [21]

Answer:

Choice C is correct

Step-by-step explanation:

The first step is to re-write the equations in exponential form.

The first equation can be written as;

$\frac{M}{N}=10^{4}$ since the base is 10 and 4 the exponent.

The second equation can be written as;

$\frac{P}{N}=10^{5}$

The second step is to make N the subject of the formula in both equations.

Solving for N from this equation $\frac{M}{N}=10^{4}$ , yields;

$N=\frac{M}{10^{4}}$

Solving for N from the second equation $\frac{P}{N}=10^{5}$ , yields;

$N=\frac{P}{10^{5}}$

Therefore;

$\frac{M}{10^{4}}=\frac{P}{10^{5} }\\\\P=10M$

A kitchen sink has a volume of 1800 cubic inches.What is the volume of a similar sink that is larger by a scale factor of 2

bonufazy [111]

Answer:

14400 cubic inches.

Step-by-step explanation:

Let l, b and h are length, breadth and height of a cuboid respectively, then

$V=l\times b\times h$

If another cuboid is larger by a scale factor of k, then kl, kb and kh are length, breadth and height of new cuboid respectively.

$V_1=kl\times kb\times kh$

$V_1=k^3(l\times b\times h)$

$V_1=k^3V$ ...(i)

It is given that a kitchen sink has a volume of 1800 cubic inches and a similar sink is larger by a scale factor of 2.

Substitute k=2 and V=1800 in equation (i).

$V_1=2^3(1800)$

$V_1=14400$

Therefore, the volume of required sink is 14400 cubic inches.
