Answer:

$-\frac{5}{3}$

Step-by-step explanation:

Given expression:

(w)(3w + 5) = 0

Expand the parentheses;

3w² + 5w = 0

3w² = -5w

Divide both sides by w;

3w = - 5

w = $-\frac{5}{3}$

Multiply or divide as indicated. Leave your answer with no factors in the denominator. p⁻⁴q⁵r⁶/p⁻³qr⁻²

KIM [24]

Answer: $\frac{q^4r^8}{p}$

Step-by-step explanation:

By the Negative exponent rule, we know that:

$a^{-1}=\frac{1}{a}$

By the Quotient of powers property, we know that:

$\frac{a^m}{a^n}=a^{(m-n)$

And by the Product of powers property, we know that:

$(a^m)(a^n)=a^{(m+n)}$

Applying this properties, we get:

$\frac{p^{-4}q^5r^6}{p^{-3}qr^{-2}}=\frac{p^3q^5r^6r^2}{p^4q}=\frac{q^4r^8}{p}$

How might a psychiatrist describe a paper plate?

spayn [35]

Answer:

A psychiatrist interprets the thing based on its physical appearance and sometimes in a way that is beyond everyone's imagination so in case of paper plate instead of thinking it as a plate used for eating or something, a psychiatrist may only go upon its physical properties that it is made up of paper and end up in describing it as a piece of paper.

So, A psychiatrist might describe a paper plate as a simple piece of paper.

The mean weight of five complete computer stations is 167.2 pounds. The weights of four of the computer stations are 158.4 pound

Lynna [10]

The mean weight of five complete computer stations is 167.2 pounds.

The weights of four of the computer stations are 158.4 pounds, 162.8 pounds, 165 pounds, and 178.2 pounds.

We have to determine the weight of fifth computer station.

Let the weight of fifth computer station be 'x' pounds.

Mean is calculated by sum of all the observations divided by the total number of observations.

So, $\frac{158.4+162.8+165+178.2+x}{5}=167.2$
