Answer:

a) The value of $n$ is 81.30.

b) The value of $n$ is 81.

Step-by-step explanation:

a) The value of $n$ is the ratio of the mass of the Earth to the mass of the Moon. That is:

$n = \frac{5.972\times 10^{24}\,kg}{7.346\times 10^{22}\,kg}$

$n = 81.30$

The value of $n$ is 81.30.

b) If $n$ is a integer, then the result must have only two significant figures. Given the result, we must approximate to the closest integer. That is:

$n = 81$

The value of $n$ is 81.

Find a counterexample to disprove each statement, or support with four examples. Every quadrilateral has at least two congruent

vaieri [72.5K]

Answer: If every quadrilateral has at least two congruent sides, then an obtuse angle is an quadrilateral.

Step-by-step explanation:

A counterexample is basically the opposite of a conditional statement. So the Hypothesis is true but the conclusion is false. An obtuse triangle has different size sides and congruent sides means same size sides. Hope this helps!!!! Let me know if you need further explanation.

Factor completely: 3a^3b^2c+9ab^2c^3

sleet_krkn [62]

Step-by-step explanation:

$= 3 {a}^{3} {b}^{2} c + 9a {b}^{2} {c}^{3}$

$= (3a {b}^{2} c)( {a}^{2} ) +( 3a {b}^{2} c)(3 {c}^{2} )$

$= 3a {b}^{2} c( {a}^{2} +3 {c}^{2} )$
