Answer:

$\huge \colorbox{blue}{B}$

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>

equation
PEMDAS

<h3>let's solve:</h3>

we are given the formula,Mass and volume

to find density we just need to substitute the value of mass and value and simplify it

$\sf substitute \: the \: value \: of \: mass \: and \: volume :$

$\quad \: \sf \dfrac{7.0 \times {10}^{24} \: kg }{3.5 \times {10}^{12} \: {km}^{3} }$

now we will use $\dfrac{x^m}{x^n}=x^{m-n}$ to simplify division

$\sf simplify \: division : \\ \quad \: \sf 2 \times {10}^{24 - 12} \times \frac{kg}{ {km}^{3} } \\ \quad \tt 2 \times {10}^{12} \frac{kg}{ {km}^{3} }$

hence, our choice is $B$

an item was selling for $72 is reduced to $60 find the precent decrease in price round your answer to the nearest tenth

natima [27]

Remember this, 5 or higher goes up, 4 or lower the number stays the same. soooo.... lets see how i can start this off...
well,... you could....60 divided by 72 equals.... 0.8333333333333
then, starting from the decimal.. you go two spaces to the right... so thats 83.3333333333
so, since 3 is lower than 4, it would be the same.. and take off the extra three after the decimal. and we're basically... rounding off right??
so your answer should be 80%
Hope i helped!!! :D

If you get a 70% on a 20 question test, how many questions did you get right? how many did you get wrong?

70 divided by 5 is 14 14 would be right and 6 would be wrong
