"The sum of a number and 7"
Sum implies addition.
We would write this part as <em>n + 7</em>.
Then we would write the "9 times" part in like this:
<em>9 </em><em>·</em><em> </em><em>(n + 7)</em><em>
</em>We can't write just 9 · n + 7 without the parentheses, because then we would be multiplying just 9 and n instead of 9 and the sum of n and 7. (order of operations says we must do multiplication first)
Okay, the equation would be: What is 35% of $117
Proportion:
We multiply:
117 x 35 = 4095
Now we divide:
4095 / 100 = 40.95
Then we add:
40.95 + 117 = $157.95
and that's your answer!
I hope this helps! :)
So start:44 3/8 end: 45 1/4
so 44 3/8+x=45 1/4
subtract 44 3/8 from both sides
x=grow=45 1/4-44 3/8
so convert to fractions
45=180/4
45 1/4=181/4
44=352/8
44 3/8=355/8
181/4=362/8
x=362/8-355/8=7/8 inch he grew
Answer:
Step-by-step explanation:
For two objects with a finite constant mass, Fg is inversely proportional to the square of the distance between them. As r gets smaller the gravitational force increases. When the two objects are touching Fg is highest. But the mass of an object is focussed at its centre, the centre of mass. When the objects are touching their centres of mass are still separated. The graph has a vertical asymptote at r=0, implying an infinite gravitational force.
