Hey!
We can round 75,364 to 75,000 and 472,756 to 473,000
75,000 + 473,000 = 548,000
So, the answer is B. 548,000 =)
Answer:
The answer is 36
Step-by-step explanation:
Let the number be <em>x</em>
x/40 is her mark
she got 90% mark correct
x/40 x 100 = 90
by cancellation we get 9 x 4 = 36

Answer:
See below.
Step-by-step explanation:
This is how you prove it.
<B and <F are given as congruent.
This is 1 pair of congruent angles for triangles ABC and GFE.
<DEC and <DCE are given as congruent.
Using vertical angles and substitution of transitivity of congruence of angles, show that angles ACB and GEF are congruent.
This is 1 pair of congruent angles for triangles ABC and GFE.
Now you need another side to do either AAS or ASA.
Look at triangle DCE. Using the fact that angles DEC and DCE are congruent, opposite sides are congruent, so segments DC and DE are congruent. You are told segments DF and BD are congruent. Using segment addition postulate and substitution, show that segments CB and EF are congruent.
Now you have 1 pair of included sides congruent ABC and GFE.
Now using ASA, you prove triangles ABC and GFE congruent.
No, this rel. is not proportional because of the addition involved ("plus 1 lb for each guest").
A proportional rel. features mult. only.
Any multiple of (-2x+3y=18) would constitute an "other equation" forming a system with an infiinite number of solutions. The reason for that is that the two equations would be "dependent."
On the other hand, looking at the system
<span>-2x+ 3y= 18
</span><span>-2x+ 3y= 19
we see that there is no solution. Why? Because -2x + 3y cannot equal 18 and 19 at the same time. You'd have two non-intersecting, parallel lines.
