Hi there!
nickels:19
We know that there is only nickels and dimes in his coin collection..
<u><em>1.Multiply two terms:</em></u>
<u><em /></u>
<u><em>·</em></u>
<u><em /></u>
<u><em>Then there would be 20 nickels but 1+1=2 not 2.05.</em></u>
<u><em>2.Multiply the terms:</em></u>
<u><em /></u>
<u><em>·</em></u>
<u><em /></u>
<u><em /></u>
<u><em>·</em></u>
<u><em /></u>
<u><em>3.Combine the two terms:</em></u>
<u><em /></u>
<u><em /></u>
Therefore, there would be 19 nickels...

Answer:
<em><u>17: 480</u></em>
(We first arrange all of the candidates except b in a line. This can be done in 5! ways. We now add b to the line. Since we now want to count the arrangements where b is positioned next to a, there are two possibilities for the position of b. (Either left of a or right of a).
There are thus 2⋅5! ways of arranging the candidates so that a and b are next to each other, and hence 6!−2⋅5!=4⋅5!=480 ways of arranging the candidates so that a and b are not next to each other)
<u><em>18</em><em>:</em></u><em><u> </u></em>i don't know sorry
Answer:
Solution given:
<6+24=180[co- interior angle]
<6=180-24=156°
<6=156°
8 square units
Divide figure into one square, and two triangles
Area of square:
2 x 2 = 4 square units
Area of ONE triangle:
1/2 x 2 x 2 = 2 square units
The triangles we have are both sizes, so multiply this by 2:
2 square units x 2 = 4 square units
ADD THE AREA OF SQUARE AND TRIANGLES:
4 square units + 4 square units = 8 square units
Have a nice day
Knowing how to write two-column geometry proofs provides a solid basis for working with theorems. Practicing these strategies will help you write geometry proofs easily in no time:
Make a game plan. Try to figure out how to get from the givens to the prove conclusion with a plain English, commonsense argument before you worry about how to write the formal, two-column proof.
Look up how to do geometry proofs and the first thing that should pop up if your on google should be a site called dummies.com
