Damm [24]

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>10<u><em>·</em></u>10=1.00<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>11<u><em>·</em></u>10=1.10<u><em /></u>

<u><em /></u>19<u><em>·</em></u>5=0.95<u><em /></u>

<u><em>3.Combine the two terms:</em></u>

<u><em /></u>1.10+0.95=2.05<u><em /></u>

Therefore, there would be 19 nickels...

PLEASE HELP ASAP WILL GIVE BRAINLIES
Lisa [10]

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)

Find the area for this figure
Westkost [7]
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
