tens place can be filled with 2,3,5,7,8,9

number of ways=6

Hundreds place canbe filled by 2,3,5,7,8,9

number of ways=6

thousands place can be filled by 2,3,5

in march, veronica walked 12 miles every day. in april, she increased her daily walking distance by 10%, in may, she added 10% t

masya89 [10]

First, find what 110% of 12 is by multiplying 12 by 1.1 (13.2).

Second, find what 110% of 13.2 is by multiplying 13.2 by 1.1 (14.52).

The answer is 14.52 miles each day in May.

$\bf [sin(x)-1][sin(x)+cos^2(x)]\\\\
-------------------------------\\\\
sin^2(x)+sin(x)cos^2(x)-sin(x)-cos^2(x)
\\\\\\\
[sin^2(x)-cos^2(x)]+[sin(x)cos^2(x)-sin(x)]
\\\\\\
-[cos^2(x)-sin^2(x)]-[sin(x)-sin(x)cos^2(x)]
\\\\\\
-[\stackrel{cos(2x)}{cos^2(x)-sin^2(x)}]-sin(x)\stackrel{sin^2(x)}{[1-cos^2(x)]}

-cos(2x)-sin(x)sin^2(x)\implies -cos(2x)-sin^3(x)$

Alice has 1/5 as many miniature cars as Sylvester has Sylvester has 35 miniature cars how many miniature cars does alic have?

const2013 [10]

The answer is 7. Since Alice has 1/5 as many cars as Sylvester. You multiply 1/5 by how many cars Sylvester has. Sylvester has 35 cars, so you would do 35 times 1/5 or 35 divided by 5 (multiply by 1/5 and divided by 5 are the same thing) and you would get your answer of 7.
