All you have to do is divide the numerator by the denominator and then multiply that result with 100 like so:

(Numerator/Denominator)*100

When you enter 8/40 into the above formula, you get (8/40)*100 which calculates to:

20%

Answer:

90.8 m

Step-by-step explanation:

Pythagorean Theorem

A²+B²=C²

slant height = C

A = 19.6/2=9.8m

90.9 in to m = 2.3m

9.8²+B²=2.3²

B²=90.9²-2.3² = 8257.52

B= $\sqrt{8257.52}$ = 90.8

Please help!!! How do you count (-3y^2+5y) (4y+7)??

levacccp [35]

You must distribute each value like this:

$(-3y^2+5y) (4y+7)\\ \\ (-12y^3-21y^2+20y^2+35y)\\ \\ (-12y^3-y^2+35y)$

Hope that helps!
