there is 4/5 lb of sand in science supplies. if one scoop of sand weighs 1/20 of a lb how many scoops of sand can maria get from
tatuchka [14]
We want to divide whole sand into scoops, so we have to divide 4/5 by 1/20. Lets do this

\frac{ \frac{4}{5} }{ \frac{1}{20} }
We know that if we want to divide 2 fraction we can multiply first by inverse of second fraction instead of dividing.,so:
\frac{ \frac{4}{5} }{ \frac{1}{20} }
\frac{4}{5}* \frac{20}{1}= \frac{4*20}{5*1}   = \frac{80}{5}= 16 scoops - its our result.

(2y+3)(3y^2+4y+5) use the chart to multiply the binomial by the trinomial
astra-53 [7]

(2y+3)(3y^2+4y+5)

so u just multiply all the things from different brackets.

2y*3y^2 = 6y^3

2y*4y = 8y^2

2y*2 = 4y

3*3y^2 = 9y^2

3*4y = 12y

3*5 = 15

so 6y^3+8y^2+4y+9y^2+12y+15

thats the answer BUT u need to collect the like terms, otherwise u probably wont get full marks on the question, so:

6y^3+17y^2+16y+15

i hope this helps :)

someone correct me if im wrong
