What is the volume of a rectangular prism with the dimensions: base 5/ 8 cm, height 3/8 cm, and length 7/8 cm?
A) 15/1024 cm3
B) 15/512 cm3
C) 105/1024 cm3
D) 105/512 cm3

105/512 cm³

Step-by-step explanation:

Step 1:

To find the volume of rectangular prism =

Where L=Length of Prism

           B= Base of Prism

           H= Height of Prism

Step 2:

     Here L= 7/8 cm

              B= 5/8 cm

               H= 3/8 cm

By using BODMAS rule simplification is done.

BODMAS- Brackets Orders Division Multiplication Addition Subtraction

Volume =

             =

              =  cm³

the 1st digit is in the 100s n its 1

step-by-step explanation:

3,589÷18 = 199.389

so the first digit of the quotient is in the 100s n its 1

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!
