HELP YOU ONLY NEED TO DO LIKE THREE QUESTIONS questions at bottom. Figures and cross section

Using a cereal box, find the surface area and the box's volume. The dimensions are 8 inches wide by 12 ⅛ inches tall by one ¾ inch deep. Parallel to the base, it would be a rectangle 8 inches x 1 ¾ inches.

Surface area = 2x(12 ⅛ x8) + 2 x (8 x 1 ¾) =2 x ( 12 ⅛ x 1 3/4 ) = 194 + 28 + 42 7/16 = 264 7/16 square inches.

Surface area if scaled up by a factor of 10: 10^2 = 100. 26,443 ¾ square inches.

Volume = 8 x 12 ⅛ x 1 ¾ = 169 ¾ cubic inches.

Volume scales down by 1/10
⅓^10 =3 ⅓
⅓ = 100/3 divided by 3 = 3/100

Please give measurements for Length = Width = Height =
of the cereal box. Describe the cross section of the box

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.

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!
