Sabrina is building a rectangular raised flower bed. the boards
on the two shorter sides are 6 inches thick, and the boards on
the two longer sides are 4 inches thick. sabrina wants the outer
length of her bed to be 4 times its height and the outer width to
be 2 times its height. she also wants the boards to rise 4 inches
above the level of the soil in the bed. what should the outer
dimensions of the bed be if she wants it to hold 3136 cubic
inches of soil?

step-by-step explanation:

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
