martha builds bookcases. the selling price of each is determined by the cost of each oak board and the cost of each mapleboard used to build the bookcase. martha finds the total cost of 4 oak boards and 12 oak boards and multiplies that cost by 1.5 to determine the selling price of each bookcase. the cost per oak board is always twice the cost of each maple board. enter an equation for the selling price, s, of each bookcase based on the cost of a single maple board, m.

it has changed from the width and the height.

step-by-step explanation:

no i do not : ( what is it?

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
