Layla conducted a science experiment. She thought that she would end up with 16 milliliters of the solution, but she actually ended up with 19 milliliters of the solution. What was her percent error? Round to the nearest tenth. A.-15.8%
B.-23.1%
C.-84.2%
D.-17.4%

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse

4+4+2x

or

2x+8

step-by-step explanation:

hi there!

step-by-step explanation:

a roof pitch is basically for every inch rise there is 12 inches run.

the height of the roof is also known as the rafter.

formula: rafter^2 = rise^2 + run^2

rafter^2 = 5^2 + 12^2

rafter^2 = 25 + 144

rafter ^2 = 169"^2

the height of the roof from the lowest point to the highest point is 169"^2.

hope this : )

he answer is x=1x3 because x=1 to x=3
