Apples are on sale for $0.95 per pound. Selena bought 2.8 pounds of apples. How much money did she pay for apples (round to the nearest hundredth)?

1.9

Step-by-step explanation:

2.8+0.95+1.8

$2.66

Step-by-step explanation:

2.8x.95

you set it up as a normal multiplication problem, with the decimals lining up

and put zeros in for number substitutes where there are no lined up numbers

and do the problem like a normal multiplication problem.

once you’ve got the numbers added up at the bottom you count all the spaces behind the decimal with numbers,

which will give you four

you then take the second number of your finished answer and go out four spaces

you then deduct any 0’s with no purpose

that will leave you with 2.66

i’m bad at explaining things but i hope this helped

$18 was the price of the t-shirt

step-by-step explanation:

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
