15. If one apartment requires 36 square yards of carpeting, how many square yards of carpeting do 25 identical apartments requir
julia-pushkina [17]
For number 15, all you need to do is multiply 36 by 25 which gets you 900 square yards. For #16, you would also want to use multiplication, 3 * 39 ($117) , 4 * 15 ($60) and 27 * 2 ($54). Now add them together, 54 + 117 = 171 + 60 = $231. And finally break down the number 309 million, 058 thousand, 304 hundred. Four, eight and, nine need to be in the ones place. So you have 309,058,304, C.

Which set of angles listed are supplementary
jolli1 [7]

Answer:

A. <BED and <DEA, <AEC and <BEC

Step-by-step explanation:

Supplementary angles add up to give 180°.

m<BED = 90°

m<DEA = 90°

m<BED + m<DEA = 180°

Therefore, <BED and <DEA are supplementary.

m<AEC = 90°

m<BEC = 90°

m<AEC + m<BEC = 180°

Therefore, <AEC and <BEC are supplementary.
