Answer:
Please see the attached pictures.
Lets split the box in pieces and then add:
top = 20*15 = 300
sidesA = 2*20*9 = 360, is multiplied by 2 cause there are 2 sides like this
sidesB = 2*9*15 = 270, is multiplied by 2 cause there are 2 sides like this
so in total we have:
total = 300 + 360 + 270 = 930 cm^2
if we express this quantity in mm^2 we have:
<span>1cm² = 100 mm²</span>total = 930*100 = 93000 mm^2
so if the tiles are 5 mm^2 we need:
total tiles = <span>93000/5 = 18600
we need 18600 tiles of 5 mm^2</span>
Q + r + s.....q = 46, s = 54
46 + r + 54
100 + r <==
Answer:
∠1 and ∠3 as well as ∠5 and ∠7 are corresponding
∠2 and ∠7 are alternate

Answer: D
<u>Step-by-step explanation:</u>
Let x represent the score on her next test
78 + 92 + 88 + 89 + x = 5(90)
347 + x = 450
<u> -347 </u> <u>-347 </u>
x = 103
