Answer:
2044 cubic inches
Step-by-step explanation:
The amount of concrete required is the larger volume MINUS the smaller volume.
Note: Volume of cube = s^3 where s is the side length
Larger Volume = s^3 = 15^3 = 3375
and
Smaller Volume = s^3 = 11^3 = 1331
Hence, amount of concrete needed to make 1 planter = 3375 - 1331 = 2044 cubic inches
Answer:
length = 13 ft
Width = 3 ft
Step-by-step explanation:
Width = w ft
Length = ( w +10 ) ft
Area = 39 square ft
length * width = 39
(w +10)* w = 39
w *w + 10*w = 39
w² + 10w - 39 = 0
w² + 13w - 3w - 3*13 = 0
w(w + 13) - 3(w + 13) = 0
(w + 13) (w - 3) = 0 {Ignore w + 13 , as measurement cannot be in negative}
w - 3 = 0
w = 3
length = 3 +10 = 13 ft
Answer:
8.25
= root under (8-0)^2+(2-0)^2
= root under (8)^2+(2)^2
=root under 64+4
= root under 68
8.25 units

Answer:
Raul traveled 31.25 miles an from 1:50 to 4:20. So, subtract those, you get 2:30. Turn 2:30 into a decimal (2.30) and now divide 31.25 by 2.30. the answer is 13.59 rounded That number turned into a Fraction is about 13 miles an hour.
Step-by-step explanation:
Y=3.4x
2*3.4=6.8
5*3.4=17
8*3.4=27.2
11*3.4=37.4
