Answer:
150
Step-by-step explanation:
h = hight
s = sides
surface = 10 x 15
surface = 150
(V = 10 x 10 x 15
(V = 100 x 15)
(V = 1500)
(Base area = B)
(B = Lenght x Width)
(B = 10 x 10)
(B = 100)
See picture, this one is a little long
Equation=2m+6=72sq^2
First step would be to cancel out the 6 in the equation to isolate the m.
So 6-6=0 and you always have to apply that to the answer so 72-6 which is equal to 66.
Now the m’s are isolated. To find out the value of m them divide it by 2 to give you one solitary m, and as said before apply that to the 66.
2m/2=m & 66/2=33. The expression now reads m=33. So m=33m^2(squared)
A)
well, she has a total of 70 + 30 tiles, now she's not going to used all of them, just some.
the dark area is 8x5, so is 40 ft², and the light gray area is 8x4 or 32 ft². The total area is then 40 + 32, or 72 ft².
b)
the dark area is an 8x5 rectangle, so is 8*5 or 40, so she'll need 40 dark tiles, but she has 70, so that's fine.
the light gray area is a 8x4 rectangle, 8*4 is 32, but she only has 30 light gray tiles, so she's short 2 light gray tiles.
