Answer:
DEF
Step-by-step explanation:
DEF is half of ABC, which means they're both similar in some way.
As we can see line DE is half of line AB (DE is 5.5 and AB is 11)
Line DF and Line EF are half of Line AC and Line BC (DF/EF is 4 while AC/BC is 8)
Answer:
$20.44
Step-by-step explanation:
first solve for the whole thing
10 x 6 = 60
now to the red part
2 x 1.5 = 3
now the blue
r^2 * pi = a
2^2 * 3.14
4 * 3.14 = 12.56
now add red and blue
3 + 12.56 = 15.56
now subtract that sum from the whole
60 - 15.56 = 44.44
now do
44.44 / 10 = 4.444
now see how much it would cost for the grass
4.444 * 4.60 = 20.4424 ≈ 20.44
it would cost $20.44 to get the grass reseeded
Answer:
I have A 43.5
Step-by-step explanation:
2n+9+5n=30 combine like terms on left side
7n+9=30 subtract 9 from both sides
7n=21 divide both sides by 7
n=3
Answer:
70
Step-by-step explanation:
Finding the common denominator is really just finding the gcf of 7 and 10. The gcf of 7 and 10 is 70. So the common denominator is 70.
