$140 ÷ 18 = $7.7777
rounded = $7.78 per square foot
NOT SURE WHAT YOUR QUESTION WAS EXACTLY SO GAVE YOU SOME OPTIONS
or $140 for 18ft² = $140 for 324ft
or $140 ÷ 324ft = $0.43 per foot
Answer:
426+17m=s
Step-by-step explanation:
You are multiplying 17 by an amount of months (m) then adding 426 dollars to that because it is the amount of money you started with. s means the total savings which is what you'll get by solving the equation once you know how many months you've been saving.
23-8= 15 degrees it increased by 15 degrees
We know that
the law of cosines establish
b²=a²+c²-2*a*c*cos B
in this problem
a=4 units
c=5 units
B=60°
so
b²=a²+c²-2*a*c*cos B
b²=4²+5²-2*4*5*cos 60°
b²=16+25-40*(1/2)
b²=16+25-20
b=√[16+25-20]
the answer is
b=√[16+25-20]
