I'm assuming that the lower case c and the upper case C are the same variables.
6C^2 + 2.5D - D + 2C^2 - 3D = 8C^2 - 1.5D
Answer:
There are 320 mL in 2 cans
Step-by-step explanation:
Since one can holds 160 mL of orange juice, all we need to do is add them together since it is to cans to get 320 mL.
The first way is distributive property of multiplication. 3/5*9=3/9÷5/1=27/5. 3/5*1/2=3*1/5*2=3/10. Then you add the products and you would get 57/10. Simplify 57/10 to 5 7/10. Second way, converting the mixed fraction to a improper fraction and then multiply. 9 1/2=9*2+1÷2=19/2. 3/5*19/2=3*19/5*2=57/10. Like I said before, 57/10 simplified is 5 7/10. The last way is use rounding of fractions to estimate the products, 3/5*9 1/2. Round 9 1/2 to 10. 3/5*10=3*10/5. 30/5=6, which means that 6 is the estimated product of rounding. Hoped I helped. :)
Circumference of a circle=diameter times pi
50.24=d(3.14)
d=16
radius is half of diameter so radius is 8
Area of a circle=pi(r^2)
(3.14)(8^2)=(3.14)(64)=200.96
