Answer:
The 40 ounce jar is cheaper
Step-by-step explanation:
how i did this was divide 6.00 by 30 to get 0.2 cents per ounce then 7.20 divided by 40 to get 0.18 cents per ounce so the 40 ounce jar would be cheaper, hope this helps.
When finding the third side of a scalene triangle, use Law of Cosine with its formula
c^2 = A^2+B^2 - 2AB(cosC)
Now, you just have to input all your data in the formula,
c^2 = 6^2+11^2 - 2(6)(11)(cos40degrees)
c^2 = 36+121 - 2(6)(11)(cos40degrees)
c^2 = 36+121 - 2(6)(11)(0.77)
c^2 = 157 - 101.12
c^2 = 55.88
c = square root of 55.88
c = 7.48 ft
Length of EF is 7.48 ft
0.56 as a percent is 56%.
Multiply 0.56 times 100 to get 56%.
