Answer:
2.18
Step-by-step explanation:
We will use angle A to solve this and tangent. Tangent in equal to opposite divided by adjacent. In relation to angle A, the opposite side is 6 units and the adjacent side is AC, which we want. This can be set up as
tan70=6/x (x is representing AC)
(x)tan70=6
x=6/tan70
x=2.18
The rate of change of item ll is greater than the rate of change of item l (B).
Answer:
7 tins of paint
Step-by-step explanation:
Surface Area of a Cylinder: 2(3.14)(r)(h) + 2(3.14)(r^2)
Radius: 0.7m
Height: 1.9m
Plug them in:
SA: 2(3.14)(0.7)(1.9) + 2(3.14)(0.7^2)
SA: 6.28(1.33)+6.28(0.49)
SA: 8.3524 + 3.0772
SA: 11.4296
Surface Area of Each Tank: 11.43m^2
11.43^2 x 3 = 34.29m^2
34.29m^2/5m^2 = 6.858 tins of paint rounded to 7 since you can't have 6.858 tins of paint
88.9 is close to 9015.1 is close to 15The idea of an estimate is to do the math without a calculator. 90 / 15 is roughly 6.
There is something I should say that is critical. If you figure out the exact answer of 5.88, you are likely going to get it wrong. This question asks you to round before you do a division. That's what estimate means.
