Perform the operations and write the answer in simplest form 2 2/5 + 3 1/4
iragen [17]

Answer: 2 2/3


Step-by-step explanation:

we have to turn this into a improper fractions first (so its something like a bobble-head)

(2 2/5) 5 x 2 = 10 + 2 = 11/5

(3 1/4) 3 x 4 = 12 + 1 = 13/4

Then add those two.

11/5 + 13/4

11 + 13 = 24

5 + 4 = 9

 so now its time to put it in simplest form 8/3

Now 8 divided by 3...BUT WAIT...3 can't go into 8

Now we turn it into a Mixed Number 2 2/3

Help please!!!!!!!!!!!!!!!!!!!!!!!!

I would say y = sin(x + 2).

Why?

1. Is it the sine function for sure.

2. The function y = sinx is moved two places to the right as indicated by the +2.

3. The function y = sin(x + 2) crosses the point (2,0).

Answer:

469.42 ft²

Step-by-step explanation:

  • Law of sines;

         w/sin27 = 38/sin40

                   w = sin27*38/sin40

                    w = 26.84 ft

  • Angle x;

            ∡X = 180 - 27- 40 = 113º

  • Area;

              A = 0.5*(26.84)*(38)*sin(113)

            A = 469.42 ft²
