Answer:

25) 0.3243

26) 1.3333

27) 0.6000

28) 0.8000

29) 0.8000

Step-by-step explanation:

sin = opp/hyp

cos = adj/hyp

tan = opp/adj

25) cos X = 12/37 = 0.324324324

26) tan C = 32/24 = 1.33333333

27) sin Z = 15/25 = 0.6

28) sin A = 32/40 = 0.8

29) sin Z = 40/50 = 0.8

One week a business sold 40 shirts. White ones cost $4.95, and the printed ones cost 7.95. In al $282 worth of shirts were sold.
Tanya [424]

Answer:

12 white 28 printed

Step-by-step explanation:

x = white y = printed

x + y = 40————(1)

4.95x + 7.95y = 282————(2)

Solve for x using 1st equation

x = 40 - y Plug in for x using 2nd equation

4.95(40 - y) + 7.95y = 282 Solve for y

198 - 4.95y + 7.95y = 282

3y = 84

y = 28         Plug in for y using 1st equation

x + (28) = 40     Solve for x

x = 12

I hope this helped and please mark me as brainliest!

Find the total surface area of the net.​
Elanso [62]

Answer:

87.8 square meters

Step-by-step explanation:

First of all, find the area of the three recthangles.They are all 9m long and 3m wide. 9*3 is 27, and since there are three of them, 27*3 is 81.

To find the area of the two triangles, you could do 3*2.6. Normally, you would halve the values because they are triangles but since there's two of them it cancels out.

3*2.6 is 7.8, and adding that to the area of the rectangles gets the equation 81+7.8 which comes out to 87.8 square meters.
