38. 8•4 =32cm^2
39. 8+8+5+5=26 cm^2
40. Pi•r*2 so = 28.27in^3
41. 15/2=7.5 so pi•7.5^2 so area is 176.71m^3
Answer:
B) 454.50
Step-by-step explanation:
-25.50 + 480.00 = 454.50
Answer:
depending on what your using these are the answers to what I got:
Addition: 2 1/2
Multiplication: 135/256
Division: 2 2/5
Step-by-step explanation:
1 1/8 + 3/4 + 5/8 = 5
/2 = 2 1/2 = 2.5
or
1 1/8 x 3/4 x 5/8 = 135/256 = 0.527
or
1 1/8 ÷ 3/4 ÷ 5/8 = 12/5 = 2 2/5 = 2.4
Answer:
Sin 21 = p/b
0.358 = 5.5 / x
x = 5.5 / 0.358
therefore , x = 6.97
Step-by-step explanation:
Use sin formula
which is perpendicular/ base
just put the value
Answer:
2x^2t + 7xy
Step-by-step explanation:
I'm guessing you want this simplified, since you have not specified what to do,
5xy + 2xy = 7xy
-x^2t + 3x^2t = 2x^2t
= 2x^2t + 7xy
