Answer:
250 in²
Step-by-step explanation:
There are four identical rectangles so therefore area of one rectangle times 4. Then add the sum of the areas of the two identical squares.
4( l x b) + 2( l x b)
4( 10 x 5) + 2(5 x 5)
4(50) + 2(25)
200 + 50
Therefore 250 in²
1.80 divided by 7 would give you .257 but if you round it, it's.26
Answer:
a=21.1
Step-by-step explanation:
You can use the given (incorrect) equation and fill in the value of t to find h:
h = 12.5 +9sin(750(3.5)) = 3.68 . . . . feet
__
Or, you can use the correct equation, or just your knowledge of revolutions:
h = 12.5 +9sin(750(2π·3.5)) = 12.5 . . . . feet
in 3.5 minutes at 750 revolutions per minute, the propeller makes 2625 full revolutions, so is back where it started — at 12.5 feet above the ground.
Answer:
Step-by-step explanation:
3x +4y= 8, where y =8x-20
3x + 4(8x - 20) =8
3x + 32x - 80 =8
3x +32x =8 +80
35x =88
x=88/35
x= 2.514
Answer:
11.66
Step-by-step explanation:
