Step-by-step explanation:
We know that area of Trapezium =

1/2 * (16+48) * 20
= 640 m²
Now, for semicircle,
1/2 * pi * r²
= 1/2 * 3.14 * 18.86 * 18.86
= 558.44 m²
Adding both,
1198.44 m² ~ 2000 m²
Hope it helps :)
Answer:
There will be 200 calories
Step-by-step explanation:
300 divided by 3 = 100
100 multiplied by 2 = 200
Let

Then

and solving for x gives






By the quadratic formula,

but x must be a positive number, so only the positive square root solution is valid.

We identify a = c = 3 and b = 2, so a + b + c = 8.
Answer:
(csc c-cot c) ^2
Step-by-step explanation:
Answer:
Number of pineapples= 10
number of pears = 19
number of kiwis = 10 -2 = 8
Step-by-step explanation:
Cost of a pear = $ 0.50
Cost of a pineapple = $ 1.5
cost of a kiwi = $ 0.3
Let the pineapples = p
Number of pears = 9 + p
Number of kiwis = p - 2
The cost is
0.15 p + 0.5 (9 + p) + 0.3 (p - 2) = 13.50
0.15 p + 4.5 + 0.5p + 0.3 p - 0.6 = 13.50
0.95 p = 9.6
p = 10
