Answer:
<h3>28 4/7 % ≈ 29%</h3>
Step-by-step explanation:
4 kg - weight of sugar
10 kg - mass of water
4kg + 10kg = 14kg - weight of the syrup
The sugar is 2/7 of the weight of the syrup.
Convert to the percentage:
Answer:
16,242. 7 cm^3.
Step-by-step explanation:
We need to cut off a square piece at the 4 corners of the cardboard.
Let the length of their edges be x cm.
The volume of the box will be:
V = height * width * length
V = x(100-2x)(40-2x)
V = x(4000 - 200x - 80x + 4x^2)
V = x(4x^2 - 280x + 4000)
V = 4x^3 + - 280x^2 + 4000x
Finding the derivative:
dV / dx = 12x^2 - 560x + 4000 = 0 ( when V is a maxm or minm.)
4(3x^2 - 140x + 1000) = 0
x = 37.86, 8.80.
Looks like x = 8.80 is the right value but we can check this out be looking at the sign of the second derivative:
V" = 24x - 560, when x = 8.8 V" is negative so this is a Maximum for V.
So the maximum volume of the box is when x = 8.8 so we have
V = 8.8(100-2(8.8)(40 - 2(8.8)
= 16,242. 7 cm^3.
Answer:
look id k which ans u want I m telling both
#5 such number could be <em><u>0</u></em> becoz it is not whole integer or positive
#6 there could be many numbers like
8.67676767.....
or
8.111111111111
etc....
Answer:
Step-by-step explanation:
Using the formula for Laplace the transformations if 
is the converted function then
To solve that integral you need to use integration by parts, when you do integration by parts you get that
