We have to solve two inequations:
Equation 1:
30(x-1)≥0
(x-1)≥0/30
(x-1)≥0
x≥1 (solution 1)

Equation 2:
5x²≥0
x≥0

The solution is: solution1 <span>∩ solution2

What is the percentage… b of sugar in the syrup made of 10 kg of water and 4 kg of sugar?

Artist 52 [7]

Answer:

Step-by-step explanation:

4 kg - weight of sugar

10 kg - mass of water

4kg + 10kg = 14kg - weight of the syrup

$\dfrac{4kg}{14kg}=\dfrac{2}{7}$

The sugar is 2/7 of the weight of the syrup.

Convert to the percentage:

$\dfrac{2}{7}=\dfrac{2}{7}\cdot100\%=\dfrac{200}{7}\%=28\dfrac{4}{7}\%\aaprox29\%$
