Hassan sells fruit and vegetables at the market.

Juli2301 [7.4K]

Answer: 950 kg

Step-by-step explanation:

Given

Hassan sells a total of $1.33\ \text{tonnes}$ of vegetables

The ratio of the mass of fruit to the vegetables is $5:7$

Suppose $x\ \text{tonnes}$ is the total mass of stuff

For vegetables, we can write

$\Rightarrow x\times \dfrac{7}{5+7}=1.33\\\\\Rightarrow x=1.33\times \dfrac{12}{7}=2.28\ \text{tonnes}$

For fruits

$\Rightarrow 2.28\times \dfrac{5}{5+7}=0.95\ \text{tonnes}\approx 950\ kg$

What is the volume of a cube with<br> inch sides?<br> 2<br> 1

son4ous [18]

Answer/Step-by-step explanation:

The given park of sugar cubes has has 24 cubes of sugar.

The cube of sugar has equal side length of ½ in.

Volume of the park of sugar cubes = 24 * volume of 1 cube of sugar

Volume of 1 cube of sugar = $\frac{1}{2} * \frac{1}{2} * \frac{1}{2}$

= $\frac{1}{8} in^3$

Volume of the park of sugar cubes = $24 * \frac{1}{8} = \frac{24}{8} = 3 in^3$
