350kg of plastic is moulded to make garden pots weighing 1 whole 2/5 kg each. How many pots are made?​
slega [8]

The number of pots made are 250

The number of pots that can be made can be determined by dividing the total weight of the plastic by the weight of pots made

Number of pots made = Weight of plastic / weight of pot made

350 ÷ 1\frac{2}{5}

Convert the mixed fraction to an improper fraction

350 ÷ \frac{7}{5}

350 x \frac{5}{7} = 250 pots

On number 5 how do you explain how you found your answer
aivan3 [116]

30 girls , 12 were selected

40 boys, 16 were selected

We can simplify these down by finding the Greatest Common Factor in both girls and boys:

30:12 .... 15:6 .... 1 : 2.5 30/12 .... 15/6 .... 2.5

40:16 .... 20:8 .... 1 : 2.5 OR 40/16 .... 20/8 .... 2.5

They are equal ratios because their most simplified ratios/fractions are equivalent

Which set of ordered pairs does not represent a function?
Irina18 [472]
<h3>Answer:</h3>

B. { (3, –2), (3, –4), (4, –1), (4, –3) }

<h3>Step-by-step explanation:</h3>

Functions are a set of points that show how dependent variables change through independent variables.

Defining a Function

In functions, each x-value is assigned to exactly one y-value. This means that x-values do not repeat. So, if there is one x-value more than once in a set, then it cannot be a function.

For example, set B has the x-value 3 and 4 repeated twice. Thus, it does not represent a function.

Graph of a Function

Functions can also be defined through a graph. Just like with coordinate points, x-values do not repeat on the graph. You can use the vertical line test to see if a graph is a function. If you can draw a vertical line at every point on a graph without it ever intersecting with the graph more than once, then it is a function.
