Jade spent ⅓ of her math homework time working on word problems. What fraction of an hour did she spend working on word problems
Tems11 [23]

Answer:

If total maths hw time = 90 minutes, time spent on word problems = 1/2 hour

Step-by-step explanation:

Let the time available for maths homework be = 90 minutes. It is equal to 1.5 hour (as 1 hour = 60 minutes, 0.5 hour = 30 minutes).

1/3rd of maths homework time, ie 1/3rd of 90 minutes = 30 minutes, is used in doing word problems. These 30 minutes correspond to half (1/2 or 0.5) of an hour, as 1 hour = 30 minutes.

Look at this graph:
o-na [289]
<h2>Answer:</h2>

The Slope is \frac{2}{3}\\

<h2>Explanation:</h2>

Notice that both the points, (0,20) and (20,50), are on the line. So we can use those points to calculate the slope. Recall that that slope of the line m can be calculated by \frac{y_2 -y_1}{x_2 -x_1}\\ if we have the points, (x_1,y_1) and (x_2,y_2).

<h3>Calculating for the slope of the line:</h3>

Given:

(0,20)

(20,50)

m = \frac{50 -20}{20 -0} \\ m = \frac{30}{20} \\ m = \frac{2}{3}
