For this exercise, you need to use the following formula for calculate the distance between two points:

d=\sqrt[]{(x_2-x_1)^2+(y_2-y_1)^2}

The table below shows the distance d(t) in meters that an object travels in t seconds: t (seconds) d(t) (meters) 3 126 4 224 5 3
Rasek [7]
(d(5) -d(3))/(5 -3) = (350 -126)/2 = 112 . . . . . meters/second

112 m/s; it represents the average speed of the object between 3 seconds and 5 seconds

Flora used 1/5 of her flour to make some pies and 4/15 of it to bake some cakes. She also gave her friend 750g of flour. She had
MariettaO [177]

According to the information given, building and solving an expression, it is found that she used 1400 g of flour for the cakes.

<h3>How was the flour divided?</h3>
  • Her initial amount was of x.
  • She used \frac{x}{5} to make some pies.
  • She used \frac{4x}{15} to bake some cakes.
  • She gave her friend 750g, and had 850g left.

Hence, the <em>expression </em>is:

\frac{x}{5} + \frac{4x}{15} + 750 + 850 = x

x - \frac{x}{5} - \frac{4x}{15} = 1600

\frac{15x - 3x - 4x}{15} = 1600

8x = 15(1600)

x = 15(200)

x = 3000

For the cakes:

C = \frac{x}{5} + \frac{4x}{15} = \frac{3000}{5} + \frac{4(3000)}{15} = 600 + 800 = 1400

She used 1400 g of flour for the cakes.
