For this type of question, you just need to multiply the percentage with the number
so, the calculation would be

47.2% x 300

47.2/100 x 300

47.2 x 3

= 141.6

The mean cost for each item in his bag was $3.05. He bought a total of 8 items, and the prices of 7 of those items are listed be

Anna007 [38]

You know the mean cost is calculated from ...

... (mean cost) = (total cost)/(number of items)

You are given the mean cost and the number of items, so you can find the total cost for the 8 items as ...

... (mean cost)×(number of items) = (total cost)

... 8 × $3.05 = (total cost) = $24.40

You are given the costs of 7 of the items so ...

... (total cost) = (8th item cost) + (total cost of 7 items)

Then we can find the (8th item cost) as ...

... (8th item cost) = (total cost) - (total cost of 7 items)

Adding up the given cost of the 7 items, we get ...

... (total cost of 7 items) = $20.57

... (8th item cost) = $24.40 -20.57 = $3.83

The price of the 8th item in the bag was $3.83.

sketch the curve represented by the parametric equations (indicate the orientation of the curve), write the corresponding rectan

pychu [463]

Answer:

Reduced equaton is $5x-3y+\frac{28}{3}=0$ .

Step-by-step explanation:

Given parametric equation is,

$x=3t-5$ and $y=5t+1$

Now, $x=3t-5\implies t=\frac{x+5}{3}$ substitute in second equation we get,

$y=\frac{5}{3}(x+5)+1$

$y=\frac{5}{3}x+\frac{28}{9}$

$\implies 5x-3y+\frac{28}{3}=0$

which is the corresponding rectangular equation after eliinating the parameter.

Now consider,

$y=\frac{5}{3}x+\frac{28}{9}$

Of which,

Slope : $\frac{5}{3}$

when,

$x=0, y=\frac{28}{9}=3.1$

$x=1, y=\frac{43}{9}=4.8; x=-1, y=\frac{13}{9}=1.4$

$x=2, y=\frac{58}{9}=6.4; x=-2, y=\frac{-2}{9}=-0.2$

$x=3, y=\frac{73}{9}=8.1; x=-3, y=\frac{-17}{9}=-1.8$

$x=4, y=\frac{88}{9}=9.8; x=-4, y=\frac{-32}{9}=-3.6$

$x=5, y=\frac{103}{9}=11.4; x=-5, y=\frac{-47}{9}=-5.2$

ans so on. Thus sketching th curve will look like given,
