2. The table shows the mass of fibres in 100 grams of each food item below. Food Mass of fibre (grams per 100 grams) Beans Bread
Andre45 [30]

Given that the amount of fiber in 100 grams of beans is 3.6 grams the amount of fiber consumed from  \mathbf{\frac{2}{3}} of the small tin is <u>4.8 grams</u>.

<h3>How can the amount of fiber consumed be calculated?</h3>

From the given table, we have;

Mass of fiber in 100 g of beans = 3.6 grams

Mass of beans in the small tin = 200 grams

The quantity of the beans eaten = \frac{2}{3} of the small tin

Required:

The amount of fiber to consumed from eating  \frac{2}{3} of the small tin

Solution;

Amount  \ of \ fiber \ consumed = 200 \, g \times \dfrac{3.6 \, g}{100 \, g}  \times \dfrac{2}{3}  = \mathbf{4.8 \, g}

Therefore;

The amount of fiber consumed by eating \frac{2}{3} of the small tin = <u>4.8 grams</u>

At the beginning of the day there were 90 little fish in the pond.At the end of the day there were 52 little fish in the pond.Fi
balu736 [363]

Answer:

42%

Step-by-step explanation:

The first step is to calculate the difference in the number of fishes from the beginning of the day to the end of the day.

90 -52

= 38 fishes

Therefore the percent decrease can be calculated as follows

= 38/90 × 100

= 0.422 × 100

= 42.2 %

= 42% ( to the nearest cent)

The profit P (in thousands of dollars) for an educational publisher can be modeled by P 52b31 5b21b where b is the number of wor
Anna007 [38]

Answer:

The lesser number of workbooks are 1,000

Step-by-step explanation:

The correct question is

The profit P (in thousands of dollars) for an educational publisher can be modeled by P=-b³+5b²+b where b is the number of workbooks printed (in thousands). Currently, the publisher prints 5000 workbooks and makes a profit of $5000. What lesser number of workbooks could the publisher print and still yield the same profit?

we have

P=-b^3+5b^2+b  

For P=\$5,000

substitute in the equation and solve for b

Remember that the profit and the number of workbooks is in thousands

so

P=5

5=-b^3+5b^2+b

Using a graphing tool

Solve the cubic function

The solutions are

x=-1

x=1

x=5

therefore

The lesser number of workbooks are 1,000

<u><em>Verify</em></u>

For b=1

P=-(1)^3+5(1)^2+1  

P=5  -----> is in thousands

so

P=\$5,000 ----> is ok
