Let 'x' represent the number of baskets and let 'y' be the total cost.

Since the paint costs 14.50 and each basket cost 7.25, then we have the following function:

y=7.25x+14.50

To find the cost of 4 baskets, we can make x = 4 and solve for y:

\begin{gathered} x=4 \\ \Rightarrow y=7.25(4)+14.50=29+14.50=43.50 \\ y=43.50 \end{gathered}

therefore, the cost of painting 4 baskets is $43.50

Answer: 15\times\frac{1}{2}

Explanation:

Multiplying by 1/2 is the same as dividing by 2.

For example, if you have 10 slices of cake and 2 friends, then each friend gets 10/2 = 5 slices. We could also say 10\times \frac{1}{2} = 5

The fraction 1/2 converts to the decimal form 0.5, which means 10 \times \frac{1}{2} = 10*0.5

1.Find the compound interest on Rs25000 for 3 years at 10% per annum ,Compounded annually.
LekaFEV [45]

Answer:

The compound interest is Rs8275

Step-by-step explanation:

The rule of the compound interest is A = P(1+\frac{r}{n})^{nr}, where

  • A is the new amount
  • P is the initial amount
  • r is the interest rate in decimal
  • n is the number of periods
  • t is the time

The interest I = A - P

∵ The amount of investment is Rs25000 for 3 years

∴ P = 25000

∴ t = 3

∵ The rate of interest is 10% per annum, compounded annually

∴ r = 10% = 10 ÷ 100 = 0.1

∴ n = 1 ⇒ compounded annually

→ Substitute these value in the 1st rule above to find the new amount

∵ A = 25000(1+\frac{0.1}{1})^{1(3)}

∴ A = 25000(1.1)^{3}

∴ A = Rs33275

→ Use the 2nd rule above to find the interest

∵ I = 33275 - 25000

∴ I = 8275

∴ The compound interest is Rs8275

suppose marcus delivers papers at a rate of 9 papers in 18 minutes.How much longer would it take him to deliver 100 papers than
arlik [135]


We need to write the following expression and solve for x:

9/18 = 100/x

So: 9x = 1800

x = 200

So it would take him 200 minutes to deliver 100 papers.

We do the same for 72 papers

9/18 = 72/x

so 9x = 1296

and x = 144

It would take him 144 minutes to deliver 72 papers.
