O : P => 2 : 5

<span>(a)    </span>1 liter of pop to serve 7 people

<span>=>           5 units = 1</span>

<span>               1 unit = 1 / 5</span>

Orange juice => 2 units

Hence, Orange juice needed is 2 * 1 / 5 = 0.4 liters

 

<span>(b)    </span>If 1 liter of pop is needed to serve 7 people, then we will need (1 / 7) * 15 for 15 people

i.e. 2.14 liters

 

As the ratio of O : P = 2 : 5,

<span>               5 units = 2.14</span>

<span>               1 units = 2.14 / 5</span>

 

<span>For Orange juice, we will need 2 * 2.14 / 5 = 0.856 liters for 15 people</span>

If the pattern continues how many cups of milk does George need to make 6 batches of muffins
alexdok [17]

Answer:

see explanation

Step-by-step explanation:

If we consider the differences between consecutive terms, that is

\frac{3}{4} - \frac{3}{8} = \frac{3}{8}

1 \frac{1}{8} - \frac{3}{4} = \frac{3}{8}

1 \frac{1}{2} - 1 \frac{1}{8} = \frac{3}{8}

To obtain the next term in the pattern add \frac{3}{8} to the previous term.

batches = 5 ⇒ milk = 1 \frac{1}{2} + \frac{3}{8} = 1 \frac{7}{8}

batches = 6 ⇒ milk = 1 \frac{7}{8} + \frac{3}{8} = 2 \frac{1}{4}

Find the annual rate of interest. Principal = 4600 rupees, Period = 5 years, Total amount = 6440 rupees, Annual rate of interest
Len [333]

The annual rate of interest per year is 8%

<u>Solution:</u>

Given:- Principal (p) = 4600 rupees, Time –Period (t) = 5 years, Total amount(A) = 6440 rupees

First we will calculate the Interest and then using formula of simple interest we will calculate the rate of interest

Interest = Amount – Principal

Interest = 6440  – 4600 = 1840

Now using the formula of simple Interest and on putting values we get,

\text {Simple Interest }=\frac{P \times R \times T}{100}

Where "P" is the principal and "R" is the rate of interest per annum and "T" is the time period

1840=\frac{4600 \times R \times 5}{100}

\begin{aligned} \mathrm{R} &=\frac{1840 \times 100}{4600 \times 5} \\\\ \mathrm{R} &=\frac{1840}{230} \\\\ \mathrm{R} &=8 \% \end{aligned}

Hence, the required rate of interest per year is 8%

(a) need to find the number of books, we'll call it "b". then the money (6w) minus the cost of books (17b) equals change left over (w)
6w - 17b = w
6w - w = 17b
5w = 17b
(5/17)w = b

(b) if w = 34
(5/17) *34 = b
10 = b
