Answer:

$\boxed{ \sf{Total \:Interest = \underline{ 2223} \: rupees}}$

$\boxed{ \sf{Total \: Amount = \underline{10023} \: rupees}}$

Step-by-step explanation:

<h3>♨ Given :</h3>

Principal ( P ) = 7800 rupees
Annual rate of interest ( R ) = 9.5 %
Time ( T ) = 3 years

Total interest ( I ) = ?
Total amount ( A ) = ?

<h3>✎ Finding the total interest :</h3>

$\boxed{ \sf{Simple \: interest \: ( \: I\: )\: = \frac{Principal \: ( \: P \: ) \: \times \: Time \: ( \: T \: ) \: \times \: Rate \: ( \: R \: )}{100}}}$

$\longrightarrow{ \sf{ \frac{7800 \times 3 \times 9.5}{100}}}$

$\longrightarrow{ \sf{ \frac{222300}{100}}}$

$\longrightarrow{ \sf{2223 \: rupees}}$

The total interest = <u>2</u><u>2</u><u>2</u><u>3</u> rupees.

<h3>✎ Finding the total Amount :</h3>

$\boxed{ \sf{Amount \: (A) = Principal \: ( \: P \: ) \: + \: Interest \: ( \: I \: )}}$

$\longrightarrow{ \sf{7800 \: rupees + 2223 \: rupees}}$

$\longrightarrow{ \sf{10023 \: rupees}}$

The total amount = <u>1002</u><u>3</u> rupees.

--------------------------------------------------------------

<h3>☞ Additional Info :</h3>

Principal : The money which is borrowed or deposited is called principal ( P ).
Interest : The additional amount of money which is paid by borrower to the lender is called Interest ( I ) .
Time : The duration of time for which principal is deposited or borrowed is termed as time period ( T ).
Rate : The condition under which the interest is charged is called rate ( R ).
Amount : The sum of principal and interest is called an amount ( A ).

<h3>✑ Important Formulaes :</h3>

$\sf{Interest \: = \frac{Principal \times Time \times Rate}{100}}$

$\sf{Principal = \frac{Interest \: \times \: 100}{Time \times Rate}}$

$\sf{Time = \frac{Interest \: \times \: 100}{Principal \times Rate}}$

$\sf{Rate = \frac{Interest \: \times \: 100}{Principal \times Time}}$

$\sf{Amount = Principal + Interest}$

$\sf{Principal = Amount - Interest}$

$\sf{Interest = Amount - Principal}$

Hope I helped!

Answer:

30m +50 = 20m +100
m = 5
yes. symmetric property of equality.

Step-by-step explanation:

1. The expression for c in the first equation is (30m+50). Substituting that for c in the equation ...

c = 20m +100

gives you ...

30m +50 = 20m +100

2. Adding -50-20m to both sides gives ...

10m = 50

m = 5 . . . . . . . divide by 10

3. Doing the substitution in reverse, you would substitute (20m+100) for c in the equation ...

c = 30m +50

to get ...

20m +100 = 30m +50

This is the equation of part 1 with the expressions swapped to the other side of the equal sign. The symmetric property of equality tells you that changing sides of the equal sign does not change the value of the variable(s).

You get the same solution.

ABCD is a parallelogram. What is the measure of ∠ACD?

Igoryamba

Step-by-step explanation:

Here

5x+16+7x-3+6x+5 = 180(being sum of triangle)

or, 18x=180-18

or, x= 162/18

so, x = 9

now,

here,

<ACD = <ACB(diagonals of parallelogram bisect eachother)

or, <ACD = 7x-3

or, <ACD = 7×9-3

or, <ACD = 63-3

So, <ACD = 60°

The answer for :

$h. \: \: \: \frac{5}{6}$

$i. \: \: \: \frac{35}{32}$

$k. \: \: \: \frac{-29}{20}$

$l. \: \: \: \frac{13}{15}$

Step-by-step explanation:

Question h:

$\frac{2}{3} + ( \frac{1}{3} \times \frac{1}{2} )$

$= \frac{2}{3} + \frac{1}{6}$

$= \frac{2 \times 2}{3 \times 2} + \frac{1}{6}$

$= \frac{4}{6} + \frac{1}{6}$

$= \frac{5}{6}$

Question i:

$\frac{7}{8} + \frac{1}{4} \times ( \frac{3}{2} - \frac{5}{8} )$

$= \frac{7}{8} + \frac{1}{4} \times ( \frac{3 \times 4}{2 \times 4} - \frac{5}{8} )$

$= \frac{7}{8} + \frac{1}{4} \times ( \frac{12}{8} - \frac{5}{8} )$

$= \frac{7}{8} + (\frac{1}{4} \times \frac{7}{8} )$

$= \frac{7}{8} + \frac{7}{32}$

$= \frac{7 \times 4}{8 \times 4} + \frac{7}{32}$

$= \frac{28}{32} + \frac{7}{32}$

$= \frac{35}{32}$

Question k:

$\frac{3}{4} - ( \frac{12}{7} \div \frac{12}{21} ) + \frac{4}{5}$

$= \frac{3}{4} - ( \frac{12}{7} \times \frac{21}{12} ) + \frac{4}{5}$

$= \frac{3}{4} - \frac{3}{1} + \frac{4}{5}$

$= \frac{3 \times 5}{4 \times 5} - \frac{3 \times 20}{1 \times 20} + \frac{4 \times 4}{5 \times 4}$

$= \frac{15}{20} - \frac{60}{20} + \frac{16}{20}$

$= - \frac{29}{20}$

Question l:

$\frac{5}{2} \times ( \frac{2}{3} - \frac{1}{5} ) - ( \frac{2}{5} \div \frac{4}{3} )$

$= \frac{5}{2} \times ( \frac{2 \times 5}{3 \times 5} - \frac{1 \times 3}{5 \times 3} ) - ( \frac{2}{5} \times \frac{3}{4} )$

$= \frac{5}{2} \times ( \frac{10}{15} - \frac{3}{15} ) - \frac{3}{10}$

$= (\frac{5}{2} \times \frac{7}{15}) - \frac{3}{10}$

$= \frac{7}{6} - \frac{3}{10}$

$= \frac{7 \times 5}{6 \times 5} - \frac{3 \times 3}{10 \times 3}$

$= \frac{35}{30} - \frac{9}{30}$

$= \frac{26}{30}$

$= \frac{13}{15}$
