area of a square field is 1600 square metre. find the cost of boundary wall if the rate of per metre is Rs. 500​

Answers

Answer 1

Answer:

Rs. 20,000

Step-by-step explanation:

the boundary wall will act as a perimeter.

the perimeter of a square field is 4S( S = side)

S x S = area

S2 = area

S =

square root of S2= square root of area

square root of S2 = S

S = square root of area

S = square root of 1600

S = 40m

perimeter = 4 x S

                 = 4 x 40

                 = 160m

1m = rs. 500

40m = 40m x rs.500

                     1m

=Rs. 20,000

Answers

Answer:

15

Step-by-step explanation:

-5 x 15 = -75

This is according to the rule -a ÷ a = -a and -a x a = -a. Where a negative divided/multiplied by a positive number equals a negative number.

-75 ÷ -5 = 15

-75 ÷ 15 = -5

How are Ratios,rates and unit rates used to solve problems?

Answers

Answer:

hope u understand

Step-by-step explanation:

Unit rates can conveniently be multiplied by any desired number in order to answer questions about differently scaled questions. E.g. If three marbles cost 30 cents, how much will eleven marbles cost?

A unit rate is a ratio such as 30 cents : 3 marbles = 10 cents per (1) marble, after doing the division.

Answer:

ratios, rates, and unit rates can be used to solve how much of something there is compared to another thing.  Ex: There are 3 times the amount of apples compared to oranges.  How many apples are there if you have 2 oranges?  For a ratio, you would make it 3:1.  Then substitute the 1 for 2.  For a rate, you would make it 3 apples per oranges.  Then do the same thing you would do for the ratio.  Unit rates work the same way.

2. What is the slope of the line that passes through the points M(-5,0) and N (6,8)?

Answers

Answer:

Hi how are you doing today Jasmine

The slope of the line that passes through the given points M(-5, 0) and N (6, 8) is [tex]\frac{8}{11}[/tex]

Given the following points:

Points on the x-axis = (-5, 6) Points on the y-axis = (0, 8)

To calculate the slope of the line that passes through the given points M(-5, 0) and N (6, 8), we would use the following formula;

The slope of a line can be defined as the gradient of a line.

Hence, a slope is typically used to describe both the direction and steepness of an equation of a straight line.  

Mathematically, the slope of a line is given by the following formula;

[tex]Slope. \;m = \frac{Change \; in \; y \;axis}{Change \; in \; x \;axis} \\\\Slope. \;m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Substituting the given points into the formula, we have;

[tex]Slope. \;m = \frac{8 - 0}{6 - [-5]}\\\\Slope. \;m = \frac{8}{11}\\\\Slope. \;m = \frac{8}{11}[/tex]

1760 upper primary pupils took part in a sports meet in 2014. This was decreased of 20% when compared to 2015. The number of the upper primary pupils who took part in 2016 increased by 5% when compared to 2015. How many upper primary pupils took part in the sports meet in 2016?

Answers

Answer:

Number of upper primary pupils who took part in the sports meet in 2016 is 1478.

Step-by-step explanation:

Total number of upper primary pupils who took part in the sports meet in 2014 is 1760. It was decreased of 20% compared to 2015.

So that,

20% of 1760 = [tex]\frac{20}{100}[/tex] x 1760

                    = 0.2 x 1760

                    = 352

Number of upper primary pupils who took part in the sports meet in 2015 = 1760 - 352

                   = 1408

Also,

5% of 1408 = [tex]\frac{5}{100}[/tex] x 1408

                  = 0.05 x 1408

                  = 70.4

Number of upper primary pupils who took part in the sports meet in 2016 = 1408 + 70.4

                           = 1478.4

With an increase of 5% compared to 2015, the number of upper primary pupils who took part in the sports meet in 2016 is 1478.

For 14/8, you first have to simply it by dividing both numbers by 2


So that it becomes 7/4, which is 1 3/4






For 48/9, divide both numbers by 3


So that it becomes 16/3 which is 5 1/3

Answer:

14/8 = 1 3/4

48/9 = 5 1/3

Step-by-step explanation:

14/8 = 1 6/8

6/8 = 3/4

14/8 = 1 3/4

48/9 = 5 3/9

3/9 = 1/3
