7.

A 4 m wide path runs around a feild of length 13 cm and width 85 find the area of path.

Answer»

en

Length of FIELD= 130 m
Breadth of Field= 85 m
Path wide = 4m

To Find

Area of Path

Solution

Area of Field= length× Breadth

Area of Field= 130× 85

Area of Field= 11050 m²

NEW length = 130m+4m+4m=138m
New Breadth= 85m+4m+4m= 93m

New Area of Field= length× Breadth

New Area of Field= 138m×93 m

New Area of Field=11926 m²

Area of path= New Area of Field - Area of Field

Area of path= 12834 - 11050

Area of path= 1784 m²

13.	Peter bought a shoe whose marked price is Rs. 1800. The shopkeeper gives 12% discount in that purchase. Find the final amount Peter has to pay
Answer» ONG>Answer : P> ₹1,584 Explanation : Peter bought a shoe whose marked price is ₹1,800. The shopkeeper gives 12% discount in that purchase. Find the amount Peter has to pay. M. P. (marked price) of the shoe ₹1,800 Discount given by the shopkeeper 12% We KNOW that, S. P. (selling price) = (100 - discount)/100 × M. P. ∴ S. P. = (100 - 12)/100 × 1,800 → 88/100 × 1,800 → 88 × 18 → 1,584 ∴ Peter has to pay ₹1,584 for the shoe.

Peter bought a shoe whose marked price is Rs. 1800. The shopkeeper gives 12% discount in that purchase. Find the final amount Peter has to pay

Answer» ONG>Answer : P>

₹1,584

Explanation :

Peter bought a shoe whose marked price is ₹1,800. The shopkeeper gives 12% discount in that purchase. Find the amount Peter has to pay.

M. P. (marked price) of the shoe ₹1,800

Discount given by the shopkeeper 12%

We KNOW that,

S. P. (selling price) = (100 - discount)/100 × M. P.

∴ S. P. = (100 - 12)/100 × 1,800

→ 88/100 × 1,800

→ 88 × 18

→ 1,584

∴ Peter has to pay ₹1,584 for the shoe.

19.

Find the circumference of the circles ⭕ whose diameter is.

Answer»

ong>Answer:

Step by step explanation:

1.(i) Diameter = 84 cm
So, Radius = 84/2 = 42 cm
Circumference = 2πr = 2*22/7*42 = 44*6 =264 cm
(ii) Diameter = 91 cm
Radius = 91/2 = 45.5 cm
Circumference = 2πr = 2*22/7*45.5 = 44*6.5 = 286 cm
(iii) Diameter = 42 cm
Radius = 42/2 = 21 cm
Circumference = 2πr = 2*22/7*21 = 44*3 = 132 cm
(IV) Diameter = 21 cm
Radius = 21/2 = 10.5 cm
Circumference = 2πr = 2*22/7*10.5 = 44*1.5 = 66 cm
(v) Diameter = 56 cm
Radius = 56/2 = 28 cm
Circumference = 2πr = 2*22/7*28 = 44*4 = 176 cm
2.(i) Radius = 5.6cm
Circumference = 2*22/7*5.6 = 44*0.8 =35.2 cm
(ii) Radius = 4.9 cm
Circumference = 2*22/7*4.9 = 44*0.7 =30.8 cm
(iii) Radius = 6.3 cm
Circumference = 2*22/7*6.3 = 44*0.9 = 39.6 cm
(iv) Radius = 8.4 cm
Circumference = 2*22/7*8.4 = 44*1.2 =52.8 cm
(v) Radius = 4.2 cm
Circumference = 2*22/7*4.2 = 44*0.6 = 26.4 cm

The given scores in ascending order is - 72, 84, 89, 95, 100. $\longrightarrow$ Mean = $\dfrac{\text{<klux>SUM</klux>\:\:of\:\:all\:\:observations}}{\text{Total\:\:no.\:\:of\:\:observations}}$ Here, Sum of all observations = 72 + 84 + 89 + 95 + 100 = 440 Total number of observations = 5 So, $\longrightarrow$ Mean of the given data = $\dfrac{440}{5} = 88$ Now, finding the median, $\longrightarrow$ Median = $\left(\dfrac{n+1}{2}\right)th\:\:term$ Here, n = Total number of observations = 5 So, $\longrightarrow$ Median = $\left(\dfrac{5+1}{2}\right)th\:\:term= \left(\dfrac{6}{2} \right)th\:\:term=\left(3 \right)th\:\:term=89$ $\star$ The relationship between Lakeisha's mean and median quiz score is that the median of her scores is 1 GREATER than the mean of her score.

The following data shows Lakeisha's scores of five math quizzes. 100, 89, 84, 72, 95 What is the relationship between Lakeisha's mean and median quiz score?

Answer»

em>Given :-

Lakeisha's scores of five math quizzes -

100, 89, 84, 72, 95

To FIND :-

The relationship between Lakeisha's mean and median quiz score

Solution :-

First we have to arrange the given data in ascending or descending order.

The given scores in ascending order is -

72, 84, 89, 95, 100.

$\longrightarrow$ Mean = $\dfrac{\text{<klux>SUM</klux>\:\:of\:\:all\:\:observations}}{\text{Total\:\:no.\:\:of\:\:observations}}$

Here,

Sum of all observations = 72 + 84 + 89 + 95 + 100 = 440

Total number of observations = 5

So,

$\longrightarrow$ Mean of the given data = $\dfrac{440}{5} = 88$

Now, finding the median,

$\longrightarrow$ Median = $\left(\dfrac{n+1}{2}\right)th\:\:term$

Here,

n = Total number of observations = 5

So,

$\longrightarrow$ Median = $\left(\dfrac{5+1}{2}\right)th\:\:term= \left(\dfrac{6}{2} \right)th\:\:term=\left(3 \right)th\:\:term=89$

$\star$ The relationship between Lakeisha's mean and median quiz score is that the median of her scores is 1 GREATER than the mean of her score.
