Answer: 45

Step-by-step explanation:

Harsh is part of a school cricket team, and he has scored an average of 46 runs in 5 innings. His scores in 4 of them are 46,45, 39, and 55. His fifth score is calculated as follows:

Since he made 5 innings and has an average of 46, the total scores will be:

= 46 × 5

= 230

Total of his first 4 scores will be:

= 46 + 45 + 39 + 55

= 185

5th score = 230 - 185

= 45

Answer: his score on the last one is 45.

Step-by-step explanation:

Let h represent the his score on the last inning.

Average number of runs = sum of runs/total number of innings played.

From the information given,

Average number of runs = 46

total number of innings played = 5

Sum of runs= 46 + 45 + 39 + 55 + h = 185 + h

Therefore,

46 = (185 + h)/5

Cross multiplying by 5, it becomes

46 × 5 = 185 + h

230 = 185 + h

h = 230 - 185

h = 45

A rectangular box without a lid is to be made from 48 m2 of cardboard. Find the maximum volume of such a box. SOLUTION We let x,
tatiyna

Answer:

The maximum volume of such box is 32m^3

V = x×y×z = 32 m^3

Step-by-step explanation:

Given;

Total surface area S = 48m^2

Volume of a rectangular box V = length×width×height

V = xyz ......1

Total surface area of a rectangular box without a lid is

S = xy + 2xz + 2yz = 48 .....2

To be able to maximize the volume, we need to reduce the number of variables.

Let assume the rectangular box has a square base,that means; length = width

x = y

Substituting y with x in equation 1 and 2;

V = x^2(z) ....3

x^2 + 4xz = 48 .....4

Making z the subject of formula in equation 4

4xz = 48 - x^2

z = (48 - x^2)/4x .......5

To be able to maximize V, we need to reduce the number of variables to 1, by substituting equation 5 into equation 3

V = x^2 × (48 - x^2)/4x

V = (48x - x^3)/4

differentiating V with respect to x;

V' = (48 - 3x^2)/4

At the maximum point V' = 0

V' = (48 - 3x^2)/4 = 0

Solving for x;

3x^2 = 48

x = √(48/3)

x = √(16)

x = 4

Since x = y

y = 4

From equation 5;

z = (48 - x^2)/4x

z = (48 - 4^2)/4(4)

z = 32/16

z = 2

The maximum volume can be derived by substituting x,y,z into equation 1;

V = xyz = 4×4×2 = 32 m^3
