A conical tent is to accommodate 77 persons. Each person must have 16m³ of air to breathe. Given the radius of the tent as 7m find the height of the tent and also its curved surface area.

Answers

Answer 1
Answer:

Answer:

Total air in the tent =77×16=1232 m 3 (which is the total volume of tent) Since the tent is conical we will use some formula of cone: Volume= 31πr 2h ; Curved surface area=πrl l= slant height & r=7m Volume = 31πr 2h= 31π(7 2)h= 31 7227 2h= 3154h And we eknow that total volume is 1232m 3 So, 1232= 3154h h= 1541232×3=24m

Answer 2
Answer:

Final answer:

To solve this problem, we need to use the volume formula of a cone and equate it to the total volume of air needed by the 77 persons. Once we solve for the height, we can then determine the curved surface area of the cone using the radius and height.

Explanation:

This mathematics problem can be solved using the formula for the volume of a cone, which is given by V = 1/3 * π * r² * h where “r” stands for the radius of the base of the cone, “h” corresponds to the height, and “π” is a constant that roughly equals to 3.14. To accommodate 77 persons, with each person needing 16 m³ of air to breathe, the total volume necessary would be 77 * 16 = 1232 m³. Setting this equal to the volume of the cone formula and plugging in the given radius (r = 7 m), we solve for the height. Simultaneously, the curved surface area of a cone is given by A = π * r * l = π * r * sqrt((r²)+(h²)). We can evaluate both the height of the tent and its curved surface area applying these equations.

A fruit seller purchased 20 kg of apples at Rs 80 per kg and sold them at Rs 85 per kg. find profit and profit percent​

Answers

Answer:

Profit = Rs 100

Profit %age = 6.25%

Step-by-step explanation:

Cost Price = Rs 80

Cost Price for 20 kg = Rs 1600

Selling Price = Rs 85

Profit for 1 kg = Rs 85 - Rs 80

=> Rs 5 (For 1 Kg)

Profit for 20 kg:

=> Rs 5*20

=> Rs 100

Now Profit %age:

=> (100)/(1600)* 100

=> 0.0625 * 100

=> 6.25%

Step-by-step explanation:

profit =S.P-C.P

C.P=20×80

=Rs1600

S.P=20×85

=Rs1700

=1700-1600

=Rs 100

Ahmed spent 2/3 of his money on a burrito and a water. The burrito coast 2 times as much as the water. The burrito cost $4, how much money does Ahmed have left?

Answers

The burrito costs twice as much as water. Let's assume the water costs $w
$4=2w
w=$2 
Ahmed spent $2+$4=$6
2/3 of the total amount = $6
Total amount =$6x3/2
                      =$9
if a burritto is twice as much as water the the water is two dollars. if Ahmed spent 2/3 of his money then( 4+2=6) for burrito and water it means he had nine dollars originally so he is left with 3 dollars.  

8(3a + 7) = 8+3(6a - 6)

Answers

Answer:

a=11

Step-by-step explanation:

8(3a + 7) = 8+3(6a - 6)

24a+56=8+18a-18

24a-18a+56=8+18a-18a-18

6a+56=8-18

6a+56=-10

6a+56-56=-10-56

6a=-66

6a/6=-66/6

a=-11

Answer:

a = -11

Step-by-step explanation:

8(3a + 7) = 8+3(6a - 6)

= -11
