Answer:2.828
Step-by-step explanation:
Given
Surface area of a cube is increased by a factor of 2 
Let the original surface area be A
such that new surface area is 2A
for volume we need to know new radius 

where r'=new radius 
r=original radius

New volume(V')

Original volume

Answer:
Here 
perimeter=76
length =4a+5
breadth=2a-3
we know,
perimeter=2(length+breadth)
76=2(4a+5+2a-3)
76=2(7a+2)
76=14a+4
76-4=14a
72=14a
72÷14=a
a=5.14
 
        
             
        
        
        
Answer:
Step-by-step explanation:
The sum of angle measures is ...
   (7x +13)° +(83 -2x)° = 141°
   5x +96 = 141 . . . . . collect terms, divide by °
   5x = 45 . . . . . . . . . subtract 96
   x = 9 . . . . . . . . . . . divide by 5
   7x +13 = 7·9 +13 = 76 . . . . . find m∠J
   m∠J = 76°
   m∠K = 141° -76°
   m∠K = 65°
 
        
             
        
        
        
Given:
w be the weight in pounds of a baby tigers.
To find:
The inequality if baby tigers can be no larger than 4 pounds.
Solution:
Baby tigers can be no larger than 4 pounds. It mean weight of baby tigers cannot be greater than 4. In other words, the weight of the baby tigers must be less than or equal to 4.
Let w represents weight in pounds and the weight of the baby tigers must be less than or equal to 4. So,

Therefore, the required inequality is  .
