Answer:
105
Step-by-step explanation:
Remember PEMDAS
1/2 x 4 = 2
2 x 48 = 96
You should now have 9 + 96
9 + 96 = 105
Hey, Rhombuses and parallelograms are similar because:
~ They are both quadrilateral.
~ Sum of interior angles are 360 degrees
~ Diagonal sides of both are unequal
The answer is c

Considering balloon to be an spherical object
Volume of sphere = , where r is the radius of sphere.
After 19 minutes ,If radius of balloon changes from r to R, the Volume changes from V to V'.
V'= ,
As given,rate at which the air leaked out of the balloon (in liters of air per minute) was half of the rate at which Vavilen inflated the balloon.
Also,
Now, again the radius changes from R to r.So, Volume changes from V' to Back to V.
Time taken by the balloon to deflate = 38 minutes
But there is no relation between time and volume of Balloon.
So, we can't predict at which rate balloon is deflating or inflating.Apart from the statement given in Question:
Answer:
198
Step-by-step explanation:
2(9)(11)
Since you know that r = 9 and t = 11, you can substitute the variables to numbers. Then you just multiply to get 198. Hope this helps :)
