The volume of globe is 381.51 cubic inches when the dimensions of the globe were reduced by half
<em><u>Solution:</u></em>
The globe is usually of spherical shape
<em><u>The volume of sphere is given as:</u></em>
Where, "r" is the radius of sphere
Given that diameter is 18 inches
Diameter = 18 inches
Thus radius is 9 inches
The dimensions of the globe were reduced by half
Thus radius is reduced by half
Now find the volume of sphere
Thus volume of globe is 381.51 cubic inches
Answer:
The total number of burritos consumed is 68 and an equation to determine the total number of burritos consumed is
Step-by-step explanation:
Let x be the total number of burritos consumed
We are given that On Tuesday, Delainey ate 16 more than 1/2 the total number of burritos consumed
So, Number of burritos ate by Delainey on Tuesday=
We are also given that Louie ate 1 less than 3/4 of the total number of burritos consumed.
So, Number of burritos ate by Louie on Wednesday =
We are given that The number of burritos Delainy ate on Tuesday is the same as the number of burritos Louie ate on Wednesday.
So,
Hence the total number of burritos consumed is 68 and an equation to determine the total number of burritos consumed is
Let the present age of student be x
Present of teacher will be 4x
After 20 years,
Age of student = x + 20
Age of teacher = 4x + 20
According to the given condition after 20 years,
x + 20 = (4x + 20)/2
x + 20 = 2x + 10
2x - x = 20 - 10
x = 10
So student's present age is 10 years while teacher's is 4 x 10 i.e 40 years.
Hope This Helps You!
