Answer:
Assignments finished = 7
Step-by-step explanation:
Given that:
Time taken for one assignment = 20 minutes
Time spent on working = 2 hours 20 minutes
2 hours = 120 minutes
Time spent on working = 120 + 20 = 140 minutes
Number of assignments = 
Number of assignments = 
Number of assignments = 7
Hence,
Assignments finished = 7
V= A(h/3) is the formula used for finding square pyramid.
Explanation:
In the above equation V stands for volume , A stands for base area, h stands for height. For finding the volume of square pyramid we need to follow certain steps, they are as follows:
First we need to measure all the side lengths present in the base. Secondly we need to calculate the base area , where the area of one sided square is a*a , then finally we need to multiply the base area with the height of the pyramid . To find the area of the square pyramid we use the formula-
A= a2+2a root over( a2/4+h2 )
The second one is correct
Answer:
A) 2 x 0.80= 1.60
Step-by-step explanation:
get 80 on the cents and times it by how many soda's you got (2) then times it by normal which will get you 16 so add a zero at the end to make the answer.
