So, in the list of numbers, 8 and 9 are solutions
The answer is the second option.
Answer:
128 cubes can fit in.
Step-by-step explanation:
We are given: Volume of rectangular prism = 2 units³ and Cube with edge = 1/4 unit
We must find: The number of cubes that can fill the prism
Firstly, find the volume of 1 cube:
Volume = 1/4 x 1/4 x 1/4
Volume = 1/64 units³
Next find the number of cubes that can go into the prism:
Number of cubes = 2 ÷ 1/64
Number of cubes = 128
Therefore 128 cubes can fit in.
Ax + b = r
subtract ax from both sides:-
ax - ax + b = r - ax
b = r - ax (answer)
Answer:
300 minutes
2:00 p.m
Step-by-step explanation:
Given the following:
Time taken to mark a script :
Mrs Kanja = 5mins
Miss Kanene = 4mins
Mrs Nyaga = 12 mins
Number of scripts = 160
Start time = 9:00 a.m
Rate at which each of them mark:
Mrs Kanja = t / 5
Miss Kanene = t/4
Mrs Nyaga = t/12
Combined rate :
t/5 + t/4 + t/12 = 160
(12t + 15t + 5t) / 60 = 160
32t / 60 = 160
32t = 160 * 60
32t = 9600
t = 9600 / 32
t = 300 minutes
300 minutes = 300/60 = 5hrs
9:00 a.m + 5 hours = 2:00 p.m
