Answer:
171.85 cm
Step-by-step explanation:
Given data
We are given that the distance = 149 cm 415in
Let us mark the units uniform by converting inches to cm
1 inches = 2.54cm
415 inches= x cm
cross multiply
x= 415*2.54
x= 1054.1 cm
Hence the total distance in cm is 1054.1+149= 1203cm
If in 7 days he travels 1203cm
in 1 day he will travel x cm
cross multiply
7x= 1203
divide both sides by 7
x= 1203/7
x= 171.85 cm
Answer:
21. Vol. = L ^ 3
or, 27000 = L ^ 3
or, cube root undefr 27000 = L
Therefore, Edge length = 30 cm
22.
a. v = l ^ 3
or, 64000 = l ^ 3
or, cube root under 64000 = L
or, l = 40 cm
Also,
surface area = 6 a ^ 2
= 6 * 40 ^ 2
= 6 * 1600
= 9600 cm ^ 2 #

The pic has 4 lines of symmetry and has rotational symmetry
Angle of rotation = 360/4 = 90 degrees
7x7x7, I think so not entirely sure. But 7³ is 7x7x7 it's not 7x3
If order mattered, then there would be 6*5*4*3 = 30*12 = 360 different ways to form the committee. However, no single member outranks the other. Each member has equal ranking. So order does not matter.
Since order does not matter, we must consider all of the ways to arrange a single group of 4 people. That is 4! = 4*3*2*1 = 24 ways. We overcount by a factor of 24 when order doesn't matter which is why we divide the previous result (360) by 24 to get 360/24 = 15
Answer: 15
Note: you can use the combination formula n C r = (n!)/(r!*(n-r)!) with n = 6 and r = 4 to get the same answer
