Answer:
80%
Step-by-step explanation:
There are 4 shaded sections and 1 unshaded section, so five sections in total.
4 sections are shaded, so the fraction would be 4/5.
Dividing 4/5 gets you 0.8, move the decimal point two places over to get the percent (80%).
Answer:
140 weeks.
Step-by-step explanation:
We are being asked for the maximum number that can elapse without having 2 subcommitees with the same members and the same chair. Notice that the secretary is not mentioned in this statement, so we can ignore that position.
Now, the maximum number of weeks would be equal to the total possible combinations of subcommitees that can be formed from the 7 individuals commiteed, times the number of options that can sit at the chair possition.
The total possible combinations of subcommitees that can be formed from the 7 individuals can be expressed like the following expression. Notice that there is no a particular order to be considered, so we use the combination formula:
=
= 35
Now, each of the 4 individuals have the same probability of being chosen as the chair commitee. So, we have to multiply 4 times the number of possible subcommitees in order to arrive our answer:
x = 35 * 4 = 140
This would be the maximum number of subcommitees that can be formed with no subcommitees with the same members and the same chair occurring.
Answer:
Andrew takes for a shower = 720 sec
1 min =60sec
720sec=12min
Andrew takes additional min for breakfast =420 sec
420 sec = 7min

Answer:
$20.96
Step-by-step explanation:
He has $638.54 in his account and writes a check for $159.50. The amount of money he needs to stay at or above $500 is denoted by x.
638.54 - 159.50 + x >= 500
After writing a check, Malcom has $479.04 left in his account, which is below his cutoff.
479.04 + x >= 500
He must add at least x amount of dollars to his account to avoid a fee.
x >= 20.96
In order to avoid a fee, Malcom must add a minimum of $20.96 to his account.
Answer:

Step-by-step explanation:
we are given different angles
we can see that each angles have different denominators
so, firstly we will find common denominators
denominators are 1 , 2,3,4,6
so, LCD will be 12
now, we will make denominator of all terms 12








we can see that denominators are same
so, we can arrange it according to numerators as

we can replace values
and we get order as
