Answer:
Step-by-step explanation:
m<5+m<4=180
4x+12+2x=180
6x=180-12
6x=168
x=28
m<5=4x+12
m<5=4*28+12=124
Answer:
The probability is 
Step-by-step explanation:
From the question we are told that
The number of members is n = 15
Generally the number of ways of selecting two member from the fifteen members is mathematically represented as

Here C stands for combination hence we will be making use of the combination functionality in our calculator

=> 
=> 
Gnerally the number of outcome that matches the outcome required by the committee(Which is reselecting the member who where the chairman and vice chairman of the board ) is m = 1
Generally the probability of randomly selecting the two members who currently hold the positions of chairman and vice chairman and assigning them to their current positions is mathematically represented as

=> 
=>
=>
You answer is 152
Step by step:
Divide it into 2 rectangles

2nd rectangle 12x6=72
80+72=152
Answer:
90 people
Step-by-step explanation:
Total: $775
DJ: $250
Cake: $75
Unknown party guests each getting $5
Let the unknown be x
We can form an equation; <em>DJ + Cake + x number of party guests = $775</em>
<em>250 + 75 + 5x = 775</em>
<em>325 + 5x = 775</em>
Subtract 325 from <u>both sides of the equals sign</u>.
<em>5x = 450</em>
Make <em>x</em> the subject and divide both sides by 5
<em>x = 90</em>
There were 90 party guests.
191200 / 24 hours in a day = 7966.67 people per hour
60 minutes in 1 hour
7966.67 / 60 = 132.78 people per minute round to 133 people
