Answer:
30
Step-by-step explanation:
There are 6 ways the president can be chosen. Assuming the vice-president must be a different person, there are then 5 possibilities for that office. The total number of possible choices is ...
6 × 5 = 30
_____
Each of the 6 president choices can have any of 5 different vice-president choices.
Answer:
20
Step-by-step explanation:
If 36 boys can conplete a task in 4 hours, then 19.35 boys could do it in 2 and a fourth hours.
You can set up an equation
A fourth of an hour is 15 minutes, so,
36 is to 4 as x is to 2.15, or,
36=4 as X=2.15
Multiply 2.15 by 36 (77.4)
77.4 divided by 4= 19.35.
Of course, you cannot have 19.35 boys, so there must be 20.
Hope this helps!
Answer:
2530 has no units
Step-by-step explanation:
In order to understand the units from a linear equation we need to understand the general equation of a line which is:
y=mx+b where:
m=slope of the line
b=y-intercept.
Comparing the given equation with the general line equation, we noticed that 2530 represents the slope of the line.
Since the slope can be obtained by:
m=(y2-y1)/(x2-x1) whatever the units are, the slope is dimensionless, which means that 2530 has no units.
