100(whole class is 100%) / 6060(number of students total) = any random student chance
0.0165
A) for democrats multiply chance of any random student with number of democrats
0.0165×4040=66.66666...
B) for business majors, multiply that chance with number of business majors
0.0165×1010=16.66666...
C) for both business major and democrat multiply chance with numbers of students who are both
0.0165×33=0.544...
First of all, assuming that the "ground level" is 0;
The lift is not starting from 0, so we also need to account for the extra 15 meters above the ground the lift is.
The total distance the lift would cover in the downward direction: 15+350=365m
Now, you know that the lift covers 5 m/min
Therefore, 5x=365 (ignoring units because they can complicate things)
x=365/5
x=73 minutes
Therefore, they would take 73 minutes to reach 350 m deep into the ground with a starting position 15 m above the ground.
Hope I helped :)
Answer:
First blank: $5
Second blank: $7.50
Third blank: $11.25
Fourth blank: $13.5
Fifth blank: $15.75
Sixth blank: $18.00
Step-by-step explanation:
Half a number is $2.25, so multiply 2.25 times each half.
First blank:$2.25*2=$5.00
Second blank: $2.25*3=$7.50
Third blank: $2.25*5=$11.25
Fourth blank: $2.25*6=13.50
Fifth blank: $2.25*7=$15.75
Sixth blank: $2.25*8=$18.00
Answer:
5r^2+2
Step-by-step explanation:
(4r^2 – 3r + 2) – (-r^2 – 3r) =
Distribute the minus sign
(4r^2 – 3r + 2) +r^2 + 3r =
Combine like terms
(4r^2 + r^2 – 3r+ 3r + 2) =
5r^2+2
28 BECAUSE IT CONTINUES THE PATTERN OF SUBTRACTING 4 FROMTHE AMOUNT PULLED PER GRADE
