A city's bus system has a red-line and a blue-line. Both a red-line bus and a blue-line bus are currently at the City Hall Station. If a red-line bus arrives at the City Hall Station every 12 minutes and a blue-line bus arrives at the City Hall Station every 10 minutes, after how many minutes will the two buses next arrive at the City Hall Station at the same time?
Answer:
5.45minutesStep-by-step explanation:
Given that the arrival time of the redline bus= 12minutes
arrival rate = 1/12 arrival per minutes
arrival time of the blueline bus= 10minutes
arrival rate = 1/10 arrival per minutes
the combined arrival rate is given by the expression
let redline be A
and blueline be B
and let the combines arrival rate be x
A+B/(A*B)=1/x
1/12+1/0=1/x
12+10/12*10=1/x
22/120=1/x
x=120/22
x=5.45minutes
solve for the variable

Which 3-D figure matches the surface area formula?
Figure A
Figure B
Figure C
Figure D
Answer:
D
Step-by-step explanation:
you mean the formula is 4×pi×r² (not 4×pi/r²), right ?
then the correct answer is the sphere (ball).
the surface area of a cylinder is
top and bottom circle area = pi×r² each = 2×pi×r² both
and the mantle is 2×pi×r×height
the surface area of a block has nothing to do with pi.
it is the sum of 6 rectangles.
the surface area of a cone is
A = πr(r + sqrt(h² + r²))
again, also depending on "hight"

Solve this inequality. 9p < -81
A.
p > 90
B.
p < -9
C.
p < -90
D.
p < 72
Answer:
B. p < -9
Step-by-step explanation:
Given inequality:
[tex]9p < -81[/tex]
divide both sides by 9:
[tex]\implies \dfrac{9p}{9} < -\dfrac{81}{9}[/tex]
[tex]\implies p < -9[/tex]
What is the solution of: 4-2x/7 - 3x+2/3
Answer:
(-27x -2)/21
Step-by-step explanation:
Perhaps you want to combine the two fractions. This is done using a common denominator.
[tex]\dfrac{4-2x}{7}-\dfrac{3x+2}{3}=\dfrac{3(4-2x)}{7\cdot3}-\dfrac{7(3x+2)}{7\cdot3}\\\\=\dfrac{3(4-2x)-7(3x+2)}{21}=\dfrac{12-6x-21x-14}{21}=\boxed{\dfrac{-27x-2}{21}}[/tex]

Calculate the probability of rolling a 1 or 2 when using two dice (order does NOT
matter). Now calculate how often a 1 or 2 appeared in the scenario above against the
total number of appearances. Explain why these two numbers are the same or different.
The probability of rolling a 1 or a 2 is P = 4/9, this means that around 4/9 out of the N times we perform the experiment, we will see a 1 or a 2.
How to find the probability?
We assume that each number has the same probability of rolling up in both dices.
So, in each dice, the probability of rolling a 1 or a 2 is 2 out of 6, or:
p = 2/6 = 1/3
And if we get these on one of the dice, we don't want them in the other,
The probability of not rolling a 1 or a 2 is:
q = 4/6 = 2/3
The joint probability is the product of the two individual probabilities:
P = (1/3)*(2/3)
But, we also need to consider the case where we don't get an 1 or a 2 in the first dice roll, and we do get it on the second dice, then there are 2 permutations, so we need to add a factor 2.
P = 2*(1/3)*(2/3) = 4/9
Now we want to find how often a 1 or a 2 appear against the total number of appearances.
If the total number of appearances is N, then in 4/9 of these, the number 1 or 2 will appear, this is:
N*(4/9) times.
