A train ride is 8 hours long every 2/3 hours the conductor checks on the passengers how many times during the trip does he check on the passenger Please show work
Answer:
The conductor checked on the passengers 12 times.
Step-by-step explanation:
To find how many times the conductor checks on the passengers, you must do
8 divided by 2/3
because you have to find how many 2/3 (times checked by conductor) are in 8 hours.
8/1 ÷ 2/3
Switch the two numbers of 2/3 or find the reciprocal which is
3/2
and change ÷ to ×
Now solve.
8/1 x 3/2 = 24/2 (8x3=24 and 1x2=2)
which Simplified is
12/1 or 12
Check your answer:
12/1 x 2/3 = 24/3 = 8
The conductor checked on the passengers 12 times.

In the third column, the sequence is: F, T, F, T
You flip whatever you see in the q column since ~q means "not q".
--------------
In the fourth column is: T, T, T, F
The general form of p -> q is false if p is true while q is false; otherwise, it is true. So ~q -> p is false when ~q is true and p is false.

7. In how many ways can 7 different flowers be arranged in a row?
find the volume of the cylinder formed when the rectangle in the figure is rotated about the x-axis.
A. 62.83 units
B. 157.08 units
C. 314.15 units
D. 31.42 units
Answer:
A
Step-by-step explanation:
that means the radius of the left and right circles is 2 units.
and the height of the cylinder is 5 units.
the volume of a cylinder is calculated by first standing it upright on one of the circles, and then the volume is ground area times height.
the area of a circle is pi×r².
so the volume here for us is then
pi×2²×5 units = pi×4×5 = pi×20 = 62.83185307... units
and that makes A the correct answer.

Consider the [tex]n[/tex]-th partial sum of a geometric series with first term [tex]a[/tex] and common ratio [tex]r[/tex] between consecutive terms. Then the sum of the first [tex]n[/tex] terms of this series is
[tex]S = a + ar + ar^2 + \cdots + ar^{n-1}[/tex]
Multiply both sides by [tex]r[/tex], then subtract [tex]rS[/tex] from [tex]S[/tex] and solve for [tex]S[/tex].
[tex]rS = ar + ar^2 + ar^3 + \cdots + ar^n[/tex]
[tex]S - rS = a - ar^n[/tex]
[tex]\implies S = \dfrac{a(1-r^n)}{1-r}[/tex]
In the given series, we have [tex]a=1[/tex] and [tex]r=2[/tex]; then the sum of the series with [tex]n=8[/tex] terms is
[tex]S = \dfrac{1-2^8}{1-2} = 2^8 - 1 = \boxed{255}[/tex]

3. A playground designer wanted to place a fountain so that it was close to both the slide and the swings.
Refer to the coordinate grid shown. Each unit on the grid represents 5 ft.
(a) Find the distance from the fountain to the slide. Show your work.
Answer:
10ft
Step-by-step explanation:
Hi! Thanks for using Brainly! My work and explanation is shown below!
Equation Used to Solve:
5x
Solve:
5(2)=10
The slide is 10ft away from the fountain since each unit equal 5 ft, each increase by 1 on the y-value is 5ft, and each increase by 1 on the x-axis is 5ft, meaning that if the slide is at (-2, 0) and the fountain is at (-2, -2) there was an increase of 10ft total.

Customers at the gym pay a membership fee to join and then a fee for
each class they attend. Here is a graph that represents the situation.
1. What is the slope?
F. What is the y-intercept?
Answer:
Slope = 20
y-intercept = 60
Step-by-step explanation:
Slope formula is given as [tex] m = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
Pick two points on the line and use their coordinates. Let's pick (1, 80) and (2, 100).
Let,
[tex] (1, 80) = (x_1, y_1) [/tex]
[tex] (2, 100) = (x_2, y_2) [/tex]
Plug the values above into the formula for slope:
[tex] m = \frac{100 - 80}{2 - 1} = \frac{20}{1}} = 20 [/tex]
Slope of the graph is 20.
The y-intercept is the point where the line intercepts the y-axis. Thus, y-intercept = 60.

Katie’s cell phone plan includes 400 peak minutes. Last month Katie used 240 peak minutes. This month Katie used 300 peak minutes. What was the percent increase in the number of peak minutes Katie used? HELP ASAP
Answer:
25%
Step-by-step explanation:
So you subtract the number of peak minutes Katie used last month from the number of peak minutes Katie used this month. Divide the difference by the number of peak minutes Katie used last month.

Step-by-step explanation:
The first term of a GP is 7, the ratio is 3. What is the sum of the 7th and 10th term?
Solution: In the given GP, a = 7 and r = 3.
The sum of the 7th and the tenth terms
= T7 +T10 = ar^6 + ar^9 = ar^6[1+r^3]
= 7*3^6[1+3^3]

The first term of geometric series is, a = 363/82
What is Geometric sequence?An sequence has the ratio of every two successive terms is a constant, is called a Geometric sequence.
Give that;
Sum of T₃ and T₇ of geometric series = 3267
And, common ratio(r) = 3
Hence, To find first term (a) we can use formula as;
Tₙ = arⁿ⁻¹
Now, put the value on formula;
T₃ = a(3)³⁻¹
T₃ = (3)²a
And, T₇ = a(3)⁷⁻¹
T₇ = (3)⁶a
Since, T₃ + T₇ = 3267
Hence,
(3)²a + (3)⁶a = 3267
3²(a + 3⁴a) = 3267
(a + 3⁴a) =363
a + 81a = 363
82a = 363
a = 363/82
Thus, The first term of geometric series is, a = 363/82
