Answer:
Step-by-step explanation:
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.
A vehicle hire firm charges $20 as a flat fee for renting a vehicle plus $2 per mile. If the total cost of hiring a vehicle on one occasion is 170, how many miles were driven
Answer:
85
Step-by-step explanation:
Because 170 divided by 2.
The number of miles is 75 miles if the vehicle hire firm charges $20 as a flat fee for renting a vehicle plus $2 per mile.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
A vehicle hire firm charges $20 as a flat fee for renting a vehicle plus $2 per mile.
Let x be the total number of miles:
From the question:
y be the total cost of hiring
y = 20 + 2x
y = 170
170 = 20 + 2x
150 = 2x
x = 150/2
x = 75 miles
Thus, the number of miles is 75 miles if the vehicle hire firm charges $20 as a flat fee for renting a vehicle plus $2 per mile.

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.
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. Then multiply by 100 to find the percent increase. Katie used 25% more peak minutes this month than last month.

here a subtraction problem that has been solved incorrectly 21-9=11 what is the correct way
what is the slope of a line parallel 18x+15y=90
Answer:
-6/5
Step-by-step explanation:
Get y by itself to get the slope. So 18x+15y=90. Move 18x to the other side of the equation. Now you have 15y=-18x+90. Divide both sides by 15 to get y by itself. Now it's y= -18/15x + 6. Reduce -18/15 to the simplest fraction. You have y= -6/5x+6. Any number can replace the 6 in the equation to give you a parallel line...it's the slope that makes it parallel, not the y intercept. So y= -6/5x+10 or y=- -6/5x-1 would satisfy your parallel slope equation.
Answer:
[tex]\displaystyle -1\frac{1}{5}[/tex]
Step-by-step explanation:
[tex]\displaystyle 18x + 15y = 90 \hookrightarrow \frac{15y}{15} = \frac{-18x + 90}{15} \\ \\ \boxed{y = -1\frac{1}{5}x + 6}[/tex]
Parallel equations have SIMILAR RATE OF CHANGES [SLOPES], so −1⅕ remains as is.

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.
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.

At a nearby frozen yogurt shop, the mean cost of a pint of frozen yogurt is $1.50
with a standard deviation of $0.10.
Assuming the data is normally distributed, approximately what percent of
customers are willing to pay between $1.30 and $1.70 for a pint of frozen
yogurt?
T
9514 1404 393
Answer:
95%
Step-by-step explanation:
The given limits differ from the mean by ...
1.30 -1.50 = -0.20
1.70 -1.50 = 0.20
These values are 2 × the standard deviation of 0.10. The 68-95-99.7 rule tells you that 95% of the population lies within 2 standard deviations of the mean.
For this question, that means 95% of customers are willing to pay between $1.30 and $1.70.

My father’s monthly salary is twice what my mother makes in a month. Their combined salary is P27,000
Please help !
Step-by-step explanation:
mother salary: x
father salary:2x
total salary =27000
therefore 3x=27000
so x=900 (divided by 3)
therefore mother salary = 900
father salary=2multiplied by 900=1800
Answer:
Father's monthly salary is P18,000
Mother's monthly salary is P9,000
Step-by-step explanation:
The problem above can be solved by using "algebraic expressions."
Let x be the father's monthly salary
Let y be mother's monthly salary
Formula: x + y = P27,000
If father's monthly salary is twice than what mother makes, then: x = 2y, which means,
2y (father's salary) + y (mother's salary) = P27,000
First step: 2y + y = P27,000
Second step: 3y = P27,000
Third step: y = [tex]\frac{P27,000}{3}[/tex]
Fourth step: y = P9,000
So, mother's salary is P9,000. This means we can get father's salary:
2y = 2 × P9,000 = P18,000 (this is the value of x)
So, father's salary is P18,000.
If we combine both of their salaries, the product is P27,000.
x + y = P27,000
P18,000 + P9,000 = P27,000
So, this explains the answer.

paraboloid: v = ∫[0,4]πz dz = 8π cone:

hyperboloid: v = ∫[1,5]π(z^2-1) dz = 112/3 π

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
