Vernon put 16 liters of gas in his tank. 21 miles per gallons of gas are consumed each mile that is driven.
Given that,
Vernon put 16 liters of gas in his tank.
The table depicts the linear relationship between the mileage driven and the amount of gas in his tank.
We have to find how many gallons of gas are consumed each mile that is driven.
From the table we can say
The total Distance is 336
The total gallons of gas is 16
Rate= Total distance/Total gallons
Rate=336/16
Rate=21 miles per gallons
Therefore, 21 miles per gallons of gas are consumed each mile that is driven.

The value of the variable x is 5 and the lengths of PL and LQ are 9 and 48, respectively.
How to find the value of a variable and the length of the line segments behind that variable
In this problem we find a line segment generated by points P and Q and in which a point L divides the line segment PQ in two sections: PL and LQ. In accordance with the statement, we have the following equations describing the geometric system:
PQ = PL + LQ
PQ = PL + LQ
57 = (2 · x - 1) + (9 · x + 3)
Now we proceed to clear the variable x with the resulting equation:
57 = 11 · x + 2
55 = 11 · x
x = 5
And finally we find the length of each line segment:
PL = 2 · 5 - 1
PL = 9
LQ = 9 · 5 + 3
LQ = 48
The value of the variable x is 5 and the lengths of PL and LQ are 9 and 48, respectively.

The distance from Tacoma to Seattle is estimated as 25 miles.
What is distance?Distance is defined as an object's total movement without regard for direction. Distance can be defined as the amount of ground an object had also covered regardless of its beginning or ending point.
Distance is the total length of the path in between two points.Distance is a scalar quantity because it is determined solely by magnitude and not by direction.Only positive values can be assigned to distance.Now, as per the given question;
The following are the distances between cities:
120 miles from Portland to Tacoma
145 miles from Portland to Seattle
120+x = 145
x = 145 - 120

17h - 7 = 10h - 2 + 7h
Our initial equation:
17h - 7 = 10h - 2 + 7h
I want to get variables ("h") on one side, and numbers on the other, hence I will add 2 to both sides to shift numbers to the left side.
17h - 5 = 10h + 7h
Now I want to simplify the "h" on the right side.
17h - 5 = 17h
Now I will move the variable from the left to the right.
-5 = 0
17h - 17h is zero, think of h being equal to 1 if you don't get it.
-5 = 0 is a false inequality, there are no solutions.

State the interval for which the following function is positive and its intercepts.
Answer:
see explanation
Step-by-step explanation:
the function is positive for values of y above the x- axis
the line goes on forever on the left side and terminates at x = 15 on the right side.
the interval where the function is positive is (- ∞, 15 ]
the x- intercept is where the line crosses the x- axis ( y = 0 )
x- intercept = 15
the y- intercept is where the line crosses the y- axis (x = 0 )
y- intercept = 3
331 students went on a field trip. Six
buses were filled and 7 students
traveled in cars. How many students
were in each bus?
The number of students in each bus are 54 students .
Given that, 331 students went on a field trip. Six buses were filled and 7 students traveled in cars.
Now you may get that only 7 students out of 331 are travelled in cars whereas others travelled by bus.
number of total students travelled by bus are 331-7 = 324 students
Therefore 324 students travelled in 6 buses.
Number of students travelled in each bus = 324/6 = 54 students.
Therefore number of students travelled in each bus is 54 students .
verification:
number of buses = 6
number of students in each bus = 54
Therefore total number of students in 6 buses = 6*54 = 324 students.

mary robertson sells tires at a large car service center she earns 10 commission on the first $1000 15 on the next $2000 and 20 on sales of more than $3000 last
Her total commission was $560.
As 10% of the first $1,000, 15% of the next $2,000, and 20% of sales beyond $3,000 are commissions that she receives. She sold $3,400 worth of tires last week.
What does "total commission" mean?
The commission serves as a benefit or an inducement for the worker to close agreements so that the business can increase revenue and profits. The total commission is calculated by multiplying the total sales by the commission percentage.
After dividing the outcome by 100, multiply the sale price by the commission percentage. Perform the subsequent calculation: Each blue gadget costs $70. The salesman receives a 14% commission on each sale, or $9.80.
The percentage or fixed payment connected to a specific number of sales is referred to as a "commission rate." A commission, for instance, can be $30 or 6% of sales.
It is therefore $560.

Answer:
d = 510 km
Step-by-step explanation:
She travelled the final 4 hours at a constant speed of 60 km/h.
distance = speed × time
distance = 60 km/h × 4 hours
distance = 240 km for the last 4 hours
She already had travelled 270 km in the first 3 hours.
d = total distance = 270 km + 240 km = 510 km
Answer: d = 510 km
From 2018 to 2010, the total number of passengers passing through Changi Airport increased by 4% In 2019, the total number was 68 280 000. Calculate the number of passengers passing through Changi Airport in 2018.
Leave your answer correct to the nearest whole number.
Step-by-step explanation:
I guess this means from 2018 to 2019 (and not to 2010).
so, compared to 2018 the numbers of 2019 were 104% (100% of 2018 plus 4% increase).
104% = 68,280,000
100% = 104%/1.04 = 68,280,000/1.04 =
= 65,653,846.15 ≈ 65,653,846

The decay rate of a certain new cell phone is 0.333
For given question,
The average lifetime of a certain new cell phone is three years.
The manufacturer will replace any cell phone failing within two years of the date of purchase.
Also, the lifetime of these cell phones is known to follow an exponential distribution.
We need to find the decay rate.
We know that an exponential decay is the process of reducing an amount by a consistent percentage rate over a period of time.
since the average lifetime of a certain new cell phone is three years, the decay rate would be 1/3 = 0.333
Therefore, the decay rate of a certain new cell phone is 0.333

No, by rounding the conversion ratio, the Ruiz family will not be getting the most accurate answer. Using the more accurate conversion ratio will give an answer with more than 2 decimal places so the answer can accurately be rounded after the conversion.
Using proportions, it is found that the Ruiz family is not getting the most accurate ratio and are losing money, thus the rounding should be realized after the conversion.
What is the missing information?The Ruiz family is exchanging Euros for USD dollars, considering the following currency rate:
1 euro = 1.35261 USD.
Considering that the amounts in USD are rounded to the nearest hundredth, the use the following rule
1 euro - 1.35 USD.
It asks if the Ruiz family will be getting the most accurate answer.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
For this problem, we suppose a 1000 euros amount, them:
