Answer:
300, percentage increased by 12% (percent) of its value = 336
Step-by-step explanation:
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 number of passengers in 2018 were about

Find the missing angles x and y vertical/adjacent angles
Answer: x = 49 degrees, y = 41 degrees
Step-by-step explanation:
Using supplementary angles, we know that x + y + 90 degrees = 180 degrees.
Using complimentary angles, we know that x + 41 degrees = 90 degrees, and x + y = 90 degrees.
Solving first for x,
x + 41 degrees = 90 degrees
x = 90 - 41 degrees
x = 49 degrees
Solving for y,
x + y = 90
Substituting 49 degrees in for x,
y + 49 degrees = 90 degrees
y = 90 - 49 degrees
y = 41 degrees
Lamar's office recycled a total of 6 kilograms of paper over 3 weeks. how many weeks will it take lamar's office to recycle a total of 24 kilograms of paper? solve using unit rates.
Lamar's office will take 12 weeks to recycle a total of 24 kilograms of paper
Information about the problem:
Kg recycled= 6 kgtime= 3 weeksWeeks= ?Total recycle = 24 KgTo solve this problem, we have to state the equation using the information of the problem:
Calculating the recycle rate of Lamar's office, we get:
Rate = Kg recycled / time
Rate = 6 kg/3 weeks
Rate = 2 kg/week
Calculating how many weeks Lamar's office will take to recycle 24 kilograms:
Weeks = Total recycle/ rate
Weeks = 24 kg / 2kg/week
Weeks = 12 weeks

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.

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.

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:
1000 x 1.35261 = $1,352.61.1000 x 1.35 = $1,350.Hence 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 maximum value for y in the following function?
Answer:
D. 8
Step-by-step explanation:
well, let's look at the different parts of the functional expression :
the maximum of 5 is 5, of course.
the maximum of 3 is 3.
the maximum of sin(2x) is the maximum of any sine = 1.
sin(2x) only changes the frequency of the sine wave (the max and min values appear twice as often than for sin(x)), but does not have an impact on the amplitude, which defines the max. and min. values.
sin(2x) is NOT the same as 2×sin(x).
sin(2x) still "waves" between +1 and -1.
so, the total maximum is
5 × 1 + 3 = 8
Bob told Margaret that he ate half if the amount of cookies that Jeff ate. Margaret does not know how many cookies Jeff ate.
If bob actually ate one more than half of the amount Jeff ate, write an expression that represents the amount of cookies bob ate
The expression that represents the amount of cookies Bob ate is 1 + 0.5x.
How to illustrate the expression?From the information, Bob told Margaret that he ate half if the amount of cookies that Jeff ate. Bob actually ate one more than half of the amount Jeff ate.
Let the amount that Jeff are be represented as x.
Since Bob actually ate one more than half of the amount Jeff ate, this will be:

(−20)÷4=−5
What does the number sentence mean?
1. The total drop in temperature, −20∘F, divided by 4 hours equals −5∘F per hour. The temperature dropped 5∘F each hour.
2. The total number of drops, 20, divided by 4 hours equals 5 times per hour. The temperature dropped 5 times per hour.
3. The total drop in temperature, −20∘F, divided by 4∘F in the first hour, equals −5 drops. The temperature dropped 5 times.
4. The total number of hours, 20, divided by 4∘F equals 5 hours. The temperature dropped once every 5 hours.
The total drop in temperature, −20∘F, divided by 4 hours equals −5∘F per hour. The temperature dropped 5∘F each hour. (option 1)
What does the sentence mean?Division is the process of grouping a number into equal parts using another number. The sign used to denote division is ÷. Division is one of the basic mathematical operation.
If the total drop in temperature over 4 hours is −20∘F, in order to determine the temperature drop each hour, divide −20∘F by 4.
