the sum of three consecutive even integers is less than or equal to 42. find the largest set of these numbers
Answer:
13, 14, 15
Step-by-step explanation:
13 + 14 + 15 = 42
Better explanation:
n + (n+1) + (n+2) = 42
42 - 2 - 1 = 39
n + n + n = 39
3n = 39 divide by 3 to isolate n
n = 13
So it starts with 13 and goes up from there.

A new car sales person, sold an average of $46,975 per day for the first two days she worked. The next one days she worked, she sold an average of $45,765. How much did she sell on average per day over the entire time she worked?
Answer:
$46,571.67
Step-by-step explanation:
if your description is right and complete, she sold cars on the first 2 days as average for $46975.
and on the third day for $45765
to calculate the total average we need to know the total amount of sales and then divide it by the observation period length (3 days).
how do we get the total sales ?
we know the average of the first 2 days. we don't need to find the exact value for every day, but we know the exact value for these first 2 days : 2×46975 = $93950
as the average of these 2 days = (day1 + day2)/2
46975 = (day1 + day2)/2
day1 + day2 = 2×46975 = 93950
it is not important what two (day) numbers created 93950. we know that this was the total sum of the first two days. and that is enough.
so, we have in total
$93950 on the first 2 days
$45765 in the third day
-------------
$139715 for all 3 days
the average per day is then
139715 / 3 = $46,571.67

Answer:
r = 6
Step-by-step explanation:
– 36 – 4r = -2(-6 + 6r)

r = 6
Answer:
r = 6
Step-by-step explanation:
– 36 – 4r = -2(-6 + 6r)

Write 0.002349 in scientific notation.
Hi! I'm happy to help!
To solve this, we first need to know what scientific notation is. Scientific notation is a way a number is written. You write it using a number ranging from 1 to <10. Then, you multiply this number by [tex]10^{x}[/tex].
In order to make this number reasonable for scientific notation, you have to move the decimal a certain amount of places. In this case you move it 3 places to the right to make your number 2.349. Since we moved it 3 places to the right our x will be -3. (If we'd moved it 3 places to the left, our x would be positive 3.)
So now, we insert our numbers:
2.349·[tex]10^{-3}[/tex]
You write 0.002349 like 2.349·[tex]10^{-3}[/tex], when it is in scientific notation.
I hope this was helpful, keep learning! :D

Tap A takes 6 minutes to fill a tank and tap b takes 9 minutes to fill the same tank. Pipe C can empty the tank in 15 minutes. How long will it take to fill the tank if the pipe is in use when both taps are turned on
Answer: approximately 4.7368 minutes
This decimal value is the result of computing 90/19
=====================================================
Explanation:
Let's find the LCM of 6, 9 and 15. First, list out the prime factorization of each value.
6 = 2*39 = 3*315 = 3*5The unique prime factors are 2, 3, and 5. We have 2 show up at most once, 3 show up at most twice, and 5 show up at most once. The LCM is 2^1*3^2*5^1 = 2*9*5 = 18*5 = 90.
We'll use this LCM value to set up an example below.
---------------
Consider the tank to be 90 gallons. If we only use tap A, keep tap B closed, and don't open pipe C, then tap A fills the tank at a rate of 90/6 = 15 gallons per minute since it needs 6 minutes to completely fill the tank.
If we have tap B do all the work (keep tap A and pipe C closed), then the rate is 90/9 = 10 gallons per minute for this tap.
Keeping pipe C closed, the two taps A and B work together to have a combined rate of 15+10 = 25 gallons per minute.
Now we consider pipe C being opened. This drains the tank and can do so in 15 minutes (assume the taps A and B aren't open). If we're dealing with a full 90 gallon tank, then its rate is 90/15 = 6 gallons per minute.
The net rate is 25-6 = 19 gallons per minute. We can think of it as a tug of war where the taps A and B ultimately win out despite the fact that pipe C is draining the water. The two taps fill the tank faster than the pipe can drain the tank.
In other words, the tank ultimately gets filled up rather than drained out over the long run. That net speed is at 19 gallons per minute.
The amount of time needed is approximately 90/19 = 4.7368 minutes.
Side note: you can start with any size tank. It doesn't have to be 90 gallons. I picked on this value because it works cleanly with the original given numbers 6, 9 and 15.
Answer:
[tex]x=\frac{90}{19}[/tex] = 4.73 minutes
[tex]\frac{1}{6}x +\frac{1}{9}x - \frac{1}{15} x = 1[/tex]
[tex]\frac{135}{810}x +\frac{90 }{810}x - \frac{54}{810} x = 1[/tex]
[tex]\frac{171}{810}x = 1[/tex]
x = 4.73 minutes

Step-by-step explanation:
expression =4a-|3b+2c|
subtitute all values in the expression:
=4(-2) -|3(-3)+2(2)|
=-8-|-9+4|
=-8-|-5|
=-8-(5)
=-8-5
=-13
Note:if you need to ask any question please let me know.
The value of the expression from the variables is -13
How to evaluate the expression from the variablesFrom the question, we have the following parameters that can be used in our computation:
4a - |3b + 2cl
Also, we have
a = - 2, b = -3, c = 2, x = 2.1, y = 3, and z = - 4.2.
substitute the known values in the above equation, so, we have the following representation
4a - |3b + 2cl = 4 * -2 - |3 * -3 + 2 * 2|
Evaluate
4a - |3b + 2cl = -13
Hence, the expression from the variables is -13

Including a 5% sales tax, an inn charges $172.20 per night. Find the inn's nightly cost before tax is added.
The cost of the room before the tax is X.
To get the total cost they multiply the cost of the room x by 1 + sales tax rate.
Total cost would be x(1.05)
To find x divide total cost by 1.05:
Cost of room before tax: 172.20/1.05

In 2015, 120000 people voted. The number of viewers who voted in 2015 was 20% more than those in 2014. Calculate the numbers of viewers who voted in 2014
Answer:
Given;
120,000 people voted in 2015.
In 2015, 20% more people voted than 2014.
Therefore:
How many more people voted in 2015 = 20% of 120,000
= 24,000
Total number of people voted in 2014 = 120,000 - 24,000
= 96,000
Ans) 96,000 people voted in 2014.

Which of the following is in the solution set of the inequality -3 > -3t+ 6?
A. -1/3
B. 1/3
1مرايا C. 4
D. -4
Answer: C) 4
==========================================================
Explanation:
Let's isolate t
-3 > -3t + 6
-3+3t > 6
3t > 6+3
3t > 9
t > 9/3
t > 3
This means any value can replace t such that it's larger than 3.
Something like t = 1/3 = 0.33 won't work since it's not larger than 3.
But something like t = 4 would work because it makes t > 3 true.
That's why choice C is the final answer.

Jamil buys a video game for 20% off the original price. He pays $36, excluding sales tax. One week later, he sees an advertisement for $10 off the original price. This is the new sales price. Complete the sentence to explain whether Jamil paid more or less than the new sale price, excluding sales tax.
The new price offers price is less than the offer of 20% discount.
Given that,
Jamil buys a video game for 20% off the original price. He pays $36, excluding sales tax. One week later, he sees an advertisement for $10 off the original price. This is the new sales price.
The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
Here,
percentage of the price paid = 1 - 0.2 = 0.8
Let the original price be x,
According to the question,
36 = 0.8 (x)
x = 36/0.8
x = $45
Since the original price is $45,
As of the new price, the price is $10 so the price becomes $35 which is less than a 20% discount.
Thus, the new price offers price is less than the offer of 20% discount.
