Find the quotient. 22x2y2 ÷ 11x2y2
Quotient = 2
Solution:
Given expression is [tex]22x^2y^2\div11x^2y^2[/tex].
To find the quotient.
[tex]22x^2y^2\div11x^2y^2=\frac{22x^2y^2}{11x^2y^2}[/tex]
In numerator 22 can be written as 2 × 11.
[tex]\frac{22x^2y^2}{11x^2y^2}=\frac{2\times11x^2y^2}{11x^2y^2}[/tex]
Take common term out in the numerator and denominator.
[tex]\frac{22x^2y^2}{11x^2y^2}=\frac{(11x^2y^2)(2)}{11x^2y^2}[/tex]
Common terms in the numerator and denominator will be cancelled.
[tex]\frac{22x^2y^2}{11x^2y^2}=2[/tex]
Hence the quotient is 2.

The function y = – 3 is graphed only over the domain of {x | –8 < x < 8}. What is the range of the graph?
The range of the function y = -3, graphed over the domain {x | -8 < x < 8}, is a singular value, which is y = -3.
Explanation:The question asks for the range of the function y = -3 which is graphed only over the domain {x | -8 < x < 8}. This function is a horizontal line, which means that for any value of x within the domain, the value of y will always be -3.
Therefore, the range of this function is simply the single value y = -3, because no matter what x-value we have (as long as it's between -8 and 8), the y-value remains constant at -3.

How many liters of water must be added to 15 liters of 40 % sugar syrup to obtain 30 % sugar syrup?
Answer:
5 liters of water.
Step-by-step explanation:
Let [tex]y[/tex] be the liters of water that must be added to 15 liters of 40% sugar syrup.
Initially, we have [tex]0.4(15)=6[/tex] liters of sugar syrup, and since adding water does not add any new syrup, the amount of sugar syrup must be the same after the water has been added. After the water has been added, 30% of the solution is sugar syrup, or
[tex]Sugar\:syrup =0.3(15+y)[/tex]
And since this must equal the amount of syrup we had before:
[tex]0.3(15+y)=0.4(15)[/tex]
[tex]4.5+0.3y=6[/tex]
[tex]0.3y=1.5[/tex]
[tex]\boxed{y=5}[/tex]
Thus, 5 liters of water must be added to obtain 30% sugar syrup.
Answer:
5 liters of water

How to you use a unit rate to solve a rate problem for any number of units?
Answer:
Here, we have used the unit rate i.e. speed of 30 mph to get the distance traveled in 5 number of units i.e. 5 hours.
Step-by-step explanation:
We are asked the way to use a unit rate to solve a rate problem for any number of units.
Let, us assume that a car is moving at a unit rate of 30 miles per hour. And we have to calculate the distance it travels in 5 units of time i.e. 5 hours.
Now, the distance traveled in 5 hours will be given by 30 × 5 = 150 miles.
Since [tex]\textrm {Speed} = \frac{\textrm {Distance}}{\textrm {Time}}[/tex] and here, speed is 30 miles per hour and the time is 5 hours. (Answer)
You estimate that your friend is 50 inches tall. That actual height of your friend is 54 inches. Find the percent error.
To find the percent error, calculate the absolute difference between the estimated height and the actual height, and divide it by the actual height. Finally, multiply the result by 100 to get the percentage.
Explanation:To find the percent error, we need to calculate the absolute difference between the estimated height and the actual height, and then divide it by the actual height.
Finally, we multiply the result by 100 to get the percentage.
Step 1: Determine the difference between estimated and actual height.
Difference = Actual height - Estimated height
Difference = 54 inches - 50 inches
Difference = 4 inches
Step 2: Calculate the absolute value of the difference.
Absolute value of the difference = |4 inches|
Absolute value of the difference = 4 inches
Step 3: Divide the absolute difference by the actual height and multiply by 100% to get the percent error.
Percent Error = (Absolute difference / Actual height) × 100%
Percent Error = (4 inches / 54 inches) × 100%
Percent Error ≈ 7.41%
Therefore, the percent error in your estimation of your friend's height is approximately 7.41%.

trigonometry help (angles of evaluation and depression)
Answer:
240.3
Step-by-step explanation:
Remember SohCahToa for the trig. ratios. You always divide two sides.
'o' is opposite side. 'a' is adjacent side. 'h' is hypotenuse side.
Using alternating angles you can find the angle I marked blue (see diagram below). Because the 31° is parallel to the bottom side of the triangle, you can use alternating angles (Z pattern), where both 'insides' of the Z have the same measure.
The blue angle will be our angle of reference (angle we are talking about) represented by this symbol θ.
Since we need to find 'y', the opposite side, and we know 400ft is the adjacent side, use the tangent ratio.
tanθ = opposite / adjacent
tan31° = y / 400ft Substitute what you know.
y = (400ft)tan31° Isolate 'y'. Multiply 400ft and tan31°.
y = 240.344......ft Exact answer on calculator
y ≈ 240.3ft Answer rounded to nearest tenth
The nearest tenth is the first decimal. Since the second decimal is '4 or less', you round down, keeping the digit of the first decimal the same.

This year's Super Bowl will be the 54th. There have been 53 Super Bowls and
the NFC has won 3 more Super Bowls then the AFC. How many games did each
conference win?
Answer:
Therefore NFC won 28 games and AFC won 25 games.
Step-by-step explanation:
i) let the number of Super Bowls won by NFC be x
ii) let number of Super Bowls won by AFC be y
iii) therefore it is given that x + y = 53
iv) and also it is given that x = y + 3
v) substituting the equation in iv) into the equation in iii) we get
(y +3) + y = 53 ⇒ 2y = 50 therefore y = 25.
vi) substituting the value of y from v) into the equation iv) we get
x = 25 + 3 = 28.
Therefore NFC won 28 games and AFC won 25 games.
To solve this mathematics problem, we formulate an equation based on the information that total Super Bowls were 53 and NFC won 3 more than AFC. By solving the equation, we find that NFC won 28 games and AFC won 25 games.
Explanation:To solve this problem, let's start with the total number of games, which is 53. If the NFC has won 3 more Super Bowls than the AFC, that means the number of games won by both conferences adds up to 53. Let's denote the number of games won by the AFC as 'x'. So, the equation will be:
x + (x + 3) = 53By combining like terms, we get:
2x + 3 = 53Subtracting 3 from both sides, we have:
2x = 50Finally, when we divide by 2, we solve for x:
x = 25This means that the AFC has won 25 games, and the NFC, having won 3 more, has won 28 games.

Answer:
Step-by-step explanation:
If the baby repeats this sleep pattern until she is awakened at 6 a.m., what ... We have 10 hours between 8PM and 6AM = 10 * 60 = 600 minutes ... Awake 12:15 - 12:30 ... There are 4 periods of 2 hour sleep and 1 period of 1 hour sleep = 4*2(60) + 1(60) ... So 540/600 = 54/60 = 9/10 = 90% of the time asleep.
Answer:
87.5%
Step-by-step explanation:
I am not sure how to set this up....so I am just gonna try to figure this a different way....without any formula
8 p.m - 10 pm.......awake for 15 minutes
10 pm - 12 am......awake 15 minutes
12 am - 2 am.......awake 15 minutes
2 am to 4 am.....awake 15 minutes
4 am to 6 am....awake 15 minutes
so from 8 pm to 6 am....that is a total of 10 hrs.....and in those 10 hrs, the baby was awake 5(15) = 75 minutes.....change 10 hrs to minutes.....1 hr = 60 min...so 10 hrs = (10 * 60) = 600 minutes
so in 600 minutes, the baby was awake 75 minutes.....that means the baby was asleep (600 - 75) = 525 minutes
525/600 = 0.875 = 87.5% <=== baby was asleep
or maybe this way....for every 2 hrs, the baby was awake 15 minutes....means the baby was asleep (120 - 15) = 105 minutes.
2 / 105 = 10 / x
2x = 1050
x = 1050/2
x = 525 minutes.....so the baby was asleep 525 minutes out of 600 minutes.
525/600 = 0.875 = 87.5%

Answer:
The total discounted price is 34.93
Step-by-step explanation:
The items in the cart are:
Shampoo for $6.35Conditioner for $6.35Granola bars for $12.50Dish soap for $13.40 Toothpaste for $2.50Total cart = $ 41.10
Discount = 41.10 * 0.15 = $ 6.17
Discounted total price = 41.10 - 6.17
Discounted total price = 34.93
Answer:
34.94.
Step-by-step explanation:
First we must find the total price of all the items: =$6.35+$6.35+$12.50+$13.40+$2.50=$41.10.
Next, we can calculate the discount: =(15/100)×$41.10=$6.165.
Therefore, our discounted price is $41.10−$6.165=$34.935≈$34.94.
