What is a Triangle :A triangle is a three-sided polygon, which has three vertices. The three sides are connected with each other end to end at a point, which forms the angles of the triangle. The sum of all three angles of the triangle is equal to 180 degrees.
Based on the given conditions, formulate,
A triangle is 5 units right.
That means, +5
And Triangle is 1 unit up.
That means, +1
Original triangle is located at (5,-4)
So, we can write,
⇒ (5+5 , -4+1)
⇒ (10, -3)
Therefore, the new triangle after the translation is equal to = (10, -3).

The formula for the surface area, S, of a cone is shown below. solve the formula for the length l.
Answer:
l = [tex]\frac{S-\pi r^2}{\pi r}[/tex]
Step-by-step explanation:
S = πr² + πrl ( subtract πr² from both sides )
S - πr² = πrl ( isolate l by dividing both sides by πr )
[tex]\frac{S-\pi r^2}{\pi r}[/tex] = l
Answer:
[tex] l = \dfrac{S - \pi r^2}{\pi r} [/tex]
Step-by-step explanation:
[tex]S = \pi r^2+\pi rl[/tex]

Hope this helps :)
Error:
The error was that I'm the first step where they distributed -4 to the numbers - 3n, + 4g, - 2 wrong. They multiplied with the wrong integer rules.
Real answer - how to solve:
- 4 multiply by - 3n would be + 12n (Negative times Negative equals Positive).
-4 multiply by + 4g would be - 16g (Negative times Positive equals Negative).
- 4 multiply by - 2 would be + 8 (Negative times Negative equals Positive).
So that was the error.

Step-by-step explanation:
Question
You buy a container of cat litter for $11.50 and a bag of cat food for x dollars. The total purchase is $16.80, which includes 5% sales tax. Write and solve an equation to find the cost of the cat food.
The equation is (11.50 + x) * (1 + 5%) = 16.80 and the solution is $4.50
How to write and solve an equation to find the cost of the cat food?The given parameters are
Cat litter = $11.50
Cat food = x
Sales tax = 5%
Total =16.80
The equation is then represented as
(Cat litter + Cat food) * (1 + Sales tax) = Total
So, we have
(11.50 + x) * (1 + 5%) = 16.80
Divide both sides by (1 + 5%)
11.50 + x = 16
Evaluate the like terms
x = 4.50
Hence, the equation is (11.50 + x) * (1 + 5%) = 16.80 and the solution is $4.50

Find the product.
23 x 536
Show your work.
Answer: 12328 is the answer
Step-by-step explanation:
You put the 536 on top and 23 on the bottom and you multiply 3 first to get 1608 then you multiply 2 to get 10720. You add these two numbers and you get 12328 as your answer! :D
The product of 23 multiplied by 536 is 12,328.
We have,
The concept used to find the product of 23 multiplied by 536 is basic multiplication.
Start with the rightmost digit of the bottom number (536), which is 6.
Multiply 6 by the top number (23). We have 6 multiplied by 3, which equals 18.
Write down the rightmost digit of the result (8) under the line.
Carry over the remaining digit, which is 1, to the next column.
Now, multiply the carried-over digit (1) by the top number (23). We have 1 multiplied by 3, which equals 3.
Add the carried-over digit (1) to the result (3), which gives us 4.
Write down the rightmost digit of this new result (4) next to the previous digit (8), giving us 48.
Finally, multiply the leftmost digit of the bottom number (5) by the top number (23). We have 5 multiplied by 3, which equals 15.
Write down this result (15) shifted one place to the left, giving us 150.
Add the two partial products: 48 + 150 = 198.
Therefore,
The product of 23 multiplied by 536 is 198.

Triangle JKL is rotated 180° clockwise about the origin.
A four quadrant coordinate plane is
shown. Triangle J K L is graphed. Point J is
located at three comma six. Point K is
located at six comma two. Point L is
located at one comma two.
What are the coordinates of the vertices of J'K'L'?
A J'(−6, 3), K'(−2, 6), L'(−2, 1)
B J'(6, –3), K'(2, –6), L′(2, −1)
C J'(–3, –6), K'(-6, -2), L'(-1,-2) D J’(-3,6), K’(-6,2), L’(-1,2
Answer:
we conclude that if JKL is rotated 180° clockwise about the origin, what are the new coordinates of point J(-4, 6) will be: J' (4, -6)
Hence, the answer choice (B) is correct.
Step-by-step explanation:
The rule of rotating a point 180° clockwise about the origin states that if we rotate a point P(x, y) 180° clockwise about the origin, it would take a new position with the coordinates P'(-x, y).
In other words, the sign of its x and y coordinates change.
Thus, the rule is:
P(x, y) → P'(-x, -y)
Given the triangle ΔJKL with the coordinates
J(-4, 6)
K(-1, 2)
J(-4, 2)
Thus, according to the rule:
P(x, y) → P'(-x, -y)
The new position of point J (-4, 6) will be J' (4, -6)
The new position of point K (-1, 2) will be K' (1, -2)
The new position of point L (-4, 2) will be L' (4, -2)
Finally, we conclude that if JKL is rotated 180° clockwise about the origin, what are the new coordinates of point J(-4, 6) will be: J' (4, -6)
Hence, the answer choice (B) is correct.
Find the unit rate of each birds speed in kilometers per hour
Therefore, the speed of the bird is 55.44 kilometers per hour.
We know that speed is given by the formula distance travelled divided by the time taken.
Here distance = 46.2 meters and time = 3 seconds.
We are asked to find the speed in terms of kilometers per hour.
So, we need to convert the meters into kilometres and the seconds into hours.
We know that 1 kilometer is equal to 1000 meters.
⇒ 1 meter = (1/1000) kilometer
⇒ 1 meter = 0.001 kilometer
Therefore, 46.2 meters = 46.2 × (0.001) kilometers = 0.0462 kilometers
We know that 1 hour is equal to 3600 seconds.
⇒ 1 second = (1/3600) hours
⇒ 3 seconds = (3/3600) hours
Therefore the speed of the bird is equal to
speed = 0.0462 ÷ (3/3600) kilometers per hour
⇒ speed = 3600 × 0.0462 ÷ 3 kilometers per hour
⇒ speed = 3600 × 0.0154 kilometers per hour
⇒ speed = 55.44 kilometers per hour

Think about the law of supply.it states that as prices rise quantity supplied will rise and as prices fall quantity supplied will fall. Now think about the flat screen TV market over the last 15 years or so the prices have come down significantly but there are many more flat screens TVs produced today than there were 15 years ago. Does this violate the law of supply ?
It does not violate the law of supply.
The law of supply states that the quantity of a good supplied (i.e., the amount owners or producers offer for sale) rises as the market price rises, and falls as the price falls. Conversely, the law of demand says that the quantity of a good demanded falls as the price rises, and vice versa.
we can also say that ,The law of supply says that a higher price will induce producers to supply a higher quantity to the market. Because businesses seek to increase revenue, when they expect to receive a higher price for something, they will produce more of it.
An increase in price almost always leads to an increase in the quantity supplied of that good or service, while a decrease in price will decrease the quantity supplied.
The law of supply is a fundamental principle of economic theory which states that, keeping other factors constant, an increase in price results in an increase in quantity supplied.In other words, there is a direct relationship between price and quantity: quantities respond in the same direction as price changes.
Hence ,It does not violate the law of supply.

We have to find the value from the above given data set which have a relative frequency of 30%.
Relative frequency = (subgroup count / total count) × 100
Here, 20 is the most repeating value. So we can calculate with it.
There are three 20's in the set.
So, subgroup count = 3
Total count = 10

Percent of nurses 5.8% 9.9% 19.9% 29.5% 25.4% 7.8% 1.7%
The age distribution of nurses in Great Britain at the time of Florence Nightingale will be 30 - 39, 40 - 49, etc.
How to illustrate the information?Age distribution, also known as age composition, is the proportion of people in each age group within a given population in population studies. The main reason why age distributions vary between nations is because of variations in fertility rates and trends.
It can be estimated by dividing the populations of those aged 0 to 14, and 65 and older, by those aged 15 to 64. Example: In a town, there are 6,800 people over the age of 65 and 41,650 children under the age of 14.
The percentages of people in a population who are a certain age have a significant impact on how quickly that population grows.
