The territory of a small town can be modeled by a rectangle with an area of 45 square miles. If the town has a population of 14,850, then what is its population density?
Answer:
330 people per square mile
Step-by-step explanation:
Here, we want to find the population density of the town
To find this, we have to divide the population by the area
That will be ;
14,850/ 45 = =330 people per square mile
3. Askating rink charges a group fate of $9 plus a fee to rent each pair of skates. A family rents 7 pairs of skates and pays a total of $30.
Each skate rental is $______
Answer:
$3Step-by-step explanation:
Let the rental is x
The total is, the equation:
7x + 9 = 307x = 21x = 3Each skate rental is $3
7x+9=30
7x=30-9
7x=21
x=21÷7
x=3
Does anyone know these answers??
The angles of a triangle always add up to 180°.
By simply adding the angles and checking the total, you can tell if they make a triangle or not.
Using this property, 5 won't make a triangle, 6 will.

The mean of the dataset is 3.55
How to determine the mean?The dataset is given as:
0 | 3, 8
1 | 0, 1, 4, 7,
2 | 2, 4, 5
3 | 5 0
Remove the stems

Answer:
x = 3.6
Step-by-step explanation:
Since, ABCD ~ EFGH
Therefore, all interior angles of both the quadrilaterals will be equal and the corresponding sides of both quadrilaterals will be proportional.
[tex]\frac{AD}{EH}=\frac{AB}{EF}[/tex]
[tex]\frac{x}{2.4}=\frac{3}{2}[/tex]
x = [tex]\frac{3\times 2.4}{2}[/tex]
x = 3.6

Answer: 4
You would set this up like so:
125 ≤ 29.50 + 19.50x
Subtract 29.50 from both sides.
You should be left with 95.50 ≤ 19.50x
From here, you wanna divide both sides by 19.50 (we do this to isolate the x)
You would get 4.89.
Since Tamesha can't buy half a shirt, you don't wanna round up. So, the answer should be 4.
Step-by-step explanation:
Trust Milky. Milky smart!
Answer:
she can buy 4 shirts
Step-by-step explanation:
maximum that she can spend = $125
dress = $29.50
shirt = $19.50
first, take 29.50 and subtract it from 125
⇒ 125 - 29.50 = $95.50 remaining
then take 95.50 and it divide it by 19.50 to determine how many shirts she can buy
⇒ [tex]\frac{95.50}{19.50}[/tex] = 4.897
⇒ 4 shirts
to solve:
take 4 shirts and multiply it by 19.50
⇒ 4 x 19.50 = $78
then take the product and add 29.50
⇒ 78 + 29.50 = 107.50
take the maximum money and subtract 107.50 from it
⇒ 125 - 107.50 = 17.5
Tamesha would have $17.50 remaining.
An online clothing company sells custom sweatshirts. The company charges $4.99 for shipping plus $20 for each sweatshirt. Write a linear function rule that models the total cost y (in dollars) for any number of sweatshirts x.
Answer:
20x+4.99=y
Step-by-step explanation:
Each sweatshirt cost $20, but we don't know how many sweatshirts someone will buy so we use X, representing the amount of sweatshirts. There is a shipping charge of $4.99, so we have to add that to the cost of the sweatshirts. 20x+4.99. Y is the total cost.

What is the Pythagorean theorem?In the Pythagorean theorem, the sum of the squares of the sides of a right-angled triangle is equal to the square of the longest side i.e, the hypotenuse of the triangle.
z² = x² + y²
The given triangle is a right-angled triangle. This means that we can use the Pythagorean theorem.
∴ y² + 12² = 13²
⇒ y² + 144 = 169
⇒ y² = 169-144
⇒ y² = 25
⇒ y = 5
Therefore, we have solved for the value of y and found that y = 5. The correct answer is option C.

When Shawn cleaned his room he found that the ratio of clean clothes to dirty clothes was 3 to 5 if 46 articles of clothing were discovered how many were clean
Answer:
17.25
Step-by-step explanation:
Ratio of clean clothes to dirty clothes = 3 : 5
Clean clothes = 3
Dirty clothes = 5
Total ratio = 3 + 5 = 8
Total clothing article = 46
how many were clean
Number of clean clothes = ratio of clean clothes / total ratio × total clothing article
= 3/8 × 46
= 0.375 × 46
= 17.25

16a²-121b²
Answer:
(4a - 11b)(4a + 11b)
Step-by-step explanation:
16a² - 121b² ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b) , then
16a² - 121b²
= (4a)² - (11b)²
= (4a - 11b)(4a + 11b)
Answer:
Step-by-step explanation:
Rule: (a^2-b^2)=(a-b)(a+b) (‘difference of squares’)
16a^2-121b^2
(4a-11b)(4a+11b)
Since 1900, the Audubon Society has conducted an annual Christmas bird count, documenting the number of birds of each species seen in locations across the country. In the 2011 Christmas bird count, there were 3,813 red-tailed hawks seen and counted in Texas. In the 2012 count, there were 4,511 red-tailed hawks counted in Texas. Calculate the growth rate by dividing the difference in the numbers seen in the two years by the number seen in 2011. Then use this value to calculate the estimated population of red-tailed hawks in Texas in 2022, if the growth rate remains constant.
Answer:
The answer is 23,610
Step-by-step explanation
First: 4,511-3,813= 698
Second: 698/3,813 = 0.18
Third: 4,511(1+0.18)^10 {could be put on a ti-84 calculator}
Answer: About 23,610 ( This is an estimate as the answer is an decimal)
