The length of the hypotenuse of the triangle is √61 ft
How to determine the length of the hypotenuse?From the question, we have the following parameters that can be used in our computation:
Smaller sides = 6ft and 5 ft
Hypotenuse = c
The hypotenuse of a triangle is calculated using the following Pythagoras theorem
Hypotenuse^2 = Opposite^2 + Adjacent^2
Where Opposite and Adjacent are 6 and 5
So, we have
c^2 = 5^2 + 6^2
Evaluate
c^2 = 61
Take the square roots
c = √61
Hence, the hypotenuse is √61 ft

Is the comparison true
8•1/11>8
Comparison of the given inequality ( 8.1 /11 ) > 8 is not true.
As given in the question,
Given inequality is :
( 8.1 /11 )> 8
Simplify the given inequality ( 8.1 /11 ) > 8 to check the comparison is true or not.
(8.1 /11)> 8
Multiply both the sides of the given inequality by 11 we get,
( 8.1/11 ) × 11 > 8× 11
⇒ (8 .1) × ( 11/ 11) >88
(8.1 ) × 1 > 88
⇒ ( 8. 1) > 88
For the above inequality, it is not possible as 8 .1 is smaller than 88.
Therefore, comparison of the given inequality ( 8.1 /11 ) > 8 is not true.

Write the correct equation for the following statement and then solve for the given number of
miles.
You decide to rent a limo for prom. The rate is $200 plus $5 per mile
traveled. Write an equation to calculate your total cost (c) at the end of
the evening for a given number of miles (m).
If you travel 45 miles what will be your total bill at the end
of the evening?
Answer:
$425
Step-by-step explanation:
You want the cost of a 45 mile trip in a limo that costs $200 plus $5 per mile.
Mileage costThe cost of each mile is $5, so the cost of 45 of them will be ...
45 × $5 = $225
Total costThere is a one-time charge of $200 added to the mileage charge, so the total cost will be ...
total bill = $200 + mileage bill
total bill = $200 +225 = $425
The total bill will be $425.

Step-by-step explanation:
A company sells sneakers and has a revenue that can be represented by the function R(s) = 90s – s2, where s represents the number of pairs of sneakers sold. The sneaker company has a fixed cost of $1,500, and each pair of sneakers costs $30 to manufacture. Which of the following functions represents the profit P(s) of the sneaker company?
P(s) = – s2 + 120s + 1,500
P(s) = – s2 + 60s + 1,500
P(s) = – s2 + 120s – 1,500
P(s) = – s2 + 60s – 1,500
The function that can represent the profit P(s) of the sneaker company is D. P(s) = – s2 + 60s – 1,500.
What is a function?Mathematically, a function shows a set of inputs that produce one output.
Functions have the domain (independent variable) and the codomain or range (dependent variable).
The domain is always the set of input values, while the range is the output value of the function.
Revenue function R(s) = 90s – s2
Fixed cost = $1,500
Variable cost per unit = $30
Profit = Revenue - Variable and Fixed Costs
Profit function P(s) = 90s – s2 - 30s - 1,500
= 60s - s2 - 1,500
or -s2 + 60s - 1,500
Thus, the correct profit function is Option D.

Answer:
[tex]g(x)=2\cos \frac{2x}{3}[/tex]Explanation:
A cosine function is generally given as;
[tex]\begin{gathered} y=a\cos (b) \\ \text{where Amplitude }=|a| \\ \text{ Period }=\frac{2\pi}{|b|} \end{gathered}[/tex]Given the below function;
[tex]f(x)=\cos x[/tex]If we compare both functions, we'll see that a = 1 and b = 1.
If we need another function with double the amplitude, then the value of a in that function will be (a = 2 x 1 = 2).

[tex]\frac{\text{Juan's dog}}{\text{Peter's dog}}=\frac{27in}{9in}=3[/tex]Therefore, Juan's dog is 3 times taller than Peter's dog.
1. Squares with side lengths 6, 8, and 10 meters?2. Squares with areas 64 in?, 100 in?, 144 in2? 3. Two squares with side length 5 feet and a square with area 50 square feet?4. Explain how you know whether three squares will join at their corners to form a right triangle.
In order to know if 3 squares will form a right triangle,
a. The sum of the length of two of the squares must be greater than the length of the last square.
b. The lengths of the squares (if they are integers) must form a Pythagorean triple.
Pythagorean triples are:
3, 4, 5
5, 12, 13
8, 15, 17
9, 40, 41
there are more triples but we only need these for this question
c. They must conform to the Pythagoras Theorem.
[tex]\begin{gathered} \text{Pythagoras theorem is:} \\ c^2=a^2+b^2 \\ \text{where c is the largest side of the right angled triangle or hypothenus} \\ \text{while a and b are adjacent and opposite of the right angled triangle} \end{gathered}[/tex]Now we can proceed with these points at hand.
1. Squares with side lengths 6, 8, 10 can be written as:
2(3), 2(4), 2(5).
Ignoring the "2", we can see that this follows the Pythagorean triple.
therefore, 6, 8, 10 can form a right-angled triangle
2. 64, 100, 144 can be written as:
4(16), 4(25), 4(36)
Ignoring the "4", we can see that this does not follow the Pythagorean triple.
If we input the values into the Pythagoras theorem, we shall have:
[tex]\begin{gathered} 64^2+100^2\text{ = 4096 + 10000 = 14096} \\ 144^2=\text{ 20736} \\ \text{Therefore, we can s}ee\text{ that:} \\ 64^2+100^2\text{ }\ne\text{ }144^2 \end{gathered}[/tex]Therefore, 64, 100, 144 cannot form a right-angled triangle
3. Two squares with lengths 5 and a Square with an area of 50 square feet:
We need to find the length of the square with an area of 50 square feet.
[tex]\begin{gathered} \text{Area of square = l}^2 \\ \text{where l is the length of the side} \\ 50=l^2 \\ \text{square root both sides} \\ l\text{ = }\sqrt[]{50\text{ }}\text{ = 5}\sqrt[]{2} \end{gathered}[/tex]Now that we know the length of the 3rd and largest side of this triangle, we can now determine whether it is a right-angled triangle.
This case has a non-integer as part of the sides of the triangle, thus, condition b does not apply.
We must check via Pythagoras theorem:
[tex]\begin{gathered} By\text{ pythagoras:} \\ 5^2+5^2=25+25=50 \\ \text{while,} \\ (5\sqrt[]{2})^2=5^2\times(\sqrt[]{2})^2=25\times2=50 \\ \text{Thus we can s}ee\text{ that:} \\ 5,5,5\sqrt[]{2}\text{ can form a right-angled triangle} \end{gathered}[/tex]Therefore, the final answer: 1 and 3 can form a right-angled triangle but 2 cannot
4. I have given the reasons why they form a right-angled triangle above. But let me restate them:

What is absolute value?Without taking direction into account, absolute value defines how far away from zero a certain number is on the number line. A number can never have a negative absolute value.
By deducting 1, you may determine the numbers' decreasing order. To write the numbers 10 to 6 in descending order, for instance, we would start with 10, the greatest number in the preceding series, and continue taking away 1 until we reached the lowest number.
There are 4 lists given from which it is obtained only list A is only in which the numbers are in descending order,
|-6(5/7)| = +6.71

Arc length s. Central Angle 36 feet. π/2 radiansFind the radius r of a circle with an arc length s and a central angle 0.
The formula for determining the length of an arc is expressed as
length of arc = #/360 * 2 * pi * radius
where
# represents the central angle
From the information given
length of arc = 36
We would convert from radians to degree
1 pi rad = 180 degrees
pi/2 rad = 180/2 = 90 degrees
Thus, # = 90 degrees
The equation becomes
36 = 90/360 * 2 * pi * radius
36 = 0.25 * 2 * 3.14 * radius
36 = 1.57 * radius
radius = 36/1.57

When Fowler inc, just paid a dividend, the price in 15 years for the share is $72.36.
How to calculate the price?This will be illustrated as:
P0 = D1 / (Ke - g)
P0 = Current Price
D1 = Expected Dividend after 1 Year
Ke = COst of Equity
g = Growth Rate
Dividend for first year will be:
D1 = D0(1+g)
= $ 2.55 (1+0.039)

Current price will be:
P0 = D1 / (Ke - g)
= $ 2.6495 / (0.104-0.039)
= $ 2.6495 / 0.065
= $ 40.76
Price in 15 years will be
P15 = D16 / (Ke - g)
P15 = Price after 15 Years
D16 = Expected Div after 16 Years
Ke = COst of Equity
g = Growth Rate
D16 = D0(1+g)^16
= $ 2.55 (1+0.039)^16
= $ 2.55(1.039)^16

A travel agent arranged a payment plan for a client. It required a down payment of $150 and 15 monthly payments of $657. What was the total cost of the plan?
Answer:
$10,005
Step-by-step explanation:
We need to find the total cost of the plan and we already know that the client need to pay $150 for downpayment and 15 monthly payments of $657.
So all we need to find is the 15 monthly payments of $657. (Which we could found with multiplying $657 with 15)
$657×15 = $9,855
Now we just add it with the downpayment ($150) to find the total cost of the plan.
$9,855+$150 = $10,005
You could write the steps like this:
$150+($657×15)=$10 005
