The area is 9,600 square yards.
Carrie's walk forms a right-angled triangle, with the two legs being her north and west paths, and the hypotenuse being the diagonal path back to the start. To find the area of the triangle, we can apply the formula for the area of a right-angled triangle, which is (1/2) * base * height. In this case, the base is her westward walk (80 yards), and the height is her northward walk (240 yards).
Using the formula, the area equals: (1/2) * 80 yards * 240 yards, yielding an area of 9,600 square yards.

Alex swims in a 400-m freestyle competition at an average speed of 1 1/3 m/s. If he increases his average speed to 1.6 m/s, how much less time will he take?
50 seconds
Recall the equation
d=rt
Distance = rates times time.
We have a single distance, 400m
We have two different rates 1 1/3 m/s and 1.6 m/s
Let's calculate the time for each rate
t = d/r
t = 400/(1 1/3) = 300 seconds
t = 400/1.6 = 250 seconds
By increasing his average speed, Alex will reduce his time by
300-250 = 50 seconds.

30-60-90 theorem, usually x is used to explain but I will use y since x is in your problem, just substitute any variable for y
in a 30 -60 -90 triangle
the length opposite the 30 degrees is y
the length opposite the 60 degrees is y[tex]\sqrt{3}[/tex]
the length opposite the 90 degrees is 2y
since y[tex]\sqrt{3}[/tex] = 6
y = 6/[tex]\sqrt{3}[/tex]
rationalizing the denominator
[tex]\frac{6}{\sqrt{3} } *\frac{\sqrt{3}}{\sqrt{3}}[/tex] = [tex]\frac{6\sqrt{3} }{3} = 2\sqrt{3}[/tex]
if y = [tex]2\sqrt{3}[/tex], 2y = [tex]4\sqrt{3}[/tex]
Find the value of 10! / (10-2) !
Answer:
The answer is 90
The value of the 10!/(10 - 2)! is 90 after simplification of the factorial option (C) 90 is correct.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
We have given an expression:
10!/(10 - 2)!
The sign '!' represents the factorial of the number.
As we know,
If factorial of any number can be evaluated:
n! = n(n - 1)(n - 2)(n - 3)(n - 4).......1
10! = 10×9×8×7×6×5×4×3×2×1
or
10! = 90(8!)
(10 - 2)! = 8!
= 90(8!)/(8)!
90
8! is canceled out from the numerator and denominator
Thus, the value of the 10!/(10 - 2)! is 90 after simplification of the factorial option (C) 90 is correct.

What is the constant of proportionality in the equation, Y=4.50x?
Solution:
Given that,
[tex]y = 4.50x[/tex]
We have to find the constant of proportionality in the equation
We know that,
When y varies directly with x, then
[tex]y \propto x\\\\y = kx ---- eqn\ 1[/tex]
Where, "k" is constant of proportionality
From given,
y = 4.50x
Compare the above equation with eqn 1,
k = 4.50Thus, constant of proportionality in the equation y = 4.50x is 4.50
Which expression is equivalent to 30 divided by (3+x )
The expression 30 divided by (3+x) is already presented in its simplest form which is 30 / (3 + x).
The question which expression is equivalent to 30 divided by (3+x) pertains to the simplification of algebraic expressions, a basic concept in algebra. To solve or simplify this expression directly, it remains 30 / (3 + x), as there is no further simplification that can be done without additional context or constraints on the variable x. In algebra, expressions are simplified or manipulated using algebraic rules, but in this case, the expression is already in its most simplified form unless specific values are provided for x.
You jump off a 24 foot high cliff and your fall is modeled by the function:
h(t) = -16t2 + 8t + 24
When would you reach 16 feet above the water?
A. 1/4 second
B. 1 second
C. 1/2 second
D. 8 seconds
Answer: B) 1 second
Step-by-step explanation:
plug 16 (final height) into the equation given:
16=-16t^2+8t+24, and solve for t.
x will equal -1/2 or 1
disregard the negative because you can’t have time.
To reach 16 feet above the water, you would reach that height after approximately 1/2 second. Option C
To find when you would reach 16 feet above the water, set the function h(t) equal to 16 and solve for t:
-16t2 + 8t + 24 = 16
Combine like terms to get:
-16t2 + 8t + 8 = 0
Now, you can use the quadratic formula to solve for t:
t = (-b ± √(b2 - 4ac)) / (2a)
Plug in the values of a, b, and c from the equation:
t = (-8 ± √(82 - 4(-16)(8))) / (2(-16))
Simplify the expression inside the square root and solve for t to get the answer:
t ≈ 1/2 second
Option C

company 2 charges 4600$ for the first 550 feet of fence and 29 for each additional feet.find the cost if company 2 completes the job the total fence is 660
To calculate the total cost for a 660 feet fence by Company 2, subtract the initial 550 feet covered by the flat fee from the total length, multiply the additional feet by the per-foot cost, and add the flat fee to get the final cost, which is $7790.
Explanation:The student is asking about calculating the total cost for installing fencing, which involves initial fees and additional per unit costs. In this case, Company 2 charges a flat fee for the first 550 feet of fence and then an additional fee for each foot beyond that.
To find the total cost when Company 2 installs a fence of 660 feet, we first calculate the number of feet beyond the initial 550 feet. This is 660 - 550 = 110 feet. Then, we multiply the additional feet by the cost per additional foot: 110 feet x $29/foot = $3190.
Lastly, we add the initial flat fee of $4600 to the cost for the additional feet to get the total cost: $4600 + $3190 = $7790.

Chase plans to buy a new car and determines he can budget $725 monthly for four years. His bank is
offering an 8.25% annual interest rate. What is the maximum loan he can afford to stay in his budget?
Use the formula, A – P/(1+) -11
, where P is the month payment, r is the annual interest rate, n is
the nur
the number of times interest is compounded in one year, and t is the number of years.
O A. $26,000.50
B. $29,555.50
C. $37.425.75
O
D. $52,500.00
Answer:
The correct answer is B. $ 29,555.50
Step-by-step explanation:
Let's calculate A, using the formula provided, this way:
A = P * [(1 + r)ⁿ - 1]/r * (1 + r)ⁿ, where:
P is the month payment = 725
r is the monthly interest rate = 0.0825/12 = 0.006875
n is the the number of months to pay = 4 * 12 = 48
Replacing with the values we know, we have:
A = P * [(1 + r)ⁿ - 1]/r * (1 + r)ⁿ
A = 725 * [(1 +0.006875 )⁴⁸ - 1]/0.006875 * (1 +0.006875 )⁴⁸
A = 725 * 0.38939833/0.006875 * 1.38939833
A = 282.313789/0.009552114
A = 29,555.50
The correct answer is B. $ 29,555.50
The correct option is B. [tex]\$29555.50[/tex]. The maximum loan Chase can afford, while making monthly payments of [tex]\$725[/tex] for [tex]4[/tex] years at an [tex]8.25\%[/tex] annual interest rate.
Given:
Monthly payment [tex]\( P = $725 \)[/tex]
Annual interest rate [tex]\( r = 8.25\% \)[/tex] or [tex]\( 0.0825 \)[/tex] as a decimal
Number of payments per year [tex]\( n = 12 \)[/tex] (since monthly payments)
Number of years [tex]\( t = 4 \)[/tex]
The formula to calculate the present value [tex]\( A \)[/tex] of the loan is:
[tex]\[ A = P \times \frac{1 - (1 + \frac{r}{n})^{-nt}}{\frac{r}{n}} \][/tex]
Now, substitute the given values
[tex]\[ A = 725 \times \frac{1 - (1 + \frac{0.0825}{12})^{-12 \times 4}}{\frac{0.0825}{12}} \][/tex]
First, calculate [tex]\( \frac{r}{n} \)[/tex]
[tex]\[ \frac{0.0825}{12} = 0.006875 \][/tex]
Next, calculate [tex]\( (1 + \frac{r}{n})^{-nt} \)[/tex]
[tex]\[ (1 + 0.006875)^{-48} = 0.7221 \][/tex]
Now substitute these values into the formula for [tex]\( A \)[/tex]
[tex]\[ A = 725 \times \frac{1 - 0.7221}{0.006875} \][/tex]
[tex]\[ A = 725 \times \frac{0.2779}{0.006875} \][/tex]
[tex]\[ A = 725 \times 40.4218 \][/tex]
[tex]\[ A = 29555.50 \][/tex]

Slope of the line passing through the points (-3,3) and (5,9)
Answer:
m=3/4
Step-by-step explanation:
Slope is equal to the change in y over the change in x, or rise over run.
m=change in y/change in x
The change in x is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise).
m=y2−y1/x2−x1
Substitute in the values of x and y into the equation to find the slope.
m=9−(3)/5−(−3)
Simplify.
m=3/4
The slope of the line passing through the points (-3,3) and (5,9) is 3/4
The formula for calculating the slope of a line is expressed as:
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\[/tex]
Given the coordinate (-3,3) and (5,9), substitute the coordinates into the formula as shown below;
[tex]m=\frac{9-3}{5-(-3)}\\m=\frac{6}{5+3} \\m=\frac{6}{8}\\m=\frac{3}{4}[/tex]
Hence the slope of the line passing through the points (-3,3) and (5,9) is 3/4
