Answer: 8.6 Ft^2
Explanation:
First find the area of the WHOLE square in FEET
2.5 x 4.5 = 11.25 ft
Then we need to find the area of the circle
r = radius
The formula is A = 3.14r^2
The radius is .9166, we can tell because the total distance from top to bottom is 22in meaning 1.83333 ft, meaning the diameter is 1.8333, then to get the radius we cut that in half.
A = 3.14(.9166^2
A = 2.64 Ft
Now we need to find the new total area
11.25 - 2.64 = 8.61 in ^2
Now we need to convert it to the nearest tenth of a square foot
8.6 Ft^2
I hope this helped !

What is square root and cube root of a number?
Square root of a number results a number that when square, gives us the previous number.
Similarly, cube root of a number results a number that when cubed, gives us the previous number.
Here, [tex]\sqrt[3]{64}[/tex]² = ∛(64 × 64) = ∛(8 × 8 × 8 × 8 × 8 × 8) = 8 × 8 = 64
[tex]16^{3/2}[/tex] = 4³ = 64
[tex]\sqrt[3]{8^{4} }[/tex] = ∛(8 × 8 × 8 × 8) = ∛(64 × 64) = ∛(4 × 4 × 4 × 4 × 4 × 4) = 4 × 4 = 16
√(16²) = √(16 × 16) = 16
Therefore, [tex]\sqrt[3]{64}[/tex]² and [tex]16^{3/2}[/tex] have the greatest value.

Given the equation of a line y = 5x -16, what is the slope of a line PERPENDICULAR to this line?
Answer:
[tex]-\frac{1}{5}[/tex]
Step-by-step explanation:
Notice that the equation y = 5x - 16 is in slope-intercept form, or [tex]y = mx + b[/tex] format. Whenever an equation is in slope-intercept form, the number in place of the [tex]m[/tex], or the coefficient of the x-term, represents the slope of that line. So, the slope of the given line is 5.
Slopes that are perpendicular to each other are opposite reciprocals. So, we need to find the opposite reciprocal of 5. To do that, write it as a fraction, making it [tex]\frac{5}{1}[/tex]. Then, switch the sign and flip the numerator and denominator. This means that the opposite reciprocal of 5 is [tex]-\frac{1}{5}[/tex], so [tex]-\frac{1}{5}[/tex] is the perpendicular slope.

Hudson went shopping for a new pair of sneakers. The listed price of the pair of sneakers was $29, but the price with tax came to $31.61. Find the percent sales tax.
Answer:
Percent sales tax = 9%
Step-by-step explanation:
Listed price = $29
Price with tax = $31.61
Amount of tax = Price with tax - Listed price
= $31.61 - $29
= $2.61
Find the percent sales tax.
Percent sales tax = $2.61/$29 × 100
= 0.09 × 100
= 9%
Percent sales tax = 9%

Find x and y with ray theorem
Answer:
x = 2
y = 5
Step-by-step explanation:
We can say:
7 corresponds to y
(3 + 7.5) corresponds to 7.5
Plus, we can write a ratio
[tex] \frac{7}{y} = \frac{3 + 7.5}{7.5} [/tex]
[tex] \frac{7}{y} = \frac{10.5}{7.5} [/tex]
Cross multiplying, we can solve for "y",
[tex] \frac{7}{y} = \frac{10.5}{7.5} [/tex]
[tex] \frac{7}{y} = 7 \times 7.5[/tex]
y = 5
Again, using similarly, we can say:
(x + 5) corresponds to 5
(3 + 7.5 = 10.5) corresponds to 7.5
We can write a ratio:
[tex] \frac{x + 5}{5} = \frac{10.5}{7.5} [/tex]
Cross multiplying and with the help of a but algebra, we can solve for "x", shown below:
7.5( x + 5) = 5 x 10.5
7.5x + 37.5 = 52.5
7.5x = 15
x = 2
Katherine buys a tv with a normal price of $200 and she has a 25% off coupon. How much money did she save????
Given:
Normal price of a tv = $200
Coupon = 25% off
To find:
The money saved by Katherine.
Solution:
Katherine buys a tv with a normal price of $200 and she has a 25% off coupon. It means, the money saved by Katherine is 25% of normal price of tv, i.e., $200.
[tex]Saving=25\%\text{ of }200[/tex]
[tex]Saving=\dfrac{25}{100}\times 200[/tex]
[tex]Saving=25\times 2[/tex]
[tex]Saving=50[/tex]
Therefore, the money saved by Katherine is $50.
