Answer:
[tex]\boxed {\boxed {\sf x\approx 7.3}}[/tex]
Step-by-step explanation:
The triangle has a small square in the corner representing a 90 degree angle. This is a right triangle so we can use the Pythagorean Theorem to solve for the sides.
[tex]a^2+b^2=c^2[/tex]
In this equation, a and b are the legs and c is the hypotenuse.
x and 8.5 are the legs because they make up the right angle. 11.2 is the hypotenuse because it is opposite the right angle.
a= xb=8.5 c=11.2Substitute the values into the formula.
[tex]x^2+(8.5)^2=(11.2)^2[/tex]
Solve the exponents.
(8.5)²= 8.5*8.5= 72.25 (11.2)²= 11.2*11.2= 125.44[tex]x^2+72.25 =125.44[/tex]
Solve for x by isolating the variable. 72.25 is being added, so we subtract 72.25 from both sides because subtraction is the inverse operation of addition.
[tex]x^2+72.25-72.25 = 125.44-72.25[/tex]
[tex]x^2=125.44-72.25[/tex]
[tex]x^2=53.19[/tex]
x is being squared, so we take the square root of both sides.
[tex]\sqrt{x^2}=\sqrt {53.19}[/tex]
[tex]x=\sqrt{53.19[/tex]
[tex]x=7.29314746869[/tex]
Round to the nearest tenth. The 9 in the hundredth place tells us to round the 2 up to a 3.
[tex]x \approx 7.3[/tex]
The unknown side, x, is approximately 7.3

The vertices of a convex pentagon are $(-1, -1), (-3, 4), (1, 7), (6, 5)$ and $(3, -1)$. What is the area of the pentagon
On solving the provided question, we can say that vertices of pentagon are (-1, -1), (-3, 4), (1, 7), (6, 5) and (3, -1); Area = 30 sq unit
what is a pentagon?A pentagon is a polygon with five sides that is used in geometry. The inner angles of a straightforward pentagon add up to 540°. Simple or self-intersecting pentagons are both possible. A pentagram is a self-intersecting regular pentagon. Five angles and all sides of a regular pentagon are equal. It is referred to as an irregular pentagon if the side lengths and angle measurements do not match. All outside angles, as far as we are aware, balance out inside angles. The polygon's exterior angle total is therefore equal to n(360°/n). There are five sides to a pentagon, therefore n must equal five. Consequently, 5(360°/5) = 360° is the sum of the pentagon's outer angles.
vertices of a convex pentagon are (-1, -1), (-3, 4), (1, 7), (6, 5) and (3, -1).
Area = 1/2 [ 24+3+15+0-3] - [3-30-3+9-0]
Area = 1/2| 60 |
Area of pentagon = 30 sq unit

the perimeter of a right triangle is 24 ft, and one of its legs measures 6 ft. Find the length of the other leg and the hypotenuse.
a) 6 ft, 12ft
b) 5 ft, 13 ft
c) 8 ft, 10 ft
d) 7 ft, 11 ft
Answer:
Step-by-step explanation:
We know the perimeter of a triangle is the sum of all the sides( two legs and one hypotenuse).
By pythagoras we know that
[tex]h^2= a^2+b^2.[/tex]
and the perimeter is [tex]P=h+a+b[/tex].
Since P=24 and a=6 we have these equations:
[tex]h^2=36+b^2\\24=h+6+b[/tex]
From the last equation we have [tex]h=18-b[/tex]. Replace h in the first equation we get that
[tex](18-b)^2=36+b^2[/tex]
[tex]18^2-36b+b^2=36+b^2\\288=36b\\b=\frac{288}{36}=8[/tex]
and h=18-8=10

Galle bought a purse for $22.50. Gale's thend Brenda saw the purse and said she would give Gale $35 if Gale would sell her the new purse right then.
mely how much profit as a percent did Gale make from selling the purse to Brenda?
A.35.7%
B.55.6%
C.64.3%
D.155.6%
So Gale made a profit of 55.6% by selling the purse to Brenda. Therefore the correct answer would be B. 55.6%
What is profit and loss?Profit and Loss is a financial statement that shows a company's revenue, costs, and expenses over a certain period of time, such as a month or a year. The purpose of a P&L statement is to show the company's financial performance and to determine whether the company is making a profit or incurring a loss.
What is Profit Percentage?The proportion that the retailer makes after selling a good at a price greater than its cost is the product's profit margin. P% indicates it.
Profit Percentage P% = {(selling price – cost price) / cost price} x 100.
The selling price of the purse is $35 and the original cost of the purse is $22.50. So the profit is $35 - $22.50 = $12.50
Profit as a percent = (Profit / Original cost) * 100
Profit as a percent = ($12.50 / $22.50) * 100 = 55.6%
So Gale made a profit of 55.6% by selling the purse to Brenda. Therefore the correct answer would be B. 55.6%

Suppose that ƒ(−1)=10 and ƒ'(x)≥−3 for all values of x. What is the least possible value of ƒ(3)?
Using the mean value theorem, the least possible value of f(3) is - 2
What is the mean value theorem?The mean value theorem states that for a function f(x) on the interval (a, b), there exists a value c such that
f'(c) = f(b) - f(a)/(b - a)
How to find the least possible value for f(3)?Since ƒ(−1) = 10 and ƒ'(x) ≥−3 for all values of x, we require the least possible value of f(3).
Using the mean value theorem where
b = 3, a = -1 and f'(c) ≥ 3.We choose f'(c) = 3 since f'(x) = 3 is the minimum value of f'(x).
So, substituting the values of the variables into the equation, we have that
f'(c) = f(b) - f(a)/(b - a)
f'(x) = f(3) - f(-1)/(3 - (-1))
f'(x) = f(3) - f(-1)/(3 + 1)
f'(x) = f(3) - f(-1)/4
So, making f(3) subject of the formula, we have that
f(3) = f(-1) + 4f'(x)
Since
f'(x) = 3 and f(-1) = 10,Substituting the values of the variables into the equation, we have that
f(3) = f(-1) + 4f'(x)
f(3) = 10 + 4(-3)
f(3) = 10 - 12
f(3) = - 2
So, the least possible value is - 2

The ratio of the measures of three sides of a triangle is 1/4:1/3:1/6. its perimeter is 31.5 inches
Answer:
10.5 inches, 14 inches, 7 inches
Step-by-step explanation:
Let's say x is the multiplier of the ratio value and the actual length of the sides:
1/4 * x = side 1
1/3 * x = side 2
1/6 * x = side 3
Since the perimeter is the sum of all sides, the perimeter is equal to:
31.5 = 1/4 * x + 1/3 * x + 1/6 * x ==> 31.5 inches is the perimeter
(31.5 = x/4 + x/3 + x/6)*12 ==> multiply the equation by 12 since 12 is the
LCM (Least Common Multiple) of 4, 3, and 6
12 * 31.5 = 12 * x/4 + 12 * x/3 + 12 * x/6 ==> multiply each term by 12
378 = 12x/4 + 12x/3 + 12x/6 ==> simplify
378 = 3x + 4x + 2x
378 = 9x
x = 378/9 ==> divide both sides by 9
x = 42
Now find each side length [Refer to the first three equations] :
Side length 1: 1/4 * 42 = 42/4 = 10.5 inches
Side length 2: 1/3 * 42 = 42/3 = 14 inches
Side length 3: 1/6 * 42 = 42/6 = 7 inches

How do you check whether 7 3x is a factor of 3x3 7x?
7 + 3x is not a factor of expression 3x^3 + 7x
Consider given expression 3x^3 + 7x
Let f(x) = 3x^3 + 7x
Assume that 7 + 3x is a factor of 3x^3 + 7x
This means, 7 + 3x = 0 would be the root.
x = -7/3
If x = -7/3 is root of polynomial f(x) = 3x^3 + 7x then f(-7/3) must be equal to 0
We find the value of given polynomial for x = -7/3
f(x) = 3x^3 + 7x
f(-7/3) = 3(-7 / 3)^3 + 7 (-7 / 3)
f(-7/3) = (3 × (-343)) / 27 + (-49 / 3)
f(-7/3) = [(-343) - 147] / 9
f(-7/3) = -490 / 9
f(-7/3) ≠ 0
Since f(-7/3) ≠ 0, x = -7/3 is not root of polynomial f(x) = 3x^3 + 7x
