The height of the boat floating above the seafloor at high tide is 17.5 feet
Triangle similarity theorem.The ratio of the similar sides of the triangles is equal to a constant. In order to determine how high the boat is, we will use the ratio below;
20/40 =x/35
Determine the value of x
40x = 20 * 35
40x =700
x = 700/40
x = 17.5feet
Hence the height of the boat floating above the seafloor at high tide is 17.5 feet

Answer:
11. A. [tex]\frac{12}{13}[/tex]
12. D. [tex]\frac{35}{12}[/tex]
Step-by-step explanation:
11: Sin is just the side opposite of the angle divided by the hypotenuse of the triangle
Opposite of A = 36
Hypotenuse of the triangle = 39
36/39 = [tex]\frac{12}{13}[/tex]
12. Tan is the side opposite of the angle divided by the side adjacent to the angle
Opposite of C = 35
Adjacent to C = 12
35/12 = [tex]\frac{35}{12}[/tex]

Which expression is not equivalent to 1/3(9y-3)-2y?
Answer:
Step-by-step explanation:
Simplify 1/3(9y-3) - 2y as : 3y - 1 - 2y = y - 1
Expression 1 : 3y - 1 - 2y, can be simplified as y-1 => Equivalent
Expression 2 : 3y + 3 - 2y = y + 3 => Not equivalent
Expression 3 : y - 1 => Equivalent
Expression 4 : 1/3(9y) + 1/3(-3) - 2y = 3y - 1 - 2y = y-1 => Equivalent
So, the answer is the second expression.

Which fact helps you prove the isosceles triangle theorem, which states that the base angles of any isosceles triangle have equal measure?
1. The base angles of an equilateral triangle have equal measure
2. if two sides of a triangle are equal, the third side must be equal to the others
3.If a triangle is equiangular, then it is equilateral.
4.If one angle of a triangle is larger than another angle, then the side opposite the larger angle is longer than the side opposite the smaller angle.
Answer:
4. If one angle of a triangle is larger than another angle, then the side opposite the larger angle is longer than the side opposite the smaller angle.
Step-by-step explanation:
Facts about equiangular/equilateral triangles have little bearing on isosceles triangles.
The one relevant fact from the given list is that larger angles are opposite longer sides. This requires you to conclude that equal angles are opposite equal sides, which is the conclusion of the isosceles triangle theorem.
If 2.85 is written as an improper fraction, what is
the numerator?
Answer:
yes
Step-by-step explanation:
The numerator of the improper fraction 2 + 17/20 (which is the decimal 2.85 written as an improper fraction) is 57.
Here, we have to convert the decimal number 2.85 to an improper fraction.
2.85 has a whole number part of 2.
The decimal part 0.85 can be written as 85/100.
85/100 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 5:
85 ÷ 5 = 17
100 ÷ 5 = 20
So, 85/100 simplifies to 17/20.
The whole number part is 2, and the fraction is 17/20.
So, the improper fraction is:
2 + 17/20.
To find the numerator, multiply the whole number part (2) by the denominator of the fraction (20), and then add the numerator of the fraction (17):
Numerator = (Whole number part × Denominator) + Numerator of the fraction
Numerator = (2 × 20) + 17
Numerator = 40 + 17
Numerator = 57.
So, the numerator of the improper fraction 2 + 17/20 (which is the decimal 2.85 written as an improper fraction) is 57.

a) To find the length of diagonal XT, we can use the distance formula to get [tex]\sqrt{(-3-5)^{2}+(4-(-2))^{2}}=10[/tex]
Since this is a rectangle, XT=YW, meaning YW=10 as well.
b) The area of a rectangle is given by length times width. The length is |-3-5|=8, and the width is |-2-4|=6. So the area is (8)(6)=48.
c) The perimeter is just 2(8+6)=28.
Which of the following shows the extraneous solution to the logarithmic equation below? log Subscript 3 Baseline (18 x cubed) minus log Subscript 3 Baseline (2 x) = log Subscript 3 Baseline 144 x = negative 16 x = negative 8 x = negative 4 x = negative 2.
The extraneous solution of the logarithmic problem [tex]\rm log_3(18x^3)-log_3(2x) = log_3 144[/tex] is -4.
What is Logarithm?A log function is a way to find how much a number must be raised in order to get the desired number.
[tex]a^c =b[/tex]
can be written as
[tex]\rm{log_ab=c[/tex]
where a is the base to which the power is to be raised,
b is the desired number that we want when power is to be raised,
c is the power that must be raised to a to get b.
Solving the function using the basic logarithmic value, we get,
[tex]\rm log_3(18x^3)-log_3(2x) = log_3 144\\\\ log_3\dfrac{(18x^3)}{(2x)} = log_3 144\\\\ log_3(9x^2)= log_3 144\\\\\text{Taking antilog}\\9x^2 = 144\\x = \sqrt{\dfrac{144}{9}}[/tex]
If we solve further we will get that the value of x can be either -4 or 4, if take the value of x as -4, in the beginning then you will get log₃(18(-4)³) as the log of negative value which is impossible.
Hence, x=-4 is an extraneous solution.

Sambriddhi bent a rope to form a circle.If she got the circumference of the circle is 30cm more than its diameter. What was the length of the radius?
easy peasy here we go..
so first circumference = 2π R
now it is given that circumference - 30 cm = Diameter;
Diameter = 2πR - 30 = 2 R { diameter = 2 times Radius}
now solving equations:
2πR -2R = 30
πR - R = 15
R ( π - 1 ) = 15
R ( 22/7 - 1) = 15
R ( 15/7 ) = 15
R = 15 x 7 / 15
R = 7 cm
Mark as brainliest
Answer:
7.01 cm
Step-by-step explanation:
Circumference = 2πr
=> d + 30 = 2πr
=> 2r + 30 = 2πr
=> 2r(π - 1) = 30
=> 2.14r = 15
=> r = 15/2.14

We are given with a equation of Circle and we need to find it's radius and it's equation in standard form . But , let's recall , the standard equation of a circle is [tex]{\bf (x-h)^{2}+(y-k)^{2}=r^{2}}[/tex] where (h,k) is the centre of the circle and radius is r . Proceeding further ;
[tex]{:\implies \quad \sf x^{2}+12y+22x+y^{2}-167=0}[/tex]
Collecting x terms , y terms and transposing the constant to RHS ;
[tex]{:\implies \quad \sf (x^{2}+22x)+(y^{2}+12y)=167}[/tex]
Now , as in standard equation their is a whole square , so we need to develop a whole square in LHS , for which we will use completing the square method , as coefficient of x² and y² is 1 , so adding 121 and 36 to LHS and RHS .
[tex]{:\implies \quad \sf (x^{2}+22x+121)+(y^{2}+12y+36)=167+121+36}[/tex]
[tex]{:\implies \quad \sf (x+11)^{2}+(y+6)^{2}=324\quad \qquad \{\because a^{2}+2ab+b^{2}=(a+b)^{2}\}}[/tex]
[tex]{:\implies \quad \bf \therefore \quad \underline{\underline{\{x-(-11)\}^{2}+\{y-(-6)\}^{2}=(18)^{2}}}}[/tex]

Use the arc length formula to find the length of the curve y = 2 − x2 , 0 ≤ x ≤ 1. Check your answer by noting that the curve is part of a circle.
By using the arc length formula, we will see that the length of the curve is L = 1.48
How to use the arc length formula?
Here we have the curve:
y = 2 - x^2 with 0 ≤ x ≤ 1
And we want to find the length of the curve.
The arc length formula for a curve y in the interval [x₁, x₂] is given by:
[tex]L =\int\limits^{x_2}_{x_1} {\sqrt{1 + \frac{dy}{dx}^2} } } \, dx[/tex]
For our curve, we have:
dy/dx = -2x
And the interval is [0, 1]
Replacing that we get:
[tex]L =\int\limits^{1}_{0} {\sqrt{1 + (-2x)^2} } } \, dx\\\\L \int\limits^{1}_{0} {\sqrt{1 + 4x^2} } } \, dx\\[/tex]
This integral is not trivial, using a table you can see that this is equal to:
[tex]L = (\frac{Arsinh(2x)}{4} + \frac{x*\sqrt{4x^2 + 1} }{2})[/tex]
evaluated from x = 1 to x = 0, when we do that, we will get:
[tex]L = \frac{Arsinh(2) + 2*\sqrt{5} }{4} = 1.48[/tex]
That is the length of the curve.

The length of a room is three times its breadth and its volume is 240 m. The cost of plastering its four walls at Rs. 50 per square meter is Rs. 8000, find the height of the room. (Ans: 5 m)
Ⲁⲛ⳽ⲱⲉⲅ :
5mⲊⲟⳑⳙⲧⳕⲟⲛ :We are given that:
The length of the room is three time it's breadth.Volume of the room is 240m³Cost of plastering 4 walls is Rs.8000Cost of plastering 1 wall is Rs.50Some assumptions:
Let the breadth be x Then length will be 3x Let the height be hUsing Formula:
Volume = l × b × h➙ V = l × b × h
➙ V = x × 3x × h
➙ 240 = 3x² × h ㅤㅤ⸻ ( 1 )
Now, the cost of plastering it's 4 walls is Rs 8000 at the rate of 50 /m². So, we can find the area of the walls of the room by dividing 8000 by 50 i.e:
➙ A = Total cost / cost per m²
➙ 8000 / 50
➙ 800 / 5
➙ 160m²
In a cuboid , there are a pair of two opposite and equal rectangular sides, and area of rectangle is given by :
l × bSo, area of 2 walls along length :
➙ 2 × length × height
➙ 2 × 3x × h
➙ 6xh
Area of 2 walls along breadth:
➙ 2 × breadth × height
➙ 2 × x × h
➙ 2xh
Sum of areas of these four walls will be equal to the area of the walls, that we have find earlier;
➙ ( 6xh ) + ( 2xh ) = 160
➙ 8xh = 160
➙ xh = 160 / 8
➙ xh = 20 ㅤㅤㅤ⸻ ( 2 )
Using equation ( 1 )➙ 240 = 3x²h
➙ x²h = 240 / 3
➙ x × xh = 80
➙ x × 20 = 80 ㅤ[ from equation ( 2 ) ]
➙ x = 80 / 20
➙ x = 4
Using equation ( 2 )➙ xh = 20
➙ 4 × h = 20
➙ h = 20 / 4
➙ h = 5
