The sine of ∠I is represented by the ratio 63:65
First, let's draw the triangle (see the picture below.)
We need to use it here.
What are trigonometric ratios?-sin = opposite/hypotenuse
-cos = adjacent/hypotenuse
-tan = opposite/adjacent.
Assuming that ∠I is Ф,
we can see that its opposite side is equal to 63 and the hypotenuse is 65. Therefore,
[tex]sin(I)=\frac{63}{65} \\\\sinI=75^0[/tex]

Of the 12.4 million species of organisms in the world today, 64% (almost two thirds) are insects.
Estimate to the nearest million the number of insect species.
Answer:
8 million insect species
Step-by-step explanation:
Solving :
⇒ Number of species = Total organisms × % of the species
⇒ Number of species = 12.4 × 64%
⇒ Number of species = 0.124 × 64
⇒ Number of species = 7.936 million ≈ 8 million insect species
Using only the markings given in the diagram, which triangle congruence criterion can be used to prove that PQR and STU are congruent?
Answer: HL
Step-by-step explanation:
If the hypotenuse and one leg of the two triangles are congruent, then the triangles are congruent. The correct option is D, HL.
What is the HL theorem?According to the HL theorem, If the hypotenuse and one leg of the two triangles are congruent, then the triangles are congruent. therefore, the hypotenuse will be congruent to each other, and the corresponding sides will be congruent to each other.
In the two of the given triangle, ΔPQR and ΔSTU, the following things can be seen,
PR ≅ SU (Leg of the triangle)
RQ ≅ TU (Hypotenuse)
Also, since the two of the triangles are right angle triangle, and the length of the one leg of the two triangles is equal, also, the hypotenuse of the two triangle is equal. Therefore, Using the HL postulate. The two triangles can be said to be congruent.
Hence, the triangle congruence criterion can be used to prove that PQR and STU are congruent is HL Congruency.

The outside of a rectangular picture frame has length 4x + 5 centimeters and width 2x + 3 centimeters. The picture window inside the frame is a rectangle that is 4x - 2 centimeters long and x + 1 centimeters wide.
a. Write a polynomial to describe the area (in square centimeters) of the picture window.
b. The picture frame, not including the window, is made of flat pieces of wood. Write a polynomial that describes the area (in square centimeters) of the wooden part of the frame. Explain your reasoning
The area of the wooden part of the frame is 4x² +20x +17 sq.cm , Area of a Rectangle is 4x² +2x-2 sq.cm .
What is a Rectangle ?A rectangle is a polygon with four sides . The opposite sides are parallel and equal.
It is given that the outside length and breadth is 4x + 5 centimeters and width 2x + 3 centimeters.
inside the frame has length and breadth 4x - 2 centimeters long and x + 1 centimeters wide.
The polynomial to describe the area of the picture window
The dimension of the inner picture frame is the dimension of the picture window
Area of a Rectangle = Length * Breadth
Area of a Rectangle = (4x-2) (x+1) = 4x² +4x -2x-2 = 4x² +2x-2 sq.cm
The picture frame area without the window =
Area of the total picture frame - Area of the inner picture frame
= (4x+5)(2x+3) - (4x-2)(x+1)
= 8x² + 12x +10x+15 -4x²-2x +2
= 4x² +20x +17
The area of the wooden part of the frame is 4x² +20x +17 .

O 27x³ +35mx² +80*x+48
O 27x³ +35x² +1767x+1927
O 47x³+447x² +105x+72
The expression represents the volume of the can is 2x³ + 35x² + 176x + 192.
What is Volume?Volume is a mathematical term that describes how much three-dimensional space an object or closed surface occupies. The measurement for volume is in cubic units, such m3.
Expression: (Math Operator, Number/Variable, Math Operator)
We have,
radius = (x + 8) and, height = (2x + 3)
So, Volume of can
= πr²h
= π(x+8)² (2x+3)
= π (x² + 16x + 64) (2x+3)
= π (2x³ + 3x² + 32x² + 48x + 128x + 192)

What is Charles law?Charles law states that, the volume of a given mass of gas is directly proportional to the temperature at constant pressure.
For problem 1;
T1 = 20 + 273 = 293 K
V1 = 15 dm3
T2 = 318 K
V2 = ?
V1/T1 = V2/T2
V1T2 =V2T1
V2 = V1T2/T1
V2 = 15 dm3 * 318 K/293 K
V2 = 16 dm3
Problem 2
V1 = 250cm3
T1 = 10 + 273 = 283 K

A certain species of animal can has varying fur color. The probability that the animal will have orange fur is 0.7, the probability of brown fur is 0.11 and the probability of grey fur is 0.19. The animal also occasionally will have stripes. If the animal is orange the probability of stripes is 0.16, if the animal is brown the probability of stripes is 0.3, and if the animal is grey the probability of stripes is 0.4.
What is the probability an animal has stripes?
(Round answer to three decimal places)
What is the probability an animal is orange given it does NOT have stripes?
(Round answer to three decimal places)
The probability that an animal has stripes will be 0.86.
How to calculate the probability?The probability that an animal has stripes will be:
= Orange stripes + Brown stripes + Grey stripes
= 0.16 + 0.3 + 0.4
= 0.86
The probability that an animal doesn't have stripes will be:
= 1 - 0.86
= 0.14
Therefore, the probability that an animal doesn't have stripes is 0.14.

The table shows the change in the price of a stock. At the end of the week, the price is $17.17.
The price of the stock after the change in price on Thursday is $16.76.
The price of the stock at the beginning of the week is $16.81.
What are the price changes?The price at the end of the week is a function of the total changes in price and the price at the beginning of the week.
$17.17 = beginning price + 0.21 + 0.09 - 0.03 - 0.02 + 0.11
$17.17 = beginning price + 0.36
Beginning price = $17.17 - 0.36 = $16.81

Building A is 875 feet tall and contains 71 stories. Building B contains 109 stories. If the two buildings have the same number of feet per floor, approximate the height of building B rounded to the nearest foot.
Answer:
Approx. 1343 feet
Step-by-step explanation:
Building A is 71 stories at 875 feet tall. Since the two buildings have the same number of feet per floor, we can divide building A's stories to find the height of 1 story, and then multiply by the stories of building B.
Building A
71 ÷ 71 = 1 story
875 ÷ 71 = 12.32 feet
Each story is approximately 12.32 feet tall
Building B
1 story × 109 = 109 stories
12.32 feet × 109 = 1343.31 feet
Rounded to the nearest foot is 1343 feet.
