Answer:
x = 30
Step-by-step explanation:
Using the sine ratio in the right triangle
sinx = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{2.5}{5}[/tex] = [tex]\frac{1}{2}[/tex] , then
x = [tex]sin^{-1}[/tex] ([tex]\frac{1}{2}[/tex] ) = 30

rotate the given triangle 180° counterclockwise about the origin. Help!!!!
Answer: (read vertically) [0,0/3,-1/-5,-2]
Step-by-step explanation:
[-1, 0] times [0, -3, 5]
[0, -1] [0, 1, 2]
hopefully this makes sense.
The rotated triangle by 180° counterclockwise about the origin is [tex]\left[\begin{array}{ccc}0&3&-5\\0&-1&-2\end{array}\right][/tex]
How to rotate the triangle?The coordinates of the triangle are given as:
[tex]\left[\begin{array}{ccc}0&-3&5\\0&1&2\end{array}\right][/tex]
The rotation is given as:
180° counterclockwise about the origin.
The rule of 180° counterclockwise about the origin is:
(x,y) ⇒ (-x,-y)
Using the above rule, we have:
[tex]\left[\begin{array}{ccc}0&3&-5\\0&-1&-2\end{array}\right][/tex]
Hence, the rotated triangle is [tex]\left[\begin{array}{ccc}0&3&-5\\0&-1&-2\end{array}\right][/tex]

Side YQ and side XP are altitudes to the congruent sides of isosceles triangle WXY. Keisha is going to prove side YQ ≅ side XP by showing they are congruent parts of the congruent triangles QXY and PYX.
By the triangle congruence we can use the SSA method to prove the base angles are congruent.
What do you mean by congruent triangles?If two or more triangles are congruent, it depends on how big their sides and angles are. The three sides and three angles of a triangle determine its size and shape, accordingly. Two triangles are said to be congruent if the pairings of respective sides and corresponding angles are equal.
These are exactly the same size and shape. There are several different congruence conditions that triangles might meet.
In the figure given,
It is necessary to demonstrate the congruence of the triangles PYX and QXY.
Both triangles have the same XY base.
PX must equal QY because the lines PX and QY are perpendicular on congruent sides.
Angles PYX and QXY are equal since the axiom "Angles opposed to equal sides are equal" states that they are.
As a result, it can be shown that the two triangles PYX and QXY have two sides and an equal angle.
As a result, using SSA criteria, the two triangles will be congruent.
Hence, option C is the best one.

Mike went to a football game with his family. They bought 5 boxes of popcorn and 3 programs, and spent $41. Sean's family went to the same game, bought 3 boxes of popcorn and 2 programs, and spent $26. How much does each program cost at the game?
Answer:
$7
Step-by-step explanation:
Let the price of a box of popcorn = b and the price of a program = p
we can make 2 equations:
5b+3p = 41 and 3b+2p=26
We can use the subtraction method be able to eliminate one of the variables and isolate the other one - to do it I will equalize the 'b' in both equations by multiplying by 5 and 3 respectively
5(3b+2p=26)
-3(5b+3p = 41)
15b+10p=130
-(15b+9p=123)
p=7 (therefore the answer is 7$)

A store sold 655 bicycles last year. This year the store sold 582 bicycles. What is the percent of change in the number of bicycles sold from last year to this year? Round to the nearest percent
Answer:
12.5%
Step-by-step explanation:
Given data
Number of bicycles sold last year= 655
Number of bicycles sold this year= 582
%percent change= Iniitial -FInal/initial *100
%percent change= 655-582/582*100
%percent change= 73/582 *100
%percent change=0.125 *100
%percent change=12.5%
Hence the percent change is 12.5%

Step-by-step explanation:
2) a) You have to find the area of semicircle.
r = d/2 = 12/2 = 6 mm
Area of semicircle = [tex]\frac{1}{2}\pi r^{2}[/tex]
[tex]= \frac{1}{2}*3.14*6*6\\\\= 3.14*3*6\\\\= 56.52 mm^{2}[/tex]
b) r = 10 cm
Area of quadrant = [tex]\frac{1}{4}\pi r^{2}[/tex]
[tex]= \frac{1}{4}*3.14*10*10\\\\=3.14*5*5\\\\= 78.5 cm^{2}[/tex]
3) d = 10 m
r = d/2 = 10/2 = 5 m
Area of circular garden = πr²
= 3.14 * 5 * 5
= 78.5 m²
Area of rectangular pool = 8 * 6 = 48 m²
Area of the garden covered in grass = area of the circular garden - area of pool
= 78.5 - 48
= 30.5 m²
4) a) r = 60 cm
Area of the top of the circular table = πr²
= 3.14 * 60 * 60
= 11304 cm²
diameter of base = 30 cm
r = 30/2 = 15 cm
Area of circular base = 3.14 * 15 * 15
= 706.5 cm²

4. What is the half-life of the radioactive isotope with amount A, whose rate of decay in t hours is shown in the graph below?
(0,40)
(20,15)
Answer:
15, 25
Step-by-step explanation:
Answer:The half life is the time taken for the amount of a substance to become half of its original value. If we take the initial value to be 30 on the y-axis, the half of 30 is 15. We check the time at which the substance has reduced to 15 atoms and this is about 40 seconds. The answer is C.

the surface area of the rectangular prism is given by formula S=2 (ab+bh+ah) find the value of h when a = 10, b=6 and s=440
Answer:
10
Step-by-step explanation:
440=2(60+6x+10x)
220=60+16x
160=16x
x=10
h=10
The required value of h is 10 which is determined by substituting the values of a = 10, b = 6, and s = 440 in the formula the surface area of the prism of S = 2 (ab+bh+ah).
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operations.
We have been given data as:
a = 10, b = 6 and s = 440
The surface area of the rectangular prism is given by the formula
⇒ S = 2(ab + bh + ah)
Substitute the values of a = 10, b = 6 and s = 440 in the above formula
⇒ 440 = 2(60 + 6h + 10h)
⇒ 220 = 60 + 16h
⇒ 220 - 60 = 16h
⇒ 160 = 16h
⇒ 16h = 160
⇒ h = 160/16
⇒ h = 10
Therefore, the required value of h is 10.

Answer:
Tom will need 42 bags of seed.
Step-by-step explanation:
The area of Tom's yard is 630 square feet.
Divide the area (630) by the amount of area that each bag of seed covers (15)
630 divided by 15 is 42. So, Tom will need to use 42 bags of seed to cover his whole yard.
what is the prime factorization of 693
Answer:
The prime factors of 693 are 3, 7, 11.
Hope this helps!
The prime factorization of 693 can be written as [tex]3^2 * 7^1 *11^1[/tex] where 3, 7, 11 are prime numbers.
What is Prime Factorization?In prime factorization, a number is expressed as a product of its prime factors. A prime number is a number which has exactly two factors, 1 and the number itself.
The process in which we write a number as the product of prime numbers is prime factorization. Prime numbers are the numbers that have only two factors, 1 and the number itself. For example, 2, 3, 5, 7, 11, 13, 17, 19, and so on are prime numbers.
For above given examples,
The prime factorization of 693 can be written as [tex]3^2 * 7^1 *11^1[/tex] . In this case 3, 7, 11 are prime numbers.
Thus, the prime factorization of 693 can be written as [tex]3^2 * 7^1 *11^1[/tex] where 3, 7, 11 are prime numbers.
