What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between the sides and angles of triangles.
Using Trigonometry,
cos 25 = B/ H
cos 25 = 10 / x
0.906 = 10/ x
x= 10/ 0.906
x= 11.037
Hence, the value of x is 11.037.

Answer:
hope this helps!
Step-by-step explanation:
The inverse function of the given function will be f(x)⁻¹ = ( 10 ) / ( 9x - 99).
What is an inverse function?A function is defined as the expression that set up the relationship between the dependent variable and the independent variable. In an inverse function, the value of two variables x and y are interchanged, and then the value of y is given an inverse function.
Given function is f(x) = ( 10/9x) + 11. the inverse function will be calculated as below:-
y = 10/9x+11
x = ( 10 / 9y ) + 11
x - 11 = ( 10 / 9y )
9y / 10 = ( 1 / ( x - 11 )
9y = 10 / ( x - 11 )
y = ( 10 ) / ( 9x - 99 )
Therefore, the inverse function of the given function will be f(x)⁻¹ = ( 10 ) / ( 9x - 99).

Express 8^1/2 in simplest radical form.
Final answer:
To express [tex]8^{1/2[/tex]in simplest radical form, recognize that it's equivalent to the square root of 8, then simplify to 2√2 by breaking down 8 into prime factors and finding pairs of factors.
Explanation:
To express [tex]8^{1/2[/tex] in simplest radical form, we follow these steps:
Recognize that an exponent of 1/2 is equivalent to the square root.
Find the square root of 8, which can also be written as √8.
Since 8 is not a perfect square, we can simplify it by breaking it down into its prime factors: 8 = 2 x 2 x 2.
Group the factors into pairs to determine the square root: 8 has one pair of 2s.
This pair comes out of the radical as a single 2, leaving one 2 inside the radical: 2√2.
Therefore, 8^1/2 simplifies to 2√2, which is the simplest radical form.

How long would it take a bus traveling at 52 km/h to travel 130 km ??
Answer: 2.5 hours
Step-by-step explanation:
130 / 52 = 2.5
A bus will take "2.5 hours" to travel.
Given that:
Speed of bus (s),
= 52 km/h
Distance (d),
= 130 km
As we know,
→ [tex]Speed = \frac{Distance}{Time}[/tex]
or,
→ [tex]Time = \frac{Distance }{Speed}[/tex]

79.99 - 12% + 8%
please dhow your work
thank you
And be safe
Answer:
79.95
Step-by-step explanation:
The first step is to rewrite the percentages into decimals so they can be added or subtracted easier. To turn a percentage into a decimal, remove the percent sign and move the decimal two spaces to the left (in other words, divide the number by 100).
12% becomes -0.12
8% becomes 0.08
Now, let's solve.
79.99 - 0.12 + 0.08
Evaluating 79.99 - 0.12, the equation becomes 79.87 + 0.08.
Evaluating 79.87 + 0.08, we get the final answer, 79.95.

13. In a week the prices of a bag of rice were 350,280,340,290,320, 310,300. The range is
A. 60
B. 70
C. 80
D. 100
so the right answer is 70.
Look at the attached picture ⤴
Hope it will help u
Answer:
B
Step-by-step explanation:
The range can be found by subtracting the lowest number from the highest number
First, arrange the numbers in order from least to greatest
350,280,340,290,320, 310,300
280, 290, 300, 310, 320, 340, 350
So, our lowest number is 280, and our highest is 350.
highest number - lowest number
Subtract 280 from 350
350-280
70
So, our range is 70, making B the correct answer
Metric countries rate the fuel efficiency of a car by the number of liters of gasoline required to drive 100 kilometers. If a car takes 9 liters per 100 kilometers, what is its efficiency in miles per gallon? Use the conversions 1 gal= 3.7854 L and 1 mile = 1.6 km.
WILL MARK BRAINLIEST
The efficiency of the car in unit miles per gallon will be 26.28.
What is unit conversion?To convert any unit into another is called a unit conversion.
In order to convert units, we need to care about their dimensions their dimension should not be changed.
Given that,
The car takes 9 liters per 100 kilometers
9 liters ⇒ 100 km
Since 1 gal= 3.7854 L → 1 L = (1/3.7854) gal
9 L = (9/3.7854) gal
1 mile = 1.6 km → 1 km = (1/1.6) miles
100 km = (100/1.6) miles
So, (9/3.7854) gal ⇒ (100/1.6) miles
Efficiency = (100/1.6) ÷ (9/3.7854)
Efficiency = 26.28 miles/gal
Hence "The efficiency of the car in unit miles per gallon will be 26.28".

The interior angles in a triangle have a sum of 180 degrees. You can also prove it by the Sum of Interior Angles formula:
S= (n-2)·180.
n- the number of sides in the polygon
S= the total sum of interior angles.
Answer:
The sum of three interior angles always have to have the sum of 180 degrees. So with that being said, each of the angles have to be less than 180 degrees.

Step-by-step explanation:
Joseph is ordering a taxi from an online taxi service. The taxi charges $4 just for the
pickup and then an additional $1 per mile driven. How much would a taxi ride code if
Joseph is riding for 9 miles? How much would a taxi ride cost that is m miles long?
Answer: $13 for the 9 mile ride.
The taxi ride that is m miles long would cost as follows: 4 + m
Step-by-step explanation:
The cost of Joseph's taxi ride is calculated by adding a flat fee of $4 to $1 for each mile driven. Thus, a 9-mile ride would cost $13. For a ride of m miles, the cost would be $4 plus $1 per mile.
Explanation:The cost of a taxi ride can be determined using a function that considers two components: a flat fee, and a rate per mile. In Joseph's case, the online tax service charges a $4 flat fee for pickup, and $1 per each mile driven. Hence, the equation for the cost of a taxi ride (C) for Joseph is as follows: C= 4+1*m.
For a ride of 9 miles, we would substitute m with 9: C = 4+ 1*9, which simplifies to C = $13. Therefore, a 9-mile ride would cost $13.
For a taxi ride that is m miles long, the cost would be C = 4 + 1*m. The 4 represents the flat fee, and the 1*m represents the cost per mile that is driven multiplied by the number of miles in the ride. Therefore, a taxi ride that is m miles long would cost $4 plus $1 per mile.

Using Indices Law :
[tex] \sqrt{a} \times \sqrt{b} = \sqrt{ab} [/tex]
[tex] \sqrt{ - 6} \times \sqrt{ - 10} [/tex]
[tex] = \sqrt{ - 6 \times - 10} [/tex]
[tex] = \sqrt{60} [/tex]
Next, you have to find the common factors of 60 :
60 = 1×60
60 = 2×30
60 = 3×20
60 = 4×15
60 = 5×12
60 = 6×10
In order to simplify, we have to choose a perfect square from the factors above. In the factors above, 4 is a perfect square so that we can square root it :
[tex] \sqrt{60} [/tex]
[tex] = \sqrt{4 \times 15} [/tex]
