The required value of the x in the expression of angle is 19.
An expression of angle is given as 7x + 2 = 135°, the value of the x is to be determined.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
7x + 2 = 135
Simplifying,
7x = 135 - 2
7x = 133
x = 133 / 7
x = 19
Thus, the required value of the x in the expression of angle is 19.

Please mark brainliest
Answer:
So we are given the length, width, and height and we are also told that we need to find the surface area. The formula to finding the surface area of a rectangular prism is [tex]S=2(w*h+l*w+l*h)[/tex]
We just plug in the values and solve
[tex]S = 2(9\ in * 3.5\ in+6\ in * 9\ in + 6\ in * 3.5\ in)[/tex]
[tex]S = 2(31.5\ in^2 + 54\ in^2+21\ in^2)[/tex]

Step-by-step explanation:

I don't know the options of the pull-down menus, so I will give you my best guesses based on the facts :
the domain of a function is the set or interval of all valid x (or input) values.
the range of a function is the set of interval of all valid y (or functional result) values.
so, clearly, x is in the interval (-infinity, +infinity). which is therefore the domain.
please conduct the round brackets. they indicate that the specified interval limits are not included (as infinity is not a value, only a concept, and can never be reached).
and y is in the interval of (0, +infinity). which is therefore the range.
we have to use the round brackets also for 0, as the function will never deliver the value 0, but its tendency or limit goes there (but again, only in infinity, which will never be reached).
the function continuously decreases when x increases.
again, I am not sure what the options are here, and what your teacher wants to "hear".
At an assembly, 7 out of the first 12 students who entered the gym were carrying a backpack. Based on this information, if 648 students were at the assembly, how many students could be expected to be carrying a backpack?
The number of students that are expected to carry a backpack is = 378
Calculation of total number of studentsThe total number of students in the assembly= 648
The number of students that enters the gym =12
The number of students carrying backpack = 7 out of 12
The total number of batches that entered the gym = 648/12 = 54
Therefore, the number of students that are expected to carry a backpack is = 54 ×7 = 378

Michelle started doing a puzzle at 7:50 p.m. She finished the puzzle at 8:34 p.m. How long did Michelle work on the puzzle?
Answer:
44 minutes
Step-by-step explanation:
Given:
Michelle started doing a puzzle at 7:50 p.m. She finished the puzzle at 8:34 p.m.
To Find:
How long did Michelle work on the puzzle?
Solve:
Began Time ⇒ 7:50 p.m
End Time ⇒ 8: 34 p.m
Since they are both p.m we could just subtract 8:34 by 7:50.
But first we know that:
8: 34 the 34 can't be subtracted by 7:50 the 50.
Thus we know that:
1 Hour = 60 minutes
Hence,
changing 8:34 p.m from 1 hour to 60 minutes. Which given us 7:94.
Then,
7:94 - 7:50
= 44
Hence, Michelle work on the puzzle for 44 minutes.

The length of a rectangle is 7 more than the width. The area is 744 sqaure yards, find the length and width of the rectangle
Answer:
Length of rectangle is 31 yards and Width is 24 yards.
Given:
The length of a rectangle is 7 more than the width. The area is 744 sqaure yardsSolution:
Let's assume Width of rectangle be x and Length of rectangle be x + 7 respectively.
Using formula
[tex] \\ \: \: \: \: \pink{ \dashrightarrow \: \: \: \: \sf { \underbrace{Area_{(Rectangle)} = Length × Width }}} \\ \\ [/tex]
On Substituting the required values, we get;
[tex]\\ \: \: \: \: \dashrightarrow \: \: \: \: \sf (x)(x + 7) = 744 \\ \\ \\ \: \: \: \: \dashrightarrow \: \: \: \: \sf {x}^{2} + 7x = 744 \\ \\ \\ \: \: \: \: \dashrightarrow \: \: \: \: \sf {x}^{2} + 7x - 744 = 0 \\ \\ \\ \: \: \: \: \dashrightarrow \: \: \: \: \sf {x}^{2} + 31x - 24x - 744 = 0 \\ \\ \\ \: \: \: \: \dashrightarrow \: \: \: \: \sf x(x + 31) - 24 (x + 31) = 0 \\ \\ \\ \: \: \: \: \dashrightarrow \: \: \: \: \sf (x + 31)(x - 24) = 0 \\ \\ \\ \: \: \: \: \dashrightarrow \: \: \: \: \sf x = 24 \: or \: - 31 \\ \\ [/tex]
As we know that width of the rectangle can't be negative. So x = 24
Hence,
Width of rectangle = x = 24 yardsLength of the rectangle = x + 7 = 31 yards[tex] \therefore[/tex]Length of rectangle is 31 yards and Width is 24 yards.

The substitution that should be used to rewrite 6(x+5)^2 + 5(x+5) - 4 = 0 is u = x + 5
Quadratic equationsThese are equations that has a leading degree of 2. Given the expression
6(x+5)^2 + 5(x+5) - 4 = 0
In order to simplify this equation, we will replace the reoccuring term by a variable.
From the equation we can see that (x+5) is occuring the most. Let u = x + 5 so that:
6u^2 - 5u - 4 = 0

An observer (O) spots a bird flying at a 35° angle from a line drawn horizontal to its nest. If the distance from the observer (O) to the bird (B) is 21,000 feet, how far is the bird (B) from its nest (N)? Round to the nearest whole number. A right triangle BNO is shown with angle B marked 35 degrees, side BN marked x, and side BO marked 21,000 feet.
the answer is 17,202 feet
The bird (B) from its nest (N) is 17202 ft.
What is Trigonometric functions?
Trigonometric functions defined as the functions which show the relationship between angle and sides of a right-angled triangle.
This is very obviously a right triangle problem.
Side BO is the hypotenuse of the triangle, measuring 21000.
Side BN is the side adjacent to the given angle B, 35 degrees.
This is the cosine ratio:
cos∅ = adj/hyp
substitute the values
cos35° = x/21000 and solving for x:
21000.cos(35°) = x
x = 17202.19 or, rounded as we need:
x = 17202
Hence, the bird (B) from its nest (N) is 17202 ft

The mathematics faculty at a college consists of 7professors, 9 associate professors, 9 assistant professors, and 9 instructors. If one faculty member is randomly selected, find the probability of choosing a professor or an instructor.
=============================================================
Explanation:
There are 7 professors and 9 instructors (first and last items mentioned).
So there are 7+9 = 16 people who are either a professor or an instructor, but not both. I'm assuming the job titles do not overlap, ie no one person has more than one title. The events "professor" and "instructor" are mutually exclusive. I'm leaving out the associate professors and assisant professors.
In total, there are 7+9+9+9 = 34 faculty members.
--------------
We found there are 16 faculty members who are either a professor or an instructor, out of 34 total members.
This must mean the probability we want is 16/34 = 8/17
Side note: 8/17 = 0.4706 = 47.06% approximately

Depreciation is the reduction in the value of an asset over time, due in particular to wear and tear.
What is depreciation?
Your information is incomplete. Therefore, an overview will be given. depreciation refers to an accounting method used to allocate the cost of a tangible or physical asset over its useful life.
To calculate depreciation, subtract the asset's salvage value from its cost. The result is the depreciable basis or the amount that can be depreciated. Divide this amount by the number of years in the asset's useful lifespan.

Tara just bought her first car in order to commute to college, a used 2014 Toyota RAV4! The value of the car today is $13,000, but will lose 11% of it’s value each year for the next several years. Down the road, Tara will trade the RAV4 in for a down payment on a newer car. If she trades in her car 4 years from now, how much will it be worth?
The future value after 4 years will be $8156.49 if the value of the car today is $13,000 but will lose 11% of its value each year for the next several years.
What is future value?Based on an estimated growth rate, the future value is the amount that an asset will be valued at a future date. The computation assumes that at the start date, a fixed amount of cash is made available for investment and that it increases at a constant rate until the selected future date.
We have:
Current value of the car = $13,000
Depreciation rate = 11%
Time n = 4 years
[tex]\rm Future \ value = (value \ at \ present) ( 1- \dfrac{depreciation \ rate}{100})^n[/tex]
[tex]\rm Future \ value = (13000)(1-\frac{11}{100} )^4[/tex]
Future value = $8156.49
Thus, the future value after 4 years will be $8156.49 if the value of the car today is $13,000 but will lose 11% of its value each year for the next several years.
