Convert the following angle from degrees to radians. Express your answer in simplestform.285°
Answers
Answer:
19π/12
Explanation:
We know that
180 degrees = π radians
and we are asked
285 degrees = ? radians?
This can be treated as a ratio problem by saying that
[tex]\frac{180}{\pi}=\frac{285}{x}[/tex]where x is the angle in radians.
Cross multpication gives
[tex]180x=285\pi[/tex]dividing both sides by 180 gives
[tex]x=\frac{285\pi}{180}[/tex][tex]x=\frac{19}{12}\pi[/tex]where we have used the fact that 285/12 = 19/12.
4.97 radians (or 5 radians if rounding)
Explanation:
The formula for converting degrees to pi is (a) x pi/180
Plugging in 285 it becomes
285 x pi/180 =
And when we use a calculator to find it you will get 4.97 or 5 radians

Given that Sarah spent half of her weekly allowance.
She earns $4.70 for washing dogs.
The final amount is $ 13.50.
Let x be the weekly allowance.
She spent half of her allowance so she has half of the allowance.
[tex]\frac{x}{2}[/tex]She earns $ 4.70, add this to her half of the allowance.
[tex]\frac{x}{2}+4.70[/tex]This is equal to 13.50.
[tex]\frac{x}{2}+4.70=13.50[/tex]Subtracting 4.70 from both sides, we get

9x-3x=7+9
-What i basically did was i passed the 3x from the right side to the left side of the equation, since in adding the 3x originaly, when i pass it to the left side itll be subtracting. then i passed my -9 to the right side of my equation, since i was subtracting originaly ill have to now switch it to adding
-after you do this you are going to want to want to combine like terms
6x=16
-then you are going to want to devide on both sides so you can get x alone

The first aircraft has 65 more seats than the second aircraft. The third aircraft has 41 fewer seat than the second aircraft. If their total number of seats is 402, find the number of seats for each aircraft.
Answers
Solution:
Let A be the first aircraft
Let B be the second aircraft
Let C be the third aircraft
Here is the information that is given in the question:
The first aircraft has 65 more seats than the second aircraft:
A = B + 65
The third aircraft has 41 fewer seats than the second aircraft
C = B - 41
their total number of seats is 402
A + B + C = 402
Now substitute the values in the 1st and 2nd equations into the 3rd.
(B+65) + B + (B-41) = 402
this is equivalent to:
3B + (65-41) = 402
this is equivalent to:
3B + 24 = 402
this is equivalent to:
3B = 402 - 24 = 378
solving for B, we get:
[tex]B\text{ = }\frac{378}{3}=126[/tex]We can conclude that the correct answer is:
first aircraft A:
A = B + 65 = 126 + 65 = 191
that is:
A = 191
second aircraft:
B = 126
third aircraft:
C = B - 41 = 126 - 41 = 85
that is:
C = 85

What is the most precise name for quadrilateral ABCD with verticesA(-5, 7), B(6,-3), C(10, 2), and D(-1, 12)?A. rectangleB. rhombusC. squareD. parallelogram
Answers
Given that
The vertices of a quadrilateral are A(-5, 7), B(6,-3), C(10, 2), and D(-1, 12).
So we have to find the type of quadrilateral ABCD.
Explanation -
First, we have to find the length of each side AB, BC, CD, and DA.
We will use the distance formula to find the length of each side
[tex]\begin{gathered} T\text{he distance formula for point \lparen x}_1,y_1)\text{ and \lparen x}_2,y_2)\text{ is } \\ d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \end{gathered}[/tex]Now we will find the sides by substituting the value,
[tex]\begin{gathered} For\text{ AB,} \\ AB=\sqrt{(6-(-5))^2+(-3-7)^2} \\ \\ AB=\sqrt{(6+5)^2+(-10)^2}=\sqrt{11^2+10^2}=\sqrt{121+100}=\sqrt{221} \\ \\ AB=\sqrt{221}\text{ units} \end{gathered}[/tex][tex]\begin{gathered} For\text{ BC,} \\ BC=\sqrt{(10-6)^2+(2-(-3))^2} \\ BC=\sqrt{4^2+(2+3)^2} \\ BC=\sqrt{16+25}=\sqrt{41} \\ BC=\sqrt{41}\text{ }units \end{gathered}[/tex][tex]\begin{gathered} For\text{ CD} \\ CD=\sqrt{(-1-10)\placeholder{⬚}^2+(12-2)\placeholder{⬚}^2} \\ CD=\sqrt{(-11)^2+(10)^2} \\ CD=\sqrt{121+100} \\ CD=\sqrt{221}\text{ units} \end{gathered}[/tex][tex]\begin{gathered} For\text{ DA,} \\ DA=\sqrt{(-1-(-5))^2+(12-7)^2} \\ DA=\sqrt{(-1+5)^2+5^2} \\ DA=\sqrt{4^2+5^2}=\sqrt{16+25} \\ DA=\sqrt{41}\text{ units} \end{gathered}[/tex]So we found that the opposite sides are equal. So it can be a parallelogram or a rectangle.
Now, we will check the triangular part ABC, by applying Pythagoras' theorem.
[tex]\begin{gathered} In\text{ trianlge ABC, } \\ AC=\sqrt{(10-(-5))^2+(2-7)^2}=\sqrt{(10+5)^2+(-5)^2} \\ AC=\sqrt{15^2+5^2} \\ AC=\sqrt{225+25}=\sqrt{250} \\ Now\text{ using pythagoras theorem we have,} \\ AC^2=AB^2+BC^2 \\ \sqrt{250}^2=\sqrt{221}^2+\sqrt{41}^2 \\ 250=221+41 \\ 250\ne262 \end{gathered}[/tex]So it is a parallelogram. Then option D is correct.
Final answer -
The final answer is a parallelogram.which statement is true of this function f x equals 1/5 - 2

9(x+2/6)^2=-8
therefore
step 2 is not validHow many pounds of N are in 2 tons of manure (4.8% N)?
Answers
Answer: 192 lbs
Total weight of manure = 2 tons
Step1: we need to converts tons to pounds
1 ton = 2000 lb
2 tons = x lb
Cross multiply
2 x 2000 = 1 * x
x = 2 x 2000
x = 4000 lbs
Therefore, 2 ton of manure = 4000 lbs of manure
We have 4.8% of N in the manure
Pounds of N = 4.8/100 x 4000
Pounds of N = 0.048 x 4000
Pounds of N = 192 lbs
The pounds of N in 2 tons of manure is 192 lbs
Which of the following statements is true about the graph shown?
The equation y = 4.5x is correctly represented by the graph.
The graph is incorrect and the line should go through the point (3, 13.5).
The graph is incorrect and the line should go through the point (4.5, 4.5).
The graph does not show a proportional relationship.
Answers
Answer:
B. The graph is incorrect and the line should go through the point (3, 13.5)
Step-by-step explanation:
The equation is y = 4.5x
y = the y-axis/dependent variable
x = the x-axis/independent variable
4.5 x 1 = 4.5
4.5 x 2 = 9
4.5 x 3 = 13.5
Therefore the written ordered pairs would look like this.
(1, 4.5)
(2, 9)
(3, 13.5)
In the graph, (3, 13.5) is graphed as (13.5, 3) making the graph incorrect.
The statement which is true about the graph shown is that: the graph is incorrect and the line should go through the point (3, 13.5).
How to interpret the graph?Generally speaking, the graph of any linear function is always modeled by a straight line and it indicates a proportional relationship because it starts from the origin (0, 0).
Mathematically, a proportional relationship can be represented or modeled by the following linear equation:
y = kx
Where:
k represents the constant of proportionality.x and y represents the data points, variables, or coordinates.At data point (4.5, 4.5), we have:
y = 4.5x
y = 4.5(4.5)
y = 20.25 (incorrect).
At data point (3, 13.5), we have:
y = 4.5x
y = 4.5(3)
y = 13.35 (correct).
Therefore, we can logically deduce that this graph is incorrect because its line didn't pass through the data point (3, 13.5).

Answers
The unit rate for calories per cup is 100 calories per cup.
There is 400 calories in 4 cup of cereal.
Given,
The amount of calories in 3/4 of the cup = 75 calories
We have to find the unit rate of calories per cup.That is,
Unit rate of calories = 75 / (3/4)
Unit rate of calories = 75 × (4/3)
Unit rate of calories = 25 × 4
Unit rate of calories = 100
There are 100 calories in a cup of cereals.
Now,
We have to find the calories in 4 cup of cereals.Calories in 4 cup = Calories in one cup × 4
Calories in 4 cup = 100 × 4

Answers
For the given system of equations 4x + 6y=24 and 2x + 3y=8, there is no solution exists.
What is defined as the system of equations?When two or more equations are solved together in algebra, the solution should satisfy all of the equations with in system. The amount of equations must equal the amount of unknowns for a system to produce a unique solution. Even so, no solution is guaranteed. If there is a solution, the system has been consistent; otherwise, it is inconsistent.For the given system of equation,
4x + 6y =24 ......eq 1
and 2x + 3y = 8 ..... eq2
use elimination method.
Multiply eq 2 with 2 and subtract from eq 1.
0 = 16
But 0 ≠ 16, the system of equation becomes untrue.
As, the values o f the variables x and y are getting cancelled. So, the there is no solution existed for the given system.
Also,the ratio of 4x/2x = 2 and 6y/3y = 2 is same thus, no solution is possible for the system.
Now, when the we triple each side of the first equation 4x+6y=24, we have 12x+18y=72.
The new system 12x+18y=72 and 2x+3y=8
Then, also 12x/2x = 6 and 18y/3y = 6 is also same. Then, also the system of equation does not have any solution of the system.
