Find The Value of x to the nearest degree.
Answer:
Step-by-step explanation:
sin(x) = opposite over hypotenuse
= 3/(3sqrt(2))
= 1/sqrt(2)
= sqrt(2)/2
x = arcsin( sqrt(2)/2 )
= arcsin( sqrt(2)/2 )
= 45°

Asurveyor standing at anoties two objects B and C on the opposite side of canal.The object are 120 m apart.If the angle of sight b/n the object is 37degre how wide is the canale
Answer:
159.25 meters
Step-by-step explanation:
Using the solution diagram attached ;
From Trigonometric relation, the width, w of the canal can be obtained using :
Tanθ = opposite / Adjacent
Tan 37 = 120 / w
w * tan 37 = 120
w = 120 / tan 37
w = 159.24537 meters
Hence, width of canal is 159.25 meters

in one day a truck delivered 48 tonnes of sand to a building site. the first three loads measured 11.25 tonnes, 12.76 tonnes, and 12.82 tonnes. How much sand was in the fourth and final load?
Answer:
11.17 tonnes was in the fourth and final load.
Step-by-step explanation:
11.25 + 12.76 + 12.82 = 36.83 > total of the first 3 loads.
x = 4th load.
36.83 + x = 48
x = 48 - 36.83
x = 11.17

40% of students prefer to use pencils over pens for their assignments. What is the probability that you randomly select four students and all four prefer to use pencils over pens?
Answer:
0.0233
Step-by-step explanation:
We are told that 40% of students prefer to use pencils over pens for their assignments.
This means 40 out of 100 students prefer to use pencils over pens.
Thus, for the first draw, P(pencil over pens for first draw) = 40/100
Since person using pencil over pens is selected without replacement, then, we now have a sample space of 99;
Second draw; P(pencil over pens for 2nd draw) = 39/99
Similarly, for third draw; P(pencil over pens for 3rd draw) = 38/98
For fourth draw; P(pencil over pens for 4th draw) = 37/97
Thus;
probability that you randomly select four students and all four prefer to use pencils over pens is;
P(all four prefer pencils over pens) = (40/100) × (39/99) × (38/98) × (37/97) = 0.0233

What are Plane, Collinear points, and Intersecting lines?Generally, a Plane is simply defined as three noncollinear endpoints, two parallel lines,
If two or more points are located on the same straight line, they are said to be collinear.

Okey hey, hi, hello, all I want to know is how to put this dang thing on the number line but I have searched everywhere and no one can help me !!!!!!!!
Can you ?
Your graph would be correct if the given equation was |x| = 5
This is because |x| describes the distance x is from zero, and asking |x| = 5 means we want to find which values are 5 units away from zero: those two values being 5 and -5.
--------------
However, your teacher gave you instead |x| = -5. The distance cannot be negative, so |x| is never negative. Therefore, |x| = -5 has no solutions
The graph will simply be an empty number line with no points plotted on it.
Bryan’s monthly electric bill is determined by adding a flat administration fee to the product of the number of kilowatt hours of electricity used and the cost per kilowatt hour. When he uses 1,100 kilowatt hours of electricity, his bill is $113. When he uses 1,500 kilowatt hours of electricity, his bill is $153. What is the monthly administration fee?
We will form the equations for this problem:
(1) 1100*y + z = 113
(2) 1500*y + z = 153
z = ? Monthly administration fee is notated with z, and that is the this problem's question.
Number of kilowatt hours of electricity used are numbers 1100 and 1500 respectively.
Cost per kilowatt hour is notated with y, but its value is not asked in this math problem, but we can calculate it anyway.
The problem becomes two equations with two unknowns, it is a system, and can be solved with method of replacement:
(1) 1100*y + z = 113
(2) 1500*y + z = 153
----------------------------
(1) z = 113 - 1100*y [insert value of z (right side) into (2) equation instead of z]:
(2) 1500*y + (113 - 1100*y) = 153
-------------------------------------------------
(1) z = 113 - 1100*y
(2) 1500*y + 113 - 1100*y = 153
------------------------------------------------
(1) z = 113 - 1100*y
(2) 400*y + 113 = 153
------------------------------------------------
(1) z = 113 - 1100*y
(2) 400*y = 153 - 113
------------------------------------------------
(1) z = 113 - 1100*y
(2) 400*y = 40
------------------------------------------------
(1) z = 113 - 1100*y
(2) y = 40/400
------------------------------------------------
(1) z = 113 - 1100*y
(2) y = 1/10
------------------------------------------------
if we insert the obtained value of y into (1) equation, we get the value of z:
(1) z = 113 - 1100*(1/10)
(1) z = 113 - 110
(1) z = 3 dollars is the monthly fee.

x - 15 120 a a 12 c 33
y - 5 40 3 6 b a d
Answer:
x - 15 120 9 18 12 33
y - 5 40 3 6 4 11
Step-by-step explanation:
x - 15 120 a a 12 33
y - 5 40 3 6 b d
x = 3y
When y = 5
x = 3y
x = 3 * 5
x = 15
When y = 40
x = 3y
x = 3 * 40
x = 120
When y = 3
x = 3y
x = 3 * 3
x = 9
When y = 6
x = 3y
x = 3 * 6
x = 18
When x = 12
x = 3y
12 = 3y
y = 12/3
y = 4
When x = 33
x = 3y
33 = 3y
y = 33/3
y = 11

The domain of [tex]tanx[/tex] is [tex]R - (n\pi -\frac{\pi }{2})[/tex].
The range of the given function [tex]y = tanx[/tex] is the set of all real numbers.
What is domain?The domain of a function is the set of values that we are allowed to plug into our function.
What is range?The range of a function is the set of its possible output values.
According to the given question.
We have a function
[tex]y = tanx[/tex]
The above function can be written as
[tex]y = \frac{sinx}{cosx}[/tex]
⇒ [tex]tanx[/tex] is defined for all values except the values that makes [tex]cosx = 0[/tex], a fraction with denominator is not defined.
And we know that
[tex]cosx = 0 \ \forall \ x \in \frac{(2n+1)\pi }{2} \ where \ n \in Z[/tex]
Hence, for all these values, [tex]tanx[/tex] is not defined.
Therefore, the domain of [tex]tanx[/tex] is [tex]R - (n\pi -\frac{\pi }{2})[/tex].
Since, the domain of [tex]tanx[/tex] is [tex]R - (n\pi -\frac{\pi }{2})[/tex], so when we input these values in the given function we get only real numbers.
Therefore, the range of the given function [tex]y = tanx[/tex] is the set of all real numbers.
Thus, option D and B are correct.

Erin calculated the average speed of her most recent run to be 120/16 miles per hour how is this friction expressed as a decimal
Answer:
[tex]\dfrac{15}{2}[/tex]
Step-by-step explanation:
The average speed of the Erin is 120/16 mph
Here,
Numerator = 120
Denominator = 16
mph = miles per hour
We need to find an expression expressed as a decimal.
So,
[tex]\dfrac{120}{16}=\dfrac{2\times 3\times 2\times 2\times 5}{2\times 2\times 2\times 2}\\\\=\dfrac{15}{2}[/tex]
So, the final answer is [tex]\dfrac{15}{2}[/tex].
