What is the equivalent of pi over 3 radians in degrees?
Answers
and pretty sure you know how much that is.
Answer: The equivalent expression in degrees is 60°.
Step-by-step explanation: We are given to find the equivalent of the following expression in degrees.
[tex]E=\dfrac{\pi}{3}~\textup{radians}.[/tex]
We will be using the UNITARY method the solve the given problem.
We know that
[tex]\pi~\textup{radians}=180^\circ\\\\\\\Rightarrow 1~\textup{radian}=\left(\dfrac{180}{\pi}\right)^\circ\\\\\\\Rightarrow \dfrac{\pi}{3}~\textup{radians}=\left(\dfrac{\pi}{3}\times\dfrac{180}{\pi}\right)^\circ=60^\circ.[/tex]
Thus, the equivalent expression in degrees is 60°.
What is the power of 10 when 0.000028 is written in scientific notation?
Answers
just count how many places you need to move the decimal to put it after the 2
Answer:
The power of 10 would be -5
Step-by-step explanation:
In scientific notation we write a very small or very large number as the product of a number from 0 to 9 and the exponent of 10,
For getting a number between 0 to 9 if the decimal shifted right side then the exponent of 10 is negative power of total shifting while if the decimal shifted left side then the exponent of 10 is positive power of total shifting.
Here, the number is,
0.000028
By the above explanation, we need to shift the decimal five time to the right so the exponent of 10 would be 5.
[tex]\implies 0.000028=2.8\times 10^{-5}[/tex]
A company employs 48 people in various departments. The average annual salary of each employee is $25,000 with a maximum variance of $3,000. What is the range of the total salary that the company pays to its employees annually?
Answers
n = 48, the sample size
m = $25,000, th sample mean
σ = $3000, the maximum variance
The standard deviation is
s = √σ = √(3000) = 54.772
As a rule of thumb, the range is 4 times the standard deviation. Therefore the range is
R = 4*54.772 = 219.09
Half the range is
R/2 = 219.09/2 = 109.45
The required range is
(25000-109.45, 25000+109.45) = (24890.46, 25109.54)

Final answer:
To determine how many minutes each boy plays in a 36-minute gym period with 24 boys wanting to play basketball, with only 10 able to play at a time, each boy would play for 15 minutes.
Explanation:
To find out how many minutes each boy plays in a 36-minute gym period with 24 boys and 10 playing at a time:
Calculate the total time for 24 boys: 24 boys / 10 boys playing at a time = 2.4 sets.

with that template in mind, let's see [tex]\bf f(x)=\sqrt{x}\qquad \begin{array}{llll} g(x)=&\sqrt{0.5x}\\ &\quad \uparrow \\ &\quad B \end{array}[/tex]
so B went form 1 on f(x), down to 0.5 or 1/2 on g(x)
B = 1/2, thus the graph is stretched by twice as much.
The transformation of the function f(x) to g(x) is a horizontal stretch.
Step-by-step explanation:The parent function f(x) is given by:
[tex]f(x)=\sqrt{x}[/tex]
and the transformed function g(x) is given by:
[tex]g(x)=\sqrt{0.5x}[/tex]
Now we know that the transformation of the type:
f(x) → f(bx)
is a horizontal stretch if 0<b<1
and is a horizontal shrink if b>1
Here we have:
[tex]b=\dfrac{1}{2}=0.5[/tex]
i.e.
[tex]0<b<1[/tex]
This means that the transformation of the function f(x) to g(x) is a horizontal stretch by a factor of 2.

Solve by the linear combination method (with or without multiplication). x + y = 40 0.08x + 0.03y = 1.7
Answers
x + y = 40
.08x+.03y=1.7
We need to multiply the top equation by either a -.08 or a -.03 to eliminate one of the variables. Let's get rid of the y:
-.03(x + y) = -.03(40) which gives us
-.03x - .03y = -1.2
.08x + .03y = 1.7
When we add those together we are left with .05x = .5 and x = 10. If we sub that 10 in for x into the first equation (either would have worked but the first one is way easier to work with!) we get 10 + y = 40 and y = 30. So the solution to the system is (10, 30)

What is perimeter of the triangle?The perimeter of a triangle is defined as the total length of its boundary.
The basic formula used to calculate the perimeter of a triangle is:
Perimeter = sum of the three sides
According to the question
The lengths of the sides of a triangle are in the extended ratio 1 : 2 : 5 .
Let common constant factor within ratio = x
Therefore,
Sides of triangle = x , 2x , 5x
and the perimeter of the triangle = 32 ft
i.e
according to the formula of perimeter of a triangle:
Perimeter = sum of the three sides
Now,
Substituting the value in formula
[tex]32 = x + 2x + 5x[/tex]
[tex]32 = 8x[/tex]
[tex]x = 4[/tex]
The sides of triangle is : 4 ft , 2*4 , 5*4

A company plans to sell a new type of vacuum cleaner for $280 each. The company’s financial planner estimates that the cost, y, of manufacturing the vacuum cleaners is a quadratic function with a y-intercept of 11,000 and a vertex of (500, 24,000). Which system of equations can be used to determine how many vacuums must be sold for the company to make a profit?
Answers
y = a(x - 500)² + 24000
Because the y-intercept is 11000, therefore
a(0 - 500)² + 24000 = 11000
a = (11000 - 24000)/500² = -0.052
The cost function is
y = -0.052*(x - 500)² + 24000
If x vacuums are sold at $280 per vacuum, then to make a profit requires that
280x ≥ y
or
280x ≥ -0.052(x-500)² + 24000
0.052(x - 500)² + 280x - 24000 ≥ 0

can someone explain the diffrence between first class, second class, and third class levers?
Answers
Final answer:
Levers are classified based on the positions of the fulcrum, input force, and output force. First-class levers have the fulcrum in the middle, second-class levers have the load in the middle, and third-class levers have the effort in the middle. The Mechanical Advantage of a lever indicates how much the lever amplifies the input force.
Explanation:
The three classes of levers are differentiated by the positions of the fulcrum, input force, and output force. A first-class lever has the fulcrum placed between the input force and the output force. Examples would include a seesaw and a crowbar. A second-class lever has the output force between the input force and the fulcrum, with examples being a wheelbarrow and a nutcracker. Lastly, a third-class lever has the input force between the output force and the fulcrum, as seen in a pair of tweezers or a human arm when lifting a weight.
The Mechanical Advantage (MA) is a calculation that shows how much a lever amplifies the input force. It is given by the ratio of the distance from the fulcrum to the input force (effort arm) and the distance from the fulcrum to the output force (resistance arm). Levers are simple machines that utilize torque and the physical distances from their pivot point to achieve an output force that is greater or faster or travels a further distance than the input force.
