What is slope and intercept of the line 2x 3y 6?
Answers
The slope of linear eqution of two variables x and y, i.e., 2x+3y = 6 is -2/3 and intercept is 2 .
The slope-intercept form expression of a linear equation is y = mx + c --------->(1)
Where m --> slope of the straight line and
c --> the x - intercept .
The expression for slope is represented as :
m = (y₂ - y₁) / (x₂ - x₁) ------>(2)
where (x₁, y₁) and (x₂, y₂) are any two points lying on the straight line. Once the slope m is determined then the general equation of the straight line can be determined easily.
Now we have , the equation in the problem statement is 2x + 3y = 6. firstly , we can rewrite it in the slope-intercept form as :
3y = 6 - 2x
=> y = 6/3 - 2x/3
=> y = -2x/3 + 6/3
=> y = (-2/3)x + 2
comparing the above eqution with eqution(1) we get , m = -2/3 and c = 2. So, slope and intercept of eqution 2x + 3y = 6 are -2/3 and 2 respectively.

Why is the sine of an acute angle less than one?
Answers
The sine of an acute angle is less than one because it is defined as the ratio of the length of the side opposite the angle to the length of the hypotenuse in a right triangle. Since the side opposite the angle is shorter than the hypotenuse, the ratio is always less than one.
To what does sin equate?
In contrast to the cosine of an angle, which corresponds to the ratio of the nearby side to the hypotenuse, the sine of an angle is the ratio of the opposite side to the hypotenuse.
It's also the same reason why the cosine of an acute angle is always less than one because it is the ratio of the adjacent side of the angle to the hypotenuse.
It's important to note that this is only true for acute angles, angles smaller than 90 degrees.
For obtuse angles, greater than 90 degrees, the sine and cosine values are greater than one.

The following data were obtained in a study taken on a horizontal milling machine: Parts produced per cycle: 8. Average measured cycle time: 8.36 minutes. Average measured stress time per cycle: 4.62 minutes. Average fast traverse time: 0.08 minutes. Average cutting time with electrical power: 3.66 minutes. Performance rating: 115%. Clearance (machine time): 10%. Slack (effort time): 15%. The operator works on the task 8 hours a day and produces 380 parts. How many standard hours does the operator work
Answers
Answer:
8.04 ≈ 8 hours
Step-by-step explanation:
Given data:
parts produced per cycle = 8
Average measured cycle time = 8.36 minutes
Average measured stress time per cycle ( observed workers time) = 4.62 minutes
e.t.c
Determine the number of standard hours the operator works
Given that the operator works for 8 hours a day and produces 380 parts
First : calculate the normal time for worker and machine ( Normal time = ( observed worker time * performance rating ) / 100
Normal time for worker = (4.62* 115) / 100 = 5.31 mins
Normal time for machine = (observed cycle time - observed worker time ) = 8.36 - 4.62 = 3.74 mins
Next; determine the Total standard time for Machine and worker = ( normal time * ( 1 + Allowance factor )
Standard Time For Worker = 5.313* (1 + 0.1) = 5.84 mins
while Standard Time for Machine = 3.74 *( 1 + 0.15) = 4.30 mins
Total standard time = 5.84 + 4.3 = 10.14 mins
Finally determine the standard hours the operator works
Standard hours = (Standard Piece Time* Pieces produced) / 60
where ; Standard piece time = Standard time / pieces per cycle = 10.14 / 8 = 1.27 mins
hence ; Standard hours = ( 1.27 * 380 ) / 60 = 8.04 hours
A rectangle has a length of 4 millimeters and an area of square 116 millimeters. What is the width? What is the perimeter?
Answers
Answer:
Width = 29mmPerimeter = 66mmStep-by-step explanation:
The area of a rectangle can be calculated by the formula:
= Length * Width
As we have the length and the area, we can make the width the subject of the formula to solve for it:
116 = 4 * width
Width = 116/4
= 29 mm
Perimeter is:
= Length + Length + Width + Width
= 4 + 4 + 29 + 29
= 66 mm
Find the measure of angle A. (Hint: You will need to find the value of x, but that is NOT the solution.)
Answers
Answer:
41°
Step-by-step explanation:
Sum of angle measures in a triangle: 180°
So,
108 + x + 5 + x - 5 = 180
Simplify.
2x + 108 = 180
Subtract 108 from both sides.
2x = 72
x = 36
Substitute x = 36 into (x + 5)
m∠A = 36 + 5 = 41
Thus, the answer is 41°

In a certain lottery, 5 numbers between 1 and 13 inclusive are drawn. These are the winning numbers. How many different selections are possible

1287 combinations are a way to calculate the total outcomes of an event where order of the outcomes does not matter.
How many different lottery combinations are there?You win the jackpot if you match all six numbers. You receive a lesser fixed prize if you partially match some of the numbers.
Divide the number of winning lottery numbers by the total number of available lottery numbers to discover the probability of winning any lottery. Use the formula if the numbers are picked from a set and the order of the numbers is unimportant.
To find the winning combination we use the following formula
n !/ r!( n – r ) !
Where n = total number of to be drawn
r = the number which are drawn
In this question, n = 13, and r = 5
from the formula
13 !/5!( 13 – 5 ) !
= 13! / 5! 8!

A conical candle is to be made from 250 cm3 of wax. If the candle's height is three times its diameter, what radius and height should it have, to the nearest tenth?
Answers
Answer:
The radius and height of the cone are 3.41 cm and 20.46 cm respectively.
Step-by-step explanation:
Given that,
The volume of a conical candle is 250 cm³.
The height of candle is 3 times of its diameter.
h = 3d (d = 2r, radius)
So,
h = 6r
The formula of volume of a cone is given by :
[tex]V=\dfrac{1}{3}\pi r^2h\\\\250=\dfrac{1}{3}\pi \times r^2\times 6r\\\\250=2\pi r^3\\\\r=(\dfrac{250}{2\pi })^{1/3}\\\\r=3.41\ cm[/tex]
Height, h = 6r = 6(3.41) = 20.46 cm
Hence, the radius and height of the cone are 3.41 cm and 20.46 cm respectively.
