The angle turns through 1/12th of the circle what is the measure of the angle
Answer:
30°
Step-by-step explanation:
A full circle has 360°.
1/12 of a circle has 1/12 of 360°.
1/12 * 360° = 360°/12 = 30°
Answer: 30°
A piece of work takes 20 labourers to complete in 10 days. how many labourers will complete the same job in 25 days if they work at the same rate?
Step-by-step explanation:
If 20 labourers=10 days
x labourers = 25 days
10x= 25×20
[tex] \frac{10x}{10} = \frac{25 \times 20}{10}[/tex]
Cancelling out by 10 on both sides
[tex]x = \frac{25 \times 2}{1} \\ x = 50 [/tex]
Therefore, it takes 50 labourers to complete the work at the same rate in 25 days.

Give the slope of a line perpendicular to AB
Answer:
m = -1
Step-by-step explanation:
Find the equation in slope intercept form [ y = mx + b ] for line AB. Find the slope using the formula [ y2-y1/x2-x1 ].
8-5/7-4
3/3
1
Find the y-intercept.
5 = 1(4) + b
5 = 4 + b
1 = b
So the equation of the line AB is y = x + 1.
The slope of a perpendicular line is the opposite reciprocal of the original line.
1 -> -1/1 -> -1

At a pumpkin patch customers can purchase three types of tickets depending on
what they want to do. Ticket prices are $6 $10 and $12. Last weekend, 500 total
tickets were sold, and the total income from ticket sales were $4.500 How many $6
tickets were sold if the combined number of $6 and $10 tickets was four times the
number of $12 tickets sold
Answer: 175
Step-by-step explanation:
Let say
x the number of ticket at $6
y the number of ticket at $10
z the number of ticket at $12
500 total tickets were sold : x+y+z=500
the total income from ticket sales were $4.500: 6*x+10*y+12*z=4500
the combined number of $6 and $10 tickets was four times the
number of $12 tickets sold: x+y=4*z
x=175

50 points please help me
Answer:
0
Step-by-step explanation:
The slope of the line is 0 as it is parallel to x-axis.
Slope = (y2 - y1)/(x2 - x1)
= (2-2)/(4-(-2))
= 0
Answer:
Slope = 0
Step-by-step explanation:
Taking any two points.
(x1,y1) = (3,0)
(x2,y2) = (-1,0)
Now,
[tex]\displaystyle Slope = \frac{y_2-y_1}{x_2-x_1} \\\\Slope = \frac{0-0}{-1-3} \\\\Slope = \frac{0}{-4} \\\\Slope = 0\\\\\rule[225]{225}{2}[/tex]

a window is 9ft long. It is x feet longer than it is high. What is the height of the window.
The height of the window is 9-x feet.
Given that, a window is 9 ft long. It is x feet longer than it is high.
We need to find what is the height of the window.
What is an expression?An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.
Here, the length of the window = 9 ft
Then, the height of the window = x feet smaller than the length = 9-x feet
Therefore, the height of the window is 9-x feet.

Find 6 3/4 − 4 11/12. Write your answer in the simplest form.
A. 1 2/3
B. 1 5/6
C. 2 5/6
D. 3
ANSWER
First of all I turn the fractions back to their improper form that is to say;
6 3/4 - 4 11/12
= 27/4 - 59/12
after that I get the LCM of 12 and 4 which is 12
= (²⁷/⁴ × 12) - (⁵⁹/¹²× 12) /12
= (81 - 59) /12
= 22\12
since the answer is requested for in the simplest form the the difference in form of a mixed fration is 1 10/12 which is reduced to 1 5/6 therefore the answer is 'B'
