Given:
The scale is 1:250.
To find:
The measurements in metres if 40 mm is drown on the plan.
Solution:
The scale is 1:250. It means,
1 mm of the drawing = 250 mm of original length
40 mm of the drawing = 40×250 mm of original length
40 mm of the drawing = 10000 mm of original length
We know that,
1000 mm = 1 m
1 mm = 0.001 m
10000 mm = 10000×0.001 m
10000 mm = 10 m
Therefore, the measurement is 10 metres if 40 mm is drown on the plan.
How do I find the volume of a solid by rotating the region bounded by the given curves about a specified line?
Step-by-step explanation:
if a region is bounded by two curves y=f(x) and y=g(x) on an internal a,b where 0<g(x)< f(x) then the volume of the solid obtained by the rotating region about the Y-axis is expressed by the integral of the difference of two functions: v= 2πbfax(x)jdx

I NEED HELP ASAPPPPPP!!!
Answer:
57 - 25y
Step-by-step explanation:
when 15 was distributed it should be '45 - 15y' instead of '45 + 15y'
An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
The correct expression is
12 + 15(3 - y) - 10y
12 + 15 x 3 - 15y - 10y
12 + 45 - 15y - 10y
57 - 20y
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Step 1:
12 + 15(3 - y) - 10y
Step 2:
12 + 15 x 3 - 15y - 10y
Step 3:
12 + 45 - 15y - 10y
Step 4:
57 - 20y
Now,
We see that,
There was an error in step 2 where instead of -15y, +15y was written.
Thus,
The correct expression is
12 + 15(3 - y) - 10y
12 + 15 x 3 - 15y - 10y
12 + 45 - 15y - 10y
57 - 20y

Jimmy stopped in Yewton for 45 minutes if Jimmy cycled at a steady speed of 24 km/h and his average speed for the whole journey, including the stops, was 18 km/h.
What is the distance?Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.
It is given that:
At 12:45 Jimmy left his home in Pinetrees and cycled to visit his grandmother in Oakville.
Let x be the total time Jimmy stops in Yewton:
Total time for the journey = 220 minutes (12:45 to 16:25)
As we know:
distance = speed×time
24(220 - 10 - x) = 18(220)
220 - 10 - x = 165
x = 210 - 165
x = 45 minutes
Thus, Jimmy stop in Yewton for 45 minutes if Jimmy cycled at a steady speed of 24 km/h and his average speed for the whole journey, including the stops, was 18 km/h.

Which pair of values could NOT be the roots of a quadratic polynomial?
A) 4 and 6
B) 5 and 5
C) 2 + 3i and 2 + 3i
D) 1 + 3i and 1 –3i
Answer:
Part c
Step-by-step explanation:
In quadratic equations of real coefficients, the complex roots always occur in conjugate bases. It means, if, 2 + 3i is one of the roots and then the second root must be 2 - 3i.
The pair of values that can not be the roots of a quadratic polynomial is 2 + 3i and 2 + 3i
A polynomial is an expression consisting of the operations of addition, subtraction, multiplication of variables.
Polynomials can be classified based on degree as linear, quadratic, cubic, etc.
