What is the cumulative property of multiplication?
The commutative property is a mathematical concept that states that the order in which we multiply the factors does not affect the product.
According to the commutative property, a mathematical principle, the product is unaffected by the order in which we multiply the integers.
According to the above, the example of a commutative property is:
11 x w x 3 = 11 x 3 x w
This expression is the one with the commutative property because it has the same factors on both sides of the equation in a different order and that does not affect the result.
Therefore, the correct answer is A.
This question is incomplete because you are missing the options, here are the options:
A. 11 x w x 3 = 11 x 3 x w
B. 11 x w x 3 = 11 x w x 3
C. (11 x w) x 3 = 11 x (w x 3)
D. 11 x (w x 3) = (11 x w) + (11 x 3)

Han wants to convert his Canadian dollars to euros for his trip to France. He has 427 Canadian dollars. the current exchange rate is 1.28 Canadian dollars per euro. how many euros will he have.
Answers
Answer:
He will have 334 Euros
Step-by-step explanation:
Hello.
Here is a currency conversion problem.
The man in this question seeks to convert his Canadian dollars to Euro as he is in France for a trip.
The exchange rate is given as;
1.28 canadian dollar = 1 euro
He has 427 CAD , and we want to know the amount in euro.
let the equivalent amount in Euro be x
Thus;
if
1.28 CAD = 1 EUR
427 CAD = X EUR
By cross multiplying, we have
1.28 * x = 427 * 1
x = 427/1.28
x = 333.59 Euros which is approximately 334 Euros
Solve 5n + 6 = -3n - 10
Answers
Hi there! :)
Answer:
[tex]\huge\boxed{n = -2}[/tex]
5n + 6 = -3n - 10
Solve for n:
Add 3n to both sides:
5n + 3n + 6 = -3n + 3n - 10
8n + 6 = -10
Subtract 6 from both sides:
8n + 6 - 6 = -10 - 6
8n = -16
Divide both sides by 8:
8n/8 = -16/8
n = -2.

This diagram is a straightedge and compass construction. A is the center of one circle, and B
is the center of the other. Select all the true statements.
a. AC = BC
b. AC = BD
C. CD = AB
d. ABCD is a square
e. ABD is an equilateral triangle
f. CD = AB + AB
Answers
Answer:
Correct choices are a, b, e
Step-by-step explanation:
As per diagram, the circles are equal.
Since the distance AB is the radius of both circles:
AB = AC = BC = BD = AD = r
So the answer choices:
a. AC = BC
Correct, both equal to r
b. AC = BD
Correct, both equal to r
C. CD = AB
Incorrect. Half of CD is the leg of 30-60-90 triangle and is equal to r√3/2, so CD = AB√3
d. ABCD is a square
Incorrect. ACBD is rhombus
e. ABD is an equilateral triangle
Correct, all three sides are equal to r
f. CD = AB + AB
Incorrect as CD = AB√3
A man drives from home at 10.45 to the airport which is 325 km away.He travels at an average speed of 50km/h. a) Find his arrival time at the airport. b)After sending of his friend,the man drives back at 18 35 and arrives home at 23 10. Write down the time taken for the return journey.
Answers
☸ Solution:
We have,
Departing time = 10 : 45 hoursDistance between home and airport = 325 kmAverage speed = 50 km/h
Finding time taken by the man,
⇛ Average speed = Total Distance/Total time
⇛ Total time = Total Distance/Average speed[tex].[/tex]
⇛ Total time = 325 km/50 km/h
⇛ Total time = 6.5 h (6 hrs 30 mins)
(a) Total Time duration,
⇛ Total Time = Reaching Time - Departing time
⇛ 6.5 h = Reaching Time - 10 : 45 hours
⇛ Reaching Time = 17 : 15 hours ( 5 : 15 pm)
(b) Finding time taken in return,
Departing time = 18 : 35 hoursReaching time = 23 : 10 hours
Total time duration,
⇛ Total Time = Reaching Time - Departing time
⇛ Total Time = 23 : 10 hours - 18 : 35 hours
⇛ Total Time = 22 : 70 hours - 18 : 35 hours
⇛ Total time = 4 : 35 hours

While making desserts for Fun Day, Methuki used 5/6 of a scoop of brown sugar as well as 1/2 of a scoop of white sugar. How much more brown sugar did she use?
Answers
Hey there! I'm happy to help!
We want to find how much more 5/6 is than 1/2. To do this, we simply subtract 1/2 from 5/6. This will show us how much more 5/6 is.
First, we multiply 1/2 by 3/3 so that the denominator is 6.
1/2×3/3=3/6
Now, we subtract this from 5/6.
5/6-3/6=2/6
We can simplify this to 1/3.
Therefore, Methuki used 1/3 scoop more of brown sugar than white sugar while making desserts for Fun Day.

Formula to get the volume of a cylinder = πr²h
308 = π(7)²h
h = [tex]\frac{308}{49\pi }[/tex]
h = 2 cm

Find the measure of APBˆ. A. 130 B. 63 C. 50 D. 230
Answers
Answer:
65
Step-by-step explanation:
TAB is an isosceles triangle by the point to tangent theorem theorem.
BAT and BAT are congruent because of the isosceles triangle definition.
CAT and ABT are right angles by the tangent theorem.
Thus, CAB and CBA are both 90 - 65 = 25.
ACB is 130 because triangles' angles add up to 180.
APB is one half of ACB by the inscribed angles theorem.
The measure of the arc APB will be 230°. Then the correct option is D.
What is a circle?
It is the circle of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.
We know that the tangents are equal.
Then triangle ΔATB is an isosceles triangle.
Then the angle ∠TAB and angle ∠TBA are congruent.
We know that the angle sum of a triangle is 180°.
∠TAB + ∠TBA + ∠ATB = 180°
65° + 65° + z = 180°
z = 50°
We know that the radius and tangent of circle make 90°.
And the angle sum of quadrilateral is 360°.
∠TAC + ∠TBC + ∠ATB + ∠ACB = 360°
90° + 90° + 50° + y = 180°
y = 130°
Then the measure of the arc APB will be
x = 360° – 130°
x = 230°
The measure of the arc APB will be 230°.
Then the correct option is D.
