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)

Determine three consecutive odd integers if the square of the largest integer is 33 less than the sum of the squares of the two smaller integers.

### Answers

Three consecutive odd integers

n, n + 2, and n + 4

(n + 4)2 = n2 + (n + 2)2 - 345

n2 + 8n + 16 = n2 + n2 + 4n + 4 - 345

n2 + 8n +16 = 2n2 + 4n - 341

0 = n2 - 4n - 357

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

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.

**Step-by-step explanation:**

2a). Volume of the cylinder = 308 cm³

Radius of the base of the cylinder = 7 cm

Formula to get the volume of a cylinder = πr²h

308 = π(7)²h

h = [tex]\frac{308}{49\pi }[/tex]

h = 2 cm

Therefore, height of the cylinder will be 2 cm.

2b). Formula to calculate the surface area of the cylinder = [tex]2\pi r(r + h)[/tex]

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.
