Which of the following equations shows the commutative property of multiplication?
A.8x0=0
B.3 x 11 = 11 x 3
C.7 + 7 + 7 = 3 x 7
D.(4 x 2) x1 = 4 x (2 x 1)

Answer:250

Step-by-step explanation:

Answer:

60/1 or 60

Step-by-step explanation:

Divide 180 by 3

60

So the unit rate is 60/1

Answer:

60 miles per hour

Step-by-step explanation:

The unit rate is the number of miles traveled per hour.  To solve this divide the total miles traveled by number of hours, 180/3.  The quotient is 60.

Answer:B

Explanation Samuel earn per hour = 5 hrs

Commission = 65%

Samuel total earning for a day = 6 hrs

Now,

5(65)+6y

Answer:

1.25x

Step-by-step explanation:

Given that :

25% Increase in number of blog views can be expressed as (x + 0.25x)

Another way to make this representation is :

Total number of blog views + 25% of total

Total should add up to 100%

Let number of views = x

Hence,

(100% + 25%) of x

125% of x

125%x

= 1.25x

Answer:

C (the rate of change of f(x) is -1/2 and g(x) if 1/2

Step-by-step explanation:

i cant be 100% sure so take this with a grain of salt but if x was 1, f(x)'s rate of change (another word for slope) would be -1/2 whilst g(x)'s slope would be 1/2.

Answer:

The value if x is 20

Step-by-step explanation:

Hope this helps :)

The value of the variable x is 20. Then the correct option is A.

It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.

If the two chords of the circle intersect at a point, then the product of the segments of the chord will be equal.

We know that the product of (x - 5) & (x - 8) and (x - 5) & (x) will be equal. Then we have

(x - 5) · (x - 8) = (x - 11) · x

Simplify the equation, then the value of the  variable x will be

(x - 5) · (x - 8) = (x - 11) · x

x² - 13x + 40 = x² - 11x

2x = 40

x = 20

Thus, the value of the variable x is 20.

Then the correct option is A.

Answer:

A heptagon has 7 sides, so we take the hexagon's sum of the interior angles and add 180 to it getting us, 720+180= 900 degrees

Step-by-step explanation:

The formula for calculating the sum of the interior angles of a regular polygon is: (n-2) x 180 degrees. N is the number of sides

Answer:

option 2 is the best answer

Step-by-step explanation:

I actually couldn't tell you 100% how i got this answer, but i narrowed it down to option 2 and option 3 because those ones have the inequality sign facing the correct way, and then I solved the inequalities to see which one made more sense, and option 3 came out as negative and you can't have a negative cost on something, so option 2 is the best answer.

Answer:

8. 9.1

9. 12.2

Step-by-step explanation:

8. let x represent the missing side:

Using pythagoras theorem;

13.3² = x² + 9.7²

x² = 13.3² - 9.7²

x² = 82.8 taking the square root of both sides;

x = 9.1

9. let y represent the missing side:

Using pythagoras theorem;

y² = 10² + 7²

y² = 149 taking the square root of both sides;

y = 12.2

Answer:

=21x2−13x+8

Step-by-step explanation:

=3x(7x−4)+−1(x−8)

=3x(7x−4)+−1x+(−1)(−8)

=3x(7x−4)+−x+8

Distribute:

=(3x)(7x)+(3x)(−4)+−x+8

=21x2+−12x+−x+8

Combine Like Terms:

=21x2+−12x+−x+8

=(21x2)+(−12x+−x)+(8)

=21x2+−13x+8

Answer:

30

Step-by-step explanation:

since x=5, and it's 6x, it'd be the same as 5x6, or 6(5).

Answer:

I think it should equal 30

Step-by-step explanation:

If x is 5 it would be 6(5) so you multiply 6 and 5 which equals 30

(sorry if i'm wrong)

Answer:

∠2 and ∠5 should not be Alternate exterior angles. ∠2 and ∠11 can be Alternate exterior angles if that is an option. The rest is correct. As for consecutive interior angles, you have (∠3 and ∠9), (∠4 and ∠10), (∠7 and ∠13) and (∠8 and ∠14).

Step-by-step explanation:

Alternate exterior angles are basically like the angles that are the combination of a vertically opposite angle and a corresponding angle. Since the vertical lines are not parallel, ∠2 and ∠5 cannot be Alternate exterior angles.

Consecutive interior angles are any pair of angles that are within a pair of parallel lines and add up to 180°.

Hello! Lets take a look.

Answer:640^2

Step-by-step explanation:

The Pythagorean Theorem states that the sum of the squared sides of a right triangle equals the length of the hypotenuse squared. You might recognize this theorem in the form of the Pythagorean equation: a 2 + b 2 = c 2.

8cm^2+24cm^2=640^2

Answer:

0.2839

Step-by-step explanation:

Can you tell me what part you are stuck on?

Answer:

0.2839

Step-by-step explanation:

-First, move the decimal over 4 places to the right to make 0.0167 into a whole number, which will turn into 167.

-Now, multiply 17 times 167 to get 2839.

-Finally, since the decimal from 0.0167 was moved 4 places to the right, it needs to be moved back 4 places to the left. Once it was moved back 4 places to the left, the answer should now be 0.2839
