Which property is illustrated by the equation 3 (m n) = (3 m) n?
associative property
commutative property
distributive property
identity property

Answer:

x = 4

Step-by-step explanation:

[tex] In\: \triangle PQR, \: \angle PQR = 90\degree\: \&\: QS\perp PR [/tex]

Therefore, by geometric mean property:

[tex] QS^2 = PS \times SR[/tex]

[tex] 6^2 = 9 \times x[/tex]

[tex] 36 = 9 \times x[/tex]

[tex] \frac{36}{9}= x[/tex]

[tex] 4 = x[/tex]

Answer:

3.28 cm

Step-by-step explanation:

The calculation is given below:

we assume the following things

R denotes the radius of the circle

And, A denotes An arc  

Now , the length of the arc is  

L = (A ÷ 360°) × 2 × 3.14 × R

According to the question

R = 6 cm

Angle = 5 minutes and 15 seconds

The clock could complete its revolution in 60 minutes  

Therefore  

60 minutes = 360°

Also

1 min = 60 seconds

So  

1 seconds =  1min ÷ 60seconds  

Now for 15 seconds it is

= 15 seconds × (1 ÷ 60)

= (15 ÷ 60) min

= 0.25 min

 And for 5 minutes and 15 seconds, it is  

= 5 min + 0.25 min

= 5.25 min

Also

60 minutes = 360°

So,  

1 minute = 360° ÷ 60min

Now For  5.25min

= (5.25min) × (360° ÷ 60min)

= 31.5°

Finally the length would be    

L = (31.5° ÷ 360°) × 2 × 3.14 × 6cm

= 3.28 cm

Answer:

Answer:

8.5

Step-by-step explanation:

The required value of the number is 8.5 which is twice the difference between a number and 5 is 7​.

To solve this problem, we first need to express the given information in terms of a mathematical equation.

The statement "Twice the difference of a number and 5 is 7" can be represented as the equation 2 × (x - 5) = 7, where x is the number we're trying to find.

Next, we can solve this equation to find the value of x. To do this, we can first distribute the 2 on the left-hand side of the equation to get 2x - 10 = 7.

Then, we can add 10 to both sides of the equation to get 2x = 17.

Finally, we can divide both sides of the equation by 2 to get x = 17/2 = 8.5.

Therefore, the required value of the number is 8.5.

Answer:

42.3

Step-by-step explanation:

3.6 × (3) + 4.5 × (7)

= 10.8 + 31.5

= 42.3

Answer:

351

Step-by-step explanation:

3.6 x 3 = 10.8                                3.6 x (3) + 4.5 x (7)

4.5 x 7 = 31.5                                       10.8 + 31.5

10.8 + 31.5 =  42.3                                  42.3

Answer:

z=(-3/2, -1/2) (Or z=(-1.5,-0.5) if they want decimals instead of fractions)

Step-by-step explanation:

7z²+8z+3-3z²=0

4z²+8z+3=0

(2z+3)(2z+1)=0

z=(-3/2, -1/2) (Or z=(-1.5,-0.5) if they want decimals instead of fractions)

Answer:

Step-by-step explanation:

7z^2 + 8z + 3 = 3z^2

4z^2 + 8z + 3 = 0

(2z + 3)(2z + 1) = 0

2z + 3 = 0

z = -3/2

2z + 1 = 0

z = -1/2

Step-by-step explanation:

Radius (r) = 7 feet

circumference (c) = ?

We know

C =2 πr

= 2 * 3.14 * 7

= 43.96 feet

Hope it will help :)

Answer:  43.96

==================================================

Work Shown:

C = 2*pi*r

C = 2*pi*7

C = 2*7*pi

C = 14pi ............. exact circumference in terms of pi

C = 14*3.14

C = 43.96

This value is approximate because pi = 3.14 is approximate.

Note: the circumference is the same as the perimeter of the circle. It's the distance around the circle's edge.

Answer:

77 degrees

Step-by-step explanation:

The interior angles of a triangle always add up to 180 degrees, so you can form an equation:

This is what i got. I'm not sure if im right tho

1) It's February and you go to the store to buy some food for your pets. You have a Great

Dane and a Savannah cat. The Dane eats 3 times as much as your cat so his food

cost $60 for the big bag and he eats that in one week. The Savannah cats food cost

$15 a bag and it lasts him one week as well. You are there to buy food for the month

and have no more than $300 total to spend. Can you afford a month's worth of food?

a) If you bought the cat 6 weeks worth of food, how many weeks worth can you

buy your Great Dane?
