Answer:

The area of the circular ring is 53.73 π  sq. yards

Step-by-step explanation:

The diameter of the skating ring = 44 ft

Diameter =  2 x Radius

⇒Radius of the ring  = 44 / 2  = 22 ft

Now, 1 ft = 0.333333 yards

⇒22 ft  = 22 x 0.333333 yards = 7.3333 yards

Now, Area of the circular Ring = \pi r^2\\

or, A = \pi (7.33)^2

=  53.73 π  sq. yards

or, the area of the circular ring is 53.73 π  sq. yards

Answer: 11 boxes of cards for $72

Step-by-step explanation:

Brennan's equation would be

y=6x+6

Gabriel's Equation would be

y=5x+17

when they spend the same amount the equations will be equal

6x+6=5x+17

x+6= 11

x=11

so 11 boxes they would spend the same

To figure out cost, put 11 into the first equations

y=6(11)+6= 66+6= 72

y=5(11)+17= 55+17 = 72

so they each spent $72

What is the product (3a2 b4) (- 8b3)
Anvisha [2.4K]

Answer:

-24 a^2 b^7

Step-by-step explanation:

Simplify the following:

-8×3 a^2 b^4 b^3

Hint: | Combine products of like terms.

3 a^2 b^4 (-8) b^3 = 3 a^2 b^(4 + 3) (-8):

-8×3 a^2 b^(4 + 3)

Hint: | Evaluate 4 + 3.

4 + 3 = 7:

-8×3 a^2 b^7

Hint: | Multiply 3 and -8 together.

3 (-8) = -24:

Answer: -24 a^2 b^7

2/3(x-2)=-2<br>how would I solve this ​
xeze [42]

Answer:

x =(5/3)

Step-by-step explanation:

The given expression is \frac{2}{3(x-2)}  = -2

Now to simplify it,

The first step is to cross multiply.

So, the expression becomes

\frac{2}{(-2)}  = 3(x-2)

or, -1  = 3x - 6

⇒  3x = -1 + 6

⇒ 3x = 5 , or x =(5/3)
