Elza [17]

Answer:

Total length of string required in yards $8112$ yards

Step-by-step explanation:

The length of the string attached with each balloon is equal to $12$ feet

In the party total number of balloon used is equal to $52$ balloons

The total length of the string required

Length of string used in one balloon * total number of balloons

$= 12 * 52 = 624$ feet

1 feet is equal to 13 yards

Total length of string required in yards $13 * 624 = 8112$ yards

Janis used the sum of cubes formula to factor 27x^3+8 Her answer is (3x+2)(9x^2-6x+2^2) Identify her error if any.

kicyunya [14]

Answer:

According to the sum of cubes formula, Janis is correct

Step-by-step explanation:

The sum of cubes formula is given as follows;

x³ + y³ = (x + y)·(x² - x·y + y²)

The given expression is presented as follows;

27·x³ + 8

The given expression can be expressed as 27·x³ + 8 = (3·x)³ + 2³

Therefore, using the sum of cubes formula, we have;

(3·x)³ + 2³ = (3·x + 2)·((3·x)² - 3·x·2 + 2²) = (3·x + 2)·(9·x² - 6·x + 2²)

∴ 27·x³ + 8 = (3·x)³ + 2³ = (3·x + 2)·(9·x² - 6·x + 2²)

Therefore, Janis is correct, by the sum of cubes formula, we get;

27·x³ + 8 = (3·x + 2)·(9·x² - 6·x + 2²).

8.4.49 A cow is tethered to one corner of a square barn, 19 feet by 19 feet, with a rope 160 feet long. (See the illustration

SashulF [63]

Answer:

$20096 ft^2$

Step-by-step explanation:

We are given that

Length of rope=l=160 feet

Radius of quadrant of circle=r=160 feet

We have to find the maximum grazing area of the cow.

We know that

Area of quadrant of circle= $\frac{1}{4}\pi r^2$

Where $\pi=3.14$

Using the formula

Area grazed by cow= $\frac{1}{4}\times 3.14(160)^2$

Area grazed by cow= $20096 ft^2$
