Answer:

1

Step-by-step explanation:

\bigg(3 {w}^{4}  {z}^{3} m \bigg) ^{0}  \\  =  {3}^{0}  \times {w}^{4 \times 0}  \times  {z}^{3 \times 0}  \times  {m}^{0}  \\ =  {3}^{0}  \times {w}^{0}  \times  {z}^{0}  \times  {m}^{0}  \\  = 1 \times 1 \times 1 \times 1.. ( \because {a}^{0 }  = 1) \\  = 1 \\  \therefore \:  \bigg(3 {w}^{4}  {z}^{3} m \bigg) ^{0}  = 1

Answer:

1

Step-by-step explanation:

whenever we have 0 in the exponent the term becomes equal to 1

(3w^4z^3m)^0

multiplying 0 with all terms inside the bracket

3^0 × w^4×0 × z^3×0 × m^1×0

solving the powers

3^0 × w^0 × z^0 × m^0

since we have 0 in the exponent so all the terms will become 1

1 × 1 × 1 × 1 = 1

The area of a rectangular wall of a barn is 85 square feet. Its length is 12 feet longer than the width. Find the length and wid
MaRussiya [10]

Answer:

Length = 17 feet, Width = 5 feet

Step-by-step explanation:

Given:

The area of a rectangular wall of a barn is 85 square feet.

Its length is 12 feet longer than the width.

Question asked:

Find the length and width of the wall of the barn.

Solution:

Let width of a rectangular wall of a barn = x

<u>As length is 12 feet longer than the width.</u>

Length of a rectangular wall of a barn = 12+x

As we know:

Area\ of\ rectangle=length\times breadth

85=(12+x)x\\\\85=12x+x^{2} \\

Subtracting both sides by 85

x^{2} +12x-85=0\\x^{2} +17x-5x-85=0\\Taking\ common\\x+(x+17)-5x(x+17)=0\\(x+17)(x-5)=0\\x+17=0, x-5=0\\x=-17,x=5

As width can never be in negative, hence  width of a rectangular wall of a barn = x = 5 feet

Length of a rectangular wall of a barn = 12+x=12+5=17\ feet

Therefore, length and width of the wall of the barn is 17 feet and 5 feet respectively.

.The price of a MP3 Player decreases from $382 to $261.50.find the percentage decrease in its price
FinnZ [79.3K]

The percent of change = ((new value - old value) / old value) × 100%

Our new value = $261.50

Our old value = $382

Plug our values into the equation above.

(($261.50 - $382) / $382) × 100% = -31.54%

A 15 ft. Ladder is placed against a building so that the distance from the top of the ladder to the ground is 10 ft. Find the di
kipiarov [429]

Answer:

  11.2 ft

Step-by-step explanation:

Assuming the building meets the ground at right angles, the right triangle formed has side length 10 ft and hypotenuse 15 ft. Then the other side length (d) is given by the Pythagorean theorem as ...

  d² + 10² = 15²

  d² = 225 -100 = 125

  d = √125 = 5√5 ≈ 11.2 . . . feet

The bottom of the ladder is about 11.2 feet from the building
