A rectangle has a width of 59 centimeters and a perimeter of 238 centimeters. What is the rectangle's length?

Mademuasel [1]

Answer:

60 cm

Step-by-step explanation:

2x the width and 2x the length gives you the perimeter. This can be represented by the equation:

2w + 2L = P

Use the information given in the word problem to fill in the variables.

2(59) + 2L = 238

118 + 2L = 238

move 118 to the other side of the equation.

2L = 238 - 118

2L = 120

move 2 to the other side of the equation.

L = $\frac{120}{2}$

L = 60

Student Practice: Follow the steps in the example.

Sergio039 [100]

Answer:

1) Option B - 25.12 ft

2) Option C - 24.1 ft

Step-by-step explanation:

1) Given : The circular rug has a diameter of 8.2 feet.

To find : Which measurement is closest to the circumference of the rug in feet?

Solution :

The circumference of rug is given by $C=\pi d$

Where, d is the diameter = 8.2 feet.

$C=3.14\times 8.2$

$C=25.748\ ft$

The most closest measurement is 25.12 ft.

Therefore, option B is correct.

2) Given : A circle has a diameter of 5.2 feet.

To find : Which measurement is closest to the circumference of the circle in feet?

Solution :

The circumference of circle is given by $C=\pi d$

Where, d is the diameter = 5.2 feet.

$C=3.14\times 5.2$

$C=16.328\ ft$

The most closest measurement is 24.1 ft.

Therefore, option C is correct.

Which choice is equivalent to the product below when x > 0?

anastassius [24]

The product below is equivalent when x > 0 is <u>1/9</u>

<h3>Resolution - Explanation</h3>

Square root is a real number x multiplied by itself - which results in a perfect value, where it is possible to calculate the real proof (which is the square root).

Given the expression, $\large \sf \sqrt{\dfrac{1}{x^{2} } } \cdot \sqrt{\dfrac{x^{2} }{81} }$ , first step: we will calculate the root of the numerator and denominator of this fraction:
