Y W P 8 cm E R WERP is a square. Find.

BlackZzzverrR [31]

1) All interior angles of a square are right angles, so angle WER measures 90°

2) All squares are parallelograms, and diagonals of a parallelogram bisect each other, meaning PA=AE=8 cm. Thus, PE=16 cm

3) All squares are rectangles, and diagonals of a rectangle are congruent, meaning WR=16 cm. Then, using the fact that the diagonals bisect each other, we get that WA=8 cm

4) If we consider right triangle WPR, we know it is isoceles because all sides of a square are congruent. So, the length of WP is:

$\frac{16}{ \sqrt{2} } = 8 \sqrt{2}$

Hence the correct final answer is:

$\frac{4y^3}{x^3}$

Further explanation:

Given

$Line\ 1: \frac{4}{1}.\frac{x^{-2}}{1}.\frac{1}{x}.\frac{y}{1}.\frac{1}{y^{-2}}$

The student made the mistake in line two. There was no need to move 4 in the first term, from numerator to denominator

The correct line 2 will be:

$Line\ 2: \frac{4}{1}.\frac{1}{x^2}.\frac{1}{x}.\frac{y}{1}.\frac{y^{2}}{1}}\\Line\ 3: \frac{4y^3}{x^3}$

Hence the correct final answer is:

$\frac{4y^3}{x^3}$

The Tortoise and the Hare is a fable about a race with the

viktelen [127]

a.i) The number of inches per minute that the Galapagos tortoise walks are <u>216 inches</u> (6 x 36).

a.ii) The time it would take a Galapagos tortoise to walk across the U.S. in hours is <u>2,933 hours</u> (1,056,000/(6 x 60).

b.i) The Hare runs <u>31,680 inches per minute</u> (1,900,800/60).

b.ii) The time it would take the Hare to complete the race across the U.S. in hours is <u>20 hours</u> (600/30).

c.) For the Tortoise to pass the Hare, the Hare needs to sleep for <u>2,913 hours</u> (2,933 - 20) or <u>121.4 days</u> (2,933/24).

<h3>What are the equivalent values for calculating distance?</h3>

In this exercise, the following equivalent values are used for computing the distance and speed:

1 mile = 1,760 yards
1 yard = 36 inches
1 hour = 60 minutes
Distance from Galapagos to the U.S. = 600 miles
600 miles = 1,056,000 yards (600 x 1,760).

<h3>Data and Calculations:</h3>

Speed of Galapagos Tortoise per minute = 6 yards/ min (60 yards in 10 minutes)

Speed of Hare = 30mph

30 miles = 52,800 yards (30 x 1,760)

52,800 yards = 1,900,800 inches (52,800 x 36)

= 880 yards per minute (52,800/60)
