A protected wilderness area in the shape of a rectangle is 3 kilometers long and 3.2 kilometers wide. The forest is to be surrou nded by a hiking trail that will cost $11 comma 000 per mile to construct. What will it cost to install the trail? Note that 1 mile (mi)almost equals1.6 kilometers (km).
1 answer:
Answer: $66
Step-by-step explanation:
Area of a rectangular =length*breadth
= 3.2 km * 3.0 km = 9.6km(squared)
Note, 1.6km = 1 mile
Cost of a hiking trail = $11 per mile
Converting kilometer to kill = 9.6km/1.6km = 6 miles
Hence, cost of a hiking trail to surround the rectangular shaped wilderness = $11 * 6 = $66
In case the cost is $11,000 per mile; total cost of hiking trails to surround the wilderness equals $66,000

<h3>Given</h3>
m∠REG = 78° mAR = 46° ER ≅ GA <h3>Solution</h3>
m∠GAR = 180° - m∠REG = 180° - 78° = 102° (supplementary angles sum to 180°) m∠TAR = 1/2mAR = 1/2(46°) = 23° (tangent chord angle is half the size of intercepted arc) m∠GAN = 180° - (m∠TAR + m∠GAR) = 180° - (23° + 102°) = 55° (straight angle is 180°) mAG = 2m∠GAN = 2(55°) = 110° mRE = mAG = 110° (as ER ≅ GA) mGE = 360° - (mAG + mAR + mRE) = 360° - (110° + 46° + 110°) = 94° (full circle is 360°)
Answer:
VW = 7
Step-by-step explanation:
Because it is a parallelogram, UX = VW
x-4 = 2x - 15
11 = x
VW = 2 x 11 - 15
VW = 7
Answer:
7
Step-by-step explanation:
Fiction books: (1/6) of 30 books = 5 books
Non-fiction books: (3/5) of (30) books = 18 books
The subtotal here is 5 + 18, or 23.
23 of the books are either fiction or non fiction.
30 - 23, or 7, of the books remain (are neither fiction nor non-fiction).
