Answer:
HI ≈ 12.22
Step-by-step explanation:
tan I = GH / HI
tan 42° = 11 / HI = 0.90
HI = 11/0.90 = 12.22

Answer:
179/495
Step-by-step explanation:
When the repeating decimal starts at the decimal point, the repeating digits can be turned into a fraction by putting them over the same number of 9s. That is, 0.61616161... is equivalent to 61/99.
Here, the repeating part is 1/10 that value, so is 61/990. This is added to the non-repeating part, which is 0.3 = 3/10.
Then the entire decimal is ...
0.361_61 = 3/10 + 61/990 = (297 +61)/990 = 358/990 = 179/495

Step-by-step explanation:
The area of a shape is the amount of space a shape can occupy, while the perimeter is the sum of its lengths.
- <em>The perimeter is </em>
<em>units</em> - <em>The area of the sanctuary is 27 square units</em>
We have:

<u>Perimeter</u>
See attachment for the layout of the sanctuary



From the attachment, the sides are
<em>AB, BF, FC, CD, DE and EA</em>
Start by calculating the length of each side using the following distance formula:

So, we have:






So, the perimeter (P) is:



<em>Hence, the perimeter is </em>
<em>units</em>
<u />
<u>Area</u>
To calculate the area, we need to divide the sanctuary into three.
- <em>Triangle ABF</em>
- <em>Triangle EFA</em>
- <em>Trapezium CDEF</em>
The area of ABF is:

Where:




The area of EFA is:

Where:


So:


The area of CDEF is:

Where



So, we have:



So, the area of the sanctuary is:




<em>Hence, the area of the sanctuary is 27 square units</em>

Based on the fact that Tess's score was 25 in the statistics exam as shown by the stem-and-leaf plot, her Tess's percentile was 30th.
<h3>What was Tess's percentile?</h3>
Tess's percentile depends on the number of people whose scores she is above.
When looking at the stem-and-leaf plot, we see that Tess's score of 25 is the 13th score.
Her percentile is therefore:
= (13 - 1) / 40
= 12 / 40
= 30th percentile
Rest of the question is:
Tess’s score was 25. What was her percentile?
