<h3><u>given</u><u>:</u></h3>
each interior angle= 168°
<h3><u>to</u><u> </u><u>find</u><u>:</u></h3>
the number of sides the polygon has.
<h3><u>solution</u><u>:</u></h3>
180- 360/n= 168
12= 360/n
n= 360/12
n= 30
<u>therefore</u><u>,</u><u> </u><u>the</u><u> </u><u>polygon</u><u> </u><u>has</u><u> </u><u>30</u><u> </u><u>sides</u><u>.</u>
Answer:
7.5 hours
Step-by-step explanation:
The key here is to find out how much can be done in the same amount ot time
the least common multiple of 5 hrs and 3 hrs is 15hrs
In 15 hours:
- At 5 hours per lawn Norton could mow 15/5 = 3 lawns
- At 3 hours per lawn together thay could mow 15/3 = 5 lawns
In 15 hours Jesse would mow 5 - 3 = 2 lawns
15 hours/ 2 lawns = 7.5 hours per lawn
7.5 hours
--------------------
Here's the math
1 lawn/5hrs + x = 1 lawn / 3hrs
1/5 + x = 1/3
Subtract 1/5 from both sides
x = 1/3 - 1/5
x = 5/15 - 3/15
x = 2/15
x = 2lawns/15 hrs
15hrs/2lawns = 7.5 hrs per lawn
7.5 hours

Answer:
5196 m
Step-by-step explanation:
The difference in elevation is found by subtracting one elevation from the other. Usually, we're interested in the positive difference, so we subtract the smaller number from the larger.
5040 -(-156) = 5040 +156 = 5196
The difference in elevation is 5196 meters.
The number of doctors that would be needed for the 35-bed wing is 38.
<h3>How many more doctors are needed?</h3>
The first step is to determine the number of doctors needed for one bed : 463 / 423
The second step is to multiply the ratio gotten in the first step by the number of beds in the new wing: (463 / 423) x 35 = 38.21 = 38
