Answer: Choice A) 15 feet
=====================================
x = length of fourth side in quadrilateral ABCD
Have a look at the attached image I've posted. I made a chart that lines up the side lengths from largest to smallest. Note how the first two items in the bottom row are blank. We don't know these values and we don't need to find out in order to find x.
Based on the last two columns of that table, we can form the proportion below, which is then used to isolate x.
30/12 = x/6
30*6 = 12*x ... cross multiply
180 = 12*x
12*x = 180
x = 180/12 ... divide both sides by 12
x = 15
Answer:
135
Step-by-step explanation:
subtract 180 by 45 since a line is 180, that is what you get for the angle that is adjacent to angle 2, there is a rule if it is adjacent, they equal each other. thus, angle 2 is 135
Answer:
385 golf balls
Step-by-step explanation:
margin of error = (z*)(s) / sqrt n
where z* = 1.96 with 5%/ 2 = 0.025 area in each tail
margin of error = (z*)(s) / sqrt n
1.2 yards = (1.96)(12 yards) / sqrt n
solve for n
n = 384.16
385 golf balls (always round up)
16 3/4 + 12 3/4
16 +12 = 28
3/4 +3/4 = 1 1/2
28 + 1 1/2 = 29 1/2 hours total
The height of Mount Kilimanjaro is 19,340 feet.
To convert to scientific notation move the decimal point so there is only 1 digit to the left of the decimal pint, you then multiply that by 10 raised to the number of spaces you moved the decimal point.
19,340 - Move the decimal point 4 places to the left to get 1.9340
You can remove the 0 at the end to get 1.934
You moved the decimal 4 places so raise 10 to 4 and get the final answer:
1.934 x 10^4
The first choice is the correct one.
