Answer:
See below in bold.
Step-by-step explanation:
(1) cosec ( x + 10) = 3
Now cosec x = 1/sin x so
1 / sin (x + 10) = 3
3 sin (x + 10) = 1
sin (x + 10) = 1/3
x + 10 = 19.47 , 160.53 degrees
x = 9.47, 150.53 degrees.
(ii) cot (x - 30) =0.45
cot (x - 30)= 1 /tan (x- 30) so we have
tan (x - 30) = 1 / 0.45 = 2.2222
x - 30 = 65.77 degrees
x = 95.77 degrees.
A. $6800 + $1360= $8160 total cost
b.
$68.85 each * 165 bracelets = $11360.25
$11360.25- $8160 total cost = $11278.75 profit
$11278.75 profit/$8160 total cost= 1.38218
1.38218= about 138%
Final answer: 138%
Warning: This answer will vary if you find the percent over cost (not including duty).
Answer:
Biological weathering is the actual molecular breakdown of minerals. There are things called lichens (combinations of fungi and algae) which live on rocks. Lichens slowly eat away at the surface of rocks. The amount of biological activity that breaks down minerals depends on how much life is in that area
Step-by-step explanation:
Answer:
5,000
Step-by-step explanation:
Just round up the 5, but the digit in the hundreds place is a 9, which rounds up to 10, so changes the number to 5000.
