Answer:
Hours driven= 40 hours
Step-by-step explanation:
Giving the following information:
Variable income= $21.6 per hour
Fixed income= $250
Total income= $1,114
<u>To calculate the number of hours driven, we need to use the following formula:</u>
Total income= fixed income + hourly rate*number of hours
1,114 = 250 + 21.6*x
864 = 21.6x
864 / 21.6 = x
40=x
Hours driven= 40 hours
I think we're not supposed to do more than 3 problems in one answer; certainly not five pages. Does the 1/3 mean there are 10 more to come?
I'll do the first page.
6)
Right triangle, opposite side of 10, adjacent side of 21,
tan x = opp/adj = 10/21
x = arctan 10/21 = 25.46°
Answer: 25
7)
cos x = adj / hyp = 10/14
x = arccos 10/14 = 44.42°
Answer: 44
8)
tan x = opp/adj = 12/24 = 1/2
x = arctan 1/2 = 26.57°
Answer: 27
9)
tan x = 31/32
x = arctan 31/32 = 44.09°
Answer: 44
10)
x = arctan 10/27 = 20.32°
Answer: 20
Answer:
$3.72
Step-by-step explanation:
Divide $2.79 by 3
$0.93 is the price of one orange
$0.93 times 4 is $3.72
Hope this helps!
If the half-life is t, then every t days, the amount of the radioactive isotope will be cut in half.
(1/2)^(number of half-lives) = 3%
number of half-lives = ln(0.03) / ln(0.5)
This gives the number of half-lives as 5.06.
Then 300 days = (5.06)(length of 1 half-life)
length of 1 half-life = 300 / 5.06 = 59.29 days
