Answer:
Below in bold.
Step-by-step explanation:
speed = distance / time
2.4 * 10^4 = 3.2 * 10^6 /time
Time = 3.2 * 10^6 / 2.4 * 10^4
= 3.2/2.4 * 10^(6-4)
= 1.3333.. * 10^2 hours
= 133 hours ( to 3 significant figures).
How to do the problem:
Assuming that you mean you want 12% of the number 80 and showing work, here is the answer:
To get X percent of any number, write the percent as a decimal and then multiply that decimal by the whole.
What I mean:
You want 12% of 80
so first change 12% into a decimal
12% is equal to .12 as a decimal
Then multiply that decimal by the whole
Since you want 12% of 80, 80 is the whole
that means you do .12 * 80
which is equal to 9.6
<u>Thus(answer)</u>
12% of 80 = 9.6
Answer:
okay
Step-by-step explanation:
Answer:
It is a right angled triangle.
so
tan32 = p/b
or, tan32 = x/5
or, tan32×5 = x
so, x = 3.124
for 5 no. the answer is a. 3.124
For y,
cos32 = b/h
or, cos32 = 5/y
or, y = 5/cos32
so, y = 5.895
for 6 no. 5.895 is closest to 5.994, so the answer is c. 5.994.
