Answer:
D
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin30° = 
, then
sin30° = 
= 
= ( cross- multiply )
f = 24
----------------------------------------------------------------
Using the cosine ratio and the exact value
cos30° = 
, then
cos30° = 
= 
= 
= ( cross- multiply )
2e = 24
( divide both sides by 2 )
e = 12
"Dimensional analysis" is the primary way to make conversions between any units. Some have trouble because they fail to make it an important point to label units, but labeling units correctly makes tracking and making any conversion very simple...The process and thinking is that you want to cancel out units that you don't need in the solutions...
(198ft/s)(12in/ft)(2.54cm/in)(m/100cm)=60.3504m/s (and that is exact)
d=5s(60.3504m/s)=301.752m
ugh...assume that a meter equals 3.3 feet and do not round your answers???
really? These people are idiots when there is an exact conversion. What is the point of not rounding when you are using a horrible approximation? :D
(198ft/s)(m/3.3ft)=60m/s
d=5s(60m/s)=300m
Answer:
radiation
Step-by-step explanation:
The energy budget of the Earth is dominated by radiation from the Sun. Without it, there would be no life on Earth.
Radiation is also an important contributor to night-day temperature differences and the weather they cause.
Answer:its actually 124
Step-by-step explanation:
Hi. Are you sure you are evaluating and not simplifying? Typically when you evaluate, a number is given for each variable.
If you are simplifying it is broken down as follows:
3y + 6/2x
= 6xy + 6/2x
= 3xy + 3/x
I hope this helps a little.
Take care,
Diana
