Just plug in answers... its -12--2 which becomes -12+2 and you get
10
Hope this helps you!!!
1 in equals 25.4mm exactly so
.25in(25.4mm/in)=6.35mm
Answer:
A. +95
Step-by-step explanation:
- Above = positive
- So, 95 feet above sea level = +95
- Therefore, A is the correct option
I hope this helps!
We know that
in the triangle ROA
tan (∡ROA)=12/5
(∡ROA)=arc tan(12/5)---------> 67.38°
in the triangle OPA
(∡POA)=(∡ROA)-------> 67.38°
sin (∡POA)=PA/5-------> PA=5*sin (67.38°)-----> 4.62 units
the answer is
PA=4.62 units
<span>alternative method
</span>in the triangle ROA
RO²=12²+5²-------> RO=13 units
sin (∡ROA)=12/13
in the triangle OPA
(∡POA)=(∡ROA)
sin (∡POA)=12/13
sin (∡POA)=PA/5
12/13=PA/5-------> PA=12*5/13-------> PA=4.62 units
Answer:
12 meters
Step-by-step explanation:
The assumption regarding shadow lengths is that they are proportional to height at any given place and time.
__
Here, the streetlamp is 9/6 = 3/2 times as tall as the tree, so we expect its shadow to be 3/2 times the length of the tree's shadow.
(3/2)(8 m) = 12 m
The streetlamp's shadow is 12 meters long.
