Answer: 0.7
Step-by-step explanation:
Let the number of white cows be x
Thus, the number of brown cows be (x+12)
Hence,
x+(x+12)=60
x+x+12=60
2x+12=60
2x+12-12=60-12
2x=48
Divide both parts of the equation by 2:
x=24 white cows
x+12=36 brown cows
The number of white cows are less than one year old:
The number of brown cows are less than one year old:
The total number of cows are less than one year old:
Thus
Fraction of all the cows are less than one year old:
Answer:
m∠°
Step-by-step explanation:
Complementary angles are a pair of angles whose measures have a sum of °. Since m∠
=
and m∠
=
, we can write the following equation to solve for
:
Solving for , we get:
(Simplify LHS)
(Subtract
from both sides of the equation to isolate
)
(Simplify)
(Divide both sides of the equation by
to get rid of
's coefficient)
Therefore, m∠°. Hope this helps!
Answer:
The height of the taller building is
Step-by-step explanation:
see the attached figure to better understand the problem
step 1
Find the value of h1
with the angle of elevation
we know that
step 2
Find the value of h2
with the angle of depression
we know that
step 3
Find the height of the taller building
The height of the taller building is the sum of h1 plus h2
so
