Substitute in values
Hence, <em> is calculated to be 0.557</em>
Answer:
B
Step-by-step explanation:
a^2 + b^2 = C^2
solve for b
b^2 = c^2 - a^2
square root on both sides of the equation and you get option b as your answer
Answer:
B
Step-by-step explanation:
using the tangent ratio on the triangle on the right and the exact value
tan60° = 
, then letting the altitude be h
tan60° = 
= 
= ( multiply both sides by h )
11
= h × ( divide both sides by )
11
= h
using the sine ratio in the triangle on the left and the exact value
sin45° = 
, then
sin45° = 
= 
= 
= ( cross- multiply )
× x = 22 ( divide both sides by )
x = 22
Answer:
Option B.
Step-by-step explanation:
We need to express 505 kL in L.
Here, kL means kiloliter and L means liter.
We know that
1 kL = 1000 L
Using this conversion we can easily convert 505 kL in L.
Multiply both sides by 505.
505 × 1 kL = 505 × 1000 L
505 kL = 505,000 L
The value of 505 kL can be expressed as 505,000 L.
Therefore, the correct option is B.
