Calculator
4 miles in 1 hour.
1 mile will be covered in (1/4) hour.
22 miles will then be covered in: 22 * 1/4 = 11/2 = 5.5
22 miles will be covered in 5.5 hours.
Answer:
The percentage increase in bird population in the second years is 4% .
Step-by-step explanation:
Given as :
During two years, the population of birds of an island became 7 times more than before.
The the percentage increase in first year = =
=40%
Let The percentage increase in second year =
= r%
So, According to question
The initial population of bird = x
The increase population of bird =7 times before = 7 x
Now,
The increase population of bird = initial population of bird × (1+
) × (1+
)
Or, 7 x = x × (1+
) × (1+
)
Or,
= 1.4 × (1+
)
Or, 7 = 1.4 × (1+
)
Or,
= (1+
)
Or, 5 = (1+
)
Or, (1+
) = 5
Or,
= 5 - 1
Or,
= 4
∴ r = 4 × 100
I.e r = 400
so, The percentage increase = r% = 4
Hence The percentage increase in bird population in the second years is 4% . Answer
Answer:

Step-by-step explanation:
Given:
The function
passes through the point
.
For function
to transform to
, the graph has to translate 2 units to left.
Therefore, the point
will have to move 2 units to left.
Moving 2 units left means the
value of the point has to reduce by 2 units.
The
value of the point
is 2.
So, new
value after translation will be
.
Therefore, the graph of
must pass through
.
Answer:
76, 76 104
Step-by-step explanation:
Angle 3 is vertical so it is congruent to Angle 2.
Angle 6 is corresponding, so it is congruent to Angle 2.
Angle 8 is linear to Angle 6, so they add to 180
