Answer:
$2076.30
Step-by-step explanation:
In the n-th year, the rent will be ...
an = a1·r^(n-1) . . . . . . . . . r is the year on year ratio: 1+rate of increase
an = 1100·(1.095^(n-1))
Then the rent in the 8th year is ...
a8 = 1100·(1.095^(8-1)) ≈ 2076.30
The rent in the 8th year would be $2076.30.
Answer:
The sum of ages of all 18 pupils in the class = 81
Step-by-step explanation:
Total number of pupil in the class = 18
Average of years in the class =
Now,
⇒Average of sum of ages in the class = 4.05
Let us assume the sum of ages of all students in the class = m
By the formula for AVERAGE:
or, m = 18 x 4.5 = 81
Hence, the sum of ages of all 18 pupils in the class = 81
Answer:
1) 1500 meters.
2) 3600 meters.
Step-by-step explanation:
Firstly we need to find the value of angle x in the given figure attached to the answer and then use the trignometric identity to calculate the value for 1) and 2) part.
as we know that the triangle is a right angled triangle also second angle is given so we can find the value of the third triangle using the sum of all the angles of a triangle is 180°.
x+67.4°+90°=180°
x=22.6
1)
Now we know that:
Hence to the nearest meter the value of a will be: a=1500 meter.
Hence, When the probe reaches the ocean floor, the probe will be approximately 1500 meters below the surface, measured vertically from the surface
2)
We are asked to find the value of 'b'.
As
Hence to the nearest meter the value of b is 3600.
When the probe reaches the ocean floor, the horizontal distance of the probe from the team’s ship on the ocean surface will be approximately 3600 meters.
