The equation b=540−30m gives the balance b (in dollars) that you owe on a drum set after m monthly payments. What is the balance
2 answers:
Answer:
the balance after 9 monthly payments is, $270
Step-by-step explanation:
Given the equation:
....[1]
where,
b represents the balance in dollars that you owe on a drum set after m monthly payment.
We have to find the balance after 9 monthly payments
⇒ m = 9 months
Substitute the given values in [1] we have;
⇒
Therefore, the balance after 9 monthly payments is, $270

Observe the given figure.
Here, angle T and R are the inscribed angles.
And sum of inscribed angles is half of measure of intercepted arcs.
Since, the measure of intercepted arcs is 360 degrees.
Therefore,
Hence, the sum of the two angles is 180 degrees.
Therefore, these are the supplementary angles.
Therefore, angle T and angle R are supplementary angles.
Hence, proved.
The formula for an infinite geometric sequence is the following:
Just substitute the values of
and r into the formula.
Therefore, the answer is 20.
Just substitute the values of
Therefore, the answer is 20.
