Answer:
m∠1 is calculated as 49°.
Step-by-step explanation:
Consider the angles are the interior angles of a triangle.
m∠A =91°
m∠B = 40°
m∠1 = ?
We know that the sum of interior angles of a triangle is 180°. So,
m∠A + m∠B + m∠1 = 180°
or, m∠1 = 180°- m∠A - m∠B
or, m∠1 = 180°- 91° - 40°
or, m∠1 = 49°
Hence, m∠1 = 49°.
Answer:
15 and 5 hours.
Step-by-step explanation:
Call x the time taken by the first chap, and y the second.
Let's divide by 5 and play with the LHS of the first equation a bit:
we know how much x+y is ( first equation!) let's solve.
At this point it's easy to check that 
Answer:
Sequence One
Step-by-step explanation:
S = a₁ / (1 − r) is the infinite sum of a geometric series where |r| < 1.
Sequence One: r = 1/5
Sequence Two: r = 2
Sequence Three: not geometric
Sequence Four: r = -3/2
Only Sequence One has |r| < 1.
If the base were 1, then the final value would never change...it would be a constant...
If the base is between zero and one, it is an exponential decay equation, so the final value would continually get smaller and smaller...
