hope this helps!

Look for a pattern and complete the conjecture.
denis-greek [22]

Answer:

390

Step-by-step explanation:

The formula of sum of arithmetic sequence is \frac{n}{2} (a+Tn)

The number of this series are 2, 4, 6, 8, 10, 12, .  .  .  .  , 60.

The first term ( a ) = 2

The 30th even number is 60

The Tn is the term of the sequence

So the equation is

30/2 x ( 2 + T_{30})

T_{30} = 60

30/2 x ( 2 + 60 )

30/2 x (62)

1860/2

klemol [59]

Answer:

Step-by-step explanation:

1a. 25/50 =x/100                

25*100= 2500/50= 50

A= 50%

1b. 35/40 = x/100

35*100= 3500/40= 87.5

A=87.5%

2a. 15/20= x/100

20*5= 100; 15*5= 75

A=75%

2b. 25/70= x/100

25*100= 2500/70= 35.71

A=35.71

3a. 15/80= x/100

15*100= 1500/80=18.75

A=18.75%

3b. 30/60= x/100

30/60= 1/2;1/2=0.5;0.5= 50%

A=50%

4a. 70/80 =x/100

70*100=7000/80 =87.5

A=87.5

4b.30/60 = 50% ( same as question #3b)
