Answer:
3135
Step-by-step explanation:
Givens
a1 = 6
Use t4 - t3 to get d
t4 = 27
t3 = 20
Step One
Find a1 and d
a1 = 6
d = t4 - t3
d = 27 - 20
d = 7
Step Two
Find the 30th Term
tn= a1 + (n -1 )*d
t30 = 6 + (30 - 1) * 7
t30 = 6 + 29*7
t30 = 6 + 203
t30 = 209
Step Three
Find the sum using Sum = (a + t30)*n/2
n = 30 given
a1 = 6 given
t30 = 209 calculated from step 2
Sum = (a1 + t30)*n/2 Substitute
Sum = (6+ 209)*30/2 Combine like terms and divide by 2
sum = 215 * 15 Multiply
Sum = 3135 Answer
Answer:
if he sells 12 every 8 months, supposing the trend continues, in 34 months he’ll sell...
12(properties) = 8 months
12/8 = 1 month
1 month = 1.5(properties)
2 months = 3 properties
(since 1.5 properties is unrealistic, but it helps in the math, to find for one month)
so for 34 months he’ll sell...
1.5*34 = 51 properties
Answer:
Yes. They are equivalent.

Answer:
0.67 cm³
Step-by-step explanation:
<u>Volume = mass/density</u>
<u>Correct option</u>
8 would be B.
The ratio is 1:5, so the answer has to be a division of 5.
15*5 does not equal 90, but 18 does.
9 is correct.
