Answer:
2,400 meters
Step-by-step explanation:
4 × 60 sec = 240 meters a minutes
240 meters × 10 minutes = 2,400 meters in 10 minutes
Answer:
30
Step-by-step explanation:
Given:
Brian Height = 6 feet
Brian Shadow Height = 4 foot
Flag Shadow Height = 20 foot
Flag Height = Unknown ??
So we can use cross multiplication
6/4 = x/20
6×20/4 = x
6×20 =120
120÷4 = 30
So x= 30, which is the Flag Height

The sequence is converges and the limit is 
Step-by-step explanation:
In the geometric sequence
- The sequence is converges if IrI < 1, where r is the constant ratio between each two consecutive terms
- The sequence is diverges if IrI > 1
IrI < 1 means → -1 < r < 1
IrI > 1 means → r < -1 and r > 1
∵ The sequence is 60 , -10 ,
,
, .....
∵
, where
is the first term and
is the second term
∵
= 60
∵
= -10
∴
= 
∴ The constant ratio is 
∵ -1 <
< 1
∴ I
I < 1
∴ The sequence is converges
∵ The limit is the sum to infinity
∵ 
∵ a = 60 and r = 
- Substitute these values in the rule above
∴ 
∴ 
The sequence is converges and the limit is
