Answer:
A) 7 + 4(n - 1)
Step-by-step explanation:
The explicit rule follows the form, Tn = a + (n - 1)*(d), where 'a' is the first term and 'd' is the common difference between the numbers
It says that the first term is 7, so 'a' is 7. It also says that the numbers go up by 4 (adding 4 to the previous number), hence 'd' is 4.
Sub these values into the equation:
Tn = 7 + (n - 1)*(4)
Same as: 7 + 4(n - 1)
Answer:
250 seconds
Step-by-step explanation:
You must divide how far the anchor must go (27.5 ft) by the speed it travels (0.07 feet per second). 27.5 / 0.07 = 250 seconds.
1. false
2. true
3. false
4. true
5.true
6.true
I'm not sure but, maybe if you divide 300000 by 5.5% and see what you get. Then times it by 6. Not sure if it's correct, maybe see someone else's answer?
Step-by-step explanation:
Given
[ 6 + ( 10- 8 ) *7 ] + 5
= [ 6 + 2 * 7] + 5
= [ 6 + 14 ] + 5
= 20 + 5
= 25
