Answer:
a₇ = 2.375
Step-by-step explanation:
There is a common ratio r between consecutive terms, that is
r =
=
=
= - 
This indicates the sequence is geometric with nth term
= a₁ 
where a₁ is the first term and r the common ratio
Here a₁ = 152 and r = -
, then
= 152
, so
a₇ = 152
= 152 ×
= 2.375
Answer:
7 pizzas and 9 cans of juice
Step-by-step explanation:
The answer is 7 pizzas because if you add the 25 people plus her parents (That would be two more people) is 27. Then you have to multiply 27×2 that would equal 54. So, now you know you need 54 slices but what you is the amount of pizzas needed. The next step would be to divide 54÷8 that would equal 6.75 but you can't buy 6.75 pizzas, and you can't buy 6 pizzas because than you would leave people outside. You will need to buy 7 pizzas. It is better to have left overs than leaving people outside.
For the amount of cans would be 9 because if you add again 25 people plus her parents it would be 27. Then you multiply 27×1 that is obviously 27. The next step would be to divide 27÷3 and it would equal 9. And that is how you get your answer.
Answer:
Number 6 is 1/6
Number 7 is 5/6
Number 8 is 3/6 or 1/2
Step-by-step explanation:
6.
chance of landing on a 2 because there are 6 sides and the probability is equal.
There is a 1/6 chance it will land on 1, 2, 3, 4, 5, and 6. So 1/6 is the answer.
7.
chance of not landing on 5. There are 5 "non-5" numbers. So 5/6 is the answer.
8. Let's see the odd numbers: 1, 2, 3, 4, 5, 6.
1, 3, and 5 are odd. So that's half of the numbers so the answer would be
or simplified to
.
First we want to find how much it costs for 1 stamp, so we do 8.28 divided by 18, which equals 0.46. Then, we multiply 0.46 and 12, which is 5.52. Therefore, it would cost $5.52 to buy 12 stamps.
