Answer:
[tex]a_n=-8+(n-1)-7[/tex]
Step-by-step explanation:
General arithmetic sequence formula: [tex]a_n=a_1+(n-1)d[/tex]
where [tex]a_1[/tex] = first term, and d = common difference.
The first term is -8
And the common difference appears to be - 7 as 7 is subtracted to get to the next term. Ex. -8 - 7 = -15, -15 - 7 = - 22 and so on.
To get the explicit formula of the sequence we simply plug in the values of a1 and d the general arithmetic sequence formula
General formula: [tex]a_n=a_1+(n-1)d[/tex]
We have [tex]a_1=-8[/tex] and d = -7
So the formula to find the nth term would be
[tex]a_n=-8+(n-1)-7[/tex]

6% OF 56% X 60% X 40%
Answer:
Step-by-step explanation:
6% of 56 is 10.71
6% of 60 is 10
6% of 15
hopefully this answers your question
6% of 56 is 10.71
6% of 60 is 10
6% of 15
After this, I think you may want to multiply 10.71, 10, and 15. Unless you were trying to separate all the numbers. If you weren't, its 1606.5!

2. Write and evaluate a subtraction expression to find the depth of the submersible at 2:17 p.m.
3. Write and evaluate a subtraction expression to find the depth of the submersible at 2:18 p.m.
4. If the submersible dove straight down, what is the distance between the submersible's starting position at 2:15 and its position at 2:18? Show your work.
Find the missing values in the ratio table. Then write the equivalent ratios. People 6 18 Benches 3 12 a The equivalent ratios are 6 : 3, : 12, and 18 : . Skip to navigation
The missing values in the ratio table are;
⇒ 6 : 3 , 24 : 12, and 18 : 9
What is mean by Ratio?
A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y.
Where, x and y are individual amount of two quantities.
And, Total quantity gives after combine as x + y.
Given that;
Peoples = 6 , 18
Benches = 3, 12
Now,
The equivalent ratios are;
⇒ 6 : 3 , x : 12 , 18 : y
Find the values of x and y as;
Since, All the ratio are equivalent.
So, we get;
⇒ 6 : 3 = x : 12
⇒ 6 / 3 = x / 12
⇒ 6 × 12 / 3 = x
⇒ x = 24
And, ⇒ 6 : 3 = 18 : y
⇒ 6 / 3 = 18 / y
⇒ 6 × y = 18 × 3
⇒ y = 18 × 3 / 6
⇒ y = 9
Thus, The missing values in the ratio table are;
⇒ 6 : 3 , 24 : 12, and 18 : 9
