Answer:
The value of a[tex]_{12}[/tex] is 42
Step-by-step explanation:
The explicit formula of the arithmetic sequence is a[tex]_{n}[/tex] = a + (n - 1)d, where
a is the first termd is the common differencen is the position of the term in the sequence∵ a[tex]_{1}[/tex] = 20 ⇒ first term
∴ a = 20
∵ d = 2 ⇒ common difference
∵ We need to find a[tex]_{12}[/tex]
∴ n = 12
→ Substitute them in the formula above
∵ a[tex]_{12}[/tex] = 20 + (12 - 1)(2)
∴ a[tex]_{12}[/tex] = 20 + (11)(2)
∴ a[tex]_{12}[/tex] = 20 + 22
∴ a[tex]_{12}[/tex] = 42
∴ The value of a[tex]_{12}[/tex] is 42

Answer:
I believe the answer is C. 1,131 miles
Step-by-step explanation:
When we use a right triangle to solve, we already know the angles on the right triangle must be 45 45 90, since all triangles equal 180. Then using tan45 times 800 we get the side between Houston and Lincoln which is also 800. Pythag then solves 800²+800²=c²
c²=1280000 so √1280000 =1131
The answer is C.)
The side of Lincoln to Tallahassee is the largest. The distance between Houston and Tallahassee is smaller, meaning that it is accurately a larger number. It would be simple to understand that the base and height of the triangle could NOT add up to 1,600 because they would both have to be at least HALF the length of the distance between Tallahassee but they are not. Meaning the answer is 1,321
Hope this helps,

Daniel can spend no more than $40 at the fair. If admission into the fair is $10 and the rides cost $1.50 each, which inequality represents the greatest number of rides Daniel can go on?
A. 10r + 1.50 ≥ 40 B. 1.50r + 10 ≤ 40 C. 1.50r + 10 <40 D 10r+1.50<40
Explain your reasoning and solve the inequality :
Answer:The answer is B.
Step-by-step explanation: He has to spend 10 dollars to get into the fair and each ride cost 1.50. We don’t know how many rides he’s going to get on so that is an unknown variable multiplied by 1.50 (r). He also has to spend less than or equal to $40. So Daniel’s total of 1.50r + 10 has to be less than or equal to $40.

Lucy has 68 books.
This number of books is 70% more than the number of books she had last year.
How many books did Lucy have last year?
Answer:
Lucy had 40 books last year.
Step-by-step explanation:
assuming 100% is the percent;
100% + 70%
100 : x
170 : 68
cross multiply = 170x = 100 x 68
-------- ————-
170 170
cancel 170/170
therefore x = 100 x 68 divided by 170
result is 40
The number of books that Lucy has last year will be 40 books.
What is the percentage?The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
Lucy has 68 books. This number of books is 70% more than the number of books she had last year.
Let 'n' be the number of books. Then the equation is given as,
1.7 n = 68
n = 68 / 1.70
n = 40
The number of books that Lucy has last year will be 40 books.

What is the equation shown in the graph? Explain your answer.
Answer:
y=x
Step-by-step explanation:
The graph is going 1 up and 1 to the right. You can plug in a value for x and get y. So if you plug in 1 for x, you get 1 for y and if u plug in 2 for x, you get 2 for y, so when you graph (1, 1) and (2, 2) you know the graph is y=x.
