Find the sum of the arithmetic series given a1
12, d = 4, and n = 30.
A. 8434
B. 4200
C.4216
D. 2100
Answer:
D
Step-by-step explanation:
The sum to n terms of an arithmetic series is
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
Here a₁ = 12, d = 4 and n = 30 , then
[tex]S_{30}[/tex] = [tex]\frac{30}{2}[/tex] [ (2 × 12) + (29 × 4) ]
= 15(24 + 116)
= 15 × 140
= 2100 → D
The sum of the arithmetic series given a₁ =12, d = 4, and n = 30 is 2100, therefore the correct answer is D.
What is the Sum of arithmetic series?The sum of n terms of an arithmetic series can be easily found using a simple formula which says that, if we have an arithmetic series whose first term is a and the common difference is d, then the formula of the sum of n terms of the arithmetic series is as follows
Sn = n/2 [2a₁ + (n-1)d].
as given in the problem
a₁ =12, d = 4, and n = 30
Sn = 30/2 [2×12 + (30-1)×4]
= 2100
The sum of the arithmetic series given a₁ =12, d = 4, and n = 30 is 2100.

isabels class has collected 90 cans in a food drive they plan to sort the cans into n bags, with an equal number of cans in each bag. write an expression to show how many cans there will be in each bag.
Answer:
cn=90, so long as c and n are whole numbers
Step-by-step explanation:
There are two variables in this equation you have here. One, n the number of bags, has already been given to you, because there can be any number of bags. The other, weĺl call it c, is the number of cans in each bag. Because there could be any number of bags, and the number of cans needed in each one is also a variable, you are left with more than one option. Any solution will work so long as the number of cans, c, per bag, n, is equal to the total, 90. There could be 9 cans in 10 bags, or 10 cans in 9 bags, or 15 cans in 6 bags or vice versa. The only way to define it for one answer is to have a set number of bags or cans per bag. Hope this helps!

Answer:
D. [tex]-360\,\frac{km}{h}[/tex]
Step-by-step explanation:
Physically speaking, average acceleration ([tex]\bar a[/tex]), measured in kilometers per square hour, is defined by following formula:
[tex]\bar a = \frac{v_{f}-v_{o}}{t_{f}-t_{o}}[/tex] (1)
Where:
[tex]v_{o}[/tex], [tex]v_{f}[/tex] - Initial and final speed, measured in kilometers per hour.
[tex]t_{o}[/tex], [tex]t_{f}[/tex] - Initial and final instant, measured in hours.
The initial and final instants are, respectively:
[tex]t_{o} = 5\,min\times \frac{1\,h}{60\,min}[/tex]
[tex]t_{o} = 0.083\,h[/tex]
[tex]t_{f} = 9\,min \times \frac{1\,h}{60\,min}[/tex]
[tex]t_{f} = 0.15\,h[/tex]
If we know that [tex]t_{o} = 0.083\,h[/tex], [tex]v_{o} = 60\,\frac{km}{h}[/tex], [tex]t_{f} = 0.15\,h[/tex] and [tex]v_{f} = 36\,\frac{km}{h}[/tex], then the average acceleration of Kelly is:
[tex]\bar a = \frac{36\,\frac{km}{h}-60\,\frac{km}{h}}{0.15\,h-0.083\,h}[/tex]
[tex]\bar a = -358.209\,\frac{km}{h^{2}}[/tex]

If n + 7 = 10, evaluate 2n - 2
O 3
0 17
4
6
Answer:
The value of 2n - 2 is 4.
Step-by-step explanation:
Given the equation
[tex]n + 7 = 10[/tex]
Subtract 7 from both sides of the equation
[tex]n+7-7=10-7[/tex]
Simplify
[tex]n=3[/tex]
Now substituting n = 3 in the equation
2n - 2 = 2(3) - 2
= 6 - 2
= 4
Therefore, the value of 2n - 2 is 4.

Based on the amount invested and the amount it grew to, the simple interest rate is 1%.
Lauren invested $50 and got $50.50 after a year.
What is the Simple Interest rate?This rate can be found by the formula:
= (Difference in investment in year 1) / Amount invested x 100%
Solving gives:
= (50.50 - 50) / 50 x 100%
