Answer: 45
Step-by-step explanation:
f(n) = f(1)+CD(n-1)
f(n) = 12+3(n-1)
f(n) = 12 +3n -3
f(n) = 3n+9
plug in 12 for n
f(12) = 3(12)+9
= 36 +9

Raju and Ann saved a total of $1560. After Raju gave Ann $50, Raju had 5 times as much money as Ann. How much did Raju have at first?
Step-by-step explanation:
let amt of money Raju has be r and Ann be a.
a + r = 1560
a = 1560 - r --(1)
r - 50 = 5(a + 50)
r = 5a + 300 --(2)
sub (1) into (2):
r = 5(1560 - r) + 300
r = 8100 - 5r
6r = 8100
r = 1350
therefore he has $1350 at first.

What is an expression?An expression is a sentence with a minimum of two numbers or variables and at least one math operation such as addition, subtraction, multiplication, or division.
We have,
Let the amount of money Raju = R
Let the amount of money Ann = A
Now,
Raju and Ann saved a total of $1560.
This statement can be written as:
R + A = 1560 ____(1)
After Raju gave Ann $50, Raju had 5 times as much money as Ann.
This statement can be written as:
R - 50 = 5 ( A + 50 )
R - 50 = 5A + 250
R - 5A = 250 + 50
R - 5A = 300 _____(2)
From (1)
R = 1560 - A _____(3)
Putting (3) in (2),
1560 - A - 5A = 300
1560 - 6A = 300
1560 - 300 = 6A
1360 = 6A
A = 1260 / 6
A = 210
Putting A = 210 in (3) we get,
R = 1560 - A
R = 1560 - 210
R = 1350
Thus the amount of money Ann has at first is $1350.

A 48 ft rope is cut into 5 pieces according to the
ratio 2:2:3:4:5. What is the length. In feet, of the
longest piece?
A. 3
B. 6
C. 9
D. 15
please Answer ASAP
Answer:I think it d
Step-by-step explanation:
The length of the longest piece will be 15 ft.
We have a 48 ft rope is cut into 5 pieces according to the ratio →
2 : 2 : 3 : 4 : 5.
We have to determine the length in feet of the longest piece.
A rope of length 'y' ft is cut in the ratio 2:5. What is the length of smallest piece?Now -
2x + 5x = y
x = [tex]$\frac{y}{7}[/tex]
Smallest piece is of length → 2x → [tex]$\frac{2y}{7}[/tex]
According to the question, we have -
Length of rope = 48 ft
Ratio in which they are cut = 2 : 2 : 3 : 4 : 5.
Therefore -
2x + 2x + 3x + 4x + 5x = 48
16x = 48
x = 3
Length of the longest piece = 5x = 5 x 3 = 15ft
Hence, the length of the longest piece will be 15 ft.

Step-by-step explanation:
A basketball player scored 26 points in one game. In basketball, some baskets are worth 3 points, some are worth 2 points, and free-throws are worth 1 point. He scored four more 2-point baskets than he did 3-point baskets. The number of free-throws equaled the sum of the number of 2-point and 3-point shots made. How many free-throws, 2-point shots, and 3-point shots did he make?
Answer:
3 points = 2
2 points = 6
1 point = 8
Step-by-step explanation:
Given that:
Total point scored = 26
Let number of 3 point basket = x
Number of 2 point basket = x + 4
Number of free throws = x + x + 4 = 2x + 4
Hence,
Total 3 points = 3x
Total 2 points 2(x + 4)
Total free throw points = 2x + 4
3x + 2(x + 4) + 2x + 4 = 26
3x + 2x + 8 + 2x + 4 = 26
7x + 12 = 26
7x = 26 - 12
7x = 14
x = 2
Number of 3 points = x = 2
2 points = (x+4) = 2+4 = 6
1 point = (2x+ 4) = 2(2) + 4 = 8
The number of free-throws, 2-point shots, and 3-point sho ts he made are;
free-throws = 8
2 points = 6
3 points = 2
Let the number of 3 points basket be x
He scored four more 2-point baskets than he did 3-point baskets. Thus;
y = x + 4
number of free-throws equaled the sum of the number of 2-point and 3-point sho ts made. Thus;
z = x + x + 4
z = 2x + 4
Thus;
Total 3 points = 3x
Total 2 points = 2(x + 4)
Total fr ee points = 2x + 4
Since he scored a total of 26 points, then;

A hotel has a budget of $16,000 to buy 84 new mattresses. Each mattress costs $209. The hotel manager says, “Since 80 × $200 = $16,000, I can stay within the budget.”
Answer:
The hotel manager under-estimated. Without estimation, the exact price would be $17,556.
Step-by-step explanation:
He should've over-estimated the money to $210, and the mattresses to 90. So 210 × 90 is $18,900. So even if he did underestimate or overestimate, he still would not have been able to afford the mattresses.
