Answer: 1/21
Step-by-step explanation:
total = 2 + 1 +4 = 7
1/7 x 2/(7-1) = 2/42
2/42 simplifies to 1/21
1/7: 1 doughnut out of a total of 7 items
2/(7-1): 2 mint cookies are available in the pool out of 6 items -> since one item has already been chosen without replacement, so now the total is 6.
An arithmetic sequence is given below.

Write an explicit formula for the n^th term a(n).
help me understand this plzz, no file just answer
Answer:
a(n)= a + (n - 1)d
a(n) = 17 - 3n
Step-by-step explanation:
14, 11, 8 , 5 , ...
The given sequence above is an Arithmetic sequence and the explicit formula is given as:
a(n) = a + (n - 1)d
Where
a = First term = 14
n = number of terms
d = common difference
The common difference =
Second term - First term or Third term - Second term
= 11 - 14 or 8 - 11 or 5 - 8
= -3
Therefore, the explicit formula for the nth term a(n) is written as:
a(n) = 14 + (n - 1)-3
a(n) = 14 -3n + 3
a(n) = 14 + 3 - 3n
a(n) = 17 - 3n
The explicit formula a(n) =
a(n) = 17 - 3n

j = 6
5(4) + 12
5 times 4 = 20
20 + 12 = 32
5(6) + 12

Your Nana gives you $50 for making all A’s/B’s on your last report card. You have been eying a new pair of Crocs + their fancy charms which total to $65. However, Crocs is running a sale for 30% off your total purchase. Do you have enough money to FINALLY get yourself those new Crocs?
Please have an explanation I will give you BRAINLIEST
Answer:
Yes you have enough money because with the dicound the crocs are $45.50
Step-by-step explanation:
u have $50 the crocs is $65 but have 30% off
$65 with 30% off is $45.50
Answer:
YAY, you can buy the Crocs!
Step-by-step explanation:
First we divide $65/100% to find one percent.
1% = 0.65
100% (original price) - 30% (sale) = 70% --> so the Crocs cost 70% their original price.
0.65 (1%) x 70 = $45.50 (final price of Crocs)

A rowing team rowed 120 kilometers while going with the current in the same amount of time as it took to row 20 kilometers going against the current. The rate of the current was 10 kilometers per hour. Find the rate of the rowing team in still water.
Answer:
100/x+6=20/x-6
100x-600=20x+120
80x=720
x=9 miles an hour as the rowing teams' rate in still water

Answer:
m<F= 44 degrees
length FH= 14.50 which would be 15
length GF= 20.15 which would be 20
perimeter= 48.65 which would be 49
Step-by-step explanation:
I took 90-46 to find F
Used tan46= x/14 to find FH
Used cos46=14/y to find GF

Answer:
x + 6, y - 4
Step-by-step explanation:
The original image would be the blue triangle, so you need to see how many units it takes to get to the red triangle.
Let's focus on R and R'.
You need to move 6 units to the right, and 4 units down to get from R to R'.
It would then be the same for the other two points.

Solve by elimination:
4x + 4y = 4
Answer:
x=−y+1
Step-by-step explanation:
Let's solve for x.
4x+4y=4
Step 1: Add -4y to both sides.
4x+4y+−4y=4+−4y
4x=−4y+4
Step 2: Divide both sides by 4.
4x = −4y+4
4 = 4
x=−y+1

does anyone know what the answer is ?
Answer:
Volume of the cylinder is 588π cm³ Or 1846.32 cm³
Step-by-step explanation:
Area of a cylinder is given by the formula,
Volume = πr²h
Here, r = Radius of the circular base
h = Height of the cylinder
From the picture attached,
Radius of the given cylinder = 7 cm
Height of the cylinder = 12 cm
By substituting these values in the formula,
Volume of the cylinder = π(7)²(12)
= 588π cm³
≈ 1846.32 cm³
Therefore, volume of the cylinder is 588π cm³ Or 1846.32 cm³.
