The circumfrence is 26cm what is the diameter to 1dp
Answer:
The diameter is 8.3cm.
Step-by-step explanation:
The circumference is the distance all the way around a circle. To find circumference, multiply pi times diameter:
C = pi • d
Fill in given circumference.
26 = pi • d
Divide both sides by pi (you should use a calculator) in this question it doesn't happen to matter if you use a pi button or 3.14 for pi.
26/3.14 = d
8.276057 = d if you use the pi button.
or,
8.28025 = d if you use 3.14
Both of these round to 8.3, since the question asked for one decimal place (1dp)

If the sporting goods store has 100 gifts each in stock, then the number of customers who get t-shirts and drinking bottles are 2 customers, namely the 40th customer and the 80th customer.
Determine the LCM(Least Common Multiples)In finding the LCM, we also use prime factorization, namely multiplying all the factor numbers and if there are the same, take the largest value, if both are the same, then take one of them.
For example, determine the LCM of 30 and 48
30 = 2 x 3 x 5
48 = 2 x 2 x 2 x 2 x 3 = 2⁴ x 3
The LCM of 30 and 48 is 2⁴ x 3 x 5 = 240
The above Question can be solved with the concept of LCM
where the 8th customer gets a T-shirt and the 10th customer gets a water bottle. To find out which customer gets the two gifts, then look for LCM from 8 and 10

4v-18 = 6v - 36
2.) Move 6v to the other side by subtracting from both sides
4v - 6v -18 = -36
3.) Move 18 to the other side by adding 18 on both sides
4v - 6v = 18 + -36
4.) Combine like terms
-2v = -18
5.) Divide -2 on both sides to get v by itself
v = 9
Answer:
the answer is 9

Answer:
To solve this problem, we need to calculate the cost of each travel and instruction option and then determine which options Treena can afford with her $1000 scholarship.
Option 1: Air travel and individual instruction
Travel cost: $335
Instruction cost: 7 x $60 = $420
Total cost: $335 + $420 = $755
Option 2: Air travel and group instruction
Travel cost: $335
Instruction cost: 7 x $40 = $280
Total cost: $335 + $280 = $615
Option 3: Train travel and individual instruction
Travel cost: $125
Instruction cost: 7 x $60 = $420
Total cost: $125 + $420 = $545
Option 4: Train travel and group instruction
Travel cost: $125
Instruction cost: 7 x $40 = $280
Total cost: $125 + $280 = $405
Now we need to determine which options Treena can afford with her $1000 scholarship. We'll start with the most expensive option and work our way down.
Option 1: $755
This option is too expensive for Treena's $1000 scholarship.
Option 2: $615
This option is also too expensive for Treena's $1000 scholarship.
Option 3: $545
This option is within Treena's budget, but she won't have any money left for food.
Option 4: $405
This option is also within Treena's budget, and she'll have $595 left for food.
Therefore, Treena's choices of travel and instruction plans that she could afford to make are:
- Train travel and group instruction with $595 left for food
- Train travel and individual instruction with no money left for food

b. A five card hand, where four of the cards are the same, i. E. Four Aces, or four Kings, etc. , is called getting a "four of a kind". What is the probability of getting a "four of a kind"? Round your answer to five decimal places
The probability of getting: A. a five-card hand that has three Jacks and two Queens is 0.000009, or 0.000923% and B. a "four of a kind" is 0.00024, or 0.02401%.
A. The probability of getting a five-card hand that has three Jacks and two Queens can be calculated by using the formula:
P(3 Jacks and 2 Queens) = C(4,3) x C(4,2) / C(52,5)
Where C(n,k) is the combination of n items taken k at a time.
= (4 x 6) / 2598960

Imani sold 2 rolls of plain wrapping paper and 11 rolls of holiday wrapping paper for a total of $208. Lea sold 11 rolls of plain wrapping paper and 9 rolls of holiday wrapping paper for a total of $320. What is the cost each of one roll of plain wrapping paper and one roll of holiday wrapping paper?
Answer: Let's represent the cost of one roll of plain wrapping paper as x, and the cost of one roll of holiday wrapping paper as y. We can write two equations based on the information given:
2x + 11y = 208
11x + 9y = 320
We can use these equations to find the values of x and y. Solving the first equation for y:
y = (208 - 2x) / 11
We can substitute this expression for y into the second equation to eliminate y:
11x + 9((208 - 2x) / 11) = 320
11x + 208 - 18x / 11 = 320
11x - 18x / 11 = 320 - 208
-7x / 11 = 112 / 11
-7x = 112
x = -16
So one roll of plain wrapping paper costs -16 dollars, which is not possible. This means there is no solution for this system of equations, and therefore the problem has no solution.
