Answer: 1)100ways and 2)90ways
Step-by-step explanation:
Given :-The 10 students who completed a special flying course are waiting to see if they will be awarded the one Distinction or the one Merit award for their efforts.
Ways can the two awards be given if the same student can receive both awards (i.e repetition is allowed)
=10×10=100ways
Ways can the two awards be given if the same student cannot receive both awards(i.e. repetition is not allowed)
=10×9=90ways
Final answer:
The number of ways two awards can be given out to 10 students is 100 when the same student can win both awards, and 90 when different students must win each award.
Explanation:
The student's question deals with the number of ways two awards can be given out to a group of 10 students under two different scenarios: one where the same student can receive both awards, and the other where the same student cannot receive both awards. This is a problem of permutations and combinations, a fundamental concept in probability and statistics.
Scenario 1: Same Student Can Receive Both Awards
In the first scenario, the same student can receive both the Distinction and the Merit award. Since there are 10 students and each student can potentially receive each of the two awards, we have 10 choices for the Distinction award and 10 choices for the Merit award. The total number of ways the two awards can be given out is simply the product of these two numbers:
10 (for Distinction) × 10 (for Merit) = 100 ways
Scenario 2: Different Students Receive Awards
In the second scenario, the same student cannot receive both awards. This means that once a student has been given one award, they cannot receive the other one. For the Distinction award, there are still 10 possible students. However, for the Merit award, there are only 9 remaining choices since the Distinction awardee cannot be considered:
10 (for Distinction) × 9 (for Merit) = 90 ways

One health club charges a $44 sign-up fee and $30 per month. Another health club charges a $99 sign-up fee and $25 per month. For what number of months is the cost the same?
Setting up algebraic equations to represent the costs of each club, one can solve for the number of months where the costs are the same. The cost of both health clubs is equal for 11 months.
Explanation:In mathematics, problems like this can be solved using algebra, setting the cost of club 1 equal to the cost of club 2 and then solving for the variable, in this case, the number of months for which the costs are equal. Club 1 charges a $44 sign-up fee and $30 per month, which can be written as 44 + 30m (where 'm' represents the number of months). Club 2 charges a $99 sign-up fee and $25 per month, which can be written as 99 + 25m. Set these two equations equal: 44 + 30m = 99 + 25m and solve for m. Subtract 25m from both sides to get 5m = 55, then divided both sides by 5 to find m = 11. So, the cost of membership at these two health clubs is the same for 11 months.

Mai has 40 tens. Write how many hundreds. Write the number.
The number is 400.
To find out how many hundreds Mai has, let's understand that each ten is equal to 10. So, if Mai has 40 tens, we can calculate how many ones that is in total:
40 tens * 10 = 400 ones
Now, since there are 100 ones in one hundred, we divide the total number of ones by 100 to find out how many hundreds Mai has:
400 ones / 100 = 4 hundreds
So, Mai has 4 hundreds.
Now, let's write the number:
If Mai has 4 hundreds, it means the digit in the hundreds place is 4. Since she has no tens, the digit in the tens place is 0. And since she has no ones, the digit in the ones place is 0.
Three hundred millions, 6 millions, 4 tens thousands, six hundred, eight
I think the answer to this question is 306,040,608. If we are supposed to write it out then it is (3 × 100,000,000) + (6 × 1,000,000) + (4 × 10,000) + (6 × 100) + (8 × 1)
what must you do to undo a square root in order to solve an equation that includes a radical expression
To undo a square root in an equation, you square both sides of the equation. This will eliminate the square root on one side and gives you the original value under the square root. It simplifies the equation, making it easier to solve.
Explanation:To undo a square root in an equation that includes a radical expression, you have to square that part of the equation. Here is an example to illustrate this:
Suppose you have the equation √x = 2. To undo the square root, you need to square both sides of the equation: (√x)² = 2². This operation results in the equation x = 4.
Remember, when squaring a square root, the result is the original number under the radical. Therefore, the process of 'undoing' the square root is to square the radical expression. This helps us to have equations in a simpler form, which further makes it easier for us to solve.

A smaller square park has an area 3600 square meters what is the length of one side of the park
Squares have equal side lengths, so that is why the question is only asking for one side length.
The area of a square is calculated using the formula s^2, where s stands for a side of the square.
To find the length of one side of the park, you can take the given area (3,600 m^2) and square root it. This would give you the length of one side of the square park.
√3,600 = 60
The length of one side of the park is 60 meters.
The length of one side of the square park with an area of 3600 square meters is 60 meters.
Explanation:Given that the area of the square park is 3600 square meters, we can calculate the length of one side by taking the square root of the area. This is because the area of a square is calculated by squaring the length of one side (side length X side length). So, if we reverse this process by taking the square root, we find the length of one side.
So, "the length of one side of the park is the square root of 3600 which equals 60 meters".

what is 34% of 510.
Tracereed,
In order to solve this question you have to divide 34 by 100 then divide that by 510.
[tex]100 \div 34[/tex][tex]510 \div 34 = 2.9411764705882[/tex][tex]15 \div 100 =173.4 [/tex][tex]173.4[/tex]Therefore "173.4 is 34% of 510!"
Hope this helps!
To find 34% of 510, first write 34% as a decimal by moving the decimal point two places to the left to get .34.
Next, the word "of" means multiply, so we are going to multiply.
(.34) (510) = 173.4
Therefore, 34% of 510 is 173.4.
Small juice boxes come in packages of 6. Yogurt treats come in packages of 10. Paula wants to have the exact same number of each item. How many bottles of juice and individual yogurt treats will she have altogether? How many packages of each will she need?
We can see here that Paula will need 5 packages of small juice boxes and 3 packages of yogurt treats to have the exact same number of each item, resulting in a total of 30 juice boxes and 30 yogurt treats.
Since small juice boxes come in packages of 6 and yogurt treats come in packages of 10, Paula wants to have the exact same number of each item. This means that both the number of juice boxes (J) and the number of yogurt treats (Y) must be multiples of the least common multiple (LCM) of 6 and 10.
The LCM of 6 and 10 is 30.
So, Paula needs to have a multiple of 30 for both the number of juice boxes and the number of yogurt treats.
To find the values of J and Y, we can choose any multiple of 30.
Let's say Paula decides to have 30 juice boxes (J = 30) and 30 yogurt treats (Y = 30).
Now, let's find out how many packages of each she will need:
For juice boxes (packages of 6): J / 6 = 30 / 6 = 5 packages
For yogurt treats (packages of 10): Y / 10 = 30 / 10 = 3 packages
So, Paula will need 5 packages of small juice boxes and 3 packages of yogurt treats to have the exact same number of each item, resulting in a total of 30 juice boxes and 30 yogurt treats.

The midpoint of CD is E (-1,0). One endpoint is C (5,2). What are the coordinates of the other endpoint?
The answer is (2, 1)
ExplanationWe can solve this by using midpoint formula
[tex]M = (x_{1} + x_2)/2, (y_1 + y_2} ) /2[/tex]
because in a plane the coordinates of midpoint of a line is the average of each other coordinates.
So,
[tex]x_1 = -1, x_2 = 5[/tex]
[tex]y_1 = 0. y_2 = 2[/tex]
Putting values in formula as
[tex]M = (-1+5) / 2, (0+2) / 2[/tex]
[tex]M = (2, 1)[/tex]
Answer: The required co-ordinates of the endpoint D are (-7, -2).
Step-by-step explanation: Given that the midpoint of CD is E (-1,0) and one endpoint is C (5,2).
We are to find the co-ordinates of the other endpoint D.
Let (x, y) represents the co-ordinates of the endpoint D.
We know that
the co-ordinates of the midpoint of a line segment withe endpoints (a, b) and (c, d) is given by
[tex]\left(\dfrac{a+c}{2},\dfrac{b+d}{2}\right).[/tex]
Therefore, according to the given information, we have
[tex]\left(\dfrac{5+x}{2},\dfrac{2+y}{2}\right)=(-1,0)\\\\\\\Rightarrow \dfrac{5+x}{2}=-1\\\\\Rightarrow 5+x=-2\\\\\Rightarrow x=-2-5\\\\\Rightarrow x=-7[/tex]
and
[tex]\dfrac{2+y}{2}=0\\\\\Rightarrow 2+y=0\\\\\Rightarrow y=-2.[/tex]
Thus, the required co-ordinates of the endpoint D are (-7, -2).

By Subtracting the given Expression 9,002,000 - 5•[tex]10^6[/tex] we get Option C. 4.002 x [tex]10^4[/tex].
To subtract 5 • [tex]10^6[/tex] from 9,002,000, we simply perform the arithmetic operation as follows:
9,002,000 - 5 • [tex]10^6[/tex]
Step 1: Subtract 5 • [tex]10^6[/tex] from 9,002,000
= 9,002,000 - 5 • [tex]10^6[/tex]
= 9,002,000 - 5,000,000
Step 2: Perform the subtraction
= 9,002,000 - 5,000,000
= 4,002,000
Now, we have the result of 4,002,000. However, we need to write this answer in scientific notation.
In scientific notation, a number is written as a product of two parts: a coefficient and a power of 10. The coefficient must be greater than or equal to 1 and less than 10.

adam prepares a meal of shrimp and brown rice. it must contain exactly 6 g of fat and 10 mg of iron. each 5oz serving of shrimp contains 2 g fat and 5 mg iron. each 1 cup of brown rice contains 6 g fat and 7 mg iron. how many servings of shrimp and brown rice should be in the meal?
Answer:
Adam needs 9/8 of a 5oz serving of shrimps (which equals to 5.625 oz) and 5/8 of a cup of brown rice (which is around 10 tablespoons).
Explanation:
You are given:
every serving of shrimp contains 2g of fat and 5mg of iron;
every serving of rice contains 6g of fat and 7mg of iron;
each meal should have 6g of total fat and 10mg of total iron.
You need to set a system of equation: let's call
s = quantity of shrimps
r = quantity of rice
The equation for the total fat will be: the quantity of fat in the serving of shrimps plus the quantity of fat in the serving of rice must be equal to 6g
2s + 6r = 6 (1)
Similarily:
the quantity of iron in the serving of shrimps plus the quantity of iron in the serving of rice must be equal to 10g
5s + 7r = 10 (2)
In order to solve the system, solve for s in equation (1):
s = (6-6r)/2 = 3 - 3r (3)
Substitute in equation (2):
5(3 - 3r) + 7r = 10
and solve for r:
15 - 15r + 7r = 10
8r = 5
r = 5/8
Substitute the value of r in equation (3):
s = 3 - 3×5/8 = 9/8
Therefore Adam would need 9/8 of a 5oz serving of shrimps and 5/8 of a 1 cup of brown rice for each meal.
