At a family reunion, there only blood relatives, consisting of children, parents, and grandparents, in attendance. There were 400 people total. There were twice as many parents as grandparents, and 50 more children than parents. How many children, parents, and Grandparents were in attendance?

Show up all steps please

Answers

Solving the system of equations, the number of children, parents, and Grandparents who were in attendance are 190, 140 and 70 respectively.

Let C, P and G denotes the number of children, parents and the grandparents in the function.

We get the system of equations,

C + P + G = 400 [equation 1]

P = 2G  ⇒ G = P/2 [equation 2]

C = P + 50 [equation 3]

Substituting 2 and 3 in 1,

(P + 50) + P + (P/2) = 400

2P + P/2 = 350

5/2 P = 350

P = 140

C = P + 50 = 140 + 50 = 190

G = P/2 = 140/2 = 70

Hence the number of parents = 140, grandparents = 70 and children = 190.

By using the head to tail, the addition of the vectors [tex]\vec a + \vec b[/tex] is (3, -5).

How to add vectors by using the head to tail method?

In Geometry, a vector is typically composed of two end points. First, is the starting point which is commonly known as a "tail" and the second (ending) point that is commonly known as a "head."

Additionally, the head to tail method of adding two vectors requires drawing the first vector ([tex]\vec a[/tex]) on a graph and then placing the tail of the second vector ([tex]\vec b[/tex]) at the head of the first vector. Finally, the resultant vector would be drawn from the tail of the first vector ([tex]\vec a[/tex]) to the head of the second vector ([tex]\vec b[/tex]).

Next, we would add the two (2) vectors algebraically as follows;

[tex]\vec a + \vec b[/tex] = (4, -3) + (-1, -2)

[tex]\vec a + \vec b[/tex] = [(4 + (-1)), (-3 + (-2))]

How much running area is there?

R = 20 ft

I WILL MARK YOU BRAINLIEST AND GIVE 30 POINTS

Answers

With a radius of 20 feet and 10 rounds traversed, the total distance equates to approximately 1256.6 feet.

How to solve

When calculating the circumference (C) of a circle, the formula 2 * π * radius (R) is employed.

Taking into consideration R = 20 feet, we shall arrive at the following figure:

C = 2 * π * 20

C ≈ 2 * 3.14159265359 * 20

C ≈ 125.66 feet

If we use this calculation to determine the total distance covered after running 10 laps around a track, our equation morphs into Circumference (C) multiplied by the Number of laps (L).

When L equals 10, it follows that:

Total distance ≈ 125.66 feet * 10

Total distance ≈ 1256.6 feet

Therefore, with a radius of 20 feet and 10 rounds traversed, the total distance equates to approximately 1256.6 feet.

They know there will also be guests stopping by who may have come from other parties. For ordering​ purposes, they will count each of these​ "drop-in" guests as half a guest. How much of each food item should and order for a graduation party with ​drop-in guests?

Answers

To order enough food for a graduation party with drop-in guests, they should order:

112 + 1.4x pieces of fried chicken

14.64 + 0.183x pounds of meat

41 + 0.5125x pounds of lasagna

If we consider each "drop-in" guest as half a guest, then the total number of guests becomes:

40 + 0.5x, where x is the number of "drop-in" guests.

To determine how much of each food item to order, we can use the recommended amounts as a guide and scale them up based on the total number of guests:

Fried chicken: 28 pieces for 10 guests, so we need 28 * (40 + 0.5x) / 10 = 112 + 1.4x pieces.Meat: 3.66 pounds for 10 guests, so we need 3.66 * (40 + 0.5x) / 10 = 14.64 + 0.183x pounds.Lasagna: 10.25 pounds for 10 guests, so we need 10.25 * (40 + 0.5x) / 10 = 41 + 0.5125x pounds.

So, to order enough food for a graduation party with drop-in guests, they should order:

112 + 1.4x pieces of fried chicken

Answers

a) For Super Home, the superior (or dominant) tactic is to magnify the size of the store and parking lot. This is, regardless of what Great Home does, Super Home's payoff is amplified when it expands its size ($1m vs $0.4m if Great Home amplifies; $3.2m vs $2m if Great Home passes).

What is the best strategy for Great Home?

Similarly, for Great Home, the logical (or dominant) strategy is also to expand the size of the store and parking lot. This is because, although unrelated to Super Home's decision, Great Home's payoff is augmented when it enlarges its size ($1.5m vs $0.6m if Super Home magnifies; $3.4m vs $2.5m if Super Home disallows).

b) If both stores implement their authoritative plan, Great Home will witness an annual profit growth of $1.5 million, and Super Home will observe an annual profit growth of $1 million.

A Nash Equilibrium comprehends a state wherein each player chooses their finest ploy given the stratagems selected by the other participant(s), and no player can modify their consequence through exclusively adapting their strategy. In this case, the Nash Equilibrium exists in (Increase, Increase), which spans over the payoffs ($1.5m, $1m).

c) The conjunctive approach both stores should commit to would be for Great Home to amplify the size of its store and parking lot, and Super Home to renounce increasing its size.

Under this harmonized approval, the annual profit growth for Great Home will come out at $3.4 million, and for Super Home, it will arrive at $0.4 million. This system gives rise to a higher collective gain compared to the Nash Equilibrium.

Let v = 5i - 2j Find ||4v||

Answers

The magnitude of the vector 4v is 4 times the magnitude of v, which is equal to 4 √29.

Given the vector v = 5i - 2j, we can find the magnitude or norm of the vector ||v|| using the formula:

||v|| = √(v · v)

where · denotes the dot product of the vector with itself.

Substituting the values of the vector v, we have:

||v|| = √((5i - 2j) · (5i - 2j))

Expanding the dot product using the distributive law, we get:

||v|| = √(25i² - 20ij + 4j²)

Since i² = j² = 1 and ij = ji = 0, we can simplify this expression to:

||v|| = √(25 + 4) = √29

Thus, the magnitude of the vector v is √29.

Now, we need to find the magnitude of the vector 4v. Using the property that ||kv|| = |k| ||v|| for any scalar k and vector v, we have:

||4v|| = |4| ||v|| = 4 √29

In summary, the magnitude of the vector v is √29, and the magnitude of the vector 4v is 4 √29.

A bag of apples weighs 8 7 8 pounds. A crate of bananas is 6 times as heavy as the apples. How much heavier are the bananas than the apples?

Answers

The crate of bananas is heavier than the bag of apples by 53 1/4 pounds.

How much heavier are the bananas than the apples?

An apple and a banana are both kinds of fruits. They both weigh differently.

Weight of a bag of apple = 8 7/8 pounds

Weight of a crate of bananas = 6 times as heavy as the apples

= 6 × 8 7/8

= 6 × 71 /8

= 426 / 8

= 53 1/4 pounds

Therefore, the weight of a crate of bananas is 53 1/4 pounds

Which shows the correct first step to solving the system of equations in the most efficient manner?
3x+2y-17
x+4y=19
O x=-4y+19
-2y+17
3
O x-
O4y=-x+19
Oy=-3x+17

Answers

Answer:

  (a)  x = -4y +19

Step-by-step explanation:

You want to know a good first step for solving the system of equations in an efficient manner.

3x +2y = 17x +4y = 19

Substitution

One way to solve these equations is by substitution. To do that, we typically write an expression for one of the variables in terms of the other. It is efficient to choose a variable that already has a coefficient of 1.

Here, a useful first step is to solve the second equation for x:

  x = -4y +19

__

Additional comment

Then the solution proceeds with substitution for x:

  3(-4y +19) +2y = 17

  -10y +57 = 17

  -10y = -40

  y = 4

  x = -4(4) +19 = 3

The solution is (x, y) = (3, 4).

Another reasonable first step is to subtract the second equation from twice the first:

  2(3x +2y) -(x +4y) = 2(17) -(19)

  5x = 15

  x = 3

  3 +4y = 19 . . . . . . substitute for x in the second equation

  y = (19 -3)/4 = 4

The "addition" or "elimination" method shown second is also shown using 5 steps, but these are generally more complicated steps than the ones shown for the "substitution" solution. It appears the substitution solution probably is "the most efficient" in this case.

Bacteria in a dirty glass triple 4 hours. If there are 25 bacteria to start, how many in the glass
after 1 day?

Answers

If the number of bacteria triples every 4 hours, then after 1 day (24 hours), the number of bacteria will triple 6 times.

Tripling a number 6 times is the same as multiplying it by 3 raised to the power of 6, or 3^6.

So, if there are 25 bacteria to start, the number of bacteria after 1 day will be:

25 x 3^6 = 25 x 729 = 18,225 bacteria.

Answer:

Step-by-step explanation:

It is not possible to accurately determine the number of bacteria in the glass after 4 hours without additional information such as the rate of bacterial growth, the environmental conditions, and whether any bacteria were removed or added during that time.
