There are 16 sixth graders and 20 seventh graders in the robotics club. For the first project the club sponsor wants to organize the club members into equal size groups. Each group will have only sixth graders or only seventh graders how may students will be in each group if each group has the greatest possible numbers of club members?

Answers

You will have 9 groups and the max will be 4 people in each group

Answer:

There will be 4 students in each group and there will be 9 groups.

Step-by-step explanation:

There are 16 sixth graders and 20 seventh graders in the robotics club.

As we have to find the number of students that will be in each group if each group has the greatest possible numbers of club members, so we will find the HCF or highest common factor of 16 and 20.

16 = 2 x 2 x 2 x 2

20 = 2 x 2 x 5

HCF = 2 x 2 = 4

So, 16 sixth graders will be divided in [tex]\frac{16}{4}=4[/tex] groups

20 seventh graders will be in [tex]\frac{20}{4}=5[/tex] groups

total groups = [tex]4+5=9[/tex]

Hence, total there will be 9 groups with 4 students in each group.

George is saving for a mortgage on a $125,000 house. He needs 20 percent for a down payment. He currently has $22,000. How long will it take George to save the rest of the money when he earns 5 percent interest per year?

(This is an economics question)

Will it be 2years, 1year, 3years or 5years?

Answers

George will have enough money in 3 years. This is because at 5 percent interest per year, in one year he will have $23,100. In two years, he will have $24,155. In 3 years he will have $25,362.75 which will put him slightly over his goal of a 20% down payment.

Answer:

4. FH bisects ∠GFI, m∠EFG = 4y + 8 and m∠HFI = 2y + 6. Find m∠EFH.


please help me solve this

Answers

Angle EFH is 134 degrees.

Answer:

m∠EFH=134

Step-by-step explanation:

FH bisects ∠GFI

So m<GFH=m<HFI

m∠EFG = 4y + 8 and m∠HFI = 2y + 6

m<GFH=2y+6

[tex]m<EFG+m<GF+m<HFI= 180[/tex] because its a linear pair

[tex]4y+8+2y+6+2y+6=180[/tex]

combine like terms and solve for y

[tex]8y+20=180[/tex]

Subtract 20 from both sides

[tex]8y=160[/tex]

Divide both sides by 8

y=20

m∠EFH=m<EFG+m<GFH

m∠EFH=[tex]4y+8+2y+6=6y+14=6(20)+14=134[/tex]

Of video game that originally cost $25.99 is on sale for 50% off if you have $14 would you have enough money to buy the video game explain (estimate)

Answers

Just round 25.99 to 26 and divide it by two. This gives you 13, which is less than 14.. You would be able to buy the video game.

Final answer:

After calculating 50% of $25.99, which is approximately $13, we find that the estimated sale price of the video game is $13. Therefore, if the student has $14, they will have enough money to buy the discounted video game.

Explanation:

The student is asking whether $14 would be enough to purchase a video game that is on a 50% off sale from its original price of $25.99. To find the sale price, we can take 50% of the original price and subtract it from the original price itself.

First, calculate 50% of $25.99: (0.50) imes $25.99 = $12.995. Since we are estimating, round the 50% value to $13. Now, subtract that from the original price to get the sale price: $25.99 - $13 = $12.99 (rounded to $13 for easier calculation).

In this estimate, the sale price is $13, which means that if the student has $14, they would have enough money to buy the video game on sale because $14 is greater than $13. Therefore, they will have $1 left after the purchase.

mississippi live streaming weather radio broadcast from NOAA weather stations gives local weather updates every 18 minutes. The first update is at 2:00pm. you turn on the radio on at 5:30pm. How long will you have to wait for the next weather update?

Answers

Since they give updates every 18 minutes, thus any time being a multiple of 18 after 2 pm will be the time they give update.

5:30 pm is 3 hours 30 minutes for 2 pm or 150 minutes from 2 pm.

In 150 minutes, there are eight 18 minutes that have passed and is remaining 6 minutes for the next multiple of 18.

Therefore, you have to wait for 6 minutes for the next weather update.
Note that 5:30pm is 3 hours and 30 minutes from 2:00pm. And 3 hours 30 minutes is equivalent to 3*60 + 30 = 210 minutes. Since the local weather updates every 18 minutes, we have to wait for multiples of 18 minutes for the next weather update. We can see that 18 goes into 210 eleven times with a remainder of 12. So we're 12 minutes pass the latest weather update at 5:00pm, meaning that we have to wait 6 minutes more for the next weather update.

Thus the answer is 6 minutes. 

Eric biked 1 km 125 m on Monday. On Tuesday, he biked 375 m less than on Monday. How far did he bike both days

Answers

First, let's convert 1 km 125 m into metres.

what is the vertex , x coordinates , and x intercepts of y=2x ^2 + 4x-30

Answers

5.1      Find the Vertex of   y = x2-2x-15

Parabolas have a highest or a lowest point called the Vertex .   Our parabola opens up and accordingly has a lowest point (AKA absolute minimum) .   We know this even before plotting  "y"  because the coefficient of the first term, 1 , is positive (greater than zero). 

 Each parabola has a vertical line of symmetry that passes through its vertex. Because of this symmetry, the line of symmetry would, for example, pass through the midpoint of the two  x -intercepts (roots or solutions) of the parabola. That is, if the parabola has indeed two real solutions. 

 Parabolas can model many real life situations, such as the height above ground, of an object thrown upward, after some period of time. The vertex of the parabola can provide us with information, such as the maximum height that object, thrown upwards, can reach. For this reason we want to be able to find the coordinates of the vertex. 

 For any parabola,Ax2+Bx+C,the  x -coordinate of the vertex is given by  -B/(2A) . In our case the  x  coordinate is   1.0000  

 Plugging into the parabola formula   1.0000  for  x  we can calculate the  y -coordinate : 
  y = 1.0 * 1.00 * 1.00 - 2.0 * 1.00 - 15.0
or   y = -16.000

Given that the hypotenuse of this right triangle is 25 cm long and that tan(Θ) = 3 Find the values of x and y, accurate to the nearest tenth. A) x ≈ 7.9; y ≈ 23.7 B) x ≈ 23.7; y ≈ 7.9 C) x ≈ 7.9; y ≈ 26.4 D) x ≈ 26.4; y ≈ 79.1

Answers

The wording of this problem indicates that there was an illustration.  Could you possibly share that illustration?

Working without an illustration:

If tan theta = 3, then tan theta = opp/adj = 3/1.  This tells us that the opp side is 3 times as long as is the adj. side.  Let x be the shorter side, i. e., let x represent the adjacent side; then y is the longer side and represents the opposite side.

Then y = 3x (the opp side is 3x the adj side in length).

Applying the Pyth. Thm.    a^2 + b^2 = c^2,

x^2 + (3x)^2 = hyp^2 = (25 cm.)^2

So x^2 + 9x^2 = (625 cm^2)

10x^2 = 625 cm^2, or x^2 = (625 cm^2) / 10 = 62.5 cm^2

x = 7.91 cm.  Therefore, y = 3(7.91) = 23.72 cm.

We were supposed to round off these answers to the nearest 10th cm.
Therefore, x = 7.9 cm and y = 23.7 cm

Would that be A, B, C or D?

Answer:


Step-by-step explanation:

The right triangle above you can use SOHCAHTOA and determine that tanθ =

y

x

. Replacing tanθ with 3 you get

3 =

y

x


3x = y


Then use the Pythagorean Theorem to

x2 + y2 = 252. Replace y with 3x

x2 + 9x2 = 625

10x2 = 625

x2 =

625

10


x =

25

10

= 7.9


Since,

y = 3x

y = 3(7.9) = 23.7


x ≈ 7.9; y ≈ 23.7


what is the function of delta sign in maths

Answers

The uppercase delta Δ means "change in" so for example: Δx = difference between two x values.

The lowercase delta which Brainly does not have, looks like a squiggly lowercase d. It generally means "very small change in".

Final answer:

The delta sign (Δ) in mathematics indicates a change in a certain quantity, calculated by subtracting the initial value from the final value, commonly used for indicating displacement in physics.

Explanation:

The delta sign (uppercase Greek letter delta, Δ) is commonly used in mathematics to denote a change in a certain quantity. When we say Δx, it signifies the 'change in x' or the difference between the final and initial values of 'x'. This is typically calculated by subtracting the initial value xo from the final value xf. For instance, if we're calculating displacement, which is a change in position, we subtract the starting position xo from the ending position xf to get Δx. The SI unit for displacement is the meter, but other units such as kilometers may also be used, requiring conversion to meters for consistency in calculations.

Hence, the required standard form is 104.

Who sets the price in a monopolistic competition?

Answers

The producer sets the price in a monopolistic competition.

Further Explanation:

Monopolistic Competition:

Monopolistic competition is a type of competition where a large number of seller offer similar but not perfect substitute products. Each producer offers a different product at different price based on the exclusive characteristic of the product. Major characteristics of monopolistic competition are as follows:

• Different product  

• Large number of producers  

• Freedom of entry and exit

• Market power (Producer)

Setting the price in monopolistic competition:

In monopolistic competition, the producer has the power to pricing power. In this type of competition, the producers offer different products as compared to other competitors and charge the customer according to their product differentiation. Therefore, they have the power to set and change the price on the basis of their offered product.

Thus, the producer sets the price in a monopolistic competition.

In monopolistic competition,

The price is typically set by individual firms or businesses rather than a centralized authority.

We have,

Each firm has some degree of market power, allowing them to differentiate their products or services from their competitors.

Firms in monopolistic competition have the freedom to set their prices based on factors such as production costs, demand for their product, market conditions, and desired profitability.

They aim to find the price that maximizes their own profits or achieves their specific business objectives.

However, it's important to note that in monopolistic competition, there is competition among firms, albeit with differentiated products.

As a result, firms must also consider the prices set by their competitors to remain competitive and attract customers.

Thus,

In monopolistic competition, the price-setting decision lies with the individual firms, balancing their own considerations and market dynamics to determine the optimal price for their product or service.
