Sean and his sister, Betty equally mow 8/9th the total area of a lawn. What fraction of the total area did each of them mow? (Show ur work plz)

Answers

Answer 1

Since they mowed [tex]\frac{8}{9}[/tex] of the lawn in two equal parts, we need to split the pieces that were mowed into two equal groups. We know that in total they mowed 8 out of the total 9 pieces of lawn, so two equal groups that make 8 would be of size 4, since [tex]\frac{8}{2}=4[/tex]. Then they each mowed [tex]\frac{4}{9}[/tex] of the lawn.

Answer 2

Using the division operation, the fraction of the total area mowed by each person is [tex] \frac{4}{9}[/tex]

Total fraction mowed = [tex] \frac{8}{9}[/tex]

Number of persons who mowed the area = 2

Since, the same amount of area ws mowed by each person, then the area mowed per person can be calculated thus :

Total Area mowed ÷ number of persons

[tex] \frac{48}{9} \div 2 = \frac{4}{9}[/tex]

Hence, each person mowed [tex] \frac{4}{9}[/tex]

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.

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.

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

1 km = 1000 m
1.125 km - 1,125 m

On Tuesday, Eric biked 375 metres fewer than on Monday.
1125 - 375 = 750 m

One carpet cleaning cost are shown in the table. The relationship is linear. Find and interpret the rate of change and the initial value for this situation.

Answers

I see from the given data that each additional carpet after the first costs $50 each to have cleaned.

The first costs $125. Supposing we subtract $50 from that, we get $75. So, it sounds like it costs $75 just to get the carpet cleaners to your house.

The rule would then be $75 + $50x, where x : {1, 2, 3, 4, .... }

Let's check this result. Suppose x = 1. Will the charge be $125, as show in the table? $75 + $50(1) = $125. Correct.

Suppose x = 4. Will the charge be $275 as shown in the table?
$75 + $50(4) = $275. YES

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?

1. Write the ratio in the simplest form. 16:24 (1 point) 1:2 4:3 3:4 2:3

Answers

Any ratio can be simplified into its simplest form by dividing the numerator and denominator by the common factor.

The given ratio is 16:24. To bring the ratio in its simplest form we will look for the factors of 16 and 24 and look for the greatest number that divides both 16 and 24.

The greatest number that divides both 16 and 24 is 8.

16÷8=2

24÷8=3.

The ratio 16:24 in its simplest form is 2:3

The solution for the ratio in the simplest form is, 2 : 3

Given that,

16:24 is the specified ratio.

Now, By finding the largest integer that divides both 16 and 24 and the factors of 16 and 24, we may reduce the ratio to its most basic form.

Hence, 8 splits both 16 and 24 to the maximum possible extent.

So, we get;

16 / 8 = 2

24 / 8 = 3

Thus, the simplest form of the fraction is,

⇒ 16 : 24

⇒ 16 / 24

⇒ 2 / 3

It can be written as,

⇒ 2 : 3

So, the simplest form is,

⇒ 2 : 3

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 =

. Replacing tanθ with 3 you get

3 =

3x = y

Then use the Pythagorean Theorem to

x2 + y2 = 252. Replace y with 3x

x2 + 9x2 = 625

10x2 = 625

x2 =

625

x =

= 7.9

Since,

y = 3x

y = 3(7.9) = 23.7

x ≈ 7.9; y ≈ 23.7

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.

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.
