What is the degree of this pynomial?

Answer:  Yes, there is something missing.

Step-by-step explanation:  Given that Charlie gathers apples pears and plums. The number of apples and plums are 10 partners, there are the same number of apples and pears.

Since there are 10 partners of apples and plums, so

number of apples = number of plums = 10.

Also, number of apples and number of pears are same, therefore, number of pears = 10.

Thus, total number of fruits = 10+10+10 = 30.

Hence, Charlie couls gather 30 fruits.

So, this was missing in the calculation.

Charlie can be made to gather more fruit by maximizing the number of

apples gathered which gives a total of 19 fruits.

Response:

The question is a word problem

Number partners of 10 are numbers that add up to 10

Therefore;

The number of apples + The number of plums = 10

The number of apples = The number pears

Required:

The number of pieces of fruit Charlie could gather

Solution:

Let x represent the number of apples, gathered, we have the following equations;

The number of plums = 10 - x

The number of pears = x

Which gives;

Total number of fruit = x + 10 - x + x = 10 + x

Where;

1 ≤ x ≤ 9

The maximum number of fruit Charlie can gather is therefore, when x = 9,  which gives;

Answer:

12 slats can be made from a board i,e  42 feet long

Step-by-step explanation:

As per the given statement: A fence builder uses boards [tex]3\frac{1}{2}[/tex] feet long for the vertical slats on the fence.

We have to calculate how many slats can be made from a board that is 42 feet long.

Builder uses board [tex]3\frac{1}{2} = \frac{7}{2}[/tex] feet long for the vertical slats.

then;

for 42 feet long = [tex]\frac{42}{\frac{7}{2} } = 42 \times \frac{2}{7} = 6 \times 2 = 12[/tex] slats can be made.

Therefore, 12 slats can be made from a board that is 42 feet long.

Answer:

[tex](y-135)=45(x-3)[/tex]  

Step-by-step explanation:  

Let x represents the number of hours and y represents the number of miles.

We are told that Luz drives at an average speed of 45 miles per hour. She has driven for 3 hours and has traveled a distance of 135 miles.  

We can see from our given information that slope of line is 45 as with each increase in number of hours (x), change in distance (y) is 45.

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{135-0}{3-0}[/tex]

[tex]m=\frac{135}{3}[/tex]

[tex]m=45[/tex]

Since the equation of line in point-slope form is : [tex](y-y_1)=m(x-x_1)[/tex], where m represents slope of line and [tex](y_1,x_1)[/tex] represents a point the line passes through.

Upon substituting our given values in point-slope form of equation we will get,

[tex](y-135)=45(x-3)[/tex]  

Therefore, the equation represented in point-slope form will be: [tex](y-135)=45(x-3)[/tex].

Answer:

The slope of the linear equation is  45.

To find the distance between two point we use the formula

d = sqrt( (x2-x1)^2 + (y2-y1)^2)

d = sqrt((12--4)^2 + (11--19)^2)

d = sqrt((12+4)^2 + (11+19)^2)

d = sqrt((16)^2 + (30)^2)

d =sqrt(256+900)

d = sqrt(1156)

d =34

Answer:

13,200 Seconds, or 220 Minutes

Step-by-step explanation:

Since there are 2 employees working at the same time, so in 20 seconds, they will be tagging a total of 2 garments. So we can say the rate is:

rate = [tex]\frac{20 Seconds}{2 Garments}[/tex]

So how long would it take to tag 1320 garments?

We set up the ratio, cross multiply, and solve.

[tex]\frac{TimeInSeconds}{NumberOfGarments}=\frac{20}{2}=\frac{x}{1320}}\\\frac{20}{2}=\frac{x}{1320}\\20*1320=2x\\x=\frac{26400}{2}=13,200[/tex] seconds

Or in minutes, we divide by 60, so we have:

[tex]\frac{13,200}{60}=220[/tex] Minutes

Answer:

3 hours 40 minutes.

Step-by-step explanation:

We are told that we have 1320 garments and it takes an employee 20 seconds to tag a garment.

1 employee tags one garment in 20 seconds.

So garments tagged by 1 employees in 1 minute will be [tex]\frac{60}{20} =3[/tex] garments.

2 employees will tag 3*2=6 garments in 1 minute.

To find the total time it will take two employees to tag all the garments we will divide total number of garments by 6.

[tex]\text{Time taken by two employees to tag 1320 garments}=\frac{1320}{6}[/tex]

[tex]\text{Time taken by two employees to tag 1320 garments}=220[/tex]

Therefore, it will take 220 minutes or 3 hours and 40 minutes for 2 employees to tag 1320 garments.

Answer:

4 km/h

Step-by-step explanation:

We are told that Dina and Masha started out on a 10 km bike path at the same time.

Dina's biking speed is 5 km/h.

Let us find taken by Dina to cover 10 kn distance.

[tex]\text{Time}=\frac{\text{Distance}}{\text{Speed}}[/tex]

[tex]\text{Time taken by Dina to cover 10 km}=\frac{10km}{5\frac{km}{hr}}[/tex]

[tex]\text{Time taken by Dina to cover 10 km}=\frac{10km}{5}\times \frac{hr}{km}}[/tex]

[tex]\text{Time taken by Dina to cover 10 km}=2hr[/tex]

Therefore, Dina took 2 hours to complete 10 km.

Since both started at the same time, therefore, Masha also took 2 hours to complete 2 km less than Dina.

Let us find distance covered by Masha.

[tex]\text{Distance covered by Masha}=10\text{ km}-2\text{ km}=8\text{ km}[/tex]

Now let us find Masha's biking speed.

[tex]\text{Speed}=\frac{\text{Distance}}{\text{Time}}[/tex]

[tex]\text{Masha's biking speed}=\frac{8\text{ km}}{2\text{ hour}}[/tex]

[tex]\text{Masha's biking speed}=4\frac{\text{ km}}{\text{ hour}}[/tex]

Therefore, Masha's biking speed is 4 km per hour.

Step-by-step explanation:

We will assume that each bulb is of 100 kW (kilowatt).

We will calculate how much energy in kilowatt-hours the light bulb will use per year in kilowatts, by the number of hours in a year.

We have,

100 kW = 0.1 kW so the energy consumed in one year is,

[tex]0.1 \times 8760=876.0\text {kWh}[/tex]

Since there are 8760 hours in one year.

It is given that there are 9 bulbs so we need to have,

[tex]876 \times 9 = 7884 \text {kWh}[/tex]

It is given that 1 ton of coal produces 2460 kWh, so 4 tons of coal will produce,

[tex]4\times 2460= 9840 \text {kWh}[/tex]

We can observe that 4 tons of coal is producing 9840 kWh which is mroe than 7884 kWh. So, yes, 4 tons of coal can produce enough power to light 9 bulbs for a year.

The 4 tons of coal from the power plant will produce 9840 kilowatt hours of electricity. A single 60 watt light bulb consumes around 526 kilowatt hours in a year. Thus, the energy produced by the coal would be enough to power 9 light bulbs for a year.

The power plant has 4 tons of coal, with each ton producing 2460 kilowatt hours of electricity, resulting in a total production of 9840 kilowatt hours (4 tons * 2460 kilowatt hours/ton).

To discover if this can power 9 light bulbs for a year, we must first understand the energy consumption of a single bulb. A typical light bulb uses around 60 watts, and there are 8760 hours in a year. Therefore, a light bulb consumes 60 watts * 8760 hours = 525,600 watt-hours or about 526 kilowatt hours in a year.

For 9 light bulbs, the total energy consumption in a year would be 9 * 526 = 4734 kilowatt hours. Therefore, the 9840 kilowatt hours produced by the coal power plant is more than enough to power 9 light bulbs for a year.

Since it's independent you use the formula:

P(A) x P(B) = P(A+B)

(4/5) x P(B) = (1/2)

Make common denominator

(8/10) x P(B) = (5/10)

P(B) = 5/8

If the events are independent, then the value of P(B) will be 5/8.

The chances of an event occurring are defined by probability. Probability has several uses in games, and in business to create probability-based forecasts.

For independent events;

P(A) x P(B) = P(A+B)

(4/5) x P(B) = (1/2)

P(B) =(1/2)×(5/4)

P(B) = 5/8

Answer:

They will meet in 1.866 hours.

Step-by-step explanation:

This is actually quite a simple question once we think about it in a different way.

Instead of thinking of two different planes that are going at two different speeds, think of it like this: the distance between the two planes is decreasing by 670mph (250mph + 420 mph).

Note: miles per hour is equivalent to miles/hour (miles divided by hours or miles over hours)

670m/h becomes our new rate. The rate the distance between the planes is decreasing.

Now, if the distance between them is 1250 miles, how long until they meet?

If we have miles and multiply it by hours/miles, the miles cancel out and you are left with hours.

We have miles (1250) and miles/hours (670). If we multiply these we get units of miles^2 / hours which is not what we want.

we need to multiply 1250 miles by something with the units of hours/miles.

It turns out that the reciprocal of miles/hours is hours/miles

That means we need to multiply 1250 miles by the reciprocal of 670 miles/hours

Note: the reciprocal of a fraction is the fraction flipped around. 1/2 becomes 2/1, reciprocal of 3/5 is 5/3, etc...

the reciprocal of 670 miles/hours = 1/670 miles/hours

Multiplying 1250 miles by 1/670 miles/hours is the SAME as

dividing the number of miles(1250m) by the rate(670m/h)

1250m / 670m/h = 1250m x 1/670 x h/m = 1.866 h = 1.866 hours (the miles cancel out)

To find out how much Cedric would pay for 5 songs, we divide the total cost by the number of songs and then multiply it by 5. Cedric would pay $6.00 for 5 songs.

To find out how much Cedric would pay for 5 songs, we first need to determine the cost per song. From the given information, we can see that the cost of 3 songs is $3.60 and the cost of 4 songs is $4.80. To find the cost per song, we can divide the total cost by the number of songs.

Since the cost per song is the same for both sets of songs, we can conclude that Cedric would pay $1.20 for each song. Therefore, for 5 songs, he would pay 5 x $1.20 = $6.00.
