Step-by-step explanation:

Given speed of Charlotte in kilometer per hour = 9 km/h

We need to find the Charlotte's speed in meter per second.

We know 1 kilometer = 1000 meter

And 1 hour = 3600 seconds.

Plugging those values of km and hour in given speed in km/h, we get

[tex]9\ \frac{km}{h} = 9\times \ \frac{1000m}{3600 seconds}[/tex]

[tex]=\frac{10m}{4s}= 2.5\ m/s[/tex].

Therefore,

Answer:

Speed of Charlotte in a Unit which includes Km and hour [tex]=9 \frac{\text{Km}}{\text{hour}}[/tex]

1 Km=1000 meter

1 hour=60 minutes=3600 seconds

Speed of Charlotte in a Unit which includes meter and second is

                     [tex]=\frac{9 \times 1000}{3600}\frac{\text{meter}}{\text{seconds}}\\\\=\frac{90}{36}\frac{\text{meter}}{\text{seconds}}\\\\=\frac{5}{2}\frac{\text{meter}}{\text{seconds}}[/tex]  

Answer:

first angle is 24

second angle is 108

third angle is 48

all the three angles of the triangle add up to 180

(its a rule)

then 2+9+4=15

180÷15=12

12×2=24

12×9=108

12×4=48

Step-by-step explanation:

i got it right

Given that two rabbits are gray and they represent 1/8 of all rabbits at a pet store, calculated using ratios, it can be inferred that the total number of rabbits is 16.

The question is asking about the total number of rabbits in a pet store given that 1/8 of the total rabbits are gray and there are two gray rabbits. We can use this information to set up a ratio to calculate this.

To find out the total number of rabbits, we can set up a proportion where 2/total rabbits = 1/8. By cross multiplying, we find that 2 * 8 = total rabbits. Therefore, the pet store has 16 rabbits.

Answer:

The measure of angle C is 80 degree.

Step-by-step explanation:

Given information: In ΔABC, ∠A = 40° and ∠B = 60°.

Draw the auxiliary line BD parallel to the line segment AC.

If a transversal line intersects the pair of parallel line, then the alternate interior angles are same.

The angle 1 and 2 are alternate interior angles of angle A and B respectively. Therefore angle 1 is equal to angle A and angle 2 is equal to angle C.

Angle 1,2 and B are supplementary angles because they lie on a straight line, therefore their sum is 180 degree.

[tex]\angle 1+\angle B+\angle 3=180^{\circ}[/tex]

[tex]\angle A+\angle B+\angle =180^{\circ}[/tex]

[tex]40^{\circ}+60^{\circ}+\angle C=180^{\circ}[/tex]

[tex]\angle C=180^{\circ}-100^{\circ}[/tex]

[tex]\angle C=80^{\circ}[/tex]

The angle sum property is another way to solve this problem.

According to the angle sum property, the sum of interior angles of a triangle is 180 degree.

Therefore the measure of angle C is 80 degree.

Answer:

12.5 hours

Step-by-step explanation:

15/6 is 2.5. 2.5 is how many hours per worker. 5 times 2.5 is 12.5 hours

Answer:

1 1/3 feet per year

Step-by-step explanation:

Steps:

1. How many months per year? 12.

2. 12 divided by 3 (number of months) =4

3. multiply 1/3 and 4.

4. Your answer is 4/3 or 1 1/3 feet per year.

The shoreline is eroding at a rate of 4/3 feet per year, which is approximately 1.33 feet per year, calculated by multiplying the 3-month erosion rate of 1/3 foot by 4.

The question is about calculating the annual rate of shoreline erosion given the erosion rate for a specific shorter period. If a shoreline is eroding at a rate of 1/3 foot per 3 months, we can find the yearly erosion rate by multiplying that rate by the number of 3-month periods in a year, which is 4 (since there are 12 months in a year).

To calculate:

Multiply the 3-month erosion rate by 4:

(1/3 foot per 3 months) x 4 (3-month periods in a year) = 4/3 feet per year

Therefore, the shoreline is eroding at a rate of 4/3 feet, or approximately 1.33 feet, per year.

Answer:

Approximately 1.5 cups/hour

Step-by-step explanation:

Divide 214 cups by 145 hours.

(214 cups)/(145 hours) = 1.47586... cups/hour

Remy drinks around 1.47 cups of water in an hour. This was calculated by dividing the total cups (214) by total hours (145).

To solve this question, we need to calculate the rate at which Remy drinks 214 cups of water every 145 hours. This can be done by dividing the total number of cups by the total number of hours.

So, the formula we have is:Cups per hour = Total Cups / Total hours

This gives us:Cups per hour = 214 / 145

After calculating this, you will find that Remy drinks approximately 1.47 cups of water in 1 hour.

Answer:

t = 0.35, t = 5.65

Step-by-step explanation:

You are given h = 30t - 5t^2. Put this in standard form order (ax^2 + bx + c) by switching the two terms.

h = -5t^2 + 30t

Now you want to find all the values of t for which the rocket's height is 10 meters, so your equation will be equal to 10 instead of h, because 10 is the height you are solving for.

10 = -5t^2 + 30t

Make the entire equation equal to 0 by subtracting 10 from both sides.

0 = -5t^2 + 30t - 10

To solve this quadratic equation, the easiest way would be to use the quadratic formula: [tex]\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

Identify your a, b, and c values in the standard form equation (a = -5, b = 30, c = -10) and substitute these values into the quadratic formula.[tex]\frac{-(30)\pm\sqrt{(30)^2-4(-5)(-10)} }{2(-5)} \rightarrow \frac{-30\pm\sqrt{900-200=700} }{-10} \rightarrow \frac{-30\pm\sqrt{700} }{-10}[/tex]

We have (-30 ± sqrt 700)/-10.

Use a calculator to input the two solutions and solve for them; (-30 + sqrt 700)/-10 and (-30 - sqrt 700)/-10.

[tex]\frac{-30+\sqrt{700} }{-10} = 0.35[/tex]

[tex]\frac{-30- \sqrt{700} }{-10} =5.65[/tex]

The quadratic formula is used to solve the equation h = 30t - 5t^2 when h is set to 10 meters, yielding two times at which the rocket's height is 10 meters: approximately 0.59 seconds and 3.41 seconds.

10 = 30t - 5t2

Moving all terms to one side we get:

5t2 - 30t + 10 = 0

To simplify, we divide the entire equation by 5:

t2 - 6t + 2 = 0

Now we can apply the quadratic formula:

t = √ (62 - 4*1*2) )/ (2*1)

Calculating under the square root, we get:

t = (6 √ (36 - 8) )/ 2

t = (6 ± √28) / 2

Thus, the two solutions for t are:

t = (6 + √28) / 2 and t = (6 - √28) / 2

Rounded to the nearest hundredth, the values of t are approximately 0.59 s and 3.41 s. The rocket reaches a height of 10 meters at these two instances during its flight - once when ascending and once when descending.

Answer:

x = 23

Step-by-step explanation:

the sum of the 3 angles in a triangle = 180°

the third angle forms a straight angle with 100°, hence

third angle in triangle = 180° - 100° = 80°

Summing the 3 angles gives

2x + 3 + 80 + 51 = 180

2x + 134 = 180 ( subtract 134 from both sides )

2x = 46 ( divide both sides by 2 )

x = 23

It's a linear function. We need only two points to the plotting of the graph.

Answer:

27% of her net income is her rent payment

Step-by-step explanation:

Net earnings = $740

Lisa spend $200 for rent payment

We need to find out what percent of net earning is her rent payment

Let x be the percentage

x% of net income = rent

x% * 740 = 200

[tex]\frac{x}{100} * 740 = 200[/tex]

Multiply both sides by 1004

740x = 20000

divide both sides by 740

x=27.02702703

Answer:the answer is 75%

Step-by-step explanation:

Martin will earn 75% of his regular hourly rate during his training period, which is calculated by dividing the training hourly rate ($15) by the regular hourly rate ($20) and multiplying by 100%.

To determine what percent of Martin's regular hourly rate he will earn during training, we need to compare his training wage to his regular wage. Martin's regular hourly rate is $20 per hour, and during training, he earns $15 per hour.

The percentage can be calculated using the formula:

Percent Earned During Training = (Training Hourly Rate / Regular Hourly Rate) x 100%

Now, plug in Martin's earnings:

Percent Earned During Training = ($15 / $20) x 100%

Percent Earned During Training = 0.75 x 100%

Percent Earned During Training = 75%

Therefore, Martin will earn 75% of his regular hourly rate during his training period.
