Charolette is running at a rate of 9km/h. What is Charolette’s speed in m/s?

Answers

Answer 1

Answer:

seems like the main concept being tested here is unit conversion.

First, let's look at converting kilometers to meters. In the metric system, the prefix "kilo" means 1000. So,

1 kilometer = 1000 meters.

Then, let's look at converting from hours to seconds. As you may know, there are 60 minutes in an hour, and 60 seconds in a minute. So, in 1 hour there are

1 hour*(60 minutes/hour)*(60 seconds/minute) = 3600 seconds.

So, we can use these unit conversion factors to solve your question. Let's convert the units!

9 km/hr = 9 km/hr * (1000 m/km) * (1 hr/ 3600 sec) = 2.5 m/s

Hope this helps!

Solve. 8 - 2d = c 4c + 3d = 2 c=4 d = -6 C=-4 d = 6 C=4 d = 6 C=-4 d = -6

Answers

Answer:

c = -4 d = 6

Step-by-step explanation:

8 - 2d = c 4c + 3d = 2

4(8 - 2d) + 3d = 2

32 - 8d + 3d = 2

32 - 5d = 2

-5d = -30

d = 6

8 - 2(6) = c

8 - 12 = -4 = c

Gin bakes a perfectly circular pizza with a diameter of 10 inches, and he selst for $0.20 per square inch What is the cost for
the entire pizza? Express your answer to the nearest whole ola

Plz help

Answers

Answer:

$15.70

Step-by-step explanation:

The formula for a circle's area is πr^2 and so the radius is 10/2 or 5. 3.14*5^2 is 78.54. Multiply this by $0.20 to get the total cost of the pizza. The total cost is $15.70.

The equation y = 1125(1.034)" can be used to approximate the number of cell phone users
who live in a certain city over time, where a represents the number of years after 2000.
Which of the following statements is true?
A
the rate of growth is 34%
B
there were 1125 cell phone users in 2000.
С
the rate of decay is 3.4%
D
In the year 2005, there were more than 1350 cell phone users.

Answers

Answer: B

there were 1125 cell phone users in 2000.

Step-by-step explanation:

The initial number of cell phone users is the front coefficient that is then multiplied by the growth factor.

So the initial number of cell phone users in 2000 was 1125.

He answer should be b because it mentions number of years after 2000 in the question that’s the answer that seems logical to me

James, Ryan and Jill share £120 in the ratio 3:2:1.
Find out how much each person recieves.

Answers

Answer:

James = £60, Ryan = £40 and Jill = £20

Step-by-step explanation:

James - 3, Ryan - 2 and Jill - 1

3 + 2 + 1 = 6

£120 / 6 = 20

Times 20 by each of the three numbers (3, 2 and 1)

3 x 20 = £60 (James)

2 x 20 = £40 (Ryan)

1 x 20 = £20 (Jill)

Answer:

James gets £60

Ryan gets £40

Jill gets £20

Step-by-step explanation:

Add up the ratio which would be 6 then divide it by the original sum which is £120 so the answer would be 20. You would then multiply 20 by each number so 20x3= 60. 20x2= 40. 20x1=20

All these should add up to your original sum and if they do you know you've done it right!

A random sample of 10 subjects have weights with a standard deviation of 11.0995 kg. What is the variance of their weights?

Answers

Answer:

[tex]123.19890025 kg^2[/tex]

Step-by-step explanation:

We are given that

Standard deviation, s=11.0995 kg

Sample size, n=10

We have to find the variance of their weights.

We know that

Variance=[tex](standard\;deviation)^2[/tex]

Using the formula

The variance of their weights

=[tex](11.0995)^2[/tex]

=[tex]123.19890025 kg^2[/tex]

Hence, the variance of their weights=[tex]123.19890025 kg^2[/tex]

12 + 5/3 b + 1 1 − 18 = 20

Answers

Answer: b = 9

Step-by-step explanation:

Given

12 + 5/3b + 11 - 18 = 20

Combine like terms

(12 + 11 - 18) + 5/3b = 20

5 + 5/3b = 20

Subtract 5 on both sides

5 + 5/3b - 5 = 20 - 5

5/3b = 15

Divide 5/3 on both sides

5/3b / (5/3) = 15 / (5/3)

b = 9

Trevor has an investment worth $6,774.50. He made his only deposit in it 22 years ago. Given that the investment yields 2.7% simple interest annually, how big was the initial deposit?

a. $2,524.50
b. $4,024.03
c. $4,250.00
d. $11,404.88

Answers

Answer:

First, converting R percent to r a decimal

r = R/100 = 2.7%/100 = 0.027 per year.

Solving our equation:

P = 6774.5 / ( 1 + (0.027 × 22)) = 4250P = $4,250.00

The principal investment required to get a total amount, principal plus interest, of $6,774.50 from simple interest at a rate of 2.7% per year for 22 years is $4,250.00I do exams and quizzes if your interested!

The initial deposit amount is $4,250.00.

Given that,

The worth of an investment is $6774.50The time period is 22 years. The rate of interest is 2.7%.

Based on the above information, the calculation is as follows:

We know that

[tex]SI =P\times R\times T\\\\SI = P\times 2.7\% \times 22\\\\SI = 0.594P[/tex]

Now

Investment worth = P + SI

= P + 0.594P

= 1.594P

So,

1.594P = 6774.50

P = $4,250

Therefore we can conclude that the initial deposit amount is $4,250.00.

find the length of side x in simplest radical form with a rational denominator 60 30 x 2

Answers

Answer:

x = √3

Step-by-step explanation:

Looking at the given triangle,

x is the adjacent side while 2 represents the hypotenuse side.

Now, from trigonometric ratios, we know that;

Adjacent/hypotenuse = cos θ

The angle here will be 30°

Thus;

x/2 = cos 30°

We are told to find x in simplest radical form with a rational denominator.

Thus means we will use the surf value of the angle.

cos 30° in surd form = (√3)/2

Thus;

x/2 = (√3)/2

x = 2 × (√3)/2

x = (√3)/1

x = √3
