Step-by-step explanation:

Initial Length of the rope (r) = 12 m

Final length of the rope (R) = 23 m

[tex]Additional\ area\ acquired\ = Final Area- Initial Area\\=\pi R^2- \pi r^2\\=\pi (R^2-r^2)\\=\pi (23^2-12^2)\\=\pi (529-144)\\=\pi (385)\\=385\pi \\\\As\ \pi = \frac{22}{7} \\\\Hence,\\385\pi \\=385 * \frac{22}{7} \\=55*22\\=1210 m^2[/tex]

Answer:

  18.64 miles

Step-by-step explanation:

There are 1.609344 km per mile, so the distance traveled in 1 second is ...

  (30 km)(1 mi)/(1.609344 km) ≈ 18.64 mi

The Earth travels around the Sun at the rate of about 18.64 miles per second.

Answer:

18.64 if rounded

Step-by-step explanation:

First you need to know how many miles is 1 kilometer. That would be approximately 0.62137 miles. Multiply this by 3 and you would get 1.86411. Now multiply this by 10 to make it 30 kilometers worth of miles and not 3 kilometers. You would get 18.6411 which rounded to the hundredths place would be 18.64.

Answer:

The image of point (1,-4) after a rotation of 180° counter clockwise about the origin is: (-1,4)

Step-by-step explanation:

Rotation means that a point is being moved in clockwise or counterclockwise direction with some angle.

The rotation can be done in 90, 180, 270 degrees.

Given point is:

(1,-4)

When a point (x,y) is rotated 180° counter clockwise its coordinates become (-x,-y) the negative of original point.

So for the given point the coordinates will become (-1,4)

Hence,

The image of point (1,-4) after a rotation of 180° counter clockwise about the origin is: (-1,4)

Step-by-step explanation:

1) rate = ( 1484 - 1708) ÷ ( 11 - 7) = - 56 m/ s

2) rate × 13 = - 56 × 13 = - 728 m per 13 s

3) rate = - 56

t = 24 s

d = - 56 × 24 = 1344 m

whole distance = 2100

7 × 56 = 392

and he flay till 1708 then whole distance = 392 + 1708

so the remaining distance between him and her

2100 - 1344 = 756 m

Answer:

The answer is 6/8

Step-by-step explanation:

6/8 is the only logical answer because you need to have an answer that is less than one, 8/6 evens out to 1 1/3, 6/2 evens out to 3, and 8/4 evens out to 2. 6/8 is the only fraction that is less than one.

Answer:

its 6/8

Answer:

Value of x = 12 unit

Step-by-step explanation:

Given:

tw = 3x+5

wx = 10

tx = 5x-9

Find:

Value of x

Computation:

tw + wx = tx

3x + 5 + 10 = 5x - 9

3x + 15 = 5x - 9

2x = 24

x = 12

Value of x = 12 unit

Answer:

The constant of proportionality is 40 sour patch kids per day

Step-by-step explanation:

Here, we want to find the constant of proportionality

From the question, we are told that he eats 20 sour patch kids in half a day

what this mean is that he will eat 20 * 2 = 40 sour patch kids in a day

The constant of proportionality is thus 40 sour patch kids per day

Answer:

Answer:

Step-by-step explanat

Given=F(0) = 3 and f(1) = 15.

So f(X)=12x+3

When X=0, f(0)=12x0+3=3

When X=1, f(1) = 12x1+3= 15

So f(X)=12x+3 is the solution o

Answer:

9 times

Step-by-step explanation:

A dog snores 1/3 of an hour

60 minutes = 1 hour

Hence,

1/3 of 60 minutes = 20 minutes

Hence, every 20 minutes, the dog snores

This means in 1 hour, the dog snores 3 times

The dog slept for 3 hours

Hence,

1 hour = 3 times

3 hours = x

Cross. Multiply

x = 3 × 3 times

x = 9 times

The dog snores 9 times

Answer:

Gina—her standardized score is higher than Colleen’s.

Step-by-step explanation:

Until the scale was changed in 1995, SAT scores were based on a scale set many years ago.

We solve this question using z score formula also know as standardized score formula which is given as:

z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.

For Gina

Gina took the SAT in 1994 and scored 500 on the Math test.

For Math scores, the mean under the old scale in the 1990s was 470 and the standard deviation was 110.

x = 500

μ = 470

σ = 110

Hence, the z score is given as:

z = 500 - 470/110

z = 0.27273

Gina's z or standardized score is 0.27273

For Colleen

Her cousin Colleen took the SAT in 2013 and scored 530 on the Math test.

In 2013 the mean was 515 and the standard deviation was 116.

x = 530

μ = 515

σ = 116

Hence, the z score is given as:

z = 530 - 515/116

z = 0.12931

Colleen's z or standardized score is 0.12931

The person who did better relative to their peers is Gina and this is because her standardized score is higher than Colleen’s.

Given:

Charges for rental card = $10

Charges for movie = $2 per movie

To find:

The linear equation for given situation and find the cost to rent 6 movies.

Solution:

Let y be the total cost for x number of movies.

Cost of one movie = $2

Cost of x movies = $2x

Total cost = Charges for rental card + Charges for x movies

[tex]y=10+2x[/tex]

Put x=6 to find the cost of 6 movies.

[tex]y=10+2(6)[/tex]

[tex]y=10+12[/tex]

[tex]y=22[/tex]

Therefore, the total cost for a new customer to rent 6 movies is $22.

Answer:

a = 43°

Step-by-step explanation:

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

Sum the 3 angles and equate to 180, that is

a + 8 + 2a + 43 = 180

3a + 51 = 180 ( subtract 51 from both sides )

3a = 129 ( divide both sides by 3 )

a = 43
