Answer:

5000

Step-by-step explanation:

X = money borrowed

supposing that the 6% is a yearly interest, every year she has to add 6% of X to the original amount X

we can write this as

X + 10*6/100X = 8000

X + 6/10 X = 8000

X + 3/5X = 8000

8/5X = 8000

X = 8000*5/8 = 5000

In the Northern Hemisphere, dolphins swim predominantly in a counterclockwise direction while sleeping. A group of researchers wanted to know whether the same was true for dolphins in the southern hemisphere. They watched 8 sleeping dolphins and found that they swam in a clockwise direction while sleeping the following percentages of time. Assume that this is a random sample and that this variable has a normal distribution in the population. Given the following observations of percentages of time spent swimming clockwise, the mean is (FILL IN THE BLANK) and the median is (FILL IN THE BLANK)

Express your answers as percentages to one decimal place.

77.7, 84.8, 79.4, 84.0, 99.6, 93.6, 89.4, 97.2

Mean percentage = 88.57 %

Median = 87.1

Solution:

Given that,

Given the following observations of percentages of time spent swimming clockwise

77.7, 84.8, 79.4, 84.0, 99.6, 93.6, 89.4, 97.2

Total observations = 8

Sum of observations = 77.7+ 84.8 + 79.4 + 84.0 + 99.6 + 93.6 + 89.4 + 97.2

Sum of observations = 705.7

Mean is given as:

Mean percentage:

Find median

Median is the middle value in data set

Arrange in ascending order

77.7, 79.4, 84.0, 84.8, 89.4, 93.6, 97.2, 99.6

Median = 87.1

10. What's 15/45 written as a fraction in simplest form? O A. 15/3

OB. 13

O c. /

O D.315

Answer:

1/3

Step-by-step explanation:

The GCF is 15. 15 divided by 15 is 1, and 45 divided by 15 is 3.

Could you perhaps mark my answer as brainliest?

since 3 is a common factor in both 15 and 45 we can do:

15/3 = 5

45/3 = 15

to get 5/15

now 5 is a common factor in both 5 and 15 so we can do:

5/5 = 1

15/5 = 3

so the simplest version is 1/3

14x+2y+−216x+−144y

step two:combine like terms

14x+2y+−216x+−144y

(14x+−216x)+(2y+−144y)

What is the answer to 7(p - 14) = 42 ?

Answer:

p=20

Step-by-step explanation:

7(p-14)=42

step one : distribute the 7 inside the parentheses

7p-98=42

step two: get 98 to the other side of the equal sign

7p=140

step 3: get p by itself

p=20

Your answer will be p=21.42

On a no wind day, an airplane is flying 2000 miles round trip from Chicago to Boston and back to Chicago with a constant speed of 500 mph. About how long would it take to fly the same round trip if there is a wind speed of 100 mph from Chicago to Boston during the whole round trip flight?

Answer:

It would take the plane about 4.17 hours to fly the whole round trip.

Step-by-step explanation:

Assuming that the distance from Chicago to Boston is 2000/2 = 1000 miles.

Since the wind is blowing from Chicago to Boston, when the plane is traveling to Boston, the velocity of the wind adds to the its velocity:

;

therefore, the time it takes for the plane to go from Chicago to Boston is

Now, as the plane flies back from Boston to Chicago, the wind is blowing opposite the direction of its movement; therefore, the wind's velocity subtracts from the velocity of the plane:

and the time taken during the trip is

Therefore, the total time taken during the whole round trip is

Therefore, on the windy day, it would take the plane 4.17 hours to fly the whole round trip

Let () = x + 6 and () = 5x − 2. Find the solution to the equation () = () by sketching the functions.

f(x) = g(x) at x=2.

Step-by-step explanation:

We have, f(x) = x + 6 & g(x) = 5x - 2. Let's sketch graph step by step :

for f(x):

f(x)= x is a straight line passing through origin. Then , shift graph by 6 units in right so it be comes f(x) = x + 6 .

For g(x) :

g(x) = x is a straight line passing through origin. Then , expansion of graph by 5 units so it becomes g(x) = 5x . Then , shift the graph by 2 units to left so final equation becomes g(x) = 5x - 2.

Now, on comparing graph of both f(x) & g(x) we see that f(x) cuts g(x) at one and only point at x = 2. Also, for x = 2 , f(x) = g(x). ∴f(x) = g(x) at x=2.

Answer:

would be the correct statement.

Step-by-step explanation:

As we know that

Average rate of change = Change in output / Change in input

= Δy / Δx

As the average rate of change of g(x) between x = 4 and x = 7 is 5/6.

so

Therefore, would be the correct statement.

Which one is greater than 1 3/24 or 1 2/6

Answer:

1 2/6

Step-by-step explanation:

1 3/24 is simplified to 1 1/8

1 2/6 is simplified to 1 1/3

since the denominator in 1 1/3 is less and the numerators are the same 1 2/6 is greater.

Answer:1 2/6

Step-by-step explanation:

From the above:

3/24 = 0.2

1 2/6 = 14/6 = 2.33

P varies directly as I. If P is 0.5 when I is 4, find P when I is 6

Answer:

P = 0.75

Step-by-step explanation:

Given that P varies directly as I then the equation relating thenm is

P = kI ← k is the constant of variation

To find k use the condition P = 0.5 when I = 4, thus

k = = = 0.125

P = 0.125I ← equation of variation

When I = 6, then

P = 0.125 × 6 = 0.75

Each week, Darin's Lawn Service mows 90 lawns in 45 hours at a housing complex. The lawns in the complex are the same size. At this rate, how many hours will it take Darin to mow 12 lawns?

The number of hours it takes Darin to mow 12 lawns is 24 hours.

Given that, Each week, Darin's Lawn Service mows 90 lawns in 45 hours at a housing complex.

What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Here, the rate at which Darin's Lawn Service mows

= 90/45

= 2 lawns/hour

Now, number hours to mow 12 lawns

= 12 ×2

= 24 hours

Therefore, the number of hours it takes Darin to mow 12 lawns is 24 hours.

Y = -2/3x + c

6 = -2/3 + c

6 and 2/3 = c

Therefore: y = -2/3x + 6 and 2/3

6 = -2/3 + c

6 and 2/3 = c

Therefore: y = -2/3x + 6 and 2/3
