The difference between their average hiking rates is 0.51 miles/hour.

Given that, it took Lannie 1.9 hours to hike Ranger Cove Trail. It took Ava 4 hours to hike Mohawk Trail.

The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.

Using speed =Distance/Time

Here, Ranger Cove distance =4.8 miles and time =1.9 hours

Now, rate =4.2/1.9

= 2.21 miles/hour

Mohawk Trail distance =6.8 miles and time =4 hours

Now, rate =6.8/4

= 1.7 miles/hour

The difference between their average hiking rates

= 2.21-1.7

= 0.51 miles/hour

Hence, the difference between their average hiking rates is 0.51 miles/hour.

What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

In ΔSTU, s = 250 inches, ∠U=17° and ∠S=52°.

Now,

Since, In ΔSTU, s = 250 inches, ∠U=17° and ∠S=52°.

Hence, ∠ T = 180 - (17 + 52)

∠ T = 180 - 69

∠ T = 111°

Now, We use the sin rule as;

⇒ t / sint = s / sin s

⇒ t / sin 111° = 250 / sin 52

⇒ t = sin 111° × 250 / sin 52

⇒ t = 0.93 × 250 / 0.79

⇒ t = 294.30 inches.

Thus, The length of t will be;

The complete table of values of the linear equation y = -3x - 4 is

x     y

-1     -1

0     -4

From the question, we have the following parameters that can be used in our computation:

y = -3x - 4

Also, we have the following table of values

x     y

-1

0

The above table of values mean that the x values are

x = -1, 0 and 1

Substitute x = -1, 0 and 1 in the equation y = -3x - 4

So, we have the following representation

When x = -1

y = -3(-1) - 4 = -1

When x = 0

y = -3(0) - 4 = -4

When x = 1

y = -3(1) - 4 = -7

So, we have the following ordered pairs

(-1, -1), (0, -4) and (1, -7)

When represented on the table of values, we have

The free fall speed of a parachutist can exceed 216 kilometres per hour. During his 20 seconds of free fall, the parachutist will plunge 1960 metres.

Every time an object is subject to a net force that is greater than zero, acceleration happens. You can experience it when riding down a steep hill on your sled in the snow or when you slightly accelerate or decelerate in an elevator. Furthermore, we know that the universe as a whole is expanding at an even faster rate because to the general theory of relativity. This implies that the distance between two places is always enlarging, yet we are oblivious to this on a daily basis because every scale in the universe also expands.

During free only acceleration due to gravity(g) acts on the parachutist. Assuming acceleration due to gravity is positive i.e. g=9.8m/s² .

For conversion we know that

1 km = 1000 m and

Step-by-step explanation:

3(2x-5)=9(10-x)

6x-15=90-9×

6x+9x=90+15

15x=105

×=7

Answer:

x = 7

Step-by-step explanation:

1. Distribute

3(2x - 5) = 9(10 - x)

6x - 15 = 9(10 - x)

2. Rearrange Terms

6x - 15 = 9(10 - x)

6x - 15 = 9(-x + 10)

3. Distribute

6x - 15 = 9(-x + 10)

6x - 15 = -9x + 90

4. Add 15 to both sides

6x - 15 = -9x + 90

6x - 15 + 15 = -9x  + 90 + 15

5. Simplify

Add the numbers:

6x - 15 + 15 = -9x + 90 + 15

6x = -9x + 90 + 15

Add the numbers:

6x = -9x + 90 + 15

6x = -9x + 105

6. Add 9x to both sides

6x = -9x + 105

6x + 9x = -9x + 105 + 9x

7. Simplify

Combine like terms:

6x + 9x = -9x + 105 + 9x

15x = -9x + 105 + 9x

Combine like terms:

15x = -9x + 105 + 9x

15x = 105

8. Divide both sides by the same factor

15x = 105

15x/15 = 105/15

9. Simplify

Cancel terms that are in both the numerator and denominator:

15x/15 = 105/15

x = 105/15

Divide the numbers:

x = 105/15

The year in which Gert will find that she has doubled her money is year 20.

Simple interest is when the interest earned on an investment increases linearly each year.

The formula that can be used to determine simple interest is:

Simple interest = amount invested x duration of the investment x interest rate.

When the amount of money in the account is double what it is now, it means that the interest earned would be $2000 and the value of the account would $4000 (2000 + 2000).

Year when investment would have doubled  = simple interest / (amount invested x interest rate)

Year when investment would have doubled  = $2000 / (0.05 x 2000)

An exponential function is a mathematical function, which is used in many real-world situations. It is mainly used to find the exponential decay or exponential growth or to compute investments, model populations and so on.

The No of bacteria left at a particular time t is given as N(t)= Noe^-kt

where No= initial number of bacteria

k= decay constant and t = time

after 13 minutes

630= 700e^-13k

divide both sides by 700

630/700= e^-13k

0.9= e^-13k

ln0.9= -13k

k= ln0.9/-13 = -0.1054/-13 = 0.0081

time for 20 bacteria to be left =

20= 700e^-0.0081t

= 20/700=e^-0.0081t

0.0286= e^-0.0081t

ln0.0286= -0.0081t

-3.554= -0.0081t

divide both sides by -0.0081

t= -3.554/-0.0081= 439 minutes ( nearest minutes)

Cindy's monthly payment of $609.63 will cost her $29,262.24 in 4 years at a 4% APR.

The total cost that Cindy will spend on the car which costs $27,000 is computed by multiplying the monthly payment by 48 months (the payment period).

The monthly payment can be determined using an online finance calculator that compounds the interest rate monthly for four years.

Cost of car = $27,000

Annual Percentage Rate (APR) = 4%

Payment period = 4 years (monthly)

N (# of periods) = 48 months (4 years x 12)

I/Y (Interest per year) = 4%

PV (Present Value) = $27,000

FV (Future Value) = $0

Results:

PMT = $609.63

Sum of all periodic payments = $29,262.24

Total Interest = $2,262.45

Thus, Cindy will spend $29,262.24 for a car that costs $27,000, if she repays monthly for 4 years.
