Annie is running a trail that is 4 1/2 miles long. She ran the first 2/3 of the distance. Then the trail became very steep, so she slowed down to a walk. Annie walked for 1/2 of the remaining distance and then ran again for the rest of the way. How far did Annie walk? Write the answer as a simplified fraction.

Answer:

width=60     length=540

Hello, Please consider the following.

Fibonacci numbers are defined as

[tex]u_0=1\\\\u_1=1\\\\u_{n+2}=u_{n+1}+u_{n} \ for \ n\geq 0[/tex]

Step 1 - The proposition is true for n = 1

[tex]GCD(u_2,u_1) ?\\[/tex]

Let's apply Euclidean algorithm

[tex]u_1=1, u_2=2\\\\u_2=2\times u_1+0 = 2 \times 1 +0[/tex]

This is exactly 1 step and [tex]GCD(u_2,u_1) =1[/tex]

Step 2 - We assume that this is true for k, meaning that the Euclidean algorithm takes precisely k steps to prove that [tex]GCD(u_{k+1},u_{k})=1[/tex]

[tex]u_{k+2}=u_{k+1}+u_k \ and \ 0 < u_k < u_{k+1}[/tex]

So, the first step of the algorithm is

[tex]u_{k+2}=u_{k+1}\times 1 +u_{k}[/tex]

And from now, we need to find [tex]GCD(u_{k+1},u_k)[/tex] which is 1 and takes k steps, by induction Hypothesis. Therefore, it takes k + 1 steps to find [tex]GCD(u_{k+2},u_{k+1})=1[/tex]

Step 3 - Conclusion

We have just proved that the Euclidean algorithm takes precisely n steps to prove that [tex]GCD(u_{n+1},u_{n})=1[/tex]

He starts to ride at 3:27 p.m.

85 minutes -> hours = 1 h 25 minutes (85/60 = 1 with 25 of rest)

3:27 + 1 h 25 min = h. 4:52

between 4:52 and 5:45 =>

5 hours 45 min - 4 hours 52 minutes =

4h 105 min ( 1h = 60min ) - 4h 52 min =

0h 53min

Payton has 53 minutes

Answer:

53 minutes

Step-by-step explanation:

Payton leaves at 3:27 p.m. and rides for 85 minutes.  When she has finished, the time will be 3:27 + 0:85, or

                           3:27 + 1:25, since 1 hr = 60 min

                             4:52 p.m.

Dinner will be at 5:45 p.m.  That means Payton will have (5:45 - 4:52) hours until dinner:  Borrowing 60 minutes from 5:45, we get

4:105 - 4:52 = 0:53.  That's 53 minutes to while away before dinner.

Answer:

when say your expenses are $400 a month but your income is only $350 a month that is -$50 every month so in that case you aren't getting a positive cash flow (which would be making more money than your expenses) So you must be getting a negative cash flow in which you are losing money and going into debt.

C. selling a car and making a profit of $3,000

Step-by-step explanation:

An example of earning income from capital gains is selling a car and making a profit of $3,000 which the correct answer would be an option (C).

Gross capital formation for a unit or sector is calculated using the total value of gross fixed capital growth, changes in inventories, and asset acquisitions with fewer asset disposals.

As we know, from the meaning of capital gain:

When a capital asset is sold, the rise in value is known as a capital gain.

Selling a car and getting $3,000 in profit is one example of making money through capital gains.

An example of earning income from capital gains is selling a car and making a profit of $3,000

Hence, the answer would be option (C).

Answer:

D

Step-by-step explanation:

Let a be the number of TV sets that weight 30 kg and let b be the number of TV sets that weigh 50 kg.

So, all together, they have a total weight of 880. In other words:

[tex]30a+50b=880[/tex]

And, there are 20 TV sets all together. Thus:

[tex]a+b=20[/tex]

This is a system of equations. Solve by substitution. Subtract b from both sides in the second equation:

[tex]a+b=20\\a=20-b[/tex]

Substitute this into the first:

[tex]30a+50b=880\\30(20-b)+50b=880[/tex]

Distribute:

[tex]600-30b+50b=880[/tex]

Subtract 600 from both sides:

[tex]-30b+50b=280[/tex]

Combine like terms:

[tex]20b=280[/tex]

Divide both sides by 20:

[tex]b=14[/tex]

So, there are 14 TV sets that weight 50 kg.

Plug this in for the second equation to solve for a:

[tex]a+b=20[/tex]

Plug in 14 for b:

[tex]a+14=20[/tex]

Subtract 14 from both sides:

[tex]a=6[/tex]

Therefore, there are 6 TV sets that weigh 30 kg and 14 TV sets that weigh 50 kg.

Our answer is D :)

Step-by-step explanation:

Total number of T..V sets we have 20

Let x be the number of T.V sets that weigh 30 kg and y be the no. of sets that weigh 50 kg

When we add all we get a total of 880

[tex]\blue\star[/tex] 30a + 50b = 880

It is given to us that

[tex]\blue\star[/tex]a + b = 20. eq 1

[tex]\blue\star[/tex]a = 20-b

Put the value of a in ist equation we get,

[tex]\blue\star[/tex]30(20-b) + 50b =880

[tex]\blue\star[/tex]600 - 30b+50b = 880

[tex]\blue\star[/tex]600 + 20b = 880

[tex]\blue\star[/tex]20b = 280

[tex]\blue\star[/tex] b = 14

so there are 14 T.V sets that weigh 50 kg

put it in eq 1 we get

[tex]\blue\star[/tex] a + b =20

[tex]\blue\star[/tex]a + 14 = 20

[tex]\blue\star[/tex]a = 6

Answer:

A. 5 < AC < 10

Step-by-step explanation:

We are given the ∆ABC

To solve for the sides of ∆ABC , we make use of Pythagoras Theorem

Pythagoras Theorem states that:

AB² = AC² + BC²

Where AB = Longest side, hence its length is always more that AC and BC.

In the above Question, we are given the values of AB and BC

AB = 10

BC = 5

Inputting these values into the Pythagoras Theorem,

10² = AC² + 5²

100 = AC² + 25

AC² = 100 - 25

AC² = 75

AC = √75

AC = 8.6602540378

According to the above calculation, we can see that the expression that is always true = Option A "5 < AC < 10"

Answer:

Annie walked 1 11/12 miles

Step-by-step explanation:

Trail= 4 1/2 miles

Annie ran the first 2/3 miles

Remaining miles= Total miles - Miles covered first

= 4 1/2 - 2/3

= 9/2 - 2/3

= 27-4 / 6

= 23/6 miles

Remaining miles = 23/6 miles

Annie walked for 1/2 of the remaining distance

1/2 of the remaining miles= 1/2 × 23/6

=23 / 12

= 1 11/12

Annie walked 1 11/12 miles

Answer:

We need to evaluate this: [(-16)+4] / [(-2)+5]

First, we do the brackets:

[(-16)+4] = -16 + 4 = -12

[(-2) + 5] = -2 + 5 = 3

Now, we only need to divide, as we have calculated both brackets:

-12/3 = -4

(Remember that when dividing a negative number by a positive one, we always obtain a negative)

So the result is -4

[tex] t = 4x [/tex]

Step-by-step explanation:

We are given that in 1 month, Jessica takes 4 business trips. Take 4 as our coefficient or constant.

Let t be the total number of business trips Jessica has taken.

For 1 month, 4 trips are taken.

For x months, total business trips taken will be expressed as,

[tex] t = 4x [/tex]

Let's say for example, we have 5 months in a row, i.e. x = 5. Total business trips taken by Jessica can be gotten by simply plugging in the value of x.

[tex] t = 4(5) = 20 trips [/tex]

In 5 months in a row, Jessica takes 20 business trips.

-3 x (-5) = 15

-2 x (-1) = 2

6 x 6 = 36

Can you multiply it all out? Yes. Did you need to? No. That was just to prove that the first choice is correct.

All you have to know to answer this is that:

positive * positive = positive; + * + = +

negative * negative = negative; - * - = +

positive * negative (or negative * positive; remember that the order of the numbers you're multiplying does not matter) = negative; + * - = - or - * + = -

Or if you learn better in words:

If two factors have the same sign, the answer is positive.

If two factors have different signs, like if one is positive and the other is negative, then the answer is negative.

Answer:

58

Step-by-step explanation:

We can use the Pythagorean theorem to find the area of the square for the third side.

The equation for the Pythagorean theorem is

a^2 + b^2 = c^2

where a and b are the lengths of the two legs of the triangle, and c is the length of the hypotenuse.

a^2 + b^2 = c^2

3^2+7^2=x^2

9+49=x^2

58=x^2
The area of the square for the third side of the triangle is 58 units^2 squared.

Answer:

Diverges

Step-by-step explanation:

since the value of  P = 5/6 < 1  the p-series diverges

summation of 1/n^5/6  at n = 1 and infinity

attached below is the detailed solution using Theorem 9.11 to determine the convergence or divergence of the p-series

The value of the p in the p-series is less than one. Then the p-series is a divergence.

It is an infinite type of series.

The p-series is given below.

[tex]1 + \dfrac{1}{\sqrt[6]{32} } +\dfrac{1}{\sqrt[6]{243} }+\dfrac{1}{\sqrt[6]{1024} }+\dfrac{1}{\sqrt[6]{3125} }[/tex]

The series can be written as

[tex]\dfrac{1}{1^{5/6}}+\dfrac{1}{2^{5/6}}+\dfrac{1}{3^{5/6}}+\dfrac{1}{4^{5/6}}+\dfrac{1}{5^{5/6}}[/tex]

Then the sum will be

[tex]\rm \Rightarrow \Sigma _{n=0} ^{\infty} \dfrac{1}{n^{5/6}} \\\\\\\Rightarrow P = \dfrac{5}{6} < 1[/tex]

Since the value of the p is <1. Then the series is divergence.
