Answer:

Arithmetic sequence

Step-by-step explanation:

In an arithmetic sequence, the next term on the sequence is obtained by adding a certain value to the first term. This term that is added is uniform throughout the sequence. Once this term is added to the preceding term, the next term of the sequence is obtained. This term that is thus added is known as the common difference of the arithmetic sequence.

So the arithmetic sequence obtained by adding 4 starting from 2 is; 2, 6, 10, 14 .........

The function f(x) = 2x 26 represents the distance a flock of birds travels in in miles. The function g(x) = x − 1 represents the

nydimaria [60]

Speed is the ratio of distance and time. When we divide f(x) by g(x) we will get the speed of the flock that is 9 miles/hour.

<h3>What is speed?</h3>

Speed can be defined as the rate of change in the position of an object. It is given as,

$Speed = \dfrac{Distance}{Time}$

Given to us

Distance traveled, f(x) = 2x+26

Time, g(x) = x − 1

As we know that the ratio of distance and time is equal to the speed of the object. Since the distance traveled by the flock of birds is given also, the time needed for them to travel the distance is also given.

We need to find f divided by g of 5, which is the speed of the flock,

$Speed = \dfrac{Distance}{Time} = \dfrac{f(x)}{g(x)}$

$Speed = \dfrac{f(x)}{g(x)} = \dfrac{2x +26}{x-1}$

$Speed = \dfrac{f(5)}{g(5)} = \dfrac{2(5) +26}{(5)-1}\\\\Speed = 9 \rm\ miles/ hour$

Hence, when we divide f(x) by g(x) we will get the speed of the flock that is 9 miles/hour.

This problem is taken from the delightful book "Problems for Mathematicians, Young and Old" by Paul R. Halmos. Suppose that 681

aleksley [76]

Answer:

680 games

Step-by-step explanation:

Suppose that 681 tennis players want to play an elimination tournament.

1st round:

One of 681 players, chosen at random, sits out that round and 680 players play. There will be 340 winners plus one player which sits - 341 players for the next round and 340 games

2nd round:

There will be 170 winners plus one player which sits - 171 players for the next round and 170 games

3rd round:

There will be 85 winners plus one player which sits - 86 players for the next round and 85 games

4th round:

There will be 43 winners - 43 players for the next round and 43 games

5th round:

There will be 21 winners plus one player which sits - 22 players for the next round and 21 games

6th round:

There will be 11 winners - 11 players for the next round and 11 games

7th round:

There will be 5 winners plus one player which sits - 6 players for the next round and 5 games

8th round:

There will be 3 winners - 3 players for the next round and 3 games

9th round:

There will be 1 winner plus one player which sits - 2 players for the next round and 1 game

10th round - final:

1 champion and 1 game.

In total,

340 + 170 + 85 + 43 + 21 + 11 + 5 + 3 + 1 + 1 = 680 games

I need help ASAP middle school work.

Arturiano [62]

Answer:

Step-by-step explanation:

For 11 1/2 gallons, he paid $36.80.

We need to find the cost per gallon.

First, converting 11 1/2 gallons to decimal, it is:

1/2 = 0.5

So, 11 1/2 is 11.5 gallons

So, Cost Per Gallon (last week) = $\frac{36.80}{11.5}=3.2$

There is 5% increase on this $3.20 per gallon. We find 5% of 3.2 and add it to 3.2 to find this week's cost per gallon.

5% = 5/100 = 0.05

0.05 * 3.20 = 0.16

So,

3.20 + 0.16 = $3.36 per gallon

Cost Per Gallon (this week) = $3.36

To buy 9 1/4 gallons it would take:

$3.36*9.25=31.08$

Note: 1/4 = 0.25, so 9 1/4 = 9.25

It would cost $31.08 to buy 9.25 gallons this week

Correct answer is B
