8. Anneke is swimming the 500-meter freestyle, which consists of swimming the length of a pool 20 times. If Anneke averages 26.4 seconds per length of pool, write an equation that could be used to determine the number of meters (m) Anneke has left in the event after swimming for s seconds.

Answers

Answer 1

Answer:

Anneke will swim 20 lengths in the 500-meter event,

which means each length of the pool is = 500/20

= 25m

also since Anneke can swim one length in 26.4 seconds on average

hence her average speed is = 25/26.4 m/s

hence after a seconds,

the distance traveled = 25s/26.4 meter

thus, the remaining distance Anneke need to travel is:

m = 500 - (25s/26.4)

The capacity of this coliseum is 1600

The correct option is (C)

What is fraction?

A fraction is a part of a whole. In arithmetic, the number is expressed as a quotient, in which the numerator is divided by the denominator. In a simple fraction, both are integers. A complex fraction has a fraction in the numerator or denominator.

Given:

Total people attended the Coliseum= 1200

let he capacity be x

3/4*x= 1200

x= 1200*4/3

Yes , the series is an arithmetic sequence of common difference 2

What is Arithmetic Progression?

An arithmetic progression is a sequence of numbers in which each term is derived from the preceding term by adding or subtracting a fixed number called the common difference "d"

The general form of an Arithmetic Progression is a, a + d, a + 2d, a + 3d and so on. Thus nth term of an AP series is Tn = a + (n - 1) d, where Tₙ = nth term and a = first term. Here d = common difference = Tₙ - Tₙ₋₁

Sum of first n terms of an AP: Sₙ = ( n/2 ) [ 2a + ( n- 1 ) d ]

Given data ,

Let the number of terms n = 20

The number of tiles in the first row = 10 tiles

The number of tiles in the second row = 2 more than first row

The number of tiles in the second row = 12 tiles

The number of tiles in the third row = 14 tiles

So , the sequence will be , 10 , 12 , 14 , 16 ...

The number of terms n = 20

The first term a = 10

The common difference d = second term - first term

The common difference d = 12 - 10 = 2

The series is an arithmetic sequence and the 20th term of the sequence will be

a₂₀ = a + ( n - 1 )d

a₂₀ = 10 + ( 19 ) 2

a₂₀ = 10 + 38

a₂₀ = 48 tiles

Hence , the series is an arithmetic sequence

PLEASE HELP!!! very confused

Answers

Answer:

Step-by-step explanation:

The vertices lie on the x-axis, as is determined by their coordinates. This makes the center of this hyperbola (0, 0) because the center is directly between the vertices. The fact that the foci also lie on the x-axis tells us that this is the main axis. What this also tells us is which way the hyperbola "opens". This one opens to the left and the right as opposed to up and down. The standard form for this hyperbola is:

[tex]\frac{(x-h)^2}{a^2}-\frac{(y-k)^2}{b^2}=1[/tex] and so far we have that h = 0 and k = 0.

By definition, a is the distance between the center and the vertices. So a = 5, and a-squared is 25. So we're getting there. Now here's the tricky part.

The expressions for the foci are (h-c, k) and (h+c, k). Since we know the foci lie at +/-13, we can use that to solve for c:

If h+c = 13 and h = 0, then

0 + c = 13 and c = 13.

We need that c value to help us find b:

[tex]c^2=a^2+b^2[/tex] and

[tex]13^2=5^2+b^2[/tex] and

[tex]169=25+b^2[/tex] and

[tex]144=b^2[/tex] so

b = 12. Now we're ready to fill in the equation:

[tex]\frac{x^2}{25}-\frac{y^2}{144}=1[/tex] and there you go!

Answer:

x = 7, EF = 10, FG = 12

Step-by-step explanation:

EF = 4x - 18

FG = 3x - 9

EG = 22

EG = 22

EF + FG = 22

4x - 18 + 3x - 9 = 22

4x + 3x - 18 - 9 = 22

7x = 22 + 18 + 9

7x = 49

x = 7

EF = 4x - 18

EF = 4*7 - 18

EF = 28 - 18

EF = 10

FG = 3x - 9

FG = 3*7 - 9

FG = 21 - 9

An investor has an account with stock from two different companies. Last year, his
stock in Company A was worth $6600 and his stock in Company B was worth $3500.
The stock in Company A has increased 7% since last year and the stock in Company B
has increased 1%. What was the total percentage increase in the investor's stock
account? Round your answer to the nearest tenth (if necessary).

Answers

22.7%

Given that last year stock for company A was $7200
The stock for company B last year was worth $3510
Stock in company A decreased by 24%
This means the new value of stock for company A became;
(100-24)/100 *$7200
76/100*$7200
0.76*7200 =$5472
Stock in company B decreased by 20%
This means the new value of stock for company B became;
(100-20)/100 *$3510
80/100*$3510
0.8*$3510
$2808
Original investors stock value was = $7200+$3510 =$10710
New investors stock value is = $5472+$2808=$8280
Decrease in value of stock = $10710-$8280 =$2430
percentage decrease in stock value = decrease in stock/original value of stock *100%
=2430/10710 *100 =22.689

1. The position of a particle moving along a coordinate axis is given by: s(t) = t^2 - 5t + 1. a) Find the speed of the particle b) Find the acceleration of the particle c) Find the velocity of the particle

Answers

Answer: [tex]\left | 2t-5\right |,\ 2,\ 2t-5[/tex]

Step-by-step explanation:

Given

Position of the particle moving along the coordinate axis is given by

[tex]s(t)=t^2-5t+1[/tex]

Speed of the particle is given by

[tex]\Rightarrow v=\dfrac{ds}{dt}\\\\\Rightarrow v=\dfrac{d(t^2-5t+1)}{dt}\\\\\Rightarrow v=\left | 2t-5\right |[/tex]

Acceleration of the particle is

[tex]\Rightarrow a=\dfrac{dv}{dt}\\\\\Rightarrow a=2[/tex]

velocity can be negative, but speed cannot

[tex]\Rightarrow v=\dfrac{ds}{dt}\\\\\Rightarrow v=\dfrac{d(t^2-5t+1)}{dt}\\\\\Rightarrow v=2t-5[/tex]

Recall that by definition:

[tex]\displaystyle \tan x=\frac{\sin x}{\cos x}[/tex]

Answer:

Step-by-step explanation:

$20.32 divided by 16 = $1.27

each cookie cost $1.27

I really hope this help

Answer:- 16x - 7 = 13.32

Also cost of each cookie = $1.27

Explanation:

Let the cost of each cookies be x

ATQ

16x -7 = 13.32

We will mutiply x with 16 because he purchased 16 cookies.

Also he had coupon of $7 which means $7 off which is why -7

And 13.32 is the amount he paid

Now lets solve it

16x - 7 = 13.32

16x = 13.32 + 7

16x = 20.32

x = 20.32/16

x = 1.27

Therefore cost of each cookie is $1.27
