kotykmax [81]

If Ted has $55. 00 in his pocket then out of  two books for $29. 95 each headphones for $29. 99 and a portable speaker set for $30. 95 an MP3 player for $35. 99 and a $20. 00 gift card for downloading music three books for $16. 99 each he can purchase  three books for $16. 99 each.

<h3>How to calculate total money spent ?</h3>

To calculate total money spent we have to add all the money we spent on all things.

Given that Ted has $55. 00 in his pocket.

(i)

two books for $29. 95 each

Money needed for 2 books = 2\times 29.95=59.9

So Ted is not able to purchase 2 books

(ii) headphones for $29. 99 and a portable speaker set for $30. 95

Money needed for headphones and portable speaker = 29.99+30.95=60.94

So Ted is not able to purchase  headphones and portable speaker

(iii)  an MP3 player for $35. 99 and a $20. 00 gift card for downloading music

Money needed for MP3 player and gift card= 35.99+20.00=55.99

So Ted is not able to purchase  MP3 player and gift card

(iv) three books for $16. 99 each.

Money needed for 3 books =3\times16.99=50.97

So ted is able to purchase these three books .

If Ted has $55. 00 in his pocket then out of  two books for $29. 95 each headphones for $29. 99 and a portable speaker set for $30. 95 an MP3 player for $35. 99 and a $20. 00 gift card for downloading music three books for $16. 99 each he can purchase  three books for $16. 99 each.

Suppose the cost of college tuition is expected to increase 5% every year. How much will the tuition at a comunity college cost
evablogger [386]

Answer:

$7,596.43

Step-by-step explanation:

The cost of the college tuition is increasing 5% compounded annually for 5 years.

∴ A = P(1 + r%)ⁿ

where A = tuition fee after 5 years.

           P = current tuition

           r = rate of increase

            n = period

A =  $5,952(1 + 5%)⁵

     = $5,952(1 + 0.05)⁵

     =  $5,952 × 1.05⁵

     = $7,596.43

    =

Can someone help me with these? No clue how to do it or what the answer is​
astraxan [27]

Answer:

see explanation

Step-by-step explanation:

Given

f(x) = x^{4} + 3x³ - 4x²

To find the zeros equate f(x) to zero, that is

x^{4} + 3x³ - 4x² = 0 ← factor out x² from each term

x²(x² + 3x - 4) = 0 ← factor the quadratic

x²(x + 4)(x - 1) = 0 ← in standard form

Equate each factor to zero and solve for x

x² = 0 ⇒ x = 0 with multiplicity 2

x + 4 = 0 ⇒ x = - 4

x - 1 = 0 ⇒ x = 1

zeros are x = - 4, x = 0, x = 1

6(2x + 4) = 3(4x + 8)<br> Please answer this!
Ahat [919]

Answer:

Infinitely many solutions

Step-by-step explanation:

6(2x + 4) = 3(4x + 8)

Distribute the 6

6 * 2x = 12x and 6 * 4 = 24

12x + 24 = 3(4x+8)

Distribute the 3

3 * 4x = 12x and 3 * 4 = 24

12x + 24 = 12x + 24

On both sides of the equal sign we have 12x + 24.

When both sides are equal there are infinitely many solutions.

Help me please !
scoray [572]
Marcus score is 13.7, the mean is 12.89, and the standard deviation is 1.95, so I’ll do ( 13.7 – 12.89)/ 1.95, Since Marcus' z-score is 0.415. The area to the left of the z-score is 65.9% so therefore Marcus did scored better than 65.9% of the students. So Marcus needs to score 98% better of all the other students in order for him to receive an actual certificate.
