Ann buys a dress in a sale. The normal price of the dress is £36 and it is reduced by 20%. Work out the sale price of the dress.

Answers

Reduced by 20% means it is on sale for 80% of the original price ( 100% - 20% = 80%)

Multiply the original price by 80%

36 x 0.8 = 28.80

The sale price is £28.80

Suppose on April 1, a gag store sold a total of 27 widgets and wombats combined. If widgets cost
$0.75, wombats cost $1.25, and the store received a total of $27.75 for these two items, how
many of each item did the store sell?

Answers

Answer:

Widgets: 12

Wombats: 15

Step-by-step explanation:

Let x represent widgets

y represent wombats

Set up the equations

(1) x + y = 27

(2) 0.75x + 1.25y = 27.75

Solve equation (1), x + y = 27 for x

x = 27 - y

Substitute 27- y for x into equation (2)

0.75(27 - y) + 1.25y = 27.75

0.5y + 20.25 = 27.75

0.5y = 7.5

y = 15

Substitute 15 for y into equation (2)

x = 27 - 15

find the side length of a cube with a volume of 69 to the 3 power yds . If necessary, round your answer to the nearest tenth.

Answers

Answer:

the side length of the cube is 4.10

Step-by-step explanation:

The computation of the side length of the cube is shown below:

As we know that

The volume of the cube is side^3

So,

69^3 = s^3

Now the side length of the cube is

= ∛69

= 4.10

Hence, the side length of the cube is 4.10

Given

[tex]\frac{3}{x+4}[/tex] - [tex]\frac{1}{x+3}[/tex] = [tex]\frac{x+9}{x^2+7x+12}[/tex] ← factor the quadratic

[tex]\frac{3}{x+4}[/tex] - [tex]\frac{1}{x+3}[/tex] = [tex]\frac{x+9}{(x+3)(x+4)}[/tex]

Multiply through by (x + 3)(x + 4) to clear the fractions

3(x+3) - (x + 4) = x + 9 ← distribute and simplify left side

3x + 9 - x - 4 = x + 9

2x + 5 = x + 9 ( subtract x from both sides )

x + 5 = 9 ( subtract 5 from both sides )

x = 4

Amy spins a spinner with equal sections numbered 1 through 5 and flips a fair coin. Which statement represents the probability of spinning a 4 and landing on
heads?

Answers

Answer:

There is a 1 out of 10 chance of spinning a 4 and landing on heads, so the probability is 110.

The probability of spinning a 4 and landing on heads is 1/10.

What is Probability?

Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.

The value of probability will be always in the range from 0 to 1.

We have two experiments here.

Spinning a spinner with sections 1 to 5 and flipping a coin.

Spinning the spinner will have five outcomes.

Flipping a coin will have two chances, either head or tail.

Total number of outcomes = 5C₂ = 10

There is only a chance of getting a 4 on the spinner and landing on heads.

Probability = 1/10.

Hence the required probability is 1/10.

Derek bought his truck for $30,000. The value has dropped by $900 each year. He determined that the value of his truck (V) can be modeled by: V = 30,000 - 900x where x is the number of years since he bought his truck.

In how many years will his truck be worth $4,800?

Answers

Answer:

28 years

Step-by-step explanation:

The difference between 30,000 and 4,800 is 25200. So we divide this number by 900 to find out how many years it will take for the truck to depreciate to this value

a football field is drawn to a scale of 1cm represents 5cm if the field is 70m by 50m find the length and breadth on the drawing​

Answers

Answer:

length of the drawing will be 14cm and breadth will be 10cm.

Step-by-step explanation:

if actual 5m represents 1cm in drawing then,

5m = 1cm

1m = 1/5cm

70m = (1/5)×70cm =14cm

likewise,

50m = (1/5)×50cm =10cm

thus, length in drawing is 14cm and breadth in drawing is 10cm.

Alpha Corporation has just paid its annual dividend and is looking forward to another successful year ahead. The company had free cash flow for the year just ended of $1 billion, all of which it just paid out to its shareholders as a dividend. Right now, shareholders do not believe that Alpha has any growth opportunities, so they expect the annual cash flow and dividend stream to remain unchanged for the foreseeable future. Alpha has 100 million 3 shares outstanding and a market capitalization of $10 billion. The company is entirely equity-financed. The capital market is efficient.A) Alpha's CEO now proposes that the company skip its dividend one year from now and instead invest the entire amount of the coming year's $1 billion free cash flow in a project that management believes will generate a perpetual annual rate of return of 21%. The CEO further asserts that the new project has similar risk to the company's assets in place. If the company were to announce immediately its plans for the investment one year from now (financed by skipping next year's dividend) what do you think will happen to Alpha's stock price? B) Some of Alpha's Board members are worried that shareholders are expecting a dividend next year and that announcing plans to skip next year's dividend will lower the stock price today. Suppose Alpha were to announce instead that it plans to pay its usual dividend one year from now and that it has no plans for any new investment at T-. What will happen to the stock price today? C) Suppose Alpha settles on a compromise: Alpha announces today that it will invest in the new project one year from now, butwill simultaneously issue enough new shares at that time to enable it to pay the usual S10 dividend per share to its existing shareholders. What do you think will happen to Alpha's share price one year from now under this plan? What do you think will happen to Alpha's stock price today?
