Answer:

  • AED 3000

Step-by-step explanation:

Let the invested amount is x

  • Interest rate is r = 5% simple = 0.05 times
  • Time is t =  3 years
  • Interest amount I = AED. 450

<u>Using the interest formula and solving for x:</u>

  • P*r*t = I
  • x*0.05*3 = 450
  • 0.15x = 450
  • x = 450/0.15
  • x = 3000

The amount invested is AED 3000

A deck of 14 cards numbered 1 through 14 is dealt to Ken and Gunther so that each gets 7 cards. Each player's score is the sum o
aliya0001 [1]

Answer:

The different winning scores possible are 25 (from 28 to 52).

Step-by-step explanation:

  • The minimum score obtained by a player will be 28.

since, we divide 1-7 numbered to one and 8-14 to the other player such that    one receives the maximum and the other receives the minimum.

 the least minimum possibility is :28 as one get the card as(1,2,3,4,5,6,7).

while the other player gets 77 sum and loses.

  • for increasing this score now we give the number 1,2,3,4,5,6,8 to one of the player so that they sum upto 29 and will get the minimum score and wins while the other player gets 76 sum with the help of numbers{9,10,11,12,13,14,7} and loses.
  •    next possible minimum sum to win will be 30 by assigning 1,2,3,4,5,6,9 whereas the other gets the sum 75 and loses.
  • continuing in the same way we see that the minimum sum obtained to win will be 52( by assigning 2,3,6,7,9,12,13) while the other gets the sum 53 and loses.

    Hence, there are total 25 winning scores possible.  (from 28 to 52 i.e. 52-28=25).

PLEASE I NEED THIS ANSWER At the local ballpark, the team charges $8 for each ticket and expects to make $1,100 in concessions.
vladimir1956 [14]

Answer:

The answer is d 200

Step-by-step explanation:

with all the information given you come out with the equation

11x+ 1100=3300

Because 8 per ticket plus 3 for each bat equals 11 and then add the 1100 from the concession.

In the end you have to pay the players and the workers so that all equals to 3300

So now you have to solve for x

get x by itself by subtracting 1100 to 3300 which equals 2200

11x=2200

and then get x completely by its self divide 2200/11

and x= 200

hope this helped!

Help me with this question
Colt1911 [192]

Step-by-step explanation:

just look at the graphic : what value do we have on the cost side, when we have 1 pounds on the amount side ?

all the answer options specify a price per pound. that is why we only need to focus on the price for one pound.

we see in the graphic, that for 1 pound the price is $4.

just to make sure, we can also work with the directly specified point (0.5, 2), which means that 0.5 pounds cost $2.

and the function is clearly a straight line.

so, every point on the function has the same y/x ratio (slope).

therefore,

2/0.5 = 4

now, what point with x=1 has the same ratio ?

y/1 = 4

y = $4

perfect, the results are identical. so, $4 per pound is the correct answer.
