Answer:

29 feet in length, 5 feet in width and 12 feet in height

Step-by-step explanation:

We have that for the volume of a quadrangular prism is:

V = l * w * h

Ie length times width times height

In this case, the height is determined by the squares that you put in each corner, taking into account that a square has all the same sides, the height is 12 inches. h = 12

they tell us that the length is 24 inches more than the width, that is, l = 24 + w

replacing we have:

1740 = (24 + w) * w * 12

1740 = 12 * w ^ 2 + 288 * w

12 * w ^ 2 + 288 * w - 1740 = 0

if we calculate the root, we have w = 5 or w = -29

only works when w = 5

Thus:

l = 24 + 5

l = 29

which means that the dimensions are:

29 feet in length, 5 feet in width and 12 feet in height

Write a recursive formula for each sequence given or described below.

valentinak56 [21]

Answer:

$a_{n} =a_{n-1} +3000$ and a₁ =30000 for n = 2,3,4,5,6, ......

Step-by-step explanation:

Doug has joined a job with a starting salary of $30000 per year.

Hence, if a₁ is the salary of Doug in the first year, then

a₁ =30000

Now, each year Doug will receive a raise of $3000 in his salary.

Hence, in the 2nd year, his salary(a₂) will become ( a₁ +3000) per year.

Again, in the 3rd year, his salary(a₃) will become ( a₂ +3000) per year.

Therefor, in the similar manner the recursive formula for his salary in each year will be given as $a_{n} =a_{n-1} +3000$ and a₁ =30000 for n = 2,3,4,5,6, ...... {aₙ is the yearly salary of Doug in the nth year} (Answer)

You like the size of your MP3 player. The width is 4 centimeters. The length is 7 centimeters. The height measures 1 centimeter.

Basile [38]

Answer:

78mm^2

Step-by-step explanation:

based on the information given, we can tell that the shape of the MP3 player is a rectangle. The formula for the surface area of a rectangle is SA=2WL+2LH+2HW

SA = Surface Area

W = Width

L = Length

H = Height

SA = 2(4)(7) + 2(7)(1) + 2(1)(4)

= 2(28) + 2(7) + 2(4)

= 56 + 14 + 8

= 78

State two numbers such that the grader number is 75% more than the lesser number

Marianna [84]

75% is equal to 3/4. So the easiest way to do this is to make the smaller number a multiple of 4. Let's say the smaller number is 8. To find the larger number, you must take 75% of 8 and then add it to 8. 1/4 of 8 equals 8 divided by 4, which is 2. Therefore, 3/4 of 8 is 6. 8 + 6 = 14.

Thus, your two numbers could be 8 and 14.
