What is the area of a square if one side is 25 feet long?

Mathematics

Maslowich3 years ago

Answer:

625 ft²

Step-by-step explanation:

In a square, all of the sides are the exact same length.

We know that one side is 25 feet long, so using the previous knowledge, we know that all of the other sides are also 25 feet long.

To find the area of a square, you multiply two sides together, in this case 25*25

25² or 25*25 equals 625. Don't forget your answer will be feet² because we are finding the area!

What is the interest earned on $3000 at a rate of 0.04 for three years? The formula is interest equals (principal) (rate) (time)
bekas [8.4K]

<u>Answer:</u>

The interest after 3 years is $360

<u>Explanation:</u>

Given the principal amount (P) = $3000

Rate of interest (R) = 0.04

Time period (T) is given as 3 years

The Simple Interest is calculated by the formula;

SI = Principal \times Rate of Interest \times Time

Substituting the values in the above formula,

SI = 3000 \times 0.04 \times 3

SI = $360

Therefore, the interest after 3 years is $360

A cube measures 3.0 CM on each side and has a mass of 25g. What is the density?
Oxana [17]

Answer:

D ≈ 0.925926 g/cm³

Step-by-step explanation:

Density = Mass / Volume

Step 1: Define

M = 25 g

V = (3 cm)³ = 27 cm³

D = ?

Step 2: Substitute and Evaluate for Density

D = 25g / 27 cm³

D = 25/27 g/cm³

D ≈ 0.925926 g/cm³

The time taken for 21000 spectators to vacate the stadium , if only 15 exits are functional is 28 minutes .

In the question ,

it is given that

the time taken to vacate the stadium = 20 minutes

number of exits = 25 exits

capacity of the stadium = 25000 spectators .

given that ,

time taken to exit the stadium varies directly with number of spectators and inversely with the number of exits .

time taken ∝ number of spectators ∝ 1/number of exits .

to remove the proportionality sign , we write the constant

time taken = k * (number of spectators)/(number of exits) .

20 = k * 25000/25

20 = k * 1000

k = 20/1000

k = 2/100

k = 1/50 = 0.02

So, to find the time taken for 21,000 spectators to vacate the stadium, if only 15 exits are functional , we use the formula

time taken = (0.02)*(21000/15)

= 0.02*1400

= 28

Therefore , The time taken for 21000 spectators to vacate the stadium , if only 15 exits are functional is 28  minutes .

7x^2=63<br><br> solve for x<br> please show work
o-na [289]

Answer:

x = ±3

Step-by-step explanation:

Step 1: Write equation

7x² = 63

Step 2: Solve for <em>x</em>

  1. Divide both sides by 7: x² = 9
  2. Square root both sides: x = ±3

Step 3: Check

<em>Plug in x to verify it's a solution.</em>

7(3)² = 63

7(9) = 63

63 = 63

7(-3)² = 63

7(9) = 63

63 = 63
