The length and width of the rectangular pool are respectively; Length = 22 meters and Width = 17 meters

Area of the pool which is a rectangle has the formula;

A = Length(L) * Width(w)

Let the width of the pool = x

Then the length will = (x + 5)

Since the walkway is 3 meters wide, It means that the overall dimensions will be (x + 6) by (x + 5 + 6) or (x + 11)

Total area - pool area = 270

Thus;

(x + 11) * (x + 6) - x(x + 5) = 270

x² + 11x + 6x + 66 - x² - 5x = 270

17x - 5x + 66 = 270

12x + 66 = 270

12x = 270 - 66

x = 204/12

x = 17

Length of pool = x + 5 = 17 + 5 = 22 meters

Answer:

We can use the formula for compound interest to solve this problem. The formula is:

A = P * (1 + r/n)^(n*t)

where:

A = the amount of money after t years

P = the principal amount (the initial investment)

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the number of years

In this case, P = $5000, r = 0.03, n = 12 (since the interest is compounded monthly), and t = 10. Plugging these values into the formula, we get:

A = 5000 * (1 + 0.03/12)^(12*10)

A = 5000 * (1.0025)^120

A ≈ $6,621.36

So the investment will be worth approximately $6,621.36 after 10 years.

Answer:

The radius of the circle is 24.5 units

Step-by-step explanation:

The formula for the circumference of a circle is \(C=2\pi r\)

Where \(C\) is the circumference and \(r\) is the radius.

Lets solve for \(r\).

Divide both sides of the equation by \(2\pi\).

\(\dfrac{C}{2\pi}=r\)

Now we have an equation to evaluate the radius.

Numerical Evaluation

In this example we are given

\(C=153.86153\\\pi =3.14\)

Substituting our values into our equation for the radius yields

\(r=\dfrac{153.86153}{2*3.14}\)

\(r=\dfrac{153.86153}{6.28}\)

\(r=\dfrac{153.86153}{6.28}\)

\(r=24.5\)

The total surface area of the prism is equal to 74 m².

In Mathematics, the total surface area of a triangular prism can be calculated by using this mathematical expression:

Total surface area of triangular prism = (Perimeter of the base × Length of the prism) + (2 × Base area)

Total surface area of triangular prism = (S₁ + S₂ + S₃)L + bh

where:

By substituting the given parameters, we have:

Total surface area of triangular prism = 4 + (5 × 4)3.5

Total surface area of triangular prism = 4 + (20)3.5

Total surface area of triangular prism = 74 m².

Answer:

26.36, 52.72, 65.90

Step-by-step explanation:

write the formula

2x + 4x + 5x = 145

add all the xs together

11x = 145

find x

11x ÷ 11 = 145 ÷ 11

x = 13.1818

subsitute the value of x to 2x, 4x, and 5x to find the side lengths

2(13.1818) = 2.3636

4(13.1818) = 52.7272

To one decimal place,

y = 16.3 m

Step-by-step explanation:

Using SOHCAHTOA,

In this case we need to use CAH,

WE know the angle = 25 and the hypotenuse H = 18,

so,

y = adjacent

\(cos(angle) = y/H\\y = (18)(cos(25))\\y = 16.3135\\y = 16.3\)

Answer: 16.3 in.

Step-by-step explanation:

use SOH CAH TOA

cos x = adj/hyp

cos 25  = y/18

18 cos 25  = y

y= 16.3

The percentage change in GDP is 2.04%

Percentage Change is the difference coming after subtracting the old value from the new value and then divide by the old value and the final answer will be multiplied by 100 to show it as a percentage. Generally, to convert a fraction into a percent, we multiply it by 100.

The formula of percentage change is given as

Percentage change =[ (New increase - old value) / old value] * 100

Percentage change = [(14.72 - 14.42) / 14.72] * 100

Percentage change = 2.04%

In this case, there is a percentage decrease of 2.04%

The effect of subtracting 2 from the input on the graph of the function is a translation of 2 units to the right.

For any function f(x), we define a horizontal translation of N units as:

g(x) = f(x + N)

And what this does, is translate the graph N units horizontally.

if N > 0, then the translation is to the left.

if N < 0, then the translation is to the right.

Here we want to subtract 2 from the input, so we will get:

f(x - 2)

7d^2

Answer: choice A) \(7d^2\)

This is the same as writing 7d^2

==================================================

Explanation:

When we add a number to itself repeatedly, we can use multiplication to shorten things. For example: 3+3+3+3 = 5*3 = 15. We have five copies of '3' being added, which explains the 5 times 3.

Extending this idea leads us to shortening repeated multiplications into exponentiations. In the case of \(7*d*d\), we have two copies of 'd' being multiplied. We replace \(d*d\) with \(d^2\) which is the same as d^2. The ^ symbol means "exponent".

The exponent (2) tells us how many copies of the base (the term d) we multiply out.

Another example would be \(d^3 = d*d*d\)

So that's why \(7*d*d = 7d^2\)

Step-by-step explanation:

Trigonometric Ratios

The ratios of the sides of a right triangle are called trigonometric ratios.  The longest side of the triangle is called the hypotenuse and the other two sides are called the legs.

We are given a triangle with side lengths of 3, \(\sqrt{72}\), and 9, where 9 is the hypotenuse. Before applying the trigonometric ratios, we must check if the triangle is right, and the Pythagora's theorem is satisfied:

\(9^2=3^2+(\sqrt{72})^2\)

81=9+72=81

Now we're sure it's a right triangle, we apply the sine formula:

\(\displaystyle \sin A=\frac{\text{opposite leg}}{\text{hypotenuse}}\)

The opposite leg to A is 3, and the hypotenuse is 9, then:

\(\displaystyle \sin A=\frac{3}{9}\)

Simplifying:

\(\boxed{\displaystyle \sin A=\frac{1}{3}}\)
