Answer:

the length is 33 feet

Step-by-step explanation:

The computation of the length is shown below:

Let us assume the length be x

So the width be 1 by 3 x

And the area is 363 square feet

So

As we know that

Area = length × width

363 = x × 1 ÷ 3 x

363 = 1 ÷ 3x^2

Now

363 × 3 = x^2

1089 = x^2

x = 33 feet

hence, the length is 33 feet

Answer:

(x + 1)² + (y + 1)² = (√6)²

Step-by-step explanation:

Group the x- and y- terms together:

9x^2 + 18x + 9y^2 + 9y = 36

Factor out the coefficient 9:

x^2 + 2x + y^2 + y = 4

Complete the square of x^2 + 2x and then do the same for y^2 + 2y:

x^2 + 2x + 1 - 1 + y^2 + 2y + 1 - 1 = 4

Rewrite x^2 + 2x + 1 as the square of the binomial x + 1:

(x + 1)^2 + (y + 1)^2 - 2 = 4

Collect the constant terms on the right side:

(x + 1)^2 + (y + 1)^2 = 6

Rewrite 6 as (√6)^2:

(x + 1)² + (y + 1)² = (√6)² is the equation in standard form (x - h)² + (y - k)² = r²

Completing the square is done as follows:  x^2 + 2x

Start with x^2 + 2x

1.  Take half of the coefficient of x, which results in 2/2, or 1

2.  Square this result and add it to, and subtract it from x^2 + 2x

     x^2 + 2x + 1 - 1

3.  Rewrite the first three terms as the square of a binomial:  

     x^2 + 2x + 1 - 1 = (x + 1)² - 1.

Do the same for y² + 2y.

Answer:

-79.78 (really stinking cold)

Step-by-step explanation:

Solving the equation will go like this:

5/9(F - 32) = -62.1

multiply both sides by 9 to get rid of the fraction

5 (F - 32) = -558.9

divide both sides by 5

F - 32 = -111.78

add 32 to both sides

F = -79.78

Answer:

The "power rule" tells us that to raise a power to a power, just multiply the exponents. Here you see that 52 raised to the 3rd power is equal to 56. The quotient rule tells us that we can divide two powers with the same base by subtracting the exponents.

Answer:

239,000

Step-by-step explanation:

Look at the digit to the right of the place you're rounding to. In this case, we are rounding to the thousands, so we look at the digit in the hundreds place. It's 8, which is above 5 (5 and above you round up. 4 and below, you round down). Because the 8 is above 5, we go back to the thousands place and bump the number (8) up one (to 9).

No this will not form a triangle.option B is correct.

Answer:

No, 64 doesn't fit

Step-by-step explanation:

64 is an outlier

since it lies too far from the other numbers

Answer:

(the volume of the hemisphere has no units, so i will suppose that it is 6m^3)

For a sphere of radius R, the volume is:

V = (4/3)*pi*R^3

Where pi = 3.14

And a hemisphere is half of a sphere, then the volume of a hemisphere of radius R is:

V = (1/2)*(4/3)*pi*R^3

We know that the volume of the hemisphere is 6 m^3, then we have the equation:

6 m^3 = (1/2)*(4/3)*3.14*R^3

Now we can solve this for R.

6 m^3 = 2.1*R^3

∛(6 m^3/2.1) = R = 1.41 m

The radius of the hemisphere is 1.41m

Now we want to find the surface of a sphere with this radius (if the radius is the same, then the diameter is the same)

For a sphere of radius R, the surface is:

S = 4*pi*R^2

Then the surface of this sphere is:

S = 4*3.14*(1.41 m)^2 = 24.971 m^2

I'm using a method my elementary teacher. My dearest apologizes if this is wrong.

Answer:

See explanation

Step-by-step explanation:

Let the number of adults = a and the number of children = c.

Since the number of people using the pool is 288, we know that a + c = 288

Based on the price information, we know that 1.75c + 2.5a = 528

Combining these two equations allows us to solve for the values of a and c, the process for which follows

a = 288 - c

1.75c + 2.5(288 - c) = 528

c = 256

a = 288 - c = 288 - 256 = 32

a = 32

c = 256

Notice that the result is a polynomial expression divided by a second polynomial expression. In this section, we will explore quotients of polynomial expressions.

Simplifying Rational Expressions

The quotient of two polynomial expressions is called a rational expression. We can apply the properties of fractions to rational expressions, such as simplifying the expressions by canceling common factors from the numerator and the denominator. To do this, we first need to factor both the numerator and denominator. Let’s start with the rational expression shown.

Answer:

Step-by-step explanation:

Use the identity :   a² - b² = (a + b )(a - b)

25 and 36 should be written in the form raised to power 2

25 = 5 * 5  = 5²

36  = 6 * 6 = 6²

[tex]\frac{e^{2}}{25}-\frac{f^{2}}{36}=\frac{e^{2}}{5^{2}}-\frac{f^{2}}{6^{2}}\\\\=(\frac{e}{5})^{2}-(\frac{f}{6})^{2}\\\\=(\frac{e}{5}+\frac{f}{6})(\frac{e}{5}-\frac{f}{6})[/tex]

Answer: 35%

Explanation: Divide 7/20

Answer:

58%

Step-by-step explanation:

Given the exponential relation :

Y=52(0.42)^x

Since 0.42 is less than 1, then we can infer that the expression is a Decay function ;

. General form of a exponential function :

y = A(1 - r)^x ; r = Decay rate

Comparing the general equation with the equation given ;

The percentage rate of decrease is obtained thus :

1 - r = 0.42

1 - 0.42 = r

r = 0.58

Rate = 0.58 * 100%

Rate = 58%
