Answer:

The volume of a cube whose total surface area is 150 sq. ft. is 125 cubic feet.

Step-by-step explanation:

Set up an equation that shows the relation between the side length L of the cube and its surface S:

[tex]S = 6\cdot L^2\\150 = 6\cdot L^2\implies\\|L| = \sqrt{\frac{150}{6}}= 5[/tex]

The side length of a cube with an area of 150 sq. ft is 5 ft. Now we can easily calculate the volume V:

[tex]V = L^3 = 5^3 = 125[/tex]

The volume of a cube whose total surface area is 150 sq. ft. is 125 cubic feet.

The volume of a cube with a total surface area of 150 square feet is 125 cubic feet. This is found by first dividing the total surface area by 6 to find the area of one face, then taking the square root to find the length of one side, and finally cubing this length.

To find the volume of a cube when you know the total surface area, you begin by realizing that a cube has six identical faces. Hence, the surface area of one face is the total surface area divided by 6. In this case, 150 square feet divided by 6 equals 25 square feet. This is the area of one face. Because this is a cube, the length, width, and height are equal, so the square root of 25 (which is 5) would give us the length of one side.

Now, the volume of a cube is the side length cubed. Hence, in this case, the volume would be 5 feet (the length of a side) cubed, or 5 * 5 * 5, which equals 125 cubic feet.

Answer:

16 1/2, or 16.5 square meters

Step-by-step explanation:

This is a simple explanation, scroll down for the details on how I got to this answer!

Step 1. Find the rate at which Rachel can paint.

(5 1/2 square meters per 1/3 hour)

Step 2. Find the area of wall space Rachel can paint in 1 hour, using this rate.

5 1/2 × 3 = 16 1/2 or 16.5 square meters

1/3 × 3 = 1 hour

Rachel can paint 16 1/2 square meters of wall space in 1 hour.

**How I solved this problem**

Step 1. To find the area of wall space Rachel can paint in 1 hour, we need to find a rate that shows her speed (square meters/hours).

In the first sentence, we are given a rate:

"5 1/2 square meters of wall space in 1/3 hour."

This can be modeled by the fraction: [tex]\frac{5\frac{1}{2} }{\frac{1}{3} }[/tex]

Step 2. To find how much she can paint in 1 hour, we can multiply this rate by 3. This is because the rate tells us that the area of wall space Rachel can paint in 1/3 hour.

Remember, to cancel out a fraction, multiply by its reciprocal, which is the fraction "flipped" (the numerator and denominator switch). We multiply 1/3 by 3/1 (3) because it is 1/3 flipped.

Since Rachel is painting at a constant rate of 5 1/2 square meters per 1/3 hour, we also need to multiply the other part of the fraction by 3, so the rate stays the same.

5 1/2 × 3 = 16 1/2 or 16.5 square meters

1/3 × 3 = 1 hour

This is our final answer: Rachel can paint 16 1/2 square meters of wall space in 1 hour.

Rachel can paint 16 1/2 square meters of wall space in one hour by multiplying her painting rate for 1/3 hour by 3.

Rachel paints 5 1/2 square meters of wall space in 1/3 hour. To determine the area she can paint in one hour, we need to use the concept of unit rate, which is the amount of work done per unit of time.

To find Rachel's painting rate in square meters per hour, we can set up a proportion. Since we want to find out how much she can paint in one full hour, we multiply the area she can paint in 1/3 of an hour by the reciprocal of 1/3 (which is 3) to calculate the full hour painting area.

So, Rachel's painting rate per hour is 5 1/2 * 3 square meters. Multiplying, we get (5 + 1/2) * 3 = (11/2) * 3 = 33/2 = 16 1/2 square meters. This is the area she can paint in one hour.

Answer:

The solution to the equation is:

Option c. b=0 and b=4

Step-by-step explanation:

5 / (3b^3-2b^2-5) = 2 / (b^3-2)

Cross multiplication:

5(b^3-2)=2(3b^3-2b^2-5)

Applying distributive property both sides of the equation to eliminate the parentheses:

5(b^3)-5(2)=2(3b^3)-2(2b^2)-2(5)

Multiplying:

5b^3-10=6b^3-4b^2-10

Passing all the terms to the right side of the equation: Subtracting 5b^3 and adding 6 both sides of the equation:

5b^3-10-5b^3+10=6b^3-4b^2-10-5b^3+10

Adding like terms:

0=b^3-4b^2

b^3-4b^2=0

Getting common factor b^2 on the left side of the equation:

b^2 (b^3/b^2-4b^2/b^2)=0

b^2 (b-4) = 0

Two solutions:

(1) b^2=0

Solving for b: Square root both sides of the equation:

sqrt(b^2)=sqrt(0)

Square root:

b=0

(2) b-4=0

Solving for b: Adding 4 both sides of the equation:

b-4+4=0+4

Adding like terms:

b=4

The solution of the equation is: b=0 and b=4 (Option c)

Final answer:

To solve the equation, we can use the quadratic formula and find the solutions for b.

Explanation:

To solve the equation 5/3b^3 - 2b^2 - 5 = 2/b^3 - 2, we need to find the values of b that satisfy the equation. To do this, we can cross-multiply and rearrange the equation to get a quadratic equation in terms of b. Using the quadratic formula, which states that b = (-b ± √(b^2 - 4ac)) / 2a, we can find the solutions for b.

Substituting the values a = 5/3, b = -2, and c = -7 into the quadratic formula, we obtain the solutions b = -4 and b = 0.

Therefore, the solution to the equation 5/3b^3 - 2b^2 - 5 = 2/b^3 - 2 is b = -4 and b = 0.

Answer:

a1 = 2; an = a(n-1) + 3/2

Step-by-step explanation:

Common difference = 7/2 - 2

= 7/2 - 4/2

= 3/2  

(Also 5 - 7/2 = 3/2.)

First term a1 = 2

So the formula is  a1 = 2; an = a(n-1) + 3/2 which is the first choice.

The recursive formula for the arithmatic sequence is a₁ = 2, aⁿ = aⁿ⁻¹ + 3/2.

A recursive formula is a formula that defines any tern of a sequence in terms ofits preceding term(s).

Now the given series is-

2,7/2,5,13/2,......

Here the the first term of the series is 2

⇒a₁ = 2

Common difference (d) = (7/2) - 2 = 3/2

Now the recursive formula of an arithmatic sequence is given as,

aⁿ = aⁿ⁻¹ + d

Putting the values,

aⁿ = aⁿ⁻¹ + 3/2

Hence,the recursive formula for the arithmatic sequence is a₁ = 2, aⁿ = aⁿ⁻¹ + 3/2.

Answer:

1.75 %  

Step-by-step explanation:

The formula for the future value (FV) of an investment is

FV =PV(1 + r/n)^nt

If the interest is calculated once a year, n = 1, and the formula reduces to

     FV = PV(1 +r)^t

5550 = 5000(1 + r)⁶     Divide both sides by 5000

 1.110 = (1+r)^6              Take the sixth root of each side

 1 + r = 1.0175               Subtract 1 from each side

      r = 0.0175               Convert to percent

     r = 1.75 %

The interest rate is 1.75 %.

Answer:

(x + 3)² + (y+ 2)² = 1²

Step-by-step explanation:

The standard form for the equation of a circle with centre (a, b) and radius r is

(x - a)² + (y - b)² = r²

x² + 6x + y² + 4y + 12 =  0

Step 1. Subtract the constant from each side

x² + 6x +           y² + 4y        = -12

Step 2. Complete the squares for x and y

Square half the coefficients of x and y

(x² + 6x + 3²) + (y² + 4y + 2²) = -12 + 3² + 2²

Step 3. Write the lhs as squares of binomials

(x + 3)² + (y+ 2)² = -12 + 3² + 2²

Step 4. Convert the rhs to a square

(x + 3)² + (y+ 2)² = -12 + 9 + 4

(x + 3)² + (y+ 2)² = 1

(x + 3)² + (y+ 2)² = 1²

The graph below shows that this is the equation for a circle with

centre (-3, -2) and radius 1.

The center and radius of the given circle are respectively; (-3, -2) and 1

The standard form for the equation of a circle with it's centre coordinate (a, b) and radius r is given as;

(x - a)² + (y - b)² = r²

Now, we are given the circle equation to be; x² + 6x + y² + 4y + 12 =  0

Let us subtract 12 from both sides to leave only the variables on the left side;

x² + 6x + y² + 4y + 12 - 12 =  0 - 12

x² + 6x + y² + 4y = -12

Now let us complete the squares for variable x and y;

Square half the coefficients of x and y and add to both the x, y and constant to get;

(x² + 6x + 3²) + (y² + 4y + 2²) = -12 + 3² + 2²

(x² + 6x + 3²) + (y² + 4y + 2²) = -12 + 9 + 4

(x² + 6x + 3²) + (y² + 4y + 2²) = 1

Write the left hand side as squares of binomial to get;

(x + 3)² + (y+ 2)² = 1

This can be also written as;

(x + 3)² + (y+ 2)² = 1²

Thus, from the general standard form of equation of a circle, we can say that;

centre is at (-3, -2) and radius is 1.

Step-by-step explanation:

the sum to n terms of an arithmetic sequence is

[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex][2a + (n - 1)d ]

where d is the common difference and a is the first term

here d = 9 - 7 = 7 - 5 = 2 and a = 5, hence

[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex][(2 × 5) + 2(n - 1) ]

                        = [tex]\frac{n}{2}[/tex](10 + 2n - 2)

                        = [tex]\frac{n}{2}[/tex](2n + 8)

                        = n² + 4n

When sum = 165, then

n² + 4n = 165 ← rearrange into standard form

n² + 4n - 165 = 0 ← in standard form

(n + 15)(n - 11) = 0 ← in factored form

equate each factor to zero and solve for n

n + 15 = 0 ⇒ n = - 15

n - 11 = 0 ⇒ n = 11

but n > 0 ⇒ n = 11

The sum of n terms for the arithmetic series is:

[tex]S_n=\frac{n}{2}[8+2n ][/tex]

The value of n for which the series has sum 165 is 11

The given series is:

5 + 7 + 9 +.......

The first value, a = 5

The common difference, d = 7 - 5

d  =  2

The sum of the first n terms of an arithmetic series is given by the formula:

[tex]S_n=\frac{n}{2}[2a+(n-1)d ][/tex]

Substituting a = 5, and d = 2 into the sum of the series, we have:

[tex]S_n=\frac{n}{2}[2(5)+(n-1)(2) ]\\\\S_n=\frac{n}{2}[10+2n-2 ]\\\\S_n=\frac{n}{2}[8+2n ][/tex]

To determine the value of n for which the series has sum 165, substitute [tex]S_n=165[/tex] into the sum above

[tex]S_n=\frac{n}{2}[8+2n ]\\\\165=\frac{n}{2}[8+2n ]\\\\2(165)=n(8+2n)\\\\2n^2+8n-330=0\\\\n^2+4n-165=0\\\\n^2-11n+15n-165=0\\\\n(n-11)+15(n-11)=0\\\\(n-11)(n+15)=0\\\\n=11, n=-15[/tex]

(- 25, 81) does not lie on the line

Step-by-step explanation:

We can use the slope m to determine if (- 25, 81) lies on the line or not

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (2, 0)

m = [tex]\frac{0-4}{2-0}[/tex] = [tex]\frac{-4}{2}[/tex] = - 2

now if (- 25, 81) lies on the line then the slope between (- 25, 81) and either of the 2 points on the line should equal - 2

(x₁, y₁ ) = (- 25, 81) and (x₂, y₂ ) = (2, 0)

m = [tex]\frac{0-81}{2+25}[/tex] = [tex]\frac{-81}{27}[/tex] = - 3

The slopes are not equal hence (-25, 81) does not lie on the line

[tex]\text{Step 1:}\\\\\text{Find the equation of the line passing through the points}\\\\\text{The slope-intercept form:}\ y=mx+b\\\\m-slope\\b-y-intercept\to(0,\ b).\\\\\text{We have the points:}\\(0,\ 4)-y-intercept\to b=4\\(2,\ 0)-x-intercept\\\\\text{Therefore we have the equation:}\ y=mx+4.\\\\\text{The formula of a slope}\\\\m=\dfrac{y_2-y_1}{x_2-x_1}\\\\\text{put the coordinates of the points:}\\\\m=\dfrac{0-4}{2-0}=\dfrac{-4}{2}=-2\\\\\text{Therefore we have}\ \boxed{y=-2x+4}[/tex]
