Step-by-step explanation:

Formula: v = πr²[tex]\frac{h}{3}[/tex], v = πr²h

Given: π = 3.14, r = 3, h = 5

Sub: 3.14(3)²[tex]\frac{5}{3}[/tex]

Simplify: 3.14(9)[tex]\frac{5}{3}[/tex]

Simplify: (28.26)[tex]\frac{5}{3}[/tex]

Solve: 47.1

Given: π = 3.14, r = 3, h = 6

Sub: 3.14(3)6

Simplify: (9.42)6

Solve: 56.52

V = v1 + v2

V = 47.1 + 56.52

V = 103.62

The total volume of the figure is 103.62

0.512 = 51.2%

1.94 = 194%

0.9 = 90%

1.33 = 133%

1.14 = 114%

1.42 = 142%

Step-by-step explanation:

 To convert a decimal to a percent, move the decimal point two spaces to the right.

 Converting a percent to a decimal works the same way, except you move the decimal two spaces to the left.

[Note: If there aren't enough numbers to go over two spaces, place a zero at the end. For example, if you have 0.9, and you need to convert it into a percent, you'd place a zero after the 9, making it 0.90.]

The true condition is A. SU+UT= RT.

We have given that,

A line contains the following points left to right: R, T, U, S. The space between R and T is 12 units. The space between R and S is 24 units.

If TU = 6 units,

We have to determine the true statement,

Answer:

Amount invested = $15,000 (Approx.)

Step-by-step explanation:

Given:

Amount of interest received = $6,159

Rate of interest = 3.5%

Number of year = 10 year

Find;

Amount invested

Computation:

Using compound interest formula

I = P[(1+r)ⁿ - 1]

6,159 = Amount invested[(1+3.5%)¹⁰ - 1]  

6,159 = Amount invested[(1+0.035)¹⁰ - 1]  

6,159 = Amount invested[(1.035)¹⁰ - 1]  

Amount invested = $15,000 (Approx.)

Answer:

C. 22 mph

Step-by-step explanation

Assign the speed of the freight train as; x mph

Since the passenger train travels 6 mph faster than the freight train, its speed will be; (x + 6) mph

In 2 hours, the freight and passenger trains will have traveled (distance = speed * time);

2x and 2(x + 6) miles respectively

Both add up to 100 miles. Therefore;

2x + 2(x +6) = 100

4x + 12 = 100

4x = 88

x = 22

x + 6 = 28

Answer:

Option B

Step-by-step explanation:

It's given that p + q has a value of [tex]\frac{12}{5}[/tex]

So the equation representing the relation will be,

p + q = [tex]\frac{12}{5}[/tex] --------(1)

Value of p is [tex]\frac{4}{5}[/tex]

p = [tex]\frac{4}{5}[/tex]

By substituting the value of p in the equation (1),

[tex]\frac{4}{5}+q=\frac{12}{5}[/tex]

q = [tex]\frac{12}{5}-\frac{4}{5}[/tex]

q = [tex]\frac{8}{5}[/tex]

Therefore, Option B will be the correct option.

Answer:

[tex] \boxed{A ≈ 58.1 \: cm^{2}} [/tex]

Step-by-step explanation:

When given a regular polygon.

s = a × 2 tan (π / n [radians]).

s = a × 2 tan (180 / n [degrees])

A = (n × s × a) / 2

Where s is the side length, n is the number of sides, a is the apothem length, and A is the area.

You may also see A = p × a.

Where p is the perimeter, the perimeter is the same as n × s.

The apothem is also known as the inradius.

______________________________________

Given a regular pentagon which has 5 sides, and an apothem of 4 cm.

s = 4 × 2 tan (180 / 5) = 4 × 2 × (0.726542528) = 8 × (0.726542528) = 5.81234022404.. ≈ 5.8 cm.

Now that we have sufficient information, we can now solve for the area.

A = (n × s × a) / 2

A = (5 × 5.81234022404.. cm × 4) / 2

A = (20 × 5.81234022404.. cm) / 2

A = (116.236804481.. cm²) / 2

A = 58.1234022404.. cm²

A ≈ 58.1 cm²

The area of the regular polygon is the amount of space it covers

The area of the regular polygon is 58.1 square centimeter

The given parameter is:

[tex]\mathbf{a=4}[/tex]

Start by calculating the side lengths using

[tex]\mathbf{s = 2a\ tan (\frac{180}{ n} )}[/tex]

Where n represents the number of sides.

In this case

[tex]\mathbf{n =5}[/tex]

So, we have:

[tex]\mathbf{s = 2a\ tan (\frac{180}{ 5} )}[/tex]

[tex]\mathbf{s = 2a\ tan (36)}[/tex]

Substitute 4 for (a)

[tex]\mathbf{s = 2 \times 4\ tan (36)}[/tex]

[tex]\mathbf{s = 8\ tan (36)}[/tex]

[tex]\mathbf{s = 5.8123}[/tex]

The surface area is then calculated as:

[tex]\mathbf{A = \frac{n \times s \times a}{ 2}}[/tex]

So, we have:

[tex]\mathbf{A = \frac{5 \times 5.8123 \times 4}{2}}[/tex]

[tex]\mathbf{A = 58.123}[/tex]

Approximate

[tex]\mathbf{A = 58.1}[/tex]

Hence, the area of the regular polygon is 58.1 square centimeter

Answer:

The dimension of the sandbox is (2x+1) by (x - 3)

Step-by-step explanation:

It seems the complete question will be:

The area of sandbox in park is represented by 2X^2-5x-3 find the dimensions of the sandbox in terms of x.

Step-by-step explanation:

From the question, the given expression is 2X^2-5x-3. This can be rewritten as

[tex]2x^{2} -5x-3[/tex]

If the area of the sandbox in park is represented by this expression, then the dimensions of the sandbox will be the product of the factors. To determine the factors, we will factorize the given quadratic expression.

Factorizing the expression [tex]2x^{2} -5x-3[/tex], we get

[tex]2x^{2} -6x+x-3[/tex]

[tex]2x(x-3)+1(x-3)[/tex]

[tex](2x+1)(x-3)[/tex]

Hence, the dimension of the sandbox is (2x+1) by (x - 3)
