Silver has a density of 0.04 lb/cm^3. A standard silver bar has a volume of 642
cm^3. To the nearest pound, how much does 1 standard silver bar weigh?

Answers

Answer:

The weight of the mentioned silver bar is:

25.68 Lb

Step-by-step explanation:

Remember that the formula of density is:

Density = mass / volume.

From this formula, you can clear the mass (because this is the valor you need to solve the exercise), so you will have:

Mass = density * volume

With this last formula, you must replace the values given in the exercise:

Mass = density * volume Mass = 0.04 lb/cm^3 * 642  cm^3 Mass = 25.68 Lb

You can check this value using the original formula of density and see if the density has the same valor of the exercise:

Density = mass / volume. Density = 25.68 Lb / 642 cm^3 Density = 0.04 Lb / cm^3

Type the correct answer in the box.Points A, B, C, and D represent the four corners of a parade route.

Answers

Answer: I think it's 72 kilometers

Step-by-step explanation:

I am not really sure?????

The total distance that John’s float travels is 71.02 kilometers.

What is distance formula?

The distance formula which is used to find the distance between two points in a two-dimensional plane is also known as the Euclidean distance formula. On 2D plane the distance between two points (x1, y1) and (x2, y2) is Distance = √[(x2-x1)²+(y2-y1)²].

Given that, John’s float goes from point A to B, then to C, then to D, and back to A.

Here, DC =9 kilometers, AD=9 kilometers

A(-7, 5) and B(3, 2)

AB=√[(3+7)²+(3-5)²]

=√109

= 10.44 kilometers

B(3, 2) and C(2, -4)

So, BC =√[(2-3)²+(-4-3)²]

= √50

= 7.07

Now, distance =10.44+7.07+9+9

= 35.51 kilometers

If he repeats this route twice, the total distance that his float travels is

kilometers.

The total distance =2×35.51

= 71.02 kilometers

Therefore, the total distance that John’s float travels is 71.02 kilometers.

Answer:

1. 678.6

2. 1131

3. 490.1

4. 1809.6

Step-by-step explanation:

A=2πrh+2πr2

Answer:

1.  SA = 216π cm² ≈ 678.24cm²

2. SA = 360π ft²≈ 1130.40ft²

3. SA = 156π yd² ≈ 489.84yd²

4. SA = 576π m² ≈ 1808.64 m²

Step-by-step explanation:

SA of a cylinder = 2πrh + 2πr²

1.  r = diameter ÷ 2

  r = 12/2 = 6

   SA = 2π(6)(12) + 2π(6)²

   SA = 144π + 72π

   SA = 216π ≈ 678.24

2. r = 19/2 = 9

   SA = 2π(9)(11) + 2π(9)²

   SA = 198π + 162π

   SA = 360π ≈ 1130.40

3.  SA = 2π(6)(7) + 2π(6)²

    SA = 84π + 72π

    SA = 156π ≈ 489.84

4. r = 24/2 = 12

    SA = 2π(12)(12) + 2π(12)²

    SA = 288π + 288π

    SA = 576π ≈ 1808.64

Answer: 23.04

Step-by-step explanation:

2.0*2.0= 4.0

2.4*2.4= 5.76

4.0*5.76= 23.04

Answer: The area of the given shape is 9.734 meter square

Step-by-step explanation:

The given shape is a square with 4 sides of equal dimensions "a",

Area of Square = Square of its side "a"

Here, a = Hypotenuse of the inner triangle

Step 1: Get the hypotenuse value of the inner right triangle as the base and height dimensions of the right triangle is given.

Step 2: By using Pythagoras theorem,

Square of the base + Square of the height = square of the Hypotenuse

(2.4)^2 + (2.0)^2 = 9.76

Therefore the value of the hypotenuse = 3.12m

The area of the square = 9.734 meter square.

And its 0.2 And it grows to 0.8

Please help me

Answers

Answer:

The scale factor is 4, which represents an enlargement. And it grows from 0.25 to 0.8.

Step-by-step explanation:

The original hexagon has been enlarged by a scale factor of 4, meaning that each length and width of the original hexagon has been multiplied by 4. This means that the dimensions of the second hexagon are 4 times larger than the dimensions of the first hexagon.

In this case, the original side length of 0.25 has been multiplied by 4, resulting in a new side length of 0.25 * 4 = 1. This represents an enlargement of the original hexagon, since all dimensions have increased.

To summarize, the first hexagon has been scaled up by a factor of 4 to form the second hexagon, resulting in an enlargement of the original shape. The side length of the original hexagon has increased from 0.25 to 0.8, which represents the growth of the hexagon.

Mackey invested some money in an account paying 6% interest for one year. She invested $1000 more than this amount in an account paying 8.5%. How much did she invest in total if the total interest earned in the year was $737.50?

Answers

Step-by-step explanation:

Let's assume the amount Mackey initially invested in the 6% account is x dollars.

According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.

The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.

The total interest earned in the year is given as $737.50, so we can set up the equation:

0.06x + 0.085(x + $1000) = $737.50

Simplifying the equation:

0.06x + 0.085x + 0.085($1000) = $737.50

Combining like terms:

0.145x + $85 = $737.50

Subtracting $85 from both sides:

0.145x = $737.50 - $85

0.145x = $652.50

Dividing both sides by 0.145:

x = $652.50 / 0.145

x ≈ $4500

Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.

$4500

$4500

$4500

$4500

-3 (x- 4/5) ≤ 6 solve step by step

Answers

To solve for x, we need to isolate x on one side of the inequality. We can start by distributing the -3 on the left side of the inequality.

-3x + 12/5 ≤ 6

Next, we can subtract 12/5 from both sides of the inequality to isolate the variable term on the left side.

-3x ≤ 6 - 12/5

Simplifying the right side of the inequality:

-3x ≤ 30/5 - 12/5
-3x ≤ 18/5

Finally, we can divide both sides of the inequality by -3. Since we are dividing by a negative number, we need to reverse the direction of the inequality.

x ≥ -18/15

Simplifying:

x ≥ -6/5

Therefore, the solution for the inequality is x ≥ -6/5.
-3(x - 4/5) ≤ 6

Distribute the -3:

-3x + 12/5 ≤ 6

Subtract 12/5 from both sides:

-3x ≤ 6 - 12/5

Find a common denominator:

-3x ≤ 30/5 - 12/5

-3x ≤ 18/5

Divide by -3, remembering to flip the inequality since we are dividing by a negative number:

x ≥ -18/15

Simplify:

x ≥ -6/5

The circumference of a circular park is approximately 18 feet. What is the approximate area inside the circular park?

Answers

Answer:

25.685 square feet.

Step-by-step explanation:

Circumference = 2 * π * radius

From this, we can derive the formula for the radius:

radius = Circumference / (2 * π)

Let's substitute the value of the circumference and calculate the approximate radius:

radius = 18 / (2 * π)

radius ≈ 18 / (2 * 3.14159)

radius ≈ 2.865 feet

Now that we have the approximate radius, we can calculate the area:

Area ≈ π * radius²

Area ≈ 3.14159 * (2.865)²

Area ≈ 3.14159 * 8.193225

Area ≈ 25.685 square feet

Therefore, the approximate area inside the circular park is approximately 25.685 square feet.

We know that the circumference of a circle is given by:

C = 2πr

where C is the circumference and r is the radius of the circle.

In this case, we are given that the circumference is approximately 18 feet, so we can set up the following equation:

18 = 2πr

Solving for r, we get:

r = 9/π ≈ 2.864 feet

Now we can use the formula for the area of a circle:

A = πr^2

Substituting the value we found for r, we get:

A = π(2.864 ft)^2 ≈ 25.85 ft^2

Therefore, the approximate area inside the circular park is approximately 25.85 square feet.
