What is the volume of the box if it is scaled down by a factor of 1/10?

Answers

Answer 1

I chose a box of cereal-------> rectangular prism

Part 1)List the dimensions of your box. Be sure to include the units (in, cm, ft, etc.).

Length: 20 cm

Width: 8 cm

Height: 32 cm

Part 2).

 Describe the shape of the cross-section when the box is cut parallel to the base

the shape of the cross-section would be a rectangle of dimensions

20 cm x 8 cm

Part 3)

What is the surface area of the box? 

surface area=2*area of the base+perimeter of the base*height

area of the base=20*8=160 cm²

perimeter of the base=2*[20+8]-----> 56 cm

height=32 cm

surface area=2*160+56*32------> 2,112 cm²

the answer part 3) is

2,112 cm²

Part 4)

What is the surface area of the box if it is scaled up by a factor of 10?

we know that

surface area of the larger box=[scale factor]²*surface area original box

scale factor=10

surface area original box=2,112 cm²

so

surface area of the larger box=10²*2,112-----> 211,200 cm²

the answer part 4) is

211,200 cm²

Part 5) 

What is the volume of the box?

volume of the box=L*W*H-----> 20*8*32------> 5,120 cm³

the answer Part 5) is

5,120 cm³

Part 6) 

What is the volume of the box if it is scaled down by a factor of 1/10

we know that

the volume of the smaller box=[scale factor]³*volume original box

scale factor=1/10

volume original box=5,120 cm³

so

volume of the smaller box=[1/10]³*5,120-----> 5.12 cm³

the answer part 6) is

5.12 cm³

The length is⇒ 6 in., the width is⇒ 2 in., and the height is⇒ 16 in.

Do you use the greatest common factor or the least common multiple to add to fractions? In this example what is it? 4/15+5/6

Answers

Answer:

The least common multiple, but you can use the greatest common factor, but at the end you have to simplify for it to be correct. 1 3/30

Step-by-step explanation: 4/15+5/6

Change 15 into a 30 by multiplying 2 to both sides.

Change 6 into a 30 by multiplying 5 to both sides.

so the new fractions are 8/30+25/30=33/30

The final fraction is 1 3/30.

Answers

Answer:

\(y - 100 = \boxed{\:-\dfrac{25}{2} \:} \;\;\left(x -\boxed{\:4\:}\:\right)\)

Step-by-step explanation:

The first thing to observe is that the balance declines at a linear rate with respect to time in weeks

The given equation which you have to fill in is in the point-slope form of a straight line

The point slope equation of a straight line is
y - y1 = m(x - x1)

where (x1, y1) is a point on the line
m is the slope = (x2 - x1)/(y2 - y1) with (x1, y1) and (x2, y2) being two points on the line

To find the slope,

Let's take two points say 4, 100) and (8,50) where the first entry is the weeks and second is the current balance

Slope m = (50 - 100)/(8 - 4) = - 50/4 = -25/2

The negative value simply indicates that the balance is declining by 25/2 every two weeks

Having got the slope we can rewrite the equation as

y - y1 = -25/2(x - x1)

Again take (x1, y1) as (4, 100) to get

\(y - 100 = \boxed{-\dfrac{25}{2}} (x -\boxed{ 4})\)

And this is the answer

Help: The stem-and-leaf plot displays the distances that a heavy ball was thrown in feet.

4 1, 1, 5
5 0, 6
6 7
Key: 3|1 means 3.1

What is the mean, and what does it tell you in terms of the problem?
A.3.1 feet; The value means the furthest the ball went.
B.3.875 feet; The value means that a typical throw of the ball results in 3.875 feet.
C.4.1 feet; The value means this measurement had the most occurrences.
D.4.65 feet; The value means that a typical throw of the ball results in 4.65 feet.

Answers

Answer: B) 3.875

Step-by-step explanation:

To start off, finding the mean is the AVERAGE. To find the average, you must add all of the values, and divide by however many values there are (in this case, there are 12) So first add all of the values:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

2+2.2+2.5+3.1+3.3+3.4+4.1+4.1+4.5+5+5.6+6.7 = 46.5 (or 46.50)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

next, you divide 46.5 by however many values there are (in this case, there are 12)

So, 46.5 / 12 is equal to 3.875

This tells us that the average distance of the throw is 3.875 feet

Therefore, the correct answer is B.3.875 feet; The value means that a typical throw of the ball results in 3.875 feet.

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.

cassie is placing stickers on a page that is 12 inches long and 8 inches wide the sticker are 3 inches long and 2 inches wide

cassie is placing stickers on a page that is 12 inches long and 8 inches wide the sticker are 3 inches

Answers

Answer:

To find the greatest number of stickers Cassie can place on a page that is 11 inches long and 8 inches wide without them overlapping, we need to use the same approach as before.

Firstly, we need to calculate the maximum number of stickers that can fit along the length of the page, which is now 11 inches. Since each sticker is 3 inches long, we can fit 3 stickers along the length (11 ÷ 3 = 3 with a remainder of 2).

Next, we can calculate the maximum number of stickers that can fit along the width of the page, which is still 8 inches. Since each sticker is 2 inches wide, we can fit 4 stickers along the width (8 ÷ 2 = 4).

To ensure that the stickers do not overlap, we can only use the full row of 3 stickers from the previous calculation. Therefore, we can place 3 stickers along the length and 4 stickers along the width, giving us a maximum of 12 stickers that Cassie can place on the page without them overlapping.

Step-by-step explanation:

Answer:

16

Step-by-step explanation:

First, find out how much stickers you can put on the long side:

12/3 = 4

Next, find out how much stickers you can put on the wide side:

8/2 = 4

Lastly, calculate them together:
