Please solve with explanation I’ve been asking for awhile

Michaela is making memory boxes. She wants to cover the boxes with sheets of decorative paper on all sides before filling them.

Answer:

area = 5220 in²

Step-by-step explanation:

It's a little difficult to ensure accuracy without a diagram of the net, but from what you have said, the net appears to comprise of:

2 rectangles: 35 x 24
2 rectangles: 24 x 30
2 rectangles: 35 x 30

Therefore, the total area of the net is:

⇒ area = 2(35 x 24) + 2(24 x 30) + 2(35 x 30)

⇒ area = 5220 in²

The Skittles jar has a radius of 3.5 cm and a height of 11.5 cm. Using the two given boxes for reference what would be a good es

nevsk [136]

Answer:

1052

Step-by-step explanation:

The two given boxes for reference are presented below.

Since we know the dimensions of the first container, we can calculate its volume.

$V_1= 5 \text{cm} \cdot 4 \text{cm} \cdot 4 \text{cm} = 80 \text{cm}^3$

The first container held 192 skittles. Using that fact, now that we know the volume of the first box, we can calculate the volume of a single skittle.

$v = \frac{80}{192} = 0.416 \approx 0.42 \text{cm}^3$

The second container held 258 skittles.

The volume of the second box is:

$V_2 = 12 \text{cm}\cdot 3 \text{cm} \cdot 3 \text{cm} = 108 \text{cm}^3$

Using this facts, the volume of a single skittle would be

$v = \frac{108}{258} = 0.418 \approx 0.42 \text{cm}^3$

Therefore, the volume of single skittle is around to 0.42 cm³.

A skittle jar is a cylinder. Its volume is calculated by the formula

$V = r^2h \pi$ ,

where $r$ is the radius and $h$ is the height. From the given data, we have $r = 3.15 \text{cm}$ and $h = 11.5 \text{cm}$ . Hence, the volume of the jar is

$V = 3.5^2 \cdot 11.5 \cdot 3.14 = 442 \text{cm}^3$

Now, we can determine the number of skittles in the jar. Let $n$ be the number of skittles in the jar. Then,

$n = \frac{\text{volume of the jar}}{\text{volume of a skittle}} = \frac{V}{v} = \frac{442}{0.42} = 1052.38 \approx 1052\\$

25 POINTS HELP PLEASE! Complete the table and pattern. Determine the common difference. Write the explicit rule.

Mumz [18]

Answer:

Look below for the answers.

Step-by-step explanation:

What I'm going to do is one of these very carefully and leave the other 2 to you. They follow exactly the same pattern and once you see one of them done, you should be able to do any of them.

Six

Step one

Find the common difference.

Two values on the second line are always together so subtract the higher number one from the lower numbered on.

n = 3 and n = 4 on this question are side by side. That is you have f(4) and f(3)

ALWAYS subrract the lower numbered one from the higher numbered one

d = f(4) - f(3) = 60 - 64 = - 4

Step Two

Find the first term.

The first term is ALWAYS f(1). Always. There is never any kind of exception. f(1) in this case is 72

Step Three

Write the general explicit term

The general formula for the explicit Formula is ALWAYS

tn = first term + (n -1)*d

first term = 72

d = - 4 from above.

Explicit formula = 72 + (n - 1)*(-4) So the fifth term is

Example

t5 = 72 + (5 - 1)*(-4)

t5 = 72 + 4*(-4)

t5 =72 - 16

t5 = 56

Step Four

Write the Recursive formula

It is always in the same formal

tn = t_(n - 1) + (common difference)

tn = t_(n - 1) - 4 in this case

Example

Find t2

t2 = t1 - 4

t2 = 72 - 4

t2 = 68

If you do the other two, you can leave them in my PM and I will mark them.
