Explanation:

Think of unwrapping a present and doing so without any unnecessary tearing. That means there aren't any little small pieces thrown away. There are many ways to unwrap a 3D box, and this diagram shows one of many ways. This flat layout is the 2D version of the 3D surfaces.

To find the surface area of the 3D figure, we simply need to find the area of each rectangle in this 2D flat net. Once we know all the little areas, we add them up to get the surface area.

------------------------------

The lowest rectangle is 3 cm by 5 cm, so its area is 3*5 = 15 cm^2. Let A = 15 so we can use it later.

Let's move to the middle row of four rectangles. From left to right, we have these four rectangular areas

I'll call these results B,C,D,E in the order given above. So B = 21, C = 35, etc.

The rectangle up top has area of 3*5 = 15 cm^2. I'll let F = 15

Lastly, we'll add up the sub-areas to get the grand total

A+B+C+D+E+F = 15+21+35+21+35+15 = 142 cm^2 is the surface area

------------------------------

Another pathway to the answer:

If you can picture how this flat diagram would fold up, then you would see that we'd get a 3D block with the following dimensions

The order of L,W,H doesn't really matter.

Then we can use the 3D block surface area formula like so

SA = 2*(LW + LH + WH)

SA = 2*(7*5 + 7*3 + 5*3)

SA = 2*(35 + 21 + 15)

SA = 2*71

SA = 142 cm^2 is the surface area

As you can see from the third step, we have "35", "21" and "15" show up again. The 2 out front is because we have 2 copies of each item mentioned.

Answer:

x-intercept = 14/5

y-intercept = 7/4

Step-by-step explanation:

To find the value of an intercept (x/y) of an equation like this, simply set the other variable to 0 and divide both sides by the coefficient of the variable you're trying to find.

Some form of symetric i think....

The best describes the shape of this distribution is Unimodal symmetric.

A unimodal distribution is a distribution that has one clear peak. The values increase first, rising to a single highest point where they then start to decrease. A unimodal distribution can either be symmetrical or non-symmetrical. A symmetrical distribution is one where the mean, mode, and median are all equal.

Given is a histogram, we have to find the shape of this distribution,

Since, we can see that the graph only has a hump with equal distribution either side of the hump, which can say that the graph is a Unimodal symmetric

Therefore, the given distribution is Unimodal symmetric as the distribution has 1 hump.

hi <3

you can solve this by substituting one equation into the other.

in this case, it is more simple to substitute the first equation into the second, as it is already arranged into a simple format

so:

y + 2y = 6

now you can simplify:

3y = 6

divide both sides by 3 to get your answer:

y = 2

The test of validity is used to determine whether a claim is true or not, based on certain condition(s).

The validity of the given statement is true.

From the question, the given condition is:

Whenever he participates in a race, he is the winner

This can be interpreted as follows:

So, if he is sick; it means that he does not participate in the race and as such he is not the winner.

Hence, the validity of the following statement is true

"Either he participates in the race or he is sick he is not the winner, therefore he is sick​."

Answer:

  the number is 1

Step-by-step explanation:

First of all, you need to know what you're solving. Here, we assume you're trying to find "the number."

__

Let n represent "some number." The given relation can be written using math symbols as ...

  5n +8 = 10 +3n

Subtract 3n +8 from both sides to separate the variable and the constant terms.

  2n = 2

  n = 1 . . . . . . . divide by 2

The number is 1.

Answer:

Step-by-step explanation:

Using an exponential function, it is found that the hourly growth rate of the bacteria culture is of 14.9%.

------------------------

An exponential function has the following format:

[tex]A(t) = A(0)(1+r)^t[/tex]

In which:

------------------------

Since it doubles every 5 hours, it means that:

[tex]A(5) = 2A(0)[/tex]

And we use this to find r.

------------------------

[tex]A(t) = A(0)(1+r)^t[/tex]

[tex]2A(0) = A(0)(1+r)^5[/tex]

[tex](1 + r)^5 = 2[/tex]

[tex]\sqrt[5]{(1 + r)^5} = \sqrt[5]{2}[/tex]

[tex]1 + r = 2^{\frac{1}{5}}[/tex]

[tex]1 + r = 1.149[/tex]

[tex]r = 1.149 - 1 = 0.149[/tex]

0.149*100% = 14.9%.

The hourly growth rate of the bacteria culture is of 14.9%.
