Answer:

  138.16 in²

Step-by-step explanation:

The surface area SA of the cone is the sum of the base area B and the lateral area LA. The lateral area is half the product of the circumference and the slant height. The radius is half the diameter, so is 4 inches.

  SA = B + LA

  = πr² + (1/2)(2πrh) . . . . where h is the slant height

  = (πr)(r +h)

Filling in the numbers, you have ...

  SA = (3.14)(4 in)(4 in + 7 in) = 3.14×(44 in²) = 138.16 in²

How can a ratio's number can be changed without changing the ratio itself
eimsori [14]
<h2>Answer:</h2>

The ratio is a fraction that tells us how many times longer a thing is compared to another thing. In mathematics, we express a ratio as the relationship between two numbers, namely a \ and \ b, so the ratio can be written as:

r=\frac{a}{b}

If we can change this number without changing the ration we need to multiply  both the numerator and the denominator by the same number. For instance, if we have the following ratio:

r=\frac{2}{3}

We can multiply both the numerator and denominator, say, by 7. Then:

r=\frac{7\times 2}{7 \times 3}=\frac{14}{21}

As you can see, the ratio's number has changed but without changing the ratio itself because:

\frac{2}{3}=\frac{14}{21}

In a function, y varies inversely with x. The constant of variation is 4. Which table could represent the function?
Colt1911 [192]
I don't see a table but I can give you the means to answer it yourself.  The inverse function is represented by this: y= \frac{k}{x} where k is your constant.  You are given a k value of 4.  If you solve this for k then you will get xy=4.  In your tables, multiply your x value by your y value within your coordinate points and if you get a product of 4 each time you multiply x by y, then that table is your answer.

When two people each measured a windows width, their results were 79 cm and 786 mm. Are these results equally precise? Explain.
rosijanka [135]

The second result is more precise because it's in millilitre,so if the first were to be fully precise,it should have been 78.6 cm.

Hope this helps!

How many solutions does the equation have?
snow_lady [41]

5(n - 2) = 5n - 10 \\  \\ 5n - 10 = 5n - 10 \\  \\ 5n - 10 + 10 = 5n - 10 + 10 \\  \\ 5n = 5n \\  \\

Infinite solutions. This equality is true for any value of n.
