Free_Kalibri [48]

Answer:

21 = n

Step-by-step explanation:

5 - \frac{1}{3}n = -2

-5 - 5

________________

-⅓<em>n</em> = -7

____ __

-⅓ -⅓

21 = <em>n</em>

* Dividing by a fraction is the exact same as multiplying by its <em>multiplicative</em><em> </em><em>inverse</em>:

\frac{-7}{-\frac{1}{3}} = -7 \times -3 = 21

Katen [24]

Answer:

#7 = 53.41

#8 = 18.85

#9 = 87. 96

Step-by-step explanation:

The formula for Circumfrance of a circle is: C=2 π r

So lets do #7:

17/2 (the radius is 1/2 of the diameter)

R= 8.5 (now plug in)

C= 2 π 8.5

C=17π

Now repeat on 8 and 9

8:

C= 2 π 3

C=6π

c= 18.85

9:

C= 2 π 14

C= 28π

C= 87.96

BRAINLIEST FOR RIGHT ANSWER!! A student wants to know how many 1 cm squares are needed to completely cover all the sides of a 10
drek231 [11]
Surface area, but there is a wrinkle which we'll talk about later.

The area is front and back top and bottom left and right, six sides in all. 

Left / Right
Area = 10 * 8 = 80 cm^2
2 Sides Area = 2 * 80 cm^2 = 160 cm^2

Top / Bottom
Area = 10 * 12 = 120
2 Side Area = 2 * 120 = 240 cm^2

Ends
Area = 8 * 12 cm = 96 cm^2 
2 sides = 2 * 96 = 192 cm^2

Total Area
The total area of all six sides is 192 + 240 + 160 = 592 cm^2

Comment and Answer
592 cm^2 <<<< Answer

There might be a problem with overlap. Right at the edge of face the gluing of the tiles stops. Do you put on one more layer or not. I would say not. You have to be told to do that. I think the question just requires a straight forward reply. If not, write me a message.

What's meant by the derivative of a function ?!
chubhunter [2.5K]
Measures how quickly the position of the object changes when time advances.
The derivative of a function of a single variable at a chosen input value, when it exists, is the slope of the tangent line to the graph of the function at that point. The tangent line is the best linear approximation of the function near that input value
