N=3 because when you’re multiplying two numbers with a power, you add them to get your answer. so it would be 4^6•4^3=4^9 because 6+3=9, making the only possible value of n, 3.

Find the area of the missing piece of the polygon and explain your process for finding it:
Otrada [13]

Answer:

42

Step-by-step explanation:

In short, the sum of the opposite areas are equal.

x + 30 = 24 + 48

x = 42

To prove this, draw a line from each corner to the "center" where the four lines meet.  Along each side of the square are two triangles.  These triangles have the same base and the same height, and therefore have the same area.

If we say the triangles at the bottom have area a, the triangles on the left have area b, the triangles on top have area c, and the triangles on the right have area d, then we can write 4 equations:

a + b = x

b + c = 24

c + d = 30

a + d = 48

Adding the first and third equations:

a + b + c + d = x + 30

Adding the second and fourth equations:

a + b + c + d = 24 + 48

Therefore:

x + 30 = 24 + 48

x = 42

Round to the nearest tenth wa hit is the perimeter of the triangle
klio [65]

Answer:

D. 11.8 cm

Step-by-step explanation:

This triangle is a 30°-60°-90° triangle. There is a shortcut to find the lengths of the sides of a 30°-60°-90° triangle. The longest side is the hypotenuse. The longest side is double the shortest side or, the shortest side is half the longest side. Here the longest side is 5, so the short leg (shortest side) is 2.5

The other shortcut is that the longer leg is the

short leg×sqroot3

Here, the short leg is 2.5, so the long leg is 2.5×sqroot3

Perimeter is all the sides added together.

5 + 2.5+ 2.5×sqrt3

Do the times first.

5 + 2.5 + 4.3

= 11.8

Is 0.2487 a interger
BabaBlast [244]

No.  0.2487 is not an interger.

There are two big reasons for this:

1).  There is no such thing as an ' interger ',
       so no number could be one.
       You probably mean ' integer '.

2).  An integer is a whole number ... a number
      with no fraction part and no decimal part.
      0.2847  is all decimal, and not even big enough
      to make the smallest whole number.  (That's ' 1 '.)

Zakarya can read 5 pages in 8 minutes <br> How many pages can Zakarya read in 40 minutes?<br> pages
vivado [14]

Answer:

25 pages

Step-by-step explanation:

We know that Zakarya can read 5 pages in 8 minutes. First we divided 40 by 8, to see how many times of 8 she reads. She reads for 8 five times (40 minutes). We can multiply 5 (number of 8 minutes she reads) times 5 (pages she reads every 8 minutes) to get 25. She reads 25 pages in 40 minutes. Please tell me if this is wrong or makes no sense :).
