The answer is 40%. Count how many right triangles there are, there are 20 right triangles. Count how many right triangles are shaded in, there are 8 right triangles that are shaded in. 8/20=0.4 or 40%

How do U dooo this ???

Sloan [31]

Put 10% into a fraction 10/100 = 1/10. Now times 88 KG by 1/10 and you should have the answer.
10% = 10/100 = 1/10

88/1 X 1/10 = 1/20

Find the equation of the exponential function represented by the table below,

jok3333 [9.3K]

Answer:

Graph the exponential function.

$y=-3(8)^{x}$

Step-by-step explanation:

to make a sketch of this graph. We're gonna make a table of values. I think that's probably our best route. So we'll do a couple negative values, but I'm gonna actually start at 08 to 0. Power zero. And I'm sorry. 80 parts one and one times negative. Three is negative. Three eight to the first. Power is eight and eight times negative. Three is negative. 24 8 X squared is 64 64 times negative. Three is on negative. 192. Okay, I think that's plenty. E to the negative. First power is 18 and 1/8 times negative. Three is negative. 3/8 and eight to the negative. To power is 1 64th times negative. Three is negative. 3 60 force. Okay, I think we can see where that's going. Is getting really close to zero. So as faras my graph here, I'm gonna focus on the fourth quadrant, I think. All right. So we got our X and y axis here. We're starting at 01 and to and we'll also do negative one. And negative two aren't horizontally, vertically. I do. I want to scale this whole the way to 1 92 I guess I will. Um, so whatever it is scaled by, maybe twenties. Yeah, let's do that. 20 40 60 8120 40 60 8200. So there's negative. 200? Um, negative. 1 80 Negative 1 60? Nope. That's not right. Because I scaled by twenties didn't. So this is actually negative. 1 60 This one's negative. 1 20 This one's negative. 80. And this is negative. 40. There we go. All right now a plot. These points to negative 1 92 is practically to 200 one. Negative. 24 is all the way over here. Zero negative three is practically on the X axis The way I have this, and same with those fractional values. They're practically on the X axis. So let's start almost parallel to the X axis because it's never actually touch step than its we don't ever. Slowly and then it starts going down rapidly, decreasing in value to the point where it's almost vertical, but it never will get vertical, so there's a decent sketch of y equals negative three times eight to the power of acts

Please answer the equation 5n+1/8=1/2

Mamont248 [21]

$5n^{(8}+\frac{1}{8}=\frac{1}{2}^{(4} \\\\ 40n+1=4 \\\\ 40n=4-1 \\\\ 40n=3\\\\ \boxed{n=\frac{3}{40}}$

find three consecutive odd integers such that the sum of the first and the third equals the sum of the second and 13

andreyandreev [35.5K]

Answer: The three odd integers are 11, 13 and 15.

Step-by-step explanation: The first point to note is that the three unknown numbers are consecutive, which means they follow one after the other. Also we are told that the numbers are consecutive “odd integers.” This also means there is a two-digit interval between one number and the next. Hence, if the first number is A, the next number will be A + 2, and the third number will be A + 2 + 2 (that is, A + 4)

At this point we can now derive the following expressions based on the information we have been given, which is;

The sum of the first and third (A + {A + 4} )equals the sum of the second and 13 ({A + 2} + 13). Therefore we can write this out as follows;

A + {A + 4} = {A + 2} + 13

After removing brackets we now have

A + A + 4 = A + 2 + 13

2A + 4 = A + 15

By collecting like terms we now have

2A - A = 15 - 4

(Remember that when a positive value crosses to the other side of the equation it becomes negative, and vice versa)

2A - A = 15 - 4

A = 11

Hence, the three consecutive integers are 11, 13 and 15.

What is the center of the hyperbola?<br> (1,-2)<br> (1,1) (1,3)<br> (1,6)

Ahat [919]

Answer:

(1, 3)

Step-by-step explanation:

The center of a hyperbola can be found by looking at the midpoint between the two vertices.

Here, the two vertices are (1, 8) and (1, -2). We use the Midpoint Formula to figure out the vertex:

Midpoint is: $(\frac{1+1}{2} ,\frac{8+(-2)}{2} )=(\frac{2}{2} ,\frac{6}{2} )=(1,3)$

Thus, the answer is (1, 3).

Hope this helps!
