Step-by-step explanation:

step 1. a circle has an area, A, of 81(pi)

step 2. A = (pi)r^2 = 81(pi)

step 3. therefore r^2 = 81 or r = 9

step 4. if the radius is 9 inches then the diameter is 18 inches.

Answer:

When the force exerted by one team slackens, the force exerted by their third law, each team pulls the opposite team with equal force in a tug of war.  So the two forces don't balance each other and the rope accelerates towards the stronger team.

Answer:

so on the first one all your doing is multiplying 65 by the number on top so the graph should look like this.

2 3 4 5

130 195 260 325

On the second one all your doing is putting the dot where the numbers meet up so for example. I'm going to try my best at this to create a drawing so pretend ! is a line and - is also a line.

10!

so I hope this made sense so where I put my dot is where the blue dot should go on the graph

Answer:

SAS stands for "side, angle, side" and means that we have two triangles where we know two sides and the included angle are equal. If two sides and the included angle of one triangle are equal to the corresponding sides and angle of another triangle, the triangles are congruent.

Answer:

16.65

Step-by-step explanation:

15 percent of 111 is the same as 15 per hundred of 111. We can therefore make the following equation:

15/100 = X/111

To solve the equation above for X, you first switch the sides to get the X on the left side, then you multiply each side by 111, and then finally divide the numerator by the denominator on the right side to get the answer. Here is the work to illustrate:

15/100 = X/111

X/111 = 15/100

X*111/111 = 15*111/100

X = 1665/100

X = 16.65

or

The work above shows the long way to explain how to calculate 15 percent of 111 in order to give you a foundation and better understanding of how to calculate percentage. In the future, you could use this simplified formula:

(Y * P)/100

In our problem "What is 15 percent of 111?", Y is 111 and P is 15:

(111 * 15)/100 = 16.65

And once again you see that the answer is 16.65.

Answer:

740

Step-by-step explanation:

If we substitute "what number" in the question "111 is 15 percent of what number?" with 740, we get this sentence: 111 is 15 percent of 740. Since this statement is true, we know that our answer is correct.

Following shows the steps on how to derive this formula

Step 1: If 15% of a number is 111, then what is 100% of that number? Setup the equation.

111          Y

------  =   -------

15         100%

Step 2: Solve for Y

Using cross multiplication of two fractions, we get

15Y = 111 x 100

15Y = 11100

Y = 11100

100 = 740

Formula = Number x 100     111 x 100

                 --------------------- = ------------  = 740

                   Percent              15

Answer:

-6 and -1

Step-by-step explanation:

let's suppose there are two numbers x and y so that it that works that would give the following equations

[tex]x*y=6 \\ x+y =-7[/tex]

now let'S rewrite the first to the form y =

[tex]y=\frac{6}{x}[/tex]

and plug that into the second one

[tex]x+\frac{x}{6} = -7|*6\\6x+x=-42\\7x=-42|:7\\x=-6[/tex]

use that to find out what y is

[tex]-6+y=-7|+6\\y=-1[/tex]

you can check that with the first equation

Answer:

The Liberty Tree (1646–1775) was a famous elm tree that stood in Boston near Boston Common, in the years before the American Revolution. The tree became a rallying point for the growing resistance to the rule of Britain over the American colonies, and the ground surrounding it became known as Liberty Hall. By hanging the noose there it is symbolizing liberty and justice is served.

Answer:

y = 10x

Step-by-step explanation:

Independent variable (x) = time (minutes)

Dependent variable (y) = distance (feet)

The line passes through the point of origin (0, 0), which means it represents a proportional relationship. Therefore, the equation would be in the form of y = mx. Where,

m = slope = y/x

Using any point on the line, say (5, 50),

m = 50/5

m = 10

To write the equation, substitute m = 10 into y = mx

Thus:

y = 10x

Answer:

Step-by-step explanation:

Graph given in the attachment represents a linear function f(x).

y = -f(x) represents the reflection of the graph across x-axis.

Therefore, y-coordinates of the points on the graph will get opposite notation after the reflection across x-axis.

Points on the graph of function f(x) are,

(0, -2), (2, 0), (4, 2) and (5, 1)

Therefore, points for the graph y = -f(x) will be,

(0, 2), (2, 0), (4, -2) and (5, -1)

Now we can plot these points to get the graph of y = -f(x)

Answer:

The answer is below

Step-by-step explanation:

The slope of a line passing through two points [tex](x_1,y_1)\ and\ (x_2,y_2)[/tex] is given by:

[tex]slope(m)=\frac{y_2-y_1}{x_2-x_1}[/tex]

The slope of triangle ABC is gotten by finding the slope of line AC. Line AC passes through the point A(15, 1) and C(10, 3). The slope of triangle ABC is given by:

[tex]slope\ of\ triangle\ ABC=\frac{3-1}{10-15}=-0.4\\[/tex]

The slope of triangle AGH is gotten by finding the slope of line AH. Line AH passes through the point A(15, 1) and H(0, 7). The slope of triangle AGH is given by:

[tex]slope\ of\ triangle\ AGH=\frac{7-1}{0-15}=-0.4\\[/tex]

Since both triangles have the same slope, therefore their steepness is the same.

Answer:

7.4

Step-by-step explanation:

solve for side a in first triangle:

[tex]10^2-6^2=y^2[/tex]

100-36=[tex]\sqrt{64}[/tex] (take square root of 64)

y=8

then use 8 to solve for x:

[tex]8^2-3^2=x^2[/tex]

64-9=[tex]\sqrt{55}[/tex] (take square root of 55)

x=7.4
