Answer:

x = 8

Step-by-step explanation:

The perimeter of a body is the sum of all its sides.

  Perimeter of the triangle;

       hypothenuse + opposite + adjacent  = x+6 + x + 3 + x + 9 = 3x + 18

  Perimeter of the rectangle  = x+1 + x + 4 + x + 1 + x + 4 = 4x + 10

Now,

 Since their perimeter is equal;

                           3x + 18 = 4x + 10

                             3x - 4x  = 10 - 18

                               -x  = -8

                               x = 8

Answer:

 1728000

Step-by-step explanation:

You always work from the parenthesis first because of order of operation. You have 12( because 2 times 6) then mulitply 12 times 10. You get 120 then you multiply it but itself 3 times. 120 x 120 x 120= 1728000

Step-by-step explanation:

Answer:

−2 is a member of the domain of f.

f(0) > 0

Step-by-step explanation:

Statement 1 is TRUE. Domain value includes set of values of x of the function. -2 is plotted on the x-axis on the graph. Therefore, it is a member of domain of f.

Statement 2 is incorrect. Range includes all possible y-values of the function. On the graph, no y-value plotted is -2. Therefore, -2 is NOT a member of the range of f.

Statement 3 is TRUE.

f(0) is approximately 2.2 on the graph. i.e. at x = 0, y ≈ 2.2.

Therefore, f(0) > 0.

Statement 4 is INCORRECT.

f(2) = 1, that is at x = 2, y = 1 as seen in the graph. Therefore, f(2) is not greater than 2.

Answer: (2,2)

so Using the distance formula,

d = sqrt(x2-x1)^2 +(y2-y1)^2 .

Substituting the values of x and y.

we get,

d = sqrt(-4-8)^2 +(-3-7)^2

d = 2 sqrt 61  

diameter = 2*radius

              = 2 sqrt 61

              = 2 r

              = r

              = sqrt 61

          r^2 = 61  

midpoint of the diameter is:  

Xm= 8-4 / 2

     = 2  

Ym = 7-3 / 2  

     = 2  

Hence,

The center is (2,2)

Answer:

[tex]\huge\boxed{\texttt{480 miles}}[/tex]

Step-by-step explanation:

We can create a ratio here to find the constant of proportionality and use that to find how many miles the plane flew in 4 hours.

We know the plane flew 720 miles in 6 hours. We can create a ratio, represented as a fraction, in the form  [tex]\frac{miles}{hours}[/tex] .

[tex]\frac{720}{6}[/tex]

We can now make another ratio where we use a variable for the miles flown in 4 hours.

[tex]\frac{x}{4}[/tex]

Since the ratios are equal, we can create an equation.

[tex]\frac{720}{6}=\frac{x}{4}[/tex]

To find the value of x, let's cross multiply.

[tex]720 \cdot 4 = 2880\\\\2880\div 6 = 480[/tex]

So the plane flew 480 miles in 4 hours.

Hope this helped!

Answer:

They all have the same degrees

Step-by-step explanation:

Answer:

11.7

Step-by-step explanation:

Answer:

11.7 feet

Step-by-step explanation:

Area finds the length times the width (LxW). In other words, area is how long the first side is multiplied by how wide the second side is. If A=LxW, and we know A is 136, then we know that 136=LxW. This alone isn't enough to find L and W. However, we do know that the patio is a square. Squares have equal sides, so L and W will be the same number. Basically, you need to find the number that equals 136 when it's multiplied by itself. X multiplied by X needs to be 136. You can do this easily with a calculator, if you're allowed to have one. just use the square root function on 136, and be sure to round your answer. If you're not allowed to use a calculator, it's a bit more trial-and-error. Try to see what numbers multiplied by themselves get close to 136, and narrow it down from there (ex. if 11 is too little and 12 is too much, the answer is between 11 and 12). You can also look up video tutorials for how to find a square root without a calculator, or use other study platforms. I hope this helps, and feel free to ask me any questions!! :)

Answer:

He will need 20 3-inch blue tiles

Step-by-step explanation:

Here, the total space to fill is a length of 5.75 ft

The tiles to place at the center has 3/4 ft which is same as 0.75 ft

The length left unfilled will be 5.75 - 0.75 = 5 ft

Now we want to know the number of 3 ft tiles needed to fill up this length;

Mathematically, we know that

1 ft = 12 inches

So 5 ft will be 5 * 12 = 60 inches

So the number of 3 inch tiles needed to fill this length will be 60/3 = 20 tiles

Answer: 144 feet

Step-by-step explanation:

Well solving for area you multiply length times wedth. So multiply 8 and 6 to get 48. Now you have to convert 48 inches into feet. So just multiply 48 times 3 to get 144.

Answer:

x=6.3  :)

Step-by-step explanation:

2(x+4)-6=5x-17

2x+8-6=5x-17

2=3x-17

19=3x

19/3=6.3

Answer:

2(x+4) -6 = 5x-17

2x + 8 - 6 = 5x - 17

8 -6 + 17 = 5x - 2x

2 + 17 = 3x

19 = 3x

divide both side by the coefficient of x which is 3

19/3 = 3x/3

x = 19/3

x = 6 1/3. or 6.33
