Answer:

60

Step-by-step explanation:

Let the side of the square (s) = 3x

Then a rectangle is 3x long and x wide

  P = 2l + 2w

40 = 2×3x + 2x = 6x +2x = 8x

x = 40/8 = 5

For the square,  

s = 3x = 3 ×  5 = 15

P = 4s = 4 × 15 = 60

The perimeter of the square is  60.

Monet measures the diameter of an Oreo and finds that each cookie is 1.75 inches across. Using Monet's measurement, calculate th
Anon25 [30]

Answer:

5.495 inches.

Step-by-step explanation:

We have been given that Monet measures the diameter of an Oreo and finds that each cookie is 1.75 inches across. We are asked to find the circumference of an Oreo.

We know that circumference of circle is equal to 2\pi r, where r represents radius of circle.

We also know that diameter is 2 times radius.

D=2r

Upon substituting 2r=\text{ 1.75 in}, we will get:

\text{The circumference of an Oreo}=\text{ 1.75 in}\times \pi

Using 3.14 as an estimation for π, we will get:

\text{The circumference of an Oreo}=\text{ 1.75 in}\times 3.14

\text{The circumference of an Oreo}=5.495\text{ in}

Therefore, the circumference of an Oreo would be 5.495 inches.

What is the value of x
FromTheMoon [43]

Answer:

x = 32

Step-by-step explanation:

this is an equilateral triangle where all sides measure the same value; therefore, 2x-4 = 5y

since we are solving for 'x' we can set up this equation:

3(2x-4) = 180

6x - 12 = 180

6x = 192

x = 32

Find EC help me please
kow [346]
Ok to find this answer you first have to subtract the 16 from the 30 to find what "CB" is, which is 14. From there subtract 14 and 16 from 49 to find that the whole answer is 35. I think that is the answer but I'm not positive.
