Answer:

70 inches

Step-by-step explanation:

Finding the perimeter of a rectangle means taking two sides of the same length and adding them to two sides of a seperate length. 20 times two is 40, 180 minus 40 is 140, 140 divided by two is 70. Meaning that the length of the rectangle must be 70 for the width to be 20 and the perimeter to be at least 180 inches.

20x2 = 40 in width
180-40= 140
140/2=70
70 inches

okay so the problem here is i just am not able to do a simple math :'( my nutrition label says 100 grams of mushrooms contain 1.
bearhunter [10]
Solution:
if 100 gram mushroom contains 1.2 gram carbs
then,
1 gram mushroom contains 1.2/100=0.012 gram of carbs
then,
25 gram mushroom contains
25*0.012 gram of carbs=0.3
to check,
100/4=25
25 grams contains 0.3 gram carbs
100 gram contains 4*0.3=1.2 gram carbs(which is given)

Consider two triangles with side lengths √8, √32, and √40.
iragen [17]

Using the Pythagorean Theorem, the approximate values for x and y are given as follows:

c. x = 5.66, y = 8.

<h3>What is the Pythagorean Theorem?</h3>

The Pythagorean Theorem relates the length of the legs l_1 and l_2 of a right triangle with the length of the hypotenuse h, according to the following equation:

h^2 = l_1^2 + l_2^2

From the triangle to the right, we have that:

  • The sides are x and \sqrt{8}.
  • The hypotenuse is of \sqrt{40}.

Hence:

x^2 + (\sqrt{8})^2 = (\sqrt{40})^2

x² + 8 = 40

x² = 32

x = sqrt(32)

x = 5.66.

From the triangle to the right, we have that:

  • The sides are both of \sqrt{32}.
  • The hypotenuse is of y.

Hence:

y^2 = (\sqrt{32})^2 + (\sqrt{32})^2

y² = 32 + 32

y² = 64

y = sqrt(64)

y = 8.

Hence option c is correct.
