The perimeter of a rectangle is 40 inches. The table shows some of the possible dimensions for the length and area of the rectan
Mama L [17]

Answer:

Therefore the Dimensions are

Length =18 inches and Width = 2 inches

OR

Length =2 inches and Width = 18 inches

Step-by-step explanation:

Let the Width of rectangle be 'W' inches.

The length of a rectangle  be 'L' inches.

Area of rectangle given is 36 square inches.

Perimeter of Rectangle is 40 inches.

To Find:

Length = L = ?

Width = W = ?

Solution:

Perimeter of Rectangle is given as

\textrm{Perimeter of Rectangle}=2\times (Length +Width)

Substituting we get

40=2(L+W)\\\\L+W=20\\\therefore L=20-W

We have area of rectangle given as

\textrm{Area of Rectangle}=Length\times Width)

Substituting the given values we get

36=(20-W)\times W\\W^{2}-20W+36=0

Which is a Quadratic Equation, So by Splitting the middle term we get

W^{2}-18W-2W+36=0\\W(W-18)-2(W-18)=0\\(W-2)(W-18)=0\\\therefore W=2\ inches\ or\ W =18\ inches

Therefore the Length will be

L=20-W=20-2=18\ inches\\OR\\L=20-18=2\ inches

Therefore the Dimensions are

Length =18 inches and Width = 2 inches

OR

Length =2 inches and Width = 18 inches

The performance of a cyclist in a race is affected by whether it rains or not that day. The probability the cyclist crashes is 5
ZanzabumX [31]

To solve this problem, we have to consider the fact that if the probability that the cyclist may crash due to some circumstance. The probability the cyclist doesn't crash at any given day is 3/8

<h3>Probability</h3>

The probability the cyclist crash when it's wet or dry will be the

P = P_w_e_t * P_d_r_y

  • P(wet) = 5/8
  • P(dry = 1/8

The probability the cyclist crash on any given day is

P = \frac{5}{8}*\frac{1}{8} =\frac{5}{64}

we can subtract 1 from the value above to find the probability the cyclist doesn't crash at any given day

P = 1 - \frac{5}{64} \\P=\frac{3}{8}

The probability the cyclist doesn't crash at any given day is 3/8
