The length of a rectangle is 3 centimeters less than four times its width. Its area is 10 square centimeters. Find the dimension

Kay [80]

Answer:

W = 2 cm

L = 5 cm

Step-by-step explanation:

A rectangle is a four sided shape with 4 perpendicular angles. It has two pairs of parallel sides which are equal in distance: width and length. Its area, the amount of space inside it, can be found using the formula A = l*w. If the area is 10 cm² and the length is "3 cm less than 4 times the width" or 4w - 3, you can substitute and solve for w.

A = l*w

10 = (4w - 3)(w)

10 = 4w² - 3w

Subtract 10 from both sides to make the equation equal to 0. Then solve the quadratic by quadratic formula.

4w² - 3w - 10 = 0

Substitute a = 4, b = -3 and c = -10.

$w = \frac{3 +/- \sqrt{(-3)^2 - 4(4)(-10)} }{2(4)} = \frac{3 +/- \sqrt{9 +160)} }{8} = \frac{3 +/- \sqrt{169} }{8} = \frac{3+/-13}{8}$

There are two possible solutions which can be found.

3 + 13 / 8 = 16/ 8 = 2

3 - 13 / 8 = -10/8 = -5/4

Since w is a side length or distance, it must be positive so w = 2 cm.

If the width is 2 cm then the length is 4(2) - 3 = 8 - 3 = 5 cm.

Sunny has a six-sided number cube labeled with the numbers 1 through 6 and a spinner, shown below. What is the probability that

Grace [21]

Answer:

$P(Cube \ge 5\ and\ Spin[A]) = \frac{1}{24}$

Step-by-step explanation:

Given

$Cube = \{1,2,3,4,5,6\}$

$n(Cube) = 6$

$Spinner = \{A,B,C,D,E,F,G,H\}$

$n(Spinner) = 8$

See attachment for spinner

Required

$P(Cube \ge 5\ and\ Spin[A])$

On a number cube, we have:

$Cube \ge 5 = \{5,6\}$ ---- i.e. 2 outcomes

So, the probability is:

$P(Cube \ge 5) = \frac{n(Cube \ge 5)}{n(Cube)}$

$P(Cube \ge 5) = \frac{2}{6}$

$P(Cube \ge 5) = \frac{1}{3}$

On the spinner, we have:

$Spin [A] = \{A\}$ ---- i.e. 1 outcomes

So, the probability is:

$P(Spin[A]) = \frac{n(Spin[A])}{n(Spinner)}$

$P(Spin[A]) = \frac{1}{8}$

$P(Cube \ge 5\ and\ Spin[A])$ is calculated as thus:

$P(Cube \ge 5\ and\ Spin[A]) = P(Cube \ge 5) * P(Spin[A])$

$P(Cube \ge 5\ and\ Spin[A]) = \frac{1}{3} * \frac{1}{8}$

$P(Cube \ge 5\ and\ Spin[A]) = \frac{1}{24}$
