The length of a rectangle is 3 1/6 cm longer than the width. The perimeter of the rectangle is 15 1/3 cm. What are the width and

ahrayia [7]

The width of rectangle is $2\frac{1}{4}$ cm and length is $5\frac{5}{12}$ cm.

Step-by-step explanation:

Let,

Width of rectangle = w

Length of rectangle = $w+3\frac{1}{6}=w+\frac{19}{6}$

Perimeter of rectangle = $15\frac{1}{3}=\frac{46}{3}$ cm

Perimeter = 2(Length + Width)

$\frac{46}{3}=2(w+\frac{19}{6}+w)\\\\\frac{46}{3}=2(2w+\frac{19}{6})\\\\\frac{46}{3}=4w+\frac{19}{3}\\\\4w+\frac{19}{3}=\frac{46}{3}\\\\4w=\frac{46}{3}-\frac{19}{3}\\\\\ 4w=\frac{46-19}{3}\\\\4w=\frac{27}{3}\\\\4w=9$

Dividing both sides by 4

$\frac{4w}{4}=\frac{9}{4}\\\\w=\frac{9}{4}$

Width of rectangle = $\frac{9}{4}=2\frac{1}{4}\ cm$

$Length = w+\frac{19}{6}=\frac{9}{4}+\frac{19}{6}\\\\Length = \frac{27+38}{12}=\frac{65}{12}\\\\Length=5\frac{5}{12}\ cm$

The width of rectangle is $2\frac{1}{4}$ cm and length is $5\frac{5}{12}$ cm.

A card is drawn randomly from a standard 52-card deck. Find the probability of the given event. (a) The card drawn is 5. The pro

Dmitrij [34]

Answer:

a. 1 / 13
b. 3 / 13
c. 10 / 13

Step-by-step explanation:

There are four 5's in the deck. This means that, from 52 possible cards to drawn, we have 4 chances of drawing a 5. This means that the probability will be:

$p = \frac{4}{52}$

$p = \frac{1}{13}$

For every suit, there are three face cards, J, Q and K. There are 4 suits, so, the total number of face cards its:

$4 * 3 = 12$

The total possible cards are, still, 52, so, the probability will be

$p = \frac{12}{52}$

$p = \frac{3}{13}$

We know that the card drawn must be a face card, o not being a face card. There is no third choice here. So, the probability of drawing a face card OR not drawing a face car its:

$p = \frac{52}{52} = 1$

$p(the \ card \ is \ a \ face \ card) + p(the \ card \ is \ not \ a \ face \ card) = 1$

$p(the \ card \ is \ not \ a \ face \ card) = 1 - p(the \ card \ is \ a \ face \ card)$

but, we know that

$p(the \ card \ is \ a \ face \ card = \frac{3}{13}$

$p(the \ card \ is \ not \ a \ face \ card) = 1 - \frac{3}{13}$

$p(the \ card \ is \ not \ a \ face \ card) = \frac{10}{13}$

What is 12.5% of 150

Anit [1.1K]

One hack is recognizing that
x% of 100 is x
150 is 1.5 times of 100 so
x% of 150=1.5x
therfor
12.5% of 150=1.5*12.5=18.75

anyway

percent means parts out of 100
12.5%=12.5/100=0.125

'of' means multiply
12.5% of 125=0.125*150=18.75

the answer is 18.75
