find the length and width of a rectangle whose
Length is 5cm longer than it’s width
Whose area is 50cm

Answers

Answer 1

Step-by-step explanation:

width= x (let)

length= x+5

Area=50 cm

Now ,

area = l ×b

50 = (X×X+5)

50 = (2X + 5)

50÷ 2= X+5

25 -5 = X

X=20

LENGTH = X+5

20+5

=25

What is the probability of drawing four queens from a standard deck of cards, given that the first card drawn was a queen? Assume that the cards are not replaced.

3/20825
4/52
1/20825
3/52

Answers

The probability of drawing three queens from a standard deck of cards is 0.000162.

What is the probability?

Probability refers to a possibility that deals with the occurrence of random events.

The probability of all the events occurring need to be 1.

P(E) = Number of favorable outcomes / total number of outcomes

Total cards = 54

No. queens in a deck = 4

Probability of drawing a queen card = 4/54

Now that 1 queen has been taken, the no. of cards becomes = 53

and

no. of queens = 3

Probability of getting a queen again = (3/53)(4/54)

Two queens have already been removed.

No. of cards in the deck = 52

No. of queens in the deck = 2

Probability of drawing three queens

= (2/52)(3/53)(4/54)

= 0.000162 approximately

The probability of drawing three queens from a standard deck of cards is 0.000162.

The approximate solution to the given equation is x ≅ 148.4. The correct option is C. x ≈ 148.4

Solving equations

From the question, we are to determine the approximate solution to the given equation,

The given equation is

[tex]4lnx -8 =12[/tex]

First, add 8 to both sides

[tex]4lnx -8+8 =12+8[/tex]

[tex]4lnx =20[/tex]

In one country, approximately 144,000 of 900,00 residences are rentals. Determine the percentage of residences in the country that are rentals

Answers

The 62.5% of residences in the country that are rentals if the total number of residence in the country is 144,000.

What is the percentage?

It is defined as the ratio of two numbers expressed in the fraction of 100 parts. It is the measure to compare two data, the % sign is used to express the percentage.

We are assuming:

Total number of residence in the country = 144,000

In which 900,00 residences are rentals.

Percentage of residences in the country that are rentals:

= (90000/144000)×100

= 0.625×100

= 62.5%

Thus, the 62.5% of residences in the country that are rentals if the total number of residence in the country is 144,000.
