if a bag has 22 orange, 18 red, 12 green and 8 blue marbles what is the probability, that I draw blue marble, keep it, then draw another blue marble?

Answers

Answer 1

Answer:

14/885 or 1.58%

Step-by-step explanation:

In total, there are 60 marbles. The probability of drawing a blue marble the first time is 8/60. If you keep the one blue marble that was drawn, the total number of marbles in the bag is 59, and there are now 7 blue marbles. The probability of drawing a blue marble now is 7/59.

In order to find out the total probability of drawing two blue marbles in a row, you need to multiply these two fractions.

(8/60) x (7/59) = 56/3540 = 14/885 (approx. 1.58%)

If ABCD is a rectangle, BD = 2x + 5 and AC = 7x - 40. Find the value of BE.

Answers

Answer:

AC = 23

BD = 23

Step-by-step explanation:

ABCD is a rectangle,

AC and BD are its diagonals.

Diagonals of a rectangle are congruent.

Therefore,

AC = BD

7x - 40 = 2x + 5

7x - 2x = 5 + 40

5x = 45

x = 45/5

x = 9

BD = 2x + 5 = 2*9 + 5 = 18 + 5 = 23

AC = 7x - 40 = 7*9 - 40 = 63 - 40 = 23

Tyrone had $17,000 to invest. He invested part of that amount at 2.5% annual interest for one year and the other part at 6.5% annual interest for one year. The amount of interest earned for both investments was $550. Let x represent the amount of money invested in the first account and y represent the amount of money invested in the second account. Which system of equations best represents the situation?

Answers

Answer:

The system of equations best represents the situation

x + y = 17,000.... Equation 1

0.025x + 0.065y = 550... Equation 2

Step-by-step explanation:

Let

x represent the amount of money invested in the first account and

y represent the amount of money invested in the second account.

We are told that:

Tyrone had $17,000 to invest.

Hence,

x + y = $17,000

x + y = 17,000..... Equation 1

We also known that:

He invested part of that amount at 2.5% annual interest for one year and the other part at 6.5% annual interest for one year. The amount of interest earned for both investments was $550

The formula for Interest =

Principal(Amount invested) × Rate × Time.

Hence:

25% × x + 6.5% × y = 550

0.025x + 0.065y = 550... Equation 2

The system of equations best represents the situation

x + y = 17,000.... Equation 1

0.025x + 0.065y = 550... Equation 2

JJill begins the summer with $500 in her savings account. Each week, she withdraws $20. Her brother, Sam,starts the summer with $150 in his account. He adds $30 to his account each week. At what week will both Jill and Sam have the same amount in their account.

Answers

Answer:

7th week

Step-by-step explanation:

Let us represent the number of weeks as x

Jill begins the summer with $500 in her savings account. Each week, she withdraws $20.

$500 - $20× x

500 - 20x

Her brother, Sam,starts the summer with $150 in his account. He adds $30 to his account each week.

$150 + $30 × x

150 + 30x

At what week will both Jill and Sam have the same amount in their account?

We solve this be Equating both Equations together

Jill = Sam

500 - 20x = 150 + 30x

Collect like terms

500 - 150 = 30x + 20x

350 = 50x

Divide both sides by 50

50x/50 = 350/50

x = 7 weeks

Therefore, at the 7 week, Jill and sam would have the same amount in their accounts

Wang Hao wants to spend at most \$15$15dollar sign, 15 on dairy products. Each liter of goat milk costs \$2.40$2.40dollar sign, 2, point, 40, and each liter of cow's milk costs \$1.20$1.20dollar sign, 1, point, 20.

Answers

Answer:

2.40G + 1.20C ≤15

Step-by-step explanation:

The inequality function is

Given that

The cost of goat milk for each liter is $2.40 = G

And, the cost of the cow milk for each liter is $1.20 = C

Now the equation would be

2.40g + 1.20c

Now this must be lower or equal than $15

So, the inequality function would be

2.40G + 1.20C ≤15

hence, the inequality function is 2.40G + 1.20C ≤15

Answer:

2.4G + 1.2C < or = to 15

Step-by-step explanation:

We are given that each liter of goat milk costs $2.40$2.40dollar sign, 2, point, 40, and each liter of cow's milk costs $1.20$1.20dollar sign, 1, point, 20.How can we express the total cost of liters of goat milk and cow's milk that Wang Hao can buy?Hint #22 / 3The cost of GGG liters of goat milk is 2.4G2.4G2, point, 4, G, and the cost of CCC liters of cow's milk is 1.2C1.2C1, point, 2, C. Therefore, the total cost of liters of goat milk and cow's milk that Wang Hao can buy is 2.4G+1.2C2.4G+1.2C2, point, 4, G, plus, 1, point, 2, C.We are also given that Wang Hao wants to spend at most $15$15dollar sign, 15 on dairy products. This means that it is possible for Wang Hao to spend $15$15dollar sign, 15 or any amount less than this. Let's use this condition to create the appropriate inequality.Hint #33 / 3The following inequality represents the number of liters of goat milk and cow's milk Wang Hao can buy on his budget: 2.4G+1.2C≤152.4G+1.2C≤15

when the least common multiple of two positive integers is divided by their greatest common divisor, the result is 33. if one integer is 45, what is the smallest possible value of the other integer?

Answers

The smallest value of the other number will be 3 ×5× 11 =165

In the given statement is :

When the least common multiple of two positive integers is divided by their greatest common divisor, the result is 33. If one integer is 45.

To find what is the smallest possible value of the other integer

Now, According to the question

m∠AOC = 15°m∠BOC = 15°

Step-by-step explanation:

Given the angle ∠AOB

It is stated that CO is the angle bisector of ∠AOB.

Given that ∠AOB = 30°

As we know that the angle bisector bisects the angle into two equal angles.

Thus, the angle bisector CO bisects the angle ∠AOB into two equal angles, which are:

m∠AOCm∠BOC

as

∠AOB = 30°

Thus, the two formed angles i.e m∠AOC and m∠BOC by the angle bisector would be half of the angle bisector as the angle bisector bisects the angle ∠AOB into two equal angles.

Therefore,

m∠AOC = 15°m∠BOC = 15°

I GIVE BRAINLILSET \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\ There is only 1 question and its worth a lot of points so plz answer it The large subcontinent that is india is borded by a great ancient cilization or Harappan civilization. It is named after Harappa, one of its two important cities, that developed in the Indus river valley. Like other earlycivilizations, the river was used for theirrigation of crops. As farming increased, the population increased, and by about 3,000 B.C.E. neolithic villages were developing into larger cities. The other major city of the Indus Valley was Mohenjo-Daro. Both were large, around three miles in circumference, and had populations of around 40,000. Each had huge hilltop structures called a citadel. Unlike Mesopotamia or Egypt, it is impossible to learn much about the Harappan society for two reasons. First, archeologists cannot get to the earliest Harappan physical remains. Silt deposits buried the lndus valley so high that the level of the land as well as the water table was raised. Thus, the earliest Harappan remains lie below the water table. The earliest remains that archeologists can study begin at about 2500 B.C.E., when the Harappan society was fully developed.Second, historians cannot decipher Harappan writings. There is no Rosetta Stone for the Harappan written language. Although historians have thousands of clay seals, copper tablets, and other artifacts with Harappan script, they cannot read the ancient writings that allow them to learn details about their society.Cities were divided into lower dwellings and the higher level citadel, which housed important buildings. The large fortified citadels may indicate the existence of a theocratic and authoritarian society. The citadels were fortified with almost 40 foot walls, which may have served as protection for the cities populations in times of attack and as community centers in times of peace. The citadel in Mohenjo-Daro contains the earliest public water tank of the ancient world. The Great Bath measures 39 feet long and 22 feet wide. In the lower dwellings of Mohenjo-Daro, many people lived in one-room tenement structures. At the same time, there were individual houses of two the same time, there were individual houses of two a great ancient and three stories with over 20 - 30 rooms and numerous courtyards. Most of the larger houses had their own wells and built in brick ovens. Almost all of the houses had private bathrooms with showers and toilets that drained into the city sewage systems. The houses and sewage systems were just small features of Harappa and Mohenjo-Daros very well planned cities. Each city was laid out in a grid pattern, with rectangular blocks larger than modern city blocks. All houses were built of uniform oven- fired clay bricks. Houses had modern plumbing systems with baths, drains, and water chutes that led into sewers beneath the streets. The reason for this civilizations demise is unclear. We can only speculate a combination of a few factors such as: climate change left the valley dry with little water; over-planting may have left the cities hungry; and sickness and war may have left the cities too weak to survive. Until researchers are able to decipher Indus script, we may never know what actually occurred.____________________________________________________________________Question:1.Imagine a scenario where climate change destroys our civilization and write about its demise.
