Linda is 3 1/years younger than Rose. Joahn is 8 1/3years older than Linda. To the nearest year, what is the difference in Rose's age and Joahn's age?

Answers

Answer: 5 years

Step-by-step explanation:

Given

Linda is [tex]3\ \frac{1}{3}\ yr[/tex] younger than Rose

Johan is [tex]8\ \frac{1}{3}\ yr[/tex] older than Linda

Suppose the age of Rose is [tex]x[/tex]

So, Linda's age

[tex]x-\dfrac{3\times3+1}{3}=x-\dfrac{10}{3}[/tex]

Johan's age

[tex]x-\dfrac{10}{3}+\dfrac{8\times3+1}{3}=x+\dfrac{-10+25}{3}\\\\x+\dfrac{15}{3}=x+5[/tex]

Difference between the Rose's and Johan's age is

[tex]\Rightarrow x+5-x=5\ yr[/tex]

Tim has read ​30 % of a book. He has 56 more pages to finish. How many pages are there in the​ book?

Answers

Answer:

80 pages

Step-by-step explanation:

Let the number of pages is xTim has read ​30 % of a book

Remaining

100% - 30% = 70%

70% of x is 0.7x

0.7x = 56x = 56/0.7x = 80 pages

Answer:

[tex] \bf \huge 80 \: pages[/tex]

Step-by-step explanation:

Given that :

Tim has read 30 % of a book.He has 56 more pages to finish.

to find :

How many pages are there in the book ?

let us assume :

total pages of book is 100•/•

explanation :

⟼ total book = 100•/•

⟼ Tim has read 30 % of a book.

⟼ 100 - 30 •/• = 70 •/•

⟼ 70 •/• = 56 pages

⟼ 1 •/• = 56 / 70

⟼ 100 •/• = 56 / 70 × 100

⟼ 100 •/• = 56 / 7 × 10

⟼ 100 •/• = 8 × 10

⟼ 100 •/• = 80 pages

tim has 80 total pages in book.

A chemist has three different acid solutions. The first acid solution contains 20 % acid, the second contains 40 % and the third contains 70 % . They want to use all three solutions to obtain a mixture of 56 liters containing 50 % acid, using 2 times as much of the 70 % solution as the 40 % solution. How many liters of each solution should be used?

Answers

Answer:

The volume of the first acid solution (containing 20% acid) in the mixture is 14 liters

The volume of the second acid solution (containing 40% acid) in the mixture is 14 liters

The volume of the third acid solution (containing 70% acid) in the mixture is 28 liters

Step-by-step explanation:

The percentage of acid in the first acid solution = 20%

The percentage of acid in the second acid solution = 40%

The percentage of acid in the third acid solution = 70%

The volume they want to use the three solutions to obtain a mixture of = 56 liters

The concentration of the mixture they want to obtain = 50%

The amount of the 70% solution to be used = 2 × The volume of the 40% solution to be included

Let 'x', 'y', and 'z', represent the volumes of the first second and third acid solutions in the mixture

Therefore, from the question parameters, we get;

x + y + z = 56...(1)

z = 2·y...(2)

0.2·x + 0.4·y + 0.7·z = 0.5 × 56...(3)

Multiplying equation (3) by 10 and then subtracting equation (1) multiplied by 2 from the result gives;

10 × (0.2·x + 0.4·y + 0.7·z = 0.5 × 56) = 2·x + 4·y + 7·z = 5 × 56 = 280

2·x - 2·x + 4·y - 2·y + 7·z - 2·y = 280 - 2 × 56 = 168

2·y + 5·z = 168

From equation (2) and (4), we get;

2·y + 5·z = 2·y + 5×(2·y) = 168

12·y = 168

y = 168/12 = 14

The volume of the second acid solution in the mixture, y = 14 liters

From equation (2), we have;

z = 2·y

∴ z = 2 × 14 = 28

The volume of the third acid solution in the mixture, z = 28 liters

From equation (1), we get;

x + y + z = 56

x = 56 - (y + z)

∴ x = 56 - (14 + 28) = 14

The volume of the first acid solution in the mixture, x = 14 liters.

A variety pack of snacks contains 4 pretzel bags, 3 popcorn bags and 3 cheddar cracker bags. What is the probability that someone selects a pretzel bag, keeps it, and then selects another pretzel bag. HELLP PLS

Answers

Answer:

2/15

Step-by-step explanation:

Given that :

pretzel = 4

Popcorn = 3

Cheddar cracker = 3

Total = 4 + 3 + 3 = 10

Probability = Required outcome / Total possible outcomes

Selecting with replacement :

First selection :

P(pretzel bag) = 4 / 10

Second selection :

P(pretzel bag) = 3 / 9

P(2 pretzel bags) = 4/10 * 3/9 = 12 / 90 = 2/15

What is the volume of a hemisphere with a radius of 4.9 ft, rounded to the nearest
tenth of a cubic foot?

Answers

The volume of the hemisphere with the given value of radius to the nearest tenth is 246.4 cubic foot.

Hemisphere

A hemisphere is gotten when a sphere is cut into two equal halves.

The volume of a hemisphere is expressed as;

V = (2/3)πr³

Where r is the radius and π is pi ( π = 3.14 )

Given the data in the question;

Radius of the hemisphere r = 4.9ftVolume of the hemisphere V = ?

To determine the volume of the hemisphere, we substitute our values into the expression above.

V = (2/3)πr³

V = (2/3) × π × (4.9ft)³

V = (2/3) × π × 117.649ft³

V = 246.4ft³

Therefore, the volume of the hemisphere with the given value of radius to the nearest tenth is 246.4 cubic foot.
