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]

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.

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 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

Gary goes to the grocery store to buy hot dogs and hamburgers for a cookout. He buys a total of 8 packages for a total of $28.52. A package of hot dogs costs $2.29 and a package of hamburgers costs $5.69.

Answers

Answer:

3 hamburger packs

5 hot dog packs

Step-by-step explanation:

The system of equations that corresponds to the situation is:

1. x + y = 8

2. 2.29x + 5.69y = 28.52

Let's use variables to represent the unknowns in the problem.

Let:

x = number of packages of hot dogs purchased

y = number of packages of hamburgers purchased

We are given the following information:

1. Gary buys a total of 8 packages: x + y = 8

2. The total cost of the packages is $28.52: 2.29x + 5.69y = 28.52

So, the system of equations that corresponds to the situation is:

1. x + y = 8

2. 2.29x + 5.69y = 28.52
