A Runner ran 1 4/5 miles on Monday and 6 3/10 on Tuesday. How many times her Monday’s distance was her tuesdays distance?

Can anyone help me with this please?

Answers

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

3 1/2 or 3.5

Step-by-step explanation:

We have to divide to see how many times her monday's distance was her tuesdays distance.

$6\frac{3}{10}\div \:1\frac{4}{5}$

$=\frac{63}{10}\div \frac{9}{5}$

$\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{b}\div \frac{c}{d}=\frac{a}{b}\times \frac{d}{c}$

$=\frac{63}{10}\times \frac{5}{9}$

$\mathrm{Multiply\:fractions}:\quad \frac{a}{b}\times \frac{c}{d}=\frac{a\:\times \:c}{b\:\times \:d}$

$=\frac{63\times \:5}{10\times \:9}$

$=\frac{315}{10\times \:9}$

$=\frac{315}{90}$

$\mathrm{Cancel\:the\:common\:factor:}\:45$

$=\frac{7}{2}$

$=3\frac{1}{2}$

we can also be 3.5 in decimal form

If this helps you have to use the formula (x1,y1) and (x2,y2). So for number 1 it would be 7x - 3x and 2y - 4y

$1.7x \times 2x - 4y \times 3x \\ 7x \times 3x - 4y \times 2y \\ 21x ^{2} - {8}y^{2} \\ 2.3x \times 2x - 4y \times 3y \\ 6x ^{2} - {12y}^{2} \\ 3.4x \times 5x - 5x \times 4x \\ {20x}^{2} - {20x }^{2} \\ 0 $

Solve the equation r = 1/(x-1) for x in terms of r. In other words, manipulate the equation until you have x equal to an expression with r's in it but no x's.

Answers

Answer:

$x=\frac{1}{r} +1$

Step-by-step explanation:

$r=\frac{1}{x-1}$
$r(x-1)=1$
$x-1=\frac{1}{r}$
$x=\frac{1}{r} +1$

Answer:

$x=\dfrac{1+r}{r}$

Step-by-step explanation:

Given equation:

$r=\dfrac{1}{(x-1)}$

Multiply both sides by (x - 1):

$\implies r(x-1)=\dfrac{1}{(x-1)} \cdot (x-1)$

$\implies r(x-1)=1$

Expand the brackets:

$\implies rx-r=1$

Add r to both sides:

$\implies rx-r+r=1+r$

$\implies rx=1+r$

Divide both sides by r:

$\implies \dfrac{rx}{r}=\dfrac{1+r}{r}$

$\implies x=\dfrac{1+r}{r}$

What type of graph is best to use to show changes over time? A. bar graph B. line graph C. histogram D. circle graph
(will give brainliest if correct)

Answers

Answer: B

The best type of graph to show changes over time is a line graph. A line graph is ideal for displaying trends and variations in data over a continuous period. It consists of a series of data points connected by line segments, allowing for a clear visualization of how values change over time. Bar graphs, histograms, and circle graphs are better suited for other types of data analysis, such as comparing categories or showing proportions.

Step-by-step explanation: Hope this helps! :)

Your answer is B, line charts and graphs are best.

A bookstore sells 7 books for $59.50. Which table represents the relationship between number of books and the total price?

Answers

Answer:

The answer is A

Step-by-step explanation:

The answer is A because if you divide 59.50/7 you would get 8.50, and 8.50 x 8 is 68! You can easily eliminate any other answer choices if the distance between the values is not equal!

Answer:

A is the correct answer.

Step-by-step explanation:

If you divide $59.50 by 7 you get 8.5. Which would be $8.50. You can then go through each table and multiply the cost of one book with how many books are being bought. So yeah. Hope this helps

Three research departments have 8 ,10 , and 7 members, respectively. Each department is to select a delegate and an alternate to represent the department at a conference. In how many ways can this be done?

Answers

We can conclude that exists 211680 ways.

How many ways can this be done?

We know that the three research department is have 8, 10, and 7 members.

We choose a delegate and an alternate to represent the department.

First case: department have 8 members.

So, for a delegate, we have 8 options, and for a alternate 7, so a total of

$8 \times 7 = 56 \ \text{options}$

Second case: department have 10 members.

So, for a delegate, we have 10 options, and for a alternate 9, so a total of

$10\times 9 =90 \ \text{options}$

Third case: department have 7 members.

So, for a delegate, we have 7 options, and for a alternate 6, so a total of

$7\times6 = 42 \ \text{options}$

Therefore, we get:

$56 \times 90 \times 42 = \bold{211680}$

Hence, we conclude that exists 211680 ways.

For a similar problem about this, please click the link below:

https://brainly.com/question/30958797

To determine the number of ways to select a delegate and an alternate from each department, we can multiply the number of choices for each department together.

For the first department with 8 members, there are 8 choices for selecting a delegate. After choosing a delegate, there remain 7 members, so there are 7 choices for selecting an alternate. Therefore, there are 8 × 7 = 56 ways to select a delegate and an alternate from the first department.

Similarly, for the second department with 10 members, there are 10 choices for selecting a delegate and 9 choices for selecting an alternate. Hence, there are 10 × 9 = 90 ways to select a delegate and an alternate from the second department.

For the third department with 7 members, there are 7 choices for selecting a delegate and 6 choices for selecting an alternate. Thus, there are 7 × 6 = 42 ways to select a delegate and an alternate from the third department.

To find the total number of ways to select delegates and alternates from all three departments, we multiply the number of choices for each department together:
56 × 90 × 42 = 211,680.

Therefore, there are 211,680 ways to select a delegate and an alternate from each department.

Answer:

first row last column, second row first column, third row third column, last row second column

Step-by-step explanation:

first row last column: doing division w/ exponents means you have to subtract the exponents. 9-3=6 and since they have the same base, you don't have to do anything with it, so the answer is the last column.

second row first column: properties show that the square of -5/6 is equal to -5^2/6^2 or 5^2/-6^2. therefore, the answer is the first column.

third row third column: anything to the power of one is itself.

last row second column: anything to the power of zero is one.

1) Each lunch for a school field trip has a turkey, roast beef, or bologna sandwich, an orange or apple for a fruit, and a cookie or muffin for dessert. Amanda and Zack would like to…

-know the number of possible lunch options.

-P of having any meal with NO COOKIE.

(use sample space, tree diagram, and counting principle)

Answers

1) there are 12 possible lunch options. 2) the probability of having any meal with no cookie is 1/2 or 0.5.

How to find the number of possible lunch options.

1) Number of possible lunch options:

To determine the number of possible lunch options, we need to consider the choices for each component of the lunch.

- Sandwich: There are 3 options (turkey, roast beef, or bologna).

- Fruit: There are 2 options (orange or apple).

- Dessert: There are 2 options (cookie or muffin).

Using the counting principle, we multiply the number of options for each component together:

Number of possible lunch options = 3 (sandwich options) × 2 (fruit options) × 2 (dessert options) = 12.

Therefore, there are 12 possible lunch options.

2) Let's examine the favorable outcomes for each component:

- Sandwich: There are still 3 options (turkey, roast beef, or bologna).

- Fruit: There are 2 options (orange or apple).

- Dessert: There is 1 option (muffin, as we want to exclude cookies).

Using the counting principle, we multiply the number of options for each component together:

Number of favorable outcomes (no cookie) = 3 (sandwich options) × 2 (fruit options) × 1 (muffin option) = 6.

The total number of possible outcomes is still 12 (as calculated in the previous step).

Therefore, the probability of having any meal with no cookie is:

P(No cookie) = Number of favorable outcomes / Total number of possible outcomes = 6 / 12 = 1/2 or 0.5.

Hence, the probability of having any meal with no cookie is 1/2 or 0.5.

You will choose to write either a narrative essay or an informational response paragraph.The Railway ChildrenBy Edith NesbitChapter I, The Beginning of ThingsThey were not railway children to begin with. I don't suppose they had ever thought about railways except as a means of getting to Maskelyne and Cook's, the Pantomime, Zoological Gardens, and Madame Tussaud's. They were just ordinary suburban children, and they lived with their Father and Mother in an ordinary red-brick-fronted villa, with coloured glass in the front door, a tiled passage that was called a hall, a bath-room with hot and cold water, electric bells, French windows, and a good deal of white paint, and 'every modern convenience', as the house-agents say.There were three of them. Roberta was the eldest. Of course, Mothers never have favourites, but if their Mother HAD had a favourite, it might have been Roberta. Next came Peter, who wished to be an Engineer when he grew up; and the youngest was Phyllis, who meant extremely well.Mother did not spend all her time in paying dull calls to dull ladies, and sitting dully at home waiting for dull ladies to pay calls to her. She was almost always there, ready to play with the children, and read to them, and help them to do their home-lessons. Besides this she used to write stories for them while they were at school, and read them aloud after tea, and she always made up funny pieces of poetry for their birthdays and for other great occasions, such as the christening of the new kittens, or the refurnishing of the doll's house, or the time when they were getting over the mumps.These three lucky children always had everything they needed: pretty clothes, good fires, a lovely nursery with heaps of toys, and a Mother Goose wall-paper. They had a kind and merry nursemaid, and a dog who was called James, and who was their very own. They also had a Father who was just perfectnever cross, never unjust, and always ready for a gameat least, if at any time he was NOT ready, he always had an excellent reason for it, and explained the reason to the children so interestingly and funnily that they felt sure he couldn't help himself.You will think that they ought to have been very happy.
