The ratio of ducks to ducklings at a park is 7:4. If there are 350 ducks, how many ducklings are there​

Answers

Answer:

200 duckings (350:200)

Solve this system of equations:
2x + 10y= 24
X = y-6

Answers

Answer:

(-3,3)

Step-by-step explanation:

Substitute x for the first equation

2(y-6) + 10y= 24

2y-12+10y=24

12y=36

y=3

Now solve for x by plugging in 3

x = 3-6

x=-3

Answer:

x = -3

y = 3

Step-by-step explanation:

2x + 10y = 24

x = y - 6

plugin x = y - 6 into the first equation

2(y - 6) + 10y = 24

solve for y

2y - 12 + 10y = 24

12y = 36

y = 3

plug y back into x = y - 6

x = 3 - 6

x = -3

Jason goes to the movies and purchases candy for $4.55. If he buys a total of 5 movie tickets and spends a total of $20.35, how much was each ticket?

Answers

3.16 per movie ticket

First you want to subtract the candy amount 4.55 from the total 20.35 that way we can get the total for the 5 tickets by themselves

20.35-4.55= 15.80

Then you want to divide the total for all five tickets by 5 which will get us the total for one ticket

15.80/5=3.16

A graph titled Monthly Sales and Advertising Costs has Advertising Costs (1,000 dollars) on the x-axis and sales (1,000 dollars) on the y-axis. A line goes through points (6.4, 117) and (6.6, 120). The slope of the trend line is 15. What does that mean in regard to the data of the scatterplot? Check all that apply. The slope represents the rate of change of the data. Advertising costs increase $15,000 as sales increase by $1,000. Sales increase $15,000 as ads increase by $1,000. A positive slope infers a negative correlation. A positive slope infers a positive correlation.

Answers

The data in the scatterplot on monthly sales and advertising costs, show that:

The slope represents the rate of change of the data. Sales increase $15,000 as ads increase by $1,000.A positive slope infers a positive correlation.

What can be inferred from the graph on Monthly sales?

In a linear model, the slope is used to depict the change in the value of y as a result of a change in x. If this slope is positive, then there is a positive relationship between the y and x values.

In this scenario, the slope is positive which shows that there is a positive relationship between sales and advertisements such that they both increase together.

Answers

Answer: $467.21

Step-by-step explanation:

8% of 600 = 48

600 - 48 = 552

8% of 552 = 44.16

552 - 44.16 = 507.84

8% of 507.84 = 40.6272

8% of 507.84 ≈ 40.63

507.84 - 40.63 = 467.21

Below is a speech made by Tecumseh to an American governor which will help provide insight as to why he joined the British side of the war.It is true I am a Shawnee. My forefathers were warriors. Their son is a warrior. From them I take only my existence; from my tribe I take nothing. I am the maker of my own fortune; and oh! that I could make of my own fortune; and oh! that I could make that of my red people, and of my country, as great as the conceptions of my mind, when I think of the Spirit that rules the universe. I would not then come to Governor Harrison to ask him to tear the treaty and to obliterate the landmark; but I would say to him: "Sir, you have liberty to return to your own country."The being within, communing with past ages, tells me that once, nor until lately, there was no white man on this continent; that it then all belonged to red men, children of the same parents, placed on it by the Great Spirit that made them, to keep it, to traverse it, to enjoy its productions, and to fill it with the same race, once a happy race, since made miserable by the white people, who are never contented but always encroaching. The way, and the only way, to check and to stop this evil, is for all the red men to unite in claiming a common and equal right in the land, as it was at first, and should be yet; for it never was divided, but belongs to all for the use of each. For no part has a right to sell, even to each other, much less to strangers -- hose who want all, and will not do with less.The white people have no right to take the land from the Indians, because they had it first; it is theirs. They may sell, but all must join. Any sale not made by all is not valid. The late sale is bad. It was made by a part only. Part do not know how to sell. All red men have equal rights to the unoccupied land. The right of occupancy is as good in one place as in another. There can not be two occupations in the same place. The first excludes all others. It is not so in hunting or traveling; for there the same ground will serve many, as they may follow each other all day; but the camp is stationary, and that is occupancy. It belongs to the first who sits down on his blanket or skins which he has thrown upon the ground; and till he leaves it no other has a right.1. why is Tecumseh upset?2. who made the Indians unhappy?3. Why does the land belong to the Indians? What differences do you notice in your body and attitude on the days that you move/exercise compared to the days that you don't?
