Terry is making meatballs for a family dinner. He needs ground turkey and ground beef to make the meatballs.

Ground turkey costs $4.50 per pound. Terry buys 2.6 pounds of ground turkey.

1. What is the total cost, in dollars, for 2.6 pounds of ground turkey? Show or explain how you got your answer.

Answers

It will be $11.70 for 2.6 pounds and to find the answer is to multiply $4.50 x 2.6 and you get $11.70

1 pound=$4.50
⬇️/2
0.5 pounds=$2.25
⬇️/5
0.1 pounds=$0.45

4.5+4.5+2.25+0.45=11.7=2.6 pounds
Answer=$11.70

Chucky spent $23.24 on supplies to make cookies for his booth at the show. He made a profit of $24.76. Each cookie was $1, how many cookies did he sell?
c - 23.24 = 24.76
c + 23.24 = 24.76
c - 24.76 = 23.24
c + 24.76 = 23.24

Chucky spent $23.24 on supplies to make cookies for his booth at the show. He made a profit of $24.76. Each cookie was $1, how many cookies did he sell?
5 cookies
1.5 cookies
50 cookies
48 cookies

Answers

Answer:

just do this 24.76min. 23.24 then see what u have got for

Answer:

c - 23.24 = 24.76 (the first option)

48 cookies

Explanation:

Profit is equal to revenue(amount made) minus costs, or r - cost = p. The revenue is 1*cookies sold, or c. So, c - 23.24 = 24.76.

Solving is relatively simple,

c - 23.24 = 24.76

c = 48 (add 23.34 to both sides)

Step-by-step explanation:

Please mark brainliest...

multiply each value of the C. by 1,000 to get the # of C.s divide the # of C.s / T.s this gives you C.s per T.Convert to ratio formatthere is on average 15 to 20 C.s per T.5250/273 = 14.0756250/325 = 19.2307250/377 = 19.2309250/273 = 19.230 6250 = y

377 572

2. multiply both sides by 572

3. 572 . 6250 = y

377

4. divide known pair

572 x 19.230 = y

5. solve for y

These are linear equations, so there is x and y. On number one the first thing they plotted was (3,8) so in a function table the 3 would be on the left side and the 8 would be on the right side. I’ll leave you with the rule of the first one, if the rule is times 2 plus to the how would you put it in a function table.

The first thing that you would put into the function table on the first question would be as I said earlier 3 and then 8. The rule is the rate. Using a function table will be very helpful (That’s why I keep mentioning one). Let me know if this helps.

Both effectively changed the popular opinion about emotional issues for their countries and brought in a wave of change that was long overdue. But the practice of non-violent protest, or civil disobedience, started long before either Gandhi or King. It began with a quiet, shy poet who is best known for writing a lot about a pond.Henry David Thoreau lived from 1817 until 1862, mainly in the area of Concord, Massachusetts. The issue that would tear the country apart in the 1860s had already begun dividing the nation. Thoreau was only 14 when Nat Turner led the slave rebellion in Virginia and was later hanged. In his late 20s, Thoreau began speaking against slavery in public, echoing the voices of freedmen like Frederick Douglass and Lewis Hayden.Thoreau believed that a government that supported slavery was corrupt and immoral. He was also deeply suspicious of government. For these and other reasons, Thoreau refused to pay his poll tax for a number of years. The poll tax was a legal tax owed by every person. It was basically a tax on one's body. After not paying for years, he was at last arrested. He spent only one night in jail, however, as a relative paid the tax for him. He was reportedly furious that any tax was paid on his behalf.It was this experience that Thoreau wrote about in an essay called "Civil Disobedience." In this essay, he argued that being moral and just came before allegiance to government. He wrote If the machine of government is of such a nature that it requires you to be the agent of injustice to another, then, I say, break the law." He also felt that voting was not enough to ensure that the right thing be done. He wrote that "even voting for the right is doing nothing for it A wise man will not leave the right to the mercy of chance" He felt that one had a moral responsibility to resist unjust laws.Which line from Part 1 best explains Thoreau's message?
