Answer:
9π
Step-by-step explanation:
What we need to do here is convert this equation into a standard circle equation;
x^2+y^2 + 3 = -4y + 6x-1,
x^2+y^2+4y-6x+1 = 0,
x^2-6x+(-3)^2 + y^2+4y+(2)^2 = 3^2
(x-3)^2 + (y+2)^2 = 3^2,
so we have a circle with a radius of 3, and hence the area of our region is π(3)^2 = 9π. correct!

____ cans of white paint per can of black paint
Answer:
2 cans
Step-by-step explanation:
just divide y by x and you would get 2.
Megan and Desmond each added the same amount of water to their aquariums. Megan mixed 5 mL of a chemical solution with every gallon of water for her aquarium. Desmond mixed 8 mL of the chemical solution with every 2 gallons of water for his aquarium.
Which of these statements is true?
Answer:
i think it is the second one
Step-by-step explanation:
The statement "Megan added more chemical solution to her aquarium than Desmond did" is true.
What is Unit of Measurement?A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity.
To compare the amount of chemical solution used by Megan and Desmond, we need to convert their rates to a common unit.
Let's convert Megan's rate to mL per 2 gallons by using proportions:
5 mL / 1 gallon = x mL / 2 gallons
Multiplying both sides by 2, we get:
10 mL = x
So Megan added 10 mL of chemical solution per 2 gallons of water.
Desmond's rate is already given as 8 mL per 2 gallons of water, so we can compare their rates directly.
Since 10 mL is greater than 8 mL, Megan added more chemical solution to her aquarium than Desmond did.
Therefore, the statement "Megan added more chemical solution to her aquarium than Desmond did" is true.

Which of the following is the graph of the inverse of f(x)=2x-3
Answer:
(-3,0) (0,1.5
Step-by-step explanation:
The answer choice which is the graph of the inverse of f(x)=2x-3 is; the graph of; f(x) = x/2 + 1.5.
What is the graph of the inverse of f(x)=2x-3?It follows from the task content that the function given is; f(x)=2x-3.
Hence, to find the inverse function;
y = 2x - 3x = y/2 + 1.5.Interchange the variables;
y = x/2 + 1.5.On this note, it follows that the inverse function is;
f(x) = x/2 + 1.5The graph of the inverse function therefore has points; (0, 1.5) and (2, 2.5) as points on the graph.

Number 2: (look at pivture) 10 point
Answer:
A
Step-by-step explanation:
Because the arrow is going 2 in the right direction...so you have to have the 2 in the equation...
and the reason it equals 5 instead of a (-) number is because of the KCC rule
so basically the equation is 2+3
or if you don't want the long way just look at all of the equations...only one of the have a 2 in it so it is automatically the correct answer
Answer:
I think it should be A.
Step-by-step explanation:
The first arrow represents 2, and the second arrow represents subtracting -3 from it, represented as -(-3). This means that the first part of the equation is 2 - (-3). Now you have to solve it. When subtraction is modeled like this with a negative number, it actually means addition. This means that the answer should be as simple as 2+3 because there were two negative signs. 2+3=5, so A should be the answer.

Which Quaker belief do you think influenced William Penn’s attitude toward Native Americans? Explain your answer.
Your answer should be at least 5-7 sentences in length.
Giving brainliest pls this is all my points!
Answer:
Penn and other Quakers believed that everyone had to seek God in his or her own way. Penn also thought that religious tolerance – or “liberty of conscience” – would create stronger governments and wealthier societies. Other English thinkers in the 1600s shared these ideas. But Penn had the opportunity to act on his beliefs. In Pennsylvania, religious tolerance was the law.
Penn welcomed settlers from all faiths to Pennsylvania. Each of the other American colonies had established an official church, but Penn did not. He sought out religious groups suffering in Europe, and invited them to his colony. He even gave some groups land. Yet religious tolerance did not mean that colonists of all faiths had equal rights. Only Christians could vote or hold political office. But all settlers could take part in the social and economic life of Pennsylvania.
Penn’s belief that “Religion and Policy…are two distinct things, have two different ends, and may be fully prosecuted without respect on to the other” took hold and became one of America’s most important ideals.

Dan charges a fixed amount per hour. He charges £180 for a job which takes 12 hours. Work how much he will charges for a job which will take 18 hours.
Answer:
270 pounds
Step-by-step explanation:
half of 12 is 6, so 18. Then you take half of 180 and add to 180
Answer:
18 hours = £270
Step-by-step explanation:
Find how much he charges per hour. Divide:
[tex]\frac{180}{12}=15[/tex]
So ha charges about 15 an hour. Multiply this price by the number of hours:
[tex]15*18=270[/tex]
Therefore, he will charge £270 for a job that takes 18 hours.
OR
Set a proportional relationship since he charges a fixed amount:
[tex]\frac{price}{time}=\frac{price}{time}[/tex]
Insert the appropriate corresponding values:
[tex]\frac{180}{12} =\frac{x}{18}[/tex]
Solve for the price after 18 hours of work, represented by x. Cross multiply:
[tex]12(x)=180(18)\\\\12x=3240[/tex]
Solve for x. Use inverse operations to isolate the variable. Divide both sides by 12:
[tex]\frac{12x}{12} =\frac{3240}{12} \\\\x=270[/tex]
Therefore, after 18 hours, he will charge £270.

1) B is the answer
2) C is the answer
Step-by-step explanation:
1) 21:40=0.525
2) 21:40=0.525=52.5%
Because with percents it has to be out of 100 so 0.525 is not out of a hundred so multiply 0.525 times 100 to get 53.5%.
