Answer:

D

Step-by-step explanation:

Standard equation of the circle is at the origin x^{2} +y^{2} = r^{2} But this is only when the center of the circle is at (0,0). In the quesiton stated the center is (-1/2, √57) .

When the center isn't (0,0) the equation is (x-h)^{2} +(y-k)^{2} =r^{2} (h,k) is center and r is radius.

So inputting the center (-1/2, √57) and radius = in the equation:

(x- -\frac{1}{2} )^{2} + (y-\sqrt{57} )^{2} = 9^{2}

(x+\frac{1}{2})^{2}  + (y-\sqrt{57} )^{2} = 81

Alex Ar [27]

Answer: 29 = 5/6

Step-by-step explanation:

first you would convert 1 2/3 into a improper faction. So you would multiply 1 and 3  then add 2 so 5/3 then multiply that by 1/2. You would multiply the numerators and denominators, so 5 times 1 and 3 times 2 which gives you 5/6.

Can someone help me with this?
Roman55 [17]

Answer:

Step-by-step explanation:

We first need to figure out how much money Jackie has since Pilar has the same amount of money, but in different coins. Jackie has 24 dimes and 13 quarters, so the amount of money is $2.40 + $3.25 = $5.65; therefore, Pilar has $5.65 also. In order to determine how many nickels and quarters Pilar has, we have to have a system of equations. It's up to us to write the equations we need to solve this. The first equation has to do with the NUMBER of coins Pilar has, the second has to do with the VALUE of each coin. We know that Pilar has only nickels and quarters and that she has a total of 53 coins. So the NUMBER equation is

n + q = 53

The VALUE equation relates how much each coin is worth to the total amount of money it equals:

.05n + .25q = 5.65.

Go back to the first equation and solve it for either n or q. I solved it for n:

n = 53 - q

Plug this into the second equation in place of n now to get:

.05(53 - q) + .25q = 5.65 and

2.65- .05q + .25q = 5.65 and

.20q = 3 so

q = 15. This means that there are 15 quarters. If there are 15 quarters, then there are

n + 15 = 53 nickels and

n = 38 nickels.

I need help with this but take your time it is early!
IgorC [24]

Answer:

Each part is 3.5 inches long.

Step-by-step explanation:

The ruler has a length of 7-inches, so when you want to split it directly in half, you divide 7/2. This is the number 3.5 inches. On the ruler you can see when looking at the first segment that it goes from 0 inches to half-way between 3 inches and 4 inches, which is 3.5 inches.
