The circle has its center at (h, k) = (2, 0), and has a radius of r = 4. The standard form equation is ...

(x -h)² +(y -k)² = r²

For the given values of (h, k) and r, this equation is ...

A woodworking artist makes two types of carvings: type X and type Y. He

ivolga24 [154]

Answer:

part C. 3x + 2y < 30, 5x + 7y < 105

Step-by-step explanation:

Part 1:

spends 3 hours making each type X (3x)-each type x will take 3 hours so as the number of type x increases, the hours will increase by 3.

spends 2 hours making each type Y (2y)-each type y will take 2 hours so as the number of type y increases, the hours will increase by 2.

Part 2:

he can spend up to 30 hours each week making carvings. (<30)-because he cannot spend more than 30 hours

Therefore, He has to spend 30 hours or less to make type X and type Y.

3x + 2y < 30

Part 3:

His materials cost him $5 for each type X carving. (5x)-each type x will take $5 so as the number of type x increases, the cost will increase by 5.

His materials cost him $7 for each type Y carving, (7y)-each type y will take $7 so as the number of type y increases, the cost will increase by 7.

Part 4:

he must keep his weekly cost for materials to $105 or less (<105)-total cost cannot be more than $105.

Therefore, the total cost of making x and y should be $105 or less.

5x + 7y < 105

$\text{The hundredths place is the 2nd place after the decimal}\\\\\text{The number in the hundredths place in this case is 9}\\\\\text{You would round up if the number to the right of it it's 5 or greater}\\\\\text{You would keep it the same if the number to the right of it is 4 or less}\\\\\text{The number to the right of 9 is 5, so round up}\\\\\text{When you round, it would turn into: 12.90, since the 9 turns into a "10",}\\\text{then you carry the one over to the next number}\\\\$
