15 people working 5 hours per day can make 30 units of a product in 10 days. Assuming all other factors remaining constant and people of same efficiency are used to make the same products, in how many days can 10 people
make 10 units of the product if each of them works 10 hours per day?
SELECT ONLY ONE
2.5 days
7.5 days
12 days
26 days

2.5 days

Step-by-step explanation:

(15 people(5 hr/day)(10 day)) / 30 units = 25 hr/unit

10 units would require 250 hr of labor.

250hr / (10people(10 hr/day) = 2.5 days

the answer is (-4,-4)

hope this ! : d

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
