The number of widgets that a manufacturing plant can produce varies jointly as the number of workers and the time that they have

marysya [2.9K]

Answer:

k = 9.64

Step-by-step explanation:

given data

workers w = 305

time t = 2 hour

produce widgets N = 5880.4

solution

we know that here

N ∝ w × t .....................1

when we remove directly proportional so here k constant

so equation will be

N = k × w × t .....................1

put here value and we get

5880.4 = k × 305 × 2

solve it we get k

k = 9.64

The measures of the exterior angles of an octagon are x°, 2x", 3x°, 4x °, 6x°, 7xº,

Neporo4naja [7]

Answer:

216

Step-by-step explanation:

Total of octagon amount is 1080, so set it equal.

x + 2x + 3x + 4x + 6x + 7x + 8x + 9x = 1080

45x = 1080

/45 /45

x = 24

Then plug in for largest number.

9 (24) = 216
