Scientific notation of 0.000125
tester [92]

Answer:

1.25 × 10^-4

Move the decimal until it's at 1.25. You had to go right 4 times so it's negative. If it were 12500 then you'd do it until it was 1.2500 which would be going left so it'd be a positive 4

11Alexandr11 [23.1K]

Answer:

w<50

c≤30

6w+2c≥320

Step-by-step explanation:

W stands for the car wash, and C stands for the cakes. Naturally, it would be 7w+4c≥320 but each cake costs $2 to make and each car wash costs $1 per car. This makes the system 6w+2c≥320. They will wash less than(<) 50 cars and bake no more than(≤) 30 cakes. I hope this helped :).
