Answer:

350 lightbulbs

Step-by-step explanation:

First find the number of batches made.

20,000 divided by 400 = 50

This means that there are 50 batches in which 7 light bulbs will be selected at random to be inspected.

We can multiply the number of batches to the lightbulbs being inspected.

50 times 7 = 350

Therefore, 350 lightbulbs will be inspected.

Please tell me if I am incorrect :)

clay costs $5.60 per kilogram. The art teacher needs to buy 4.5 kilograms for the next project. How much will 4.5 kilograms of c

RoseWind [281]

Well first you have to multiply 4*5.60 to get the 4.0 kilograms

4*5.60=22.4

then divide 5.60/2 to get the .5 kilograms more she needs.

5.60/2=2.8

then just add 2.8+22.4 to get the whole 4.5

2.8+22.4=25.2

it cost $25.20 to get the whole 4.5 kilograms of clay.
