Looking at the two black dots
5 bulbs cost $9
Divide total cost by number of bulbs bought:
9 / 5 = $1.80 per bulb.
10 bulbs cost $18
Divide total cost by number of bulbs bought:
18 / 10 = $1.80 per bulb
The cost for one bulb is $1.80
Answer:
A. 6c = t
Step-by-step explanation:
- 6 c- chairs for each table.
- for example
- 3 table, so 6 chairs for each table 3 * 6 = 18.

Answer:
<u>PART:A</u>

<u>PART:B</u>

<u>PART:C</u>

Step-by-step explanation:
<u>PART:A</u>
When the four officers are chosen than the number of ways of doing this is:

since we have to choose 4 officers and also they need to be arranged according to their ranks.
Hence, the numbers of ways doing so is:

<u>PART:B</u>
Now we have to choose 2 members out of the remaining 6 members so the we have to use combination since we have to just choose the members and do not have to rank them or in short we can say we do not have to arrange them.
Hence, the number of ways doing this is:

Hence, the number of ways of doing this is: 15.
<u>PART:C</u>
Now this process of doing so is also same as the above.
Hence, the number of ways of doing so is: 15.
Step-by-step explanation:
length of each rectangle= 9 1/14=127/14
breadth of each rectangle=5=4 1/2= 9/2
so perimeter of 1 rectangle= 2(l+r)
=2(127/14+ 9/2)
=2(127+63)/14
=2×190/14
=190/7
=27.14 feet
so total length of fencing= 4×27.14
=108.57 feet
hope you understand the solution and good luck!!
