Answer:
Ann would need 3 h to complete the remainder of the Job.
Step-by-step explanation:
Step 1.
The "speed" that each girl has to do the work is determined as:
- Tina:
, it means that Tina complete one twelveth of the job each hour. - Ann:
, it means the Ann completes one eighth of the job each hour.
Step 2.
The amount of work done by Tina in 9 hours, is obtain multiplying by the "speed" calculated in step 1:
Amount of work done=
. It means that <em>Tina completes two thirds of the work in 9 h.</em>
Step 3.
The remaining job is calculated as
. It means that <em>still remains is one third of the job to be completed</em>.
Step 4.
The time required for Ann to complete the job is calculated dividing the remaining of the job by the "speed" of Ann to do the job.
. It means that <em>Ann would complete the job in another 3 hours</em>.

Answer:
Multiplication signs are filled in between the numbers to make it a true equation.
Step-by-step explanation:
In mathematics, a true equation occurs when the values on both sides of the equal sign (i.e. =) are the same. For example, 2 + 2 = 4 is a true equation; and 3 * 2 = 6 is a true equation.
For this question, multiplication signs are filled in between the numbers to make it a true equation as follows:
2802 * 1811 * 123 * 441 * 3633 * ⅓ * 32² * 205 = 69,972,637,305,761,000,000
5358+2834+4132=12324
14000-12324=1676
I think they need $1676
c is the answer I think cause it feels right
