49.73</h2><h2>
</h2>
Step-by-step explanation:
total area = area of rectangle - area of circle
= (13 x 6) - (π 3²)
= 78 - 28.274
= 49.73 sq. units
Answer:
the first oe
Step-by-step explanation:
The density of the liquid is 1.55 g/mL.
Given the following data:
Mass of liquid = 22.8 grams
Volume of liquid = 14.7 mL
To find the density (unknown) of the liquid:
Density is mass all over the volume of a substance or an object. Thus, density is mass per unit volume of an object.
Mathematically, the density of a substance is given by the formula;
Substituting the values into the formula, we have;
Density = 1.55 g/mL
Therefore, the density of the liquid is 1.55 g/mL.

Kory and Leanne will meet each other again after 36 minutes from starting i.e. at 10:36 am .
<u>Step-by-step explanation:</u>
Here we have , Leanne runs a lap in 12 minutes. Kory runs a lap in 9 minutes. We need to find out that If they both start running at 10 am, at what time will they both cross the start together again . Let's find out:
Kory runs a lap in 9 minutes and , Leanne in 12 minutes , in order to find at what time will they both cross the start together again we will find LCM of 9 & 12 :
⇒
⇒
So ,LCM of 9 & 12 is 36 .That means Kory and Leanne will meet each other again after 36 minutes from starting i.e. at 10:36 am .
In clear way , Kory will run race as :
1st lap = 9 minutes
2nd lap = 18 minutes
3rd lap = 27 minutes
4th lap = 36 minutes , i.e. at 10:36 am he'll complete his 4th lap
For , Leanne
1st lap = 12 minutes
2nd lap = 24 minutes
3rd lap = 36 minutes i.e. at 10:36 am he'll complete his 3rd lap .
This means Kory & Leanne will meet at 10:36 am completing there 4th and 3rd lap respectively .
We know that the number of workers doubles every week.
This implies that the number of workers of the previous week is exactly half of the current one's.
So, it took 11 weeks for the factory to be at half capacity.
