12 times 8=96
6x=96
Divide by 6
X=16
12^2+16^2= 400
Sq rt of 400 =20
Answer D
Answer:
Apply cosine rule:
c²=b²+a²-2ba cosC
C= pi/3 = 180/3 = 60 degrees
cosine 60 deg = 0.5
c²=2²+3²-[2×2×3×0.5]
c²=7
c=√7
c=2.645 ;length of third side of angle

Answer:
12/11 = 1 1/11 hours
Step-by-step explanation:
The total rate is the sum of the individual rates in rooms per hour.
Tom can paint 1/4 room per hour.
Sam and Victor can each paint 1/3 room per hour.
Their total rate is ...
1/4 +1/3 +1/3 = 11/12 . . . rooms per hour
The rate in "hours per room" is the inverse of this.
It takes them 12/11 = 1 1/11 hours to paint one room.

Represent them on number line
Start by getting the LCM of the denominators of the three fractions;
The denominator are: 3 and 5
This means that, the number line will be divided into 15 partitions;
Next, we get the position of each fraction as follows;
<em>Jean will be represented on the 10th point</em>
<em></em>
<em>Terry will be represented on the 5th point</em>
<em></em>
<em>Steve will be represented on the 3rd point</em>
<em></em>

-7 +6 would equal -1
-7 and +6 are different signs so subtract and use the sign of the larger number <span />
