Answer: 1/10
Step-by-step explanation: -2/5+1/2=0.1
If we convert 0.1 into a fraction, it becomes 1/10.
Answer:
the answer is a, c and d
a. a=180(n-2)
c. n=a/180+2
d. n= a+360/180
Step-by-step explanation:
Answer:
AC = 13.38 miles
BC = 12.65 miles
Where C is the fire location
Step-by-step explanation:
Two fire-lookout stations A and B are 14 miles apart.
The bearing of the fire from station A is Upper N 35 degrees E .
This implies that angle A = 90-35= 55°( reason because B is directly NE of A)
bearing of the fire from station B is N 30 degrees W.
This signifies that angle B is 90-30 =60°
Let's call the fire position C
Angle C = 180-60-55
Angle C= 65°
For Side AC
AB/sin C = AC/sin B
14/sin 65 = AC/sin 60
AC = 13.38 miles
For Side BC
BC/sin A = AB/sin C
BC = sin 55 * (14/sin 65)
BC = 12.65 miles
Answer:
5 men should be subtracted.
Step-by-step explanation:
This question is solved by proportions, using a rule of three.
As these measures(number of men needed and time) are inversely proportional, we multiply the lines instead of cross multiplication.
How many men should be working to complete the work in 32 days?
20 men - 24 days
x men - 32 days
Then
How many men should be subtracted?
There are 20 to complete in 24 days.
15 are needed to complete in 32 days.
20 - 15 = 5
5 men should be subtracted.
