Answer: 45
Step-by-step explanation: If you evaluate how much 15% of holly trees there were and the 2/5, consisting of maple trees then both of the amounts combined is, 55 then the remainder in of trees, the dogwoods, is 45
1 km = 1000 meters.
Find total meters: 80 km x 1000 meters per km = 80,000 meters.
Divide total meters by the given speed:
80,000 meters / 180 m/s = 444.44 seconds.
1 minute = 60 seconds
444.44. Seconds / 60 seconds per minute = 7.41 minutes = 7 minutes 24.42 seconds
Total time = 7 minutes 24.42 seconds
Round as needed.
Answer:
9 inches
Step-by-step explanation:
Since the triangle are similar then the ratios of corresponding sides are equal
let x be the longer median, then
= 
( cross- multiply )
16x = 6 × 24 = 144 ( divide both sides by 16 )
x = 9
Angle 10 is 140 degrees
Angle 2 = Angle 10 = 140 degrees (Vertically Opposite Angles)
Angle 5 + Angle 4 = Angle 2 (Corresponding Angles)
Angle 5 + Angle 4 = 140
90 + Angle 4 = 140 (Angle 5 is 90 degrees because c is perpendicular to d)
Angle 4 = 50
This is the concept of numbers, given that the G.C.D two numbers (a,b)=6 and the L.C.M (a,b)=180, to find the possible number we do as follows;
L.C.M =a*b=180
since 6 is a multiple of a and b, then the numbers could be:
180/6
=30
hence these numbers could be (6,30)
