Step-by-step explanation:
-HCM(GCM)
105's factor are 1, 3, 5, 7, <em>15</em>, 21, 35, 105.
125's factor are 1, 2, 3, 4, 5, 6, 8, 10, 12, <em>15</em>, 20, 24, 30, 40, 60, 120.
so, the answer is 15!
One at 100,18 one at 200,14 one at 150,15 one at 125,20 and one at 225,12
Answer:
182
Step-by-step explanation:
Sum = a(r^n -1) ÷ r - 1
1(-3^6 - 1) ÷ -3 -1
= 182
r = t2 ÷ t1 * since they stated that it is geometric
It’s going to take 29 days to lay all the tracks because 174/6=29
Answer:
(D) 81 feet
Step-by-step explanation:
From the figure drawn, it is given that AB is parallel to DE, in ΔABC and ΔCDE, we have
∠BAC=∠DEC(Alternate angles)
∠ACB=∠DCE(Vertically opposite angles)
Thus, by AA rule, ΔABC is similar to ΔCDE.
Since the line connecting from the whales to the sharks is parallel to the line connecting from the penguins to the fish tanks, the triangles shown in the figure are similar.
Using the property of similar triangles.
Hope this helped!!!
