Answer:
15 students per month
Step-by-step explanation:
The rate of change is calculated as
f(b) = 95 ← number of students in October
f(a) = 65 ← number of students in August
b - a = 2 ← difference in months
Thus
rate of change = = = 15
Answer & Step-by-step explanation:
Let's have
C = Creepers
B = Balloons
1) 6C + 20B = 11.9
2) 2C + 15B = 6.05
Eliminate
16C + 20B = 11.9 x3
-2C + 15B = 6.05 x4
18C + 60B = 35.7
-8C + 60B = 24.2
10C/10 = 11.5/10
C = 1.15
We know that
∠ECD=∠ACB------> given in the problem
∠DEC=∠CAB------> 90°
so
∠EDC=∠ABC
therefore
triangles EDC and ABC are similar
<span>So
the ratio of the legs are equal</span>
the answer isAC is equal to 126
