Answer:
<em>Bree spoke at 55 assemblies in this district.</em>
Step-by-step explanation:
Bree speaks at school assemblies charging a school district a total cost C modeled by the equation:
C(a) = 50a+1,500
Being a the number of assemblies attending the meeting.
It's given Bree charged the Escambia City School District $4,250 to speak at school assemblies.
We can find the number of assemblies by solving the equation:
50a+1,500=4,250
Subtracting 1,500:
50a=4,250-1,500=2,750
Dividing by 50;
a = 2,750 / 50=55
Bree spoke at 55 assemblies in this district.
The formula for simple interest is:
Total = Principal(1+ Rate x time)
You are given:
Total = $100
Principal = $20
Rate = 4%
You are asked to find the time.
Replace everything known in the formula:
100 = 20(1 +0.04 x Time)
Now solve for Time:
Divide each side by 20:
5 = 1 + 0.04 x Time
Subtract 1 from each side:
4 = 0.04 x time
Divide each side by 0.04:
Time = 4 / 0.04
Time = 100 years.
Answer:
units
Step-by-step explanation:
The Line 1 has equation x + y = 5 ....... (1) , and
Line 2 has equation x + y = 3 .......... (2)
Now, we have to find the perpendicular distance between line 1 and line 2.
We can say that (3,0) is a point on line 2 as it satisfies the equation (2).
Now, the perpendicular distance from point (3,0) to the line 1 will be given by the formula
units (Answer)
We know that the perpendicular distance from any external point () to a given straight line ax + by + c = 0 is given by the formula .
