Rita received 24 phone calls on the first evening, and 19 phone calls on the second evening and 48 phone calls on the third evening at the call center.
Step-by-step explanation:
As per given details,
Rita received a total of 91 phone calls at the call center over the last three evenings.
Let us assume the number of phone calls Rita received in the first evening is X.
The second evening Rita received 5 fewer calls than the first evening
=>X-5
The third evening Rita received 2 times as any calls as the first evening
=>2X
Now as given sum of total number of calls received in the three evenings is
X + X-5 + 2X = 91
4X - 5 = 91
4X = 96
X =24.
Therefore total calls received on first evening is X = 24
On the second evening X-5 = 24-5 = 19
On the third evening 2X = 48.
Answer:
C (4,3)
Step-by-step explanation:
Steps to find the circumcenter:
1) Find and Calculate the midpoint of given coordinates or midpoints.
2) Calculate the slope of the perpendicular bisector lines
3) By using the midpoint and the slope, find out the equation of the line
4) Do the same for another line
Solve the equations of two lines to get the intersection point.
The intersection point will be the circumcenter of the triangle.

Answer:
carbon footprint
7.7 tons
Step-by-step explanation:
Given that,
carbon dioxide produced by a car over 7 year period = 53.5 tons
To find,
carbon footprint <em>(tons of carbon dioxide per year)</em>
7 years ------> 53.5 tons
1 year -------> 53.9/7 tons
= 7.7 tons
tons of carbon dioxide produced per year = 7.7
Answer:
Step-by-step explanation:
Let s represent the speed of the bus.
From the information given, the bus needs to cover a distance of 240 km in less than 5 hours. The formula for calculating the speed of the bus, s is expressed as
Speed, s = distance covered by the bus/ time taken to cover the distance
Therefore,
Speed, s = 240/5 = 48 km/hr
A higher speed would ensure the bus covers the distance in less than 5 hours. Therefore, the inequality that represents the speed (s) of the bus would be
s ≥ 48
