Answer:
The answer is C, use a calculator and you'll get the answer.
Answer:
Step-by-step explanation:
see the attached figure to better understand the problem
Let
c -----> the cost of some taxi journeys
n ----> the number of miles
we know that
The graph is a line
The equation of a line in slope intercept form is
where
m is the slope
b is the c-intercept (value of c when the value of n is equal to zero)
Observing the graph we have the points
(0,2.5), (5,5.5)
<em>Find the slope</em>
The formula to calculate the slope between two points is equal to
substitute the values
we have
-----> because the point (0,2.5) is the c-intercept
substitute in the equation of slope-intercept form
Answer:
19
Step-by-step explanation:
Here we have to find out number of people attended the party. we are given with the number of the handshakes in the party .
We are going to use the following formula to determine the number of guests
Nos. of handshakes
Here we have H = 171
Hence our equation becomes
now we solve it by splitting the middle term method
Now we have to find the factors of 342 whose difference to 1. The factors are 19 and 18 in this case. hence we slit our middle term like this
Hence
either
(x+18)=0 or (x-19) =0 Thus
x=-18 which is not possible as no of people can not be less than 0
x=19 which will our answer
Answer:
720
Step-by-step explanation:
6 x 120=720
Every 1 cm=120 km
So multiply both sides by 6 and you get
6 cm= 720 km
