Answer:
area: A = 8 m^2
Step-by-step explanation:
Area of a rectangle: A = ab
Answer:
42.1 cm
Step-by-step explanation:
θ = 265°
Radius (r) = 9.1 cm
Arc length of major arc GH = θ/360 × 2πr
Plug in the values into the equation
Length of arc GH = 265/360 × 2 × π × 9.1
= 42.0886149
= 42.1 cm (nearest tenth)
ANSWER
or 
EXPLANATION
For 
We make y the subject to obtain,

We can easily graph this function, because we just have to transform the graph of
by shifting the intercept up to
.
As for the straight line,
,
We find the intercepts as follows,
When
.
When
.
We plot the points
and
.
We now draw the two graphs on the same graph sheet. The intersection of the two graphs gives the solution to be
or

Jean's car :
(12 1/2) / (5/12) =
(25/2) / (5/12) =
25/2 * 12/5 =
150/5 =
30 miles per gallon
Miranda's car :
(20 5/7) / (5/7) =
(145/7) / (5/7) =
145/7 * 7/5 =
145/5 =
29 miles per gallon
most fuel efficient is Jean's car....it gets 30 miles per gallon
