Part A :
80x0.18= 14.4
Part B :
80x 0.075= 6
Part C
14.4+6 +80=$100
Answer:
1/6 of a pizza
Step-by-step explanation:
We need to take the amount of pizza and divide by the number of students
8/12 ÷ 4
Copy dot flip
8/12 * 1/4
8/48
Divide the top and bottom by 8
1/6
Each person will get 1/6 of a pizza
I do not know how many slices because it depends on how many slices each pizza is cut into.
Answer:
-15/2 or -7.5 or -7½
Negative StartFraction 15 Over 2 EndFraction
Step-by-step explanation:
Slope or gradient of a line is the ratio of change in y co-ordinates to the change in x co-ordinates.
Therefore;
M=∆y÷∆x
The change in y co-ordinates is given by
∆y=y2-y1
Similarly, change in x co-ordinates is given by
∆x=x2-x1
Given the two points as (5, 80) and (7, 65)
X1=5 Y1=80
X2=7 Y2=65
∆y=65-80=-15
∆x=7-5=2
Hence ∆y÷∆x will be -15÷2=-7.5 or -7½
Negative StartFraction 15 Over 2 EndFraction
we know that
Using the original score as the basis
If Misha increased her test score from
% to
%
then
the increase variation is equal to
%-
%=
%
to find the approximate percent increase of Misha's test score we apply a rule of three
if
%--------------> represents
%
%----------------->x

%
therefore
the answer is
the approximate percent increase of Misha's test score is
%
