Using the strategies
previously discussed

, find the
area of the three
shaded figures below.
Remember that you
can count the squares
as your easiest
strategy,
but I would like for
you to use a
mathematical
strategy to find the
area of the shaded
regions. Beware of
the squares in Figure
C that are not whole
units.
Answers
Answer
A- 22 square units
B- 28 square units
C- 18 square units
Step-by-step explanation:
A. You can break it up into 3 different rectangles
(1*2)+(2*4)+(2*6)=22
B. You can first start by finding the area then subtracting the the places where it is not covered.
So the area of the whole square is 6*6=36
Now you can subtract the small squares 2*2=4.
This will be put 2 times as there are two small squares.
So you will subtract 8 square units from 36.
36-8=28
C- You can decompose C into a triangle and a rectangle.
The area of a triangle is 1/2*width*height. When you plug the dimensions in you get 1/2*6*2=6 square units.
Now to find the rectangle. The formula is width*length. Plug the dimensions in and you get 2*6=12 square units.
Just add those two together and you get 18 square units.

Tonya plans to join a fitness club. She researched the costs to join different clubs in her area and found that there is a linear relationship between the total cost of belonging to a club and the number of months that you are a member. Each club charges monthly dues, and some clubs require new members to also pay a one-time membership fee. The total costs of being a member for 6 months, 12 months, and 24 months at each of three clubs are shown in the table.
Total Cost of Fitness Club Membership
Length of membership
Club 1
Club 2
Club 3
6 months
$108
$120
$126
12 months
$216
$210
$252
24 months
$432
$390
$504
How many of the clubs require new members to pay a one-time membership fee?
A: 0
B: 1
C: 2
D: 3
Answers
The number of clubs that require new members to pay a one-time fee is one.
In order to determine which fitness club requires a one-time membership fee, the average cost per month for each club has to be determined.
Cost of membership per month = cost / number of months
Average cost of Club 1
Average cost for 6 months = $108/6 = $18
Average cost for 12 months = $216 / 12 = $18
Average cost for 24 months = $432 / 24 = $18
The average costs each month is the same. This means that there is no one-time membership fee in this club.
Average cost of Club 2
Average cost for 6 months = 120 / 6 = $20
Average cost for 12 months = $210 / 12 = $17.50
Average cost for 24 months = $390 / 24 = $16.25
The average costs each month is not the same. This means that there is a one-time membership fee in this club.
Average cost of Club 3
Average cost for 6 months = $126 / 6 = $21
Average cost for 12 months = $252 / 12 = $21
Average cost for 24 months = $504 / 24 = $21
The average costs each month is the same. This means that there is no one-time membership fee in this club.

The width of the fountain in Luke's drawing from the example is 2 cm. What is the width of the fountain in Isabella's scale drawing?
Answers
Answer:
2.5cm
Step-by-step explanation:
If Luke's scale for his drawing is 5m to 2cm, then it means that every 2cm on Luke's scale drawing represents 5m in real life. So since the width of the fountain is 2cm, the actual fountain width must be 5m. As established in the example, Isabella's scale factor from drawing to real life is 6/3=2, which means any measurement in cm on her drawing can simply be multiplied by 2 to obtain the real life measurement in m. So, to convert back the other way, from real-life to drawing, we just need to divide the value by 2 instead of multiply. So, if the real life value is 5m, then the width on her scale drawing should be 5/2 = 2.5cm.
Hope this helped!
Using proportions, it is found that:
The width of the fountain in Isabella's scale drawing is of 1.6 cm.
-----------------------------------
This question is solved by proportions, using a rule of three.
Isabella's scale is of 6m to 3cm, that is, 2m to 1cm.Luke' scale is of 5 m to 2 cm, that is, 2.5m to 1 cm.From this, it can be taken that a drawing of 250cm in Luke's scale is of 200 cm in Isabella's scale.What is the width of Isabella's drawing, considering that Luke's width is 2 cm?200 cm - 250 cm
x cm - 2 cm
Applying cross multiplication:
[tex]250x = 400[/tex]
[tex]x = \frac{400}{250}[/tex]
[tex]x = 1.6[/tex]
The width of the fountain in Isabella's scale drawing is of 1.6 cm.

A bicyclist traveled with a speed of 12 km/h from a camping ground to a station, located 60 km away. Write a formula expressing the dependence of the variable s on t, where s is the distance between the bicyclist and the station in km, t - the duration (time) of his travel in hours. Using the formula, find: s for t=3.5
Answers
for t = 3.5 hours
velocity = distance / time
distance = velocity x time
distance = 12 x 3.5 = 42 km
Part b:
for s = 30 km
velocity = distance / time
time = distance / velocity
time = 30 / 12 = 2.5 hours
