A scale drawing of a rectangular park is 5 inches wide and 7 inches long. The actual park is 280 yards long. What is the area of the actual park, in square yards? 35? 200? 1,400? 56,000?
Answer:
56,000
Step-by-step explanation:
The scale drawing is a 1/40 ratio so you multiply 5 by 40 and you get 200. You do 200x280 and you get 56,000.
Maria had 4 full cement, blocks & one that was 5/9 the normal size, If each full block weight 3 8/9 pounds, What is the Weight blocks maria has? (20 POINTS!)
The total Weight blocks maria has is 15.2 pounds.
What is Fraction?A fraction represents a part of a whole.
Given that Maria had 4 full cement, blocks & one that was 5/9 the normal size.
Each full block weight [tex]3\frac{8}{9}[/tex] pounds
We need to find the Weight blocks maria has
Let us convert the mixed faction to improper fraction
35/9 = [tex]3\frac{8}{9}[/tex]
As there are 4 full cement, blocks
So multiply 4 with [tex]3\frac{8}{9}[/tex]
4×35/9
4×3.8
15.2
Hence, the total Weight blocks maria has is 15.2 pounds.

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
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.

A survey found that 12 out of every 15 people prefer eating out over cooking. If 500 people took the survey, how many people prefer eating out?
Answer:
400 people
Step-by-step explanation:
15 = 12
500 = x
Cross multiply
15x = 12 × 500
Divide both sides by 15
[tex]\frac{15x}{15}[/tex] = [tex]\frac{12 * 500}{15}[/tex] (* means multiplication if you do not know)
[tex]\frac{12 * 500}{15}[/tex] = 100 × 4= 400 people

2500m2
Step-by-step explanation:
A square has four sides and the area is 10,000 m^2. Area is determined by multiplying two sides. In this case, you can divide by two to get 5000, then again by 2 to get 2500. Each side/dimensions are 2500m^2

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?
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.
