Answer:
Number of cheaper dresses sold is 35
Number of expensive dresses sold is 15
Step-by-step explanation:
Given:
Cost of cheaper dresses = $90
Cost of expensive dresses = $140
Total cost of the dresses = $5250
To Find:
Number of cheaper dress = ?
Number of expensive dress = ?
Solution:
Let
The number of cheaper dresses be x
The number of expensive dresses be y
(Number of cheaper dresses X cost of cheap dress) + (Number of Expensive dresses X cost of expensive dress) = $5250
= $5250
It is given that the 20 more of the cheaper dresses than the expensive dresses is sold
So,
number of cheaper dress = 20 + number of expensive dress
x = 20 + y---------------------------------------(1)
y = 15
Substituting y in (1)
x = 20 +15
x= 35
★ Sanya has a piece of land which is in the shape of a rhombus.
★ She wants her one daughter and one son to work on the land and produce different crops, for which she divides the land in two equal parts.
★ Perimeter of land = 400 m.
★ One of the diagonal = 160 m.
★ Area each of them [son and daughter] will get.
Let, ABCD be the rhombus shaped field and each side of the field be
[ All sides of the rhombus are equal, therefore we will let the each side of the field be ]
Now,
• Perimeter = 400m
Each side of the field = <u>100m</u><u>.</u>
Now, we have to find the area each [son and daughter] will get.
So, For ABD,
Here,
• a = 100 [AB]
• b = 100 [AD]
• c = 160 [BD]
Using <u>herons formula</u><u>,</u>
where
• s is the simi perimeter = 180m
• a, b and c are sides of the triangle which are 100m, 100m and 160m respectively.
<u>Putt</u><u>ing</u><u> the</u><u> values</u><u>,</u>
Thus, area of ABD = <u>4800 m²</u>
As both the triangles have same sides
So,
Area of BCD = 4800 m²
<u>Therefore, area each of them [son and daughter] will get = 4800 m²</u>
