The length of each side is 50 inch/ 600 ft
Step-by-step explanation:
Given,
The perimeter of the square park = 12 inches
1 inch = 200 ft
12 inches = 12×200 ft = 2400 ft
To find each side of the park.
Let, each side be 'a' inches
Formula
The perimeter of a square = 4a
According to the problem,
4a = 2400
or, a = 600 ft
= 50 inch
Answer:
A. 2.3km
Step-by-step explanation:
Since 2cm = 1km
4.6cm = xkm
xkm = 4.6 x 1 / 2
= 2.3km
The time × 1.5=the distance
so 5×1.5=7.5
10×1.5=15
20×1.5=30

Answer:
Step-by-step explanation:
10 students participated in a Mathematics quiz. If the number of girls is 4 more than the number of boys, find the number of boys and girls who took part in the quiz
Solution: Number of girls = x
Number of boys = y
x + y = 10 -------------------(I)
Number of girls is 4 more than the number of boys
x - y = 4 ----------------------(I)
x = 4 + y
Substitute x = 4 +y in equation (I)
4+ y + y = 10
4 + 2y = 10
2y = 10-4
2y= 6
y = 6/2
y = 3
Plug in y = 3 in eqution (I)
x + 3 = 10
x = 10 - 3
x = 7
Number of girls = 7
Number of boys = 3
x=3
Step-by-step explanation:
24/x =x+15
24-15=x^2
x=3
