Answer:
20,000m²
Step-by-step explanation:
If they jog 12 km/h for half an hour, they have covered.
12 X 0.5 = 6km in 10 circuits. Making 1 perimeter
6 / 10 =0.6 km (600 m).
To determine area we need to convert this perimeter to length and width. We know that it is a rectangle, with 2 equal widths and 2 equal lengths, and the length is twice the width.
So L = 2W
Perimeter = 2W + 2L
600 m = 2W + 2(2W)
600 m = 6W
W = 100 m
L = 200 m
Area = 100 X 200 = 20,000 m²
Answer:
There are 60 different summer reading lists possible.
Step-by-step explanation:
A certain school district has specified 5 different novels and 4 different non-fiction.
Each summer reading list must have exactly 3 novels and 2 non-fiction books.
So, the number of different summer reading lists that are possible is given by:
= 
= 
Hence, there are 60 different summer reading lists possible.
Find the multiples of 25 and 60
25: 25, 50, 75, 100, 125, 150, 175, 200, 225, 250, 275, 300
60: 60, 120, 180, 240, 300
The 300th customer will recieve both gift cards
The first figure, on left, is the composition of two areas, the area of a 7cm circle and the area of a 7 cm square so:
A=7^2+7^2π/4
A=49+49π/4
A=49(1+π/4) cm^2
A≈87.48 cm^2 (to nearest hundredth of a square centimeter)
...
The second figure is the area of a 15cm by 8cm rectangle minus the area of a 3cm circle so:
A=15(8)-3^2π/4
A=120-9π/4
A=120-2.25π cm^2
A≈112.93 cm^2 (to nearest hundredth of a square centimeter)
