7 girls participated only in Karate.
21 + 8 = 29
29 + 7 = 36
36 + 6 = 43
(1/10)m = (1/11)m +1/1100
(1/10 -1/11)m = 1/1100
(1/110)m = 1/1100
m = (1/1100)/(1/110) = 110/1100
m = 1/10
Answer:
(a)
Area: 930 meters(m)
Perimeter: 122 meters(m)
(b)
Area: 616 centimeters(cm)
Perimeter: 116 centimeters(cm)
(c)
Area: 1008 millimeters(mm)
Perimeter: 128 millimeters(mm)
Explanation:
Area = length x width
Perimeter = length+width+length+width
Area for (a) is then 31 times 30 = 930
Area for (b) is then 44 times 14 = 616
Area for (c) is then 36 times 28 = 1008
Perimeter for (a) is 31+30+31+30=122
Perimeter for (b) is 44+14+44+14=116
Perimeter for (c) is 36+28+36+28=128

Answer:
x+y<20andx+5y>40
Step-by-step explanation:
The inequality for the number of coins is ...
x + y < 20
The inequality for the value of the coins is ...
x + 5y > 40
Answer:
add up all the sides and angles then divide by the radius to get the square centimeters and it will lead to the surface area which is 14
Step-by-step explanation:
I had to calculate to double check
