Answer:
1st= 47/7 or 6.71
2nd= 48/7 or 6.857
Step-by-step explanation:
1st number =X and 2nd number = Y
According to question, X+7=2Y
20+Y=4X
X=2Y-7 (from 1st condition)
putting in it second
20+Y=4(2Y-7)
20+Y=8Y-28
20+28=8Y-Y
48=7Y
Y=48/7
so X=2(48/7)-7
=96-49/7
47/7
Answer:
226.8cm^2
Step-by-step explanation:
A=pir^2
24/4 = 6 (radius of small circles)
pi6^2= 113.097335529 times 2 (because theres 2 of them)
=226.8
24/2 = 12 (radius of big circle)
pi12^2= 452.4 minus 226.8 (to get the leftover space)
=226.8
Answer:
x= 1.6 degrees
Step-by-step explanation:
to find the missing angle 180 degrees - 151 degrees
29° is the missing angle at the bottom ryt of the triangle.
all angles in triangle add upto 180°
so, 20x-3°+11x-1°+29°= 180°
31x=180°-25°
x= 1.6°
Answer: 20
