Answer
11a + 4a= 15a
3x + 6 +7x -4 = 12x
-12m -3 + 4m + 16 = 29m
6k-4+k-2 =4K
3+13-5p-2p =9p
I think these are the answers please don’t get mad if they are not hope I help :)
Answer:
What is the question?
Step-by-step explanation:
TOTAL NO.OF ANIMALS IN FARMHOUSE=42
RATIO OF COW : BUFFALO=5:9
LET THE NO.OF COWS BE 5X AND BUFFALOES BE 9X
5X + 9X =42
14X=42
X = 42/14
X= 3
TOTAL NO.OF COWS = 5 x 3 =15
TOTAL NO.OF BUFFALOES = 9 x 3 = 27
Y - 2 = x + 3
+ 2 + 2
y = x + 5
Answer:
a). Radius r of the small sector= 12cm
b). Perimeter of the shape= 68 cm
c). Angle= 47.7°
Step-by-step explanation:
a). Radius of the big sector= 24 cm
Arc if the big sector= 20 cm
Arc of the small sector= 10 cm
For the radius r of the small sector
r/10 = 24/20
r=(10*24)/20
r= 24/2
r= 12 cm
Radius r of the small sector= 12cm
b). Perimeter of the shape
= Total length of the shape
Let's note that the other side of the sector is also the radius= 24 cm
Perimeter= 20+24+24
Perimeter of the shape= 68 cm
c) the angle
Length of arc = 2πr*(angle/360)
Let angle = b
Length of arc = 20cm
20= 2*3.14*24*(b/360)
(20*360)/(2*3.14*24)= b
47.7°= b
Angle= 47.7°
