Answer:Lcm (4,6)=12
Step-by-step explanation:Smallest 3 digit no. =100
Divide 100 by 12
100=12*8 +4
That means 12*8 would be the largest multiple of 12 that is less than 100
So 12*9 would be the smallest multiple of 12 that is greater than 100
Therefore the answer is 12*9=108.

Answer:
a) 64° each
b) 15.78 cm
c) 51.78 cm
Step-by-step explanation:
a) (180 - 52)/2 = 64°
b) cos 64 = x/18, x = 7.89, 2x = 15.78 cm
c) 18 + 18 + 15.78 = 51.78 cm
For the first is 3864
The second is 1320
A=3.14(which is pie) x 20.5^2
A=420x pie
A=1320
For the third is 2544
3864-1320=2544
Sorry if this is wrong too.
Answer:
4 and 6
Step-by-step explanation:
Let the smaller number be x
The bigger number be y
Eight times the smaller of two numbers plus two times the larger number is 44.
8x+2y=44
Three times the smaller number minus two times the larger number is zero
3x-2y=0
8x+2y=44
3x-2y=0
Using elimination method
Add both sides
8x+3x+2y+(-2y)= 44+0
11x= 44
x=44/11=4
Put x = 4 back in one of the equation
3x-2y=0
3(4)-2y=0
12-2y=0
Add 2y to both sides
12 = 2y
Divide both sides by 2
12/2 =y = 6
The smaller number (x) is 4 and the larger number (y) is 6
