Answer:6
Step-by-step explanation:
In a circle, a radius perpendicular to a chord bisects the chord. So BC = CA BC = 6 (given) x (or AC) = 6 Answer = 6. Tell me if I was right. Thanks.
Answer:
false
Step-by-step explanation:25.9cm is too big to connect to 15.9cm and 10 cm
An acute angle is an angle less than 90 degrees. (smaller angle)
A right angle is exactly 90 degrees. (right angle)
An obtuse angle is over 90 degrees. (larger angle)
A reflex angle is any angle of 180 degrees. (largest angle)
You wouldn't *really* need a protractor to complete your homework; you could guesstimate.
I hope this helps!
Answer:
let the number of cows = x
let the number of chickens = y
since there are 42 heads:
x + y = 42
and since a cow has 4 legs, and a chicken has 2
4x + 2y = 144
from first equation:
x + y = 42
x = 42 - y (now, we will substitute this in the second equation)
4(42 - y) + 2y = 144
168 - 4y + 2y = 144
2y = 168 - 144
2y = 24
y = 12
now, we know the number of chickens. we will replace y with 12 in the first equation since it is more simpler
x + 12 = 42
x = 30
So, there are 30 cows and 12 chickens

Answer:
C)1/3
Step-by-step explanation:
So there are 18 marbles in all.So the denominator should we eighteen unless we can simplify it.There are 6 yellow marbles,so the numerator can be 6 unless simplified.In this case,the fraction is 6/18.We can simplify it.The GCF(greatest common denominator) is 6.That makes it 1/3.
