Answer: D. -4F
Step-by-step explanation:
Let's use simple math. 1 - 5 = -4 or -8 divided by 2 = -4, right?
Same idea, so now lets apply it.
If it decreases -8F in only two hours you just simply divide the temperature by the hour.
Looking at problem A that just would not make sense, how could it decrease while staying at the same number?
Problem B also wouldn't make sense because a negitive plus negitive equals a negitive, same with subtracting. So 10 is inncorrect
Problem C also is inncorrect because 8 divided by 2 = 4, not 6
So, D is correct because -8 divided by 2 equals = -4
Hope this helps!
Total length of fence = 420 feet
To fence 3 sides with max area = 420 ÷ 3 = 140 feet
Each side should should be140 feet
Total enclosed area = 140 x 140 = 19600 square feet.
Answer:
k = 1 or 2 or 5 or 10
Step-by-step explanation:
Suppose GCD is k, 2 numbers are kA and kB
LCM is k*A*B,
GCD*LCM: k*(k*A*B) = 200
k² * A*B = 200
A*B could be 1 , 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, 200
k² (k is integer) could be 1, 4, 25, 100
k = 1 or 2 or 5 or 10
Answer:
904.78
Step-by-step explanation:
V = 4/3 pi r^2
4/3 pi 6^2
904.78
So
if increase by 10%, that means times 1.1
sub 1.1r for r in
V=(4/3)pir³
so
nV=(4/3)pir³
nV=(4/3)pi(1.1r)³
nV=(4/3)pi1.331r³
nv=((4/3)pir³)1.331
V=(4/3)pir³
nV=(V)1.331
x times 1.331 is about a 33% increase
