Answer:
6.1389 x 10^8
Step-by-step explanation:
Answer:
35°
Step-by-step explanation:
Since all straight lines have a degree of 180, we can find the measures of the other two angles.
180-85= 95
180-130=50
The sum of the measures of the degrees in a triangle is 180. So if we add m∠A + 95+50 it should equal 180.
We can solve that equation to get the measure of ∠A.
m∠A +145=180
m∠A=35°
Answer:
The average weight of new born otter was, 
Step-by-step explanation:
Let average weight of new born otter be x.
As per the given statement: At birth it's weight was 7/8 kilograms which is 9/10 kilogram less than the average weight of a new born otter in the aquarium
"
kg less than average weight of a new born otter" means 
As per the given information, we have;

Add
both sides, we have;

Take LCM of 8 and 10 is, 40
⇒
Simplify:

Therefore, the average weight of new born otter was, 
Answer:
a) 6
Step-by-step explanation:
Expanding the polynomial using the formula:

Also

I think you mean 
We can deduce that this term will be located somewhere in the middle. So I will calculate
.
For 

Note that we actually don't need to do all this process. There's no necessity to calculate the binomial, just 
For 

X = 112
