If she cuts it then the angle would become a right angle so it sould be 90º
Answer:
and 
.
Step-by-step explanation:
Start by adding 1 to both sides of this equation.
.
The square of what number or numbers will lead to the number "1"? It turns out that not only 
, but 
as well. In other words, the value 
can be either 1 or -1. Either way, the equation is still going to hold. That's the reason why there are two solutions to this equation.
Consider the case when 
. Add 10 to both sides of the equation. 
.
Now, consider the case when 
. Again, add 10 to both sides of the equation, 
.
Order the two solutions in an increasing order:
- ,
- .
Answer: 706 grams
Step-by-step explanation:
s(m) = km
So 6000 = 8.5m
Divide both sides by 8.5 to isolate m
6000/8.5 = 8.5m/8.5
705.88 = m
m = 706 (rounding up)
Answer:
6
Step-by-step explanation:
x(0.25) = 1.5
Because the scale factor is 0.25, or 1/4 we can reverse that to get 4/1. Then simply multiply 1.5 by 4!
