Answer:
Step-by-step explanation:
32.12 meters below sea level. The diver ascended to the surface at a rate of 8.8 m/min. So the diver ascended 3.65 meters a minute.
a) Use d=rt. D=distance, t= minutes, r=rate
d=8.8t
b) The distance will never be a negative number because you can't have a negative distance to something.
c) 3.65 minutes for the diver to reach the surface.
Let's use the addition/subtraction method.
Suppose we wish to eliminate variable x.
Mult the first eqn by 5: 10x - 15y = 15
Mult the 2nd eqn by -2: -10x+ 4y = -8
Add these two equations together: -11y = 7, and y = -7/11.
Subst. -7/11 for y in either given equation and find x.
Then your solution is (x,y) (subst. the values we've found for x and y).
Answer:
60
Step-by-step explanation:
65% = .65, so
60 × .65 = 39
or the equation could be
60/.65 = x

Answer:
From lowest to highest, the numbers would follow the following order:
1) 4.606, 2) 4.64, 3) 4 + 13/20, 4) 47/10.
Step-by-step explanation:
Given that the numbers 47/10, 4.606, 4 + 13/20 and 4.64 are presented, to order these from lowest to highest, the following calculations must be performed:
47/10 = 4.70
4,606
4 + 13/20 = 4 + 0.65 = 4.65
4.64
Therefore, from lowest to highest, the numbers would follow the following order:
1) 4.606, 2) 4.64, 3) 4 + 13/20, 4) 47/10.
