Answer:
after one day, 96.8 % are still there
and from this portion will remain 96.8% one day later
so you multiply 0.968 by itself seven times
0,968^7 = 0.7964
<h3>After one week there are 79.64 % left.</h3>

Answer:
15 inches
Step-by-step explanation:
x+5+2x-3+7x+1=103
10x+3=103
10x=100
x=10
The length of other leg is 60 units.
Step-by-step explanation:
Given,
Length of one leg = a = 45 units
Length of other leg = b
Length of hypotenuse = c = 75 units
Using pythagoras theorem
Taking square root on both sides
The length of other leg is 60 units.

Answer:
17) x = 10√2
18) x = 4√6
Step-by-step explanation:
These problems rely on your knowledge of the side ratios of special triangles
45°-45°-90° triangle: 1 : 1 : √2
30°-60°-90° triangle: 1 : √3 : 2
__
17) 5 is the short side of the isosceles right triangle, so its hypotenuse is 5√2. That length is the shortest side of the 30/60/90 triangle, so its longest side is 2 times that:
x = 10√2
__
18) 8 is the longest side of the 30/60/90 triangle, so its long leg will be 8(√3)/2 = 4√3. The hypotenuse of the isosceles right triangle is √2 times that, so ...
x = (4√3)(√2)
x = 4√6
