Answer with explanation:
Presume that, initial water level to be, 0 mm, at a time t=0.
And water level is rising at the rate of 
.
After 6.2 years level of water will be =1.8 × 6.2
=11.16 mm
→Averge, that is increase in water level after 6.2 years is given by
→→Rate of Depreciating of water level is given by = Negative of Increase of water level=
Answer:
False
Step-by-step explanation:
Because the gcf of 10 and 18 is 2
Answer:
325 miles and 77 dollars
Step-by-step explanation:
First, create equations. Let x equal the miles driven. The first plan expression is 38 + 0.12x and the second plan expression is 51 + 0.08x. Setting these equal and solve for x: 38 + 0.12x = 51 + 0.08x -> 0.04x = 13 -> x = 325 miles.
The cost is found by substituting it into any of the expressions: 51 + 0.08(325) = 77 or 38 + 0.12(325) = 77
Those two angles are complementary - which means they both give us 90
degrees. We know that all three angles in any triangle must be exactly
180 degrees, so the third angle will be 180 - 90 = 90 degrees. It means
that our triangle is a straight triangle. The figure will look more less like in the attachment.
