Scientists who make predictions about sea-level rise have to consider several factors. Currently, scientists estimate that sea levels are rising at 4 mm/year, but this rate is expected to increase.

4. If the ocean continues to rise at this rate, how many meters higher will the ocean be in 75 years?

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral

9 x 8 divided by (5-3)=36

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
