Easy
when rock is in water, it takes up a certain volume, say x
so
initial+x=final volume
luckily we have final and inital
13.7ml+x=28.9ml
minus 13.7ml both sides
x=15.2ml
the volme of the rock is 15.2ml
Answer:
67/100
Step-by-step explanation:
67÷100 Divide the numbers
0.67 then move the decimal point to the right
6.7 *10 this will give you the fraction
Tan67=h/137
h=137tan67
h≈322.751 ft
h≈322.75 ft (to nearest hundredth of a foot)
The definition of a function is a relation where every input (x value) is paired with exactly one output (y-value).
A. Not a function, because you have (300, 9) and (300,7). The x-value 300 is paired with two different y-values, 9 and 7.
B. Not a function. (260, 4) and (260, 2)
C. Is a function
D. Not a function. (225, 4) and (225, 2)
