Answer:
Step-by-step explanation:
Given:
'y' varies inversely with 'x'.
When
An inversely proportional relationship is of the form:
Now, in order to get the equation for the given inverse relationship, we need to find the value of the constant 'k'.
So, we plug in the given values of 'x' and 'y' in the above equation and solve for 'k'. This gives,
Therefore, the equation becomes:
Hence, the first option is the correct answer.
Answer:
Step-by-step explanation:
The first step is to realize that this is a geometric sequence, where each next term in the sequence is 2.5 times larger than the previous. You can confirm this by the fact that 3=1.2*2.5, 7.5=3*2.5, and 18.75=7.5*2.5. Now, you can write the formula, where n is where the number is in the sequence, and a is the number itself. Since 1.2 is the first term in the sequence and the rate of expansion is 2.5, the formula is:

D, I already took the testz
12 - 1/4n
90% sure this is right
Okay so a triangle has 3 vertices therefore 3 angles and 3 sides.
Let's first first the other angle not mentioned.
30+40=70 180-70=110
So the other angle is 110°.
If all the sides are different then this is an scalene triangle Kevin drew since the side and angle measurements are different. Scalene triangles have no equal sides or angles, everything is different!!
