Answer:
a. $1.66
Step-by-step explanation:
We have been given that Health and Heart Club charges $259 per year. A person has 3 visits per week. We are asked to find the cost of per visit to Health and Heart Club.
We know that there are 52 weeks in one year. So total visits in one year would be 3 times 52 that
visits.
Now, we will divide total cost by 156 to find cost per visit.


Rounding to nearest hundredths, we will get:

Therefore, the cost per visit is $1.66 and option 'a' is the correct choice.
Answer:
19
Step-by-step explanation:
When 2 chords intersect then the product of the parts of one chord equal the product of the parts of the other chord, that is
12(x - 7) = 4(x + 3) ← distribute parenthesis on both sides
12x - 84 = 4x + 12 ( subtract 4x from both sides )_
8x - 84 = 12 ( add 84 to both sides )
8x = 96 ( divide both sides by 8 )
x = 12
Thus
12 + x - 7 = 12 + 12 - 7 = 17
4 + x + 3 = 4 + 12 + 3 = 19 ← longer chord
Answer:
B
Step-by-step explanation:
The vertex of the parabola is (-1,-4)
So the axis of symetry is x=-1
Odd function must pass through origin so first two options are not correct.
Odd function must be rotational symmetry around origin. So last option is not correct.
So answer is C.
Heat touching the surface of the ice cube causes it to melt. So a cube with larger surface area will allow more contact with the heat as compared to the cube with small surface area.
If the amount of heat that is being transferred to the ice cube from the surrounding environment is more, it will melt more quickly. If the ice cube melts more quickly it cannot serve its purpose i.e. to cool down the liquid it is dipped into.
Therefore, for better results, the surface area of the ice cube should be less, so that less heat touches its surface and the process of melting is slow.
