Step-by-step explanation:
3x-2
For this case we have that by definition of trigonometric relations of a rectangular triangle that, the sine of an angle is given by the opposite leg to the angle on the hypotenuse of the triangle.
That is to say:
We clear the length of the leg:
Answer:
Answer:
{7, 8, 9, 10}
Step-by-step explanation:
Having worked 4 hours babysitting, Zoé has already earned 4×$7 = $28, so only needs to earn $130 -28 = $102 more.
At $15 per hour, it takes her $102/$15 = 6.8 hours to earn that amount. In order to keep her total hours to a maximum of 14, Zoé cannot work any table-clearing hours more than 14 -4 = 10. The possible solutions for Zoé's hours doing table clearing are ...
{7, 8, 9, 10} . . . . hours
_____
We have assumed Zoé must work whole numbers of hours.
Answer:
4.5 hours
Step-by-step explanation:

2 miles = 1.5 hours
6 times 1.5 = 4.5
Therefore, 6 miles will take 4.5 hours.
