A car is traveling at 55 mi/hour. What is the cars speed in feet per second
Shalnov [3]

Answer:

<em>80.7 ft/sec</em>

Step-by-step explanation:

You need two conversion factors:

1 mile = 5280 ft, so (52780 ft)/(1 mile) = 1

1 hour = 3600 seconds, so (1 hour)/(3600 seconds) = 1

55 mi/hour * (5280 ft)/(1 mile) * (1 hour)/(3600 seconds) = 80.6666... ft/sec

Answer: 80.7 ft/sec

How could you explain the sine and cosine relationships to someone who doesn't know about the unit circle? What visuals could yo
sukhopar [10]
If you have a unit circle, it means that you have a circle of radius r = 1 unit. So if we consider the scalene triangle of the figure, its vertical side is the sine of the theta angle and its horizontal side is the cosine of the theta angle. Then to find the hypotenuse of the triangle you use the Pythagorean theorem, thus relating the sine and cosine measures. I attach the solution.

valentina_108 [34]

Answer:

22 groups of ten

Step-by-step explanation:

121 plus 116 = 237

237 - 9 = 228

lets split 228 into parts

200

20

8

there are 20 groups of ten in 200

2 groups of ten in 20

and 8 has 0 it is a remainder

20 groups plus 2 groups = 22

22 groups of ten

this probobly isn't the easiest way but I don't know how but this is my thought process.

Which expression represents the phase below? 8 less than the product of 6 and a number, x
faust18 [17]
The statement is "8 less than the product of 6 and a number, x." "Less than" indicates subtraction - you will subtract 8 from a number. That number is "the product of 6 and a number, x." "The product" of these numbers will result with multiplication - you are multiplying 6 and x.

All this gives you the expression: 6x - 8.
