A parachutist falls at a speed of about 12 miles per hour. Find this speed in feet per second
padilas [110]
So in 1 hour, the parachutist will fall 12 miles or
12 mi/1hour

convert
1 hour=60 mins
1 min=60 seconds
1 hour=60 times 60 seconds=360 seconds
12 miles per 360 seconds


convert miles to feet
5280 feet per mile
12 miles times 5280=63360 feet

63360/360
do the math and simplify
63360/360=6336/36=176

176 feet per second

Find two consecutive whole numbers that the square root of 105 lies between
erastovalidia [21]

Answer: 10 and 11, also -11 and -10

Sqrt 100 is well known to be 10

Sqrt 121 is 11

Step-by-step explanation:

Positive Sqrt is monotone increasing

So Sqrt 105 is between sqrt 100 and sqrt 121


Second answer

Sqrt 100 is less well known to also be -10

Negative sqrt is monotone decreasing

Sqrt 121 is also -11

Sqrt 105 is also between -121 and -100

Help I don't know what to choose
Lunna [17]

Answer:

Step-by-step explanation:

We know a triangle adds up to 180 so:

75+36+ ? = 180

111+ ? =180

? = 69

To find out x, we know that a straight line adds up to 180 so again:

x +69 = 180

x = 111
