arc length = pi /180 * angle in degree * radius
2 = pi/180 * 30 *r
2 = pi/6 *r
multiply by 6/pi
12/pi =r
3.819718634 =r
Answer: r =3.82 inches
Answer:30° - 3d ≤ 20°
Step-by-step explanation:
We have to represent the rate of temperature decrease in degrees .We will represent this by "d" which stands for degree.
According to the question , temperature decreased at a constant rate in the next three days
Therefore , the total decreasing in three days = 3d degree i.e 3 *d=3d
Temperature on Monday = 30°
Then the temperature on Thursday is this = 30° - 3d
Since, The swimming pool is open when the high temperature is higher than 20°=≤20
= 30° - 3d ≤ 20°
This is the required inequality to determine the rate of temperature decrease in degrees Celsius per day, "d"from Monday to Thursday.
Answer:
$17.12
Step-by-step explanation:
First let's find the normal cost with tax
7/100*19=133/100=$1.33
$19+$1.33=$20.33
Now we find the cost with tax for the Valentine's Day price
7/100*35=$2.45
$35+$2.45=$37.45
Now we subtract the normal cost from the Valentine's Day price
$37.45-$20.33=$17.12
Answer: I think 28 miles
Step-by-step explanation:
you add 8 miles every 2 hours until you reach 9 hours and since 9 is an old number you add 4 instead.
