Answer:

d. 0.019 years of age per year

Step-by-step explanation:

The average rate of change over the ninety-year period described in the table is obtained as follows:

average rate of change = (median age in last year - median age in the first year) / (last year - first year) = (26.8 - 25.1)/(2000 - 1910) = 0.019

A. .019 years of age per year

rate of change is \frac{26.8-25.1}{2000-1910} =  \frac{1.7}{90} = .019

Hope that helps.

Can someone pleaseee help!!!
krok68 [10]

Answer:

Step-by-step explanation:

use known angles and rules to find unknown values

vertical angles (pairs of angles on opposite sides of an intersection) are equivalent

supplementary angles (angles found next to each other on a line) add up to 180 degrees

opposite interior angles are equivalent

And I don't remember the name of this kind of angle, but angle 1 and 10 are equivalent because they are found on the same "location"

using these rules you can find all missing angles.

1= 75

2=180-75=105

let me know if you need more help than this

A circular race track has a radius of 200 feet a car drives 50 laps around the track approximately how many miles does the car t
bazaltina [42]

Answer:

  11.9 miles

Step-by-step explanation:

The length of the track is ...

  C = 2πr = 2π(200 ft) = 400π ft

Then the length of 50 laps will be ...

  50C = 50·(400π ft) = 20,000π ft ≈ 62,831.9 ft

The number of miles (m) this is can be found from ...

  m(5280 ft) = 62,831.9 ft

  m = 62,831.9/5280 ≈ 11.90 . . . . miles

50 laps is about 11.9 miles.
