A parachutist’s speed during a free fall reaches 13 miles per hour. What is this speed in feet peer second? At what speed, how m
pickupchik [31]
We make the corresponding unit change.
 We have then:
 V = 13 * (1/3600) * (5280)
 V = 19.06666667 feet / s
 Then, after 10 seconds, we have by definition:
 d = v * t
 Where,
 v: speed
 t: time
 Substituting the values:
 d = (19.06666667) * (10)
 d = 190.6666667 feet
 Answer:
 V = 19.06666667 feet / s
 d = 190.6666667 feet

Daniel [21]
Hello! To find this answer, we have to do change/original. 9.73 - 9.60= 0.13. 0.13/9.60 = 0.01354 and other numbers behind it or 1.4% when rounded to the nearest tenth. You have to multiply the decimal by 100 in order to to get the percent form. It rounds up to 1.4 instead of back down to 1.3, because the 5 is in the hundredths place, and when anything 5 or more appears behind the digit you are rounding to, you go up. The percent increase is about 1.4%.

Calculate the infant mortality rate (per 1,000 live births) from the following data:________.
Mademuasel [1]

Answer:

Between 1991 and 2013, the infant mortality rate in the United States declined  from 8.943% to 5.708 %  

Step-by-step explanation:

From the information given:

The number of infant deaths under 1 year in the United States during 1991 = 36,766

The number of live births during 1991 = 4,111,000

Infant  \ mortality \  rate \  in  \ 1991 = \dfrac{Number  \  of \ deaths \ under \  1  \ year}{Total \ number \  of \  live \ births \ in \  1991} * 1000

Infant  \ mortality \  rate \  in  \ 1991 = \dfrac{36766}{4111000} * 1000

Infant mortality rate in 1991 = 8.943%

From the data of year 2013 in the United States Record, 23,446 infants died under one year

Infant  \ mortality \  rate \  in  \ 1993= \dfrac{23,466}{4111000} * 1000

Infant mortality rate in 1993 = 5.708 %

Between 1991 and 2013, the infant mortality rate in the United States declined  from 8.943% to 5.708 %   which is approximately 3%
