Mathematics

First, add up the parts of the ratio...
2+3+5=10
then divide the whole into individual parts...
25/10=2.5
then multiply the value of 1 part by the amount in the ratio...
2.5 x 2  =5
2.5 x 3 = 7.5
2.5 x 5 = 12.5
so the final ratio is 5kg:7.5kg:12.5kg
Hope this helps :)

Six numbers from a list of nine integers are $7$, $8$, $3$, $5$, $9$, and $5$. What is the largest possible value of the median
laiz [17]

8  is the largest possible value of the median of all nine numbers in this list.

Lets simplify it,

⇒  The given six numbers are 7,8,3,5,9 and 5.

⇒  Arrange the six numbers in order 3,5,5,7,8,9.

⇒  We have three more numbers to insert into the list, and the median will be the  highest 5(and 5 lowest) number on the list. If the three numbers are greater than 9, the median will be the highest it can possible be.

∴  The median is the 5th item of data which is 8.

∴  Median=8

Hence 8  is the largest possible value of the median of all nine numbers in this list.

In 1970, a farmer using a two-row combine with a corn head could easily harvest 0.75 ha (1.85 acres) per hour and a typical corn
Anastaziya [24]

Answer:

The value is w = 6.7 \%

Step-by-step explanation:

Generally the productivity rate is mathematically represented as

P_r =  K  * Z

Here K is the ha the farmer could harvest in an hour and Z is a typical yield of corn in kg/ha

Now considering 1970

The productivity rate is

P_r =  0.75   *5000

=> P_r =  3750 \  kg/h

Now considering 1940

The productivity rate is given as P_R =  250 \ kg/h

Generally the productivity ratio is mathematically ration is mathematically represented as

w =  \frac{P_R}{P_r}  * 100

=> w =  \frac{250}{3750}  * 100

=> w = 6.7 \%

A bicycle is traveling at 16 miles per hour. How many feet will it cover in 35 seconds? Round your answer to the nearest tenth o
ch4aika [34]

A  bicycle is traveling at 16 miles per hour it covers 821.33 ft in 35 seconds.

It is required to find How many feet will it cover in 35 seconds.

<h3>What is conversion?</h3>

conversion is the process of changing the value of one form to another for example inches to millimeters, or liters to gallons. Units are used for measuring length, measuring weight, measuring capacity, measuring temperature, and measuring speed.

Given that:

1 hour = 60min×60sec = 3600 sec

1 miles = 5280 feet

16 miles = 16×5280ft = 84480 ft

3600sec ................. 84480  ft

35sec ................................ x ft

x = 35×84480/3600

=2956800 /3600

= 821.33 feet.

Hence, a bicycle is traveling at 16 miles per hour it covers 821.33 ft in 35 seconds.
