Answer:
The answer is below
Step-by-step explanation:
A student on the cross- county team runs 30 minutes a day as a part of her training. Write an equation to describe the relationship between the distance she runs in miles, D, and her running speed, in miles per hour, when she runs at a constant speed of 5.4miles per hour for m minutes, and then at b miles per hour for n minutes
Solution:
Given that the student runs for a total of 30 minutes per day. He runs at 5.4 miles per hour for m minutes, and then at b miles per hour for n minutes.
Hence:
m + n = 30
60 minute = 1 hour. Therefore, m minute = m/60 hour, n minute = n/60 hour.
The distance traveled is the product the speed in miles per hour and the time taken to cover the distance. Distance = speed * time
The total distance ran (D) is:
D = 5.4(m/60) + b(n/60)
Answer:
The answer is 5:12
Step-by-step explanation:
It is 5:12 because We already know that 7 pens are blue. To find the number of red pens we must subtract 12 - 7 and get 5 as the number of red pens. Now knowing the no. of red pens and total number we can say the ratio of red pens to total no. is 5:12
Answer:
The value of y for given log function is 8 .
Step-by-step explanation:
Given as :
The log function is Log 5 + Log y = Log 40
Or, Log y = Log 40 - Log 5 .........1
∵<u> From the Log property</u>
Log m - Log n = Log 
So, Log 40 - Log 5 = Log 
Or, Log 40 - Log 5 = Log 8 .........2
Now, From eq 1 and 2
Log y = Log 8
∴ y = 8
So, The value of y = 8
Hence, The value of y for given log function is 8 . Answer
Answer:
3240
Step-by-step explanation:
If the simple interest is 8%, Mr. Kim will have to pay $3000, and the simple interest, which will be 8% of $3000.
You can write it in two ways:
3000+3000*0.08= 3240
or
3000*1.08= 3240
