5km/25mins equals x km / 1min
or x=1/5, so 1/5km per minute. if you want rather the mins per kilometer you have 25 mins per 5 kilometers equals 5 mins per kilometer. depends on the rate you want
Answer:
<h2>Principal</h2>
Step-by-step explanation:
In Business, the formula for calculating simple interest on an amount of money saved is expressed using the formula below.
Simple Interest = Principal * Rate * Time/100
From the question, the parameters given are the time which is 5 years and the rate at 3.75%. There is no information on the principal and <u>before we can calculate the simple interest that Li will earn, the her principal must be made known</u>. Principal is like the amount she initially saved in her account.
<em>Hence, </em><em>the additional information that she needs</em><em> to find the simple interest </em><em>is her principal.</em>

Answer:
x = -12
Step-by-step explanation:
Remember that ax + bx = (a+b)x
-10x + 9x = 12
Add -10x and 9x together
(-10 + 9)x = 12
-x = 12 (-1x is written as -x, just as 1x is written as x)
÷ -1 both sides
x = -12
I hope this helps. Happy studying. :)
Answer:
3 cm by 10 cm
Step-by-step explanation:
Assuming the new dimensions are integers, we can look at the factors of 98 to see what they might be.
98 = 1·98 = 2·49 = 7·14
The latter two factors differ by 7, so are the dimensions after 4 is added. The original dimensions are ...
7 - 4 = 3 . . . . cm
14 -4 = 10 . . . . cm
The dimensions of the original rectangle are 3 cm by 10 cm.
The formula for the volume of a cone is V=(1/3)πr^2h.
To find r (radius) divide the diameter by 2, giving you 2.5 cm.
Plug in the numbers now !
V=(1/3)(3.14)(2.5^2)(9)
V=(1/3)(3.14)(6.25)(9)
V=(1/3)(176.625)
V=58.875
Therefore, the volume of the cone is about 59cm^3 :)
