Distance = speed x time
speed = distance/time
time = distance / speed
400m/36s = 11 1/9 m per second
The answer to 2 is <span>√30/5 or 1.09545
First, you multiply the numerator and denominator by </span>√5.
√6x<span>√5=√30
</span>√5x<span>√5=5 (when a square root of an expression is multiplied by itself, the result is that expression) Therefore, the answer is </span><span>√30/5 or 1.09545
</span>
Answer:
(x + 3) = 9/2
Step-by-step explanation:
Here, we want to write an equation to find the length of the rectangle
Mathematically;
Area of rectangle = length * breadth
15 3/10 = (x + 3) * 3 2/5
(x + 3) = 15 3/10 divided by 3 2/5
(x + 3) = 153/10 * 5/17
(x + 3) = 9/2
To re-phrase this: 50 is a certain percent of 90.
this can be written mathematically as 50=x%*90
let's divide both sides by 10:
5=x%*9
and divide both sides by 9:

which in decimals is approximately 0.56 (but not exactly).
so 0.56=x%
and the x then 56
so 50 is
approximately 56% of 90:
exactly 56%of 90 is 50.4
