Answer:
Miguel start to swim when Ario has traveled 4.4 m.
Step-by-step explanation:
The total lenght of the pool is 25.
Since both of them standing 3 m from one side of the pool, then, the total distance both need to cover is 
m= 22 m.
Assume that the distance traveled by Ario before Miguel start to swin is 
. That means, the remaining distance to Ario (to cover the total size of the pool) is 
.
Then, in acoordance to the problem, the ratio between these two distances must be equal to 1/4.
That is,
.
So, we need to obtain from this equation. We must note that 
, otherwise we have a zero in the denominator.
So, we rearrange the equation,
(Multiplying both sides of equation by (
).
Then, 
.
Therefore, 
m.
Answer:
square root 162
Step-by-step explanation:
I simply divided by 100 and moved the decimal two places to the left.
A graphing calculator shows the rocks are at the same height 1.5 seconds after they are released.
That height is 3.975 meters.
_____
f(x) = g(x)
-4.9x^2 +15 = -4.9x^2 +10x
15 = 10x . . . . . . . . . . . . . . . . . . add 4.9x^2
1.5 = x . . . . . . . . . . . . . . . . . . . divide by 10
f(1.5) = -4.9*2.25 +15 = 3.975
Answer:
B ) 0.25 + 0.75 + 0.76 + 0.24
Step-by-step explanation:
<u>commutative law of addition:-</u>
According to the commutative property of addition,changing the order of the numbers.we are adding doesn't change the sum.
let a,b,c+d are two numbers
The commutative property condition in addition a+b+c+d = a+c+b+d
Given expression 0.25+0.76+0.75+0.24 = 0.25 + 0.75 + 0.76 + 0.24
conclusion:- Answer B.
