Answer:

The answer is D.

Step-by-step explanation:

First, we take the info we know. We know that this of multiplication. That means we can rule out A and E.

Now, we need to take the definition of the associative property. The associative property means that you keep the same numbers, variables, and operations, but you switch the grouping. This means that the answer is D. This is because, on both sides of the equation, we keep the same numbers variables and operations. However, on one side we have 4 grouped with r, and on the other, we have 3 grouped with 4. We switched our grouping but kept the expression. This means that our answer is D.

Apply the appropriate mathematical operation to solve this fulcrum problem.

ale4655 [162]

<h2>Hello!</h2>

The answer is:

The second distance ( $distance_{2}$ ) is equal to 7.5 feet.

Since we are given two forces acting at distance, torque will be created. We are given two forces and one distance, so, to calculate the other distance required to balance the system (solve this fulcrum problem), we need to write the following equation:

$Torque_{1}=Torque_{2}$

Where,

$Torque=F*Distance$

We are given,

$Force_{1}=Weight_{1}=150lb\\Force_{2}=Weight_{2}=30lb\\distance_{1}=15ft\\$

So, substituting and calculating, we have:

$Torque_{1}=Torque_{2}$

$Weight_{1}*distance_{1}=Weight_{2}*distance_{2}$

$150lb*15ft=300lb*distance_{2}$

$distance_{2}=\frac{150lb*15ft}{300lb}=7.5ft$

Hence, the second distance ( $distance_{2}$ ) is equal to 7.5 feet.

It's a logical solution since the second force is twice the first force and it means that the second distance must be equal to half the first distance in order to maintain the equilibrium condition.

Have a nice day!

Ava and Jiao each swam a two-lap swimming race. Ava took 31.49 seconds to finish her first lap and 30.03 seconds to finish her s

omeli [17]

Answer:

Jiao's total swimming time is 59.73 seconds

Step-by-step explanation:

i) Ava took 31.49 seconds to finish her first lap.

ii) Ava took 30.03 seconds to finish her second lap.

iii) Therefore Ava took 31.49 + 30.03 = 61.49 seconds to complete her two laps.

iv) Jiao finished her two-lap swimming race 1.76 seconds before Ava.

v) Jiao's total swimming time = 61.49 - 1.76 = 59.73 seconds
