Answer: $40c m/s$

Solution:

Mouse ran 360 cm straight course race in 9 seconds.

We need to find the rate or speed of mouse

We know the speed formula is distance covered by given time.

$Speed=\frac{Distance}{Time}$

Where,

Distance = 360 cm

Time = 9 seconds

$\therefore$ speed $=\frac{360}{9}$

Speed=40 cm/s

Mouse ran with speed 40 cm/s

Distance covered by by the harvest mouse= 360 cm

Or distance covered by by the harvest mouse= 360 /100= 3.60 m

Time taken to cover the above distance= 9 s

We know,

Speed= distance covered/time taken to cover that distance

Speed= 3.60/9= 0.4 m/s

Therefore, the mouse ran 0.4 m/s fast.

Ryan needs to choose out of the 5 chores for afterschool. If he is equally likely to choose the chores,what is the probability h

Lesechka [4]

Answer: 0.2

Step-by-step explanation:

Number of ways to select r things out of n things = $^nC_r=\dfrac{n!}{r!(n-r)!}$

Then , Total number of ways to select 2 out of 5 chores = $^5C_2=\dfrac{5!}{2!3!}=\dfrac{5\times4\times3!}{2\times3!}=10$

Number of ways to selecting first 2 on list = 2 (either he choose top on the list first then second , or second person first then topper)

Now , the probability he will choose the first 2 on list = $\dfrac{2}{^5C_2}=\dfrac{2}{10}=0.2$

Hence, the probability he will choose the first 2 on list is 0.2.

Answer: OPTION B.

Step-by-step explanation:

Given the following System of equations:

$\left \{ {{3x-5y=19} \atop {x+y=1}} \right.$

You can use the Elimination Method to solve it. The steps are:

1. You can mutliply the second equation by -3.

2. Then you must add the equations.

3. Solve for the variable "y".

Then:

$\left \{ {{3x-5y=19} \atop {-3x-3y=-3}} \right.\\.....................\\-8y=16\\\\y=\frac{16}{-8}\\\\y=-2$

4. Now that you know the value of the variable "y", you must substitute it into any original equation.

5. The final step is to solve for "x" in order to find its value.

Then:

$x+(-2)=1\\\\x=1+2\\\\x=3$

Therefore, the solution is:

$(3,-2)$
