Answer:

\left \{ {{h=15s} \atop {t=7s+200}} \right.

Step-by-step explanation:

Let h be equal to the number of meters the hare travels.

Let t be equal to the number of meters the tortoise travels.

Let s be equal to the number of seconds that pass.

The hare travels at a speed of 15 meters per second, which means 15s represents the number of meters the hare travels depending on the number of seconds that pass.

h=15s

The tortoise travels at a speed of 7 meters per second, which means 7s represents the number of meters the tortoise travels depending on the number of seconds that pass.

t=7s

However, because the tortoise got a 200-meter head start, we need to add 200 meters to our equation.

t=7s+200

Here is our system of equations:

\left \{ {{h=15s} \atop {t=7s+200}} \right.

I hope this helps!

Rob peeled 125 oranges in 5 hours. At that rate, how many oranges<br> would he peel in 12 minutes?
marin [14]

Answer:

\boxed {\tt 5 \ oranges}

Step-by-step explanation:

Let's set up a proportion.

\frac{oranges}{minutes} =\frac{oranges}{minutes}

He can peel 125 oranges in 5 hours. First, let's find the minutes in 5 hours.

There are 60 minutes in 1 hour, so multiply 60 and 5 (60*5=300). There are 300 minutes in 5 hours.

\frac{125 \ oranges}{300 \ minutes}=\frac{oranges}{minutes}

We don't know how many oranges he can peel in 12 minutes. So we say he can peel x oranges in 12 minutes.

\frac{125 \ oranges}{300 \ minutes}=\frac{x \ oranges}{12 \ minutes}

\frac{125 \ }{300 \ }=\frac{x \ }{12 }

Solve for x by isolating it. x is being divided by 12. The inverse of division is multiplication. Multiply both sides of the proportion by 12.

12*\frac{125 \ }{300 \ }=\frac{x \ }{12 \ }*12

12*\frac{125 \ }{300 \ }=x

12*0.416666667=x

5=x

Rob can peel 5 oranges in 12 minutes.

The length of a rectangular field is 6 metres longer than its width. If the area of the field is 72 square metres, What are the
Mnenie [13.5K]

Answer:

The length is 12metres, the width is 6metres

Step-by-step explanation:

Suppose the width is x, the length is x+6

The square is 72. The square of rectangular field is equal to product of length and width.

so x(x+6)=72

x^2+6x-72=0

a=1 b=6 c=-72

D= b^2-4ac= 6*6+288= 36+288= 324

sqrtD= 18

x1= (-b-sqrtD)/2a=(-6-18)/2= -12 (it is negative, but width is only positive. So this root doesn't match)

x2=(-b+sqrtD)/2a= (-6+18)/2= 12/2=6 - the width

The length is 6+6=12
