First, find the unit rate, which is, out of how many beans will 1 be nibbled by a rabbit. We can do this by dividing the amount of beans by the amount that had been nibbled:

\sf 100\div 8=12.5

So one out of every 12.5 beans are nibbled on. There are 450 beans in his garden, we can divide our unit rate by this to find out how many he can expect to be damaged:

\sf 450\div 12.5=36

So he can expect 36 beans in his garden to be damaged.

A motor club has estimated that a 325 mile car trip will take 6 1/2 hours. What is the club assuming to be the average speed mil
In-s [12.5K]

<u>Answer: </u>

The average speed that the club is assuming is 50 miles per hour

<u>Solution: </u>

We know that Distance = Speed × Time.

Here it is given that distance is 325 miles and the time to cover 325 miles is 6_{2}^{1} hours which is equal to \frac{13}{2} hours.

Now to find the average speed mile per hour we use the formula

\begin{aligned} \text { Speed } &=\frac{\text { Distance }}{\text { time }} \\ &=\frac{325}{\frac{13}{2}} \\ &=\frac{325 \times 2}{13} \end{aligned}

By cancelling 325 by 13 we get 25

= 25 × 2  

= 50 miles per hour

Thus the average speed that the club is assuming is 50 miles per hour.

aleksandrvk [35]

Answer:

350 points are possible

Step-by-step explanation:

You take 329 divided by 94% or .94 to get 350.

100% of 350 is 350

To double check, 94% of 350 is 329 & 6% of 350 is 21.  329 +21 = 350

Solve the system by the substitution method.
Ghella [55]

Answer:

A) The solution set is (6,-8).

Step-by-step explanation:

3x - y = 26

-3x       - 3x        Subtract 3x from both sides

-y = -3x + 26     Divide both sides by -1

y = 3x - 26

Now plug this into 7x + 8y = -22 to solve for x

7x + 8(3x - 26) = -22        Distribute

7x + 24x - 208 = -22       Combine like terms

31x - 208 = -22

     + 208    + 208            Add 208 to both sides

31x = 186                           Divide both sides by 31

x  = 6

Plug this into y = 3x - 26 to solve for y

y = 3(6) - 26           Multiply

y = 18 - 26              Subtract

y = -8
