8 0

Answer:

S(-7,0) , 2/7

Step-by-step explanation:

To get coordinates of P we can see that

14*(2/7)=4

Now, to get coordinates of S, we have this equation :

x*\frac{2}{7}=-2

Multiply by 7 each side :

2x=-14

x=-7

y=0

Sylvia is hiking from Mineral Creek to Blueberry Hilla distance points of 6 1/5 miles. After hiking 2 2/3 miles , Sylvia stops f
Margarita [4]

Given:

Total distance = 6\dfrac{1}{5} miles

Hiking before lunch = 2\dfrac{2}{3} miles

To find:

How much further does Sylvia have left to hike?

Solution:

Let x be the remaining hiking distance.

We know that,

Total hiking distance = Hiking before lunch + Remaining hiking distance

6\dfrac{1}{5}=2\dfrac{2}{3}+x

\dfrac{(6\times 5)+1}{5}=\dfrac{(2\times 3)+2}{3}+x

\dfrac{30+1}{5}=\dfrac{6+2}{3}+x

\dfrac{31}{5}=\dfrac{8}{3}+x

Isolate variable term.

\dfrac{31}{5}-\dfrac{8}{3}=x

\dfrac{93-40}{15}=x

\dfrac{53}{15}=x

It can be written as

\dfrac{45+8}{15}=x

\dfrac{(3\times 15)+8}{15}=x

3\dfrac{8}{15}=x

So, 3\dfrac{8}{15} miles left to hike.

Therefore, the correct option is C.

Alina [70]

This question is incomplete because it lacks the diagram showing the leaf and stem plots

Find attached to this answer the diagram showing the Stem and leaf plots

Answer:

Only one Zoo has exactly 42 lizards

Step-by-step explanation:

If you check out the attached diagram , you will observe that there is a separation using a vertical line

In the diagram also we have been provided with a key which was explained as :

2|0 = 20 lizards

On the left hand side, we have number ranging from 0 - 6 arranged in a vertical form. On the right hand side we almost have numbers that are arranged in front of each number horizontally

Let me further explain the attached diagram

It is important to note that the numbers arranged vertically on the left are in the units of tens. Hence, using the given key :2l0

1|

2| 0 6 8 8 8

This means , we have 20 lizards in one zoo, 26 lizards in one zoo, 28 lizards in 3 zoos

30 lizards in one zoo, 32 lizards in one zoo, 36 lizards in 2 zoos , 37 lizards in one zoo and 38 lizards in one zoo

4| 1 2 6 6

We have 41 lizards in one zoo, 42 lizards in one zoo, and 46 lizards in two zoos

Based on the explanation given above, we can see that only one Zoo has exactly 42 lizards
