During the day, Lola's dog is tied by rope to a tree in the center of her yard. The scale drawing below shows the area that the dog has to run. If the actual length of the rope is 12 1/2 feet, what is the scale used in the drawing?

Answer:

X ____ 0 ______ 1 _______ 2

P(x) __ 1/7 _____ 4/7 _____ 2/7

Step-by-step explanation:

Given that :

Number of red balls = 4

Number of Blue balls = 3

Total number of balls = (4 + 3) = 7

Picking without replacement :

Number of picks = 2

1st pick is red :

Probability = (required outcome / Total possible outcomes)

USing combination formula :

nCr = n! / (n-r)! r!

Total possible outcome :

7C2 = 7! / 5!2! = 7*6 / 2 = 42 / 2 = 21

X = number of red

For red = 0;

P(x =0) = required outcome / Total possible outcomes

P(x = 0)

Required outcome : [4C0 * 3C2)]

P(x = 0) = [(4C0 * 3C2)] / 21 = (1*3)/21 = 3/21 = 1/7

P(x = 1)

Required outcome : [4C1 * 3C1)]

P(x = 1) = [(4C1 * 3C1)] / 21 = (4*3)/21 = 12/21 = 4/7

P(x = 2)

Required outcome : [4C2 * 3C0)]

P(x = 2) = [(4C2 * 3C0)] / 21 = (6*1)/21 = 6/21 = 2/7

Hence ;

X ____ 0 ______ 1 _______ 2

P(x) __ 1/7 _____ 4/7 _____ 2/7

Answer:

5x−y=1

Step-by-step explanation:

An equation is a statement that shows the equality between two expressions.

An equation is said to have no solutions if after solving the equation and the result is a statement like a = b, where a and b are different numbers.

The equation after it is simplified would have the same coefficients and different constant.

Given:

5x−y=7

An equation that will result in a system of equations with no solution will have the same coefficient but different constant.  

Hence 5x−y=1, would give a system of equations with no solution.

Simplifying gives:

7 = 1 (no solution)

Answer:

19,350 dollars is the answer

Step-by-step explanation:

    6 times 216, is 1,290 and 1,290 time 15 is 19,350

Answer:

A) Use compatible number.

For estimate round 216 to 210 and divide by15.

210/15=14 estimate cost

B)Now the exact cost :

Divide 216/15=14.4

When you compare your estimate with exact cost. The answer is reasonable

Answer: The tourist was in the taxi for 23 miles.

Step-by-step explanation:

Step-by-step explanation:

speed =4 miles/hour

distance travelled =31 miles

we have

speed =distance/time

time =31/4hour

for taxi

time =2hours

speed =50mph

distance covered by taxi =?

we have

speed =distance /time

50=distance/2

distance =50×2=100miles

Answer:

X=1 and Y=1 in the first question

Step-by-step explanation:

simply 12X means 12*x, so x=1 and 12*1+3*1=15 question 1

and question 2

2X means 2*X x=8 so 2*8=16 so 16-3 because Y=1 and

16-3=13

Answer:

5 + 1(22-10)

Step-by-step explanation:

3 × 22 = 66

5 + 1(22-10) =5(12) = 60

6 × 7 + 8 × 3 = 42 + 24 = 66

1084 - 1018 = 66

(6 + 5)6 = (11)6 = 66

Answer:

5 + 1(22-10)

Step-by-step explanation:

First we need to solve for 11(7-1). Since the 7 - 1 is in the parenthesis it is what you do first. We know 7 - 1 equals 6. Since we got 6 as our answer for 7 - 1 we would take the 6 and multiply it with the 11 in the equation 11(7-1). If we would multiply 6 x 11 we would have an answer of 66.

Now we need solve each equation to see which one doesn't equal 66.

3 x 22 = 66 therefore it wouldn't be our answer.

5 + 1(22-10), we should always remember that we solve the equation with the parenthesis first. So if we would solve 22 - 10 we would get 12. Next we need to solve 5 + 1 and we should know this equals to 6. Now since we have our answer to both equation we would need to add 12 + 5 If we added those two number we'd get 17. There this would be our ANSWER.

6 x 7 + 8 x 3, we'll need to multiply 6 x 7 and then 8 x 3 after we get our answers to those equations we would need to add them and see if we would get 66 or not. So first I would multiply 6 x 7 and when I multiplied it I got 42. Next we would multiply 8 x 3 and that would equal 24. Now we need to ad 42 + 24. When we add 42 + 24 we get the answer of 66. Therefore this wouldn't be our answer.

1084 - 1018, this one would be easy to solve so we would nee to solve 1,084 - 1,018. If you don't know how to solve that it's okay! We can do it together. So if you write it in a paper or on something you could write it like I'll use a board. You would need to have 1,084 written in the top because that's the biggest number and 1,018 in the bottom because that a smaller number then 1,084. So we would nee to solve the one's place first. We wouldn't be able to solve 4 - 8 so we need to go over to the tens place and take from there now since we took from the 8 it'd become 7 and now the 4 is 14. So we'd do 14 - 8 for the ones place and we have our answer as 6. Now we need to solve the tens place 7 - 1  we know that equals 6 so we need to put 6 under our tens place. Next we go to the hundred place and do 0 - 0 and that's really easy haha it'd equal 0. So under the hundred place we can put 0 or leave it blank I left mines blank. Now finally we would do 1 - 1 and we know that equals 0 as well. So we can put 0 under our thousand place or leave it blank, I left it blank. Therefore this equals 66 so this wouldn't be our answer. Below in the picture I showed my work. :)

(6+5)6, first we do what's in the parenthesis. Which is 6 + 5 that'd equal 11. So since now we have 11 as our answer for 6 + 5 we'd need to do 11 x 6 and that would equal 66. Therefore our answer for this equation would be 66 so it wouldn't be our answer..
