Katya cut part of the jump rope off to make it shorter. The new length is 8 1/6 feet. The difference between the original length

and the new length is 5/6 foot. The equation x-8 1.6=5/6 can be used to represent this problem, where x is the original length of the rope. What was the original length of the rope?

The original length is x
The new length = 8 1/6 feet = 49/6 feet
The difference between two lengths is 5/6 feet
x - 49/6 = 5/6
x = 5/6 + 49/6 = 54/6 = 9 feet
The original length of the rope is 9 feet

Answer: The original length of the rope is 9 feet.

Step-by-step explanation:

Here, x represents the original length of the rope,

And, the new length of the rope = 8\frac{1}{6}=\frac{49}{6} feet,

The difference between the new length and the old length of the rope

=x-\frac{49}{6}

According to the question,

x-\frac{49}{6}=\frac{5}{6}

x=\frac{5}{6}+\frac{49}{6}

x=\frac{5+49}{6}=\frac{54}{6}=9

Hence, The original length of the rope is 9 feet.

ohaa [14]

Answer:

D. Obtain a cluster sample by randomly selecting 20 counties and visiting every restaurant within those counties.

Step-by-step explanation:

Since this executive wants to minimize cost and expenses he should use a cluster sample of 20 counties and using the selected counties as a representative of the whole. Cluster sampling is a good and useful way of doing market research. It is more economical than other sampling methods and as the executive cannot get information on the whole population, he would be able to get information from the clusters.

Which order pair is a solution to the system of linear equations -4+y=8 and x-5y=17?
andreev551 [17]

Hello!

To find this ordered pair, we solve for x and y and put them together in an ordered pair.

-4+y=8

x-5y=17

Let's solve the first equation for y.

y= 12

Now, let's plug 12 into the second equation for y.

x-5(12)=17

x-60=17

x=77

Therefore, our ordered pair is (77,12)

I hope this helps!

Zach walked his dog for 7/8 hour. They spent 1/2 of the time at the beach. How much time did Zach and his dog spend at the beach
Tresset [83]

Answer: \frac{7}{16}hour

Step-by-step explanation:

You know that the total time was: 7/8 hour

You also know that they spent 1/2 of the time at the beach.

Therefore, to calculate the time  Zach and his dog spend at the beach (which you can call x) , you must multiply both fractions (7/8 and 1/2).

Then, you obtain the following result:

x=\frac{7}{8}hour*\frac{1}{2}\\\\x=\frac{7}{16}hour

Find a ⋅ b. a = 8i + 6j, b = 4i + 5j
frutty [35]
You could rewrite this as double brackets, as you are multiplying together two sets of two terms. It would then look like:
(8i + 6j)(4i + 5j)
and you can expand by multiplying together all of the terms

8i × 4i = 32i²
8i × 5j = 40ij
6j × 4i = 24ij
6j × 5j = 30j²

To get your final answer, you then just need to add together all of the like terms, and get 32i² + 30j² + 64ij

I hope this helps!

The angle whose sine is 0.39581 is
Lorico [155]
The angle whose sine is 0.39581 is 23.31650126° (round it how you want). 
To calculate this, you need to do the inverse sine of 0.39581. 

Inverse sine looks like sin^{-1}, however, it is not the sine of the angle to the power of -1.
