What is the relationship between the 6s in the number 660,472

scoundrel [369]

Answer:
The first 6 is 10 times greater than the second one

Explanation:
The given number is 660,472
This number can be rewritten as:
660,472 = 600,000 + 60,000 + 400 + 70 + 2

Now, comparing this to the place-value chart shown in the attached image, we would find that:
The first 6 represents the hundred thousands of the number
The second 6 represents the ten thousands of the number
The 0 represents the thousands of the number
The 4 represents the hundreds of the number
The 7 represents the tens of the number
The 2 represents the ones of the number

Now, we are comparing the values of the 6s:
The first 6 represents the hundred thousands of the number
The second 6 represents the ten thousands of the number
This means that:
The first 6 is 10 times greater than the second one

Hope this helps :)

Tessa is cooking steak for her family. She wants to be sure the steak has an internal temperature of at least 160 degrees Fahren

Over [174]

Answer:

Population : all the steaks Tessa can cook

Parameter : minimum internal temperature of 160 degrees Fahrenheit

Sample : two random thermometer readings

Statistic : minimum sample reading of 165 degrees Fahrenheit

Step-by-step explanation:

Let's recall the definitions of these statistical concepts and match it with the information that were provided to us:

Populations can be the complete set of all similar items that exist, in our case, all the steaks that Tessa can cook.
Parameter is is a value that describes a characteristic of an entire population, such as the minimum temperature of the steaks Tessa is cooking in Fahrenheit degrees.
Sample is a subset of the population, in our case, the two random readings of the thermometer Tessa did.
Statistic is a characteristic of a sample, for our problem, it's the minimum reading of 165 degrees Fahrenheit.

What is the solution to the system of linear equations below? 2/5x−y=6 −2x+5y=−30 Select one: A. (-13, 14) B. (-5, -8) C. no sol

tester [92]

Answer:

D. Infinitely many solutions

Step-by-step explanation:

$-\frac{2}{5}x-y=6 | -2x+5y=-30$

1.Since neither equation contains an isolated. However, we can isolate -y in the first equation by adding $\frac{2}{5}x$ to both sides.

Like this: $\frac{2}{5}x-\frac{2}{5}x-y=6-\frac{2}{5}x$

ending up with $y=6-\frac{2}{5}x$

2.Now, we can change y to a positive y. By doing so, we divide -y by the entire equation.

Like this $\frac{-y=6-\frac{2}{5}x }{-y}$

Ending with $y=-6+\frac{2}{5}x$

3.Now, we can plug the expression $-6+\frac{2}{5}x$ into the second equation as a substitute for y, and solve for x. Then, we can use x to calculate y.

Like this $-2x+5(-6+\frac{2}{5}x)=-30\\ -2x-30+2x=-30\\$

4. Since -2x+2x would cancel out and leave -30=-30. This is true because we know -30 equals -30 with no variable in sight.
