In which number is the digit 5 one-tenth as much than it is in the number 25,973?
garik1379 [7]

Let's first look at the number that we are given.25,973. We would read this number as eighty-nine and five hundred forty seven thousandths.

In this number, the 5 is in the tenths place. That is equivalent to 5/10 or five tenths (five divided by ten or 0.5).

The questions asks you to write a number in which the digit "5" is one-tenth the value of the number 5 in 25,973

You are looking for a number that is one-tenth of 0.5. Remember, one-tenth equals 1/10 which equals 0.1.

One-tenth of 0.5 equals 0.1 multiplied by 0.5 which equals 0.05. Hence, the number 5 has to be in the hundredths place to answer the question.

Using the number that we were given (89.547), if you multiply 25,973 by (1/10) you get 8.9547.

In the number 8.9547, the digit 5 is one-tenth the value of the number 5 in 25,973

The answer is 8.9547.

I hope this explanation helps.

Which inequality statement describes the two numbers on a number line? "6 and a number 10 units to the left of 6" A) 10 > 6 B
almond37 [142]

Option D

- 4 < 6   inequality statement describes the two numbers on a number line

<u>Solution:</u>

Given, statement is "6 and a number 10 units to the left of 6"  

We have to find which inequality statement describes the two numbers on a number line?

Now, we know that, as we move towards left on the number line, the value goes decreasing by 1 for every one unit.

So, a number 10 units to the left of 6 will be 6 – 10 = - 4  

So, the two numbers are 6, -4 and we know that, - 4 < 6

Hence, option D is correct.

Help please, asap. thank you

Answer:

KL = 28

YZ = 76

LZ = 38

Step-by-step explanation:

Because J K and L are midpoints, the segment lengths are half of the segments from the XYZ triangle.

Think of it like this: ZLK is just ZXY scaled to half.

From that we get:

KL = YX/2 = 56/2 = 28

YZ = 2*KJ = 2*38 = 76

LZ = YZ/2 = 76/2 = 38
