Force = mass * acceleration
Mass = force / acceleration
Mass = 55.54 / 9.83
Mass = 5.6500508647 kilograms
Mass = 5.65 kilograms

Answer:

4√2 × 4√8 = 64, an integer.

Step-by-step explanation:

a) 4√2 × 4√8

First let's remember that a square root can be rewritten as a 1/2 exponent,

Therefore the expression we have can be rewritten as

$4(2^{1/2} )4(8^{1/2})$

We are going to write all numbers in their prime factor expressions:

*Note: Remember that when we multiply two numbers with the same base but different exponents we sum up the exponents*

*Also, when we elevate one exponent to another exponent, we multiply the exponents*

$4(2^{1/2} )4(8^{1/2})\\=2^2 (2^{1/2})2^2 (2^{3})^{1/2} \\ =2^2 (2^{1/2})2^2 (2^{3/2})\\=2^22^2(2^{1/2}2^{3/2})\\=16(2^{4/2})\\=16(2^2)\\=16(4)\\=64$

Therefore, the expression 4√2 × 4√8 = 64 and therefore is an integer

Arisa [49]

Therefore, the bones were 6612.5 years old at the time they were discovered.

Given that the radioactive element carbon-14 has a half-life of 5750 years, and a scientist determined that the bones from a mastodon had lost 57.5% of their carbon-14, to determine how old were the bones at the time they were discovered, the following calculation must be made:

50 = 5750
100 = 11500
57.5 = X
57.5 x 11500 / 100 = X
6612.5 = X

Therefore, the bones were 6612.5 years old at the time they were discovered.

PLEASE HELP NOBODY EVER ANSWERS MY QUESTIONS Rip van Winkle has fallen asleep for a very long time.

UNO [17]

Answer:

10 millimeters

Step-by-step explanation:

Don't listen to the other answerer who was trolling, I will actually help you. To find how long his beard was when he fell asleep, we need to find the y-intercept. The y-intercept marks how long his beard was right when he fell asleep. From looking at the graph, we can see that the y-intercept is 10. This means his beard was 10 millimeters long when he fell asleep. I hope this helps!

If 5x – 4 = 31, what is the value of x?

Lunna [17]

Answer:

x = 5 $\frac{2}{5}$

Step-by-step explanation:

Hi there!

So, to answer this problem, I'll use the reverse method.

31 - 4 = 27,

So how many times, can 5 go into 27?

The closest factor of 5 to 27 is 25.

5 can go in to 27, 5 times.

Continuing on, there is a 2 left over, so the answer to your question is

x = 5 $\frac{2}{5}$

5 · 5 $\frac{2}{5}$ - 4 = 31

Let me know if I am incorrect and I will attempt to find the right answer for you.
