60 in scientific notation

Answers

6 x 10 to the first power

Answer:

I think the answer would be 6.0x10¹

If 60 was in scientific notation it would look like 6.0 because there is only one zero and we would need to move the decimal one place to the right. So we multiply 10¹ so we can move that decimal to the right to make 60.

How does 8/10= 80/100

Answers

When dealing with fractions, it is important to realize that it is the quotient of the numerator and the denominator that matters. 8/10 is 0.8, and 80/100 is 0.8. if you multiply the 8/10 x 10/10, it becomes 80/100. likewise, if you reduce 80/100, it becomes 8/10.

Answer: well, they are both equal because, in this case, you take 8/10, and multiply both sides by 10. that would get you 80/100

Step-by-step explanation:

A pair of shoes that originally sold at $30 is now being offered at a 25% discount.
What is its present price?

Answers

Answer:

$22.5

Step-by-step explanation:

You will pay $22.5 for a item with original price of $30 when discounted 25%.

Answer:

Refer to explanation

Step-by-step explanation:

The screenshot you put is the correct answer, here's another method to get the same answer:

Find what 25% is.

100% = 30

1% = 30 ÷ 100 = 0.30

25% = 0.30 x 25 = 7.50

Find the price after the 25% discount.

100 - 25 = 75

75% = 30 - 7.50 = 22.50 or 0.30 x 75 = 22.50 (Both solutions give the same answer)

Can you find four examples that are true or a counterexample for the following statement?For every integer n, the value of n^2 + 1 is odd

Answers

Counterexample: n= 1
n²+1 = 2

Solving the expression, it is found a counterexample that when [tex]n = 1[/tex], [tex]n^2 + 1 = 2[/tex] is even.

----------------------

The expression given is:

[tex]E(n) = n^2 + 1[/tex]

We want to test for every integer n, that E(n) is odd.

----------------------

For n = 0:

[tex]E(0) = 0^2 + 1 = 0 + 1 = 1[/tex]

Odd number.

----------------------

For n = 1:

[tex]E(1) = 1^2 + 1 = 1 + 1 = 2[/tex]

Even, thus, this is the counterexample.

3. A manufacturing process produces integrated circuit chips. Over the long run, the fraction of bad chips produced by the process is 20%.

Answers

Answer:

0.812 = 81.2% probability that a randomly chosen chip will pass the test

Step-by-step explanation:

Over the long run, the fraction of bad chips produced by the process is 20%.

So 100 - 20 = 80% are good.

All good chips pass the test, while 6% of the bad chips(20%) also pass.

a) (4 points) What is the probability that a randomly chosen chip will pass the test

[tex]p = 0.8 + 0.06*0.2 = 0.812[/tex]

The time of a pendulum varies as the square root of its length. If the length if a pendulum which beats 15seconds is 9cm, find the length that beats 80seconds and the time of a pendulum with length 36cm

Answers

Answer:

length= 3.7 ft.

Step-by-step explanation:

T= (square root of length) * k

1.8 seconds = (square root of 3) * k

k= 1.8 seconds / (square root of 3)

a.) T= (square root of 11) k

substituting k:

T=(square root of 11) * 1.8 seconds / (square of 3)

T= 3.4 seconds

b.) 2 seconds = (square root of length) k

substituting k:

2 seconds =(square root of length) 1.8 seconds / (square root of 3)

Divide the equation by 1.8 seconds / (square root of 3):

2 seconds / [1.8 seconds / (square root of 3)] = (square root of length)

10(square root of 3) / 9 = (square root of length)

square both sides:

100/7 ft= length

length= 3.7 ft.
