can you predict the outcome of multiplying 750 by 0.1 without calculating

Answers

Answer 1

Answer:

750 × 1/10  = 750/10 = 75

Step-by-step explanation:

The best way to really predict the outcome of multiplying 750 by 0.1 without calculator is firstly, converting the decimal to a fraction to easily do the multiplication in your head.

Since one of the multiplicand is a decimal the products will be much complicated therefore, to convert the decimal number 0.1 to a fraction number we shift the point to the right hand side which simply translate to 1/10.  The trick here is the number of times we shift the point will determine the number of zeros the denominator will possess.  Assuming we have 0.12 as the decimal, it is required we shift the point twice and the resulting value we become 12/100. If the decimal is 0.123 it is required we shift the point 3 times , the resulting value will be 123/1000. Not the number of times we shift the point will determine the number of zero's of the denominator.

Finally, the 2 multiplicands are now 750 and  1/10 which is more easier to manipulate in our head.  

750 × 1/10  = 750/10 = 75( you just cancel the zeros)

Step-by-step explanation:

note that i² = - 1

Thus

[tex]i^{8}[/tex]

= i² × i² × i² × i²

= - 1 × - 1 × - 1 × - 1

= 1 × 1

= 1

The value of complex number is 1. Therefore, the option B is the correct answer.

What is the complex number?

A complex number is the sum of a real number and an imaginary number. A complex number is of the form a + ib and is usually represented by z.

The given complex number is i⁸.

We know that, i²=-1

Now, i⁸ can be written as i²×i²×i²×i²

= -1×(-1)×(-1)×(-1)

= 1

Therefore, the option B is the correct answer.

Step-by-step explanation: To solve for c in this inequality, your goal is the same as it would be you were solving an equation, to get c by itself on one side of the inequality.

Since 2 is being added to c, subtract

2 from both sides of the inequality.

On the left, the +2 and -2 cancel out

and on the right, -1 - 2 is -3.

What is the length of the missing leg

Answers

Answer:

12

Step-by-step explanation:

Using the pythagorean theorem, we know that a^2+ b^2=c^2

In our case, we know b, which is 5 and c which is 13.

If we plug that into the equation, we get a^2+ 5^2 = 13^2

Next, we simplify the equation. a^2 + 25 = 169

Then we subtract 25 from 169. 169 - 25 = 144.

Lastly, we do the square root of 144 and we get 12 which is the missing side.

Answer: 12 miles

Step-by-step explanation:

Use Pythagorean Theorem to find the missing side.

a^2 + 5^2 = 13^2

a^2 + 25 = 169

subtract 25 from both sides

a^2 = 144

take the square root of both sides

a = 12

The following box plot shows points awarded to dance teams that competed at a recent competition:
Which dot plot best represents the box plot data?

Answers

Answer:

C

Step-by-step explanation:

In the box plot we can see that

minimum points awarded: 0maximum points awarded: 100

then, options B and D are incorrect

The median in the box plot is 70. In option A, the median is 95, and in option C, the median is 70.

In option C, also, Q1 is located at 50 (like in the box plot), and Q3 is located at 95 (like in the box plot)

The dot plot that best represents the box plot data is: C.

The minimum, maximum, and median value of a a data set can easily be determined when the data points are plotted on a box plot or dot plot.

Thus, for the box plot, we have the following:

Minimum = 0Maximum = 100Median = 70

Find the dot plot that has the above values as same with the given box plot:

The dot plot in option C has minimum of 0, maximum of 100, and median of 70, therefore, the dot plot that best represents the box plot data is: C.
