Answer:

10

Step-by-step explanation:

Given expression is |8-6 i|.

|8-6 i| is a complex expression.

The value of<em> i </em>is –1.

By definition of absolute value, |a+b i|=\sqrt{a^{2}+b^{2}}

Now, substitute |8-6 i| in the above formula.  

\Rightarrow|8-6 i|=\sqrt{8^{2}+(-6)^{2}}  (since <em>i </em>= –1)

                  =\sqrt{64+36}  (since 8^{2}=64 and                    –6^{2}=36)

                  =\sqrt{100}  (Square root of 100 is 10)

                  = 10

Hence, the value of the expression  |8-6 i| is 10.

1) Working alone, Beth can tar a roof in 151
Pachacha [2.7K]

Answer:

A) 7.24 hours

Step-by-step explanation:

The together rate is the sum of each separate rate.

In this problem:

Beth's rate is 1/15(suppose there was a small typing mistake there, with 151 none of the options are correct).

Mike's rate is 1/14

The together rate is 1/x

Then

We want to find x.

\frac{1}{15} + \frac{1}{14} = \frac{1}{x}

15*14 = 210. So

\frac{14 + 15}{210} = \frac{1}{x}

\frac{29}{210} = \frac{1}{x}

Cross multiplication

29x = 210

x = \frac{210}{29}

x = 7.24

So the correct answer is:

A) 7.24 hours

At a museum cafe you can get a pre-made boxed lunch with a sandwich, fruit, and drink for only . The sandwiches are made with ei
slamgirl [31]

Answer:

1/8 or 0.125

Step-by-step explanation:

So, I started solving this problem by writing all the possible options, then pairing them each up with a fruit and drink..

...But when I read the question again, I noticed I forgot to leave out the fruit, as this question states that you're trying to retrieve "a turkey sandwich and a bottle of water.."

Well, oof.

Despite that, I'm still giving this answer as if it never left out the fruit. So, let's see what we need to do.

To find all the possible lunch options, I started out by writing down one of our meats, Turkey. As per requested, I made every possible turkey combination that included a fruit and drink, which gave me this:

  • Turkey, apple and water
  • Turkey, orange and water
  • Turkey, orange and juice
  • Turkey, apple and juice

Same for the ham:

  • Ham, apple and water
  • Ham, apple and juice
  • Ham, orange and juice
  • Ham, orange and water

Putting these together, this gives up 8 different lunchbox combinations. If we're trying to get one and we randomly select it, then we have a 1/8 chance of grabbing the turkey sandwich and a bottle of water....

..and a fruit.

Hope this helped!

If you need me to show my work, just comment me and I will attach a screenshot!
