Answer:

1. 27

2.6

Step-by-step explanation:

1.

remember the priorities of operations :

1. brackets

2. exponents

3. multiplications and divisions

4. (and truly last) additions and subtractions

so,

16 + 14÷2 + 3×5 - 11 =

16 + 7 + 15 - 11 = 23 + 4 = 27

2.

5 coins are tossed at the same time.

each coin has a result (head or tail).

but the observed event is the sum of all tails that show when tossing the 5 coins.

so, the possible outcomes are

0 tails

1 ...

2 ...

3 ...

4 ...

5 tails

so, in total, 6 different possible outcomes.

Brad has two lengths of copper pipe to fit together one has a length of 2 5/12 feet and the other has a length of 3 7 12 ft how
leva [86]
To find the total length of the two copper pipes, we need to add them together.

2 5/12 + 3 7/12 = 5 12/12

Since 12/12 = 1 or a whole, we can simplify this further.

5 12/12 = 6

Hope this helps!

Jasmine can run 4 5/6 miles in 2/3 of an hour. how many miles can she run in one hour
Jlenok [28]

Jasmine can run in one hour is 7.25 miles.

<h3>What is the formula of unitary method?</h3>

The formula of the unitary method is to find the value of a single unit and then multiply the value of a single unit to the number of units to get the necessary value.

Given that,

Jasmine can run 4\frac{5}{6} miles in \frac{2}{3} of an hour.

\frac{2}{3} of an hour = 4\frac{5}{6} miles

                     = \frac{29}{6} miles

By using unitary method we will find the value of an hour.

1 hour = \frac{\frac{29}{6} }{\frac{2}{3} }

          =  \frac{29}{6} × \frac{3}{2}

          = \frac{29}{4}

1 hour  = 7.25 miles

Hence, Jasmine can run in one hour is 7.25 miles.
