Answer:

-16

The average of –25, –70, 15, –31, –25, and 40 is -16

To determine the average of the numbers given, we shall find their sum then divide this sum by the number of values;

The sum of the numbers is;

-25-70+15-31-25+40 = -96

Answer: FIRST OPTION.

Step-by-step explanation:

To calculate the average of a set of numbers, we need to add the numbers and divide the sum by the amount of values into that set.

For example, given a set of numbers:

a,b,c,d

The average will be:

average=\frac{a+b+c+d}{4}

Then, the average of the given set of numbers (-25, -70, 15, -31, -25, and 40) is:

average=\frac{-25+(-70)+ 15+(-31)+(-25)+40}{6}\\\\average=\frac{-25-70+ 15-31-25+40}{6}\\\\average=-16

Find the area use 3.14 for pi
Aleonysh [2.5K]

Answer:

15.14 cm^2

Step-by-step explanation:

Area of rectangle = 4cm x 3 cm = 12cm^2

Radius of the circle = 2 cm

Area of 1/4 of a circle = (pi x r^2) / 4

= (3.14 x 4) / 4 = 3.14 cm^2

3.14 cm^2 + 12cm^2 = 15.14 cm^2

Multiply the fractions. Write your answers in simplest form. 1/2 x 2/5
zepelin [54]
First make it that both denominators are the same.
(\frac{1}{2}  \times 5) + ( \frac{2}{5} \times 2) =  \frac{5}{10}  +  \frac{4}{10}
Then add both numerators
\frac{5}{10}  +  \frac{4}{10}  =  \frac{9}{10}
Your final answer should be
\frac{9}{10}
