Answer 1

Answer:

The solution of the given multiplication expression is 13.5424 and the sign is positive.

What is multiplication?

Multiplication is the process of determining the product of two or more numbers in mathematics. A product, or an expression that specifies factors to be multiplied, is what happens when you multiply two numbers in mathematics.

The given multiplication expression will be solved as,

E =(-1.15) x 3.2 x (-1.15) x 3.2

E = -1.15 x 3.2 x (-1.15) x 3.2

E = -1.15 x 3.2 x -1.15 x 3.2

E = -3.68 x -1.15 x 3.2

E= 4.232 x 3.2

E= 13.5424

Therefore, the solution of the given multiplication expression is 13.5424 and the sign is positive.

Answer 2

Answer:

Answer:

13.5424

Step-by-step explanation:

(-1.15)*3.2*(-1.15)*3.2

-1.15*3.2*(-1.15)*3.2

-1.15*3.2*-1.15*3.2

-3.68*-1.15*3.2

4.232*3.2

13.5424

Do you see that little square in one corner of the triangle ? That tells you
that the angle there is 90 degrees, and THAT tells you that the triangle is
a RIGHT triangle. This is a very helpful piece of information, because there's
a rule about the sides of a right triangle that isn't true for any other kind of triangle. The rule is:

   (the longest side)² = (one of the other sides)² plus (the third side)²

Also, the longest side is always the one that doesn't touch the 90-degree angle.

In this triangle in the picture,

-- the longest side is 'A' ... it's 13 .
-- one of the other sides is ' b ' ... it's 12 .
-- the third side is ' C ' ... the one you have to find.

Using the formula up above, you know that

   (13)² = (12)² + C²

Before you go to work on it, subtract (12)² from each side of this equation,
just to make it a little easier, and then you have

   C² = (13)² minus (12)²

And right there is how to figure out the length of ' C '.

I'll give you even more information to help you, and then it's up to you
to finish it and get the answer. Here it is:

   (13)² = 169

   (12)² = 144

Now you have everything you need. Go to it !

To get the answer we can use Pythagorean theorem.
$12^2+c^2=13^2 \n 144+c^2=169$ /-144
$c^2=25 \n c=5$ - its the answer

You backpacked for a distance of 15.75 miles today. If you backpacked at an average speed of 1.26 miles per hour, how many hours did you spend backpacking today

Answers

It would be 12.5. you would divide 15.75 by 1.26

Hi there! First, speed=Distance/time, and the time=distance/speed. The time spent for back packing was 15.75/1.26=12.5 hours. Therefore, the answer is 12.5 hours.
