Use the interactive number line to find -3.2 - 4.

SVEN [57.7K]

Answer:

-7.2

Step-by-step explanation:

Since -3.2 is the first number, this will be the starting point in the number line.

Since we are subtracting, we are going to go 4 units to the left.

-3.2 - 4 = -7.2

Best of Luck!

One leg of an isosceles right triangle measures 5 inches. Rounded to the nearest tenth, what is the approximate length of the

Anestetic [448]

By definition, in an isosceles triangle, the two legs will have congruent lengths.

Since we know that one leg measures 5 inches, we know the other must measure 5 inches as well.

The Pythagorean Theorem states that in a right triangle, a² + b² = c².

Knowing that, we can substitute in our known values.

(5)² + (5)² = c²

From there, we can square our values.

(25) + (25) = c²

And from there, we can add the values together.

(50) = c²

Finally, we can find the square root of both values to give us the length of the hypotenuse.

7.07106781187 = c

And since we're rounding to the nearest tenth, we can rewrite this answer as:

7.1 = c

Therefore, the approximate length of the hypotenuse is 7.1 inches.

Hope this helped! :)

A ship sails from point (1, 2) to point (5, 5), as shown. If each unit represents one mile, how far has the ship sailed?

GrogVix [38]

Hello!

To find how far the ship has sailed, we need to use the distance formula. The distance formula is: $d = \sqrt{(x_{2}-x_{1}) ^{2}+ (y_{2}-y_{1}) ^{2} }$ .

Before using the formula, we need to assign the given points to $(x_{1}, y_{1})$ and $(x_{2},y_{2})$ . The point (1, 2) can be assigned to $(x_{1}, y_{1})$ and (5, 5) can be assigned to $(x_{2},y_{2})$ .
