About 0.3 degrees, by estimation.  
The sixty-to-one rule is useful here.  At a distance of 60 units, the angle in degrees and the distance (in units) are about equal for small angles.  
Thirty to two inches is the same as sixty to four inches, about a third of a foot, so the angle must be about a third of a degree.  Rounded it gives 0.3.

erma4kov [3.2K]
Dividing 2 into 4 you would get 2 and dividing it into 9 you would get 4 since you can't divide it into 9 so when you subtract that (9-8) you would get 1 you place a decimal and bring down a zero to get 10 then you would get 5 the answer would be 248.5

Why is subtracting an expression similar to distributing a –1? Use the drop-down menus to explain your answer.
anygoal [31]

Answer:

When subtracting expressions, we are applying the distributive property, where a multiple of an expression in brackets is applied to to each term.

e.g.

a(x + y) = ax + ay

In the case of subtracting an expression, we're doing the same thing, but in the example above, "a" would be equal to -1.

(a + b) - (c + d) ≡ (a + b) + -1(c + d)

And so the negative one is distributed across the terms within the brackets.

Hypotenuse of triangle with sides of 36 and 39
worty [1.4K]

Answer: The hypotenuse is 53 (approximately)

Step-by-step explanation: In this question we shall apply the Pythagoras theorem which states that;

AC^2 = AB^2 + BC^2

Where AC is the hypotenuse and AB and BC are the two other sides. Having been given that the two other sides are 36 and 39 units respectively, the hypotenuse is now,

AC^2 = 36^2 + 39^2

AC^2 = 1296 + 1521

AC^2 = 2817

Add the square root sign to both sides of the equation

AC = 53.0754

Therefore the hypotenuse is approximately 53 units.

What is 13.50 rounded to the nearest tenth
Mkey [24]

Answer:

13.5

Step-by-step explanation:

13.50 is already rounded to the nearest tenth because the 5 is in the tenth place.

13.50 is basically 13.5

If you're looking for 13.5 rounded to the nearest ones or whole number, the answer would be 14 because any number that is five or greater is rounded up while any number that is four or less is rounded down.
