The sum of 7.2 and a number is 10.
First, write an equation to describe the situation.
7.2 + 3 = 10
What is the number?
The number is

Answers

Answer:

7.2 + x = 10

Step-by-step explanation:

I did 7.2 + x = 10 Because there was suspose to be a number in between

that we do not know so you have to put 7.2 + x = 10

Then... For the next question (The same question but asking the number in between) The second Question you do 7.2 - 10 and you get 2.8

The equation to describe the situation when the  sum of 7.2 and a number is 10 is given so it is 7.2 + x = 10.

Calculation of an equation:

Since

The sum of 7.2 and a number is 10.

So here we assume the number be x

So,

7.2 + x = 10

x = 2.8

hence, The equation to describe the situation when the  sum of 7.2 and a number is 10 is given so it is 7.2 + x = 10.

Answers

Find the distance between the points A(10,-9) and B(8,7) round your answer to the nearest hundredth

Answers

Answer:

16.12 units

Step-by-step explanation:

These two points create a right triangle whose diagonal (hypotenuse) represents the desired distance.

Going from B(8, 7) to A(10, -9) involves two steps:  Moving 2 units to the right from B(8, 7) to A(10, -9), and moving 16 steps down from B(8, 7) to A(10, -9).

Thus, the horizontal side of the triangle in question has length 2 units and the vertical side 16 units.

The length of the diagonal (which is the desired distance) is then

|AB| = +√(2^2 + 16^2) = +√(4 + 256) = +√260

To the nearest hundredth, this is |AB| = 16.12 units

What is the measure of angle X, to the
nearest degree?

Answers

Answer:

56 degrees

Step-by-step explanation:

Assuming this is trigonometry, you use the tangent method. Which means in order to find the angle you put the adjacent side of what your finding and the opposite on top of it.

The equation is tan(angle)= 9/6

You multiply both sides by the arch of tangent and get

angle =tan^-1 (9/6)
