Answer:

  B  -11 4/15

Step-by-step explanation:

  -7 3/5 -3 2/3 = -(7 3/5 +3 2/3)

  = -((7 +3) +(3/5 +2/3)) = -(10 +9/15 +10/15)*

  = -(10 +19/15) = -(10 +1 4/15)

  = -11 4/15

which can be written as 3 x 100 kilometers. What is n?

Answers

Answer:

D. 14.

Step-by-step explanation:

As we know, 10 to the second power is 100, to the third power is 1000, and so on. These powers add a zero to the number. Since PEMDAS tells us to do exponents before multiplication, we need to find what power of 10 gives us 100,000,000,000,000. Let's count all the zeros. There are 14 zeroes. This means our answer is D. 14. Let's check, though. 10 to the 14th power is 100,000,000,000,000, and that times 3 is 300,000,000,000,000. That means our answer is correct, it is in fact, D. I hope this helps!

Edit: I changed the answer from 13 to 14 because I realized that 13 is incorrect.

Step-by-step explanation:

a triangles angles equal 180 so 180-10-19-90 = 61

Answer:

-9

Step-by-step explanation:

Since the opposite angles of both sides are congruent we know that the sides must be congruent also. Therefore, to solve for x we can set them equal to each other.

So the equation will be x+19=10, to solve we must isolate the variable.

First, subtract 19 from both sides

x+19-19=10-19

Then, simplify

x=-9

General Formulas and Concepts:

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Algebra I

Combining Like Terms

Step-by-step explanation:

Step 1: Define Equation

2(x + 2x) = 36

Step 2: Solve for x

Combine like terms:                    2(3x) = 36Divide both sides by 2:               3x = 18Divide both sides by 3:               x = 6

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Substitute in x:                   2(6 + 2(6)) = 36Multiply:                              2(6 + 12) = 36Add:                                    2(18) = 36Multiply:                              36 = 36

Here we see that 36 does indeed equal 36.

∴ x = 6 is the solution to the equation.

Answer :

2(x+2x)=36

2x + 4x =36

6x =36 is the answer

Answers

C is the correct answer

The cross-sectional area of the shaft is 314 mm²

The outside diameter (d₂) = 6 cm = 60 mm

The inside diameter (d₁) = 4 cm = 40 mm

The cross sectional area of the shaft (A) is given by:

A = π(d₂ - d₁)²/4

Substituting values:

A = π(60 - 40)²/4

Simplifying the equation:

A = 314 mm²

The cross-sectional area of the shaft is 314 mm²

You stand 50 feet from a monument. The angle of depression from the top of the monument to your feet is 64 degrees. Approximately how tall is the monument

Answers

Answer:

The monument is approximately 86.6 feet tall

Step-by-step explanation:

The given monument parameters are;

The distance of the person from the monument = 50 feet

The angle of depression from the top of the monument to the person's feet = 64°

Given that the angle of elevation to the top of the monument from the person's feet = The angle of depression from the top of the monument to the person's feet, we have;

tan(Angle of depression) = tan(Angle of elevation) = (The height of the monument)/(The distance from the monument)

∴ The height of the monument = tan(Angle of depression) × The distance from the monument

Substituting the known values, gives;

The height of the monument = tan(60°) × 50 ≈ 86.6

The height of the monument ≈ 86.6 feet.
