Convert 2 km into cm
1 km = 100,000 cm
2 km = 200,000 cm
therefore 9,000 cm is greater
She has a difference of $2.75, she may have subtracted something wrong while balancing out the check book.
Hello! The answer to your question would be as followed:
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
-79-(7*w+3*(4*w-1)=0
-79 - (7w + 3 • (4w - 1)) = 0
Pulling out like terms :
Pull out like factors :
-19w - 76 = -19 • (w + 4)
-19 • (w + 4) = 0
Equations which are never true :
Solve : -19 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
Solve : w+4 = 0
Subtract 4 from both sides of the equation :
w = -4
w = -4
A wall is in the shape of a trapezoid and it can be divided into a rectangle and a triangle. A triangle is with angles 45°- 45° - 90°. The hypotenuse of that triangle is 13√2 ft.Using the 45° - 45° - 90° theorem, sides of that triangle are in the proportion:x : x : x√2, and since that x√2 = 13√2 ( hypotenuse ), x = 13.Therefore h = 13 ft.We can check it: c² = 13² + 13²,c² = 169 + 169c² = 338c = √ 338 = 13√2Answer: h = 13 ft
Answer:
Step-by-step explanation:
Let's begin with the mass definition in terms of density.
Now, we know the limits of the integrals of x and y, and also know that ρ = ky², so we will have:
Let's solve this integral:
So the mass will be:
Now we need to find the x-coordinate of the center of mass.
Now we need to find the y-coordinate of the center of mass.
Therefore the center of mass is:
I hope it helps you!
