What is the solution to 7.5d=2.5d

Answers

Answer 1
Answer:

Answer:

d = 0

Step-by-step explanation:

To find the solution to the given equation, we must solve for d in the equation.

7.5d = 2.5d

Subtract 2.5d from both sides.

5d = 0

Divide both sides by 5.

d = 0

So the solution to the equation would be d = 0.

I hope this helps. Happy studying.

Answer 2
Answer:

Final answer:

The provided equation 7.5d=2.5d seems to be flawed as these quantities cannot be equal unless the variable 'd' is zero. Please double-check the equation.

Explanation:

The equation given is 7.5d=2.5d. However, this equation cannot be correct as 7.5d and 2.5d cannot be equal unless the variable 'd' equals zero. It seems that there's a typo or mistake in the provided equation. The solution could not be found as the equation seems to be flawed. Please double-check the equation and make sure the coefficients (the numbers before the 'd') and the variable 'd' are correct.

Answers

James can do 23 to turn it into 0 by adding a negative number 23 or subtracting a number 23. Then the correct options are B and C.

What is Algebra?

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

For #7 Find the measure of each numbered angle in the rectangle?

Answers

Answer:

1= 29

2= 61

3= 90

4= 29

5= 90

Step-by-step explanation:

A rectangle has 4 - 90 degree angles. This means angles 3 and 5 are 90. This means the other angle will be split into two parts that add together to 90. If one is 61 then the other is 29. This is angle 4. This means angle 2 is 61 and angle 1 is 29 because rectangles have parallel sides.

Find the volume of the solid cut from the​ thick-walled cylinder 1 less than or equals x squared plus y squared less than or equals 2 by the cones z equals plus or minus StartRoot 4 x squared plus 4 y squared EndRoot.

Answers

Answer:

4/3(2√(2)  -1)*\pi this is the answer

Step-by-step explanation:

1<= x^2+y^2 <= 2 by the cons z= +- √((x^2 + y^2))

Let suppose

x = r∙cos(θ)

y = r∙cos(θ)

z = z

The differential volume element changes to

dV = dxdydz = r drdθdz

The limits of integration  in cylindrical coordinates are:

The limits of integration  in cylindrical coordinates are:  

(i)

1 \leq  x^2 + y^2\leq  2

1 \leq  r^2 \leq  2

since r is always positive

1 \leq  r \leq √(2)

(ii)

- √((x^2+ y^2))  \leq z \leq +√((x^2+ y^2))

- r \leq  z  \leq  r

(iii)  

0 \leq Theta \leq 2∙π

 we have no restrictions in radial direction.

V = \int\limits^a_b { dV} \,

Remaining derivation has been explained in the atatchment where we get the volume of the cylinder

The volume of the solid cut from the thick-walled cylinder and cones is 4π/3 (2√2 - 1) using cylindrical coordinates.

To determine the volume of the solid cut from the given cylinder and cones, we'll utilize cylindrical coordinates. The cylinder is represented by 1 ≤ r² ≤ 2, or 1 ≤ r ≤ √2, in cylindrical coordinates, where x² + y² = r². Similarly, the cones are represented by z = ±2r. The volume differential in cylindrical coordinates is dV = rdzdrdθ.

Integrating over the appropriate limits, we obtain the volume of the solid:

V = ∫₀²π ∫₁√₂ -2r²r²dzdrθ

Evaluating the integral, we get:

V = 4π/3 (2√2 - 1)
