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.

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.

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.

The mortgage department of a large bank is interested in the nature of loans of first-time borrowers. This information will be used to tailor their marketing strategy. They believe that 40% of first-time borrowers take out smaller loans than other borrowers. They perform a hypothesis test to determine if the percentage is the same or different from 40%. They sample 100 first-time borrowers and find 53 of these loans are smaller than the other borrowers. For the hypothesis test, they choose a 5% level of significance. What would be the null and alternative hypotheses

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.

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.

A class is playing a **game **where they add or subtract **numbers **to come up with another **target **number.

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.

⇒ 23 + (-23)

**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.

there were 12 cups of cereal in the box, predict about how many raisins should there

be in the box?

**Answer:**

counted 27 raisins. If

there were 12

**Answer:**

this is the answer

**Step-by-step explanation:**

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)

since r is always positive

(ii)

(iii)

we have no restrictions in radial direction.

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)
