If each stack of coins has the same height, which stack of coins has the greatest volume? A) the uniform stack B) the irregular
Kruka [31]

Answer:

The correct option is D

Step-by-step explanation:

The correct option is D.

They both have the same height, assuming that each coin has same volume, then how can coins in 1 stack have different volume than coins in another stack no matter how you stack them.

Like two cylinders with same base area and height have same volume. Like wise rectangle and parallelogram with same base and same perpendicular height having same area....

Can so.eone explain to me by what bisecting intervals are?​
Tasya [4]

When you bisect something, you cut it into two equally sized pieces. (from Latin: "bi" = two, "sect" = cut)

Bisecting an interval creates two smaller intervals each with half the length of the original interval. Some examples:

• bisecting [0, 2] gives the intervals [0, 1] and [1, 2]

• bisecting [-1, 1] gives the intervals [-1, 0] and [0, 1]

• bisecting an arbitrary interval [a,b] gives the intervals \left[a,\frac{a+b}2\right] and \left[\frac{a+b}2,b\right]

Jalil and Victoria are each asked to solve the equation ax – c = bx + d for x. Jalil says it is not possible to isolate x becaus
Iteru [2.4K]
<span>solve the equation ax – c = bx + d for x:

1) Group the x terms together on the left:     ax - bx - c = d

2) Group the constant terms together:          ax - bx = c + d

3) factor out x:                                             x(a - b) = c + d

4) Divide both sides of the equation by (a - b) to obtain a formula for x:
                                                       c+d
</span>           x(a - b) = c + d   =>    x = ---------
                                                       a-b

This shows that the given equation CAN be solved for x, but there is a restriction:  a must NOT equal b, because if a-b = 0, we'd have division by zero (which is not defined).

Where is Victoria's solution?  Please share it if you want to discuss this problem further.  Thank you.

3x + 5y = 30
GrogVix [38]

Answer:

y= - \frac{3x}{5}  + 6

Step-by-step explanation:

The given linear equation is

3x + 5y = 30

To solve for y, we first subtract 3x from both sides to obtain:

5y = 30 - 3x

Divide through by 5

\frac{5y}{5}  =  \frac{30}{5}  -  \frac{3x}{5}

This simplifies to

y= 6-  \frac{3x}{5}

Or

y= - \frac{3x}{5}  + 6
