The biggest cube has a volume of 64 cubic units, with sides measuring 4 units each.

Answer:

64 unit cubes

Step-by-step explanation:

Given that Elena has 80 unit cubes and needs to construct the largest possible cube, where each unit cube measures 1 unit per side.

To find the largest cube volume close to 80, consider:

1^{3} = 1

2^{3} = 8

3^{3} = 27\\

4^{3} = 64

5^{3} = 125

A cube with 4 units per side has a volume of 64, while one with 5 units per side has a volume of 125.

Since Elena only has 80 cubes, she can build a cube 4 units on each side, yielding 64 cubic units in volume, leaving 16 cubes unused.

A student is deriving the quadratic formula. Her first two steps are shown. Step 1: –c = ax2 + bx Step 2: -c = a[x^2+b/ax] Which
Svet_ta [12734]

The options presented are:

(1) division property of equality

(2) factoring the binomial

(3) completing the square

(4) subtraction property of equality

Response: (2) factoring the binomial

Step 1: -c = ax^2 + bx

Step 2:-c = a[x^2+\frac{b}{a} x]

In step 2, 'a' is extracted from ax^2 + bx. Upon factoring out 'a', we divide all terms by 'a', resulting in a[x^2+\frac{b}{a} x].

Step 2 involves the binomial factorization process.

I helped 3.6 customer per half hour yesterday. so i helped _____ customers in 7.5 hour yesterday
lawyer [12517]

Customers served in 0.5 hours : 3.6   versus   x customers served in 7.5 hours

--------------------   = --------------------

0.5 hours                     7.5 hours



Applying cross multiplication:

3.6 multiplied by 7.5 equals x times 0.5

Dividing both sides by 0.5:

x = (3.6 * 7.5) / 0.5

x = 54

So, you assisted 54 customers in 7.5 hours.

The budget of a university organizations is split evenly among its various committees . if they have a budget of P 60.000 repres
PIT_PIT [12445]

Response:

m(n) = 60000

Amount = 60000/n

Step-by-step breakdown:

Provided

Budget = 60000

Solving part (a) as a function mn

To achieve this, simply substitute m(n) for the budget amount.

This results in;

m(n) = 60000

Solving part (b) for the amount each committee is allocated.

Given that the budget will be evenly split.

Amount = m(n)/n

Replace m(n) with 60000

Amount = 60000/n

PIT_PIT [12445]

Answer: A square that undergoes rotation around its center by 360º aligns with itself at D) 4 distinct angles during the process. Furthermore, a square can be reflected onto itself over B) 4 various lines.

Explanatory breakdown:

A square is a geometric shape characterized by equal-length sides and right angles ( 90^{\circ} ).

Thus, it is capable of being rotated around its center by 360^{\circ}.

It reverts to its original outline at 4 unique rotation angles ( at every 90^{\circ} angle).

The square can also be reflected onto itself across 4 lines (2 through the non-parallel sides and 2 through the corners).
