Nico is trying to divide a 6 by 4 inches of rectangular cartoon sheet into pieces of squares. Given that he used up all of the m

ELEN [110]

Answer:

Minimum of 6 squares.

Step-by-step explanation:

The dimension of the rectangular carton = 6 by 4 inches.

The area of the carton = length x width

= 6 x 4

= 24 square inches

Assume that we have a square of side length 2 inches, then;

area of the square = length x length

= 2 x 2

= 4 square inches

So that since all materials is to be used,

the minimum number of squares that it can produce = $\frac{24}{4}$

= 6

5x−2.5+6x−3= ___ (2x−1)

LiRa [457]

Answer:

5.5

Step-by-step explanation:

So, this is a simple factoring problem. The answer is 5.5(2x-1). So, heres how we get that answer.

So, factoring is basically breaking down the problem into smaller parts. So once we simplify the problem, we can factor it.

Simplify by combining like terms: 5x+6x= 11x and -2.5-3=-5.5

Now we have 11-5.5=?

so, we need to have (2x-1) in our answer because the problem asks for that in the answer.

We need to find a number that satisfies the equation and answer

so, 5.5(2x) is 11x, and 5.5(-1) is 5.5.

5.5 satisfies the equation, therefore is the answer

Each side of an equilateral triangle measures 30cm. Find the length of an altitude, a , of the triangle?

Archy [21]

Answer:

$X=25.98cm$

Step-by-step explanation:

From the question we are told that:

Length of each side $l=30cm$

Let the triangle be divide by two form a right angle triangle with base angles as $90 \textdegree$ (angle of perpendicularity) and $60 \textdegree$ (angle on each vertices of an equilateral triangle)

Generally the equation for the Altitude X is mathematically given by

Trigonometric Rule

$X=30sin60$

$X=15\sqrt{3}$

$X=25.98cm$
