Answer:

$96units^2$

Step-by-step explanation:

The total surface area of a cube is given by $6l^2$ .

The first cube has side length $l=6$ units.

This cube has total surface area, $6(6)^2=216units^2$ .

If the second cube is reduced in size by $\frac{2}{3}$ , then the corresponding change in area is $\frac{2^2}{3^2}=\frac{4}{9}$ .

the total surface area of the new cube is $=\frac{4}{9}\times 216$ .

$=96units^2$

How to solve this please help me 2/3×1/2(3/4÷1 2/5)

Damm [24]

Answer:

0.624999999(repeating) so i would round it to 0.625 or 0.63 (both work and are rounded, its really up to wherever your teacher wants you to round it to if they want you to round it)

Step-by-step explanation:

2/3 x 1/2 (3/4 ÷ 2/5)=

simplify the parentheses (3/4 ÷ 2/5) to 1.875

2/3 x 1/2 x 1.875=

simplify 2/3 x 1/2 to 0.333333(repeating)

0.3333333333 x 1.875 = 0.6249999999(repeating)

round it to 0.625 or 0.63 (which ever one your teacher wants you to round it to)

The area of a rectangular knitted blanket is 10x squared minus 11x minus 6. What are the possible dimensions of the blanket? Us

Dmitrij [34]

Answer:

Dimensions of rectangle are $(5x+2)\:and\: (2x-3)\\$

Step-by-step explanation:

Area of rectangular knitted blanket = $10x^2-11x-6$

We need to find the dimensions of blanket.

If we need to find the dimensions, we need to find the factors of area.

Factoring: $10x^2-11x-6$

We will break the middle them -11x

Adding 4x-15x we get -11x

Multiplying 4x and -15x we get -60x^2 (Product of -6 and 10x^2)

Now, finding factors

$10x^2-11x-6\\10x^2+4x-15x-6\\2x(5+2)-3(5x+2)\\(5x+2)(2x-3)\\$

So, factors of $10x^2-11x-6\\$ are $(5x+2)(2x-3)\\$

So, dimensions of rectangle are $(5x+2)\:and\: (2x-3)\\$
