Answer:

His brother will take 3.5 hours or $3\frac{1}{2}$ hours to mow 21 lawns

Step-by-step explanation:

Given:

His brother mows 6 lawns in an hour.

To find the time his brother takes to mow 21 lawns.

Solution:

We will unitary method to find the time he will take to mow 21 lawns.

If 6 lawns are mowed in 1 hour

So, 1 lawn will me mowed in = $\frac{1}{6}$ hours.

Thus 21 lawns will be mowed in = $\frac{1}{6}\times 21=\frac{21}{6}=3.5$ hours.

Thus, his brother will take 3.5 hours or $3\frac{1}{2}$ hours to mow 21 lawns

–2x(–3x 2 y)(2y) = ? A. 12x 3y 2 B. –3xy2 C. 3xy2 D. –12x 3y 2

Rina8888 [55]

Answer:

Option A - $-2x(-3x^2y)(2y)=12x^3y^2$

Step-by-step explanation:

Given : Expression $-2x(-3x^2y)(2y)$

To find : Solve the expression ?

Solution :

Step 1 - Write the expression

$-2x(-3x^2y)(2y)$

Step 2 - Multiply the first two bracket in multiplication if base are same power get added and apply symbol rule of multiplication $(-)(-)=(+)$

$=(6x^3y)(2y)$

Step 3 - Again multiply the bracket,

$=12x^3y^2$

Therefore, Option A is correct $-2x(-3x^2y)(2y)=12x^3y^2$

Simplify the square root of 32/5

elixir [45]

Remember $\sqrt{ \frac{x}{y} } = \frac{ \sqrt{x} }{ \sqrt{y} }$
and
$\sqrt{ab^2} =b \sqrt{a}$
$\sqrt{ \frac{32}{5} } = \frac{ \sqrt{(4^2)(2)} }{ \sqrt{5} } = \frac{ 4\sqrt{2} }{ \sqrt{5} }$
times whoe thing by $\frac{ \sqrt{5} }{ \sqrt{5} }$
$\frac{4 \sqrt{10} }{5}$
