Answer:

The correct answer is C. 21x³y

Step-by-step explanation:

Let's simplify the product, this way:

(49x²y)^1/2 * (27x⁶y^3/2)^1/3

Let's recall that x^1/2 = √x and x^1/3 = ∛x

√(49x²y) * ∛(27x⁶y^3/2)

7x √y * 3x² √y

Let's recall that √y * √y = √y² = y

21x³y

The correct answer is C. 21x³y

Find the perimeter of a regular heptagon with consecutive vertices at "A" (-2,-5) and "B" (1,-9)

weqwewe [10]

Answer:

Perimeter is 35 units.

Step-by-step explanation:

A heptagon has 7 equal sides.

Given the length of two consecutive vertices, A(-2-5) and B(1,-9).

We can find the length of AB and multiply by 7.

Recall the distance formula;

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

The length of AB is

$|AB|=\sqrt{(-2-1)^2+(-5--9)^2}$

$|AB|=\sqrt{(-3)^2+(4)^2}$

$\Rightarrow |AB|=\sqrt{9+16}$

$\Rightarrow |AB|=\sqrt{25}$

$\Rightarrow |AB|=5\:units$

Therefore the perimeter is $7\times 5=35\:units$ .

Wouldn’t each section be worth 20%? Saying so 5 goes into 100 20 times.

Answer:

v = 80 mph

Step-by-step explanation:

Given that,

The distance from Wakefield to London is 180 miles.

The train travels this distance in 2 hours 15 minutes.

We need to find the average speed of the train. The average speed of the train is equal to the total distance covered divided by the time taken.

$v=\dfrac{d}{t}\\\\v=\dfrac{180\ miles}{(2+\dfrac{15}{60})\ h}\\\\v=80\ mph$

So, the required average speed of the train is 80 mph.
