(-7w)^3 = -7w * -7w * -7w = -343w^3
(3t^2)(-5 + 6) = (3t^2)(1) = 3t^2
(6y^2)^3 = 6^3 y^(2 * 3) = 216y^6

In the plane figure, only downward motion (movement leaving you relatively lower than where you were) is allowed. Find the total

bixtya [17]

Plane figures are shapes with straight sides. Considering the movement to be lower than the initial path, there are eleven (11) paths from A to B.

A plane figure is given shape with straight sides. And these sides connect each edge of the figure one to another. Examples are triangles, quadrilaterals, polygons, etc.

A path is a connection or link between two reference points. This could be a footpath or a motorable path or other forms of the path.

Considering the given plane figure in the question, it can be observed that the total number of paths from A to B with respect to the given condition is eleven.

You earn $49 for washing 7 cars. How much do you earn for washing 4 cars?

ICE Princess25 [194]

Answer:

Step-by-step explanation:

We can use the rule of three!

We know we have the following relationship:

$\frac{49}{7} = \frac{x}{4}$

From here, we can solve this like any other equation:

$4(\frac{49}{7}) = x\\x = 28$

Therefore, you would earn $28 after washing 4 cars.

Good luck!

Answer:

27 of the pets are dogs.

Step-by-step explanation:

Real easy way to do this, treat 45 (the total) as 100. So, do 45/100 then multiply the result of that by 60, and you end up with 27.

45/100=0.45

0.45*60=27
