W = -5

Work:
-3+3w=-18 add 3 on both sides to cancel out -3 which is also the first step to isolating w
3w=-15 divide both sides by 3 to isolate w.
W=-5 a negative divided by a positive is a negative.

Hope this helped

In a grid of a backyard, the vertices of the floor of a shed are (20, 80), (50, 60), (50, 20), and (20, 20). The coordinates are

sdas [7]

Answer:

The area of the floor of the shed is 1500 square feet.

Step-by-step explanation:

Given:

The vertices of the floor of a shed are: (20,80), (50,60), (50,20) and (20,20)

Let us plot the given vertices on a graph.

From the graph, it is clear that the given figure is a trapezium with opposite parallel sides being parallel to the y axis. The height of the trapezium is the side that is parallel to x axis.

The area of the trapezium ABCD is given as:

$A=\frac{1}{2}(AB+CD)\times AD$

From the graph, AB = 60 ft, CD = 40 ft, AD = 30 ft

Therefore, the area is given as:

$A=\frac{1}{2}(60+40)\times 30\\A=\frac{1}{2}\times 100\times 30=1500\ ft^2$

Therefore, the area of the floor of the shed is 1500 square feet.

Suppose that you take $350 in currency out of your pocket and deposit it in your checking account. If the required reserve ratio

nika2105 [10]

Answer:

= $3,888.89

Step-by-step explanation:

First, calculate the money multiplier(MM); which is the amount of money that is generated by the banks for each dollar of reserve. In this case, it describes how a deposited amount increases the total supply of money.

Money Multiplier = 1 / reserve ratio

Reserve ratio = 9% or 0.09

Therefore, money multiplier = 1/0.09 = 11.1111

Next, use the reserve ratio to calculate the amount of increase in money supply;

= 11.1111 * $350

= $3,888.89
