What is the net change in how many bags are on the shelf from

Temka [501]

Answer:

-2

Step-by-step explanation:

The computation of net change from the beginning of Tuesday to the end of Monday is shown below:-

The change at the last of Tuesday

Change = Restock - Sales

= 6 - 5

= 1

Here it indicates that the number of bags is rise by 1

The change at the last of Wednesday

Change = Restock - Sales

= 12 - 8

= 4

Here it indicates that the number of bags is rise by 4

The change at the last of Thursday

Change = Restock - Sales

= 12 - 2

= 10

Here it indicates that the number of bags is rise by 10

The change at the last of Friday

Change = Restock - Sales

= 18 - 19

= -1

Here it indicates that the number of bags is fall by -1

The change at the last of Saturday

Change = Restock - Sales

= 24 - 22

= 2

Here it indicates that the number of bags is rise by 2

The change at the last of Sunday

Change = Restock - Sales

= 0 - 15

= -15

Here it indicates that the number of bags is fall by -15

The change at the last of Monday

Change = Restock - Sales

= 0 - 3

= -3

Here it indicates that the number of bags is fall by -3

According to the given situation, it is equivalent the algebraic sum of every change

So,

Net change = 1 + 4 + 10 + (-1) + 2 + (-15) + (-3)

Using associative property: (1 + 4 + 10 + 2) - (1 + 15 +3)

Simplifying: 17 - 19 = -2

Write an equation of the line that passes through the given point and is perpendicular to the graph of the given equation. Pleas

Anna71 [15]

Answer:

$y = \frac{1}{3}x + 4$

Step-by-step explanation:

First, to figure out the equation of a line you must find the slope then plug in the coordinates.

In order to find the slope of the equation, you know that it is perpendicular to the equation y = -3x + 7.

Perpendicular slopes are basically reciprocals with opposite signs; you flip the number and give it the opposite symbol.

For example, the perpendicular slope of 2 would -1/2, because flipping the fraction 2/1 is 1/2 and the opposite sign of + would be -.

Therefore, the perpendicular slope of -3 would be 1/3, be 3/1 flipped upside down is 1/3 and the opposite sign of - is +.

Then you plug in the slope into the equation of a line along with the coordinate.

A line is y = mx + b

Since you found the slope, m = 1/3

They also give you the coordinate (3,5), meaning when x = 3, the y =5.

You plug everything into the equation to solve for b:

5 = (1/3)(3) + b

b = 5 - (1/3 * 3) = 5 - 1 = 4

Since you have values for m and b, the equation can now be constructed as

y = 1/3x + 4

You launch a water balloon. The function h=-0.08t^2+1.6t+2 models the height h (in feet) of the water balloon after t seconds. W

stellarik [79]

Answer:

The initial height of the balloon is 2 feet.

Step-by-step explanation:

The height of the balloon in feet after t seconds is given by the following equation:

$h(t) = -0.08t^{2} + 1.6t + 2$

What is the initial height of the balloon?

This is h when t = 0, that is, h(0). So

$h(0) = -0.08*0^{2} + 1.6*0 + 2 = 2$

The initial height of the balloon is 2 feet.

What is the base (in inches) of a triangle with an area of 161 square inches and a height of 14 inches?

pantera1 [17]

$\textit{area of a triangle}\\\\ A=\cfrac{1}{2}bh ~~ \begin{cases} b=base\\ h=height\\[-0.5em] \hrulefill\\ h=14\\ A=161 \end{cases}\implies 161=\cfrac{1}{2}b(14) \\\\\\ 161=7b\implies \cfrac{161}{7}=b\implies 23=b$
