Complete question :

Each year, the Department of Water Works measures the chloride concentration level in the water. The first year, they found the chloride concentration changed by −1 3/5 mg/L . It is estimated that the chloride concentration will change −2 1 /15 mg/L the next year. What is the total change that will likely occur in 2 years?

Answer:

- 3 2/3 mg/L

Step-by-step explanation:

Given that:

Change in concentration during first year = - 1 3/5 mg/L

Estimated change in second year = - 2 1/15 mg/L

Total change in concentration likely to occur over the 2 years:

This will be the sum of the concentration in the first and second year:

[-1 3/5 + (-2 1/15)] mg/L

-1 3/5 - 2 1 /15

-8 / 5 - 31 /15

L. C. M of 5 and 15 = 15

(-24 - 31) / 15

= - 55 / 15

= - 3 10/15

= - 3 2/3 mg/L

Answer: She will need to sell at least ($3,750) of merchandise in order to reach her goal of $475 in one week.

Step-by-step explanation:

It is GIVEN that she earns a weekly salary of $325 and she needs $475.

Subtract $325 from $475 (425-325)=150.

Now we know that she needs $150 to earn on top of her salary to reach her goal of $475.

I used a calculator to plug in (x)0.04=150

I received 3750 as my answer

$3750 times 4%= 150

Answer:

D

Step-by-step explanation:

Here, we want to get the proportion that lies outside the given shown z-scores

Mathematically, that will be:

1 - proportion lying between the two z-scores

The probability lying between the two z-scores can be calculated using the normal distribution table

That will be;

P(-1.25 < x < 0.80)

From the table, this is;

0.68249

So the proportion lying outside will be;

1-0.68249 = 0.31751

This is approximately 0.3175

Answer:

x = 1.727

Step-by-step explanation:

0.2(8x-4) = 0.3(10-2x)

1.6x - 0.8 = 3 - 0.6x

2.2x = 3.8

x = 1.727

Step two:

The compound interest formula is

[tex]A= P(1+r)^t\\\\A= P(1+0.06)^9\\\\A= 300(1+0.06)^9\\\\A= 300(1.06)^9\\\\A= 300*1.689\\\\A=506.7[/tex]

Hello!

[tex]\large\boxed{y = 5(\frac{1}{2})^{x} }[/tex]

Recall that the equation of an exponential graph is:

[tex]y = a(b)^{x}[/tex]

We can see from the graph there is a y-intercept at y = 5. Plugging in 0 for x results in:

[tex]5 = a(b)^{0}\\\\5 = a(1)\\\\a = 5[/tex]

Solve for b by plugging in another point on the graph:

[tex]10 = 5(b)^{-1}\\\\2 = b^{-1}\\\\b = 1/2[/tex]

Write the final equation:

[tex]y = 5(\frac{1}{2})^{x}[/tex]

We have graphed the function f(x) = x + 3 and it's parent function f(x) = x in the image attached below and the parent graph has been transformed 3 units up onto the y axis.

A function is a set of outputs for some set of inputs we can graph function s in x-y co-ordinate.

According to the given question we have to graph a function and it's parent function.

We know a parent function is a function which is free from any transformation so parent function of f(x) = x + 3 is f(x) = x.

f(x) = x implies y = x.

Some points are (-5,-5), (0,0), (2,2).

Graph of these function is attached in the image below.

f(x) = x + 3 here when x = 0 y = 3 implies the whole graph has been transformed 3 units up onto the y axis.

Image of this transformed graph has also been attached.

We can see that the rectangles are congruent meaning they can be mapped onto one another perfectly and therefore 13 and t make up a rectangle the same size and shape as the second one. This means that 13+t will add to 17 since the rectangle they make up is congruent to the second one

Step-by-step explanation:

The solutions to each of the given algebraic expressions when a=2, b = -3, c=4 and d= -5a are as follows;

a) a + 2b = -4

b) bd - 10 = -25

c)  4b + 2a = -8

d) ab + cd = -26

e) cd² + ab = 94

f) d/2 - a = -9/2

g) bc/ad = 6/5

We are given the values a = 2, b = -3, c = 4 and d = -5.

a) a + 2b

Plug in 2 for a and -3 for b to get;

2 + 2(-3) = -4

b) bd - 10

Plug in b = -3 and d = -5 to get;

(-3 * -5) - 10 = -25

c)  4b + 2a

Plug in a = 2, b = -3 to get;

4(-3) + 2(2) = -12 + 4 = -8

d) ab + cd

Plug in a = 2, b = -3, c = 4, d= -5 to get;

(2 * -3) + (4 * -5) = -26

e) cd² + ab

Plug in a = 2, b = -3, c = 4, d= -5 to get;

(4 * (-5)²) + (2 * -3) = 94

f) d/2 - a

Plug in a=2 and d= -5 to get;

(-5/2) - 2 = -9/2

g) bc/ad

Plug in a=2, b = -3, c=4 and d= -5 to get;

(-3 * 4)/(2 * -5) = 12/10 = 6/5

In graphing x is the value on the x axis and y is the values that represent values on y axis.

Given nothing but we are required to tell what x symbolises and y symbolises in graphing.

A graph is basically a common data structure that consists of a finite set of nodes  and a set of edges connecting them.

There are coordinates which are written as (x,y) where x symbolises the values on x axis and y represents the values on y axis.

Suppose the coordinate is (2,3). In this we have to plot a point equal to x=2 and then a point equal to 3.Now take one line from both the points straight and the point where they meet will be (2,3).

Hence in graphing x is the value on the x axis and y is the values that represent values on y axis.

Answer:

Step-by-step explanation:

-3x + 10 = 5x - 8                   Add 8 to both sides

-3x + 10 + 8 = 5x                  Add 3x to both sides

18 = 8x                                  Divide by 8

18/8 = x

x  = 2 3/8

x = 2.375

3 boxes of candy will cost $12 and 4 bags of popcorn will cost $28, adding the two gives us $40. They are only allowed to spend 42 dollars

Step-by-step explanation:

Add the 259 to the initial price:

10,000 + 259 = 10,259

Increase that price by 25%, so multiply by 1.25:

10259 x 1.25 = 12,823.75

The price is then increased by another 10%, multiply by 1.10:

12,823.75 x 1.10 = 14,106.13

List price = $14,106.13
