Dan's dog walking job pays $15 per hour his job as a car wash attendant pays $400 each week Dan wants to know how many hours he needs to spend walking dogs to earn more than $520 in a week. Which three equalities can model this situation? select all the correct answers.

Dan's Dog Walking Job Pays $15 Per Hour His Job As A Car Wash Attendant Pays $400 Each Week Dan Wants

Answers

Answer 1

Answer:

520<400+15x

15x>120

15x+400>520

Explanation:

Pay of Dan's car wash attendant job =$400 per week

The amount he earns per hour walking dogs = $15

Let the number of hours spent walking dogs in a week = x

Therefore, total earning for walking dogs =$15x

Since he wants to earn more than $520, we have that:

[tex]15x+400>520\text{ (Option F)}[/tex]

We can rewrite this as:

[tex]520<400+15x\text{ (Option B)}[/tex]

If we collect like terms, we have:

[tex]\begin{gathered} 520-400<15x \\ 120<15x \\ \implies15x>120\text{ (Option C)} \end{gathered}[/tex]

So the inequalities are:

0. 520<400+15x

,

1. 15x>120

,

2. 15x+400>520

Hoang has worked as a nurse at Springfield General Hospital for 6 years longer than her friend Bill. Two years ago, she had been at the hospital for twice as long. How long has each been at the hospital?

Answers

Ok let's take the information given and make an equations system with it.

I'm gonna use H for Hoang present working years and B for those of Bill. We know that right now Hoang has worked for 6 years longer than Bill, with this we can create the following equation:

[tex]H=B+6[/tex]

We also have information from two years ago, at that time Hoang's working years doubled Bill's working years. One would feel tempted to write the equation H=2*B but you have to remember that this information is from the past and H and B stand for working years in the present. The correct way to approach this is change H and B by H-2 and B-2 so we consider that this information is from 2 years ago:

[tex]\begin{gathered} (H-2)=2\cdot(B-2) \\ H-2=2B-4 \\ H-2B=-2 \end{gathered}[/tex]

So now we have constructed our equations system:

[tex]\begin{gathered} H=B+6 \\ H-2B=-2 \end{gathered}[/tex]

Let's take the outcome of the first equation and use it in the second one:

[tex]\begin{gathered} H-2B=(B+6)-2B=-2 \\ B-2B+6=-2 \\ -B=-2-6=-8 \\ B=8 \end{gathered}[/tex]

And going back to the first equation:

[tex]H=8+6=14[/tex]

So Hoang has been working at the hospital for 14 years and Bill for 8 years.

The head count changed, and youwent back for an additional 3 avocados and 8pounds of tomatoes, spending another $22.55.What is the price per avocado and pound oftomatoes?

Answers

hello

to solve this question, we need to write an equation expressing the word problem and solve for the price of each item.

let x represent the cost of avocados

let y represent the cost of tomatoes

[tex]\begin{gathered} 5x+3y=13.30\ldots\text{.equation 1} \\ 3x+8y=22.55\ldots\text{.equation 2} \end{gathered}[/tex]

from equation 1, let's make xthe subject of formula

[tex]\begin{gathered} 5x+3y=13.30 \\ 5x=13.30-3y \\ \text{divide both sides by 5 to solve for x} \\ x=\frac{13.30-3y}{5} \\ \text{this is equation 3} \end{gathered}[/tex]

put equation 3 into equation 2

[tex]\begin{gathered} 3x+8y=22.55 \\ 3(\frac{13.30-3y}{5})+8y=22.55 \\ \frac{39.9-9y}{5}+8y=22.55 \\ \text{solve for y} \\ \frac{39.9-9y+40y}{5}=22.55 \\ \frac{39.9+31y}{5}=22.55 \\ 39.9+31y=22.55\times5 \\ 39.9+31y=112.75 \\ 31y=112.75-39.9 \\ 31y=72.85 \\ y=\frac{72.85}{31} \\ y=2.35 \end{gathered}[/tex]

since y = 2.35, let's put that in either equation 1 or 2

from equation 2

3x + 8y = 22.55

put y = 2.35 and solve for x

[tex]\begin{gathered} 3x+8y=22.55 \\ y=2.35 \\ 3x+8(2.35)=22.55 \\ 3x+18.8=22.55 \\ 3x=22.55-18.8 \\ 3x=3.75 \\ x=\frac{3.75}{3} \\ x=1.25 \end{gathered}[/tex]

Step 1:

Figure out the value of cos alpha

We will use the Pythagoras theorem below

[tex]\begin{gathered} \text{hyp}^2=\text{opp}^2+\text{adj}^2 \\ \text{hyp}=41,\text{opp}=40,\text{adj}=x \\ 41^2=40^2+x^2 \\ 1681=1600+x^2 \\ x^2=1681-1600 \\ x^2=81 \\ x=\sqrt[]{81} \\ x=9 \end{gathered}[/tex]

Hence,

[tex]\begin{gathered} \cos \alpha=\frac{\text{adjacent}}{\text{hypotenus}} \\ \cos \alpha=\frac{9}{41} \end{gathered}[/tex]

Step 2:

Figure out the value of cos beta

To figure this out, we will use the Pythagoras theorem below

[tex]\begin{gathered} \text{hyp}^2=\text{opp}^2+\text{adj}^2 \\ \text{hyp}=5,\text{opp}=4,\text{adj}=y \\ 5^2=4^2+y^2 \\ 25=16+y^2 \\ y^2=25-16 \\ y^2=9 \\ y=\sqrt[]{9} \\ y=3 \end{gathered}[/tex]

Hence,

[tex]\begin{gathered} \cos \beta=\frac{\text{adjacent}}{\text{hypotenus}} \\ \cos \beta=-\frac{3}{5}(\cos \text{ is negative on the second quadrant)} \end{gathered}[/tex]

Step 3:

[tex]\cos (\alpha+\beta)=\cos \alpha\cos \beta-\sin \alpha\sin \beta[/tex]

By substituting the values, we will have

[tex]\begin{gathered} \cos (\alpha+\beta)=\cos \alpha\cos \beta-\sin \alpha\sin \beta \\ \cos (\alpha+\beta)=\frac{9}{41}\times-\frac{3}{5}-\frac{40}{41}\times\frac{4}{5} \\ \cos (\alpha+\beta)=-\frac{27}{205}-\frac{160}{205} \\ \cos (\alpha+\beta)=-\frac{187}{205} \end{gathered}[/tex]

In 2000, the population of a town was 46.020. By 2002 wpulation had increased to52,070. Assuming that the towns population is increasing linearly answer the followingquestions.a.What is the population of the town by 2006?

Answers

We know that the population increased linearly, so an adequate model for the population P in year t is:

[tex]P(t)=m\cdot t+b[/tex]

We know that in 2000 the population is 46,020.

In 2002 the population is 52,070.

This are two points of the line that can be written as (2000, 46020) and (2002, 52070).

Then, we can calculate the slope m as:

[tex]m=\frac{P_2-P_1}{t_2-t_1}=\frac{52070-46020}{2002-2000}=\frac{6050}{2}=3025[/tex]

With the slope value we can write the equation in slope-point form:

[tex]\begin{gathered} P-P_0=m(t-t_0) \\ P-46020=3025(t-2000) \\ P=3025(t-2000)+46020 \end{gathered}[/tex]

With the linear equation defined like this (we don't need to calculate the y-intercept), we can calculate the population expected for 2006:

[tex]\begin{gathered} P(2006)=3025(2006-2000)+46020 \\ P(2006)=3025\cdot6+46020 \\ P(2006)=18150+46020 \\ P(20060)=64170 \end{gathered}[/tex]

Answer: the population in 2006 is expected to be 64,170.

O $154.29
o $154.67
O $156.43

Answers

Their total dinner bill including sales tax rate is 8% and  18% tip will be  $156.43 by using the concept of percentages and addition.

What is percent?

A percentage is a number or ratio expressed as a fraction of 100 in mathematics. Although the abbreviations "pct.", "pct.", and occasionally "pc" are also used, the percent sign, "%," is frequently used to indicate it. A percentage is a number without dimensions and without a standard measurement.

What is sales tax?

A sales tax is a fee that is paid to the government when certain goods and services are sold. Typically, laws permit the seller to charge the customer the tax at the time of purchase. Use taxes are typically used to describe taxes on goods and services that consumers pay directly to a governing body.

Here,

$122.75 dollars to be paid without tax and tip,

=8% of $122.75

=$9.82.

=122.75+9.82

=$132.57

=18% of 132.57

=$23.86

=132.57+23.86

=$156.43

Using the addition and percentages concepts, they can calculate their total dinner bill, which is $156.43 after adding the 8% sales tax and 18% gratuity.

If no changes needed enter the original length or state that no changes needed. scalene triangleAB=… BC=…. AC=… equilateral triangleAB = … BC = … AC = …isosceles triangleAB = … BC = … AC = …

Answers

ANSWERS

• They cannot form a triangle

,

• Scalene triangle: ,AB = 7

,

• Equilateral triangle: ,BC = 5, AC = 5

,

• Isosceles triangle: ,AB = 8

EXPLANATION

The sum of the lengths of any two sides of a triangle must be greater than the length of the third side,

[tex]\begin{gathered} 14+8>5\Rightarrow true \\ 14+5>8\Rightarrow true \\ 5+8>14\Rightarrow false \end{gathered}[/tex]

Hence, these side lengths cannot form a triangle.

To form a scalene triangle one of the shortest sides must be larger, for example, AB should be 7, instead of 5. Other combinations are possible as well.

To form an equilateral triangle all sides must have the same length, for example, AB = BC = AC = 5

To form an isosceles triangle, two of the sides must have the same length, while the third side has a different length, for example, AB = 8

To form all three kinds of triangles, the first rule must be valid as well.

The given equation is

[tex]y^2-5y-36=0[/tex]

For solving it we will factorize the number 36 as 9 x 4 which on subtraction gives 5 and on multiplication gives 36.

Then, we have

[tex]\begin{gathered} y^2-(9-4)y-36=0 \\ y^2-9y+4y-36=0 \\ y(y-9)+4(y-9)=0 \\ (y-9)(y+4)=0 \\ y-9=0\text{ and y+4=0} \\ y=p\text{ and y=-4} \end{gathered}[/tex]

Hence, the values of y are 9 and -4.
