Best answer get Brainliest. 50 points. Emerson earns money from walking dogs and answering surveys. He earns $5 a week for each dog he walks and $0.10 for each survey he answers. Last week, Emerson answered 100 surveys and earned $35. Part A: Create an equation that will determine the number of dogs he walked. (3 points) Part B: Solve this equation justifying each step with an algebraic property of equality. (6 points) Part C: How many dogs did Emerson walk last week? (1 point)

[ad_1]

Step-by-step explanation:

5x + 10 = 35 is your equation

5x = 35 – 10    bc u brought the 10 to the other side so its symbol changes

5x = 25         now were going to bring 5 to the other side to do that we have to divide both sides by 5 (same thing like the 10)

5x/5 = 25/5

x = 5

5 dogs

Tracy, a recent college graduate who earned straight as as a history major, is applying for a job as a legal assistant. although she does not have a background in law, she hopes to land the job because of the _____.

[ad_1]

Answer:

The answer to the question: Although she does not have a background in law, she hopes to land the job because of the:___, would be: Screening effect.

Explanation:

The screening effect is a theory that is used by companies and recruiters in order to effectively select and screen the best candidates for a specific position, even if these candidates may not fulfill all the requirements for that position. What the theory does is propose that candidates who have completed a college degree show their capacities, even if these are not specifically related to an expected topic, by simply achieving this goal, and are therefore worthy to be taken into account for selection. In the case of Tracy, she has not just fulfilled the part of the theory of finishing her degree, but she has overachieved by obtaining the best degrees in topics that are related to a job as a legal assistant. The screening effect will allow recruiters to see Tracy´s records and take her into account, even if she has never had any legal experience, due to her achievements in related topics.

127=7 (mod n) means when 127 is divided by n, the division leaves a remainder of 7.

The statement is equivalent to
120=0 (mod n), meaning that n divides 120.

All divisors of 120 will satisfy the statement because 120 divided by a divisor (factor) will leave a remainder of 0.

Factors of 120 are:
n={1,2,3,4,5,6,8,10,12,15,20,24,30,40,60,120}, |n|=16.
You can count how many such values of n there are, and try to check that each one satisfies 127=7 mod n.

The Contribution Margin per unit (CM) can be calculated
from the difference of Selling Price per unit (SP) and Total Expenses per unit
(TE).

 

First, let’s calculate the value of SP:

SP = Sales / Units sold

SP = $1,043,400 / 22,200 units sold

SP = $47

 

Second, calculate all expenses:

Direct materials per unit = $234,948 / 27,970 units
manufactured = $8.4

Direct labor per unit = $131,459 / 27,970 units
manufactured = $4.7

Variable manufacturing overhead per unit = $240,542 / 27,970
units manufactured = $8.6

Variable selling expenses per unit = $113,220 / 22,200
units sold = $5.1

TE = $26.8

 

Therefore the CM is:

CM = SP – TE

CM = $47 – $26.8

CM = $20.2 per unit

Mrs. Ming invested an amount of money in two accounts for one year. She invested some at 8% interest and the rest at 6% interest. Her total amount invested was $1,500. At the end of the year, she had earned $106.40 in interest. How much had Mrs. Ming invested in the account paying 6%? $117 $680 $760 $820

[ad_1]

Answer:

The correct option is B) $680.

Step-by-step explanation:

Consider the provided information.

Her total amount invested was $1,500. At the end of the year, she had earned $106.40 in interest.

Let she invested x amount with 8% interest rate.

Total amount she invested was $1,500, thus the amount she invested with 6% interest rate was 1500-x.

Total interest she earn was $106.40

Write this information into mathematical form.

xtimes frac{8}{100}+frac{6}{100}(1500-x)=106.40

xtimes 0.08+0.06(1500-x)=106.40

0.08x+90-0.06x=106.40

0.08x-0.06x=106.40-90

0.02x=16.4

x=820

Hence, she invested $820 with 8% interest rate.

The amount she invested with 6% interest rate was 1500-x.

Substitute the value of x in above.

1500-820=680

Hence, she invested $680 with 6% interest rate.

The correct option is B) $680.

4. If you have earned income, which of the following retirement devices must you contribute to, by law?

[ad_1]

Answer:

The correct option is B) $680.

Step-by-step explanation:

Consider the provided information.

Her total amount invested was $1,500. At the end of the year, she had earned $106.40 in interest.

Let she invested x amount with 8% interest rate.

Total amount she invested was $1,500, thus the amount she invested with 6% interest rate was 1500-x.

Total interest she earn was $106.40

Write this information into mathematical form.

xtimes frac{8}{100}+frac{6}{100}(1500-x)=106.40

xtimes 0.08+0.06(1500-x)=106.40

0.08x+90-0.06x=106.40

0.08x-0.06x=106.40-90

0.02x=16.4

x=820

Hence, she invested $820 with 8% interest rate.

The amount she invested with 6% interest rate was 1500-x.

Substitute the value of x in above.

1500-820=680

Hence, she invested $680 with 6% interest rate.

The correct option is B) $680.

To answer this problem, we will use the formula of
hypotenuse:

c^2 = a^2 + b^2

Where,

c = total distance traveled / displacement = 119 miles

a = distance traveled north = 5 hours * x mph =  5 x

b = distance traveled west = 4 hours * (x + 5) mph = 4 (x
+ 5)

Substituting to the equation:

119^2 = (5 x)^2 + [4(x + 5)]^2

14,161 = 25 x^2 + 16 (x + 5)^2

14,161 = 25 x^2 + 16 (x^2 + 10 x + 25)

14,161 = 25 x^2 + 16 x^2 + 160 x + 400

0 = 41 x^2 + 160 x – 13,761

x =[ – b ± sqrt (b^2 – 4ac)]/ 2a

x = [- 160 ± sqrt (160^2 – 4 * 41 * (– 13,761))] / 2 * 41

x = – 1.95 ± 18.42

x = -20.37 , 16.47

Since speed cannot be negative, therefore x = 16.47

Therefore the speed of the ship travelling west is:

x +

1. We are asked to simplify the expression :  frac{ x^{2} +x-12}{ x^{2} -x-20}/  frac{ 3x^{2} -24x+45}{ 12x^{2} -48x-60}

2. First thing we can do is to flip the second expression, so make the division a multiplication, and also factorize 3 in the numerator and 12 in the denominator of the second expression as follows:

frac{ x^{2} +x-12}{ x^{2} -x-20}* frac{12( x^{2} -4x-5)}{3(x^{2} -8x+15)}

3. Now factorize each of the quadratric expressions using the following rule:

when we want to factorize  x^{2} +ax+b, we look for 2 numbers m and n, whose sum is a, and product is b:
for example: in x^{2} -x-20, the 2 numbers we are looking for are clearly -5 and 4, because (-5)+4=-1, (-5)*4=-20, so we write the factorized form (x-5)(x+4) 

Now apply the rule to the whole expression:

frac{(x-3)(x+4)}{(x-5)(x+4)}* frac{4(x-5)(x+1)}{(x-5)(x-3)}

4. Simplify equal terms in the numerator and denominator:

we get:  frac{4(x+1)}{(x-5)}

Answer:  frac{4(x+1)}{(x-5)}

How much interest is earned in 2 years on an investment of $2000? The interest rate is 3%

[ad_1]

Answer:

The correct answer is option B : Change the interest to 5.5%

Step-by-step explanation:

Giselle wants to buy a condo that has a purchase price of $163,000.

She earns $2,986 a month and wants to spend no more than 25% of her income on her mortgage payment.

Means the maximum she will spend is 0.25times2986=746.50 dollars.

She has saved up $33,000 for a down payment.

So, loan amount or principle will be = 163000-33000=130000 dollars

Giselle is considering the following loan option: 20% down, 30 year at a fixed rate of 6.25%.

Lets check the monthly payment for this option:

The EMI formula is:

frac{p*r*(1+r)^{n} }{(1+r)^{n}-1}

p = 130000

n = 30*12=360

r = 6.25/12/100=0.0052083

Putting the values in formula we get:

frac{130000*0.0052083*(1+0.0052083)^{360} }{(1+0.0052083)^{360}-1}

= $800.43

This option is not viable.

So, lets check other options.

1. Change to a 15 year fixed loan means n will be 15*12=180 and rest values will be same.

Putting the values in formula we get,

frac{130000*0.0052083*(1+0.0052083)^{180} }{(1+0.0052083)^{180}-1}

= $1114.66

This is not viable.

b.  Change the interest to 5.5%  

Now r = 5.5/12/100=0.004583

Rest will remain the same and n = 360

Putting the values in formula we get,

frac{130000*0.004583*(1+0.004583)^{360} }{(1+0.004583)^{360}-1}

= $738.095

This is a viable option as EMI is less than $746.50.

C. Change the down payment to 18% down

0.18times163000=29340

So, p = 163000-29340=133660

n = 30*12=360

r = 6.25/12/100=0.0052083

Putting the values in formula we get:

frac{133660*0.0052083*(1+0.0052083)^{360} }{(1+0.0052083)^{360}-1}

= $822.97

This is also not viable.

Therefore, the correct answer is option B : Change the interest to 5.5%

Zinnia and Ruby earn $58 per week for delivering pizzas. Zinnia worked for x weeks and earned an additional total bonus of $13. Ruby worked for y weeks. Which expression shows the total money, in dollars, that Zinnia and Ruby earned for delivering pizzas? (5 points) 71x + 58y 58x − 13 + 58y 58x + 71y 58x + 13 + 58y

[ad_1]

Answer:

Total money Zinnia and Ruby earned for delivering pizzas is 58x + 13 + 58y .    

Step-by-step explanation:

As given

Zinnia and Ruby earn $58 per week for delivering pizzas.

Zinnia worked for x weeks and earned an additional total bonus of $13.

Ruby worked for y weeks.

Thus

Money Zinnia earns = Money earns per week × Number of weeks + Additional total bonus .

Put all the values in the above

Money Zinnia earns = 58 × x + 13

Money Zinnia earns = 58x + 13

Thus

Money  Ruby earns = Money earns per week × Number of weeks

Put all the values in the above

Money  Ruby earns = 58 × y

Money Ruby earns = = 58y

Thus

Total Zinnia and Ruby earned for delivering pizzas = Money Zinnia earns  + Money Ruby earns

Total Zinnia and Ruby earned for delivering pizzas = 58x + 13  + 58y

Therefore the total money Zinnia and Ruby earned for delivering pizzas is 58x + 13 + 58y .
