The Hendersons have just bought a home that requires some monthly yard maintenance. They are trying to decide if they should hire a professional lawn care service to maintain the property or do it themselves. Below are the costs associated with both options:Professional Service Option Do-It-Yourself Option
$75 for the first month $250 lawnmower
$45 per month after initial visit $135 edger
Includes mowing and edging the $69 hedge trimmer
lawn, trimming the bushes, and $25 rake
raking the leaves.

How long would it take before the Hendersons would recover their costs if they chose to do it themselves over the professional service?
a.
5 months
b.
9 months
c.
10 months
d.
6 months

Answers

First, add together the costs for buying their own stuff. 250+135+69+25=479.

Then figure for the professional costs. Put it in perspective of a year. 45*11+75=570.

Then subtract. Professional- DIY. 570-479=91.

$91 is about 2 months worth of work. So a year has 12 months.

12-2=10

Answer:10 months

Professional Service Option Do-It-Yourself Option:

First month lawnmower = $250

Initial visit = $135

Price for mowing and edging = $69

Price for lawn and bushes trimming = $ 25

Hence, total cost becomes = 250+135+69+25 = $479

Professional service cost for 1 month lawnmower = $75

Professional cost for visit for 11 months (1st visit costs $135) = $45

Total cost for 11 months = 45*11 = $495

Total professional cost = 495+75 = $570

Now, subtracting the professional cost and do it yourself cost we get;

$570-$479=$91.

This $91 is for 2 months worth of work. Hence, months needed to recover costs = 12-2 = 10 months

Hence, the answer is 10 months.

From where Kiana is standing she must look up at a 50° angle to see the top of a building she backs up 50 feet she will need to look up a 40° angle to see the top of the same building approximately how tall is the building

Answers

For this case, what we must do is solve the following system of equations: tan (50) = h / x tan (40) = h / (x + 50)

Solving the system we have: (x + 50) * tan (40) = h (x) * tan (50) = h

Matching: (x + 50) * tan (40) = (x) * tan (50)

Rewriting: x (tan (50) - tan (40)) = 50 * tan (40) x = 50 * tan (40) / (tan (50) - tan (40)) x = 118.9692621

Substituting: h = (x) * tan (50) h = (118.9692621) * tan (50) h = 141.7820455

It takes 6 hours to travel 372 miles how many hors will it take to travel 279

Answers

Answer:

It takes 4.5 hours to travel 279 miles or it takes 4 hours 30 minutes to travel 279 miles

Step-by-step explanation:

Consider the provided information.

It takes 6 hours to travel 372 miles

It can be written as:

6 hours = 372 miles

6 hours ÷ 372 = 1 miles

$1\ miles = (6\ hours)/(372)$

Now we need to calculate how many hours will it take to travel 279.

Multiply both the sides by 279.

$1\ miles * 279= (6\ hours)/(372)* 279$

$279\ miles = 0.01613\ hours * 279$

$279\ miles = 4.5\ hours$

We can convert 4.5 hours into minutes:

Here 0.5 represents the half of 60 minutes i.e 30 minutes.

Thus it take 4 hours 30 minutes to travel 279 miles.

Hence, it takes 4.5 hours to travel 279 miles or it takes 4 hours 30 minutes to travel 279 miles

372/6=62 meaning they are traveling 62 mph 279/62=4.5 so it will take them 4.5 hours to travel 279 miles

Which scenario best matches the linear relationship expressed in the equation y = 32x + 80?Joseph has $80 in his bank account and spends $32 each day.
Joseph has $80 in his bank account and earns $32 each day.
Joseph had $32 in his bank account and deposited another $80.
Joseph has $32 in his bank account and earns $80 each day.

Answers

Answer:

Option (2) best matches the given the linear relationship y = 32x + 80

Step-by-step explanation:

Given linear relationship as y = 32x + 80

We have to find the best match from the given options to the given the linear relationship.

1) Joseph has $80 in his bank account and spends $32 each day.

Let the money Joseph spend each day be $x

Since, the amount one spend gets deducted from the money one have.

So, given statement is represented as y = 80 - 32x .

2) Joseph has $80 in his bank account and earns $32 each day.

Let the money Joseph earns each day be $x

Since, the amount one earns gets added to the money one have.

So, given statement is represented as y = 80 + 32x .

3) Joseph had $32 in his bank account and deposited another $80.

Since, he is depositing money in account so it gets add up

So, given statement is represented as y = 32 + 80 = 112

4) Joseph has $32 in his bank account and earns $80 each day.

Let the money Joseph earns each day be $x

Since, the amount one earns gets added to the money one have.

So, given statement is represented as y = 32 + 80x .

Out of all four option, option (2) best matches the given the linear relationship y = 32x + 80

he has 80 in the bank account and earns 32 each day....where x represents the number of days and y represents the total in the account

moving company a charges 45$ on arrival and $25 an hour. The final bill was $470. How many hours did the movers work?

Answers

17 hours because if it's $25 an hour then you multiply 17 times 25 and you get 425 then you add the arrival money which is $45 then you get $470 :)

Log x + log 8 = 2 ???

Answers

To start we will use the sum to product rule of logs to make logx + log 8 = 2 -> log8x = 2. now assuming that this is log base 10 we will get rid of the log by raising both sides to the power of ten.

8x = 10^2
8x = 100
x = 100/8

The solution to the equation $log(x) + log(8) = 2$ is $x = 12.5$ .
