the Strauss family is deciding between two lawn care services Green Lawn start charges a $49 startup fee plus $29 per month grass team charges a $25 startup fee plus that $37 per month and how many months will both line care services cost the same what will be the cost
Final answer:
Both lawn care services, Green Lawn and Grass Team, will cost the same after 3 months, with each service costing a total of $136 at that point.
Explanation:
The student asked at how many months will both lawn care services, Green Lawn and Grass Team, cost the same and what will be that cost. To solve this, we set up an equation with Green Lawn's cost model: $49 (startup fee) + $29 per month (monthly fee) and Grass Team's cost model: $25 (startup fee) + $37 per month (monthly fee). Let m represent the number of months.
The equation will look like this:
49 + 29m = 25 + 37m
To find the number of months where the costs are the same, we will solve for m:
Subtract 29m from both sides: 49 = 25 + 8mSubtract 25 from both sides: 24 = 8mDivide both sides by 8: m = 3Therefore, both services will cost the same after 3 months. The total cost at this point will be calculated by substituting m back into either cost model (we will use Green Lawn's model):
Total Cost = 49 (startup fee) + (29 × 3) (3 months of service)Total Cost = 49 + 87Total Cost = $136
what is .41 as a fraction
Answer: 41/100
Step-by-step explanation: First, we can change .41 to 0.41 by putting a zero in front of the decimal point.
Using the place value chart, we can see that 0.41 means 0 units, 4 tenths a 1 hundreth. Think of 4 tenths and 1 hundredth as 41/100 so we have 41/100.
Since the fraction 41/100 is in lowest terms, this is our final answer.
y = -1/4x + 2 and 2y = 1/2x - 4
how do these lines compare?
Answer:
the line 1 has negative slope of -1/4 and line 2 has positive slope of 1/4.
Step-by-step explanation:
let the line 1 be y = -1/4x + 2 and line 2 be 2y = 1/2x - 4
these lines are in the form of y = mx + c
where m is the slope of the line and c is the intercept made with y axis.
dividing the line 2 by 2 we get [tex]y = \frac{1}{4}x -2[/tex]
line 1 meets x axis when y = 0 applying y = 0 in equation 1 we get x = 8
line 2 meets x axis when y=0 applying y = 0 in equation 2 we get x = 8
line 1 meets y axis when x = 0 applying x= 0in equation 1 we get y = 2
line 2 meets y axis when x = 0 applying x= 0in equation 2 we get y = -2
therefore line 1 passes through (8,0)and (0,2) with negative slope of -1/4
and line 2 passes through (8,0) and (0,-2) with positive slope of 1/4.

A radio dealer makes a radio with the price 20% above the cost price and allows 10% discount on it. Find his gain percent
Answer:
10%
Step-by-step explanation:
Good morning,
Answer:
8%Step-by-step explanation:
Let x be the cost price and
y the final sell price
p gain percent
the gain precent p = (20/100)-(10/100)-[(20×10)/(100×100)]
= (20-10)/100 - 2/100
= 10/100 - 2/100
= 8/100
example : x=20
x(1+20/100)(1-10/100) = 20(1+20/100)(1-10/100) = 20(120/100×90/100)
= 20(10 800÷10 000)
= 21.6
20+20p% =21.6 then 20p%=1.6 then p%=1.6/20=16/200=8/100 then p=8.

Express the ratio below in its simplest form.
1/3:1/4
how do you sinplify fractions in ratios
Answer:
4/3
Step-by-step explanation:
(1/3)/(1/4)
(1/3)(4/1)
4/3
The ratio 1/3:1/4 is simplified to 4:3 by finding a common denominator. In the given proportion with a scale factor, cross-multiplication is used to find the actual dimension which results in x=8 when the scale dimension is 4.
To express the ratio 1/3:1/4 in its simplest form, find a common denominator for the two fractions, which in this case is 12. The fraction 1/3 is equivalent to 4/12, and 1/4 is equivalent to 3/12. Therefore, the ratio 1/3:1/4 becomes 4/12:3/12. Since both denominators are the same, they can be canceled out, leaving us with the simplified ratio 4:3.
Now, let's apply this to a problem with a scale factor. For the proportion 1:2=4:x, to find the value of x, you can cross-multiply. This gives us 1*x = 2*4 which simplifies to x=8. Therefore, if the scale dimension is 4, the actual dimension is 8.

A researcher conducted a study investigating the effect of computer screen time on a person’s amount of REM sleep. The researcher randomly assigned 100 people into four groups. The first group was given 2 hours of computer screen time each day, the second group was given 4 hours each day, the third group was given 6 hours each day, and the fourth group was given 8 hours each day. The study was conducted for one week, and the amount of REM sleep for each person was measured. What is the explanatory variable in the study?
Answer:
Amount of screen time
Step-by-step explanation:
Explanatory variables are those variables that are not totally independent and are used to predict or explain differences in the response variable.
Having pointed what an explanatory variable is, we'll list the explanatory variable(s) in the question, using the definition above.
The Variable used to predict results here is the amount of screen time.
In that case, it is the explanatory variable.
And it's of numerical type.
In the described study, the explanatory or independent variable is the amount of computer screen time each day, as it is the variable that is being manipulated by the researcher in order to examine its effect on REM sleep.
Explanation:In this particular research study, the explanatory variable, or the independent variable, is the amount of computer screen time each day. This is because the explanatory variable is the factor manipulated by the researcher to observe any potential effects on the outcome variable, which in this case, is the amount of REM sleep.
The participants were divided into four different groups, each exposed to a different amount of screen time: 2 hours, 4 hours, 6 hours, and 8 hours. These varying hours of exposure were purposely manipulated by the researcher to observe and measure any differences in the REM sleep duration. Therefore, the computer screen time is the explanatory variable or cause, and the observed alterations to the REM sleep will be the response, or the dependent variable.

A history Club sold rolls of wrapping paper as a fundraiser. The wrapping paper was sold in small rolls and large rolls. The club earned $3 for every small roll sold. The club earned $4.50 for every large roll sold. The club sold 10 more large rolls than small rolls. The club collected $135 more from sales of large rolls than from sales of small rolls. The equation 3 S + 135 = 4.5( s + 10) can be used to represent this situation, where s represents the number of small rose the club sold. How many small roles did the history Club sell? Of wrapping paper as a fundraiser. The wrapping paper was sold and small rose and large Rose. The club earn $3 for every small role sold. The club sold 10 more large rolls than small rolls. The club collected $135 a more from sales of large rolls than from sales of small rolls. The equation 3x + 135 = 4.5(s + 10) can be used to represent this situation, where s represents the number of small rolls the club sold. How many small rolls did the history Club sell?
Answer:
hence small rolls 60 and large rolls 70
Step-by-step explanation:
let club sold s small rolls
hence club sold s+10 large rolls
earning from small roll 3s
earning from large rolls 4.5(s+10)
hence
4.5(s+10) - 3s = 135
or 4.5(s+10) = 3s +135
3s +135 = 4.5(s+10)
3s +135 = 4.5s +45
4.5s +45 = 3s +135
4.5s -3s = 135-45
1.5s = 90
s = 90/1.5
s= 60
s+10 = 70
hence small rolls 60 and large rolls 70
The history club sold 60 small rolls of wrapping paper according to the given equation.
Explanation:The subject here is Mathematics, specifically algebra. The equation given by the problem, 3S + 135 = 4.5(S + 10), can be solved to find 'S', which represents the number of small rolls sold by the history club. Start by distributing the 4.5 across the (S + 10) on the right side of the equation. This gives 3S + 135 = 4.5S + 45. Subtract 3S from both sides of the equation to get 135 = 1.5S + 45. Subtracting 45 from both sides then gives 90 = 1.5S. Finally, divide each side of the equation by 1.5 to get S = 60. So, the history club sold 60 small rolls.

Selena is standing on a rock cliff that is 52 feet high. She tosses a pebble upward over the edge, where it hits the top of a 12 foot high boulder. The quadratic equation that models the path of the pebble is given below. How long did it take for the pebble to hit the top of the boulder? p(t)=-16t^2+12t+52
Answer: At [tex]t=\dfrac{3}{8}[/tex], the pebble hit the top of the boulder.
Step-by-step explanation:
Since we have given that
Distance at which Selena is standing on a rock cliff = 52 feet
Height of boulder above a rock cliff = 12 foot

If 3(d+1)=4(d–2), then what is the value of 5(d–2)?
Answer:
Ans => 45
Step-by-step explanation:
3(d+1) = 4(d-2)
Expanding the brackets we have:
3d + 3 = 4d - 8
our aim now is to solve for d
3d - 4d = -8 - 3
-d = -11
=> d = 11
we can now get 5(d-2)
substituting d = 11
5(11-2)
5(9)
= 45
The value of 5(d-2) is 45.
3(d+1)=4(d–2)
3d + 3 = 4d - 8.
3d - 4d = -8 - 3.
-d = -11
d = 11
Substitute d = 11 into 5(d–2):
5(d-2)=5(11-2)
= 5(9)
= 45.

1 What is the length of carpet for carpeting the
floor of 45 m long square room with 9 m width carpet?if
cost of the carpet per meter is Rs. 225, find the total cost
of carpeting the room
Answer:
The length of the carpet = l = 5 meter
The cost of carpeting the room is Rs 6300 .
Step-by-step explanation:
Given as :
The area of the room = 45 m²
The width of the carpet = w = 9 m
Let The length of the carpet = l meter
The cost of the carpet per meter = Rs 225
Let The cost of carpeting the room = Rs x
Now, According to question
The Area of room = length × breadth
Or, 45 m² = l m × b m
Or, 45 m² = l m × 9 m
∴ l = [tex]\dfrac{45}{9}[/tex]
i.e l = 5 m
So, The length of the carpet = l = 5 meter
Again
Perimeter of carpet = 2 × length + 2 × width
Or, Perimeter of carpet = 2 × 5 m + 2 × 9 m
Or, Perimeter of carpet = 28 meters
∵ The cost of carpet per meter = Rs 225
∴ The cost of carpeting the room = Rs 225 × 28
i.e The cost of carpeting the room = Rs 6300
Hence, The length of the carpet = l = 5 meter and The cost of carpeting the room is Rs 6300 . Answer
