It normally takes Julius 2 hours to mow the yard, but because he is in a hurry he asks his son, Marcos, to help him. If just his son was doing the yard work it would take him 3 hours. How long will it take if both are working together? Use the formula 1/T_1 +1/T_2 =1/T_both where T_1 is the time required for Julius to complete the job alone, T_2 is the time required for Marcos to complete the job alone, and T_both is the time required to complete the job when they both work together. Answer as a decimal, rounded to one decimal place.
Answers
Answer: 1.2 hours
Step-by-step explanation:
Given: : Time taken by Julius to complete the job alone: [tex]T_1=2\text{ hours}[/tex]
Time taken by Marcos to complete the job alone : [tex]T_2=3\text{ hours}[/tex]
Let the time taken by both to complete the job together = T
[tex]\dfrac{1}{T}=\dfrac{1}{T_1}+\dfrac{1}{T_2}[/tex]
[tex]\Rightarrow\ \dfrac{1}{T}=\dfrac{1}{2}+\dfrac13\\\\\Rightarrow\ \dfrac{1}{T}=\dfrac{3+2}{2\times3}\\\\\Rightarrow\ \dfrac{1}{T}=\dfrac{5}{6}\\\\\Rightarrow\ T=\dfrac{6}{5}=1.2[/tex]
Hence, it will take 1.2 hours to complete the job by working together.

Answer:
Possible rational roots: ±1,±5.
Actual rational roots: −1,5.
Step-by-step explanation:
The trailing coefficient (coefficient of the constant term) is −5.
Find its factors (with plus and minus): ±1,±5. These are the possible values for p.
The leading coefficient (coefficient of the term with the highest degree) is 1.
Find its factors (with plus and minus): ±1. These are the possible values for q.
Find all possible values of pq: ±11,±51.
Simplify and remove duplicates (if any), these are possible rational roots: ±1,±5.
Next, check the possible roots: if a is a root of the polynomial P(x), the remainder from the division of P(x) by x−a should equal 0.
Check 1: divide x3−3x2−9x−5 by x−1.The quotient is x2−2x−11 and the remainder is −16
Check −1: divide x3−3x2−9x−5 by x+1.The quotient is x2−4x−5 and the remainder is 0
So, −1 is a root.
Check 5: divide x3−3x2−9x−5 by x−5.The quotient is x2+2x+1 and the remainder is 0
So, 5 is a root.
Check −5: divide x3−3x2−9x−5 by x+5.The quotient is x2−8x+31 and the remainder is −160
q= lead coefficient of highest term which is x^3 which has a leading coefficient of 1.
2. P=±1,±5, Q=±1. You would divide the factors of the constant by the factors of the leading coefficient.
3. Possible roots for this equation. ±1,±5.
4. Factor the equation.
x³-3x²−9x−5
x³+x²−4x²−4x-5x-5
x²(x+1)-4x(x+1)-5(x+1)
(x+1)(x²-4x-5)
(x+1)(x-5)(x+1)
5. Set all of the factors to zero and solve for x to get your rational roots to the equation.
x+1-1=0-1
x=-1
x+1-1=0-1
x=-1
x-5+5=0+5
x=5
6. Final Solution:
Possible Rational Roots: ±1, ±5

Andy works at a grocery store. The manager of the store would like Andy to set up a display of apples. Part of the display will include bags of apples. If there are 39 pounds of apples in the back of the store, how many bags of apples can Andy make for the display? each bag has 1 1/2 pound
Answers
Answer:
Andy can make 26 bags for the display.
Step-by-step explanation:
Quantity of apples in the back of the store = 39 pounds
Quantity of apples in one bag = [tex]1\frac{1}{2}[/tex] pounds
Here,
[tex]1\frac{1}{2}=\frac{2(1)+1}{2}=\frac{3}{2}[/tex]
Number of bags = Quantity of apples in the back of the store / Quantity of apples in one bag
[tex]=\frac{39}{1\frac{1}{2} }=\frac{39}{\frac{3}{2} }=39(\frac{2}{3})=26[/tex]
So, Andy can make 26 bags for the display of apples.

Answer:
The pool is 400 square meters
Step-by-step explanation:
To figure out the are of a slanted shape such as this, we must turn it into a shape that is non-slanted, like a rectangle or square (which is a type of rectangle). For this parallelogram, we can separate the shape into three parts: the two slanted bits on the outside, and a rectangle (7*2) in the middle (or on the inside).
We can see that each slanted part can take up half of two squares, and therefore one square. From here on out, we can do this one of two ways:
1. Figure out the area of the inside rectangle, then add the two slanted parts/two squares separately
OR
2. Since each slanted area equals one square, or since each is half of two square, we can add both sides together (for 1/2 + 1/2 = 1, or in this case, 1 +1 = 2), to make a full or complete rectangle, before figuring out the area of the shape as a whole (8*2).
8*2 = 16
Each square is 1 cm squared, which is in proportion to 25 meters squared (each cm is 5 meters (1:5), so the square, which is 1 cm by 1 cm, is proportionate to 5 meters by 5 meters).
16*25 = 400
The pool is therefore 400 square meters.

A new underground rollercoaster is being installed. The height of the rollercoaster in feet throughout the underground section is modeled by the equation h(d) = 0.15d2 – 1.5d, where d represents horizontal distance in feet. What's the height of the rollercoaster 6 feet horizontally through the underground section?
Answers
Answer:
3.6 feet
Step-by-step explanation:
The height of the rollercoaster in feet throughout the underground section is modeled by the equation :
[tex]h(d) = 0.15d^2 - 1.5d[/tex] ....(1)
We need to find the height of the rollercoaster 6 feet horizontally through the underground section.
Put d = 6 feet in equation (1) as follows :
[tex]h(6) = 0.15(6)^2 - 1.5(6)\\\\h=-3.6\ \text{feet}[/tex]
or
h = 3.6 feet
So, the height of the rollercoaster 6 feet horizontal through the underground section is 3.6 feet.

Answer: I recommend starting treatment immediately. If you take more than 8 days to make a decision, the disease can no longer be cured because it will affect more than 50% of the body.
Step-by-step explanation:
The percentage of the body affected by the disease is a function of the number of days:
P(d) = 6d + 5This percentage is a dependent variable and the number of days is the independent variable.
If we give values to d, we can calculate the percentage of the body affected by the disease.
P(1)= 6·1 + 5 = 11%
P(2)= 6·2 + 5 = 17%
P(3)= 6·3 + 5 = 23%
P(4)= 6·4 + 5 = 29%
P(5)= 6·5 + 5 = 35%
P(6)= 6·6 + 5 = 41%
P(7)= 6·7 + 5 = 47%
P(8)= 6·8 + 5 = 53%
Depending on the days since the beginning of the disease, the doctors have a treatment for a different stage.
Starting immediately, the treatment will be stage 1: less than 15%
Starting on day 2 or 3, the treatment will be stage 2: 15-25%
After day 3, the treatment will be stage 3: 25-50%
After day 8, there is no cure: more than 50% of the body is affected by the disease.
I recommend starting treatment immediately. If you take more than 8 days to make a decision, the disease can no longer be cured because it will affect more than 50% of the body.
