Joel used a half gallon of paint to cover 84 square feet of wall he has 932 square feet of walls of paint how many gallons of paint should you purchase
Answer:
About 6 gallons of paint
Step-by-step explanation:
[tex]\frac{0.5}{84}[/tex] = [tex]\frac{x}{932}[/tex]
84x=932(0.5)
84x=466
x = 5.55
round up to get about 6 gallons of paint
The number of the gallon of paint is need will be 5.547 gallons of paint.
What are ratio and proportion?A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.
Joel used a half gallon of paint to cover 84 square feet of wall.
Then in one gallon of paint he can cover 168 square feet.
He has 932 square feet of walls of paint.
Then the number of the gallon of paint is need will be
⇒ 932 / 168
⇒ 5.547 gallons of paint

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.
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: 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.

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
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?
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.

3.75 feet

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.

When we put toast in the toaster he didn't do anything but heat up the toast, so the property and identity of this piece of toast hasn't changed at all. When we put jam and peanut butter on it all it did was add flavor to it still didn't change the identity. But when we cut the apple in to a lot of slices the property of the apple has changed and the weight is different and the chemical property isn't the same. ( it is totally different)

Step-by-step explanation:
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
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.
