Given the equation:
y = 828000 - 2700x
Where y is the value of the building and x is the number of months of use.
Let's find when the value of the building will be $666,000.
To find when the value will be $666,000, substitute 666000 for y in the equation and solve for x.
y = 828000 - 2700x
666000 = 828000 - 2700x
Subtract 828000 from both sides:
666000 - 828000 = 828000 - 828000 - 2700x
-162000 = -2700x
Divide both sided by -2700:
[tex]\begin{gathered} \frac{-162000}{-2700}=\frac{-2700x}{-2700} \\ \\ 60=x \\ \\ x=60 \end{gathered}[/tex]The value of the building will be $666,000 after 60 months.
Now, let's convert from months to years.
Where:
12 months = 1 year
[tex]60\text{ months = }\frac{60}{12}=5\text{ years}[/tex]Therefore, the value of the building will be $666,000 after 5 years.
ANSWER:
5 years.

By using products and percentages, the grandson had the amount of $ 225 before to buy foods and beverages.
How much money did the grandson have at first?In accordance with the statement, the grandson spent 80 % of all his amount to buy some food, later 40 % of the remaining money to buy some beverages and there was $ 27 remaining. We need to determine the amount that the grandson had initially. Then, the situation can be described by the following mathematical expression:
(1 - 80 / 100) · (1 - 40 / 100) · x = 27
(20 / 100) · (60 / 100) · x = 27
(1200 / 10000) · x = 27
(12 / 100) · x = 27
12 · x = 2700
x = 2700 / 12
x = 225

A new cream was developed to reduce the irritation caused by poison ivy. To test the effectiveness, researchers placed an ad online asking for volunteers to participate in the study, and 100 subjects replied. They are informed that one group of 50 will receive a new cream and the remaining group of 50 will receive a cream with no active ingredient. The subjects are numbered 1–100 and these numbers are put into a random number generator. The first 50 unique numbers will represent the subjects that will receive the new cream and the remaining 50 subjects will receive the inactive cream. All subjects are exposed to poison ivy and given their cream. They are asked to return in three days and report their level of irritation. The average scores for each cream are compared.
Does this procedure describe a completely randomized design for this experiment?
Yes, the subjects will be exposed to the poison ivy.
Yes, the subjects are randomly assigned to each treatment.
No, the subjects are asked to return in three days. It is possible that some of them may not return, which will introduce bias into the results.

Let's see how two points on the left are mapped to their corresponding points on the right:
Point A has a corresponding point at A'. We have:
f(A) = A'
f(-6, -3) = (2, 4)
Point B has a corresponding point at B'. We have:
f(B) = B'
f(-4, -1) = (4, 6)
Now, notice that:
2 = -6 + 8
4 = -3 + 7
So, for (x, y) = (-6, -3), we have:
f(x, y) = (2, 4) = (x + 8, y + 7)
Notice that the same happens to the mapping of the other point:
4 = -4 + 8
6 = -1 + 7
So, for (x, y) = (-4, -1), we have:
f(x, y) = (4, 6) = (x + 8, y + 7)
Therefore, the rule for the transformation is

We know that the ratio of pink markers to total markers is 1:3.
This means that for every 3 markers, one of them is pink. The other 2 will be yellow markers.
We can write that the ratio of pink markers to yellow markers is 1:2, based on the last sentence. This means that if we have N yellow markers, we will have N/2 pink markers.

A change in temperature of 6°C is equivalent to a
change in temperature of 10.8°F
Explanations:From the table drawn:
A change in temperature of 1°C is equivalent to 1.8°F
A change in temperature of 2°C is equivalent to 3.6°F
Following the relationships above, we can conclude that the relationship between °C and °F is:

°F = 1.8 °C
°F = 1.8 x 6

Peter's farm has 160 meters of fencing, and he wants to fence a rectangular field thatborders a straight river. He needs no fence along the river side. Find the largest areaof Peter's farm that can be fenced.
Answers
ANSWER
3200 m²
EXPLANATION
Peter wants to build a fence around a rectangular field, except for one side because the river is there,
So, the total perimeter of the fence is,
[tex]P=W+W+L=2W+L[/tex]And this is equal to 160 m. Solving for L,
[tex]160=2W+L\text{ }\Rightarrow\text{ }L=160-2W[/tex]The area of this field is,
[tex]A=WL[/tex]Replace L with the expression we found from the perimeter,
[tex]A=W(160-2W)=160W-2W^2[/tex]The area is given by a quadratic function whose leading coefficient is negative, which means that the graph is a downward parabola and, therefore, the vertex is the maximum value of the area.
The x-coordinate of the vertex is given by,
[tex]f(x)=ax^2+bx+c\text{ }\Rightarrow\text{ }x_{vertex}=\frac{-b}{2a}[/tex]In this case, x is W, a = -2, and b = 160, so the width of the field for the maximum area is,
[tex]W_{vertex}=\frac{-160}{2(-2)}=\frac{160}{4}=40m[/tex]And the length when W = 40 is,
[tex]L=160-2W=160-2\cdot40=160-80=80m[/tex]And the area is,
[tex]A=WL=40m\cdot80m=3200m^2[/tex]Hence, the largest area of Peter's farm that can be fenced is 3200 square meters.

Karma will make $99.78 if she sells 110 pounds of rice to the vendor
Quantity of rice available with Karma = 110 pounds
A pound is a unit of weight that is mostly used in the United States, Great Britain, and other English-speaking nations. A pound is approximately 0.454 kilos. A quantity of something is said to weigh one pound if it weighs that much.
The conversion rate of pounds to grams:
1 pound = 453.59 grams
So, 110 pounds will be equal to:
110*453.59

Selling price for 5 grams = $0.01
Selling price for 1 gram:
The selling price of 5 grams/ Price for 5 grams

Selling price for 49894.9 grams = 49894.9*0.002

If Greg has 1 1/2 servings of cereal for breakfast each day, he can consume 8 breakfasts from a box of cereal.
The price of one breakfast from a regular-sized box of cereal is $0.54 if the box costs $4.29.
Greg could consume 4 additional breakfast portions from a single family-sized box.
How to find unit rate of Greg's breakfast?A regular-sized box of cereal = 12 servings
If Greg eats 1 1/2 servings for breakfast every day
Number of breakfast Greg can eat in a regular-sized box = A regular-sized box of cereal / servings of breakfast eaten everyday
= [tex]\frac{12}{\frac{11}{2} }[/tex]
=[tex]\frac{12}{\frac{3}{2} }[/tex]
multiply by the reciprocal of [tex]\frac{3}{2}[/tex]
= 12 × [tex]\frac{2}{3}[/tex]
= [tex]\frac{24}{3}[/tex]
= 8 breakfast
Cost of regular-sized box of cereal = $4.29.
Cost of one breakfast from a regular-sized box of cereal = Cost of regular-sized box of cereal ÷ Number of breakfast Greg can eat in a box
= [tex]\frac{4.29}{8}[/tex]
= 0.53625
Approximately,
$0.54 per breakfast
If Greg purchased the family-sized box of cereal that contains 18 servings
Family-sized box of cereal divided by the daily serves of breakfast is the number of breakfasts Greg can consume.
= 18 servings / [tex]\frac{11}{2}[/tex]
= 18 ÷[tex]\frac{3}{2}[/tex]
= 18 × [tex]\frac{2}{3}[/tex]
= [tex]\frac{36}{3}[/tex]
= 12 servings
Consequently, the number of additional breakfasts Greg may consume from a single family-sized package
= Number of breakfast Greg can eat in a family-sized box - Number of breakfast Greg can eat in a regular-sized box
= 12 servings - 8 servings
= 4 servings

For the inequality, we have to apply the arithmetic operation in which we do the multiplication of x and apply the inequality for the given data.
To ascertain the maximum or lowest values of a scenario with many restrictions, a system of linear inequalities is frequently utilized. Inequalities reflect a limit of what is permitted or achievable rather than a precise quantity.

step 2
Hypotenuse is AB

Adjacent side is AC
because, the opposite side is the side opposite to the given angle (35 degrees)
adjacent side is the side adjacent to the given angle (35 degrees) and the hypotenuse is the greater side of a right triangle (is the opposite side to the angle of 90 degrees)
