Answer:
2 dollars
Step-by-step explanation:
The drama club is having a car wash as a fundraiser. They wash x cars at $5 each
and y trucks at $8 each. They will wash at least 26 cars and 15 trucks. They need to
make at least $250. Which system describes this situation?
Answer:
x + y ≥ 26 + 15
5x + 8y ≥ 250 (see below)
Step-by-step explanation:
First, write an equation to represent the total cost to wash cars:
$5x = cost for cars
Then, write another for trucks:
$8y = cost for trucks
If the question is saying that they will wash at least 26 cars and 15 trucks, that means they could wash more. This means that we'll need an inequality:
This inequality represents that the total number of cars and trucks they wash will be at least—which means that it is equal to or greater than—than the amount given:
x + y ≥ 26 + 15
Any equation or inequality with two unknowns is not solvable, meaning we need a system of equations:
If they make at least $250, that means that we need to combine the costs of the cars and trucks to make an inequality:
5x + 8y ≥ 250
Now you have your system of equations:
x + y ≥ 26 + 15
5x + 8y ≥ 250
In one ancient civilization, hunters shared fresh meat with other individuals in a group without an explicit timeframe or agreement about who would do what in return. However, the favor would surely be returned by those in the tribe who could cook, take care of children, and provide shelter. What type of economy does this MOST closely describe? A. socialist economy B. gift economy C. market economy D. planned economy
Answer:
It is a gift economy
Step-by-step explanation:
This is correct on playto, but let me give you an explanation. A gift economy is a explicit agreement between two parties that if a favor is given, it'd be returned at a later time. If a hunter shared meat with others, the hunter expects to get something later in returned. By defintion, this is the role of a gift economy.

What is a trapezoid?It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a trapezoid, one pair of opposite sides are parallel.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
In the isosceles trapezoid, the sum of the opposite angle is 180 degrees. Then the equation is given as,
∠NMQ + ∠NPQ = 180°
∠NPQ + 32° + 30° = 180°
∠NPQ = 118°
The measure of the angle ∠NPQ will be 118°. Then the correct option is C.

A retailer sold an article to a customer at a loss of 10%. The customer purchased
it for Rs 25,425 including 13% VAT. Calculate the cost price of the article to the
retailer.
those who do this question i will mark us as a brilliant
Answer:
loss=10%
sp with vat=rs25425
sp=sp with vat-vat%of sp=rs25425-13/100×sp
sp+13/100×sp=rs25425
(100sp+13sp)/100=rs25425
113sp=rs2542500
sp=rs2542500/113=22500
cp=sp+loss %of cp
cp-10/100×cp=22500
(10cp-cp)/100=22500
9cp=2250000
cp=2250000/9=250000
A percentage is a way to describe a part of a whole. The cost price of the article is Rs. 25,000.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Let the selling price of the article be represented by x. Since the customet paid 13% vat , therefore,
x + 13% of x = Rs. 25,425
x + 0.13x = 25,425
1.13x = 25,425
x = 22,500
Thus, the selling price is 22,500.
Since the retailer had a 10% loss, therefore, the selling price will be 90% of the cost price.
90% of cost price = selling price
0.90×Cost price = 22,500
Cost price = 25,000
Hence, the cost price of the article is Rs. 25,000.

A. 13 units is the right answer.Ben reads 6 pages of a book in 8 minutes, 9 pages in 12 minutes, and 30 pages in 40 minutes. If m represents the number of minutes and p represents the number of pages, which equation represents the number of pages Ben reads per minute? A m=34p B p=34m C p=m+43 D m=p+34
The required proportional relationship is given a p = 3/4 m. Optio B is correct.
Given that,
Ben reads 6 pages of a book in 8 minutes, 9 pages in 12 minutes, and 30 pages in 40 minutes. If m represents the number of minutes and p represents the number of pages.
proportionality is defined as between two or more sets of values, and how these values are related to each other in a sense are they directly proportional or inversely proportional to each other.
As here, in the question there is no mention of any kind of intercept thus the relationship explained is the proportionality relation between the number of pages P and the number of minutes m.
According to the question,
P ∝ M
P =Km - - - - - (1)
Put one ordered pair from the given,
6 = K 8
K = 3 / 4
Put K in equation 1.
P = 3 / 4 m
Thus, the required proportional relationship is given a p = 3/4 m.

Which equation represents exponential decay?
O A y = 100(31)
O B. y = 1 (3.1)
C. y = 10(0.13)
D. y = 100(1.03)
Answer:
The function y = 10(0.13)ˣ represents exponential decay.
Hence, option C is the correct function.
Step-by-step explanation:
We know that an exponential function is of the form
y = abˣ
where 0 < b < 1
Please note that an exponential function cannot have a base of 0, 1, or a negative value.
Now, if we carefully observe, the function y = 10(0.13)ˣ is the only option correct as
here 0 < b < 1 and a > 0
Therefore, the function y = 10(0.13)ˣ represents exponential decay.
Hence, option C is the correct function.

The size of angle AED is 173°
How to find the size of angle AED?In geometry, an angle is the figure formed by two rays (i.e. the sides of the angle) sharing a common endpoint (i.e. vertex).
Angles formed by two rays lie in the plane that contains the rays. Angles are also formed by the intersection of two planes.
The size of angle AED can be determined as follow:
In ΔBCE,
∠BEC + 73° + 79° = 180° (The sum of angles on a triangle is 180°)
∠BEC = 180 - 73 - 79
∠BEC = 28°
Also, in ΔCDE,
∠BEC + 37° + 96° = 180° (The sum of angles on a triangle is 180°)
∠CED = 180 - 37 - 96
∠CED = 47°
∠BED = ∠BEC + ∠CED
∠BED = 28 + 47
∠BED = 75°
∠AED + ∠BED + ∠AEB = 360° (The sum of angles at a point is 360°)
∠AED + 75° + 112° = 360°
∠AED = 360 - 75 - 112
∠AED = 173°
Therefore, the size of angle AED is 173°.

What is the y-intercept of the line that passes through the points (2,-1) and (-3,9)
Answer:
The equation of the straight line y = -2x +3
y-intercept = 3 and m =-2
Step-by-step explanation:
Step(i):-
Given that the points are ( 2,-1) and (-3,9)
The slope of the line
[tex]m = \frac{y_{2}-y_{1} }{x_{2} -x_{1} } = \frac{9-(-1)}{-3-(2)} = \frac{10}{-5} = -2[/tex]
Step(ii):-
The equation of the straight line passing through the point ( 2,-1) and slope m=-2
y-y₁ = m( x- x₁)
y -(-1) = -2 ( x-2)
y +1 = -2x +4
2x +y +1-4 =0
2x +y -3 =0
Final answer:-
The equation of the straight line y = -2x +3
