Step-by-step explanation:

Supply describes the amount of product a seller is able to make.

Demand is defined as the amount of product that the consumers or buyers is going to buy.

Supply is defined as the amount of product that the producers or sellers is going to make to sell.

Market is the place where the demand and supply meet. That is, sellers and buyers will be meeting at the market.

From the definition, it is clear that demand is related to buyers than the sellers.

So demand is the quantity that the buyers buy.

So supply is referred to as the quantity that the seller is going to make.

Hence the best description for the amount of product a seller is able to make is supply.

Answer: 34/10=3.4 The estimated quotient is 3.4

Step-by-step explanation: Basically,  you are dividing 33.7 by 9.5, but first you will need to round to the nearest whole number. A whole number does not contain a decimal. 33.7 rounded to the nearest whole number is 34. 9.5 rounded to the nearest whole number is 10. So, you are dividing 34 by 10.  34 divided by 10 is 3.4.

The quotient of 33.7/9.5, rounded to the nearest whole number is: 4.

Therefore, the quotient between 33.7 and 9.5 would be:

33.7/9.5 = 3.547 (division).

We are asked to round to the nearest whole number.

Therefore, the quotient of 33.7/9.5, rounded to the nearest whole number is: 4.

Answer:

-3/5

Step-by-step explanation:

First represent this with numbers. Less means subtraction -, times means multiplication *, is means equals =.

And let's represent "a number" with x.

63 - 15x = 72

Solve for x. First subtract 63 from both sides.

-15x = 72-63

-15x = 9

x = -9/15 = -3/5

Answer:

-3/5

Step-by-step explanation:

The equation would be represented as 63 - 15 x X = 72

To further simplify the problem : 63 - 15x = 72

Then you subtract

- 15x = 9

a) The absolute value equation is |x - 11| = 6.

b) The absolute value equation is |x - 0| = 1/2, which simplifies to |x| = 1/2.

To write the absolute value equation in the form |x - c| = d for the given solution sets, we need to find the midpoint (c) between the two values and the distance (d) from the midpoint to either of the values.

b) For the solution set x = 5, x = 17:

Midpoint (c) = (5 + 17) / 2 = 22 / 2 = 11

Distance (d) from the midpoint to either value (e.g., 5) = |5 - 11| = 6

So, the absolute value equation is |x - 11| = 6.

d) For the solution set x = -1/2, x = 1/2:

Midpoint (c) = (-1/2 + 1/2) / 2 = 0 / 2 = 0

Distance (d) from the midpoint to either value (e.g., 1/2) = |-1/2 - 0| = 1/2

So, the absolute value equation is |x - 0| = 1/2, which simplifies to |x| = 1/2.

a) x=5, x=17

b) x=-1/2, x=1/2

Answer:

19

Step-by-step explanation:

The length of line segment RT is found by adding the lengths of the segments RS and ST. Given RS=2 and ST=17, we find that RT=2+17=19.

In this problem, we are dealing with segments on a line. There is a concept in mathematics that's relevant here: the Whole is the sum of its parts. When you have a line divided into segments (parts), the length of the whole line is the sum of the lengths of these parts. Here, line segment RT is divided into two parts - RS and ST.

We know that RS = 2 (given) and ST = 17 (also given). Therefore, the length of line segment RT is the sum of RS and ST. RT = RS + ST = 2 + 17 = 19. So, the length of RT is 19 units.

Given:

Triangles FRI and DAY are similar.

To find:

Similarity ratio

Solution:

If two triangles are similar then the corresponding angles are congruent and the corresponding sides are in proportion.

Here, FR and DA are corresponding sides.

[tex]$\Rightarrow \frac{FR}{DA} =\frac{4}{6}[/tex]

Cancel the common factors of 4 and 6, we get

[tex]$\Rightarrow \frac{FR}{DA} =\frac{2}{3}[/tex]

⇒ FR : DA = 2 : 3

⇒ ΔFRI : ΔDAY = 2 : 3

Similarity ratio of the first triangle to the second triangle is 2 : 3.

The similarity ratio should be 2:3

In the case when two triangles are same so the corresponding angles are congruent and the corresponding sides should be in proportion.

So,

[tex]FR \div DA = 4\div 6[/tex]

FR:DA = 2:3

Based on the above calculations, we can say that the ratio of first triangle to the second triangle should be 2:3

Final answer:

The volume of the brick patio is 40 cubic feet, and by using the density of brick (130 pounds per cubic foot), the weight is found to be 5200 pounds.

Explanation:

To find the volume of the brick patio, we multiply its length, width, and height, keeping in mind to convert all dimensions to the same unit. The brick patio measures 10ft by 12ft by 4in. Since 1 foot is equal to 12 inches, the height in feet is 4in * (1ft / 12in) = 1/3 ft. Now, the volume can be calculated as follows:

Volume = Length × Width × Height
Volume = 10ft × 12ft × (1/3)ft
Volume = 120ft × (1/3)ft
Volume = 40 cubic feet.

To find the weight of the patio, we use the given density of brick, which is 130 pounds per cubic foot, and the volume that we have just calculated:

Weight = Density × Volume
Weight = 130 lbs/ft³ × 40 ft³
Weight = 5200 pounds.

The weight of the brick patio is therefore 5200 pounds.

Given points (4 , -4) and ( 1, 2)

First calculating slope (m)

=( y2 - y1) /( x2 -x1)

= ( 2 + 4) / (1-4)

= 6/ -3

= -2

Now

The equation in point slope form

y - y1 = m ( x - x1)

y + 4 = -2 ( x - 4)

y + 4 = -2x + 8

2x + y - 8 + 4 = 0

2x + y -4 = 0 which is the required equation

The solution of the system is x = - 1 and y = 8/3.

One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.

We have a system of equations,

2x+3y=6  {equation 1}

-4x+3y=12  {equation 2}

Subtracting equation 2 to equation 1,

2x - (-4x) = 6 - 12

6x  = - 6

x = - 1.

And y = 8/3

Therefore, the solution is x = - 1 and y = 8/3.

Answer:

21%

Step-by-step explanation:

okay so 400 is your denominator, and 84 is your numerator, so divide 400 by 4 so you get 100, because your percentage should be out of 100. because you divided 400 by 4, you also have to do that for 84, giving you 21 out of 100. converted to a decimal its .21, or 21%

Final answer:

To find the percentage of seventh grade students who made honor roll, a proportion is used, yielding a result of 21 percent.

Explanation:

To calculate the percentage of seventh grade students who made honor roll, we can set up a proportion where 84 students is to 400 students as x percent is to 100 percent. The proportion can be written as 84/400 = x/100. To find x, we cross-multiply and solve for x.

First, cross-multiply: 84 * 100 = 400x. This gives us 8400 = 400x. Next, divide both sides of the equation by 400 to solve for x: 8400 / 400 = x. This results in x being equal to 21. Therefore, 21 percent of the seventh grade students made honor roll.

D.The range is all positive multiples of 3.5 rounded to the nearest hundredth because the amounts charged are represented as dollars and cents.

Step-by-step explanation:

The domain of a function c(x) is the set of all values, x for which the function f is defined, while the range of the function is the set of all values that c takes.

If the Book Editor , Wallace uses the function c(x) = 3.5x to determine the amount he will charge, in dollars, to edit a book with x pages. The statement that best explains the range of his function is Option D.

This is as a result of the fact that, although the number of pages,x will be positive whole numbers, multiplying x by 3.5 makes the function c(x) a positive multiple of 3.5.

Since c(x) is in dollars, we round it up to the nearest cent (hundredths).
