The equation for the statement is  ( x + 9 ) × 3 = 12 , and the value of         x is - 5   .

Step-by-step explanation:

Given as :

Let The number picked by Amy = x

Amy told to Stephanie

she add 9  to the number and multiply the sum by 3 it would be 12

So, According to statement

( x + 9 ) × 3 = 12

Or, 3 x + ( 9×3 ) = 12

Or, 3 x + 27 = 12

or, 3 x = 12 - 27

or, 3 x = - 15

∴  x = - [tex]\frac{15}{3}[/tex]

I.e x = - 5

Hence The equation for the statement is  ( x + 9 ) × 3 = 12 , and the value of x is - 5   .  Answer

Final answer:

Using a system of linear equations, we determine that the cost to rent each chair is $3 and the cost to rent each table is $6 from the party rental company.

Explanation:

To determine the cost to rent each chair and each table from the party rental company, we need to solve a system of linear equations based on the information provided:

The total cost to rent 2 chairs and 12 tables is $105.

The total cost to rent 5 chairs and 3 tables is $33.

Let's let c represent the cost of renting one chair and t represent the cost of renting one table. We can write the following system of equations:

2c + 12t = $105

5c + 3t = $33

By solving this system, we find that the cost to rent each chair (c) is $3 and the cost to rent each table (t) is $6.

Answer: The first one

Answer:

(0,5) and (10,0)

Step-by-step explanation:

The equation of the straight line is given by 2x + 4y = 20 .......... (1)

Now, point (0,5) satisfies the equation (1) as putting x = 0, we will get y = 5.

Now, point (0,10) does not satisfy the equation (1) as putiing x = 0, we get y = 5 ≠ 10

Again, point (1,2) does not satisfy the equation (1) as putiing x = 1, we get y = 4.5 ≠ 2

Now, point (1,4) does not satisfy the equation (1) as putiing x = 1, we get y = 4.5 ≠ 4

Again, point (5,0) does not satisfy the equation (1) as putiing y = 0, we get x = 10 ≠ 5

Finally, point (10,0) satisfies the equation (1) as putiing y = 0, we get x = 10 .

Therefore, only points (0,5) and (10,0) are on the graph of the line 2x + 4y = 20 (Answer)

Answer:

The points a. (0,5) and f. (10,0) will lie on the given line.

Step-by-step explanation:

The given equation of line is [tex]2x + 4y=20[/tex].

Now, it is required to check whether the given point lie on the line or not. To check it, put the points in the equation of line and if they satisfies, then the point will be on the line else not.

(a) The first point is (0,5). Put this point in the equation as,

[tex]2x + 4y=20\\2\times0+4\times 5=20\\20=20[/tex]

Thus, the point satisfies and it will lie on the line.

(b) The first point is (0,10). Put this point in the equation as,

[tex]2x + 4y=20\\2\times0+4\times 10=20\\40\neq20[/tex]

Thus, the point doesn't satisfy and hence, it will not lie on the line.

(c) The first point is (1,4). Put this point in the equation as,

[tex]2x + 4y=20\\2\times1+4\times 4=20\\18 \neq 20[/tex]

Thus, the point doesn't satisfy and hence, it will not lie on the line.

(d) The first point is (5,0). Put this point in the equation as,

[tex]2x + 4y=20\\2\times5+4\times 0=20\\10 \neq 20[/tex]

Thus, the point doesn't satisfy and hence, it will not lie on the line.

(f) The first point is (10,0). Put this point in the equation as,

[tex]2x + 4y=20\\2\times10+4\times 0=20\\20 =20[/tex]

Thus, the point satisfies and it will lie on the line.

Therefore, points (0,5) and (10,0) will lie on the given line.

Step-by-step explanation:

The formula of an area of a square:

[tex]A=s^2[/tex]

s - side

The formula of a perimeter of a square:

[tex]P=4s[/tex]

s - side

We have a perimeter

[tex]P=60\ in[/tex]

Substitute:

[tex]4s=60[/tex]             divide both sides by 4

[tex]\dfrac{4s}{4}=\dfrac{60}{4}\\\\s=15\ in[/tex]

Put it to the formula of an area of a square:

[tex]A=15^2=225\ in^2[/tex]

Answer: 225 in.²

Step-by-step explanation: First, we want to find the length of one side. Since we know that a square has 4 sides and the perimeter is 60 inches, we can set up the following equation to find the length of one side.

Let's use l as our variable to represent length.

4l = 60

To get l by itself, we need to divide by 4 on the left side of the equation. Since we divided by 4 on the left side, we must also divide by 4 on the right side. On the left side, the 4's cancel and we are left with l. On the right side, we have 60 over 4 which simplifies to 15.

This means that a side of the square is 15 inches.

Now, we are asking ourselves what is the area of a square with a side length of 15 inches.

To find the area of a square, remember that a square is a type of rectangle so we can use the following formula.

Area = length × width

However, since the length and width of a square are always equal, we use a special version of this formula to find the area of a square.

Instead of area = length × width, we say that the area of a square equals side × side or S².

Since the sides of the square each have a length of 15 inches, the area of the square is equal to (15 in.)² or (15 in) (15 in) which equals 225 in.²

Therefore, the area of the square is 225 in.².

Answer:

9 hours at 9 dollars an hour is 81 dollars so therefore he needs to work 9 weeks in order to raise the money.

Step-by-step explanation:

Without the total cost of the car and additional fees, we cannot accurately calculate the number of hours or weeks Ryan needs to work. However, the process involves dividing the total cost by his hourly or weekly wage and interpreting the results.

In order to answer these questions, we first need to know the total cost of the car including the taxes, title, and plates. We are given that Ryan earns $9 per hour and works about 9 hours a week. However, without the total cost of the car and other fees, we cannot accurately calculate how many hours or weeks Ryan needs to work to afford the car.

Part A: Once we have the total cost, we could draw a bar diagram partitioning it into units of $9 (one hour's wage). This would visually represent the number of hours Ryan needs to work.

Part B & C: For these parts, we would also need to know the total cost. Once we have it, we divide the total cost by Ryan's weekly wage ($9/hour x 9 hours = $81/week) to get the number of weeks he needs to work. If the result is a fraction, we would round it up to the next whole number for Part B, as Ryan cannot work a fraction of a week. This provides an estimate. For Part C, we would be more precise by exactly computing the number of weeks and explaining why our solution is reasonable.

Answer:

x = 4

Step-by-step explanation:

Solve the inequality

2x - 3 > 11 - 5x ( add 5x to both sides )

7x - 3 > 11 ( add 3 to both sides )

7x > 14 ( divide both sides by 7 )

x > 2

The only value of x greater than 2 is 4, thus

x = 4 is in the solution set

The value of x that is a solution set to the inequality is: D. 4.

Given the an inequality such as, 2x – 3 > 11 – 5x, solve to isolate x.

2x – 3 > 11 – 5x

Answer:

Step-by-step explanation:

m∠B = 31.7° , a = 21.1 ft , b = 13.0 ft

Step-by-step explanation:

If ABC is a right triangle, where the right angle is B, then

∵ ABC is a right triangle

∵ m∠C = 90°

∴ c is the hypotenuse and a , b are its legs

∵ m∠A = 58.3°

- The sum of the two acute angles in the right triangle = 90°

∴ m∠A + m∠B = 90°

- Substitute the measure of angle A

∴ 58.3 + m∠B = 90

- Subtract 58.3 from both sides

∴ m∠B = 31.7°

∵ sin(A) = [tex]\frac{a}{c}[/tex]

∵ c = 24.8 feet

∴ sin(58.3) = [tex]\frac{a}{24.8}[/tex]

- By using cross multiplication

∴ a = (24.8) × sin(58.3)

∴ a = 21.1 ft

∵ sin(B) = [tex]\frac{b}{c}[/tex]

∵ c = 24.8 feet

∴ sin(31.7) = [tex]\frac{b}{24.8}[/tex]

- By using cross multiplication

∴ b = (24.8) × sin(31.7)

∴ b = 13.0 ft

m∠B = 31.7° , a = 21.1 ft , b = 13.0 ft

Answer:

c. 106 million

Step-by-step explanation:

A = number of people in the sample that use public transportation 5 or more days per week

A = 2,067,153

B = number of people total in the sample

B = 4,295,280

C = proportion of those in the sample that use public transportation 5 or more days per week

C = A/B

C = (2,067,153)/(4,295,280)

C = 0.48126 approximately

Multiply this value by the figure 220 million to compute the estimated number of people who use public transportation 5 or more days per week

C*(220 million) = 0.48126*(220 million) = (0.48126*220) million = 105.8772 million = 106 million

Answer:

The total cost of the bond is none of the given choices.

Step-by-step explanation:

The selling price of a $1000 bond  =   $99.875

The brokerage fee = 5.5 %

Now, 5.5%  of $99.875 =  [tex]\frac{5.5}{100}  \times 99.875 = 5.493[/tex]

So, the brokerage fee = $5.493

Now, to find out the total cost of the bond:

Total Cost  = The selling Price + Brokerage Price

                  = $99.875 + $5.493

                  =  $105.368

or, the total price of the $1000 bond is $ 105.368.

Hence,  the total cost of the bond is none of the given choices.

Answer:

Area of the surface area of the lower half made of exposed granite = 1/4 (Perimeter of the base * Slant length)

Step-by-step explanation:

1. Let's review the data provided to us for solving the question:

Lower half of a square pyramid is made of granite

Top half of a square pyramid is made of limestone

2. Let's explain how we could find the surface area of the exposed granite.

First of all, let's remember what is the area of a square pyramid:

Area of square pyramid = Base area + Surface area of the four sides

Normally, we need to know the length of the square base and the slant length. And now let's replace in the formula:

Area of square pyramid = Length of the side of the square² + 1/2 (4 * Length of the side of the square * Slant length)

For calculating the surface area of the lower half made of exposed granite, we need to don't consider the base area and just the half of the surface area of the four sides, so the formula is:

Area of the surface area of the lower half made of exposed granite = 1/2 [1/2 (4 * Length of the side of the square * Slant length)]

Area of the surface area of the lower half made of exposed granite = 1/4 (4 * Length of the side of the square * Slant length)

Area of the surface area of the lower half made of exposed granite = 1/4 (4 * Length of the side of the square * Slant length)

Area of the surface area of the lower half made of exposed granite = 1/4 (Perimeter of the base * Slant length)

If we want to know the surface area of the lower half made of limestone, we can use the same formula:

Area of the surface area of the lower half made of limestone = 1/4 (Perimeter of the base * Slant length)

Answer:

Find the surface area of the entire square pyramid. Find the surface area of the exposed sides of the square pyramid made from limestone. Subtract the surface area of the square pyramid made from limestone from the surface area of the entire square pyramid.
