1) The expression that represents the total cost of the bouncy house for c children is:Total Cost} = 150 + 2c 2) The total cost for the bouncy house for 15 children is $180.

(1) The expression that represents the total cost of the bouncy house for c children is given by: Total Cost} = 150 + 2c

(2) Given that a total of 15 children attended Sue’s party, including Sue, substitute c with 15 in the expression:

Total Cost} = 150 + 2 * 15

Total Cost} = 150 + 30

Total Cost} = 180

Therefore, the total cost for the bouncy house for 15 children is $180.

Answer:

15-x+4=-59

Step-by-step explanation:

The equation of 15 subtracted from the product of a number and 4 is -59 is 4x - 15 = -59.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that 15 is subtracted from the product of a number and 4 is -59. The expression will be written by assuming that the unknown number is x.

The expression is written as,

4x - 15 = -59

Final answer:

The Great Wall of China was approximately 3,000 miles long.

Explanation:

The Great Wall of China was 10,000 li long. In this case, li is a unit of measure. We are told that 2 li is approximately equal to 0.6 miles. To find how many miles the Great Wall is, we can set up a proportion:

2 li = 0.6 miles
10,000 li = x miles

To solve for x, we can cross multiply and divide:

10,000 li * 0.6 miles = 2 li * x miles
6,000 miles = 2x
x = 6,000 / 2
x = 3,000 miles

Therefore, Shih Huangdi's Great Wall of China was approximately 3,000 miles long.

The gardener's expression correctly calculates the area of the entire garden after extension, not just the extension itself. The error was in misinterpreting the question and focusing solely on the extension, leading to the incorrect answer of 13 square feet.

Expanding the expression: 6(x + 7) = 6x + 42. This represents the total area of the garden after extending its length by 7 feet.

Error analysis: The gardener likely assumed they needed to calculate the area added by the extension. This could be due to:

Misunderstanding the question and focusing on the 7-foot extension instead of the total area change.

Mistakenly interpreting "area of the extension" as the area of the rectangle formed only by the additional 7-foot length and the original width.

Therefore, while the expression itself is correct, the gardener misinterpreted the question and made an error in interpreting what "area of the extension" referred to.

Answer:

Step-by-step explanation:

since both equations are equal to the same thing, y, they are therefore equal to each other

so:

[tex]3x-5=2x-6\\x-5=-6\\x=-1\\[/tex]

substitute x, -1,  into either equation to solve for y

[tex]y=3(-1)-5\\y=-3-5\\y=-8[/tex]

or

[tex]y=2(-1)-6\\y=-2-6\\y=-8[/tex]

Therefore, the solution is (-1,-8)

After solving the equations by substitution method the value of x is -1 and the value of y is -8. Hence, option C is correct.

Equations are mathematical expressions that have two algebras on either side of an equal (=) sign. The expressions on the left and right are shown to be equal to one another, demonstrating this relationship. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation.

As per the given equation from the question,

y = 3x -5   (i)

y = 2x - 6  (ii)

Compare both equations,

3x - 5 = 2x - 6

3x -2x = -6 + 5

x = -1

Substitute x = -1 in equation (i)

y = 3 (-1) - 5

y = -8.

Therefore, both the values are (-1, -8).

Comparing a hatchling turtle's shell of 1-inch diameter to a 4-inch diameter shell reveals that the volume increases by a factor of about 64, while the surface area only increases by about 16. This difference is due to the way volume and surface area are calculated, with the radius being cubed in the volume formula and squared in the surface area formula.

The volume of a sphere (like the turtle's shell) is given by the formula: V = (4/3) * π * r³, and the surface area by A = 4 * π * r², where r is its radius. If a hatchling turtle's shell has a 1-inch diameter, it has a radius of 0.5-inches. If as the turtle grows, its diameter expands to 4-inches, then the radius will be 2-inches. As the radius in each formula is cubed in the volume formula and squared in the surface area formula, the volume will increase far more rapidly than the surface area.

For the smaller turtle, V = (4/3)*π*(0.5)³ = 0.52 cubic inches and A = 4*π*(0.5)² = 3.14 square inches. For the larger turtle, V = (4/3)*π*(2)³ = 33.51 cubic inches and A = 4*π*(2)² = 50.27 square inches. Comparing, the volume increases by a factor of 64 (33.51/0.52) whereas the surface area increases by a factor of roughly 16 (50.27/3.14). This shows that although the turtle's shell maintains the same shape as it grows, the volume increases significantly more than the surface area.

The scale factor from figure a to figure b would be 1/16 i believe.

Correct me if im wrong

The scale factor of figure A to figure B is 5/9.

In the given figure, A and B are similar triangles.

A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller).

The basic formula to find the scale factor of a figure is expressed as,

Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape.

Here, 20/36

= 5/9

= 14/25.2

= 2/3.6

= 5/9

Hence, the scale factor of figure A to figure B is 5/9.

2 more than triple the number can be expressed as 3x + 2. We want this expression to equal 10, so we can set up the equation as 3x + 2 = 10.

To solve the equation, '2 more than triple a number is 10', we can first translate the sentence into an equation.

Let's assume the number is represented by x.

Triple the number would be 3x. And 2 more than triple the number can be expressed as 3x + 2.

We want this expression to equal 10, so we can set up the equation as follows:

3x + 2 = 10

Now, we can solve for x by isolating it on one side of the equation.

Subtracting 2 from both sides, we get:

3x = 8

Finally, divide both sides by 3 to solve for x:

x = 8/3
