if each side of a square is the same length then yes my answer is correct

Final answer:

To find the perimeter of the square with a side length of [tex]2\frac{1}{2}[/tex] yards, the side length is converted to a decimal and multiplied by 4, resulting in a perimeter of 10 yards.

Explanation:

The student's question is about finding the perimeter of a square when given the length of one side, which is [tex]2\frac{1}{2}[/tex] yards.

Since a square has four equal sides, the perimeter (P) of a square is calculated by multiplying the length of one side (s) by 4, which can be expressed as P = 4s.

In this case, if we convert [tex]2\frac{1}{2}[/tex] yards to a decimal, we get 2.5 yards.

Therefore, the perimeter of the square is 4 × 2.5 yards, which equals 10 yards.

Step-by-step explanation:

Approximately, the quantity of water it will take to fill this tank is equal to 39,413 cubic feet.

Given the following data:

Radius of cylinder = 28 feet.

Height of cylinder = 16 feet.

Mathematically, the volume of a cylinder is calculated by using this formula:

V = πr²h

Where:

Substituting the given parameters into the formula, we have;

V = 3.142 × 28² × 16

V = 39,413.248 ≈ 39,413 cubic feet.

For the cover size, we have:

Area = πr²

Area = 3.142 × 28²

Area = 2,463.328 ≈ 2,463 ft².

Answer:

No, images are not same as  their dimensions are different although two sides in each of the two triangles are equal.

Step-by-step explanation:

Given: images of two isosceles triangles.

To check: if images are the same

Solution:

A triangle is a polygon made up of three sides.

An isosceles triangle is a triangle in which two sides are equal. Also, in an isosceles triangle, angles opposite to equal sides are equal.

The given images of two isosceles triangles A and B are not the same as their dimensions are different although two sides in each of the two triangles are equal.

Answer:

B: Science

Step-by-step explanation:

The reason B is correct is because 0.016 is lower than all the other possibility. A has no math to compare, but the others do, making it easier to determine the correct answer.

Answer:c

Step-by-step explanation:

Answer: A is the answer

Step-by-step explanation:

Answer:

equidistant from point F and line d: (0, 3); (6, 6) and (-6, 6)

not equidistant from point F and line d: (3, 0); (3, 5) and (-2, 2)

Step-by-step explanation:

Point (0, 3)

Distance from point (0, 6) = 3

Distance from line d = 3

Point (6, 6)

Distance from point (0, 6) = 6

Distance from line d = 6

Point (3, 0)

Distance from point (0, 6) = √[(3 - 0)² + (0 - 6)²] = √45

Distance from line d = 0

Point (3, 5)

Distance from point (0, 6) = √[(3 - 0)² + (5 - 6)²] = √10

Distance from line d = 5

Point (-2, 2)

Distance from point (0, 6) = √[(-2 - 0)² + (2 - 6)²] = √20

Distance from line d = 2

Point (-6, 6)

Distance from point (0, 6) = 6

Distance from line d = 6

Step-by-step explanation:

1/4y+3/4(y-8)

1/4y+3/4y-6

1y-6

Just simplify the equation by distributing 3/4 to y and -8 then combine like terms

Answer:

A

Step-by-step explanation:

Given

f(x) = - 4(x + 7)² - 6 ← expand factor using FOIL

     = - 4(x² + 14x + 49) - 6 ← distribute parenthesis by - 4

    = - 4x² - 56x - 196 - 6 ← collect like terms

    = - 4x² - 56x - 202 → A

The equivalent function is [tex]f(x)=-4x^{2} -56x-202[/tex]

Option A is correct.

The given function is,

                        [tex]f(x)=-4(x+7)^{2}-6[/tex]

We have to expand above function.

                    [tex]f(x)=-4(x+7)^{2}-6\\\\f(x)=-4(x^{2} +14x+49)-6\\\\f(x)=-4x^{2} -56x-196-6\\\\f(x)=-4x^{2} -56x-202[/tex]

Thus, the equivalent function is [tex]f(x)=-4x^{2} -56x-202[/tex]

Answer:

it is true on quiz 7.1.2 exam sem 1

Step-by-step explanation:

a. The mode for away goals is the 2nd quarter.

b. The mean number of goals per game is 4.8.

c. There were 4 more home goals scored than away goals in total across 10 games, with a total of 26 home goals and 22 away goals.

a. To find the mode for away goals, we need to determine which quarter had the most frequent number of away goals. Let's count the away goals for each quarter:

1st quarter: 2 away goals

2nd quarter: 9 away goals

3rd quarter: 7 away goals

4th quarter: 4 away goals

The 2nd quarter has the highest number of away goals, so the mode for away goals is the 2nd quarter.

b. To find the mean number of goals per game, we'll sum the total number of goals and then divide by the number of games:

Total number of goals = (5 + 4 + 8 + 9) + (2 + 9 + 7 + 4) = 48 goals

Number of games = 10

Mean number of goals per game = Total number of goals / Number of games = 48 goals / 10 games = 4.8 goals per game.

c. To find how many more home goals were scored than away goals in total, we'll calculate the difference in the total number of home goals and away goals:

Total home goals = 5 + 4 + 8 + 9 = 26 goals

Total away goals = 2 + 9 + 7 + 4 = 22 goals

Difference = Total home goals - Total away goals = 26 goals - 22 goals = 4 goals

In total, 4 more home goals were scored than away goals.

Answer:

False

Step-by-step explanation:

Parallel lines are lines that never intersect.  If the line changes slightly, the lines will intersect. This doesn't mean that it's perpendicular

Perpendicular lines are lines that intersect in such a way that the lines form 90 degree angles.

The statement is false. Non-parallel lines are not necessarily perpendicular; they can intersect at any angle other than right angles.

The statement 'If a pair of lines is not parallel, it must be perpendicular' is False. Not all non-parallel lines are perpendicular. Perpendicular lines are a specific case of non-parallel lines where they meet at right angles (90 degrees). Non-parallel lines that are not perpendicular to each other may intersect at any other angle, which could be acute or obtuse but not 90 degrees.

Theorem 10 supports this by stating that 'If two lines cut a third at the same angle, that is, so that corresponding angles are equal, a line can be drawn that is perpendicular to both'. Theorem 14 also relates as it informs 'If a line is perpendicular to two intersecting lines at their intersection, it is perpendicular to all lines of their plane passing through this point'. However, non-parallel lines that do not satisfy these conditions are simply intersecting lines at some angle other than 90 degrees.

The measure of arc xz is 106 degrees.

A small arc is one with a measure of fewer than 180 degrees. A major arc is one with a measure greater than 180 degrees. A semicircle is an arc that divides a circle in half and has a measure of 180 degrees.

An arc is a continuous segment of a circle. There are two sections, one of which is larger than the other. The major arc is the larger one, and the minor arc is the smaller one.

Given:

From diagram, m ∠xz = 254 degrees.

We know that whole circle = 360 degrees

So, measure of arc XZ = 360 - 254

                                      = 106

Hence, the measure of arc xz is 106 degrees.

The graph of a linear function C(d) will shift 20 units left side if the total cost C (in dollars) to rent a 14-foot by 20-foot canopy for d days is function C(d) = 15d + 30.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that:

The total cost C (in dollars) to rent a 14-foot by 20-foot canopy for d days is given by the function:

C(d) = 15d + 30

The charge per day is $15. The setup fee increases by $20.

The new total cost T is given by the function

T(d) = C(d) + 20

Plug C(d) = 15d + 30 in the above function:

T(d) = 15d + 30 + 20

T(d) = 15d + 50

The graph of a linear function C(d) will shift 20 units left side.

Thus, the graph of a linear function C(d) will shift 20 units left side if the total cost C (in dollars) to rent a 14-foot by 20-foot canopy for d days is function C(d) = 15d + 30.

Answer:

5

Step-by-step explanation:

To solve a problem with negatives, we use the following rule.

If it is like

x+(-y), it is equivalent to x-y

If the equation is like

(-x)-(-y), it is equivalent to (-x)+y

So,

5+(-11)=5-11=-6

(-6)-(-11)=(-6)+11=5

Your answer is 5.

By setting up a system of linear equations using the given relationships and solving for Fifi's weight, we find that Fifi weighs 11 pounds.

The question involves solving a system of linear equations to find the weight of Fifi. We are given three pieces of information:

Let's denote Fifi's weight as F, Rover's weight as R, and Fido's weight as D. Based on the information provided, we can write the following equations:

To find Fifi's weight, we need to substitute the first two equations into the third one:
