Answer:

The coordinates of the mid-point of JL are (-5 , 2)

Step-by-step explanation:

If point (x , y) is the mid-point of a segment whose end-points are [tex](x_{1},y_{1})[/tex] and [tex](x_{2},y_{2})[/tex], then [tex]x=\frac{x_{1}+x_{2}}{2}[/tex] and  [tex]y=\frac{y_{1}+y_{2}}{2}[/tex]

∵ JL is a segment

∵ The coordinates of J are (-6 , 1)

∴  [tex]x_{1}[/tex] = -6 and  [tex]y_{1}[/tex] = 1

∵ The coordinates of L are (-4 , 3)

∴  [tex]x_{2}[/tex] = -4 and  [tex]y_{2}[/tex] = 3

Lets use the rule above to find the mid-point of JL

∵ [tex]x=\frac{-6+-4}{2}=\frac{-10}{2}[/tex]

∴ x = -5

∴ The x-coordinate of the mid-point is -5

∵ [tex]y=\frac{1+3}{2}=\frac{4}{2}[/tex]

∴ y = 2

∴ The y-coordinate of the mid-point is 2

∴ The coordinates of the mid-point of JL are (-5 , 2)

Final answer:

The coordinates of the midpoint of the segment with endpoints J(-6, 1) and L(-4,3) are obtained by averaging the x and y coordinates of the endpoints, resulting in (-5, 2).

Explanation:

To find the coordinates of the midpoint of a segment with endpoints J(-6, 1) and L(-4,3), you use the midpoint formula which is ((x1 + x2)/2, (y1 + y2)/2). In this case, x1 is -6, x2 is -4, y1 is 1, and y2 is 3. Plugging these into the formula, we get the midpoint coordinates ((-6 - 4)/2, (1 + 3)/2) which simplifies to (-5, 2). Therefore, the midpoint of JL is at the coordinates (-5, 2).

Answer:

16 inches

Step-by-step explanation:

The perimeter of the tile is 16 inches. The perimeter of a shape is the total length of all of its sides added together.

In this case, the tile has two sides that are 6 inches long and two sides that are 2 inches long.

To find the perimeter, we can add all of the side lengths together:

Perimeter = 6 inches + 6 inches + 2 inches + 2 inches

Perimeter = 16 inches

Therefore, the perimeter of the tile is 16 inches.

Answer:

A

Step-by-step explanation:

To find the number of adults and children admitted to the movie theater, we set up two equations based on the admission costs and total number of attendees. Solving these equations revealed that there were 450 adults and 225 children.

The question involves a system of equations where we are required to determine the number of adults and children who were admitted to the movie theater given the total revenue and total number of attendees.

Let's denote the number of adults by A and the number of children by C. Given the price of admission is $7 for an adult and $5 for a child, we can represent the total revenue with the equation:

7A + 5C = 4275
Also, considering the total number of people is 675, we have another equation:

A + C = 675

To solve these equations, we'll use the substitution or elimination method:

Therefore, there were 450 adults and 225 children admitted to the movie theater that day.

Answer: option c

Step-by-step explanation:

margin of error = critical value × s/√n

Where s = sample standard deviation = 0.58, n = 53

The critical value = 1.96 ( this is the critical value for a two test test corresponding to a level of significance of 5%)

By substituting the parameters, we have that

Margin of error = 1.96×0.58/√53

Margin of error = 1.96 × 0.0796

Margin of error = 0.156 ~ 0.16

One sample cup will hold 11.51 ounces of fluid.

Step-by-step explanation:

Diameter of cone shaped cup = 4 inches

Radius = [tex]\frac{Diameter}{2}=\frac{4}{2}=2\ inches[/tex]

Height of cup = 5 inches

Volume of cone = [tex]\pi r^2 \frac{h}{3}[/tex]

Putting values

Volume of cone = [tex]3.14*(2)^2*\frac{5}{3}\\[/tex]

Volume of cone = [tex]3.14*4*\frac{5}{3}=\frac{62.8}{3}[/tex]

Volume of cone = 20.93 inches cubed

Amount of fluid in one cubic inch = 0.55 ounces

Amount of fluid in 20.93 cubic inches = 0.55*20.93 = 11.51 ounces

One sample cup will hold 11.51 ounces of fluid.

Answer:

B

Step-by-step explanation:

If it is inscribed in the circle that means all four corners of the square are touching the circle

so therefore the diagonal of the square is the diameter of the circle

the side lengths of the square as you know is 7 units ([tex]\sqrt{49[/tex]) the length of the diagonal is [tex]7\sqrt{2}[/tex] heres how I know

If you cut the square in half through the centre diagonally you will get a right  isosceles triangle, using the pythagorus theorum

[tex]7^2+7^2=C^2\\49+49=C^2\\98=C^2\\\sqrt{98}=C\\C=7\sqrt{x}[/tex]

Now we have the diameter

it's just half of that, so the answer is B

For a square inscribed in a circle, the length of the diagonal of the square equals the diameter of the circle. Given the area of the square is 49 units, the length of a side is 7 units, and thus the diagonal (or diameter of the circle) is 7√2 units. Therefore, the radius of the circle is half of the diameter, which is (7√2)/2 units.

In this question, we need to determine the radius of a circle in which a square is inscribed. The square has an area of 49 square units. In a square inscribed in a circle, the diameter of the circle is equal to the diagonal of the square. Thus, if 'a' is the length of a side of the square, the length of the diagonal, which is the diameter of the circle, is 'a√2'.

Given that the area of the square is 49 units, 'a^2=49' or 'a=7' units. Therefore, 'a√2' = '7√2' units. As this is the diameter, the radius of the circle is half of the diameter thus, it equals '(7√2)/2' units. Which means option b '(7√2)/2' units is the correct answer.

The sum of the first 100 even natural numbers will be 10,100.

Let a₁ be the first term, L be the last term, n be the number of terms, and d be a common difference.

Then the sum of the arithmetic sequence will be

S = (n / 2)[a₁ + L]

S = (n/2) [2a + (n − 1) d]

The arithmetic sequence is given below.

2, 4, 6, 8, 10, .....

The first term is 2 and the common difference is 2. Then the sum of the first 100 even natural numbers will be

S = (100/2) [2 x 2 + (100 − 1) x 2]

S = 50 [4 + 99 x 2]

S = 50 [4 + 198]

S = 50 [202]

S = 10,100

The sum of the first 100 even natural numbers will be 10,100.

Answer:

3 apples per $ is the greatest unit rate when someone buy 12 apples for $4, because we are able buy more apples with this rate for the same price.

Step-by-step explanation:

As we know that unit rate can be calculated by dividing the two quantities having different units.

For example, Madrid has been champions 10 times in 30 seasons,

i.e. 10 champions / 30 seasons = 0.33 champions per season

and

Barcelona has been champions 5 times in 30 seasons.

i.e.  5 champions / 30 seasons = 0.16 champions per season

Thus, the champion rate for Real Madrid is greater than the champion rate for Barcelona. It means, Real Madrid has been a better team.

Now, let us check and answer the question.

       12 apples / $4 = 3 apples per $

       21 apples / $8 = 2.62 apples per $

       35 apples / $14 = 2.5 apples per $

       45 apples / $16 = 2.81 apples per $

From the above calculations and observation, we can conclude that 3 apples per $ is the greatest unit rate when someone buy 12 apples for $4.

This unit rate is the greatest because we are able buy more apples with this rate for the same price.

In other words, the rate is cheaper than the unit rate of the rest, because can buy more apples with this rate for the same price.

Option B: 13.9 is the value of y

Explanation:

Given triangle is a right angled triangle.

The legs of the triangle are 8 and y.

The hypotenuse of the triangle is x.

And the angle opposite to y is 60°

We need to determine the value of y.

Let us find the value of y using the tangent formula.

The formula for tan is given by

[tex]tan \ \theta=\frac{opp}{adj}[/tex]

Since, we know that [tex]\theta = 60^{\circ[/tex] , [tex]opp=y[/tex] and [tex]adj=8[/tex]

Substituting these values in the formula, we get,

[tex]tan \ 60^{\circ}=\frac{y}{8}[/tex]

Multiplying both sides by 8, we have,

[tex]8\times tan \ 60^{\circ}=y[/tex]

Substituting the value of [tex]\tan 60^{\circ}[/tex] , we get,

[tex]8\times 1.732=y[/tex]

Simplifying, we have,

[tex]13.856=y[/tex]

Rounding off, we get,

[tex]13.9=y[/tex]

Thus, the value of y is 13.9

Hence, Option B is the correct answer.

Answer:

$467.05

Step-by-step explanation:

The price is $562

First, 20% off of that:

562 - 20% of 562 = 562 - 0.2(562) = $449.60

Second, he has to pay 6% tax on this amount, so:

6% = 6/100 = 0.06

449.60 + 0.06*449.60 = $476.58

He won't be paying this amount, because paying through credit card will give him 2% discount on this, so:

476.58 - 0.02(476.58) = $467.05

Final Price: $467.05
