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.

The front wheel turns around approximately 300 times.

To determine how many times Gia's bicycle wheel turns around during her 1,884 feet ride, we need to calculate the circumference of the wheel and then divide the total distance traveled by the circumference.

The diameter of the wheel is 24 inches. To find the circumference (C), we use the formula C = pi x d, where d is the diameter, and (pi) is approximately 3.14159.

C = 3.14159 x 24 inches = 75.39816 inches.

Next, we need to convert the distance Gia rode her bike from feet to inches because the circumference is in inches. There are 12 inches in a foot, so

1,884 feet x 12 inches/foot = 22,608 inches.

Now we divide the total distance traveled in inches by the circumference of the wheel to find out how many full revolutions there are:

22,608 inches / 75.39816 inches/revolution ≈ 300 revolutions.

To the nearest whole number, Gia's front bicycle wheel turns all the way around 300 times.

The ratio of boys to girls will be 15 : 13.

There are 28 students in all.

The fraction of the students are girls will be 13/28.

A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities. And, Total quantity gives after combine as x + y.

Given that;

A class contains 13 girls and 15 boys.

Now,

Since, A class contains 13 girls and 15 boys.

Hence, Number of total students = 13 + 15

                                                   = 28

So, The ratio of boys to girls = Number of boys : Number of girls

                                             = 15 : 13

Hence, Number of total students = 13 + 15

                                                   = 28

And, The fraction of the students are girls is;

= Number of girls / Number of students

= 13 / 28

Thus, The ratio of boys to girls = 15 : 13.

Total number of students = 28

And, The fraction of the students are girls = 13/28.

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:

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.

Answer:

17=p+8

Step-by-step explanation:

Start by setting the equation equal to 17 on either the right or left side. Now, on the opposite side of the equation read out what the question is saying.

"8 more than a number (p)" the variable would be p, and 8 more than p is 17. Now that you have that in mind, write 17 is equal to p plus 8.

17=p+8

If the question asks you to solve this equation for p, subtract 8 from both sides to get 9 for p.

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

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.

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

Answer:  37.5 is 5% of 57.6923077

Step-by-step explanation:

The number where 75% of it equals 37.5 is 50.

To find the number, we can set up an equation based on the given information: 75% of a certain number is equal to 37.5. Mathematically, this can be represented as:

0.75x = 37.5

To isolate x, we can divide both sides of the equation by 0.75:

x = 37.5 / 0.75

Evaluating the division:

x = 50

Therefore, the number we are looking for is 50.

The equation 0.75x = 37.5 states that 75% (or 0.75 as a decimal) of a certain number x is equal to 37.5. By dividing both sides of the equation by 0.75, we "undo" the multiplication and solve for x. Dividing 37.5 by 0.75 gives us the value of 50.

To check our solution, we can substitute x = 50 back into the original equation:

0.75 x 50 = 37.5

37.5 = 37.5

The equation holds true, confirming that 50 is indeed the number where 75% of it equals 37.5.
