Step-by-step explanation:

out of the 21 students, 8 do not play neither basketball nor baseball.

so, 13 students play at least one of these games.

10 play basketball, and 9 play baseball. that would be 19 together. but we have only 13 players.

that means 6 students (19 - 13) must play both games.

remember, a probability is always

desired cases / possible cases

so, when we are looking for the students, who play both games, we have 6 desired cases out of a total of 21.

and the probability to pick one of them is therefore

6/21 = 2/7 = 0.285714286...

Based on the calculations, the total distance of Mara's run is equal to: C. 12 km.

In order to determine the total distance of Mara's run, we would solve for the length of the hypotenuse by applying Pythagorean's theorem and then add it to the other distances.

Mathematically, Pythagorean's theorem is given by this formula:

c² = a² + b²

Where:

Substituting the given parameters into the formula, we have;

c² = 3² + 4²

c² = 9 + 16

c = √25

c = 5 km.

Now, we can determine the total distance of Mara's run:

Total distance = 3 + 4 + 5

Total distance = 12 km.

The expression of Volume in cubic meter  [tex]\frac{1}{3}[/tex] (8)(6)(6)+(8)(6)(4)

The correct option is (1)

Volume can also be defined as the amount of space occupied by a 3-dimensional object. The volume of a solid like a cube or a cuboid is measured by counting the number of unit cubes it contains.

Volume will be,

V= Volume of rectangular pyramid + Volume of cuboid

Volume of rectangular pyramid= [tex]\frac{1}{3}[/tex] * base area* height

                                                   = [tex]\frac{1}{3}[/tex] * 6*8*(10-4)

                                                   =[tex]\frac{1}{3}[/tex] * 6*8*6

Volume of cuboid= l*b*h

                              = 4*6*8

So, Volume   =[tex]\frac{1}{3}[/tex] * 6*8*6 + 4*6*8

                     = [tex]\frac{1}{3}[/tex] (8)(6)(6)+(8)(6)(4)

Answer:

B. supplementary angles

Step-by-step explanation:

The area of the considered trapezoid  PQRS in simplest radical form is given by: Option c: 256 + 128√3 (in sq. units)

The area of a trapezoid is the half of the product of sum of its parallel sides to the height of that trapezoid (the distance between those parallel sides).

Thus, if we have:

Length of its parallel sides = 'a' and 'b' units respectively

Perpendicular distance between its parallel sides = 'h' units,

Then, we get:

[tex]A = \dfrac{1}{2}\times(a+b) \times h \: \rm unit^2[/tex]

Consider the figure attached below, which is a bit more labeled figure of the given trapezoid.

We constructed PA perpendicular to the level of SR, and therefore, as SR is parallel to PQ, we have PA perpendicular to PQ too.

Similarly, QB is constructed perpendicular to both PQ and SR.

Thus, for PQBA, all pair of adjacent sides are perpendicular to each other, therefore its a rectangle.

Sum of parallel sides = Length of PQ + Length of SR

= 24 + |SR| = 24 + |SB| + |BR| = 24 + |AS| - |AS| + |SB| |+ |BR|

= 24 + |AS| + |SB| + |BR| - |AS| = 24 + |AB| + |BR| - |AS|

Due to PABQ being a rectangle (its four sides are such that adjacent sides are perpendicular to each other), we have |PQ| = |AB| = 24 units.

Thus, we get:

Sum of parallel sides = 24 + |AB| + |BR| - |AS| = 48 + |BR| - |AS|

Perpendicular distance between its parallel sides = |PA| = |QB|

Thus, we need to find the values of 3 line segments, which are:

|BR|, |AS|, and |PA| (instead of |PA|, we can find |QB| too, since both are of same length).

From the perpective of angle R(interior) in right triangle RBQ, we know the side RQ's length (32 units), and want length of BR.

Thus, its hypotenuse and base from the perspective of angle R (interior).

Thus, we can use cosine ratio or secant ratio. Let we use cosine ratio.

Then, we get:
[tex]\cos(30^\circ) = \dfrac{|BR|}{|RQ|} \\\\|BR| = 32 \times \cos(30^\circ) = 32 \times \dfrac{\sqrt{3}}{2} = 16\sqrt{3}\: \rm units[/tex]

For the same triangle as in case 1 (ie RBQ), but now taking the sine ratio, we get:

[tex]\sin(30^\circ) = \dfrac{|BQ|}{|RQ|} \\\\|BQ| = 32 \times \sin(30^\circ) = 16 \: \rm units[/tex]

This is same as |PA| because of PQBA being a rectangle.

The angle PSA is supplement of angle PSR as both joined make a straight line ASR. Thus, we get:
[tex]m\angle PSA + m\angle PSR = 180^\circ\\m\angle PSA = 180^\circ-135^\circ = 45^\circ[/tex]

Thus, for the triangle PSA, similar to the first case or second case, but now using tangent ratio as we've got |PA| = |QB| = 16 units, we get:

[tex]\tan(m\angle PSA) = \dfrac{|PA|}{|AS|}\\\tan(45^\circ) = \dfrac{|PA|}{|AS|} \\\\|AS| = 1 \times 16 = 16 \: \rm units[/tex]

Thus, we get:

Sum of parallel sides = 48 + |BR| - |AS| = 48 + 16√3 - 16 = 32 + 16√3 units

Perpendicular distance between its parallel sides = |PA| = |QB| = 16 units.

Thus, Area of the trapezoid PQRS is evaluated as:

[tex]A = \dfrac{1}{2} \times \text{Sum of parallel sides} \times \text{Distance between those sides}\\A =\dfrac{1}{2} \times (32 + 16\sqrt{3}) \times 16 \\\\A = 256 + 128\sqrt{3} \: \rm unit^2[/tex]

Thus, the area of the considered trapezoid  PQRS in simplest radical form is given by: Option c: 256 + 128√3 (in sq. units)

Any smooth curve connecting two points is called an arc. The arc length is the measurement of how long an arc is. The length of an arc is given by the formula,

[tex]\rm{ Length\ of\ an\ Arc = 2\times \pi \times(radius)\times\dfrac{\theta}{360} = 2\pi r \times \dfrac{\theta}{2\pi}[/tex]

where

θ is the angle, that arc creates at the centre of the circle in degree.

If the central angle has a measure of π/2(90°), then the length of the arc will be one-fourth of the total, while if the measure of the angle is π(180°), then the length of the arc will be half of the total.

Similarly, if the measure of the angle is 3π/4, then the length of the arc will be three-fourth of the total, while if the measure of the angle is 2π(360°), then the length of the arc will be 2πr.

Step-by-step explanation:

What we know,

3 hamburgers = $12.99

Coleman wants to know how much would he have to pay for 10 hamburgers,

In order to find out how much 10 hamburgers cost, you need to find out how much 1 hamburger costs,

To find how much 1 hamburger costs divide 12.99 by 3,

12.99/3

= 4.33

Now we know that 1 hamburger cost $4.33,

Now time to find out how much 10 hamburgers cost,

Multiply 4.33 by 10,

4.33 × 10

= 43.30

Therefore it cost $43.30 for 10 hamburgers.

The game is an illustration of probability, and the probability that each player wins is 1/12

From the question, we have the following parameters:

Number of a pair of numbers = 3

A die has 6 possible outcomes.

So, the probability of getting the first pair is:

P1 = 1/6

The probability of getting the second pair is:

P2 = 1/6

The probability of getting the first and the second pairs is

P = 1/6 * 1/6

Evaluate

P = 1/36

There are three pairs of numbers in total.

So, the probability of winning is:

P(Win) = 3 * 1/36

Evaluate

P(Win) = 1/12

Hence, the probability that each player wins is 1/12

The length which result in a ratio closest to the golden ratio is equal to  7.5 inches and 4.5 inches. Option C is correct.

The line segment is made with two end points. Length of a line segment is the distance of both the ends of it.

A 12 inch line segment is divided into two parts. Suppose the line segment is AC which is divided into AB and BC parts. Thus,

AB+BC=AC

AB+BC=12                   ....1

The value of golden ratio is equal to 1.618. It can also be given as (1+√5)/2. The ratio of both segment is equal to golden ratio. Thus

[tex]\dfrac{AB}{BC}=\dfrac{AC}{AB}=\dfrac{1+\sqrt{5}}{2}\\\dfrac{12}{AB}=1.618\\AB=7.4166 \rm\; in[/tex]
