In the game Yahtzee, players roll five dice. There are 13 rounds per game. In each round, each player can roll the dice up to three times. In a player's first roll of each round, he or she rolls all five dice. The second and third rolls, the player can choose to roll any subset of the dice again (any or all the dice). Yahtzee is a bit like poker with dice. An especially valuable roll is 5 of a kind (all 5 dice show the same number of spots), called a Yahtzee. The next two questions are about Yahtzee. Problem 3 The chance of rolling a Yahtzee (5 of a kind) on the first roll of a turn is closest to

1.Crackers--->1g fiber....2g protein

2.Cookies--->1g fiber....1g protein

3.Nuts--->3g fiber....4g protein

-3 packaged of crackers

-2 packaged of cookies

-1 package of nuts

3g+2g+3g=8g fiber

6g+2g+4g=12g protein

Answer:

3 packages of crackers

, 2 packages of cookies

,  1 package of nuts  

Step-by-step explanation:

Types of packaged snacks :

Crackers

Quantity of fibre = 1 gram

Quantity of protein = 2 grams

Cookies

Quantity of fibre = 1 gram

Quantity of protein = 1 gram

Nuts

Quantity of fibre = 3 grams

Quantity of protein = 4 grams

Required quantity of fibre = 8 grams

Required quantity of protein = 12 grams

To find : Number of packages of each snack that he can eat to obtain his goal

Now 3 packages of crackers  contain 3×1=3 grams of fiber and 3×2=6 grams of proteins .

2 packages of cookies  contain 2×1=2 grams of fiber and 2×1=2 grams of proteins .

1 package of nuts  contain 3×1=3 grams of fiber and 1×4=4 grams of proteins

So, total quantity of fibres that he get from three types of packaged snacks = 3g+2g+3g = 8g fiber

Total quantity of protein that he get from three types of packaged snacks  =

6g+2g+4g = 12g proteins

Your answer is D. 36 - 8i

The answer is:

The father's step is 80 cm

The son's step is 60 cm.

To solve the problem, we need to write equations in order to create a relation between the father's and son's steps, and the distance covered by them.

We know thay they covered 240 meters, and the father's step is 20 cm  (0.2m)greater than his son's step, so, we can write the following relation:

[tex]NumberOfSteps_{Son}=\frac{240m}{x}[/tex]

and,

[tex]NumberOfSteps_{Father}=\frac{240m}{x+0.2m}[/tex]

Now, if the know that the father made 100 fewer steps than his son, we have:

[tex]NumberOfSteps_{Son}-100=\frac{240m}{x+0.2m}[/tex]

Then, substituting the first equation into the second equation, we have:

[tex]\frac{240m}{x}-\frac{240m}{x+0.2m}=100\\\\\frac{240m(x+0.2m)-240mx}{x(x+0.2m)}=100\\\\240mx+0.2m*240m-240mx=(x)(x+0.2m)*100\\\\48m^{2}=100*(x^{2}+0.2mx)=100x^{2} +20mx\\\\48m^{2}=100x^{2}+20mx\\\\100x^{2}+20mx-48m^{2}[/tex]

We have a quadratic equation:

[tex]100x^{2}+20mx-48m^{2}=0[/tex]

Where,

[tex]a=100\\b=20\\c=-48[/tex]

So, solving it applying the quadratic formula, we have:

[tex]\frac{-b+-\sqrt{b^{2} -4ac} }{2a}[/tex]

[tex]\frac{-20+-\sqrt{20^{2} -4*100*-48} }{2*100}=\frac{-20+-\sqrt{400+19200} }{200}\\\\\frac{-20+-\sqrt{400+19200} }{200}=\frac{-20+-\sqrt{19600} }{200}\\\\\frac{-20+-\sqrt{19600} }{200}=\frac{-20+-(140)}{200}\\\\x_{1}=\frac{-20+140}{200}=0.6\\\\x_{2}=\frac{-20-140}{200}=-0.8[/tex]

Then, since distance cannot be negative, we need to take the positive value, so, the son's step is 0.6m or 60 cm.

Now, calculating the father's step, we have:

[tex]FatherStep=SonStep+20cm\\\\FatherStep=60cm+20cm=80cm[/tex]

Hence, we have that the father's step is 80 cm.

Have a nice day!

The distance of the father and son will be 80cm and 60cm respectively.

The number of son's step will be:

= 240/x

The number or father's step will be:

= 240/x + 0.2

Solving further, we'll have 100x² - 20mx - 48m² and using quadratic formula, this will be x1 = 0.6 and x2 = -0.8.

The son's step will be:

= 0.6 × 100 = 60cm

The father's step will be:

= 60cm + 20cm = 80cm

Answer:

an area

Step-by-step explanation:

A two-dimensional (2D) figure is like drawing on a sheet of paper. It has some width and some length, but no height.

So, you cannot calculate its volume, since it has only 2 dimensions, a volume requires 3 dimensions.

The only spacial measure you can do on a two-dimensional figure is its area (basically length * width, if we talk about a rectangle, other forms have different calculation methods).

Answer:

D' ..................> (-2,2)

C'' .................> (3,-1)

A''' ................> (4,-2)

B'' .................> (4,2)

Step-by-step explanation:

Before we begin, we should remember the rotation rules:

1- Rotation 90° clockwise:

Coordinates (x,y) become (y,-x)

2- Rotation 90° counter clockwise:

Coordinates (x,y) become (-y,x)

3- Rotation 180° clockwise:

Coordinates (x,y) become (-x,-y)

4- Rotation 270° counter clockwise:

Coordinates (x,y) become (y,-x) ...........> same as rotation 90° clockwise

Now, let's consider the given problem:

1- Coordinates of D' if polygon ABCD rotates 90° counter clockwise to create A'B'C'D'

Original coordinates of point D are (2,2)

Rotation 90° counter clockwise means that the new coordinates will be (-y,x) which is (-2,2)

2- Coordinates of C'' if polygon ABCD rotates 90° clockwise to create A''B''C''D''

Original coordinates of point C are (1,3)

Rotation 90° clockwise means that the new coordinates will be (y,x) which is (3,-1)

3- Coordinates of A''' if polygon ABCD rotates 180° clockwise to create A'''B'''C'''D'''

Original coordinates of point A are (-4,2)

Rotation 180° clockwise means that the new coordinates will be (-x,-y) which is (4,-2)

4- Coordinates of B'' if polygon ABCD rotates 270° counter clockwise to create A''B''C''D''

Original coordinates of point B are (-2,4)

Rotation 270° counter clockwise means that the new coordinates will be (y,-x) which is (4,2)

<ACD = 35 degrees

Step-by-step explanation:

An intercepted angle is an arc segment of a circle whose endpoints connect at a point on the opposite side of the circle to create an angle. In this case arc AD is the intercepted arc of <ACD.

The measure of angle is half the measure of its intercepted arc.

AD measures 70 degrees, so divide this by 2.

70/2 = 35

<ACD = 35 degrees

Answer:

3.1 ft

Step-by-step explanation:

The segment from the centre of the circle to the chord is a perpendicular bisector.

Thus the third side of the right triangle is half of x

let the third side be a then x = 2a

Applying Pythagoras' identity to the right triangle with hypotenuse 2.1 then

a² + 1.4² = 2.1²

a² + 1.96 = 4.41 ( subtract 1.96 from both sides )

a² = 2.45 ( take the square root of both sides )

a = [tex]\sqrt{2.45}[/tex]

Hence x = 2 × [tex]\sqrt{2.45}[/tex] ≈ 3.1 ft

Answer:

Eva has 24 pins

Step-by-step explanation:

D = 34 + E

E + D = 82

34 + E + E = 82

2E = 48

E = 24

D = 24 + 34

D = 58

Sure! Let's solve it step by step.

1. We know from the problem that Dulcina has 34 more pins than Eva does. This means that Dulcina's collection is Eva's collection plus 34 pins.

2. Together, Eva and Dulcina have a total of 82 pins. This means that if we add the number of pins in both collections, it should total 82.

3. If we represent the number of pins in Eva's collection as 'x', the above two steps could be represented in equation as: x + (x + 34) = 82.

4. Simplifying this equation gives us 2x + 34 = 82. To isolate the term with 'x', we subtract 34 from both sides of the equation, resulting in 2x = 48.

5. To find the value for 'x', which represents the number of pins in Eva's collection, we then divide both sides of the equation by 2, which gives us x = 24.

6. So, Eva has 24 pins in her collection.

7. Now, since Dulcina has 34 more pins than Eva, we add 34 to Eva's total to find the number of pins in Dulcina's collection. This gives us Dulcina's total as 24 + 34 = 58.

Therefore, Eva has 24 pins and Dulcina has 58 pins in their collections.

Answer:

x = 60°

Step-by-step explanation:

The measure of x is one- half the difference of the measures of the intercepted arcs.

The minor arc = 120°, hence

The major arc = 360° - 120° - 240°, so

x = 0.5(240 - 120) = 0.5 × 120° = 60°

Answer:

Both ladder reaches 18.1 m up the building ⇒ 3rd answer

Step-by-step explanation:

* Lets study the information to solve the problem

- There are two ladders

- The lengths of them are 22 m and 20 m

- The bottom of the longer was 4 m farther than the bottom of the

  shorter from the building

- Both of them reached the same distance up the building

* Lets solve the problem

- Let the distance between the bottom of the shorter ladder to the

 building is x

∵ The bottom of the longer ladder is farther by 4

∴ The distance between the bottom of the longer ladder and the

   building is x + 4

- Let the ladders reached the distance h up the building

* Now we have two right triangles

# Their hypotenuses are 22 and 20

# Their heights are h

# Their bases are x + 4 , x

- Lets find h in each triangle using the rule of Pythagoras

∵ (hypotenuse)² = (leg 1)² + (leg 2)²

# The longer ladder

∵ hypotenuse = 22

∵ leg 1 = x + 4

∵ leg 2 = h

∴ (22)² = (x + 4)² + h² ⇒ simplify

∴ 484 = (x + 4)² + h² ⇒ subtract (x + 4)² from both sides

∴ h² = 484 - (x + 4)² ⇒ (1)

# The shorter ladder

∵ hypotenuse = 20

∵ leg 1 = x

∵ leg 2 = h

∴ (20)² = (x )² + h² ⇒ simplify

∴ 400 = x² + h² ⇒ subtract x² from both sides

∴ h² = 400 - x² ⇒ (2)

- Equate (1) , (2) to find x

∴ 484 - (x + 4)² = 400 - x² ⇒ Add (x + 4)² and subtract 400 in both sides

∴ 84 = (x + 4)² - x² ⇒ open the bracket

∴ 84 = x² + 2(4)(x) + 4² - x² ⇒ simplify

∴ 84 = 8x + 14 ⇒ subtract 16 from both sides

∴ 68 = 8x ⇒ divide both sides by 8

∴ x = 8.5

- Substitute this value of x in (1) or (2) to find h

∵ h² = 400 - x²

∴ h² = 400 - (8.5)² = 327.75 ⇒ take √ for both sides

∴ h = 18.1

* Both ladder reaches 18.1 m up the building

The measures of the angles of the triangle are 51° , 64.5° , 64.5°

OR

The measures of the angles of the triangle are 129° , 25.5° , 25.5°

Step-by-step explanation:

* Lets explain the meaning of the inscribed triangle in a circle

- If a triangle inscribed in a circle, then the vertices of the triangle lie

 on the circumference of the circle and each vertex is an inscribed

 angle in the circle subtended by the opposite arc

- Fact in the circle the measure of the inscribed angle is 1/2 the

 measure of its subtended arc

* Now lets solve the problem

- Δ ABC is an isosceles with the base BC

∴ AB = AC

∴ m∠B = m∠C

- Δ ABC is inscribed in a circle

∴ ∠A is inscribed angle subtended by arc BC (minor or major)

# The measure of the minor arc is less than 180° and the measure of

  the major arc is greater then 180° and the sum of the two arcs

  equals the measure of the circle which is 360°

∴ ∠B subtended by arc AC

∴ ∠C subtended by arc AB

∵ The measure of the arc BC = 102°

- There is two cases in this question

(1) If the angle A subtended by the minor arc BC

(2) If the angle A subtended by the major arc BC

- Lets solve case (1)

∵ ∠A is an inscribed angle subtended by the minor arc BC

∴ m∠A = 1/2 the measure of the arc BC

∵ The measure of the arc BC is 102°

∴ m∠A = 1/2 × 102 = 51°

∵ The sum of the measures of the interior angles of a triangle is 180°

∴ m∠A + m∠B + m∠C = 180°

∴ 51 + m∠B + m∠C = 180° ⇒ subtract 51 from both sides

∴ m∠B + m∠C = 129°

∵ m∠B = m∠C ⇒ isosceles Δ

∴ m∠B = m∠C = 129/2 = 64.5°

* The measures of the angles of the triangle are 51° , 64.5° , 64.5°

- Lets solve case (2)

∵ ∠A is an inscribed angle subtended by the major arc BC

∴ m∠A = 1/2 the measure of the arc BC

∵ The measure of the minor arc BC is 102°

∵ The measure of the circle is 360°

∴ The measure of the major arc = 360 - 102 = 258°

∴ m∠A = 1/2 × 258 = 129°

∵ The sum of the measures of the interior angles of a triangle is 180°

∴ m∠A + m∠B + m∠C = 180°

∴ 129 + m∠B + m∠C = 180° ⇒ subtract 129 from both sides

∴ m∠B + m∠C = 51°

∵ m∠B = m∠C ⇒ isosceles Δ

∴ m∠B = m∠C = 51/2 = 25.5°

* The measures of the angles of the triangle are 129° , 25.5° , 25.5°

$22.50

Step-by-step explanation:

The cost of admission for the 5 coaches was ...

5×$27.50 = $137.50

So the cost of admission for the 12 players was ...

$407.50 -137.50 = $270.00

The cost for one player was 1/12 that amount, or ...

$270/12 = $22.50

The admission cost for each player was $22.50.

The admission cost for each player is $22.50.

To find the admission cost for each player, we need to subtract the cost of admission for the coaches from the total cost of admission for all the coaches and players. The cost for five coaches is $((5  imes 27.50) = 137.50). So, the cost for the 12 players is $(407.50 - 137.50 = 270).

Therefore, the admission cost for each player is $22.50.

15 is 11/2% larger than 2.72

I am 99.9% sure that is the correct answer but I could be wrong.

To represent the word problem '15 is 1 1/2% of what number?' using a proportion, we can set up the form %1 1/2/100 = 15/n. By cross multiplying and solving for 'n', we find that 15 is 1 1/2% of 1000.

To represent the word problem '15 is 1 1/2% of what number?' using a proportion, we can use the form %0/100 = is/of. Let's assign 'n' to represent the unknown number. We can set up the proportion as follows:

%1 1/2/100 = 15/n

Now, we can solve for 'n' by cross multiplying and then dividing. First, convert 1 1/2% to a decimal by dividing 1 1/2 by 100 to get 0.015. The proportion becomes:

0.015 = 15/n

To solve for 'n', we can multiply both sides of the equation by 'n':

0.015n = 15

Finally, divide both sides of the equation by 0.015 to isolate 'n':

n = 15/0.015 = 1000

Therefore, 15 is 1 1/2% of 1000.

Answer:

Step-by-step explanation:

Note that the distance, along a straight line, from A:  -2 to B:  7 is 9 units.

This is found by subtracting -2 from 7, so x2 = 7 and x1 = -2.

Then x = (x2 – x1) + x1 becomes x = (7 - [-2] ) + [-2], or x = 7.  This does not make sense.  

If we ignore this x = (x2 – x1) + x1, and focus instead on finding the division point in this line segment:

4 + 3 = 7, so the longer part of this 9-unit distance will be (4/7)(9), or 36/7 units long, or 5  1/7 units long.  The shorter part will be (3/7)(9), or 27/7 units long.
