Answer:

$18 is the cost per ticket ordered

Step-by-step explanation:

We proceed as follows;

Let the cost per ticket be $x while the fixed fee be $y

For the person that ordered 5 tickets, we can have his mathematical representation as;

5(x) + y = 93 •••••••••(i)

For the person that ordered 3 tickets, we can have his mathematical representation as;

3(x) + y = 57 ••••••••(ii)

From the first equation, we can have;

y = 93 - 5x

Let’s plug this into ii

3x + 93 - 5x = 57

-2x = 57 -93

2x = 36

x = 36/2

x = $18

This means that the cost per ticket ordered is $18

Answer:

y=2x+15

Step-by-step explanation:

h=9

The equation to find the number of hours the boat was rented is $33 = $15 + ($2  imes h). After subtracting the deposit fee and dividing by the cost per hour, the solution is h = 9, indicating the boat was rented for 9 hours.

The equation to find out how many hours, h, the boat was rented for when the total cost was $33 can be represented as follows:

Total cost = Deposit fee + (Cost per hour  imes Number of hours)

Substituting the given values, we have:

$33 = $15 + ($2  imes h)

To solve for h, we subtract $15 from both sides of the equation:

$33 - $15 = $15 - $15 + ($2  imes h)

So, $18 = $2  imes h

Next, we divide both sides of the equation by $2 to solve for h:

$18 \/ $2 = ($2  imes h) \/ $2

h = 9

This means they rented the boat for 9 hours.

The soldiers used 562 cartridges in combat, while the subofficers used 138, using the total amount of ammunition and the difference between cartridges used.

The total amount of ammunition for the section is 175 per soldier for a total of 20 soldiers, so we have 175 * 20 = 3500 cartridges. A fifth of this ammunition is used in combat, that is, 3500/5 = 700 cartridges. According to the question, the number of cartridges used by the soldiers exceeds that of the subordinates by 424 cartridges, so we can establish a system of equations:

We can then solve this system and find that the soldiers used 562 cartridges and the subofficers used 138.

Answer:

NOTE: THIS IS AN EXAMPLE

Step-by-step explanation:

Let the Yellow Marbles be “X” and Red Marbles be “Y”

Total is 65, so X+Y = 65

Since we know that Yellow Marbles are 5 more than 4 times red marbles, let us convert that in terms of X and Y as well.

i.e, X = 4Y+5

Now replace X with (4Y+5) in the first equation we wrote above.

(4Y+5)+Y = 65

i.e, 5Y+5 = 65

5Y = (65–5),

5Y = 60

Therefore Y = 60/5 = 12

we know total is 65

So X= 65-Y

X=65–12 = 53

Therefore, the number of Yellow Marbles are 53 and the Red ones are 12.

Answer:

It is a combination answer

495 ways

Step-by-step explanation:

In this question, we are tasked with calculating the number of ways in which a manager can select 4 people out of 12 for the Sunday evening shift.

Firstly, the question talks about selecting a particular number from a mix, this is a combination question since the key word SELECT is mentioned.

Now, how do we go about it? To select a partial number from a mix , we use the combination formula as stated.

Mathematically, say we are selecting a number r from a total of numbers n, the number of ways we can do this is nCr = n!/(n-r)!r!

In this case however, we are simply selecting 4 out of 12

Our combinational equation thus becomes 12C4 = 12!/(12-4)!4! = 12!/8!4! = 495 ways

Final answer:

The manager can choose 4 from 12 employees in 495 different ways for the Sunday evening shift, using a combination rather than a permutation since the order of selection does not matter.

Explanation:

To determine the number of ways the manager can choose 4 out of 12 employees for the Sunday evening shift, we need to decide whether the order in which the employees are chosen matters. If the order does not matter, we will use a combination. If the order does matter, we would use a permutation. In this case, because the task is simply to choose 4 employees and the order in which they are chosen does not affect the outcome, we use a combination.

The formula for finding the number of combinations when choosing k objects out of a total of n objects without repetition is given by:

C(n, k) = n! / (k! * (n-k)!)

In this situation, we have n=12 and k=4, so we calculate:

C(12, 4) = 12! / (4! * (12-4)!) = 12! / (4! * 8!) = (12*11*10*9) / (4*3*2*1) = 495

Therefore, there are 495 different ways for the manager to choose 4 employees for the Sunday evening shift.

Answer:

Step-by-step explanation:

However, I personally think this does not make sense. A leaf blower should take more gas than oil, right? For this reason, I will provide an additional answer.

If the ratio of gas to oil is 40:1, then you would multiply by 4 to get 4 oz oil and 160 oz gas.

Alternate answer:

If the ratio of oil to gas is 40:1, then you divide by 10 on both sides to get 4 oz oil and .1 oz gas.

The net will have 1 square face

The net will have 4 triangular faces

The triangular faces are identical

The net will have a total of 5 faces.

Step-by-step explanation:

If you look at the picture, count the triangular faces, you will see 4.

Count the square on the bottom, its 1.

All the triangular faces are identical, if they weren't the picture would be all over the place.

Add 1+4 and it equals 5. The net will have a total of 5 faces.

(Hope you got it right, cause I took it and got it right!! Also I'm not good at explaining math lol)

Stay safe and social distance :DD

The net will have one square face, four triangular faces, the triangular faces are identical.

The net will have a total of five faces.

"It is a three-dimensional geometric shape that has a square base and four triangular sides that are joined at a vertex."

"It is a two-dimensional structure which forms a three-dimensional geometric structure by folding."

According to the problem,

The base of the square pyramid has a square and if a three dimensional structure of a net formed into a pyramid is looked at, we can see 1 face of the square at the base.

A pyramid is comprised of 4 triangles joined together at the vertex.

Again, if a three dimensional structure of a pyramid is looked at, we can see 4 faces of the pyramid.

Now in order to align into a single unit to be joined at the vertex, the triangles have to be identical. They will have similar faces with the same base and slant height.

Therefore, 1 square face and 4 triangular faces adds up to five total faces.

Hence, we can conclude that the net will have one square face, four triangular faces and a total of five faces with the triangular faces being similar.

Answer:

490mph and 510mph

Step-by-step explanation:

Let x mph and x+20 mph be the speeds of the planes. The rate at which their distance from each other increases will be the sum of their speeds which is 2x+20 mph.

Their distance from each other after three hours is ( 1.5 hours)*(2x+20 mph) = 3x+30 miles. We are given that this is 1500 miles so we can solve for x.

3x+30 = 1500

3x = 1500 - 30

3x = 1470

x = 1470/3

x = 490mph

For the second jet :

x +20 = 490+20

x = 510

Thus the speeds of the two planes are 490 mph and 510mph.

Answer: 1: 3x

2: area

3: six

4: 3/2

Step-by-step explanation:

The height of the pyramid can be represented as 3x, The area of the hexagon base is six times the area of the equilateral triangle, and the volume is 3/2 times √3 x³.

The pyramid has a hexagonal base with six isosceles triangular faces known as a hexagonal base pyramid. It is also called a heptahedron.

We have,

The length of the base edge of a pyramid = x units

The height of the pyramid is three times longer than the base edge ie.

The height of the pyramid = 3x

The area of an equilateral triangle with base length x units is [tex]\rm x\sqrt{3}[/tex] square units square(let's assume)

Then the area of the hexagon base = 6×[tex]\rm x\sqrt{3}[/tex] ⇒  6[tex]\rm x\sqrt{3}[/tex] square units.

Because the hexagon base has a six-equilateral triangle.

Let's assume the area of a hexagonal base is Y times the equilateral triangle.

[tex]\rm 6x\sqrt{3} = Y \times x\sqrt{3}[/tex]

Y = 6 times

We know the volume of a hexagonal pyramid = [tex]\frac{\sqrt{3} }{2} a^2h[/tex]

Where a is the base length and h is the height of the hexagonal pyramid.

Here a = x units and h = 3x units

Then Volume:

[tex]\frac{\sqrt{3} }{2} x^2(3x)\\\\\frac{{3} }{2} \sqrt{3}x^2[/tex]

Thus, the height of the pyramid can be represented as 3x, The area of the hexagon base is six times the area of the equilateral triangle, and the volume is 3/2 times √3 x³.

Answer:

Frank, Vanessa, Lois have 34, 17, 64 disks respectively

Step-by-step explanation:

In this question, we are to calculate the number of disks each of the 3 has.

Let the number of disks owned by Frank be x

for vanessa, she has half of what frank has and that would be x/2

Lois has 4 less than 2 times what Frank has, that would be 2x - 4

adding the 3, we have a total of 115 disks

This means that;

x + x/2 + (2x-4) = 115

Multiply throughout by 2;

that gives;

2x + x + 4x - 8 = 230

7x -8 = 230

7x = 230+ 8

7x = 238

x = 238/7

x = 34 disks

Frank has 34

Vaness has 34/2 = 17

Lois have 2x - 4 = 2(34) - 4 = 68 - 4 = 64 disks

Answer:

So Frank has 34 CDs, Vanessa has 17 CD's and Lois has 64 CDs

Step-by-step explanation:

Let's call the amount of CDs that Frank has by 'F', that Vanessa has by 'V' and that Lois has by 'L'. Then, we can write the following equations:

F = 2*V

L = 2*F - 4

F + V + L = 115

If we use the values of F and L in the third equation, we have that:

2*V + V + 2*(2*V) - 4 = 115

7*V = 119

V = 17 CD's

Now we can find F:

F = 2*V = 34 CDs

And then we find L:

L = 2*F - 4 = 68 - 4 = 64 CDs

So Frank has 34 CDs, Vanessa has 17 CD's and Lois has 64 CDs

Given:

Triangle ABC is similar to triangle XYZ.

The measures of the sides are AB = 6 cm, BC = 18 cm and XY = 12 cm

We need to determine the measure of side YZ.

Measure of YZ:

Since, ABC and XYZ are similar triangles, by using similar triangles property, we have;

[tex]\frac{AB}{XY}=\frac{BC}{YZ}[/tex]

Let the length of YZ be x.

Substituting the values, we get;

[tex]\frac{6}{12}=\frac{18}{x}[/tex]

Cross multiplying, we get;

[tex]6x=12 \times 18[/tex]

[tex]6x=216[/tex]

Dividing both sides by 6, we have;

[tex]x=36[/tex]

Thus, the value of x is 36.

Hence, the measure of the side YZ is 36 cm.
