Answer:

Step-by-step explanation:

Number of students 10

Problem 1. $625 for the bus hire per friday, So 625*4=$2500

Problem 2. 2500/25=$100 each for the whole 4 weeks

Problem 3.

10 students tickets 220= 2200 for all tickets. The bus, 625/10 = $62.5*4= $250 dollars for the whole 4 weeks for the bus so in all each student pays $470 each

20 students, tickets 220=4400 for all tickets. The bus, 625/20=$31.25*4=$125 for the whole 4 weeks for the bus, so in all each student must pay $345 each

30 students, tickets 220 = 6600 for all tickets. The bus, 625/30 =$20.83*4=$83.32 for the whole 4 weeks for the bus, so in all each student must pay $303.32 each

41 students, tickets $160=$6560 for all tickets. The bus, because you need 2 buses at 625 each so $1250 for both buses 1250/41= 30.49*4=$121.96 for the whole 4 weeks for the bus. So in al each student must pay $281.96 each

Hope this is correct

Answer:

x=7

Step-by-step explanation:

8x – 2y = 48

Let y = 4

8x - 2(4) = 48

8x - 8 = 48

Add 8 to each side

8x-8+8 = 48+8

8x = 56

Divide each side by 8

8x/8 = 56/8

x=7

Answer:

[tex]x = 7[/tex]

Step-by-step explanation:

[tex]8x - 2y = 48 \\ 8x = 48 + 2y \\ x = \frac{48 + 2y}{8} [/tex]

[tex]y = 4[/tex]

[tex]x = \frac{48 + 2y}{8} \\ x = \frac{48 + 2 \times 4}{8} \\ x = \frac{48 + 8}{8} \\ x = \frac{56}{8} \\ x = 7[/tex]

Answer:

14.9 grams

Step-by-step explanation:

8.3+6.6=14.9

Answer:

Step-by-step explanation:

The combinations are defined as

[tex]C^{r}_{n}=\frac{n!}{(n-r)!}[/tex]

Where [tex]n[/tex] is the total number of elements and [tex]r[/tex] is the number of letter we are gonna picke, which is two. Using this information, we have

[tex]C^{2}_{6}=\frac{6!}{(6-2)!}=\frac{6!}{4!}=\frac{6 \times 5 \times 4!}{4!}=30[/tex]

Therefore, there are 30 possible combinations of picking two letters.

Force, F = 51300 N

Step-by-step explanation:

We have,

Mass of a car is 1350 kg

Acceleration of the car is 38 m/s².

It is required to find the force required to accelerate the car. The force acting on the object is given by the formula as follows:

[tex]F=ma\\\\F=1350\ kg\times 38\ m/s^2\\\\F=51300\ N[/tex]

So, the force of 51300 N is required to accelerate the car.

Answer:

4, 5 and 27.

Step-by-step explanation:

There are 2 cube numbers between 0 and 36 .

They are 8 and 27.

36 - 27 = 9 so the other 2 numbers could be 4 and 5 because they are both factors of 20.

36 - 8 = 28  whose factors are 2 * 2 * 7 which are not factors of 20.

The probability of reference book and then, without replacing it, picks up a nonfiction book is 5/136.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

Given:

Nadia's bookshelf contains 10 fiction books, two reference books, and five nonfiction books.

So, the probability of getting reference book

= 2/ 17

and, the probability of getting nonfiction book

= 5/ 17

Now, the probability of reference book and then, without replacing it, picks up a nonfiction book

= 2/ 17 x 5 / 16

= 10 / 272

= 5 /136

Answer:

$66.80

Step-by-step explanation:

The monthly payment can be computed using the pmt formula in excel spreadsheet as shown below:

=pmt(rate,nper,-pv,fv)

the rate is the interest rate of 3.5% divided by 12 months to show interest rate per month

nper is the number of months it would take to complete the payments which is 4 years multiplied by 12 months i.e 48 months

pv is the cost of the gadget at $2,988

fv is the sum of all month payments which is not unknown

=pmt(3.5%/12,48,-2988,0)=$66.80

Answer:

y=2(x square)-2x-3

Step-by-step explanation:

Let dy with y varibles in a hand

And dx with x variables on the other hand

dy=(4x-2)dx

Then by integration

y=2(square x)-2x+constant

Then substitute by x=-1 and y=1 to find the value of the constant

1=2(1)-2(-1)+ constant

Then constant=-3

Then the equation is

y=2(x square)-2x-3

For this question you have to solve every inequality. To get the correct answer.

Answer:

108

Step-by-step explanation:

So the area of the rectangle is easy.

12 * 5 = 60

Now you have to do the triangles.

The height is (13 - 5) / 2 = 4

The bases are 12

The area of one is (12 * 4) / 2

The area of both is 12 * 4 = 48

60 + 48 = 108

Answer:

4 meters

Step-by-step explanation:

Given a quadratic equation in which the coefficient of [tex]x^2[/tex] is negative, the parabola opens up and has a maximum point. This maximum point occurs at the line of symmetry.

Since the divers height, y is modeled by the equation

[tex]y= -x^2 + 2x + 3[/tex]

Step 1: Determine the equation of symmetry

In the equation above, a=-1, b=2, c=3

Equation of symmetry, [tex]x=-\dfrac{b}{2a}[/tex]

[tex]x=-\dfrac{2}{2*-1}\\x=1[/tex]

Step 2: Find the value of y at the point of symmetry

That is, we substitute x obtained above into the y and solve.

[tex]y(1)= -1^2 + 2(1) + 3=-1+2+3=4m[/tex]

The maximum height of the diver is therefore 4 meters.

Step-by-step explanation:

Answer:

[tex]x = 8[/tex]

Step-by-step explanation:

According to PYTHAGORAS theorem

[tex] {6}^{2} + {x}^{2} = {10}^{2} \\ 36 + {x}^{2} = 100 \\ {x}^{2} = 100 - 36 \\ {x}^{2} = 64 \\ x = \sqrt{64} \\ x = 8[/tex]
