The system of  equations can be used to find the cost of a  night's stay and the cost of a meal is:

2n + 5m = $395

5n + 11m = $959

Simultaneous equations are two or more groups of equations. These equations have to be solved together at the same time in order to determined the required valued. The two above equations have to be solved in order to determine the cost of  a  night's stay and the cost of a meal.

Answer:

£960

Step-by-step explanation:

First, we calculate VAT.

20% of £800 =

= 20/100 × £800

= 0.2 × £800

= £160

VAT is £160

Now we add VAT to the cost of the TV.

£800 + £160 = £960

Answer:

c = 41

Step-by-step explanation:

a^2 + b^2 = c^2

Pythagorean Theorem

Answer: 41.0 for the 1st question. 50.0 for the 2nd question.

Oki soooo, in the first sum we know that it is a right angle triangle from that square thingy on the corner of the triangle. The missing side that we are told to find is known as the hypotenuse. Whenever there is a right angle in a triangle with two side lengths given except the hypotenuse side; always remember to use the pythagorean theorem!

In mathematics, the Pythagorean theorem, or Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides. And it's formula is:

c^2 = a^2 + b^2

Where c is the hypotenuse side, a is one of the side length except the hypotenuse and b is the remaining side length except the hypotenuse and the length that you already use for a. Now let's place the value! >:)

c^2 = a^2 + b^2

c^2 = 9^2 + 40^2

c^2 = 81 + 1600

c = square root of 1681

c = 41

Since c was the hypotenuse and this is what the question wanted from you U_U! To 1 decimal place would be 41.0

~`*^! Now for the 2nd question, the question asks for hypotenuse again so place the values by yourself and try doing it yourself to see if your correct! Scroll down to see if what you did was correct or not! Only then you can make sure that you understood on how to do this! And make sure to remember the formula: c^2 = a^2 + b^2

c^2 = a^2 + b^2

c^2 = 30^2 + 40^2

c^2 = 900 + 1600

c = square root of 2500

c = 50

As decimal, 50.0

Answer:

A is the solution!

Step-by-step explanation:

-1.6

Answer:

the value of x in the above equation is 7.35

The angle of sine has a value of 3/5.

Option A is the correct representation of angle sin(b°).

Given that tan(b°) = 3/4 and cos(b°) = 4/5.

In trigonometry, we know that,

[tex]\dfrac {sin \theta}{cos \theta} = tan \theta[/tex]

The angle of sine can be written as below.

[tex]sin \theta = cos \theta \times tan \theta[/tex]

For the angle b, the above expression can be written as,

[tex]sin (b^\circ) = cos (b^\circ) \times tan (b^\circ)[/tex]

Substituting the values in the above expression, we get,

[tex]sin (b^\circ) = \dfrac {3}{4} \times \dfrac {4}{5}[/tex]

[tex]sin (b^\circ) = \dfrac {3}{5}[/tex]

Hence we can conclude that the angle of sine has a value of 3/5.

7. The first option x<- 4

8. The two sides of the equations are not equal.

Step-by-step explanation:

The correct option is "Segment DE, segment EF, and segment DF are all different lengths, and the slopes of segment DE and segment EF opposite reciprocals".

A scalene triangle is a triangle whose all three sides are of different lengths.

We know that to show that the two lines are perpendicular their slope must be reciprocal and opposite of each other.

ΔDEF is a right, scalene triangle

In a right-angled triangle, there must be an angle of 90°, therefore, the line segments should be perpendicular to each other. Thus, the slope of the two-line segments must be reciprocal of each other.

Also, we want that the triangle must be a scalene triangle, and for a triangle to be scalene all the sides of the triangle must be different in length.

Hence, the correct option is "Segment DE, segment EF, and segment DF are all different lengths, and the slopes of segment DE and segment EF opposite reciprocals".

Answer:

37 ft²

Step-by-step explanation:

We can decompore this shape into a square with side length 4 and a triangle with base 7 and height 6.

The area of the square is 4·4=16

The area of the triangle is 6·7/2=3·7=21

The area of the total shape is 16+21=37

Solution:

Then,

x ÷ 2 - 7 = 17

or, x/2 - 7 = 17

or, x/2 = 17 + 7

or, x/2 = 24

or, x/2 × 2 = 24 × 2

or, x = 48

So, the number will be 48.

Verification:

LHS

= 48 ÷ 2 - 7

= 24 - 7

= 17

= RHS

Answer:

24

Hope you could understand.

If you have any query, feel free to ask.

Step-by-step explanation:

I guess, our job is to find out the number to put into the blue dot, so that the squadron is true.

that is called solving the equation.

and the blue dot is a "variable". let's call it x.

so,

x/2 - 7 = 17

now, by making the same transformations on both sides of the "=" sign we don't change the meaning of the equation. we just make it clearer to understand.

so, for example, we can add 7 to both sides.

and we get

x/2 = 24

aha !

now only the fraction is a little bit disturbing.

so, let's multiply both sides by 2.

and we get

x = 48

and there is our answer.

if and only if we put "48" as number into the blue dot, the equation is true. for any other value it is false.

Answer:

what is a common denominator for 3 1/2 and 1 2/5

Step-by-step explanation:

1/2 and 3/5

Look for the lowest common multiple, LCM, of 2 and 5.  That is the

smallest number that 2 and 5 both divide into evenly with no remainder.

2, 4, 6, 8, 10

5, 10

The LCM is 10 so that will be the common denominator.

To turn 1/2 into x/10 we need to multiply the denominator, 2, by 5

so multiply 1/2 by 5/5:   (1/2)(5/5) = 1(5)/[2(5)] = 5/10

To turn 3/5 into x/10 we multiply the denominator, 5, by 2

so multiply 3/5 by 2/2:  (3/5)(2/2) = 3(2)/[5(2)] = 6/10

1/2 + 3/5 = 5/10 + 6/10 = (5+6)/10 = 11/10 or 1 1/10

Your pair of fractions is 5/10 and 6/10

Answer: 5870 rounded to the nearest thousand is 6000

Step-by-step explanation:

Remember, when we round we have to be careful with the place value they are asking you to round to. Here, they want you to round to the thousands place. So, you have to look at the hundreds.

5870. 800 is the hundreds, and it is greater than “5”. So, you round to the next thousands. It happens to be 6000.

Hence, 5870 rounded is 6000.

Answer:

[tex]h^{-1}[/tex] (x) = 5 - 3x

Step-by-step explanation:

let h(x) = y and rearrange making x the subject

y = - [tex]\frac{1}{3}[/tex] x - [tex]\frac{5}{3}[/tex] ( multiply through by 3 to clear the fractions )

3y = - x - 5 ( add 5 to both sides )

3y + 5 = - x ( multiply through by - 1 )

- 3y - 5 = x

change y back into terms of x with x = [tex]h^{-1}[/tex] (x) , that is

[tex]h^{-1}[/tex] (x) = - 3x - 5

Answer:

Step-by-step explanation:

I wrote an excel macro that listed all of the combinations of these 6 numbers in a string, with the x and = symbols mixed in every possible way. (The first combination was “1*2=4568” and the last one was “8654=2*1”) I then had the macro evaluate the equations and find the ones that evaluated to true. Out of the 18,000 combinations of numbers and math symbols, only 8 of them evaluated to true. The true combinations are…………..

416=52*8

416=8*52

512=64*8

512=8*64

52*8=416

64*8=512

8*52=416

8*64=512

(Note that there are only 2 distinct combinations that work. The macro found all the ways that you can express those 2.)
