ali and beth divide £280 in the ratio 2:5 work out how much each person gets

Given:

Length of sheet of paper = 45 centimeters

width of the sheet of paper = 60 centimeters

To find:

The length of the diagonal cut that Eduardo made.

Solution:

We know that, a sheet of paper is a rectangle.

Diagonal of a rectangle is

[tex]Diagonal=\sqrt{length^2+width^2}[/tex]

Putting length = 45 and width = 60, we get

[tex]Diagonal=\sqrt{(45)^2+(60)^2}[/tex]

[tex]Diagonal=\sqrt{2025+3600}[/tex]

[tex]Diagonal=\sqrt{5625}[/tex]

[tex]Diagonal=75[/tex]

Therefore, the length of the diagonal cut that Eduardo made is 75 centimeters.

Answer:

$10750

Step-by-step explanation:

Given data

Total amount Skye needs= $17,150

We are told that each year She will receive $4300 in scholarships

and She will earn $2100 each year

Each year She will get= 4300+2100= $6400

Hence the deficit is = 17150-6400= $10750

Therefore the estimate cost she will have to pay per year is $10750

Answer:

10.63. I think this is correct

Answer:

√113

Step-by-step explanation:

Pythagorean Theorem : a^2 + b^2 = c^2

8^2 + 7^2 = c^2

64 + 49 = 113 = c^2

√113 = c

Answer:

The volume of the pyramid with a square base   V = 904.53 ft³

Step-by-step explanation:

Step(i):-

The length of the pyramid = 16 ft

The width of the pyramid = 16 ft

The height of the pyramid = 10.6ft

Step(ii):-

The volume of the pyramid with a square base

                 [tex]V = \frac{1}{3} a^{2} h[/tex]

                [tex]V = \frac{1}{3} (16)^{2} (10.6)[/tex]

               V = 904.53 ft³

Final answer:-

The volume of the pyramid with a square base

             V = 904.53 ft³

Answer:

904.5

Answer:

(f+g)x= 2x²+5x-3

The domain x∈ Real number.

Step-by-step explanation:

Given that f(x) = 5x - 3 and g(x) = 2x²

(f+g)x = f(x) + g(x)

So, by using the given function

(f+g)x= (5x-3) + (2x²)= 2x²+5x-3

As the result, 2x²+5x-3, is a polynomial, so domain of the result is all the real numbers.

Answer:

y=-2x-12

Step-by-step explanation:

first, putt 3x-6y=2 in standard form:

subtract 3x from both sides: -6y=-3x+2

divide both sides by -6 to isolate y: y=1/2x-1/3

if the other line is perpendicular to this, you must find the slope by finding the opposite reciprocal of 1/2x: -2

now we have 2 points a slope, so we use the point-slope formula: y-y1=m(x-x1)

y+2=-2(x+5)

Use the distributive property: y+2=-2x-10

subtract 2 for both sides to isolate y: y=-2x-12

2:x = 6

Step-by-step explanation:

Answer:

[1] x = -19

[2] x = 6

Explanation:

x - 7 + 7 = -26 + 7

x = -19

x + 5 = 11

x + 5 - 5 = 11 - 5

x = 6

Step-by-step explanation:

Answer:

(0 - 5) + 5

Step-by-step explanation:

Picture the initial floor you were on in the beginning as ground level or "zero." you go down five floors- so youre going below zero, which would be a negative. However, because you are going back up those five floors, you are back on ground level. Thus, the answer would be zero.

Answer:

43.2 years

Step-by-step explanation:

The formula for continuously compounded interest on a principal investment Pat a given interest rater

over time tin years is given by A = Pe^rt

P = Initial amount compounded = $12000

A = Amount compounded continuously after t years = six times it's original worth

= 6 × $12,000 = $72000

r = Interest rate = 4.15%

t = time in years = ?

Making t the subject of the formula

t = ln(A/P) / r

First, convert R percent to r a decimal

r = R/100

r = 4.15%/100

r = 0.0415 per year,

Then, solve our equation for t

t = ln(A/P) / r

t = ln(72,000.00/12,000.00) / 0.0415

t = 43.175 years

Approximately t = 43.2 years

The time required to get a total amount of $ 72,000.00 from compound interest on a principal of $ 12,000.00 at an interest rate of 4.15% per year and compounded continuously is 43.2years.

Hi! The correct answer is $7.5

Step-by-step explanation:

~to find the price of 1 seperate thing divide price by the amount that has been bought~

Answer:

The required numbers are: 36, 40, 44

Step-by-step explanation:

Let first number = 4x

Second number = 4(x+1)

Third number = 4(x+2)

There sum = 120

We need to find the numbers

We can write:

[tex]4x+4(x+1)+4(x+2)=120\\4x+4x+4+4x+8=120\\12x+12=120\\12x=120-12\\12x=108\\x=\frac{108}{12}\\x=9[/tex]

So, we get x = 9

Now, finding the numbers:

first number = 4x = 4(9) =36

Second number = 4(x+1) = 4(9+1) = 4(10) = 40

Third number = 4(x+2) = 4(9+2) = 4(11) = 44

So, The required numbers are: 36, 40, 44

Answer:

The answer is "[tex]R_0, 270^{\circ}\ and \ R_0, -90^{\circ}[/tex]"

Step-by-step explanation:

Please find the complete and correct question in the attached file.

The rule of rotating the origin is: [tex]270^{\circ} \ is\ (x,y) \to (y, -x)[/tex]

[tex]\therefore \\ \to (x, y) = (0,5)\\\\\to (y,-x)= (5,-0)= (5,0)\\\\R_0, 270^{\circ}\\[/tex]

So, the clockwise rotation is [tex]90^{\circ}[/tex] about origin changes [tex](x, y) \to (y, - x)[/tex]

[tex]\therefore\\\to (0, 5) \ changes \ are (5,0)\\\\R_0, -90^{\circ}[/tex]

Answer:

c and d

Step-by-step explanation:

Answer:

y = 5

x = -9

Step-by-step explanation:

5x + 13y = 20

-5x - 3y = 30

5x - 5x = 0

13y - 3y = 10y

20 + 30 = 50

10y = 50

y = 5

~~~~~~~~~~~~~~

5x + 13(5) = 20

-5x - 3(5) = 30

5x + 65 = 20

-5x - 15 = 30

5x = -45

-5x = 45

x = -9

Answer: increase

Step-by-step explanation: are there numbers to choose from....? The number would be greater than 45 because businesses wanna make more money .

EX-- if they bought it for 45 they could make it $50 to make a profit of $5.
