David and Mark win some money and share it in the ratio 2:1. David gets £24 more than Mark. How much did they get altogether?

Answer:

less

Step-by-step explanation:

3/4 = 0.75

1/4 = 0.25

0.25*3 = 0.75

or

3/4 = 75%

1/4 = 25%

0.25*3 = 75%

Answer:

Less

Step-by-step explanation:

Fractions are proportions written using division. They are not whole numbers.

Proper Fractions

3/4 is less than 1 whole because it is a proper fraction. A proper fraction is a fraction that has a numerator that is smaller than the denominator. Remember that the numerator is the top number and the denominator is the bottom number. All proper fractions are less than 1. It is important to understand proper fractions in this question because improper fractions and mixed fractions are greater than 1.

This specific question asks about 3/4, which is 1/4 less than 1 whole.

Answer:

25

Step-by-step explanation:

The sum of all of the angles inside of a triangle is 180 degrees. That means we know that:

[tex](x+26)+(x+14)+(4x-10)=180[/tex]

We can then combine like terms:

[tex]6x+30=180[/tex]

We want to get 6x alone, so we can subtract 30 from both sides:

[tex]6x=150[/tex]

Then we want to get x alone, so we can divide both sides by 6:

[tex]x=25[/tex]

Now we know that x is 25.

x = 3

Answer:

Step-by-step explanation:

Given the expression  sin(11pi/2 +x) =-1/2

Take the arcsin of both sides

sin⁻¹[sin(11pi/2 +x)] =sin⁻¹(-1/2)

11pi/2 + x = -30

x = -pi/6 - 11pi/2

Find the LCM

x = (-pi-33pi)/6

x = -34pi/6

x = -17pi/3

Since x is negative and sin is negative in the fourth quadrant

x =  - 17pi/2

x = -1530⁰+1440⁰ (scaling down the angle)

x = -90

x = 360 - 90 (fourth quadrant)

x = 270⁰

x = 270pi/180

x = 27pi/18

x = 3pi/2

Hence x the solution of x is 3pi/2

Answer:

x = 76

Step-by-step explanation:

-4(x-26) = -4x + 104

-4x + 104 = -200

-4x = -304

x = 76

The solution of the equation is x= 76.

Two algebraic expressions having same value and symbol '=' in between are called as an equation.

Given, equation –4(x – 26) = –200

–4(x – 26) = –200

-4x + 104 = -200

-4x = -200-104

-4x = -304

x = 304/4

x= 76

Therefore, the solution of the equation is x= 76.

Answer:

The answer is 24.78 m^2

Step-by-step explanation:

I did the test

The outside circumference of the walking path is 50.24 meters and the inside circumference of the walking path is 25.12 meters then the area of the walking path is 150.72 m²

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

The formula for circumference of circle is 2πr

The area of circle is πr²

Area of large circle

Given:

circumference = 50.24 m

50.24 = 2 × 3.14 × r

r = 8 m

Therefore Area = 3.14 × 8²

= 200.96 m²

Area of small circle

Given circumference = 25.12 m

⇒ 25.12 = 2 × 3.14 × r

⇒ r = 4 m

Therefore Area = 3.14 × 4²

= 50.24 m²

Area of shaded path area = area of large circle - area of small circle

= 200.96 - 50.24

= 150.72 m²

Hence,  the area of the walking path is 150.72 m²

Check to be sure the answer makes sense.

Step-by-step explanation:

Answer:

If u have mixed fractions, like [tex]3\frac{1}{2}[/tex], you will have to change it to improper fraction([tex]\frac{7}{2}[/tex]) to divide with ease.

let's give an example of how to divide fractions.

1. [tex]\frac{2}{3}[/tex] ÷ [tex]\frac{1}{3}[/tex]

Now, you will invert the numbers on the right side, and that will cause the division sign to change into multiplication sign.

The percent of the bin would be filled for 30 gallons of amounts of waste is 60 percent.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Given that, a garbage bin can hold 50 gallons of waste.

Waste (gal) = 5

Percentage = 5/50 ×100

= 10%

Waste (gal) = 30

Percentage = 30/50 ×100

= 60%

Waste (gal) = 45

Percentage = 45/50 ×100

= 90%

Therefore, the percent of the bin would be filled for 30 gallons of amounts of waste is 60 percent.

Answer:

No it does not  matter in which order the store applies the discount.

Step-by-step explanation:

Suppose we have the cost price = $ 100

Then 70 %  off means 70% of 100= 70 $ discount

And the remaining $ 30  is again given a discount of 20 % . That would be 20 % of $ 30=  $ 6 discount giving the discounted price of $ 24.

Now if we apply the discount of 20 % first that would give $ 80 discounted price and again applying 70 % to $ 80 would give $ 56 discount and a discounted price of $ 80 - $ 56= $ 24

Hence the order in which the discount is applied does not matter.

Step-by-step explanation:

Answer:

a=3

Step-by-step explanation:

The formula for direct proportion is

f = ka

Let f= 42 and a = 7

42 = k*7

Divide each side by 7

42/7 = k7/7

6 =k

f = 6a

Let f = 18

18 = 6a

Divide each side by 6

18/6 = 6a/6

3 =a

Answer:

a = 3

Step-by-step explanation:

Given that F is directly proportional to a, then the equation relating them is

F = ka ← k is the constant of proportion

To find k use the condition F = 42 when a = 7, thus

42 = 7k ( divide both sides by 7 )

6 = k

F = 6a ← equation of proportion

When F = 18, then

18 = 6a ( divide both sides by 6 )

3 = a

x ≈ 57.8°

Step-by-step explanation:

using the Sine rule in the triangle

[tex]\frac{11}{sinx}[/tex] = [tex]\frac{8}{sin38}[/tex] ( cross- multiply )

8 × sinx = 11 × sin38° ( divide both sides by 8 )

sinx = [tex]\frac{11sin38}{8}[/tex] , then

x = [tex]sin^{-1}[/tex] ( [tex]\frac{11sin38}{8}[/tex] ) ≈ 57.8° ( to 1 dec. place )

Answer:

(fog)(x) = 2x² - 10x + 15

Step-by-step explanation:

Let us solve our question

∵ f(x) = 2x + 3

∵ g(x) = x² - 5x + 6

→ We need to compute (fog)(x)

∴ Substitute x in f(x) by g(x)

∵ (fog)(x) = 2(x² - 5x + 6) + 3

→ Multiply the bracket by 2

∵ 2(x² - 5x + 6) = 2(x²) - 2(5x) + 2(6)

∴ 2(x² - 5x + 6) = 2x² - 10x + 12

→ Substitute it in the composite function above

∴ (fog)(x) = 2x² - 10x + 12 + 3

→ Add the like terms 12 and 3

∴  (fog)(x) = 2x² - 10x + 15
