The price of a toy usually costing £50 is increased to £65
Work out the percentage increase.

Answer:

I mightc be able to help you out.

The general equation for a circle is:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

Where the center is (h,k) and the radius is r.

The equation we are given is:

[tex](x-2)^2+(y+3)^2=80[/tex]

From this, the center is (2,-3), and the radius is [tex]\sqrt{80}[/tex], or [tex]4\sqrt{5}[/tex].

Let me know if you have any questions, thanks!

Answer:

  4) -438.75

  8) 539.68

  12) 22.54

Step-by-step explanation:

Put the values in place of the corresponding variables and do the arithmetic.

__

4) 6xy = 6(-7 1/2)(9 3/4) = -6(7.5)(9.75) = -438.75

__

8) I = prt = $2442 × 0.085 × 2.6 = $539.68

__

12) I = prt = ($578)(0.0325)(1.2) = $22.54

Answer:

1 1/2 gallons

Step-by-step explanation:

1/4 * 6 = 6/4 = 3/2

1/6+1/6+1/6+1/6+1/6+1/6 = 1 whole wall

that means it takes 6 times 1/4 gallon to finish the wall

Answer:

x = 12

Step-by-step explanation:

The sum of exterior angles is = 360

one of the angle is given we will need to add all three angles

128 + 8x + 11x + 4 = 360 add like terms

19x + 132 = 360 subtract 132 from both sides

19x = 268 divide both sides by 19

x = 12 replace x in required expressions to find the measure of the angles

The value of x when y = 84 is 14

From the question,

The value of y varies directly with x

That is,

y ∝ x

Introducing the constant of proportionality, k

We get,

y = kx

Also, from the question

If x = 3, then y = 18

Putting these values into the equation, we can determine the value of k

[tex]y = kx[/tex]

[tex]18 = k \times 3[/tex]

Now, divide both sides by 3

[tex]\frac{18}{3}=\frac{k \times 3}{3}[/tex]

[tex]6 = k[/tex]

∴ k = 6

Now, to determine the value of x when y = 84

We will put y = 84 and the value of k =6 into the equation

[tex]y = kx[/tex]

[tex]84 = 6 x[/tex]

Divide both sides by 6

[tex]\frac{84}{6} = \frac{6x}{6}[/tex]

[tex]14 = x[/tex]

∴ [tex]x = 14[/tex]

Hence, the value of x when y = 84 is 14

Answer:

50%

Step-by-step explanation:

The percent gain is calculated as

[tex]\frac{gain}{original}[/tex] × 100%

gain = 27 - 18 = 9 , then

percent gain = [tex]\frac{9}{18}[/tex] × 100% = [tex]\frac{1}{2}[/tex] × 100% = 50%

Answer:

The probability to roll a number greater than 3 is 3 over the 6 total (1,2,3,4,5,6).

That can be simplified to 1/2 for the probability.

If she rolls the dice 90 times 90 x 1/2 or 45 rolls will receive a number greater than 3.

A2 =A1*2

this A2 cell we just fill down at least to the 10th line to A10.

A10 then will display the 10th number of the list.

overall, we can see that the 10th number must be

3×2⁹

as the first number is just a constant (the starting value), and each of all the other 9 numbers are multiplying by 2.
