Point A lies on the circle and has an x-coordinate of 1.


Which is the correct calculation of the y-coordinate of point A?

Answer:

£200

Step-by-step explanation:

Let the original price of the camera be x.

The 10% discounted price of the camera is £180. This means that 10% of x was deducted from x to give £180:

x - (10/100 * x) = 180

x - 0.1x = 180

0.9x = 180

x = 180 / 0.9 = £200

The pre-sale price was £200.

Answer:

3 strain would still alive after 48 hours

Step-by-step explanation:

Initial population of virus = 40000 grams

A certain virus is dying off at a rate of 18% per hour.

We are supposed to find  how much of the  strain would still be alive after 48 hours

Formula : [tex]N(t)=N_0(1-r)^t[/tex]

[tex]N_0[/tex]=Initial population

N(t)= Population after t hours

r = rate of decrease = 18% = 0.18

t = time = 48 hours

So,the  strain would still be alive after 48 hours=[tex]40000(1-0.18)^{48}=2.91 \sim 3[/tex]

Hence 3 strain would still alive after 48 hours

Answer:

Multiplication

Step-by-step explanation:

Remember PEMDAS.

This is the order of operations

Parentheses, exponents, multiplication, division, addition, and subtraction.

That is the order you need to do things in, and in this case, since there are no other operations, the answer is multiplication.

Answer:

Given

Step-by-step explanation:

(-4/15)-(9/10)

LCM = 150

(-4/15)= (-40/150)

(9/10)= (135/150)

So the equation becomes

= (-40/150)-(135/150)

= (-40-135)/150

= (-40+-135)/150

= -175/150

= -7/6 ( divide both by 25 to simplify)

The simplified value of  (-4/15) - (9/10)  is -7/6

The given question is (-4/15) - (9/10)

⇒first take L.C.M 15 and 10 which is 30.

⇒divide 30 by both the denominator  10 and 15 which is 3 and 2 respectively.

⇒multiply 3*-9 and 2*-4

⇒now solve using sign.

(-4/15) - (9/10)

⇒[tex]\frac{(-4*2)-(9*3}{30}[/tex]

   ⇒[tex]\frac{-35}{30}[/tex]

  ⇒ [tex]\frac{-7}{6}[/tex]

Answer:

is greater than

Step-by-step explanation:

The answer is C less than we got it wrong

Step-by-step explanation:

The answer is D. x = 32 and x = 0

============================================================

Explanation:

Think of x-16 as y. In other words, let y = x-16

We have (x-16)^2 = 256 become y^2 = 256.

Solve for y to get y = 16 or y = -16. You apply the square root to both sides. Don't forget about the plus/minus. This is because (-16)^2 = (-16)*(-16) = 256. We square the negative as well.

--------

If y = 16, then y = x-16 solves for x to get

y = x-16

16 = x-16

x-16 = 16

x = 16+16

x = 32 is one solution

---------

Plug in y = -16 and isolate x

y = x-16

x-16 = y

x-16 = -16

x = -16+16

x = 0 is the other solution

----------

We can check each answer by plugging them back into the original equation

Let's try x = 0

(x-16)^2 = 256

(0-16)^2 = 256

(-16)^2 = 256

256 = 256 ... works

Now try x = 32

(x-16)^2 = 256

(32-16)^2 = 256

(16)^2 = 256

256 = 256 ... also works; both answers have been confirmed

Answer:

Anna spent $51 in all.

Step-by-step explanation:

36+15=51

Answer:

$51

Step-by-step explanation:

Anna bought two items: a backpack and a lunch box. If we want to find the total amount of money Anna spent, we have to add the price of the backpack and the price of the lunchbox.

price of backpack+price of lunchbox

The backpack cost $36 and the lunchbox cost $15

$36+$15

Add 36 and 14

$51

Anna spent $51 in total

area of slope:  5m x 8m = 40m^2

area of base: 8 X 3 = 24 m^2

area of back: 8m x 4m = 32m^2

sum = surface area = 108m^2

Answer:

The difference between the bonus is £2.6

Step-by-step explanation:

First, you have to calculate the amount that Tom get for his bonus. So you have to multiply 30% to £96 :

[tex] \frac{30}{100} \times 96 = 28.8[/tex]

Next, you have to subtract Tom's amount from Sally's amount because Sally has the higher amount of bonus than Tom :

[tex]31.4 - 28.8 = 2.6[/tex]

Answer:

-39,063

Step-by-step explanation:

In this geometric, sequence, you are multiplying by -5. So, we can continue the sequence by mulitplying 375(your last value) by -5 and so on, until we have 7 total terms.

Now we add the terms together:

-3+15+-75+375+-1875+9375+-46875

=-3+15-75+375-1875+9375-46875

=-39063

Answer:

Distance between 2 stations= 8.94 miles

Step-by-step explanation:

The coordinates of Symphony Station is given by:

Symphony Station: (x₁ , y₁) : (1,2)

The coordinates of Elm station is given by:

Elm Station: (x₂ ,y₂) : (-3,-6)

We know that the distance formula can be used to find distance between these 2 points. Distance formula is given as

d= √((x₂ - x₁)² + (y₂ - y₁) ²)

Substitute values

d= √((-3 - 1)² + (-6 - 2) ²)

d= √((-4)²+(-8)²)

d= √(16+64)

d=√80

d= 8.94 miles

Answer:

(n - 1)/2

Step-by-step explanation:

F = (1 - 1/n) + (1 - 2/n) + (1 - 3/n) + ...(1 - n/n)

  = (1 + 1 ... + 1) - (1/n + 2/n + 3/n + ...n/n)

     (there are n terms of 1)

  = n - (1 + 2 + 3 + ... + n)/n

  = n - [n x (n + 1)/2]/n

  = n - [n x (n + 1)]/[2 x n]

  = n - (n+1)/2

  = (2n - n - 1)/2

  = (n - 1)/2
