Seven friends go out for dinner and the bill for food and drink comes to £140 the friends decide to add a 5% tip on top of this total if they divide the expense equally between them how much does each friend pay

Answer:

$140.74

Step-by-step explanation:

Assuming this is a decaying exponential function, we can find a model for the depreciation in the form of v = a(b^t)

At t = 0, we get 5000 = a(b^0), which gives us a = 5000

At t = 1, we get 4000 = 5000b, such that b = 4/5

Now that our function is defined as v = 5000(4/5)^t, we can plug in t = 16 to solve for the value of the piano.

v = 5000(4/5)^16, which is approximately $140.74.

Answer:

70

Step-by-step explanation:

70 x 0.10 = 7

Answer:

10% of 70 is equivalent to 7.

Step-by-step explanation:

If 10% of something is 7, then 7 divided by 10% is equivalent to that number. [tex]7[/tex] / [tex]\frac{10}{100}[/tex] = [tex]7 * 10[/tex] = 70.

Answer:

A = 27.2 mm²

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

Here b = 8 and h = 6.8 , then

A = 0.5 × 8 × 6.8 = 4 × 6.8 = 27.2 mm²

Answer:

Step-by-step explanation:

Let x represent the quantity of 12% solution in the mix. The the total amount of acid is ...

  12%x +4%(12 -x) = 9%(12)

  8x = 60 . . . . . . . . . . divide by %, subtract 48

  x = 60/8 = 7.5 . . . . . ounces of 12% solution

  12 -x = 4.5 . . . . . . . . ounces of 4% solution

Answer:

8.058655822 mins

Step-by-step explanation:

We have a  table and to solve for this we might want to find the  equation for this

This is a exponential function

To solve for this we need the rate of decay and the x intercept

We know the x intercept is 180 because in 0 mins the temp is 180

To solve for decay we need to know the temp of the cake after 1 min

to get the decay value we can do

125=  180 (x)^5

.69444444444 = x^5

0.929667185 = x

so the equation would be

180 (0.929667185)^x

if we tell this equation to equal 100

we get

100 = 180 (0.929667185)^x

.5556 = (0.929667185)^x

log .5556 = log 0.929667185 *x

log .5556 / log .929667185)

8.058655822= x

After 8.058655822 mins the cake will be 100 degrees

Answer:

QR, QT

Step-by-step explanation:

A radii is a line from the center of the circle to the circumfrence of the circle.

In this case the radii are QR, QT, and QK because they all start from the center of the circle which is point Q and stop at the circumfrence of the circle.

Since QK isn't an answer choice the only  answers are ...

QR and QT

Answer:

x=0, 1/2

Step-by-step explanation:

Answer:

x=0, x=1/2

Step-by-step explanation:

2x(x-1/2)=0​

Use the zero factor Principle

x=0 or x-1/2=0

Solve x-1/2=0;

Add 1/2 to both sides;

x-1/2+1/2=0+1/2

Simplify;

x=1/2

The solutions to the quadratic equations are;

x=0, x=1/2

Answer: 14 tomatoes were rotten

Step-by-step explanation:

Total number of tomatoes picked by Mrs Larkin= 70

Fraction of tomatoes rotten =4/20

Number of tomatoes rotten = fraction of tomatoes rotten x Total number of tomatoes picked

= 4/20 x 70

=1/5 x70

=14

With shapes like these, you need to split it into parts you can find the area for and add it together at the end.

Let's take the rectangle out of the two other triangles first,

15x8=120. First area solved.

Now remember, you find areas of triangles by bxh/2. Let's do the one on the side first. 9x8=72. 72/2=36. Second area solved.

The final triangle has a height of 7 m, and it's parallel to the 15 m length from before. 7x15=105, 105/2=52.5. Last area found.

Now let's add them all together. (120+36+52.5)=208.5.

Hope this helped!
