Answer:

See below

Step-by-step explanation:

20% loss a year with initial value of £6000 can be shown as function:

V(t) = 6000*0.8^t

V(t) - is the value after t years

a) t = 1 year

V(1) = 6000*0.8 = £4800

b) t = 3 years

V(3) = 6000*0.8^3 = £3072

c) t = 8 years

V(8) = 6000*0.8^8 = £1006.63

Ray Of Light [21]

Answer:

The equation representing the number of purses Ceirra has is $c=3+\frac{1}{2}\times a$ .

Ceirra has 9 purses in her collection.

Step-by-step explanation:

Given,

Cierra has three more than 1/2 as many purses as Asia.

Solution,

Let the number of purses Cierra has be 'c'.

And also the number of purses Asia has be 'a'.

Now according to question, Cierra has 3 more than 1/2 purses as Asia has.

Framing in equation form, we get;

$c=3+\frac{1}{2}\times a$

Hence The equation representing the number of purses Ceirra has is $c=3+\frac{1}{2}\times a$ .

Now we solve the equation;

Since Asia has 12 purses.

So we substitute the value of 'a', and get;

$c=3+\frac{1}{2}\times12=3+6=9$

Hence Ceirra has 9 purses in her collection.

The shape in the figure is constructed from several identical squares. If the side of each square is 1 unit, what is the area an

alexdok [17]

Answer:

Area: 7 units²

Perimeter: 14 units

Step-by-step explanation:

Area of each square:

1 unit × 1 unit = 1 unit²

There are 7 squares:

1 unit² × 7 (squares) = 7 units²

The area of the shape is 7 units².

The perimeter of the shape is the length of the outer sides.

1 + 1 + 1 + 1/2 + 1/2 + 1 + 1 + 1/2 + 1 + 1/2 + 1 + 1 + 1 + 1 + 1 + 1 = 14 units

1/5 =. 3/ 15 because you are multiplying the numerator by 3 so the denominator has to be multiplied by 3 as well

7/8 =. 14/16 because you are multiplying the numerator by 2 the denominator has to be multiplied by 2 as well

1/6. =. 2/12 because you are multiplying the numerator by 2
