Answer:

£1638.40

Step-by-step explanation:

Step one:

Given data

A car costs £5000 when new

Each year the value decreases by 20%.

Step two:

let us compute the worth in the next 5 years

year 1

worth= 5000- 0.2*5000

worth= 5000-1000

worth= £4000

year 2

worth= 4000- 0.2*4000

worth= 4000-800

worth= £3200

year 3

worth= 3200- 0.2*3200

worth= 3200-640

worth= £2560

year 4

worth= 2560- 0.2*2560

worth= 2560-512

worth= £2048

year 5

worth= 2048- 0.2*2048

worth= 2048-409.6

worth= £1638.40

The person is wrong because after 5 years the car is worth £1638.40

This table shows the relationship of the total number of pieces of fruit to the number of bananas.

ddd [48]

Given:

The table that shows the relationship of the total number of pieces of fruit to the number of bananas.

To find:

Why is $\dfrac{6}{5}$ not equivalent to $\dfrac{3}{2}$ .

Solution:

If a, b, c are real numbers, then

$\dfrac{a}{b}=\dfrac{a\times c}{b\times c}$

The given fraction is $\dfrac{3}{2}$ . It can be written as:

$\dfrac{3\times 2}{2\times 2}=\dfrac{6}{4}$

The number 3 is multiplied by 2 to get 6. So, the 2 should also be multiplied by 2. The ratio should be $\dfrac{6}{4}$ , not $\dfrac{6}{5}$ .

Therefore, the correct option is A.

A 3-meter roll of red ribbon costs $1.89. What is the unit price?

Elan Coil [88]

Answer:

The price of ribbon is $0.63 per meter.

Step-by-step explanation:

It is given that:

Cost of 3 meter ribbon = $1.89

Unit price per meter = $\frac{1.89}{3}$

Unit price per meter = $0.63 per meter

Therefore,

The price of ribbon is $0.63 per meter.

XYZ has coordinates X(2, 3), Y(1,4), and Z(8,9). A translation maps X to X'(4,7). What are the coordinates for Y' and Z' for thi

Rashid [163]

Answer:

The coordinates are $Y'(x,y) = (3, 8)$ and $Z'(x,y) = (10, 13)$ .

Step-by-step explanation:

First, we have to derive an expression for translation under the assumption that each point of XYZ experiments the same translation. Vectorially speaking, translation from X to X' is defined by:

$X'(x,y) = X(x,y) + T(x,y)$ (1)

Where $T(x,y)$ is the vector translation.

If we know that $X(x,y) = (2,3)$ and $X'(x,y) = (4,7)$ , then the vector translation is:

$T(x,y) = X'(x,y)-X(x,y)$

$T(x,y) = (4,7) - (2,3)$

$T(x,y) = (2, 4)$

Then, we determine the coordinates for Y' and Z':

$Y'(x,y) = Y(x,y) + T(x,y)$

$Y'(x,y) = (1,4) + (2,4)$

$Y'(x,y) = (3, 8)$

$Z'(x,y) = Z(x,y) + T(x,y)$

$Z'(x,y) =(8,9) + (2,4)$

$Z'(x,y) = (10, 13)$

The coordinates are $Y'(x,y) = (3, 8)$ and $Z'(x,y) = (10, 13)$ .

What is the product of (–0.9)(–2.4)?<br> –3.3<br> –2.16<br> 2.16<br> 3.3

saul85 [17]

The answer would be 2.16.

This is because the two negatives would cancel each other out when multiplying. This would basically make the question $0.9*2.4$ .
Now 3.3 is definitely not less than 2.4, so the answer would be 2.16
