Answer:

(-18, 2)

Step-by-step explanation:

To rotate a point by 90°:

R₉₀ (x, y) = (-y, x)

R₉₀ (1, 9) = (-9, 1)

To dilate by 2:

D₂ (x, y) = (2x, 2y)

D₂ (-9, 1) = (-18, 2)

Amerada Hess company wants to make an oil container tank. Engineers are shown a sample tank. which is 1 meter in height, and the

bagirrra123 [75]

Since the sample is 1/25 the size and the size of the sample is 1m then:

$1 = \frac{1}{25} x$

x is the height of our container. we need to move 1/25 to the other side so we multiply both sides of the equation by 25.

$25 \times 1 = \frac{1}{25} x \times 25$

On the right side of the equation, 1/25 cancels out with 25 since:

$\frac{1}{25} \times 25 = 1$

so we are left with the 25 x 1 on the left:

$25 = x$

so the container is 25m; C.

The original price was £348.

Adding 20% to to something is the same as multiplying by 1.2

Therefore, £290 * 1.2 = £348
