Explain two ways to find the sale price of an item marked 30% off

Answer:

multiply the original price by the decimal of 30% then x 100 Lets say the item was £10 original price = 0.30 / £10 = 0.3 x 100 =£3 Then £3 is the discount of £10=£7 The second way is easier for smaller numbers 10% of £10 = 1 and then 1 x 3 =3 =£3 discount = £7 new price.

Find 30% of the item and then subtract from the original value.

Find 70% of the item and that is your answer.

When using the given diagram to determine the area of the pentagon by decomposition, which statements are correct?:

pogonyaev

Answer:

Options (B) and (E)

Step-by-step explanation:

Area of ΔABC = $\frac{1}{2}(\text{Base})(\text{Height})$

= $\frac{1}{2}(14)(6)$

= 42 in²

Area of trapezoid ADEC = $\frac{1}{2}(b_1+b_2)h$

[Here, $b_1$ and $b_2$ are the parallel sides and 'h' is the height of the isosceles trapezoid given]

= $\frac{1}{2}(10+14)(8)$

= 96 in²

Area of the pentagon = Area of triangle ABC + Area of trapezoid ADEC

= 42 + 96

= 138 in²

Therefore, Options (B) and (E) are the correct options.

What is the slope of (-18,-20),(-18, -15)

Rzqust [24]

Answer:

Undefined.

Step-by-step explanation:

$m = \frac{rise}{run}$

$m = \frac{ - 15 - ( - 20)}{ - 18 - ( - 18)} \\ m = \frac{ - 15 + 20}{ - 18 + 18} \\ m = \frac{5}{0}$

The denominator is 0. Therefore, the slope is undefined.
