Answer:

Step-by-step explanation:

SP = ₹ 2250

Loss = 1/2% = 0.5%

CP = \frac{100}{100-loss}*SP\\\\=\frac{100}{99.5}*2250\\\\

= ₹ 2261.31

b) Profit = 15%

SP = \frac{100+profit}{100}*CP\\\\= \frac{115}{100}*2261.31

= ₹ 2600.51

Evaluate each of the expressions in the list for y = 5. Drag and drop the correct number into each box to
malfutka [58]

Answer:

Step-by-step explanation:

To get the value of the expressions in list A and list B we will substitute y = 5 in each expression.                      

            List A                                        List B

1). 6 + 6y = 6 + 6(5) = 36              6y - 6 = 6(5) - 6 = 24

2). 6(y - 1) = 6(5 - 1) = 24               6(y + 1) = 6(5 + 1) = 36

3). 6y + 1 = 6(5) + 1 = 31                 1 + 6y = 1 + 6(5) = 31

Therefore, (6 + 6y) is equivalent to 6(y + 1)

6(y - 1) is equivalent to (6y - 6)

(6y + 1) is equivalent to (1 + 6y)

O. Find the distance between P (10,-7) and Q (7,- 10). Leave your answer in radical<br> form.
mr Goodwill [35]

Answer:

\sqrt{18} or 3\sqrt{2} units.

Step-by-step explanation:

To find the <em>distance between two points</em>, we can use the Distance Formula.

Distance Formula: d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

<u />

<u>Given:</u>

P (10, -7) ⇒ x₁ = 10, y₁ = -7

Q (7, -10) ⇒ x₂ = 7, y₂ = -10

Substitute the given values into the formula and simplify.

\\\implies d=\sqrt{\bold{(7-10)}^2+\bold{(-10-(-7))}^2}\\\\\implies d=\sqrt{\bold{(-3)}^2+\bold{(-10+7)}^2}\\\\\implies d=\sqrt{9+\bold{(-3)}^2}\\\\\implies d=\sqrt{\bold{9+9}}\\\\\implies d=\sqrt{\bold{18}}\\\\\implies d=\sqrt{\bold{9}\times2}\\\\\implies d=3\sqrt{2}

The distance between points P and Q is \sqrt{18} or 3\sqrt{2} units.

Free_Kalibri [48]
n\% \:\:off = (100 -n)\% \:\: of \:the\: original \:price
FinalPrice =
(Original Price \times(\frac{100\% - Discount}{100\%}))\times(\frac{100\% - Discount_2}{100\%}) =
\big(\$28.62\times(\frac{100\% - 25\%}{100\%})\big) \times(\frac{100\% - 15\%}{100\%}) =
\big(\$28.62\times(\frac{3}{4})\big) \times(\frac{17}{20}) \approx \$18.25

Matt will pay \$18.25 for the mixer
