Please help me this is very important
Virty [35]

Answer:

a. 24.5 $

b. 10.5 $

c. 7/10

Step-by-step explanation:

Given the original price of the sweater is: $ 35.

a) If you pay only $ \frac{7}{10} $ of the price, then the actual amount paid is: $ \frac{7}{10} \times 35 = \frac{49}{2} $ = 24.5 $.

b) Total amount Saved = Actual price - Price you paid

$ \implies $ Total Amount Saved = $ 35 - \frac{49}{2} $

$ = \frac{21}{2} $ = 10.5 $.

c) Fraction of the original price saved = Total amount Spent/Actual Price

$ \implies $ Total amount Saved = $ \frac{49}{2(35)} $

$ = \frac{49}{70} $ = $ \frac{7}{10} $

Find the distance between each pair of points.<br> 3) (6, -2), (8, -3)<br> 4) (7,-8), (-8, 2)
castortr0y [4]

Answer:

3) \sqrt{5}

4)5\sqrt{13}

Step-by-step explanation:

distance between two points:

d = \sqrt{(x_{2}-x_{1})^{2}+ (y_{2}-y_{1})^{2}}

we have:

3) (6, -2), (8, -3)

x_{1} = 6

y_{1} =-2

x_{2} = 8

y_{2} =-3

so we have:

d =\sqrt{(8-6)^{2}+ (-3-(-2))^{2}}\\\\d =\sqrt{(2)^{2}+ (-1)^{2}}\\\\d = \sqrt{4+ 1}\\\\d=\sqrt{5}

4) (7,-8), (-8, 2)

x_{1} = 7

y_{1} =-8

x_{2} =-8

y_{2} =2

d =\sqrt{(-8-7)^{2}+ (2-(-8))^{2}}\\\\d =\sqrt{(-15)^{2}+ (10)^{2}}\\\\d = \sqrt{225+ 100}\\\\d=\sqrt{325}\\\\d=5\sqrt{13}
