Rebecca had a piece of ribbon. She used 3/8 of it to tie a parcel. She used 1/5 of the remainder for a bookmark. Rebecca had 24

mestny [16]

Assume the length of the ribbon was X
after tieing the parcel , the reminder is X - 3/8 = 5/8 X
Rebecca used 1/5 of the reminder, so the remainder of the remainder is 4/5 of the remainder = (4/5) * (5/8X) = 24 cm
20/40X = 24
So X = 48 cm

Step-by-step explanation:

<u>Lateral Surface Area of a Cone</u>

Given a right circular cone of base radius r and height h, the lateral surface area is given by:

$A=\pi r\sqrt{r^2+h^2}$

We are given the lateral area of a funnel as A=236.64 square cm and the radius is r=4.75 cm. It's required to find the height of the cone. It can be calculated by solving for h.

Squaring:

$A^2=\pi^2 r^2(r^2+h^2)$

Dividing by $\pi r^2$

$\displaystyle \frac{A^2}{\pi^2 r^2}=r^2+h^2$

Subtracting $r^2$ :

$\displaystyle \frac{A^2}{\pi^2 r^2}-r^2=h^2$

Taking square root:

$\displaystyle h=\sqrt{ \frac{A^2}{\pi^2 r^2}-r^2}$

Substituting the values:

$\displaystyle h=\sqrt{ 251.472-22.5625}$

$\displaystyle h=\sqrt{ 228.909}$

h = 15.13 cm

Jane purchased a concert ticket on a web site. The original price of the ticket was $55. She used a coupon code to receive a 20%

Licemer1 [7]

Answer:

28%

Step-by-step explanation:

-The price after the coupon discount is calculated as;

$P_{ad}=P_r(1-d)\\\\=55(1-0.2)\\\\=\$44$

We reduce the discounted price by the service fee to determine the effective purchase price:

$P_f=P_{ad}(1-f)\\\\=44(1-0.1)\\\\=\$\ 39.6$

#Compare this final price to the original price:

$\bigtriangleup=1-\frac{Final}{Original}\\\\=1-\frac{39.6}{55}\\\\=0.28 \ \ or \ 28\%$

Hence, the final price was 28% less than the original price.
