AREAS AND VOLUMES OF SIMILAR SOLIDS URGENT?
Llana [10]

Formula for the volume of cone is \frac{1}{3} \pi r^2h

Where r= radius of the cone

h = height of the cone

The value of pi is 3.14

Given volume of larger cone is 131 cm^3

Volume of larger cone = \frac{1}{3} \pi r^2h

131 = \frac{1}{3} \pi 5^2h

Solve for h

131 = 26.1667 *h

So h= 5 cm

The height of bigger cone = 5cm

Now we find the volume of smaller cone

Two cones similar so the sides are in proportional

\frac{radius(small)}{radius(large)}=  \frac{height(small)}{height(large)}

\frac{2}{5} =\frac{ height of small}{5}

Height of smaller cone = 2cm

volume of smaller cone = \frac{1}{3} \pi 2^2*2

= 8.38cm^3

After reading 80% of her e-mails in her inbox, Danette still has M unread e-mails. Which of the following expressions could repr
sergey [27]

Answer:

(Choice A) 5M

Step-by-step explanation:

Let total no. of e-mails in inbox be x

Since she read 80 % of mails i.e 80 % of x

⇒80\% \times x

⇒\frac{80}{100}\times x

⇒0.8 x

So, she read 0.8x e-mails.

So, remaining email = total e-mails - read e-mails

                                  =x-0.8x

Since we are given that Danette still has M unread e-mails.

⇒ M=x-0.8x

⇒ M=x(1-0.8)

⇒ M=x\times 0.2

⇒ \frac{M}{0.2}=x

⇒ \frac{10M}{2}=x

⇒ 5M=x

Thus the expression  represent the number of e-mails Danette had in her inbox before she started reading is 5M.

Hence Choice A is correct.
