Solution set of 5/11x+1/3=3/7-6/11x+3/7

1 answer:

6 0

$\frac{5}{11x} + \frac{1}{3} = \frac{3}{7} - \frac{6}{11x} + \frac{3}{7} \\ \frac{11}{11x} = \frac{6}{7} - \frac{1}{3} \\ \frac{1}{x} = \frac{11}{21} \\ x = \frac{21}{11} = 1 \frac{10}{11}$

PLS HELP ITS MY FINAL EXAM What is the area of the base of the cone below? A cone with height 12 feet and volume 90 feet cubed.

hoa [83]

Answer:

$A=22.5\ \text{feet}^2$

Step-by-step explanation:

We have,

Height of a cone is 12 feet

Volume of the cone is 90 feet

It is required to find the area of the base of the cone.

The base of a cone is circular in shape.

The formula used to find the volume of a cone is given by :

$V=\dfrac{1}{3}\pi r^2 h$

here, $\pi r^2=A$ (area of base of cone)

$V=\dfrac{1}{3}\times Ah\\\\A=\dfrac{3V}{h}\\\\A=\dfrac{3\times 90}{12}\\\\A=22.5\ \text{feet}^2$

So, the area of the base of the cone is $22.5\ \text{feet}^2$ .

Step-by-step explanation:

triangle area formula- (B*H)/2

large triangle:

6+4+2=12

H=12

B=5

5*12=60

60/2=30

small trangle:

4*3=12
