What is the value of v?

All sides of a triangle have to add up to 180, so

(2v) + (3v) + (3v - 4) = 180

Simplify

8v - 4 = 180
+ 4 = +4
(8v = 184)/8

v = 23

The radius of the fruit is 3 times the radius of the seed. It is known that the seed has a volume of 100 cubic centimeters. What
kolezko [41]
The edible fruit=fruit-seed

alright

vsphere=4/3pir^3

so if the volume is 100
of the seed
100=\frac{4}{3}\pi r^3
find r
times both sides by 3/4
75=\pi r^3
divide both sides by pi
\frac{75}{\pi}= r^3
cube root both sides
\sqrt[3]{\frac{75}{\pi}}= r
this is the seed radius
3 times of taht is the radius of the fruit
3\sqrt[3]{\frac{75}{\pi}}=radiusfruit

input into equation
use radius fruit for r
V=\frac{4}{3}\pi r^3
V=\frac{4}{3}\pi (3\sqrt[3]{\frac{75}{\pi}})^3
V=\frac{4}{3}\pi (27)(\frac{75}{\pi})
V=\frac{8100\pi}{3\pi}
V=2700 cm^3

so the edible part is 2700-100=2600 cm³

What is the value of x?
Andrei [34K]

Answer:

x=2

Step-by-step explanation:

We will use the secant-secant Formula:

(whole secant) x (external part) =         (whole secant) x (external part)

(1+x+4) * (x+4) = (11+x+1) * (x+1)

Combine like terms

(x+5) (x+4) = (x+12) (x+1)

FOIL

x^2 + 4x+5x + 20 = x^2 +  x+ 12x + 12

Combine like terms

x^2 + 9 x + 20 = x^2 + 13 x + 12

Bring everything to the left

x^2 + 9 x + 20- (x^2 + 13 x + 12) = x^2 + 13 x + 12-( x^2 + 13 x + 12)

x^2 + 9 x + 20- (x^2 + 13 x + 12) =0

Distribute the minus sign

x^2 + 9 x + 20- x^2 - 13 x - 12 =0

Combine like terms

-4x +8 = 0

Subtract 8 from each side

-4x+8-8=0-8

-4x=-8

Divide each side by -4

-4x/-4 = -8/-4

x=2
