If n^3=x and n^4=20x , where n>0, what is the value of x?

Natali5045456 [20]

Step-by-step explanation:

∠2 and ∠7 are alternate exterior angles so they are equal.

So you can create the equation

40x-48 = 20x+52 Subtract 20x from both sides. Add 48 to both sides.

20x = 100

x = 5

if you need m∠2 Substtute 5 for x in 20x+52

20(5) + 52 = 100 +52 m∠2= 152°

m∠7 40(5) - 48 = 200-48 m∠7= 152°

FIND THE VOLUME OF A CONE 0F DIAMETER 14M AND HEIGHT 21CM. (TAKE = 3 )

Ksenya-84 [330]

Answer:

343π

Step-by-step explanation:

To find the volume of a cone, we have to use this formula

$\frac{1}{3}$ × π × r² × h

Where 'r' is the radius and 'h' is the height

Let's start putting in the value's

We have diameter but in the formula we need the radius so we half the diameter to get the radius so 14 ÷ 2 = 7

$\frac{1}{3}$ × π × r² × h

$\frac{1}{3}$ × π × 7² × 21

→ Simplify the expression

$\frac{1}{3}$ × π × 49 × 21

→ Simplify it further

Simplify the ratio 15:13

tino4ka555 [31]

15:13 is in its simplest form already, since 13 is a prime number and 15 is not a multiple of 13.
