posledela3 years ago
4 0

Step-by-step explanation:

Since they are consecutive terms in an AP,

(1 - x) + (2x + 1) = 2(x + 3).

=> x + 2 = 2x + 6

=> x = -4.

Therefore the terms are 5, -1 and -7.

=> Common difference = -6.

The question is............
irina1246 [14]
A(n,s)=(ns^2)/(4tan(180/n)), n=number of sides, s=side length

A(8,4.6)=(8*4.6^2)/(4tan22.5)

A(8,4.6)=42.32/tan22.5 m  (exact)

A(8, 4.6)≈102.17 m^2  (to nearest hundredth of a square meter)

15. The height and yolume of a cylinder are 4cm and 616cm respectively. Calculate the diameter of the base. (take t = 27 쪽 A. 7c
irakobra [83]

Step-by-step explanation:

Given that,

  • Height of cylinder = 4 cm
  • Volume of cylinder = 616 cm³

To find,

  • Diameter of the base = ?

Firstly we'll find the base radius of the cylinder.

\longmapsto\rm{V_{(Cylinder)} = \pi r^2h}\\

<u>Accordi</u><u>ng</u><u> </u><u>to</u><u> </u><u>the</u><u> </u><u>qu</u><u>estion</u><u>,</u>

\longmapsto\rm{616= \dfrac{22}{7} \times r^2 \times 4}\\

\longmapsto\rm{616 \times 7 = 22 \times r^2 \times 4}\\

\longmapsto\rm{4312 = 88 \times r^2 }\\

\longmapsto\rm{\cancel{\dfrac{4312}{88}} =  r^2 }\\

\longmapsto\rm{49 =  r^2 }\\

\longmapsto\rm{\sqrt{49} =  r }\\

\longmapsto\rm{7 \; cm =  r }\\

Now,

\longmapsto\rm{Diameter = 2r }\\

\longmapsto\rm{Diameter = 2(7 \; cm) }\\

\longmapsto\bf{Diameter = 14 \; cm}\\

The required answer is 14 cm.

Gennadij [26K]
The answer is:  [C]:  " 3.200 * 10⁷  h " .
_________________________________________________
Explanation:
________________________________
19.2 * 10⁸  min * (1 hr / 60 min) ;


=  (19.2 * 10⁸)
_______________ ;  
         60

_____________________________
Divide EACH SIDE of the fraction by "10" ; to get:
___________

(19.2 * 10⁷)
_______________ ;  
         6

<span>______________________________

</span>⇒  (19.2) ÷ (6) = 3.2 ;  so rewrite as:
_________________________________________________________

3.2 *  10⁷ ; which corresponds with:

Answer choice:  [C]:  " 3.200 * 10⁷  h " .
