A factory produces some batteries daily. 7/8 of the batteries are packaged immediately. 2/3 of the

frozen [14]

Answer:

$\frac{1}{24}$

Step-by-step explanation:

Let the total number of batteries produced daily be represented by x.

7/8 of the batteries are packaged immediately.

So the total number of packaged batteries = $\frac{7x}{8}$

Remaining batteries = $x-\frac{7x}{8}$

= $\frac{x}{8}$

Two third of the remaining batteries are sent to charity.

So the total number of batteries sent to charity= $\frac{2}{3} * \frac{x}{8}$

= $\frac{x}{12}$

Remaining batteries are faulty.

So the total number of faulty batteries = $\frac{x}{8} - \frac{x}{12}$

= $\frac{3x - 2x}{24}$

= $\frac{x}{24}$

So the faction of batteries which are faulty =

= $\frac{x}{24} \div x$

= $\frac{1}{24}$

Find the first four terms of the sequence<br> An=2a n-1,where a1=3

yKpoI14uk [10]

The first four terms of the sequence are 3 , 6 , 12 , 24

Step-by-step explanation:

We need to find the first four terms of the sequence $a_{n}=2a_{n-1}$

where $a_{1}=3$ to find them do that

Substitute n by 2 in the rule to find $a_{2}$
Substitute n by 3 in the rule to find $a_{3}$
Substitute n by 4 in the rule to find $a_{4}$

∵ $a_{n}=2a_{n-1}$

- Substitute n by 2 to find the 2nd term

∴ $a_{2}=2a_{2-1}$

∴ $a_{2}=2a_{1}$

∵ $a_{1}=3$

∴ $a_{2}=2(3)$

∴ $a_{2}=6$

- Substitute n by 3 to find the 3rd term

∴ $a_{3}=2a_{3-1}$

∴ $a_{3}=2a_{2}$

∵ $a_{2}=6$

∴ $a_{3}=2(6)$

∴ $a_{3}=12$

- Substitute n by 4 to find the 4th term

∴ $a_{4}=2a_{4-1}$

∴ $a_{4}=2a_{3}$

∵ $a_{3}=12$

∴ $a_{4}=2(12)$

∴ $a_{4}=24$

The first four terms of the sequence are 3 , 6 , 12 , 24

HELP DUE IN 10 MINS! Solve for x in the parallelogram below:<br><br> x=??

slavikrds [6]

Answer:

x = 10

Step-by-step explanation:

The opposite angles in a parallelogram are congruent, then

5x - 9 = 3x + 11 ( subtract 3x from both sides )

2x - 9 = 11 ( add 9 to both sides )

2x = 20 ( divide both sides by 2 )

x = 10

HELP DUE IN 15 MINS!<br><br> x =??

Alisiya [41]

Answer:

x = 32

Step-by-step explanation:

Using the Secant and Tangent Intersection Theorem we can say;

(x + 18) (18) = 30²

18x + 324 = 900

18x = 576

x = 32

Hope this helps!
