By Pythagorean theorem

x²+GF²=EF² ( where G is the point of intersection of perpendicular lines)

now, GF=1/2 EF= 12

x²+12²=24²

x²=24²-12²

x²=432

x=√432

x=12√3

x≈20.78

Consider the arithmetic sequence 10,12,14,16 if n is an integer, which of these functions generate the sequence?

BaLLatris [955]

Given:

The arithmetic sequence is:

10, 12, 14, 16, ...

To find:

The function that generates the given sequence if n is an integer.

Solution:

We have,

10, 12, 14, 16, ...

Here, the first term is 10 and the common difference is:

$d=a_2-a_1$

$d=12-10$

$d=2$

The nth term of an arithmetic sequence is:

$a_n=a+(n-1)d$

Where, a is the first term, d is the common difference and $n\geq 1$ .

Putting $a=10,d=2$ in the above formula, we get

$a_n=10+(n-1)2$

$a_n=10+2n-2$

$a_n=8+2n$

Therefore, the function $a_n=8+2n, n\geq 1$ generates the sequence.

Beach towels are currently selling 3 for 25 or 10 each what is the percent saved by buying 3

Virty [35]

Answer:

I am saving 16.67% when I buy 3 towels together.

Step-by-step explanation:

Beach towels are currently selling 3 for $25 or $10 each.

So, if I purchase 3 towels then I have to pay $25 in place of (3 × 10) = $30.

So, $(30 - 25) = 5 Dollars is saved by me on a price value of $30.

Therefore, the percentage of savings is calculated as $\frac{5}{30} \times 100 = 16.67$ %.

Therefore, I am saving 16.67% when I buy 3 towels together. (Answer)

What is the value of x? x = ?

meriva

 Sum of both the angle will 180 because of linear pair

now, 10x - 20 + 6x + 8 =. 180 

 16x - 12 = 180

16x = 192 

x= 192/16

x = 12

1st angle = 100

2nd is = 80
