Answer:

QR = 5.4

Step-by-step explanation:

These pentagons are similar meaning their corresponding parts have the same scale factor.

AB to PQ = 2 to 1.8

2/1.8 = 10/9 2 ÷ 1.8 = 2 ÷ 1 8/10; 2 ÷ 18/10 ; 2 × 10/18 = 20/18 ; 10/9

AB : PQ = BC : QR

$\frac{10}{9} = \frac{6}{QR}$

10QR = 54

QR = 54/10

QR = 5.4

Geometric sequences HELP ASAP!

Pani-rosa [81]

Given:

The table for a geometric sequence.

To find:

The formula for the given sequence and the 10th term of the sequence.

Solution:

In the given geometric sequence, the first term is 1120 and the common ratio is:

$r=\dfrac{a_2}{a_1}$

$r=\dfrac{560}{1120}$

$r=0.5$

The nth term of a geometric sequence is:

$a_n=ar^{n-1}$

Where a is the first term and r is the common ratio.

Putting $a=1120, r=0.5$ , we get

$a_n=1120(0.5)^{n-1}$

Therefore, the required formula for the given sequence is $a_n=1120(0.5)^{n-1}$ .

We need to find the 10th term of the given sequence. So, substituting $n=10$ in the above formula.

$a_{10}=1120(0.5)^{10-1}$

$a_{10}=1120(0.5)^{9}$

$a_{10}=1120(0.001953125)$

$a_{10}=2.1875$

Therefore, the 10th term of the given sequence is 2.1875.

Carl offered to pay jake $0.25 a square foot to paint his fence. The fence measures 109 feet long and 7 feet wide what is the to

Scorpion4ik [409]

Answer:

Part 1) The total square footage of the fence is $763\ ft^{2}$

Part 2) $\$190.75$

Step-by-step explanation:

Part 1) what is the total square footage of the fence ?

we know that

The area of the fence is equal to

$A=LW$

substitute the values

$A=(109)(7)=763\ ft^{2}$

Part 2) How much will Jake get paid

Using proportion

$\frac{0.25}{1}\frac{\$}{ft^{2}}=\frac{x}{763}\frac{\$}{ft^{2}}\\ \\x=763*0.25\\ \\x=\$190.75$
