How do I solve questions 1,2 and 6?

Talja [164]

Answer:

<h2>1. P = 13.254</h2><h2>2. P = 6.64 + 2x</h2><h2>6. P = 10</h2>

Step-by-step explanation:

$1.\\\text{The length of semicircle:}\\\\l=\dfrac{1}{2}d\pi\\\\d-diameter\\\\d=2.2\\\\\text{substitute:}\\\\l=\dfrac{1}{2}(2.2)\pi=1.1\pi\approx(1.1)(3.14)=3.454\\\\\text{The perimeter of the figure:}\\\\P=2(3.8)+2.2+3.454=13.254$

$2.\\P=2(3.32)+2x=6.64+2x$

$6.\\\text{Look at the picture.}\\\\P=4(2)+2(1)=8+2=10$

Position to term rule of 2, 6, 10, 14, 18<br><br> multiply by _____ and subtract by _____

andreyandreev [35.5K]

Answer:

Please check the explanation.

Step-by-step explanation:

Given the sequence

2, 6, 10, 14, 18

An arithmetic sequence has a constant difference and is defined as

$\:a_n=a_1+\left(n-1\right)d$

compute the differences of all the adjacent terms

$6-2=4,\:\quad \:10-6=4,\:\quad \:14-10=4,\:\quad \:18-14=4$

The difference between all the adjacent terms is the same.

Thus,

$d=4$

and

$a_1=2$

Therefore, the nth term is computed by:

$a_n=4\left(n-1\right)+2$

$a_n=4n-2$

Thus, position to term rule of 2, 6, 10, 14, 18 multiply by __4___ and subtract by __2__.

The sale price of a spring break vacation package was $209.99 the travel agent said by booking early you saved $20.00. Find the

prisoha [69]

Answer:

<em></em> $\%\ decrease = 9.52\%$ <em></em>

<em></em>

Step-by-step explanation:

Given

$Sales\ Price = \$209.99$

$Saved = \$20.00$

Required

Determine the %decrease

First, we need to determine the amount paid

$Amount = Sales\ Price - Amount\ Saved$

$Amount = \$209.99 - \$20.00$

$Amount = \$189.99$

The percentage decrease is the calculated as follows:

$\%\ decrease = -100\% * \frac{Final - Initial}{Initial}$

In this case;

$Initial = Sales\ Price = \$209.99$

$Final = Amount\ Paid = \$189.99$

So; we have:

$\%\ decrease = -100\% * \frac{189.99 - 209.99}{209.99}$

$\%\ decrease = -100\% * \frac{-20}{209.99}$

$\%\ decrease = 100\% * \frac{20}{209.99}$

$\%\ decrease = \frac{2000\%}{209.99}$

$\%\ decrease = 9.52426306015\%$

<em></em> $\%\ decrease = 9.52\%$ <em> (Approximated)</em>
