Answer:
1. length of the segment = 5 units
2. length of the segment = 9.22 units
Step-by-step explanation:
To find the length of a segment joining two points (x,y) and (x',y') we always use the formula
Distance between the points = √(x-x')²+(y-y')²
In our question the given points are (-1,6) and (-5,3) the distance between them will be = √(-1+5)²+(6-3)² = √4²+3² = √16+9 =√25 = 5 Units
2. Length between the points (-4,1) and (3,7) will be = √(-4-3)²+(1-7)²
= √(-7)²+(-6)² = √49+36 = √85 = 9.22 units
Answer:
2r(d-2)
Step-by-step explanation:
1. 2 and r are both factors of the monomials 2dr and -4
2. Put it as 2r and divide each monomial and put it into parentheses.
3. 2dr/2r is "d" while -4r/2r is -2 since the r cancels out
3. After your done dividing each term b your GCF multiply your GCF to whatever is in the parentheses. 2r: GCF (d-2): Factors
2r(d-2)

$25.50+$1.53=$27.03
8)$66.30×.07=$4.64(actually $4.641 but have to round since it's money)
$66.30+$4.64=$70.94
9)$23.06×.065=$1.50(actually $1.4989 but have to round since it's money)
$23.06+$1.50=$24.56
10)$34.99×.0525=$1.84(actually $1.836975 but have to round since it's money)
$34.99+$$1.84=$36.83
11)$199.99×.0625=$12.50(actually $12.499375 but have to round since it's money)
$199.99+$12.50=$112.49
12)$130.25×.08=$10.42
$130.25+$10.42=$140.37
Basically, to find the percent decrease, we first have to find the percent that it is in:
1576n = 1377
n = 1377/1567
(I used a calculator, if you want me to show work, just ask)
0.8787
This is 87.874%
We subtract this by 100%:
100 - 87.874
12.126%
We need to round to the nearest tenth, so:
12.13%
