Answer:
is not a rectangle
Step-by-step explanation:
The midpoints of the diagonals are ...
AC midpoint = ((2, -2) +(11, 13))/2 = (13/2, 11/2)
BD midpoint = ((14, 10) +(-2, 1))/2 = (6, 11/2)
The midpoints of the diagonals are different, so this is not a rectangle or any sort of parallelogram.
Answer:
The travel size costs 6 % as much as the regular size. Thus the regular size would be more economical and thus a better buy
Step-by-step explanation:
step 1
<em>Find out the unit rate of a regular tube of toothpaste</em>
we know that
To find out the unit rate, divide the total cost by the total weight
so

step 2
<em>Find out the unit rate of a travel size tube of toothpaste</em>
we know that
To find out the unit rate, divide the total cost by the total weight
so

step 3
Find out the percent of increase
we have that
The unit rate
represent the 100%
so by proportion
Find out what percentage represent the difference ($0.83-$0.78=$0.05 per ounce)

therefore
The travel size costs 6 % as much as the regular size. Thus the regular size would be more economical and thus a better buy
The answer would be option 1, mass divided by volume
I saw the diagram.
1) radii: CD, CG, CF, CE, CH
2) diameter: DG, EF
3) radius: 14cm/2 = 7cm
4) diameter: 14cm because DG is the diameter, its measure is the measure of the diameter.
5) Circumference = 2 π r = 2 * 3.14 * 7cm = 43.96cm
6) Area = π r² = 3.14 * (7cm)² = 3.14 * 49cm² = 153.86 cm²
