let's firstly convert the mixed fractions to improper fractions and then simply get their difference, our denominators will be 8 and 2, so our LCD will be 8.
![\bf \stackrel{mixed}{27\frac{3}{8}}\implies \cfrac{27\cdot 8+3}{8}\implies \stackrel{improper}{\cfrac{219}{8}}~\hfill \stackrel{mixed}{2\frac{1}{2}}\implies \cfrac{2\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{5}{2}} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{219}{8}-\cfrac{5}{2}\implies \stackrel{\textit{using the LCD of 8}}{\cfrac{(1)219~~-~~(4)5}{8}}\implies \cfrac{219-20}{8}\implies \cfrac{199}{8}\implies 24\frac{7}{8}](https://tex.z-dn.net/?f=%5Cbf%20%5Cstackrel%7Bmixed%7D%7B27%5Cfrac%7B3%7D%7B8%7D%7D%5Cimplies%20%5Ccfrac%7B27%5Ccdot%208%2B3%7D%7B8%7D%5Cimplies%20%5Cstackrel%7Bimproper%7D%7B%5Ccfrac%7B219%7D%7B8%7D%7D~%5Chfill%20%5Cstackrel%7Bmixed%7D%7B2%5Cfrac%7B1%7D%7B2%7D%7D%5Cimplies%20%5Ccfrac%7B2%5Ccdot%202%2B1%7D%7B2%7D%5Cimplies%20%5Cstackrel%7Bimproper%7D%7B%5Ccfrac%7B5%7D%7B2%7D%7D%20%5C%5C%5C%5C%5B-0.35em%5D%20~%5Cdotfill%5C%5C%5C%5C%20%5Ccfrac%7B219%7D%7B8%7D-%5Ccfrac%7B5%7D%7B2%7D%5Cimplies%20%5Cstackrel%7B%5Ctextit%7Busing%20the%20LCD%20of%208%7D%7D%7B%5Ccfrac%7B%281%29219~~-~~%284%295%7D%7B8%7D%7D%5Cimplies%20%5Ccfrac%7B219-20%7D%7B8%7D%5Cimplies%20%5Ccfrac%7B199%7D%7B8%7D%5Cimplies%2024%5Cfrac%7B7%7D%7B8%7D)
Answer:
Option A Center (5,-4) radius 7
Step-by-step explanation:
x^2 +y^2 - 10x +8y - 8= 0
Center(-g,-f)
2gx = - 10x
g = - 5
2fy = 8y
f = 4
Center (5,-4)
Radius = square root of (g^2+f^2 - c)
r = square root of (5^2 + - 4^2 - (-8))
r = square root of (25+16+8)
r = square root of 49
r = 7
The intersection of two planes is a line. :) Hope it works.
Answer:
The distance, in feet, between the strip = 12 feet.
Step-by-step explanation:
From the figure attached in relation with the question, we can deduce that crosswalk is a parallelogram where
CD/AB = CE/AE
CD = 40
CE = 50
AE = 15
Let AB = x
50x = 15 × 40
X = 12
The distance, in feet, between the strip is therefore 12 feet
So what u want to do is find out how much it is per oz, so Mini is $.10 per oz, family is $.08 per oz, and economy is $.09 per oz
Family 28oz is the best buy
