Answer:
30 ounces
Step-by-step explanation:
First you have to make the proportion ounces to servings.
Then you put 12 for ounces and 8 for servings.
After you put an equal sign and after the equal sign you put for ounces an x and for servings 1.
Then you put 8x=12.
after you divide 8x by 8 to get x and 12 by 8 to get 1.5.
Lastly you do 1.5 times 20 to get 30.
First, find the number of quarters that are dated 2005 by multiplying 38*(3/5)
You get 22.8, so you round that to the nearest whole number (23)
Then, since each quarter is worth ($.25) you multiply the number of coins by the worth.
23*.25=$5.75
Answer:
Step-by-step explanation:
line 1 m=y2-y1 / x2-x1 [formula for slope ]
m= 0 - (-3) / 8-(-4)
m= 3 /12
m= 1/4 slope of line 1
line2
m = 2-6 / 0-(-1)
m = -4 / 1
m = -4 slope of line 2
line 3
m = -4 - (-7) / -3 - 6
m = 3 / -9
m = - 1/3 slope of line 3
lines 1 & 2 perpendicular b/c they are reciprocals with a sign change :)
lines 1 & 3 neither.. differet slopes and not reciprocals
lines 2 & 3 perpendicular b/c they are reciprocals with a sign change :)
