Answer:
You will save $2 if you buy from Picture Perfect Pizza instead of Pizza Outpost.
Step-by-step explanation:
First we need to find the unit rate of each pizza from each pizza place.
Picture Perfect Pizza: $3÷2 = $1.50
Pizza Outpost: $7÷4 = $1.75
Picture Perfect Pizza: $1.5 * 8 = $12
Pizza Outpost: $1.75*8 = $14
Hello!
First, find angle BOA on the protractor. To do this, look for point B, point O, and point A.
Now, we see some markings that mark what degree point B and point A are at. Point B is marked at 60 degrees, and Point A 40 degrees.
Now, all that's left to do, is subtract the two measurements.
60 degrees - 40 degrees = 20 degrees
Therefore, your answer is 20.
Hope this helps!
B. .33 .3 .275 .25 yup, just gotta get over 20 characters
well, let's say that the first solution is 7 liters and has "x" percent of acid, how much acid total in it? well, 7x, <u>keeping in mind that "x" is a decimal form</u>.
likewise, the second solution is 3 liters and has 15% acid, so how much acid is there in that one? (15/100) * 3 = 0.45, so
