2 ounce bag will cost less than $1.25
6 ounces ÷ 3 = 2 ounces
$3.60 ÷ 3 = $1.20
OR
$3.60 ÷ 6 ounces = $0.60 per ounce
2 ounces = $ 0.60 × 2 = $1.20
Answer:
54.2 mph
Step-by-step explanation:
Since the drivers leave at the same time and travel in directions 90° from each other, their separation speed can be found using the Pythagorean theorem. Let c represent Cynthia's average speed. Then (c-10) will represent Tim's average speed. Their combined separation speed is 70 miles per hour, so we can write ...
70² = c² +(c -10)²
4900 = 2c² -20c +100 . . . . eliminate parentheses
c² -10c -2400 = 0 . . . . . . . . divide by 2; put in standard form
(c -5)² -2425 = 0 . . . . . . . . . rearrange to vertex form
c = 5 ±5√97 . . . . . . . . . . . . solve for c, simplify radical
c ≈ 54.244 ≈ 54.2 . . . . . . . use the positive solution
Cynthia's average speed was 54.2 miles per hour.
The answer is 6t^2+2.5x^2-0.5t-5.4
Answer:
90%
Step-by-step explanation:
50x2=100, 45x2=90, if 45/50=90/100, thats your %
It’s really hard to see the picture
