Answer:
0.47 and 11.53
Step-by-step explanation:
h = 60t − 5t²
27 = 60t − 5t²
5t² − 60t + 27 = 0
Quadratic formula:
x = [ -b ± √(b² − 4ac) ] / 2a
t = [ -(-60) ± √((-60)² − 4(5)(27)) ] / 2(5)
t = (60 ± √3060) / 10
t = 0.47 or 11.53
<h3>
Answer: 11.55 liters</h3>
=================================================
Work Shown:
275 mL = 275/1000 = 0.275 L
1 cup = 0.275 L
6 cups = 6*0.275 L = 1.65 L
He drinks 1.65 L per day, so over 7 days he drinks a total of 7*1.65 = 11.55 liters.
Answer:
600,000 km²
Step-by-step explanation:
Using the exponential regression calculator : the regression fit obtained for the data is :
36510 * (1.08^x)
After 40 years ;
x = 40
Hence,
y = 36510 * 1.08^40
y = 36510 * 21.72452
y = 793,162.27 km
Hence, y is closest to 800,000 km
Answer: length is 8
Step-by-step explanation:
its just 24 divided by 3 = 8
Hey! since it’s a 5 sided shape it’s area will be 540° so you add up 108+100+90+120=418
the final angle is 122*
then since angles on a straight line is 180° you minus 122 from 180 and x= 58°
