You take the second decimal, and if it is 5 or over, you increase the first decimal by one. If the number is 17.96,you increase the first decimal by one which gives you 18. If the question asks for 1 decimal place, than put 18.0 :)
Answer:
6 times
Step-by-step explanation:
28claps =12seconds
? = 0.5minutes
60seconds=1minute
? =0.5 minutes
(cross multiply)
60*0.5/1 = ?
?=30seconds
28claps = 12secs
? =30secs
28*30/12 =?
?=70claps
Answer:
<h3>
y = 2(x - 3)² - 20</h3>
Step-by-step explanation:
y = a(x - h)² + k - vertex form of the equation of the parabola with vertex (h, k)
So the equation of the parabola with vertex (3, -20):
y = a(x - 3)² + (-20)
y = a(x - 3)² - 20
The parabola passes through point (7, 12) so if x=7 then y=12
12 = a(7 - 3)² + (-20)
12 +20 = a(4)² - 20 +20
32 = 16a
a = 2
Therefore the equation of the parabola with vertex (3, -20) and that passes through point (7, 12):
y = 2(x - 3)² - 20
Answer:
x = -12
Step-by-step explanation:
−10x + 1 + 7x = 37
Combine like terms
-3x+1 = 37
Subtract 1 from each side
−3x + 1 -1 = 37-1
-3x = 36
Divide each side by -3
-3x/-3 = 36/-3
x = -12
