The elapsed time is B, 2 hours and 25 minutes.
Answer:
t =1.621860432
Step-by-step explanation:
6e^0.25t = 9
Divide each side by 6
6/6e^0.25t = 9/6
e^0.25t = 3/2
Take the ln of each side
ln e^0.25t = ln (3/2)
.25t = ln (3/2)
Divide each side by .25
.25t/.25 = 1/.25 ln (3/2)
t = 4 ln (3/2)
t =1.621860432
Answer:
A
Step-by-step explanation:
to solve absolute value inequalities you must solve it for when the absolute value is positive and then when it is negative
example, |4| = 4 and -4
first solution will be when we're solving for the positive value:
+(-4x+7) ≥ 27
-4x + 7 ≥ 27
-4x ≥ 20
x ≤ -5 [reverse the symbol when mult or div by a negative]
-(-4x+7) ≥ 27
4x - 7 ≥ 27
4x ≥ 34
x ≥ 34/4 or x ≥ 8 1/2
solution: x ≤ -5 or x ≥ 8.5
(3782 - 192) : 2 = 1795 (first number)
1795 + 192 = 1987 ( second number)
--------------------------
1987 - 1795 = 192
1987 + 1795 = 3782
Answer:
Step-by-step explanation:
d=m+a/n
Firstly, we multiply n to get rid of it by both sides. Since n is dividing a.
d=m+a/n
*n *n
dn=m+a
-m -m
a=dn-m
