Answer:
Step-by-step explanation:
d=20t+1/3, b=30t
20t+1/3=30t
10t=1/3
t=1/30 hr
t=(1/30)60=2 min
Answer:
p34 coop
Step-by-step explanation:
So, since 100% = 128, x should equal 96, and we are trying to find x.
Multiply both sides of the equation by x.
(100/x) * x = (128/96) * x
Cancel out the x's on the left side so
100 = 1.333(x)
75 = x
96 is 75% of 128
Answer:
(D) an = 5n - 1
Step-by-step explanation:
The sequence is generated by substituting a value for n.
The first term of the sequence is 4
So when n = 1
The formula is an = 5n - 1
a1 = 5(1) - 1
a1 = 5 - 1
a1 = 4
The second term of the sequence is 9.
So n = 2
a2 = 5(2) - 1
a2 = 10 - 1
a2 = 9
To find the next value you just have to substitute the next value for n.
