Hi
35=7+4b in two steps
Step 1 ) Simplify both sides of the equation
35=4b+7
Flip the equation
4b+7=35
Step 2) Subtract 7 from both sides
4b+7-7=35-7
4b=28
b=28/4
b= 7
I hope that's help and have a great night :)
Answer:
<em><u>It will cost $2.52 shipping fee to ship an item that costs $56</u></em>
Step-by-step explanation:
You can get the answer by multiplying 4.5% by $56.
Before you multiply , you need to convert the percent to a decimal which would 0.045.
C = 0.045(56) = 2.52
Answer:
57 days
Step-by-step explanation:
Given that:
t(0) = 26000
Growth rate (S'(t)) = 80t^1/2
Targeted number of subscribers = 49000
Take the integral of the growth rate :
∫80t^1/2dt = [(80t^(1/2 + 1)) / 1/2 + 1] + C
[(80t^(1/2 + 1)) / 1/2 + 1] + C = (80t^3/2) / 3/2 + C
(80t^3/2) * 3/2 + C = (160/3)t^3/2 + C
(160/3)t^3/2 + C
Let C = t(0)
(160/3)t^3/2 + 26000 = 49000
(160/3)t^3/2 = 49000 - 26000
(160/3)t^3/2 = 23000
Multiply both sides by 3/160
t^3/2 = 23000* 3/160
t^3/2 = 69000/160
t^3/2 = 431.25
t^(3/2 * 2/3) = 431.25^2/3
t = 57.080277
t = 57 days (approx.)
The volume of the sphere in cubic inches is option D) 1767.1
<u>Step-by-step explanation</u>:
Given,
The diameter of the sphere = 15 inches
The radius of the sphere, r = diameter/2
=15/2
r =7.5 inches
The volume of the sphere = 4/3 πr^3
⇒ 4/3 π(7.5)^3
⇒ 4/33.14421.86
⇒ 1766.25 cubic inches
⇒ 1767 cubic inches (approximately)
