Answer:
b(10) = 76
Step-by-step explanation:
To find b(10) substitute n = 10 into the formula
b(10) = - 5 + 9(10 - 1) = - 5 + 9(9) = - 5 + 81 = 76
Answer:
33.44 cm²
Step-by-step explanation:
sorry if incorrect
The speed of the object is 12121 m per week.
What does it mean to do speed?
- “Speed” is a street name for various stimulant drugs that teens, young adults and others use to feel more alert and focused, and in some cases, to feel high.
- Some people also use various forms of speed to reduce their appetite. Types of speed include: Amphetamines (used to treat ADHD, narcolepsy, and depression)
The object is moving at a speed of 2 centimeters every 7 seconds.
We need to find the speed in m per week.
2 cm = 0.02 m
1 week = 604800 s
7 s = 
Speed = distance/time
So,
or v = 12121 m/ week
So, the speed of the object is 12121 m per week.

<span>The volume of 100 pages of the book is 20 in</span>³<span>.
Explanation:
Since the book is rectangular, we use the formula for the volume of a rectangular prism: V = l*w*h.
Using the measurements of the book we have
V = 10*8*(3/4) = 80*(3/4) = 240/4 = 60 in</span>³<span>.
However, 100 out of 300 pages means we want 100/300 = 1/3 of the book: 60(1/3) = 60/3 = 20 in</span>³<span>.</span>
